technical field

The embodiments of the present application relate to the technical field of terminals, and in particular, to a control method of a mobile terminal and a mobile terminal.

Background technique

With the development of mobile communication technology, mobile terminals (such as mobile phones) have gradually become an indispensable part of people's lives, and also provide great convenience for people's work. During the use of the mobile terminal, the held state of the mobile terminal is often used as the basis for adjusting various parameters of the mobile terminal, so as to improve the user experience of the mobile terminal.

For example, the state in which the mobile terminal is held may include multiple holding states such as a bilateral holding state, a left unilateral holding state, a right unilateral holding state, and a free space (FS) state.

At present, most mobile terminals detect the holding state of the mobile terminal through sensors (such as capacitive sensors or touch sensors, etc.) disposed on the side of the mobile terminal. However, detecting the holding state of the mobile terminal by the sensor provided on the side of the mobile terminal has the following problems: (1) the additional sensor will increase the cost; (2) the antenna is usually provided on the side of the mobile terminal, if the Setting the sensor in this locale may affect the performance of the antenna.

SUMMARY OF THE INVENTION

The present application provides a control method of a mobile terminal and a mobile terminal, which can improve the accuracy of identifying the holding state of the mobile terminal, thereby optimizing the performance of the mobile terminal.

In a first aspect, the present application provides a method for controlling a mobile terminal, which can be applied to a mobile terminal. A first antenna and a second antenna are respectively provided in the frame on opposite sides of the mobile terminal.

Wherein, the mobile terminal can acquire the first reflection coefficient of the first antenna at the first working frequency and the second reflection coefficient of the second antenna at the second working frequency. Wherein, the first reflection coefficient and the second reflection coefficient are vectors used to characterize the amplitude and phase of the corresponding signals. Then, the mobile terminal may calculate the vector distances between the first reflection coefficients and the plurality of third reflection coefficients of the first antenna, respectively, and calculate the vector distances between the second reflection coefficients and the plurality of fourth reflection coefficients of the second antenna, respectively. The plurality of third reflection coefficients include the reflection coefficients of the first antenna at the first operating frequency when the first antenna is in different states; the plurality of fourth reflection coefficients include the second antenna when the second antenna is in different states Reflection coefficient at the second operating frequency. Finally, the mobile terminal may compare each calculated vector distance with a preset distance threshold to obtain a comparison result, and control the mobile terminal according to the comparison result. The comparison result is used to indicate the holding state of the mobile terminal.

It can be understood that when the antenna is in different states, the impedance of the antenna is different, and the reflection coefficient of the antenna is different. Wherein, the vector distances between the first reflection coefficient of the first antenna and the different third reflection coefficients are different, and the vector distances between the second reflection coefficient and the different fourth reflection coefficients are different.

Wherein, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in one state is less than the preset distance threshold, it indicates that the first antenna is more likely to be in this state. Similarly, if the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in one state is less than the preset distance threshold, it indicates that the second antenna is more likely to be in this state.

Moreover, when the mobile terminal is in different holding states, the states of the first antenna and the second antenna disposed on the opposite side frames of the mobile terminal may be different. In this way, the state of the first antenna and the state of the second antenna can determine the holding state of the mobile terminal.

To sum up, using the method of the present application to identify the holding state of the mobile terminal according to the reflection coefficients of the first antenna and the second antenna, the accuracy of identifying the holding state of the mobile terminal can be improved. Then, by controlling the mobile terminal according to the holding state of the mobile terminal, the performance of the mobile terminal can be optimized.

In a possible design manner of the first aspect, the vector distance of any two reflection coefficients is the distance of the two reflection coefficients on the Smith chart.

In another possible design manner of the first aspect, the first antenna and the second antenna can support the mobile terminal to recognize the holding state of the mobile terminal when the mobile terminal is in a vertical screen state.

Specifically, the above-mentioned first antenna is arranged on the left side frame of the mobile terminal, and the second antenna is arranged on the right side frame of the mobile terminal. The opposite side borders of the mobile terminal are the left border of the mobile terminal and the right border of the mobile terminal. The above comparison results are used to indicate the holding state of the mobile terminal in the vertical screen state.

In another possible design manner of the first aspect, the first antenna and the second antenna may support the mobile terminal to recognize the holding state of the mobile terminal in a landscape screen scenario.

Specifically, the above-mentioned first antenna is arranged on the upper side frame of the mobile terminal, and the second antenna is arranged on the lower side frame of the mobile terminal. The opposite side frames of the mobile terminal are an upper frame of the mobile terminal and a lower frame of the mobile terminal. The above comparison results are used to indicate the holding state of the mobile terminal in the landscape screen state.

In another possible design manner of the first aspect, the states of the first antenna and the second antenna may include a first state and a second state.

The first state is a state corresponding to the antenna when the side frame where the corresponding antenna is located is not held; the second state is a state corresponding to the antenna when the side frame where the corresponding antenna is located is held.

Specifically, the first state of the first antenna is the state of the first antenna when the side frame where the first antenna is located is not held. The second state of the first antenna is the state of the first antenna when the side frame where the first antenna is located is held. The first state of the second antenna is the state of the second antenna when the side frame where the second antenna is located is not held. The second state of the second antenna is the state of the second antenna when the side frame where the second antenna is located is held.

The above-mentioned plurality of third reflection coefficients include: when the first antenna is in the first state, the reflection coefficient of the first antenna at the first working frequency; and when the first antenna is in the second state, the first antenna is at the first working frequency reflection coefficient.

The above-mentioned plurality of fourth reflection coefficients include: when the second antenna is in the first state, the reflection coefficient of the second antenna at the second working frequency; and when the second antenna is in the second state, the second antenna is at the second working frequency reflection coefficient.

In another possible design manner of the first aspect, the holding state of the mobile terminal may include a double-sided holding state, a free space (Free Space, FS) state, a first one-sided holding state, and a second one-sided holding state holding state.

Wherein, when the first antenna is in the second state and the second antenna is in the second state, the above comparison result indicates that the mobile terminal is in a double-sided holding state. When the first antenna is in the first state and the second antenna is in the first state, the mobile terminal is in the self-FS state. When the first antenna is in the second state and the second antenna is in the first state, the mobile terminal is in the first one-sided holding state. When the first antenna is in the first state and the second antenna is in the second state, the mobile terminal is in the second one-sided holding state.

The above-mentioned two-sided holding state is a state in which both sides of the frame on the opposite sides of the mobile terminal are held by the user. The first one-side holding state is a state in which the first side frame is held by the user and the second side frame is not held by the user among the opposite side frames of the mobile terminal. The above-mentioned second one-side holding state is a state in which the second side frame of the opposite side frames of the mobile terminal is held by the user, and the first side frame is not held by the user.

Wherein, in the above-mentioned vertical screen state, the first side frame is the left frame of the mobile terminal, and the second side frame is the right frame of the mobile terminal. In the above landscape screen scenario, the first side frame is the upper frame of the mobile terminal, and the second side frame is the lower frame of the mobile terminal.

In another possible design manner of the first aspect, the mobile terminal compares each calculated vector distance with a preset distance threshold to obtain a comparison result, including: if the first reflection coefficient and the first antenna are in the second The vector distance of the third reflection coefficient in the state is smaller than the preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the second state is smaller than the preset distance threshold, then the above comparison result indicates that the The mobile terminal is held on both sides.

It can be understood that, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the second state is less than the preset distance threshold, it means that the first reflection coefficient is close to the first antenna in the Smith chart. The third reflection coefficient in the second state. In this case, the probability of the first antenna being in the second state is high. If the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the second state is smaller than the preset distance threshold, it means that the second reflection coefficient on the Smith chart is close to that when the second antenna is in the second state Fourth reflection coefficient. In this case, the possibility that the second antenna is in the second state is high. If both the first antenna and the second antenna are in the second state, the mobile terminal is in a double-sided holding state. For the detailed description of the bilateral holding state, reference may be made to the introduction in the above possible design manners, which will not be repeated here.

In another possible design manner of the first aspect, the mobile terminal in a bilateral holding state can be divided into the following two situations: Case (1): the mobile terminal is in a bilateral holding state in a head-hand model scenario. Situation (2): The mobile terminal is held on both sides in the hand model scenario.

The head-hand model scenario is a scenario in which the mobile terminal is held on both sides and a voice call is made. The hand model scenario is a scenario in which the mobile terminal is held on both sides but no voice call is being made.

In this application, the mobile terminal can judge that the mobile terminal is in the head-hand mode scene or the hand mode scene by the receiver (Receiver) of the mobile terminal being in the ON state or the OFF state. Specifically, after the above-mentioned mobile terminal is in a two-sided holding state, the method of the present application may further include: the mobile terminal judging whether the receiver of the mobile terminal is in an open state; if the receiver is in an open state, the mobile terminal is in a head-hand mode scene; Or, if the receiver is in a closed state, the mobile terminal is in a hand mode scene.

In another possible design manner of the first aspect, the mobile terminal compares each calculated vector distance with a preset distance threshold to obtain a comparison result, including: if the first reflection coefficient and the first antenna are in the second When the vector distance of the third reflection coefficient in the state is less than the preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is less than the preset distance threshold, the above comparison result indicates the movement The terminal is in the first one-sided holding state. For a detailed description of the first one-sided holding state, reference may be made to the introduction in the above possible design manners, which will not be repeated here.

It can be understood that, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the second state is less than the preset distance threshold, it means that the first reflection coefficient is close to the first antenna in the Smith chart. The third reflection coefficient in the second state. In this case, the probability of the first antenna being in the second state is high. If the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is smaller than the preset distance threshold, it means that the second reflection coefficient on the Smith chart is close to that when the second antenna is in the first state Fourth reflection coefficient. In this case, the possibility that the second antenna is in the first state is high. If the first antenna is in the second state and the second antenna is in the first state, then the mobile terminal is in the first one-sided holding state.

In another possible design manner of the first aspect, in the case of considering a laboratory scenario (that is, an electromagnetic radiation ratio (specific absorption rate, SAR) test scenario/state), the holding state of the mobile terminal may also include the first A SAR test status. The first SAR test state is a state in which the distance between the first side frame of the mobile terminal and the human body test model is 0 mm.

In the case of considering a laboratory scenario, according to the above-mentioned first reflection coefficient and second reflection coefficient, the first one-sided holding state and the first SAR test state are indistinguishable. That is, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the second state is less than the preset distance threshold, and the second reflection coefficient and the fourth reflection when the second antenna is in the first state If the vector distance of the coefficient is smaller than the preset distance threshold, the mobile terminal may be in the first one-sided holding state, or may be in the first SAR test state. For the detailed description of the first side frame, reference may be made to the introduction in the above possible design manners, which will not be repeated here.

In this application, the mobile terminal can distinguish the above-mentioned first one-sided holding state or the first SAR test through the third antenna disposed on the back of the mobile terminal, or the change of the first reflection coefficient and the second reflection coefficient in a preset time period condition.

In a possible design manner, the mobile terminal may distinguish the above-mentioned first one-sided holding state and the first SAR test state through the third antenna disposed on the back of the mobile terminal.

Specifically, the mobile terminal further includes a third antenna, and the third antenna is disposed on the back of the mobile terminal. The above-mentioned mobile terminal compares each calculated vector distance with a preset distance threshold to obtain a comparison result, including: if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the second state is less than the preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is less than the preset distance threshold, the mobile terminal detects the fifth reflection coefficient of the third antenna at the third working frequency; the mobile terminal Calculate the vector distance between the fifth reflection coefficient and the sixth reflection coefficient; if the vector distance between the fifth reflection coefficient and the sixth reflection coefficient is greater than or equal to the preset distance threshold, the above comparison result indicates that the mobile terminal is in the first one-sided holding state Or, if the vector distance between the fifth reflection coefficient and the sixth reflection coefficient is less than the preset distance threshold, the above comparison result indicates that the mobile terminal is in the first SAR test state.

The above-mentioned sixth reflection coefficient is the reflection coefficient of the third antenna at the third working frequency when the mobile terminal is in the FS state. For a detailed description of the above-mentioned first one-sided holding state, reference may be made to the introduction in the above-mentioned possible design manners, which will not be repeated here.

It can be understood that when the mobile terminal is in the first one-sided holding state, the user's finger will touch the position of the third antenna on the back of the mobile terminal. In this way, compared to the FS state, when the user holds the mobile terminal in the first one-sided holding state, the impedance of the third antenna may change, and thus the reflection coefficient of the third antenna may also change. However, when the mobile terminal is in the first SAR test state, the human body test model does not touch the position of the third antenna on the back of the mobile terminal. Therefore, compared with the FS state, in the first SAR test state, the impedance of the third antenna does not change, and thus the reflection coefficient of the third antenna does not change. Therefore, if the vector distance between the fifth reflection coefficient and the sixth reflection coefficient is greater than or equal to the preset distance threshold, the mobile terminal is in the first one-sided holding state. If the vector distance between the fifth reflection coefficient and the sixth reflection coefficient is less than the preset distance threshold, the mobile terminal is in the first SAR test state.

In a possible design manner, the mobile terminal may distinguish the above-mentioned first one-sided holding state and the first SAR test state through the change of the first reflection coefficient and the second reflection coefficient in a preset time period.

Specifically, the mobile terminal compares each calculated vector distance with a preset distance threshold to obtain a comparison result, including: if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the second state is less than The preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is less than the preset distance threshold, the mobile terminal determines that the first reflection coefficient or the second reflection coefficient is within the preset duration If the change in the first reflection coefficient or the second reflection coefficient within the preset time period is greater than the preset change threshold, the above comparison result indicates that the mobile terminal is in the first one-sided holding state; or , if the changes of the first reflection coefficient and the second reflection coefficient within the preset time period are both less than or equal to the preset change threshold, the above comparison result indicates that the mobile terminal is in the first SAR test state.

It can be understood that, if the mobile terminal is in the first one-sided holding state, during the process of the user holding the mobile terminal in the first one-sided holding state, there will be a certain degree of relative movement between the mobile terminal and the user. For example, the movement of the user's finger will bring about the relative movement between the mobile terminal and the user. However, if the mobile terminal is in the first SAR test state, the relationship between the first SAR test state and the human body detection model is relatively static. It can be understood that, if the first SAR test state and the user's finger move relative to each other, the above-mentioned first reflection coefficient and/or second reflection coefficient will fluctuate. Therefore, the mobile terminal can distinguish the above-mentioned first one-sided holding state and the first SAR test state according to the change of the first reflection coefficient and the second reflection coefficient in a preset time period.

In another possible design manner of the first aspect, the mobile terminal compares each calculated vector distance with a preset distance threshold to obtain a comparison result, including: if the first reflection coefficient and the first antenna are in the first When the vector distance of the third reflection coefficient in the state is less than the preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the second state is less than the preset distance threshold, the above comparison result indicates the movement The terminal is in a second one-sided holding state. Wherein, for the detailed description of the second one-sided holding state, reference may be made to the introduction in the above possible design manners, which will not be repeated here.

It can be understood that, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than the preset distance threshold, it means that the first reflection coefficient is close to the value of the first antenna in the Smith chart. The third reflection coefficient in the first state. In this case, the probability that the first antenna is in the first state is high. If the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the second state is smaller than the preset distance threshold, it means that the second reflection coefficient on the Smith chart is close to that when the second antenna is in the second state Fourth reflection coefficient. In this case, the possibility that the second antenna is in the second state is high. If the first antenna is in the first state and the second antenna is in the second state, then the mobile terminal is in the second one-sided holding state.

In another possible design manner of the first aspect, when a laboratory scenario (ie, a SAR test scenario/state) is considered, the holding state of the mobile terminal may further include a third SAR test state. The third SAR test state is a state in which the distance between the second side frame of the mobile terminal and the human body test model is 0 mm.

In the case of considering the laboratory scene, according to the above-mentioned first reflection coefficient and second reflection coefficient, the second one-sided holding state and the third SAR test state are indistinguishable. That is, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than the preset distance threshold, and the second reflection coefficient and the fourth reflection when the second antenna is in the second state If the vector distance of the coefficient is smaller than the preset distance threshold, the mobile terminal may be in the second one-sided holding state, or may be in the third SAR test state. For a detailed description of the second side frame, reference may be made to the introduction in the above-mentioned possible design manners, which will not be repeated here.

In this application, the mobile terminal can distinguish the second one-sided holding state or the third SAR test by using the third antenna disposed on the back of the mobile terminal, or the change of the first reflection coefficient and the second reflection coefficient in a preset time period. condition.

It should be noted that the mobile terminal uses the third antenna to distinguish between the second one-sided holding state and the third SAR test state, and the mobile terminal uses the first reflection coefficient and the second reflection coefficient to change in a preset time period. For the method of the second one-sided holding state and the third SAR test state, reference may be made to the method for distinguishing the first one-sided holding state and the first SAR test state in the above-mentioned embodiment, which will not be repeated in this application.

In another possible design manner of the first aspect, the mobile terminal compares each calculated vector distance with a preset distance threshold to obtain a comparison result, including: if the first reflection coefficient and the first antenna are in the first When the vector distance of the third reflection coefficient in the state is less than the preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is less than the preset distance threshold, the above comparison result indicates the movement The terminal is in FS state.

It can be understood that, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than the preset distance threshold, it means that the first reflection coefficient is close to the value of the first antenna in the Smith chart. The third reflection coefficient in the first state. In this case, the probability that the first antenna is in the first state is high. If the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is smaller than the preset distance threshold, it means that the second reflection coefficient on the Smith chart is close to that when the second antenna is in the first state Fourth reflection coefficient. In this case, the possibility that the second antenna is in the first state is high. If the first antenna is in the first state and the second antenna is in the first state, then the mobile terminal is in the FS state.

In another possible design manner of the first aspect, in the case of considering the state of the head mold, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than a preset distance threshold , and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is less than the preset distance threshold, the above comparison result indicates that the mobile terminal is in the FS state or the head mode state. The head model state is a state in which the mobile terminal is not held by the user and a voice call is being performed.

In the present application, the mobile terminal can judge whether the mobile terminal is in the FS state or the head mold state by whether the receiver of the mobile terminal is in the open state or the closed state. Specifically, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than the preset distance threshold, and the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state If the vector distance is less than the preset distance threshold, the mobile terminal judges whether the receiver of the mobile terminal is in the open state; if the receiver is in the open state, the mobile terminal is in the head mold state; or if the receiver is in the closed state, the mobile terminal is in the FS state .

In another possible design manner of the first aspect, considering the head mold state and the laboratory scene, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than The preset distance threshold, and the vector distance between the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state is less than the preset distance threshold, the above comparison result indicates that the mobile terminal is in the FS state, the head mode state, or the second Any of the holding states in the SAR test state.

Wherein, the second SAR test state may include a state in which the mobile terminal is 5 mm away from the human body test model. For example, the second SAR test state may include at least one state such as a 5mm back state, a 5mm right side state, and a 5mm left side state. Among them, the 5mm back state is a state in which the back of the mobile terminal is 5mm away from the human test model. The 5mm right side state is the state in which the right border of the mobile terminal is 5mm away from the human test model. The 5mm left side state is a state in which the left border of the mobile terminal is 5mm away from the human test model.

The mobile terminal can distinguish the above-mentioned second SAR test state from the FS state and the head mold state through the SAR sensor in the mobile terminal. Among them, the SAR sensor is used to collect the distance between the mobile terminal and other objects.

Specifically, if the vector distance between the first reflection coefficient and the third reflection coefficient when the first antenna is in the first state is less than the preset distance threshold, and the second reflection coefficient and the fourth reflection coefficient when the second antenna is in the first state If the vector distance is less than the preset distance threshold, the mobile terminal collects the distance between the mobile terminal and other objects through the SAR sensor; if the distance collected by the SAR sensor is less than the preset value, the above comparison result indicates that the mobile terminal is in the second SAR test state ; Or, if the distance collected by the SAR sensor is greater than or equal to the preset value, the above comparison result indicates that the mobile terminal is in the FS state or the head model state.

Although the mobile terminal can distinguish the above-mentioned second SAR test state through the SAR sensor; however, the FS state and the head model state cannot be distinguished through the SAR sensor. The mobile terminal can judge whether the mobile terminal is in the FS state or the head mold state by whether the receiver of the mobile terminal is in the open state or the closed state.

In another possible design manner of the first aspect, the above-mentioned controlling the mobile terminal according to the comparison result includes: the mobile terminal adjusts the uplink power of the mobile terminal according to the comparison result; or, the mobile terminal switches to use the antenna of the mobile terminal according to the comparison result, The antenna of the mobile terminal includes a first antenna and a second antenna.

In the first one-sided holding mode, the first side frame of the two opposite side frames of the mobile terminal is held by the user, and the second side frame is not held by the user. In the second one-side holding manner, the second side frame is held by the user, and the first side frame is not held by the user.

The mobile terminal also includes a memory and a processor, the memory being coupled to the processor. Wherein, the memory is used to store computer program code, and the computer program code includes computer instructions.

detailed description

Hereinafter, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features. For example, the first camera and the second camera refer to different cameras. Thus, a feature defined as "first" or "second" may expressly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

For ease of understanding, the embodiments of the present application introduce various holding states of the mobile terminal involved in the embodiments of the present application with reference to the accompanying drawings.

(1) Free Space (FS) state of the mobile terminal: the mobile terminal (such as a mobile phone) is placed on a table, placed in a pocket or a backpack, not held by the user, and the mobile terminal is in a standby state. Alternatively, the FS state is an ideal state in which the mobile terminal is in a standby state and is not in contact with any object. For example, as shown in FIG. 1A , the mobile phone 100 (ie, the mobile terminal) is in the FS state.

(2) Bilateral holding state of the mobile terminal: a state in which the user's hand touches two opposite side frames of the mobile terminal and holds the mobile terminal. Wherein, the bilateral holding state may include (Hand Left, HL) state and (Hand Right, HR) state).

For example, as shown in (a) of FIG. 1B , the mobile phone 100 (ie, the mobile terminal) is held by the user's left hand in a bilateral holding state (ie, the HL state); touch the right side frame of the mobile phone 100.

For another example, as shown in (b) of FIG. 1B , the mobile phone 100 is held by the user's right hand in a bilateral holding state (ie, the HR state); the user's right hand is in contact with the right frame of the mobile phone 100, and the user's right hand is in contact with the mobile phone. 100 left border.

For another example, as shown in (c) of FIG. 1B , the mobile phone 100 is held by both hands of the user in a bilateral holding state;

For another example, as shown in (a) of FIG. 1D , the mobile terminal 120 (such as the mobile phone 120 or the tablet computer 120 ) is held by both hands of the user in a bilateral holding state; The right hand contacts the lower side frame of the mobile terminal 120 .

(3) One-sided holding state of the mobile terminal.

For example, as shown in (a) of FIG. 1C , the mobile phone 100 (ie, the mobile terminal) is held by the user's left hand in a one-sided holding state (ie, the left one-sided holding state); the user's left hand contacts the left frame of the mobile phone 100 . As shown in (b) of FIG. 1C , the mobile phone 100 (ie, the mobile terminal) is held by the user's right hand in a one-sided holding state (ie, the right one-sided holding state); the user's right hand contacts the left frame of the mobile phone 100 .

For another example, as shown in (b) of FIG. 1D , the mobile terminal 120 is held by the user's left hand in a one-sided holding state; the user's left hand contacts the upper frame of the mobile phone 100 . As shown in (c) of FIG. 1D , the mobile terminal 120 is held by the user's right hand in a one-sided holding state; the user's right hand contacts the lower side frame of the mobile terminal 120 .

Combined with the above-mentioned two-sided holding state or one-sided holding state, the mobile terminal can be in different working scenarios. The working scenario refers to a scenario defined in the Cellular Telecommunications Industry Association CTIA (Cellular Telecommunications Industry Association CTIA) model in which the mobile terminal works in the above-mentioned various holding states. Various working scenarios of the mobile terminal are introduced here in the embodiments of the present application.

Beside Head Hand (BHH) scenario: the mobile terminal is held by the user (for example, the mobile terminal is in FIG. 1A , (a) in FIG. 1B , (b) in FIG. 1B , (a) in FIG. state shown in (b) in 1C), and a voice call is made. The BHH scene includes the Beside Head Hand Left (BHHL) and the Beside Head Hand Right (BHHR) scene.

Hand model scene: the Hand Only scene. The mobile terminal is held by the user (eg, the mobile terminal is in (a) in FIG. 1B , (b) in FIG. 1B , (c) in FIG. 1B , (a) in FIG. 1C , (b) in FIG. 1C , (a) in FIG. 1D, (b) in FIG. 1D, and (c) in FIG. 1D), and a scene other than a voice call. For example, a user holding a mobile terminal, surfing the Internet, walking, or a black screen of the mobile terminal all belong to the above-mentioned hand model scenario.

Wherein, the above-mentioned head-hand-model scene and hand-model scene are both test scenarios of the mobile terminal. The test scenarios of the mobile terminal include but are not limited to the above-mentioned head and hand model scenarios and hand model scenarios. The test scenario may also include other call scenarios that are different from the above-mentioned head-hand model scenario. The other call scenarios may include: the mobile terminal is not held by the user, and a voice call is performed, such as when the mobile terminal is placed on a table by the user, and the mobile terminal plays an external sound through a speaker and performs voice communication with other electronic devices. .

The test scenarios of the mobile terminal may further include: electromagnetic radiation ratio (specific absorption rate, SAR) test scenarios/states. The SAR test scenario/state may also be referred to as a Body SAR scenario/state, that is, a body SAR scenario, such as a Body SAR scenario when a mobile terminal turns on a hotspot.

Among them, when the mobile terminal turns on the hotspot, radiation may be generated to the user. In this Body SAR scenario, if the radiation exceeds the standard, the mobile terminal needs to adjust the corresponding working parameters (such as antenna transmit power) so that the Body SAR value meets the regulatory requirements (eg, the radiation is within the regulatory requirements).

It should be noted that the above Body SAR states may include Body SAR states at different test distances, such as 0 millimeter (mm) Body SAR state, 5mm Body SAR state, 10mm Body SAR state and 15mm Body SAR state, etc. The above test distance refers to the distance between the mobile terminal (eg, the mobile phone 100 ) and the human body test model.

Wherein, when testing the Body SAR, it is usually necessary to test the front side of the mobile phone 100 (that is, the side where the display screen of the mobile phone 100 is located), the back side or the reverse side (such as the test surface in the back state, that is, the side opposite to the display screen of the mobile phone 100 ). ), top surface (such as the test surface in the following Top state, that is, the plane where the top of the mobile phone 100 is located), bottom surface (that is, the plane where the bottom of the mobile phone 100 is located, such as the plane where the speaker and the microphone are located), the left side (such as the following left The test surface in the side state, that is, the plane where the left side frame of the mobile phone 100 is located) and the right side (such as the following test surface in the right side state, that is, the plane where the right side frame of the mobile phone 100 is located).

Exemplarily, it is assumed that the mobile terminal is the mobile phone 100 shown in FIG. 1A . In the embodiment of the present application, the SAR test state of the mobile phone 100 is introduced by taking the 5mm right side state, the 5mm back state, the 0mm right side state, the 0mm back state, the 0mm top state and the 5mm top state as examples.

The 0mm back state is the SAR test state of the mobile phone 100 when the distance between the back or the back of the mobile phone 100 and the human body test model 10 is 0 mm. For example, (a) in FIG. 1E shows the 0 mm back state in which the cell phone 100 is placed. In the 0mm back state, the back or back of the mobile phone 100 contacts the human body test model 10, that is, the distance between the back or back of the mobile phone 100 and the human body test model 10 is 0 mm.

The 5mm back state is the Body SAR state of the mobile phone 100 when the distance between the back or the back of the mobile phone 100 and the human test model 10 is 5 mm. For example, (b) in FIG. 1E shows the 5mm back state in which the cell phone 100 is placed. In the 5mm back state, the distance between the back of the mobile phone 100 and the human body test model 10 is 5mm.

Among them, setting the mobile phone 100 in the 0mm back state or the 5mm back state is a scene for testing the Body SAR on the back of the mobile phone 100 .

The 0mm right side state is the Body SAR state of the mobile phone 100 when the distance between the right side of the mobile phone 100 and the human test model 10 is 0 mm. For example, (c) in FIG. 1E shows a 0 mm right side state in which the cell phone 100 is placed. In the 0 mm right side state shown in (c) of FIG. 1E , the right side of the mobile phone 100 contacts the human body test model 10 , that is, the distance between the right side of the mobile phone 100 and the human body test model 10 is 0 mm.

5mm right side is the Body SAR state of the mobile phone 100 when the distance between the right side of the mobile phone 100 and the human body test model 10 is 5 mm. For example, (d) in FIG. 1E shows the 5 mm right side state of the mobile phone 100 ; in the 5 mm right side state, the distance between the right side of the mobile phone 100 and the human body test model 10 is 5 mm.

Wherein, setting the mobile phone 100 in the 0mm right side state shown in (c) in FIG. 1E or the 5mm right side state shown in (d) in FIG. 1E is a scene for testing the Body SAR on the right side of the mobile phone 100 .

The 0mm top state is the Body SAR state of the mobile phone 100 when the distance between the top surface of the mobile phone 100 and the human body test model 10 is 0 mm. For example, (e) in FIG. 1E shows a 0 mm top state in which the cell phone 100 is placed. In the 0mm top state shown in (e) of FIG. 1E, the top surface of the mobile phone 100 contacts the human body test model 10, that is, the distance between the top surface of the mobile phone 100 and the human body test model 10 is 0mm.

The 5mm top state is the Body SAR state of the mobile phone 100 when the distance between the top surface of the mobile phone 100 and the human body test model 10 is 5 mm. For example, (f) in FIG. 1E shows the 5 mm top state of the mobile phone 100 ; in the 5 mm top state, the distance between the top surface of the mobile phone 100 and the human body test model 10 is 5 mm.

Wherein, setting the mobile phone 100 in the 0 mm top state shown in (e) in FIG. 1E or the 5 mm top state shown in (f) in FIG. 1E is a scene for testing the Body SAR on the top surface of the mobile phone 100 .

Wherein, in the process of using the mobile terminal, the holding state of the mobile terminal is often used as the basis for adjusting various parameters of the mobile terminal, so as to improve the user experience of the mobile terminal.

For example, when a user uses a mobile terminal and switches between voice services (such as mobile calls) and data services (such as browsing data on the Internet), the mobile terminal can adjust the working state of the antenna accordingly to support the current service type, thereby improving the user experience. experience.

For another example, the mobile terminal can adjust the uplink transmit power of the antenna according to the holding state of the mobile terminal, so as to ensure that the radiation of the antenna does not exceed the standard and improve the security of the user using the mobile terminal.

For another example, the mobile terminal can switch to use an antenna on the mobile terminal whose impedance is not affected by the user's holding according to the holding state of the mobile terminal; in this way, it can be ensured that the signal received by the antenna is not affected by the user's holding, and the mobile terminal can be ensured improve the communication quality of users, thereby improving the communication experience of users. It can be seen that it is particularly important to identify the holding state or working scene of the mobile terminal.

An embodiment of the present application provides a method for controlling a mobile terminal, and the method can be applied to a mobile terminal. At least one antenna is arranged in the side frame of the mobile terminal.

For another example, as shown in Table 1 and (a) of FIG. 1B , both the antenna 101 and the antenna 102 are in the second state, and the mobile phone 100 is in a bilateral holding state. For another example, as shown in Table 1 and (a) in FIG. 1C , the antenna 101 is in the second state, the antenna 102 is in the first state, and the mobile phone 100 is in the left-side holding state. For another example, as shown in Table 1 and (b) of FIG. 1C , the antenna 101 is in the first state, the antenna 102 is in the second state, and the mobile phone 100 is in the right-side holding state.

In other embodiments, the state of the antenna not only includes the above-mentioned first state and second state, but may also include a third state.

For example, as shown in (c) of FIG. 1E, the antenna 101 is in the first state, and the antenna 102 is in the 0mm Body SAR state. For another example, as shown in (d) of FIG. 1E , the antenna 101 is in the first state, and the antenna 102 is in the 5mm Body SAR state.

Exemplarily, in this embodiment of the present application, a mobile terminal (such as a mobile phone 100 ) includes an antenna 101 and an antenna 102 as an example, and Table 2 describes the correspondence between the states of the antenna 101 and the antenna 102 and the SAR test state of the mobile phone 100 .

It can be understood that, compared with the impedance of the antenna in the first state, when the user holds one side of the mobile terminal, the impedance of the antenna disposed on this side of the mobile terminal will change. Consequently, the reflection coefficient of the antenna also changes. The reflection coefficient of the antenna is calculated according to the power of the transmitted signal of the antenna and the power of the reflected signal of the transmitted signal.

When the antenna is in different states, the impedance of the antenna is different, and the reflection coefficient of the antenna is different. The state of each antenna set on the mobile terminal can determine the holding state of the mobile terminal. For example, it is determined whether the mobile terminal is in the FS state or the hand-held state according to the state of each antenna set on the mobile terminal; for another example, it is determined whether the mobile terminal is in the left-side holding state, the right-side holding state, or the two-side holding state. Status, 0mm back status, 0mm top status, 0mm right side status, 0mm left side status, 5mm back status, 5mm top status, 5mm right side status or 5mm left side status and other Body SAR status. Therefore, in this embodiment of the present application, the holding state of the mobile terminal may be determined according to the reflection coefficients of each antenna on the mobile terminal.

Among them, the position change of the reflection coefficient of the antenna in the Smith chart can reflect the change of the impedance of the antenna. The impedance changes of the antenna are different, and the position of the reflection coefficient of the antenna in the Smith chart is different.

Wherein, as shown in FIG. 1H , the working frequency of the antenna is within the frequency range (Frequency Range) of 2.3GHz-2.4GHz.

As shown in Fig. 1H, the curve a in the Smith chart represents the reflection coefficient of the antenna when the mobile phone is in the free space (FS) state; the curve b represents that the mobile phone is held by the user's left hand in a unilateral holding state (that is, the left unilateral holding In the holding state), the reflection coefficient of the antenna; the curve c represents the reflection coefficient of the antenna when the mobile phone is held by the user's right hand in a unilateral holding state (that is, the right unilateral holding state); the curve d represents the mobile phone in the 0mm back state , the reflection coefficient of the antenna.

Please refer to FIG. 1I , which shows a schematic diagram of the position change of the reflection coefficient of an antenna in the mobile phone in the Smith chart when a mobile phone is in different holding states. Among them, as shown in FIG. 1I, the working frequency of the antenna is within the Frequency Range of 1.92GHz-1.98GHz.

As shown in Figure 1I, the curve (1) in the Smith chart represents the reflection coefficient of the antenna when the mobile phone is in the free space (FS) state; the curve (2) represents the reflection coefficient of the antenna when the mobile phone is in the 5mm top state; the curve ( 3) Indicates the reflection coefficient of the antenna when the mobile phone is in the 0mm top state. When the operating frequency of the antenna is 1.95GHz within 1.92GHz-1.98GHz, and the mobile phone is in different holding states, the reflection coefficients of the antenna are respectively the reflection coefficients corresponding to the black dots on each curve shown in Figure 1I.

It can be seen from FIG. 1H and FIG. 1I that when the mobile terminal is in different holding states, the positions of the reflection coefficients of the antennas in the Smith chart are different.

In this embodiment of the present application, the holding state of the mobile terminal can be detected according to the position of the reflection coefficient of each antenna in the mobile terminal in the Smith chart. Therefore, there is no need to add other devices for the mobile terminal, which can reduce the cost of holding state detection. Moreover, the accuracy of the detection results can also be guaranteed.

It should be noted that the reflection coefficient described in the embodiments of the present application is a vector used to characterize the amplitude and phase of the corresponding signal. Exemplarily, when the working frequency of the antenna is 2.35GHz within 2.3GHz-2.4GHz, and the mobile phone is in different holding states, the reflection coefficients of the antenna are the reflections corresponding to the black dots on each curve shown in FIG. 1H . coefficient. For example, when the operating frequency of the antenna is 2.35GHz, and the mobile phone is in the FS state, the reflection coefficient of the antenna is -0.1132-0.5604i as shown in Figure 1H; when the mobile phone is in the HL state, the reflection coefficient of the antenna is as shown in Figure 1H When the mobile phone is in HR state, the reflection coefficient of the antenna is -0.0684+0.5116i as shown in Figure 1H; when the mobile phone is in the 0mm Body state, the reflection coefficient of the antenna is -0.2810+0.3647 as shown in Figure 1H i. Among them, each reflection coefficient (eg -0.2810+0.3647i) shown in Fig. 1H is a linear value, which can be converted into the amplitude and phase of the corresponding signal.

Or, in the above-mentioned at least one antenna, a part of the antennas are antennas specially arranged on the side frame of the mobile phone 100 and used to identify the holding state of the mobile phone 100; the other part of the antennas may be the existing communication antennas in the mobile phone 100, and the communication antennas can be used It is used to identify the holding state of the mobile phone 100 . For example, as shown in (a) of FIG. 1G , the antenna 112 is an existing communication antenna, and the antenna 110 and the antenna 111 may be specially arranged on the side frame of the mobile phone 100 to identify the holding state of the mobile phone 100 . For another example, as shown in (b) of FIG. 1G , the antenna 113 is an existing communication antenna, and the antenna 114 may be an antenna specially arranged on the side frame of the mobile phone 100 to identify the holding state of the mobile phone 100 .

In some embodiments, the method of the embodiments of the present application is described by taking the above-mentioned at least one antenna including the above-mentioned antenna 101 (ie, the first antenna) and the antenna 102 (ie, the second antenna) as an example. As shown in FIG. 1A , the antenna 101 is arranged on the left side frame of the mobile phone 100 , and the antenna 102 is arranged on the right side frame of the mobile phone 100 .

Wherein, through the above-mentioned antenna 101 and antenna 102, it can be identified whether the mobile phone 100 is in any of the following states: FS state, as shown in (a) in FIG. 1B , (b) in FIG. 1B or (c) in FIG. 1B , the unilateral holding state shown in Figure 1C (a) or Figure 1C (b), and the Body SAR state, etc.

Exemplarily, in combination with the contact position between the user and the side frame of the mobile phone 100 when most users hold the mobile phone 100 so that the mobile phone 100 is in the above-mentioned holding state, the antenna 101 and the antenna 102 can be respectively arranged on the left side frame and the lower part of the mobile phone 100. right border. In this way, it can be ensured that when the user holds the mobile phone 100, it can be sensed by the antenna 101 and/or the antenna 102. The sensing that the user is holding the mobile phone 100 by the antenna 101 and/or the antenna 102 specifically refers to: compared with the antenna 101 and/or the antenna 102 in the first state, the reflection of the antenna 101 and/or the antenna 102 when the user is holding the mobile phone 100 The coefficient may vary; the mobile phone 100 can detect the holding state of the mobile phone 100 according to the reflection coefficient of the antenna 101 and/or the antenna 102 .

For example, please refer to FIG. 3A , which shows a schematic diagram of the heat distribution of the mobile phone 100 when the user holds the mobile phone 100 to hold the mobile phone 100 on both sides as shown in (a) of FIG. 1B . As shown in FIG. 3A , the color of the left side frame 310 and the right side frame 320 of the lower part of the mobile phone 100 is darker, indicating that the heat is large. That is, when the user holds the mobile phone 100 in the holding state shown in (a) of FIG. Therefore, arranging the antenna 101 and the antenna 102 on the left side frame 310 and the right side frame 320 of the lower part of the mobile phone 100 respectively can improve the sensitivity of the antenna 101 and the antenna 102 for sensing the holding of the mobile phone 100 .

In some embodiments, the method of the embodiments of the present application is described by taking the mobile phone 100 in the vertical screen state, the antenna 101 disposed on the left side frame of the mobile phone 100, and the antenna 102 disposed on the right side border of the mobile phone 100 as an example. It can be seen from the above embodiment that the antenna 101 and the antenna 102 arranged on the left frame (ie, the first side frame) and the right frame (ie, the second side frame) of the mobile phone 100 can support the mobile phone 100 to recognize The FS state, the left one-sided holding state (ie, the first one-sided holding state), the right one-sided holding state (ie, the second one-sided holding state) and the two-sided holding state of the mobile phone 100 are displayed.

Exemplarily, the mobile phone 100 may execute the method described in this embodiment when it is recognized that the mobile phone 100 is in a vertical screen state. Wherein, the mobile phone 100 may recognize that the mobile phone 100 is in a vertical screen state through one or more sensors (eg, an acceleration sensor or a gyroscope sensor, etc.) in the mobile phone 100 . Specifically, as shown in FIG. 3B , a method for controlling a mobile terminal provided by an embodiment of the present application may include: S301-S303.

S301. The mobile phone 100 detects the first reflection coefficient S1 of the antenna 101 at the first working frequency, and detects the second reflection coefficient S2 of the antenna 102 at the second working frequency.

The first working frequency is the current working frequency of the antenna 101 , and the second working frequency is the current working frequency of the antenna 102 . The first reflection coefficient S1 and the second reflection coefficient S2 are vectors used to characterize the corresponding signal amplitude and phase.

It should be noted that the operating frequencies of the antenna 101 and the antenna 102 may be the same or different. That is to say, the first operating frequency and the second operating frequency may be the same or different.

In the first case, the antenna 101 and the antenna 102 may be existing communication antennas in the mobile phone 100 . The mobile phone 100 can reuse the existing communication antenna in the mobile phone 100 to identify the holding state of the mobile phone 100 .

In the second case, the antenna 101 and the antenna 102 are antennas specially arranged on the side frame of the mobile phone 100 for identifying the holding state of the mobile phone 100 .

In the above two cases, the operating frequencies of the antenna 101 and the antenna 102 may be the same or different. The working frequencies of the antenna 101 and the antenna 102 may be the same, which can facilitate the mobile phone 100 to detect the reflection coefficients of the antenna 101 and the antenna 102 at the same working frequency.

In the above first case, the first operating frequency of the antenna 101 and the second operating frequency of the antenna 102 are variable. In the above second case, the first working frequency of the antenna 101 and the second working frequency of the antenna 102 may be fixed working frequencies, and the first working frequency and the second working frequency are unchanged. This embodiment of the present application does not limit the operating frequencies of the antenna 101 and the antenna 102 .

Among them, some types of mobile phone antennas work at 1/4 wavelength, and other types of mobile phone antennas work at 1/2 wavelength. The working frequency band of the antenna of the mobile phone (eg, the mobile phone 100 ) is inversely proportional to the resonant wavelength of the antenna. For example, the lower the operating frequency band, the larger the physical size of the antenna. In order to ensure that the antenna 101 and the antenna 102 can work in a certain frequency band, the physical dimensions of the antenna 101 and the antenna 102 should be kept within a certain size range.

For example, it is assumed that the operating frequency band of the antenna 101 and the antenna 102 is 2.4 GHz. The physical size of the antenna 101 and the antenna 102 (ie the length of the antenna) may be 40mm. Of course, the physical dimensions of the above-mentioned antenna 101 and antenna 102 include, but are not limited to, 40 mm. For example, the physical dimensions of the antenna 101 and the antenna 102 may be between 15mm-100mm.

Generally speaking, when the user uses the mobile phone 100 in the vertical screen state, the user holds the lower part of the mobile phone 100 . In order to enable the user to hold the mobile phone 100, the antenna 101 and the antenna 102 can sense the user's holding; For example, the distance between one end of the antenna 101 and the antenna 102 close to the lower frame of the mobile phone 100 and the lower frame of the mobile phone 100 may be any value from 0 mm to 20 mm.

It should be noted that the size of the antenna 101 and the size of the antenna 102 include but are not limited to the sizes described in the foregoing embodiments, and the sizes of the antennas on different mobile phones are different. For example, the mobile phone 100 shown in (b) of FIG. 1G , the mobile phone 1500 shown in FIG. 15 , the mobile phone 1600 shown in FIG. 16 , the mobile phone 1700 shown in FIG. 17 , the mobile phone 1800 shown in FIG. The illustrated handset 1900 shows different designs of various antennas.

It can be understood that different antennas have different designs, and their physical dimensions and the positions of the antennas on the mobile phone 100 may also be different. For example, as shown in (b) of FIG. 1G , the mobile phone 100 includes an antenna 113 and an antenna 114 . The antenna 113 is arranged on the left side frame and the lower side frame of the mobile phone 100 , and the antenna 114 is arranged on the right side frame of the mobile phone 100 . Through the antenna 113 and the antenna 114 , the mobile phone 100 can also be supported to recognize the holding state of the mobile phone 100 . However, the physical dimensions of the antennas 113 and 114 may be different from those of the

antennas

101 and 102, and the positions of the antennas 113 and 114 in the mobile phone 100 and the positions of the

antennas

101 and 102 in the mobile phone 100 may be different.

For example, the working frequency band of the antenna 114 may be 2.4 GHz, and the working frequency of the antenna 113 may be at a low frequency. The antenna 114 may be specially arranged on the right side frame of the mobile phone 100 to identify the antenna of the mobile phone 100 . The antenna 113 may be an existing communication antenna in the handset 100 . The mobile phone 100 can reuse the existing antenna 113 in the mobile phone 100 for identifying the mobile phone 100 .

The physical size of the antenna 114 (ie the length of the antenna) may be 40 mm. Of course, the physical size of the above-mentioned antenna 114 includes, but is not limited to, 40 mm. For example, the physical size of the antenna 114 may be between 15mm-80mm. The length of the part of the radiator of the antenna 113 located on the left side frame of the mobile phone 100 may be between 20-100 mm.

The distance between the end of the antenna 114 close to the lower frame of the mobile phone 100 and the lower frame of the mobile phone 100 may be any value from 0 mm to 20 mm. The distance between the end of the part of the radiator of the antenna 113 located on the left side frame of the mobile phone 100 close to the lower side frame of the mobile phone 100 and the lower side frame of the mobile phone 100 is 0 mm.

In this embodiment of the present application, the mobile phone 100 may calculate the first reflection coefficient S1 according to the forward power (eg, forward power 1) and reverse power (eg, reverse power 1) of the signal transmitted by the antenna 101 at the first working frequency; The antenna 102 transmits the forward power (eg, forward power 2) and reverse power (eg, reverse power 2) of the signal at the second operating frequency, and calculates the second reflection coefficient S2. Specifically, the mobile phone 100 can calculate the ratio of the reverse power 1 to the forward power 1 to obtain the first reflection coefficient S1, and calculate the ratio of the reverse power 2 to the forward power 2 to obtain the second reflection coefficient S2.

In this embodiment of the present application, forward power 1 and reverse power 1 are used as examples to introduce forward power and reverse power. Wherein, the forward power 1 is the power of the transmit signal (eg, the transmit signal 1 ) of the antenna 101 ; the reverse power 1 may be the power of the reflected signal of the transmit signal 1 .

Please refer to FIG. 4 , which shows a schematic diagram of a radio frequency circuit of a mobile phone 100 provided by an embodiment of the present application. As shown in FIG. 4 , the mobile phone 100 includes a processor 401 , a radio frequency transceiver chip 402 , a radio frequency front-end circuit 403 , a bidirectional coupler 404 , a power switch 407 , an attenuator 405 , an antenna switch 406 , an antenna 101 and an antenna 102 .

When the mobile terminal shown in FIG. 2 is the mobile phone 100, the processor 401 shown in FIG. 4 is the processor 210 shown in FIG. 2, the radio frequency transceiver chip 402, the radio frequency front-end circuit 403, the two-way coupler 404, the power switch The switch 407 , the attenuator 405 , and the antenna switch 406 are integrated in the mobile communication module 250 or the wireless communication module 260 shown in FIG. 2 , and the antenna 101 and the antenna 102 are included in the antenna 1 or the antenna 2 shown in FIG. 2 .

In this embodiment of the present application, with reference to FIG. 4 , the principle that the radio frequency circuit of the mobile phone 100 transmits signals through the antenna, and the principle that the mobile phone 100 calculates the reflection coefficient of the antenna are introduced.

(1) The principle of transmitting signals.

The processor 401 can transmit radio signals to the radio frequency transceiver chip 402 . The radio frequency transceiver chip 402 can convert the radio signal into a radio frequency signal, and send the radio frequency signal to the radio frequency front-end circuit 403. The RF front-end circuit 403 can filter and amplify the RF signal to obtain a transmit (Transmit, Tx) signal, and then radiate the Tx signal through the antenna through the bidirectional coupler 404 .

The antenna switch 406 may be a frequency band switch, which is used to switch each antenna, that is, the antenna 101 , the antenna 102 or the antenna 408 can be selectively switched through the antenna switch 406 for radiating Tx signals or receiving (Receive, Rx). Signal. For example, the antenna switch 406 may be a double pole double throw switch (dual pole dual throw, DPDT) or a double pole four throw switch (dual pole 4 throw, DP4T) or the like.

(2) The principle that the mobile phone 100 calculates the reflection coefficient of the antenna.

The reflected signal of the Tx signal radiated by the antenna through the bidirectional coupler 404 also passes through the bidirectional coupler 404 . The bidirectional coupler 404 shown in FIG. 4 is used for coupling the forward power of the Tx signal transmitted to the antenna, and coupling the reverse power of the Tx signal reflected back from the antenna (ie, the power of the reflected signal of the Tx signal). The power switch 407 is used for forward power and reverse power detection switching. For example, the power switch 407 may be a DPDT or a single pole double throw switch (single pole dual throw, SPDT).

The bidirectional coupler 404 can feed back the forward power and the reverse power of the antenna (such as the antenna 101 ) switched by the coupled antenna switch 406 to the MRX port of the radio frequency transceiver chip 402 through a power detection path. It should be noted that the bidirectional coupler 404 described in this embodiment of the present application has high requirements on directivity. In this way, the leakage of the forward power to the reverse port can be prevented from affecting the detection accuracy of the reflection coefficient.

Specifically, the bidirectional coupler 404 described in this embodiment of the present application has higher requirements on directivity, which can ensure that the bidirectional coupler 404 has greater isolation between the Tx signal and the reflected signal, and can reduce the mutual influence between the Tx signal and the reflected signal. Among them, the signal strength of the reflected signal is weaker than that of the Tx signal. If the Tx signal leaks, the influence of the leaked Tx signal on the reflected signal will be very large; in this way, the detection accuracy of the reflection coefficient will be greatly reduced. However, if the reflected signal leaks, the influence of the leaked reflected signal on the Tx signal is relatively small, and the detection accuracy of the reflection coefficient will not be greatly affected. Therefore, the bidirectional coupler 404 with higher requirements on directivity is used in the embodiment of the present application, which can prevent the forward power (ie, the power of the Tx signal) from leaking to the reverse port and affecting the detection accuracy of the reflection coefficient.

The forward power and reverse power are demodulated after frequency conversion by the down-conversion circuit inside the MRX port, and then the RF transceiver chip 402 sends the demodulated forward power and reverse power to the processor 401 . The reflection coefficient of the antenna is calculated by the modem (Modem) in the processor 401 according to the received forward power and reverse power. The specific method for the processor 401 to calculate the reflection coefficient according to the forward power and the reverse power of the antenna may refer to the relevant description in the conventional technology, and will not be repeated here.

It can be known from the above embodiment that the antenna switch 406 is used to realize the switching of each antenna. Therefore, when the antenna switch 406 switches to use the antenna 101 to radiate the Tx signal, the radio frequency transceiver chip 402 can detect the forward power and the reverse power of the Tx signal radiated by the antenna 101, and the processor 401 can calculate and obtain the antenna The reflection coefficient of 101, such as the first reflection coefficient S1 of the antenna 101 at the first operating frequency. When the antenna switch 406 switches to use the antenna 102 to radiate the Tx signal, the radio frequency transceiver chip 402 can detect the forward power and reverse power of the Tx signal radiated by the antenna 102, and the processor 401 can calculate the The reflection coefficient, such as the second reflection coefficient S2 of the antenna 102 at the second operating frequency.

It should be noted that there may be errors between the actual forward power and reverse power of the Tx signal radiated by the antenna and the forward power and reverse power of the Tx signal detected by the radio frequency transceiver chip 402 . In this way, there will be a difference between the reflection coefficient S calculated according to the above-mentioned actual forward power and reverse power and the reflection coefficient S' calculated according to the forward power and reverse power detected by the radio frequency transceiver chip 402. . The attenuator 405 shown in FIG. 4 is used to adjust the power (such as forward power and reverse power) entering the radio frequency transceiver chip 402 to reduce or avoid the above errors. For the detailed description of the difference between the reflection coefficient S′ and the reflection coefficient S shown in FIG. 4 , reference may be made to the detailed description in the following embodiments, and details are not repeated here.

It can be understood that when the mobile phone 100 is in different holding states, the impedances of the antennas (eg, the antenna 101 and the antenna 102 ) disposed on the side frame of the mobile phone 100 are different. Therefore, when the mobile phone 100 is in different holding states, even if the operating frequency of the antenna remains unchanged, the forward power of the antenna transmitted signal does not change, and the reverse power of the transmitted signal also changes due to the change of the antenna impedance. As a result, the reflection coefficient of the antenna changes. It can be seen that when the mobile phone 100 is in different holding states, the reflection coefficients of the antennas in the mobile phone 100 may be different. For example, please refer to FIG. 5A , which shows a schematic diagram of the distribution of the reflection coefficient of the antenna 102 on the Smith chart when the mobile phone 100 is in the FS state and the two-sided holding state, respectively. Wherein, as shown in FIG. 5A , the working frequency of the antenna 102 is in the frequency range of 2.4GHz-2.5GHz. It can be seen from FIG. 5A that when the mobile phone 100 is in the FS state and the two-sided holding state, the vector distance of the reflection coefficient of the antenna 102 is large, that is, the antenna impedance of the antenna 102 changes greatly.

It should be noted that when the mobile phone 100 is in the FS state and the two-sided holding state, the vector distance of the reflection coefficient of the antenna 101 and the antenna impedance of the antenna 101 are also similar (not shown in the drawings), that is, the reflection of the antenna 101 The vector distance of the coefficients will also be larger, that is, the change in the antenna impedance of the antenna 101 will also be larger. Therefore, the first reflection coefficient S1 and the second reflection coefficient S2 detected in S301 are related to the holding state of the mobile phone 100 , for example, the first reflection coefficient S1 and the second reflection coefficient S2 can be used to determine the holding state of the mobile phone 100 .

S302 , the mobile phone 100 calculates the vector distances between the first reflection coefficient S1 and the multiple third reflection coefficients of the antenna 101 respectively, and calculates the vector distance between the second reflection coefficient S2 and the multiple fourth reflection coefficients of the antenna 102 respectively.

The vector distance between the first reflection coefficient S1 and any third reflection coefficient of the antenna 101 is: the vector distance between the first reflection coefficient S1 and the third reflection coefficient. The vector distance between the second reflection coefficient S2 and any fourth reflection coefficient of the antenna 102 is: the vector distance between the second reflection coefficient S2 and the fourth reflection coefficient.

It can be understood that the reflection coefficient described in the embodiments of the present application is a vector used to characterize the amplitude and phase of the corresponding signal. Therefore, the vector distance of any two reflection coefficients can also be called the vector distance.

The holding state of the mobile phone 100 may include: FS state and bilateral holding state, left unilateral holding state and right unilateral holding state, and the like.

The mobile phone 100 can determine the holding state of the mobile phone 100 according to the states of the antenna 101 and the antenna 102 . The state of the antenna 101 is determined by the reflection coefficient of the antenna 101 ; the state of the antenna 102 is determined by the reflection coefficient of the antenna 102 .

Therefore, in order to determine the holding state of the mobile phone 100 according to the states of the antenna 101 and the antenna 102; the mobile phone 100 pre-stores the reflection coefficients of the antenna 101 at different operating frequencies when the antenna 101 is in various states; and the antenna 102 is in Reflection coefficients of the antenna 102 at different operating frequencies in various states. For example, the various states described above may include a first state and a second state.

In some embodiments, the plurality of third reflection coefficients of the antenna 101 and the plurality of fourth reflection coefficients of the antenna 102 may be pre-stored in the mobile phone 100 when the mobile phone 100 leaves the factory.

For example, when the mobile phone 100 is shipped from the factory, the mobile phone 100 may pre-store the antenna 101 in the first state and the second state, the reflection coefficients of the antenna 101 at different operating frequencies, and the antenna 102 in the first state and the second state. 102 reflection coefficients at different operating frequencies.

The multiple reflection coefficients (for example, multiple third reflection coefficients and multiple fourth reflection coefficients) pre-stored in the mobile phone 100 may be the test antenna 101 and the antenna 102 in the first state and the second state before the mobile phone 100 leaves the factory. In the state, the reflection coefficients of the antenna 101 and the antenna 102 at different operating frequencies are obtained. Wherein, the plurality of reflection coefficients stored in advance may be obtained through a large number of tests. Among them, the above-mentioned large number of tests may include laboratory tests and tests of actual users holding mobile phones.

In other embodiments, the plurality of third reflection coefficients of the antenna 101 and the plurality of fourth reflection coefficients of the antenna 102 may be obtained by guiding the user to hold the mobile phone in different ways after the mobile phone 100 leaves the factory to measure the reflection coefficients of the antenna 101 and the antenna 102 The reflection coefficient is obtained.

For example, after the mobile phone 100 is shipped from the factory, when the mobile phone 100 is powered on for the first time, the guidance interface 501 shown in FIG. 5B may be displayed. The guide interface 501 shown in FIG. 5B is used to guide the user to hold the mobile phone 100 in a bilateral holding manner. The user holds the mobile phone 100 in the bilateral holding manner shown in FIG. 5B , and the mobile phone 100 can collect the reflection coefficient when the antenna 101 is in the second state and the reflection coefficient when the antenna 102 is in the second state. The mobile phone 100 may prompt the user to hold the mobile phone 100 in the bilateral holding manner shown in FIG. 5B multiple times, so that the mobile phone 100 can collect multiple sets of reflection coefficients when the antenna 101 and the antenna 102 are in the second state. The multiple groups of reflection coefficients may include reflection coefficients of the antenna 101 and the antenna 102 operating at a fixed frequency, or reflection coefficients of the antenna 101 and the antenna 102 operating at different frequencies.

Afterwards, the mobile phone 100 can also display the guide interface 502 shown in FIG. 5C . The guide interface 502 shown in FIG. 5C is used to guide the user to hold the mobile phone 100 in a left-side holding manner. The user holds the mobile phone 100 in a left-side holding manner as shown in FIG. 5C , and the mobile phone 100 can collect the reflection coefficient when the antenna 101 is in the second state and the reflection coefficient when the antenna 102 is in the first state. Wherein, the mobile phone 100 may prompt the user to hold the mobile phone 100 in the left-side holding manner as shown in FIG. 5C many times, so that the mobile phone 100 can collect multiple groups of the antenna 101 in the second state and the antenna 102 in the first state Reflection coefficient. The multiple groups of reflection coefficients may include reflection coefficients of the antenna 101 and the antenna 102 operating at a fixed frequency, or reflection coefficients of the antenna 101 and the antenna 102 operating at different frequencies.

Finally, the mobile phone 100 can also display the guide interface 503 shown in FIG. 5D . The guide interface 503 shown in FIG. 5D is used to guide the user to hold the mobile phone 100 in a right-side holding manner. The user holds the mobile phone 100 in a right-side holding manner as shown in FIG. 5D , and the mobile phone 100 can collect the reflection coefficient when the antenna 101 is in the first state and the reflection coefficient when the antenna 102 is in the second state. Wherein, the mobile phone 100 can prompt the user to hold the mobile phone 100 in the right-side holding manner as shown in FIG. 5C for many times, so that the mobile phone 100 can collect multiple groups of the antenna 101 in the first state and the antenna 102 in the second state Reflection coefficient. The multiple groups of reflection coefficients may include reflection coefficients of the antenna 101 and the antenna 102 operating at a fixed frequency, or reflection coefficients of the antenna 101 and the antenna 102 operating at different frequencies.

The mobile phone 100 can count the reflection coefficients collected when the mobile phone 100 guides the user to hold the mobile phone 100 through the above three guidance interfaces, obtain and save the reflection coefficient of the antenna 101 in the first state and the reflection coefficient of the antenna 101 in the second state. For the reflection coefficient, the reflection coefficient of the antenna 102 in the first state and the reflection coefficient of the antenna 102 in the second state are obtained and stored. The reflection coefficient of the antenna 101 in the first state and the reflection coefficient of the antenna 101 in the second state are the above-mentioned multiple third reflection coefficients. The reflection coefficient of the antenna 102 in the first state and the reflection coefficient of the antenna 102 in the second state are the above-mentioned multiple fourth reflection coefficients.

Further, the mobile phone 100 can also update the plurality of third reflection coefficients of the antenna 101 and the plurality of fourth reflection coefficients of the antenna 102 in a manner that the user does not perceive when the user is using the mobile phone 100.

Among them, the reflection coefficient of the antenna is not only affected by the state of the antenna, but also by the operating frequency of the antenna. For example, when the state of the antenna 102 is different, the reflection coefficient of the antenna 102 at the same working frequency is also different; and when the state of the antenna 102 is the same, the reflection coefficient of the antenna 102 at different working frequencies is also different.

Illustratively, take the operating frequency of the antenna 102 as an example in the frequency range of 2.4GHz-2.5GHz. Please refer to FIG. 6A , which shows a schematic diagram of the distribution of the reflection coefficient of the antenna 101 and the reflection coefficient of the antenna 102 in the Smith chart when the mobile phone 100 is in the double-handed state (HL or HR) and the FS state, respectively.

The curves with white circles and black circles at both ends in the Smith chart 601 shown in FIG. 6A are used to represent the reflection coefficients of the antenna 101 at different operating frequencies, and the curves with white circles and black circles at both ends in the Smith chart 602 The curves are used to represent the reflection coefficients of the antenna 102 at different operating frequencies.

Wherein, when the mobile phone 100 is in different holding states, the states of the antenna 101 and the antenna 102 may be different. It should be noted that, for an antenna of a mobile phone, when the mobile phone 100 is in the same holding state, the state of the antenna is also the same; however, if the working frequency of the antenna is different, the reflection coefficient of the antenna is different. For example, it is assumed that the mobile phone 100 is in a two-sided holding state (eg, HL); at this time, the antenna 101 is in the second state, and the antenna 102 is in the second state. As shown in the Smith chart 601 in FIG. 6A , when the operating frequency of the antenna 101 is 2.4 GHz, the reflection coefficient of the antenna 101 is the reflection coefficient corresponding to the white circle on the curve 2 corresponding to the HL state; the operating frequency of the antenna 101 is 2.5 At GHz, the reflection coefficient of the antenna 101 is the reflection coefficient corresponding to the black circle on the curve 2 corresponding to the HL state.

The multiple third reflection coefficients of the antenna 101 include: reflection coefficients when the antenna 101 is in a first state at the first operating frequency; and reflection coefficients when the antenna 101 is in a second state at the first operating frequency.

For example, taking the above-mentioned first operating frequency as 2.4 GHz as an example, the multiple third reflection coefficients of the antenna 101 may include: in the Smith chart 601 shown in FIG. 6A , the reflection coefficients corresponding to the white circles on the curve 1 and the curve 2 or the reflection coefficient corresponding to the white circle on curve 3.

For another example, taking the above-mentioned first operating frequency as 2.5 GHz as an example, the multiple third reflection coefficients of the antenna 101 may include: in the Smith chart 601 shown in FIG. 6A , the reflection coefficients corresponding to the black circles on the curve 1, and the curve 2 or the reflection coefficient corresponding to the black circle on curve 3.

Wherein, the plurality of fourth reflection coefficients of the antenna 102 include: the reflection coefficients of the antenna 102 when the antenna 102 is in the first state at the second operating frequency; and the reflection coefficients of the antenna 102 when the antenna 102 is in the second state at the second operating frequency .

For example, taking the second operating frequency as 2.4 GHz as an example, the plurality of fourth reflection coefficients of the antenna 102 may include: in the Smith chart 602 shown in FIG. 6A , the reflection coefficients corresponding to the white circles on the curve 1, and the curve 2 or the reflection coefficient corresponding to the white circle on curve 3.

For another example, taking the second operating frequency as 2.5 GHz as an example, the plurality of fourth reflection coefficients of the antenna 102 may include: In the Smith chart 602 shown in FIG. 6A , the plurality of reflection coefficients corresponding to the black circles on the curve 1 , and the reflection coefficient corresponding to the black circle on curve 2 or curve 3.

Please refer to FIG. 6B , which, based on FIG. 6A , shows that the mobile phone 100 is in a 0mm back state, a 0mm right side state, a 5mm back state, a 5mm right side state, a bilateral holding state (HL or HR), and a FS state, respectively. is a schematic diagram of the distribution of the reflection coefficient of the antenna 101 and the reflection coefficient of the antenna 102 in the Smith chart. The detailed description of the reflection coefficient of the antenna 101 and the reflection coefficient of the antenna 102 when the mobile phone 100 shown in FIG. 6B is in different holding states will not be repeated in this embodiment of the present application.

In the embodiment of the present application, the mobile phone 100 cannot distinguish the FS state, the double-sided holding state, and the left single-sided state of the mobile phone 100 according to the reflection coefficients of the first state and the second state of one antenna (such as the antenna 101 and the antenna 102 ). The grip state and the right unilateral grip state. The reason is that when the mobile phone 100 is in different holding states, the state of the antenna may be the same, so that the electromagnetic influence effect of the user on the antenna radiation is the same or similar, and thus the reflection coefficient of the antenna is the same.

For example, when the mobile phone 100 is in the left-side holding state shown in (a) of FIG. 1C , the antenna 101 is in the second state; when the mobile phone 100 is in the bilateral holding state shown in (c) in FIG. 1B , the antenna 101 is in the second state. The antenna 101 is in the second state. Therefore, when the mobile phone 100 is held on the left side and the mobile phone 100 is held on both sides, the electromagnetic influence effect of the user holding the mobile phone 100 on the radiation of the antenna 101 is similar. Therefore, under the same operating frequency, the reflection coefficient of the antenna 101 when the mobile phone 100 is held on the left side is the same as or similar to the reflection coefficient of the antenna 101 when the mobile phone 100 is held on both sides.

For another example, when the mobile phone 100 is in the right-side holding state shown in (b) in FIG. 1C , the antenna 102 is in the second state; when the mobile phone 100 is in the double-side holding state shown in (c) in FIG. 1B , the antenna 102 is in the second state. Therefore, when the mobile phone 100 is held on the right side and the mobile phone 100 is held on both sides, the electromagnetic influence effect of the user holding the mobile phone 100 on the radiation from the antenna 102 is similar. Therefore, under the same operating frequency, the reflection coefficient of the antenna 102 when the mobile phone 100 is held on one side is the same as or similar to the reflection coefficient of the antenna 102 when the mobile phone 100 is held on both sides.

It can be seen that the mobile phone 100 saves each antenna in the first state and the second state, and the reflection coefficients of the antenna at different operating frequencies can support the mobile phone 100 to distinguish the FS state and the bilateral holding state of the mobile phone 100 , left unilateral holding state and right unilateral holding state.

Exemplarily, it is assumed that when the antenna 101 is in the first state, the third reflection coefficient of the antenna 101 at the first working frequency is S3_FS; when the antenna 102 is in the first state, the fourth reflection coefficient of the antenna 102 at the second working frequency is S3_FS for S4_FS.

The mobile phone 100 can use the following formula (1) to calculate the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS, that is, the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS.

The mobile phone 100 can use the following formula (2) to calculate the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS, that is, the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS.

Wherein, the first reflection coefficient S1, the second reflection coefficient S2, the third reflection coefficient S3_FS and the fourth reflection coefficient S4_FS are all vectors. real(S1) is the real part of the first reflection coefficient S1, and imag(S1) is the imaginary part of the first reflection coefficient S1. real(S3_FS) is the real part of the third reflection coefficient S3_FS, and imag(S3_FS) is the imaginary part of the third reflection coefficient S3_FS. real(S2) is the real part of the second reflection coefficient S2, and imag(S2) is the imaginary part of the second reflection coefficient S2. real(S4_FS) is the real part of the fourth reflection coefficient S4_FS, and imag(S4_FS) is the imaginary part of the fourth reflection coefficient S4_FS.

It is assumed that when the antenna 101 is in the second state, the third reflection coefficient of the antenna 101 at the first operating frequency is S3_H; when the antenna 102 is in the second state, the fourth reflection coefficient of the antenna 102 at the second operating frequency is S4_H.

The mobile phone 100 can use the following formula (3) to calculate the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H, that is, the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H.

The mobile phone 100 can use the following formula (2) to calculate the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H, that is, the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H.

Wherein, the above-mentioned third reflection coefficient S3_H and fourth reflection coefficient S4_H are both vectors. real(S3_H) is the real part of the third reflection coefficient S3_H, and imag(S3_H) is the imaginary part of the third reflection coefficient S3_H. real(S4_H) is the real part of the fourth reflection coefficient S4_H, and imag(S4_H) is the imaginary part of the fourth reflection coefficient S4_H.

S303. The mobile phone 100 compares each calculated vector distance with a preset distance threshold to obtain a comparison result, and controls the mobile phone 100 according to the comparison result. The comparison result is used to indicate the holding state of the mobile phone 100 .

The comparison result is used to indicate the holding state of the mobile phone 100 ; or the comparison result corresponds to the holding state of the mobile phone 100 .

It can be understood that the vector distances between the first reflection coefficient S1 and different third reflection coefficients are different, and the vector distances between the second reflection coefficient S2 and different fourth reflection coefficients are different. If the vector distance between the first reflection coefficient S1 and the third reflection coefficient when the antenna 101 is in one state (denoted as state a) is smaller than the preset distance threshold, it means that the antenna 101 is more likely to be in the state a. If the vector distance between the second reflection coefficient S2 and the fourth reflection coefficient when the antenna 102 is in one state (denoted as state b) is smaller than the preset distance threshold, it indicates that the antenna 102 is more likely to be in this state b. That is to say, the mobile phone 100 is more likely to be in the holding state of the mobile phone 100 composed of the state a of the antenna 101 and the state b of the antenna 102 .

For example, if the vector distance between the first reflection coefficient S1 and the third reflection coefficient when the antenna 101 is in the second state is smaller than the preset distance threshold, it indicates that the antenna 101 is more likely to be in the second state. If the vector distance between the second reflection coefficient S2 and the fourth reflection coefficient when the antenna 102 is in the first state is smaller than the preset distance threshold, it indicates that the antenna 102 is more likely to be in the first state. When the antenna 101 is in the second state and the antenna 102 is in the first state, as shown in Table 1, the mobile phone 100 is in the left one-sided holding state (ie, the first one-sided holding state).

For another example, if the vector distance between the first reflection coefficient S1 and the third reflection coefficient when the antenna 101 is in the first state is less than the preset distance threshold, it indicates that the antenna 101 is more likely to be in the first state. If the vector distance between the second reflection coefficient S2 and the fourth reflection coefficient when the antenna 102 is in the second state is smaller than the preset distance threshold, the antenna 102 is more likely to be in the second state. When the antenna 101 is in the first state and the antenna 102 is in the second state, as shown in Table 1, the mobile phone 100 is in the right unilateral holding state (ie, the second unilateral holding state).

Based on this, the mobile phone 100 can compare each calculated distance with a preset distance threshold respectively, and control the mobile phone 100 according to the holding state of the mobile phone 100 indicated by the comparison result. For example, the mobile phone 100 can adjust the uplink transmit power of the antenna in the mobile phone 100 according to the holding state indicated by the comparison result, and switch to use the antenna in the mobile phone 100 .

Specifically, as shown in FIG. 7 , S303 shown in FIG. 3B may include S303a-S303e.

S303a. If the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold, the above comparison result Indicates that the mobile phone 100 is held on both sides.

The above-mentioned preset distance threshold may be a distance threshold value preconfigured in the mobile phone 100 . For example, the preset distance threshold can be any value such as 0.3, 0.4, 0.5, or 0.45. It should be noted that, the preset distance threshold in this embodiment of the present application is a relative distance threshold determined when the radius of the Smith chart is 1. The preset distance threshold has no units. In the following embodiments, the method of the embodiment of the present application is described by taking the preset distance threshold equal to 0.3 as an example.

It can be understood that if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, it means that the first reflection coefficient S1 is close to the third reflection coefficient S3_H on the Smith chart. In this case, the antenna 101 is in the second state. When the antenna 101 is in the second state, the mobile phone 100 may be in the double-sided holding state shown in (a) in FIG. 1B , (b) in FIG. 1B or (c) in FIG. The left unilateral holding state shown in (a) in 1C.

If the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold, it means that the second reflection coefficient S2 is close to the fourth reflection coefficient S4_H on the Smith chart. In this case, the antenna 102 is in the second state. When the antenna 102 is in the second state, the mobile phone 100 may be in the double-sided holding state shown in FIG. 1B (a), FIG. 1B (b) or FIG. 1B (c), or may be in FIG. The right unilateral holding state shown in (b) in 1C.

However, if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold; it means that the antenna 101 is in the second state, and the antenna 102 is in the second state. In this case, the mobile phone 100 can exclude the above-mentioned left unilateral holding state and right unilateral holding state, and the mobile phone is in (a) in FIG. 1B , (b) in FIG. 1B , or ((b) in FIG. 1B . c) The bilateral holding state shown.

After the mobile phone 100 executes S303a, it can identify whether the mobile phone 100 is in a bilateral holding state. In this way, the mobile phone 100 can distinguish between the two-sided holding state and the FS state. Through the solutions of the embodiments of the present application, the mobile phone 100 can be divided into a bilateral holding state and an FS state.

S303b. If the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold, the above comparison result Indicates that the mobile phone 100 is held on the left side.

It can be understood that if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, it means that the first reflection coefficient S1 is close to the third reflection coefficient S3_H on the Smith chart. In this case, the mobile phone 100 may be in the left unilateral holding state shown in (a) in FIG. 1C , or may be in (a) in FIG. 1B , (b) in FIG. 1B , or in (b) in FIG. 1B (c) The bilateral holding state shown in (c) may also be in the 0mm left side state.

If the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold, it means that the second reflection coefficient S2 is close to the fourth reflection coefficient S3_FS on the Smith chart. In this case, the mobile phone 100 may be in the left unilateral holding state shown in (a) of FIG. 1C , may also be in the 0 mm left side state, or may be in the FS state described in FIG. 1A .

However, if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold, the mobile phone 100 can Excluding the above-mentioned bilateral holding state and FS state, the mobile phone 100 is in the 0mm left side state (ie the first SAR test state) or the left unilateral holding state shown in (a) of FIG. 1C (ie the first single side holding state).

Without considering the SAR test scene (ie laboratory scene), if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is less than the preset distance threshold, and the second reflection coefficient S2 and the fourth reflection coefficient S4_FS If the vector distance D2_FS is less than the preset distance threshold, it means that the mobile phone 100 is in the left-side holding state shown in (a) of FIG. 1C .

Without considering the SAR test scenario, after the mobile phone 100 executes S303b, it can identify whether the mobile phone 100 is in a left-side holding state. In this way, the mobile phone 100 can distinguish the left unilateral holding state and the FS state, and can even distinguish the left unilateral holding state, the bilateral holding state, and the right unilateral holding state. Through the solutions of the embodiments of the present application, the mobile phone 100 can distinguish the left unilateral holding state, the bilateral holding state, the right unilateral holding state, and the FS state.

S303c. If the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold, the above comparison result Indicates that the mobile phone 100 is held on the right side.

It can be understood that if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, it means that the first reflection coefficient S1 is close to the third reflection coefficient S3_FS on the Smith chart. In this case, the mobile phone 100 may be in the right unilateral holding state shown in (b) of FIG. 1C , may also be in the FS state shown in FIG. 1A , or may be in the state shown in (c) of FIG. 1E 0mm right side state.

If the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold, it means that the second reflection coefficient S2 is close to the fourth reflection coefficient S3_H on the Smith chart. In this case, the mobile phone 100 may be in the right unilateral holding state shown in (b) of FIG. 1C , may also be in the 0 mm right side state shown in (c) of FIG. 1E , or may be in the state of FIG. 1B (a) in FIG. 1B, (b) in FIG. 1B, or (c) in FIG. 1B in a bilateral holding state.

However, if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold; the mobile phone 100 can Excluding the above-mentioned bilateral holding state, it is determined that the mobile phone 100 is in the right unilateral holding state (ie the second unilateral holding state) or the 0mm right side state (ie the third SAR test state).

Without considering the SAR test scene (ie laboratory scene), if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is less than the preset distance threshold, and the second reflection coefficient S2 and the fourth reflection coefficient S4_H If the vector distance D2_H is less than the preset distance threshold, it means that the mobile phone 100 is in the right unilateral holding state shown in (b) of FIG. 1C .

Without considering the SAR test scenario, after the mobile phone 100 executes S303c, it can identify whether the mobile phone 100 is in the right unilateral holding state. In this way, the mobile phone 100 can realize the distinction between the right unilateral holding state and the FS state, and can even distinguish the right unilateral holding state and the left unilateral holding state and the bilateral holding state. Through the solutions of the embodiments of the present application, the mobile phone 100 can distinguish the right unilateral holding state from the FS state, the bilateral holding state, and the left unilateral holding state.

S303d. If the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold, the above comparison result Indicates that the mobile phone 100 is in the FS state.

If the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold, it means that the second reflection coefficient S2 is close to the fourth reflection coefficient S3_FS on the Smith chart. In this case, the mobile phone 100 may be in the left unilateral holding state shown in (a) of FIG. 1C , may also be in the FS state described in FIG. 1A , or may be in the 0mm left side state.

However, if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance threshold; the mobile phone 100 can Excluding the above-mentioned right unilateral holding state, left unilateral holding state, 0 mm left side state and 0 mm right side state, the mobile phone 100 is in the FS state shown in FIG. 1A .

After the mobile phone 100 executes S303d, it can identify whether the mobile phone 100 is in the FS state. In this way, the mobile phone 100 can realize the distinction between the two-sided holding state, the right one-sided holding state, the left one-sided holding state, and the FS state. Through the solutions of the embodiments of the present application, the mobile phone 100 can distinguish the FS state from the double-sided holding state, the right one-sided holding state, and the left one-sided holding state.

S303e, the mobile phone 100 controls the mobile phone 100 according to the comparison result. The comparison result corresponds to the holding state of the mobile phone 100 , for example, the comparison result is used to indicate the holding state of the mobile phone 100 .

For the specific method for the mobile phone 100 to control the mobile phone 100 according to the comparison result, reference may be made to the relevant descriptions of the embodiments of the present application and the relevant descriptions in the conventional technology, which will not be repeated here.

The antenna 102 is in the second state and the antenna 101 is in the first state when the mobile phone 100 is in the right-side holding state shown in (b) of FIG. 1C . When the mobile phone 100 is in the 0mm right side state shown in (c) of FIG. 1E , the antenna 102 is in the 0mm Body SAR state, and the antenna 101 is in the first state.

When the mobile phone 100 is held on the right side, the electromagnetic influence effect of the user holding the mobile phone 100 on the radiation of the antenna 102 is similar to the electromagnetic influence effect of the human body test model 10 on the radiation of the antenna 102 when the mobile phone 100 is in the 0mm right side state. Therefore, under the same operating frequency, the reflection coefficient of the antenna 102 when the mobile phone 100 is held on the right side is the same or similar to that when the mobile phone 100 is in the 0 mm right side state.

It can be seen that, considering the SAR test scenario, the mobile phone 100 cannot distinguish whether the mobile phone 100 is in the right unilateral holding state or the 0mm right side state by executing S303c. Similarly, when the mobile phone 100 executes S303b, it cannot distinguish whether the mobile phone 100 is in the left-side holding state or the 0mm left-side state.

In some embodiments, in order to distinguish the right one-sided holding state from the 0mm right side state, and to distinguish the left one-sided holding state from the 0mm left side state, a third antenna may be provided on the back of the mobile phone 100 . The third antenna is disposed on the back of the mobile phone 100 near the lower part of the mobile phone 100 . The third antenna is used to support the mobile phone 100 to identify the right unilateral holding state and the 0mm right side state, and to identify the left unilateral holding state and the 0mm left side state.

For example, the third antenna may be a patch antenna (Patch Antenna) operating at 1/2 wavelength. As shown in FIG. 8 , a patch antenna 801 may be provided on the back of the mobile phone 100 . The patch antenna 801 is disposed on the back of the mobile phone 100 , close to the lower part of the mobile phone 100 . For example, as shown in FIG. 8 , the distance between one end of the patch antenna 801 close to the lower side frame 802 (ie, the third side frame) of the mobile phone 100 and the lower side frame 802 is between 1 mm and 20 mm.

Here, as shown in FIG. 8 , the physical size of the patch antenna 801 is M×N. M is between 10 mm and 30 mm, and N is between 10 mm and 30 mm. For example, M=10mm, N=10mm, and the physical size of the patch antenna 801 is 10mm x 10mm. For another example, M=30mm, N=30mm, and the physical size of the patch antenna 801 is 30mm×30mm. For another example, M=20mm, N=30mm, and the physical size of the patch antenna 801 is 20mm×30mm.

Of course, the above-mentioned third antenna can also be other types of antennas, such as a loop antenna (Loop Antenna), an inverted F antenna (Inverted F Antenna, IFA,), a monopole antenna (Monopole Antenna) or a slot antenna (Slot Antenna), Any type of antenna such as a dipole antenna (Dipole Antenna) is not limited in this embodiment of the present application. However, the area of the patch antenna is large, and arranging the patch antenna on the back of the mobile phone 100 can cover the contact surface between the user's finger and the back of the mobile phone 100 to a greater extent when the user holds the mobile phone 100 with one hand. In this way, it is beneficial to improve the accuracy of the mobile phone 100 for recognizing the right unilateral holding state and the 0 mm side state.

It can be understood that when the mobile phone 100 is held in a right-side holding state or a left-side holding state, the user's finger will touch the position of the back patch antenna 801 of the mobile phone 100 . In this way, compared with the FS state, when the user holds the mobile phone 100 in the right unilateral holding state or the left unilateral holding state, the impedance of the patch antenna 801 may change, so that the reflection coefficient of the patch antenna 801 also changes. will change. However, when the mobile phone 100 is in the 0 mm right side state shown in (c) of FIG. 1E , the human body test model 10 does not touch the position where the back patch antenna 801 of the mobile phone 100 is located. Therefore, compared with the FS state, in the 0 mm right side state shown in (c) of FIG. 1E , the impedance of the patch antenna 801 does not change, so the reflection coefficient of the patch antenna 801 does not change. . Based on this, taking the distinction between the right unilateral holding state and the 0mm right side state as an example, as shown in FIG. 9 , S303c shown in FIG. 7 may include S901-S905.

S901. If the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold, the mobile phone 100 detects the sticker The fifth reflection coefficient S3 of the patch antenna 801 at the third operating frequency.

For the specific method for the mobile phone 100 to detect the fifth reflection coefficient of the patch antenna 801 at the third operating frequency, reference may be made to the specific method for the mobile phone 100 to detect the first reflection coefficient S1 and the second reflection coefficient S2 in the above-mentioned embodiment, which is implemented in this application. Examples are not repeated here.

S902 , the mobile phone 100 calculates the vector distance between the fifth reflection coefficient S3 and the sixth reflection coefficient S3_FS of the patch antenna 801 .

The reflection coefficients of the patch antenna 801 at different operating frequencies may be pre-stored in the mobile phone 100 when the mobile phone 100 is in the FS state. The above-mentioned sixth reflection coefficient S3_FS is the reflection coefficient of the patch antenna 801 at the third working frequency when the mobile phone 100 is in the FS state. For the specific method for calculating the vector distance between the fifth reflection coefficient and the sixth reflection coefficient by the mobile phone 100, reference may be made to the method for calculating the vector distance between the first reflection coefficient S1 and the third reflection coefficient by the mobile phone 100 in the above-mentioned embodiment.

S903. The mobile phone 100 determines whether the vector distance between the fifth reflection coefficient S3 and the sixth reflection coefficient S3_FS is smaller than a preset distance threshold.

Specifically, if the vector distance between the fifth reflection coefficient and the sixth reflection coefficient is smaller than the preset distance threshold, it means that the fifth reflection coefficient S3 is close to the sixth reflection coefficient S3_FS on the Smith chart. In this case, the impedance of the patch antenna 801 is not affected by the user's holding; therefore, as described in S904, the mobile phone 100 is in the 0 mm right side state shown in (c) in FIG. 1E.

If the vector distance between the fifth reflection coefficient and the sixth reflection coefficient is greater than or equal to the preset distance threshold, it means that the fifth reflection coefficient S3 is farther from the sixth reflection coefficient S3_FS on the Smith chart. In this case, the impedance of the patch antenna 801 changes under the influence of the user's holding; therefore, as described in S905 , the mobile phone 100 is in the right-side holding state shown in (b) of FIG. 1C .

S904. The above comparison result indicates that the mobile phone 100 is in a 0 mm right side state.

S905 , the above comparison result indicates that the mobile phone 100 is in a right-side holding state.

In this embodiment, the mobile phone 100 can distinguish whether the vector distance between the fifth transmission coefficient S3 and the sixth reflection coefficient S3_FS is greater than the preset distance threshold by detecting the reflection coefficient of the patch antenna 801 (that is, the fifth reflection coefficient S3) The mobile phone 100 is in the 0mm side state or the right unilateral holding state.

Still taking the distinction between the right unilateral holding state and the 0mm right side state as an example, it can be understood that if the mobile phone 100 is in the right unilateral holding state shown in (b) in FIG. During the process of holding the mobile phone 100 in the holding state, the mobile phone 100 and the user will have a certain degree of relative movement. For example, the movement of the user's finger will bring about the relative movement between the mobile phone 100 and the user. However, if the mobile phone 100 is in the 0 mm right side state shown in (c) of FIG. 1E , the relationship between the mobile phone 100 and the human body detection model 10 is relatively stationary. It can be understood that, if the mobile phone 100 and the user's finger move relative to each other, the second reflection coefficient S2 of the antenna 102 will fluctuate.

In other embodiments, the mobile phone 100 can distinguish the 0mm right side state and the right one-side holding state by detecting whether the second reflection coefficient S2 of the antenna 102 fluctuates. Specifically, as shown in FIG. 10 , S303c shown in FIG. 7 may include S1001-S1003.

S1001. If the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than a preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold, the mobile phone 100 determines the Whether the change of the reflection coefficient S2 within the preset time period is greater than the preset change threshold.

The mobile phone 100 performs S301 to periodically detect the first reflection coefficient S1 of the antenna 101 and the second reflection coefficient S2 of the antenna 102 . For example, the above-mentioned preset duration may be any duration such as 5 seconds (s), 10s, or 8s. The preset duration may be pre-configured in the mobile phone 100 ; or, may be set in the mobile phone 100 by the user.

It should be noted that the changes of the second reflection coefficient S2 within the preset time period may include: amplitude changes and phase changes of the second reflection coefficient S2 within the preset time period. The above-mentioned preset change threshold may include a preset amplitude threshold and a preset phase threshold.

Specifically, the change of the second reflection coefficient S2 within the preset time period is greater than the preset change threshold may include: the amplitude change of the second reflection coefficient S2 within the preset period of time is greater than the preset amplitude threshold; and/or, the second reflection coefficient The phase change of S2 within the preset time period is greater than the preset phase threshold.

It can be understood that if the change of the second reflection coefficient S2 within the preset time period is greater than the preset change threshold, it means that there is relative movement between the mobile phone 100 and the user within the preset time period. hold status. If the change of the second reflection coefficient S2 within the preset time period is less than or equal to the preset change threshold, it means that there is no relative movement between the mobile phone 100 and the user within the preset time period. As described in S1003, the mobile phone 100 is in a 0 mm right side state.

S1002. The above comparison result indicates that the mobile phone 100 is in a right-side holding state.

S1003, the above comparison result indicates that the mobile phone 100 is in a state of 0 mm right side.

In this embodiment, the mobile phone 100 can distinguish whether the mobile phone 100 is in the 0mm right side state shown in (c) of FIG. 1E or the picture The right unilateral holding state shown in (b) in 1C. Wherein, by adopting the method of this embodiment, there is no need to add a third antenna (such as the patch antenna 801) in the mobile phone 100, which can save the cost of the mobile phone 100 to realize the recognition of the 0mm right side state and the right side holding state.

It should be noted that the SAR test status (any SAR test status shown in (a)-(f) in FIG. 1E ) is the laboratory test status. In the process of using the mobile phone 100, the user may not distinguish between the 0mm right side state and the right unilateral holding state, and the 0mm left side state and the left unilateral holding state.

After S303a, the mobile phone 100 is held on both sides. Wherein, when the mobile phone 100 is in the above-mentioned two-sided holding state, it can be divided into the following two situations. Situation (1): The mobile phone 100 is in a bilateral holding state in a head-hand mode scenario (ie, a scene in which the mobile phone 100 is held by the user for a voice call). Situation (2): The mobile phone 100 is in a bilateral holding state in a hand model scenario (the mobile phone 100 is held by the user in other scenarios except for a voice call).

In this embodiment of the present application, after S303a, the mobile phone 100 can determine that the mobile phone 100 is in the ON state or the OFF state by whether the handset or receiver of the mobile phone 100 (for example, the receiver 270B in FIG. 2, also referred to as the receiver) is in the ON state or the OFF state. 100 is in the head hand model scene or the hand model scene. Specifically, as shown in FIG. 11 , after S303a shown in FIG. 7 , the method of this embodiment of the present application further includes S1101-S1103.

S1101. The mobile phone 100 determines whether the receiver Receiver of the mobile phone 100 is in an open state.

It can be understood that if the receiver receiver of the mobile phone 100 is in an on state, it means that the receiver receiver of the mobile phone 100 is receiving voice data from other electronic devices, and the mobile phone 100 is conducting voice communication. In this case, as described in S802, the mobile phone 100 is in the head-hand mode scene.

If the receiver Receiver of the mobile phone 100 is in a closed state, it means that the receiver receiver of the mobile phone 100 is not working, and the mobile phone 100 is not performing voice communication. In this case, as described in S803, the mobile phone 100 is in the hand model scene.

S1102, the mobile phone 100 is in a head-hand mode scene.

Wherein, when the mobile phone 100 is in the head-hand mode scene, the mobile phone 100 is relatively close to the user's head. In this case, if the transmit power of the antenna 101 and the antenna 102 is too large, the problem that the radiation generated by the antenna 101 and the antenna 102 to the human body may exceed the standard. Based on this, the mobile phone 100 can adjust the transmit power of the antenna 101 and the antenna 102 to reduce radiation.

S1103, the mobile phone 100 is in a hand model scene.

Wherein, when the mobile phone 100 is in the hand mode scene, the mobile phone 100 can switch to use the antenna of the mobile phone 100 according to the holding state of the mobile phone 100 to improve the communication effect of the mobile phone 100 . For example, when the mobile phone 100 is held on both sides, in order to prevent the user from holding the mobile phone 100 from affecting the transmit power of the antenna 101 and the antenna 102, thereby affecting the communication effect of the mobile phone 100, the mobile phone 100 can switch between the antenna 101 and the antenna 102. other antennas. In this way, the influence of the user holding the mobile phone 100 on the communication effect of the mobile phone 100 can be reduced.

In other embodiments, after S303a shown in FIG. 7 , the mobile phone 100 can also determine whether the mobile phone 100 is close to the user's head according to the data collected by the proximity light sensor; if the mobile phone 100 is close to the user's head, the mobile phone 100 is in the head-hand position Mode scene; if the mobile phone 100 is not close to the user's head, the mobile phone 100 is in the hand mode scene.

It should be noted that, when the mobile phone 100 is held on both sides, the specific method for the mobile phone 100 to distinguish the above-mentioned head-hand model scene or hand model scene includes but is not limited to the methods described in the foregoing embodiments. For other methods by which the mobile phone 100 distinguishes the head-hand-model scene or the hand-model scene, reference may be made to the relevant description in the conventional technology, which will not be repeated in this embodiment of the present application.

In some embodiments, in S303d, if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than a preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance For the distance threshold, the mobile phone 100 may be in the FS state, or may be in any state such as a head model state (also called a head model scene or a single-head scene) or a second SAR test state. The second SAR test state includes a state in which the mobile phone 100 and the human body test model 10 are separated by 5 mm. For example, the second SAR test state may include a 5mm back state or a 5mm right side state, or the like. For example, the head model state may be a scenario in which the mobile phone 100 is not held by the user and a voice call is being made.

Without considering the SAR test scenario, the mobile phone 100 may not distinguish the FS state from the above-mentioned 5mm back state and 5mm right side state. However, the mobile phone 100 needs to distinguish between the FS state and the head model state. The mobile phone 100 can distinguish the above-mentioned FS state and the head model state by judging whether the receiver Receiver of the mobile phone 100 is in an open state.

Specifically, if the receiver Receiver of the mobile phone 100 is in the off state, the mobile phone 100 is in the FS state. If the receiver Receiver of the mobile phone 100 is in an on state, the mobile phone 100 is in a head model state. In this way, the mobile phone 100 can distinguish the head mode state and the FS state.

Considering the SAR test scenario, in order to distinguish the FS state from the 5mm back state or the 5mm right side state, a distance sensor (such as a SAR sensor) may be provided in the mobile phone 100 . The mobile phone 100 can collect data through the SAR sensor to distinguish the above-mentioned FS state, 5mm back state or 5mm right side state.

Wherein, the SAR sensor can be used to collect the distance between the mobile phone 100 and the user or the human test model. Alternatively, the SAR sensor can be used to collect SAR values of electromagnetic waves radiated by the mobile phone 100 . The SAR value is used to characterize the degree of influence of the electromagnetic waves radiated by the mobile phone 100 on the human body or other objects. It can be understood that in the FS state, the 5mm back state or the 5mm right side state, the objects around the mobile phone 100 are different, or the distances between the objects around the mobile phone 100 and the mobile phone 100 are different. Therefore, for objects in the above different states, the SAR generated by the electromagnetic waves radiated by the mobile phone 100 is different. It can be seen that the SAR value collected by the SAR sensor can be used to evaluate the distance between the objects around the mobile phone 100 and the mobile phone 100; therefore, the SAR value collected by the SAR sensor can be regarded as the "SAR sensor collection distance".

Based on this, the mobile phone 100 can distinguish the above-mentioned FS state, 5mm back state or 5mm right side state according to the parameters (such as distance or SAR value) collected by the SAR sensor. For example, if the parameter collected by the SAR sensor is less than the preset value, it means that the mobile phone 100 is in the 5mm back state or the 5mm right side state; if the parameter collected by the SAR sensor is greater than or equal to the preset value, it means that the mobile phone 100 is in the FS state.

It can be understood that the SAR sensors disposed at different positions of the mobile phone 100 can be used to measure the distance between the corresponding position of the mobile phone 100 and the user or the human body test model. For example, a SAR sensor disposed on the back of the mobile phone 100 can be used to measure the distance between the back of the mobile phone 100 and a user or a human test model. For another example, the SAR sensor disposed on the right side of the mobile phone 100 can be used to measure the distance between the right side of the mobile phone 100 and the user or a human test model.

Among them, the parameters collected by the mobile phone 100 through the SAR sensor cannot distinguish the head mode state and the FS state. Based on this, the mobile phone 100 can also determine whether the receiver Receiver of the mobile phone 100 is in an open state. If the receiver Receiver of the mobile phone 100 is in the off state, the mobile phone 100 is in the FS state. If the receiver Receiver of the mobile phone 100 is in an on state, the mobile phone 100 is in a head model state. In this way, the mobile phone 100 can distinguish the head mode state, the FS state and various Body SAR states.

It should be noted that, in the case of considering the SAR test scenario, the specific method for distinguishing the above-mentioned FS state, head mold state, 5mm back state or 5mm right side state in S303d is shown in FIG. 12 . I won't go into details.

For ease of understanding, this embodiment of the present application introduces the flow of the method for controlling the mobile terminal described in the foregoing embodiment with reference to FIG. 12 . Among them, the SAR test state of the mobile phone 100 can not only include 0mm body state (such as 0mm back state, 0mm right side state and 0mm left side state), 5mm body state (such as 5mm back state, 5mm right side state and 5mm left side state) , can also include 10mm Body state (such as 10mm back state, 10mm right side state and 10mm left side state) and so on.

In the embodiments of the present application, the above-mentioned 0mm back state, 0mm right side state, and 0mm left side state are collectively referred to as the 0mm body state, and the 5mm back state, 5mm right side state, and 5mm left side state are collectively referred to as the 5mm body state, and the 10mm body state is collectively referred to as the 5mm body state. The back state, the 10mm right side state and the 10mm left side state are collectively referred to as the 10mm Body state. Taking the SAR test state of the mobile phone 100 including the 0mm Body state, the 5mm Body state and the 10mm Body state as an example, the method of the embodiment of the present application is introduced.

The mobile phone 100 may first execute 1200 shown in FIG. 12 to detect the first reflection coefficient S1 and detect the second reflection coefficient S2. For the detailed description of the first reflection coefficient S1, the second reflection coefficient S2, and 1200, reference may be made to the description of S301 in the foregoing embodiment, which will not be repeated here.

Then, the mobile phone 100 may execute 1201 to perform logical judgment to determine which preset scenario the first reflection coefficient S1 and the second reflection coefficient S2 satisfy. Specifically, the mobile phone 100 executes 1201 to calculate the vector distances between the first reflection coefficient S1 and the plurality of third reflection coefficients of the antenna 101 respectively, and calculate the vector distances between the second reflection coefficients and the plurality of fourth reflection coefficients of the antenna 102 respectively , and each calculated distance is compared with a preset distance threshold to determine which preset scenario the first reflection coefficient S1 and the second reflection coefficient S2 satisfy.

After 1201 shown in FIG. 12 , if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance If the distance threshold is set, it means that both S1 and S2 meet the preset hand-holding scene. In this case, the mobile phone 100 is in the double-sided holding state shown by 1210 in FIG. 12 (ie, the hand model scene or the head-hand model scene). The specific method for the mobile phone 100 to perform 1201-1210 shown in FIG. 12 may refer to the detailed description of S304a in the foregoing embodiment, and will not be repeated here.

Wherein, the mobile phone 100 being in the state of being held on both sides may include two situations. Situation (1): The mobile phone 100 is in a bilaterally held state in the hand model scenario. Situation (2): The mobile phone 100 is in a bilaterally held state in the head-hand model scenario. After 1210 shown in FIG. 12 , the mobile phone 100 can determine whether the Receiver of the mobile phone 100 is in an open state. If the Receiver is enabled (that is, the Receiver is in an enabled state), the mobile phone 100 is in the head-hand mode scene 1211 shown in FIG. 12 . If the Receiver is closed (that is, the Receiver is in a closed state), the mobile phone 100 is in the hand model scene 1212 shown in FIG. 12 .

After 1201 shown in FIG. 12 , if the vector distance D1_H between the first reflection coefficient S1 and the third reflection coefficient S3_H is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance distance threshold; or, if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_H between the second reflection coefficient S2 and the fourth reflection coefficient S4_H is smaller than the preset distance threshold, it means that One of S1 and S2 satisfies the preset hand-holding scene, and the other satisfies the preset FS state. In this case, the mobile phone 100 is in the left unilateral holding state, the right unilateral holding state, or the 0mm Body state (eg, the 0mm right side state or the 0mm left side state) as shown by 1220 in FIG. 12 . The specific method for the mobile phone 100 to execute 1201-1220 shown in FIG. 12 may refer to the detailed descriptions of S304b and S304c in the foregoing embodiment, which will not be repeated here.

Among them, after 1220 shown in FIG. 12 , the mobile phone 100 can detect the fifth reflection coefficient S3 of the third antenna (such as the patch antenna 801 ), and determine whether the vector distance between the fifth reflection coefficient S3 and the sixth reflection coefficient S3_FS is greater than The method of preset distance threshold distinguishes the 0mm Body state from the left unilateral holding state and the right unilateral holding state. The method for distinguishing the 0mm Body state from the left unilateral holding state and the right unilateral holding state by the reflection coefficient of the third antenna of the mobile phone 100 may refer to the detailed descriptions of S901-S905 in the above embodiment, and will not be repeated here.

Alternatively, after 1220 shown in FIG. 12 , the mobile phone 100 can distinguish the 0mm Body state from the left unilateral holding state and the right unilateral state by judging whether the change of S1 and/or S2 within the preset time period is greater than the preset change threshold. holding state. Wherein, for the method for the mobile phone 100 to distinguish the 0mm Body state from the left unilateral holding state and the right unilateral holding state through the changes of S1 and/or S2 within a preset duration, please refer to the detailed descriptions of S1001-S1003 in the above embodiment , will not be repeated here.

Exemplarily, take the mobile phone 100 distinguishing the 0mm Body state from the left unilateral holding state and the right unilateral holding state by judging whether the change of S1 and/or S2 within the preset time period is greater than the preset change threshold. If the change of S1 and/or S2 within the preset time period is greater than the preset change threshold, the mobile phone 100 is in the left unilateral holding state or the right unilateral holding state shown by 1221 in FIG. 12 . If the changes of S1 and S2 within the preset time period are less than or equal to the preset change threshold, the mobile phone 100 is in the 0mm Body state shown by 1222 in FIG. 12 .

After 1201 shown in FIG. 12 , if the vector distance D1_FS between the first reflection coefficient S1 and the third reflection coefficient S3_FS is smaller than the preset distance threshold, and the vector distance D2_FS between the second reflection coefficient S2 and the fourth reflection coefficient S4_FS is smaller than the preset distance distance threshold, it means that S1 and S2 meet the preset FS state. In this case, the mobile phone 100 is in the FS state shown at 1230 in FIG. 12 , the 5mm Body state (eg, the 5mm back state or the 5mm right side state), the 10mm Body state or the head mold state. The specific method for the mobile phone 100 to execute 1201-1230 shown in FIG. 12 may refer to the detailed description of S304d in the foregoing embodiment, and will not be repeated here.

Among them, when the mobile phone 100 is in the FS state (or the head mold state), the 5mm body state or the 10mm body state, the parameters collected by the SAR sensor are different. Therefore, after 1230 shown in FIG. 12 , the mobile phone 100 can distinguish the FS state (or the head mold state), the 5mm body state or the 10mm body state through the parameters collected by the SAR sensor.

If the SAR sensor detection satisfies the 5mm scene (that is, the parameters collected by the SAR sensor match the parameters collected by the SAR sensor when the mobile phone 100 is in the 5mm Body state), the mobile phone 100 is in the 5mm Body state 1231 shown in FIG. 12 . If the SAR sensor detection satisfies the 10mm scene (that is, the parameters collected by the SAR sensor match the parameters collected by the SAR sensor when the mobile phone 100 is in the 10mm Body state), the mobile phone 100 is in the 10mm Body state 1232 shown in FIG. 12 . If the SAR sensor detects a scene exceeding 10mm (that is, the parameters collected by the SAR sensor match the parameters collected by the SAR sensor when the mobile phone 100 is in the X mm Body state; X is greater than 10), the mobile phone 100 is in the head mode state shown in FIG. head model scene or single head scene) 1233 or FS state 1234.

In order to distinguish the FS state and the head model state, the mobile phone 100 can judge whether the Receiver of the mobile phone 100 is in the open state; if the Receiver is turned on (that is, the Receiver is in the open state), the mobile phone 100 is in the head model state 1233 shown in FIG. 12 ; If it is closed (that is, the Receiver is in the closed state), the mobile phone 100 is in the FS state 1234 shown in FIG. 12 .

It can be understood that the Body SAR state (0mm Body state 1222, 5mm Body state 1231 or 10mm Body state 1232 shown in FIG. 12 ), the head-hand model scene 1211 shown in FIG. 12 or FIG. 12 In the case of the head model state 1233 shown, if the transmit power of the antenna 101 and the antenna 102 is too large, the radiation generated by the antenna 101 and the antenna 102 to the human body may exceed the standard, causing damage to the human body. Based on this, the mobile phone 100 may execute 1250 shown in FIG. 12 to adjust the uplink transmit power of the mobile phone 100 according to the SAR requirement. Specifically, the mobile phone 100 can reduce the uplink transmit power of the antenna 101 and/or the antenna 102 so that the SAR value collected by the mobile phone 100 is lower than the SAR requirement. In this way, it can be ensured that the radiation of the antenna 101 and the antenna 102 does not exceed the standard.

When the mobile phone 100 is in the head model scene, the left one-sided holding state, the right one-sided holding state, or the FS state, one or more antennas 101 of the mobile phone 100 are in the FS state. That is, the impedance of the one or more antennas is not affected by the user's holding. For example, when the mobile phone 100 is in the head model scene or the FS state, the antenna 101 and the antenna 102 are both in the FS state, and their impedance will not be affected by the user's holding. For another example, when the mobile phone 100 is in the left-side holding state, the antenna 102 is in the FS state, and its impedance will not be affected by the user's holding. For another example, when the mobile phone 100 is held on the right side, the antenna 101 is in the FS state, and its impedance will not be affected by the user's holding.

It can be understood that if the antenna impedance is affected by the user's holding, then using the antenna to send and receive signals will affect the communication quality of the mobile phone, thereby affecting the user's communication experience. If the antenna impedance will not be affected by the user's holding; then using the antenna to send and receive signals will not affect the communication quality of the mobile phone, thereby ensuring the user's communication experience. Based on this, the mobile phone 100 can execute 1260 shown in FIG. 12 to switch the antenna to improve the communication quality. Specifically, the mobile phone 100 can switch to use the above-mentioned antenna in the FS state. For example, when the mobile phone 100 is held on the left side, the mobile phone 100 can switch to use the antenna 102 instead of the antenna 101 . In this way, the influence of the user's holding on the communication quality of the mobile phone 100 can be reduced, and the communication experience of the user can be improved.

It should be noted that the mobile phone 100 has a dual antenna switching (transmitting antenna switching, TAS) function. For example, when the mobile phone 100 uses the antenna 101 to send and receive signals, if the mobile phone 100 detects that the holding state of the mobile phone 100 is changed to the left-side holding state, the mobile phone 100 can switch to use the antenna 102 instead of the antenna 101 . That is, the mobile phone 100 can perform dual-antenna switching between the antenna 101 and the antenna 102 . In this way, the influence of the user's holding on the communication quality of the mobile phone 100 can be reduced, and the communication experience of the user can be improved.

The mobile phone 100 not only has a TAS function, but also has a multiple antenna switching (multiple antenna switching, MAS) function. For example, as shown in FIG. 4 , the mobile phone 100 includes not only the antenna 101 and the antenna 102 , but also the antenna 408 . In the case where the mobile phone 100 uses the antenna 102 to send and receive signals, if the mobile phone 100 detects that the holding state of the mobile phone 100 is changed to the right-side holding state, the mobile phone 100 can switch to use the antenna 101 and the antenna 408 instead of the antenna 102 . That is, the mobile phone 100 can perform multi-antenna switching among the antenna 101 , the antenna 102 and the antenna 408 . In this way, the influence of the user's holding on the communication quality of the mobile phone 100 can be reduced, and the communication experience of the user can be improved.

Generally speaking, if the vector distance (such as D) of the reflection coefficient of the antenna and the antenna is in a state (denoted as state c, such as FS state) is greater than or equal to the preset distance threshold (such as 0.3), it is considered that The current state of the antenna is distinguishable from the above state c, that is, the antenna is not in the above state c.

The calculation accuracy of the above-mentioned distance D is affected by the calculation accuracy of the above-mentioned reflection coefficient. However, the calculation accuracy of the above reflection coefficient will be affected by the detection accuracy of the reflection coefficient detection circuit shown in FIG. 4 . It can be seen from the above embodiment that there may be errors between the actual forward power and reverse power of the Tx signal radiated by the antenna and the forward power and reverse power of the Tx signal detected by the radio frequency transceiver chip 402 . In this way, the reflection coefficient S shown in FIG. 4 (that is, the reflection coefficient calculated according to the actual forward power and reverse power) and the reflection coefficient S′ shown in FIG. 4 (that is, the reflection coefficient S′ shown in FIG. There is a deviation in the reflection coefficient calculated from the forward power and reverse power.

The reflection coefficient S shown in FIG. 4 and the reflection coefficient S′ shown in FIG. 4 have a mapping relationship shown in the following formula (5).

where a, b, and c are all complex numbers. The specific values of a, b and c are determined by various parameters of the detection circuit of the reflection coefficient. For different detection circuits, the values of a, b and c can be different. The specific values of a, b and c can be obtained through experimental testing and calculation.

Exemplarily, assume a=-0.5492+0.6121i, b=-0.0392+0.0805i, and c=-0.0488-0.0325i. Take the 10MHz bandwidth LTE Band8 with a center frequency of 898 megahertz (MHz) as an example. The measurement and calculation (Measurments vs Calculation in Smitch Chart) 1301 in the Smith chart in FIG. 13 shows a schematic diagram of the positional deviation between the reflection coefficient S' shown in FIG. 4 and the reflection coefficient S shown in FIG. 4 on the Smith chart . Among them, in the Measurments vs Calculation in Smitch Chart 1301 shown in Figure 13, the black dots and the white dots represent the reflection coefficient S' and the reflection coefficient S, respectively.

The distance deviation measurement and calculation (Distance deviation of Measurments vs Calculation) 1302 in FIG. 13 shows a schematic diagram of the deviation between the distance D' calculated according to the reflection coefficient S' and the distance D calculated according to the reflection coefficient S. Wherein, the above-mentioned reflection coefficient S' and reflection coefficient S are both vectors. Amplitude deviation of Measurments vs Calculation 1303 in FIG. 13 shows a schematic diagram of the amplitude deviation of the reflection coefficient S′ and the reflection coefficient S. FIG. The phase deviation measurement and calculation (Phase deviation of Measurments vs Calculation) 1304 in FIG. 13 shows a schematic diagram of the phase deviation of the reflection coefficient S′ and the reflection coefficient S.

It can be seen from the Distance deviation of Measurments vs Calculation 1302 in Figure 13 that the error between the distance D' calculated according to the reflection coefficient S' and the distance D calculated according to the reflection coefficient S does not exceed 0.04. From the Amplitude deviation of Measurments vs Calculation 1303 in Figure 13, it can be known that the amplitude error between the reflection coefficient S' and the reflection coefficient S does not exceed 0.04. It can be known from the Phase deviation of Measurments vs Calculation 1304 in Figure 13 that the phase error between the reflection coefficient S' and the reflection coefficient S does not exceed 4 degrees.

To sum up, the amplitude error and phase error of the reflection coefficient S shown in Figure 4 and the reflection coefficient S' shown in Figure 4, and the distance D and distance caused by the error of the reflection coefficient S and the reflection coefficient S' The errors of D' are relatively small, and do not affect the accuracy of the holding state identification of the mobile phone 100 in the embodiment of the present application.

After the positions of the at least one antenna (eg, the antenna 101 and the antenna 102 ) in the mobile phone 100 are fixed, the different designs of each antenna will also affect the reflection coefficient of the antenna. For example, the design of the position of the feeding point of the antenna will affect the reflection coefficient of the antenna. For another example, the positional design of the antenna slot of the slot antenna also affects the reflection coefficient of the antenna.

Exemplarily, as shown in FIG. 14 , the feeding points of the antenna 101 and the antenna 102 may be set at one end near the lower part of the mobile phone 100 . For example, as shown in FIG. 14 , the feeding point of the antenna 102 (such as a slot antenna) can be set at a distance of 4 mm from the end of the antenna 102 , which is the end of the antenna 102 near the lower part of the mobile phone 100 . When the position of the feeding point of the antenna 102 is shown in FIG. 14 , and the mobile phone 100 is in the FS state and the two-sided holding state (such as the HL state or the HR state), the distribution of the reflection coefficient of the antenna 102 on the Smith chart As shown in Figure 5A.

Exemplarily, as shown in FIG. 15 , the mobile phone 1500 includes an antenna 1501 , and as shown in FIG. 16 , the mobile phone 1600 includes an antenna 1601 . It is assumed that the mobile phone 1500 and the mobile phone 1600 have the same components and parameters except for the antenna 1501 and the antenna 1601; and the position of the antenna 1501 in the mobile phone 1500 is the same as that of the antenna 1601 in the mobile phone 1600, and the size of the antenna 1501 and the antenna 1601 are the same . The difference is that the position of the feed point of the antenna 1501 is different from the position of the feed point of the antenna 1601 , and the position of the antenna slot of the antenna 1501 is different from the position of the antenna slot of the antenna 1601 .

As shown in FIG. 15 , the feeding point of the antenna 1501 (such as a slot antenna) can be set at a distance of 7 mm from one end of the antenna 1501 , which is the end of the antenna 1501 near the lower part of the mobile phone 1500 . As shown in FIG. 15 , the antenna slot of the antenna 1501 (eg, a slot antenna) may be disposed at the other end of the antenna 1501 . When the positions of the feeding point and the antenna slit of the antenna 1501 are shown in FIG. 15 , and the mobile phone 1500 is in the FS state, the HL state and the HR state, the distribution of the reflection coefficient of the antenna 1501 on the Smith chart is shown in FIG. 15 . .

As shown in FIG. 16 , the feeding point of the antenna 1601 (such as a slot antenna) can be set at a position 7 mm away from one end of the antenna 1601 near the upper part of the mobile phone 100 . As shown in FIG. 16 , the antenna slot of the antenna 1601 (eg, slot antenna) can be set at the other end of the antenna 1601 (eg, the end of the antenna 101 near the lower part of the mobile phone 1600 ). When the positions of the feeding point and the antenna slot of the antenna 1601 are shown in Figure 16, and the mobile phone 1600 is in the FS state, the HL state and the HR state, the distribution of the reflection coefficient of the antenna 1601 on the Smith chart is shown in Figure 16 .

The operating frequencies of the antenna 1501 shown in FIG. 15 and the antenna 1601 shown in FIG. 16 are both 1.1 GHz-1.2 GHz. Since the positions of the feeding point and the antenna slit of the antenna 1501 shown in FIG. 15 are different from those of the antenna 1601 shown in FIG. 16 ; therefore, the mobile phone 1500 and the mobile phone 1600 are in the same holding state , the reflection coefficients of the antenna 1501 and the antenna 1601 are different.

For example, comparing FIG. 15 with FIG. 16, it can be seen that the position of the reflection coefficient of the antenna 1501 on the Smith chart when the mobile phone 1500 is in the FS state is different from the position of the reflection coefficient of the antenna 1601 on the Smith chart when the mobile phone 1600 is in the FS state. That is, the reflection coefficients are different; the position of the reflection coefficient of the antenna 1501 on the Smith chart when the mobile phone 1500 is in the HL state is different from the position of the reflection coefficient of the antenna 1601 on the Smith chart when the mobile phone 1600 is in the HL state, that is, the reflection coefficient is different; The position of the reflection coefficient of the antenna 1501 on the Smith chart when the mobile phone 1500 is in HR is different from the position of the reflection coefficient of the antenna 1601 on the Smith chart when the mobile phone 1600 is in the HR state, that is, the reflection coefficient is different.

Exemplarily, the positions of the feed point and the antenna slot of the antenna 101 in the mobile phone 100 shown in FIG. Location is different. As shown in FIG. 6B , the working frequency of the antenna 101 is 2.4GHz-2.5GHz; as shown in FIG. 17 , the working frequency of the antenna 1701 is 2.4GHz-2.5GHz. The operating frequency of the antenna 101 is the same as the operating frequency of the antenna 1701 .

However, since the positions of the feeding point and the antenna slit of the antenna 101 and the antenna 1701 are different; therefore, when the mobile phone 100 and the mobile phone 1700 are in the same holding state, the reflection coefficients of the antenna 1501 and the antenna 1601 are different. For example, comparing the Smith chart 601 shown in FIG. 6B with the Smith chart shown in FIG. 17 , it can be known that the position of the reflection coefficient of the antenna 101 on the Smith chart when the mobile phone 100 is in the FS state is different from that of the antenna when the mobile phone 1700 is in the FS state. The position of the reflection coefficient of 1701 on the Smith chart is different, that is, the reflection coefficient is different; when the mobile phone 100 is in the HL state, the position of the reflection coefficient of the antenna 101 on the Smith chart is different from the reflection coefficient of the antenna 1701 when the mobile phone 1700 is in the HL state. The positions on the Smith chart are different, that is, the reflection coefficients are different; the position of the reflection coefficient of the antenna 101 on the Smith chart when the mobile phone 100 is in the HR state is the same as the reflection coefficient of the antenna 1701 on the Smith chart when the mobile phone 1700 is in the HR state. The position is different, that is, the reflection coefficient is different; the position of the reflection coefficient of the antenna 101 on the Smith chart when the mobile phone 100 is in the 0mm Back state is different from the position of the reflection coefficient of the antenna 1701 on the Smith chart when the mobile phone 1700 is in the 0mm Back state. That is, the reflection coefficients are different; the position of the reflection coefficient of the antenna 101 on the Smith chart when the mobile phone 100 is in the 0mm side state is different from the position of the reflection coefficient of the antenna 1701 on the Smith chart when the mobile phone 1700 is in the 0mm side state, that is, the reflection coefficient different.

Exemplarily, as shown in FIG. 18 , the mobile phone 1800 includes an antenna 1801 ; as shown in FIG. 19 , the mobile phone 1900 includes an antenna 1901 . It is assumed that the mobile phone 1800 and the mobile phone 1900 have the same components and parameters except for the antenna 1801 and the antenna 1901; and the position of the antenna 1801 in the mobile phone 1800 is the same as that of the antenna 1901 in the mobile phone 1900, and the size of the antenna 1801 and the antenna 1901 are the same . The difference is that the position of the feed point of the antenna 1801 is different from the position of the feed point of the antenna 1901 , and the position of the antenna slot of the antenna 1801 is different from the position of the antenna slot of the antenna 1901 .

The operating frequencies of the antenna 1801 shown in FIG. 18 and the antenna 1901 shown in FIG. 19 are both 0.75GHz-0.85GHz. Since the positions of the feeding point and the antenna slit of the antenna 1801 shown in FIG. 18 are different from those of the antenna 1901 shown in FIG. 19 ; therefore, the mobile phone 1800 and the mobile phone 1900 are in the same holding state , the reflection coefficients of antenna 1801 and antenna 1901 are different.

For example, comparing Fig. 18 with Fig. 19, it can be seen that the position of the reflection coefficient of the antenna 1801 on the Smith chart when the mobile phone 1800 is in the FS state is different from the position of the reflection coefficient of the antenna 1901 on the Smith chart when the mobile phone 1900 is in the FS state. That is, the reflection coefficients are different; the position of the reflection coefficient of the antenna 1801 on the Smith chart when the mobile phone 1800 is in the HL state is different from the position of the reflection coefficient of the antenna 1901 on the Smith chart when the mobile phone 1900 is in the HL state, that is, the reflection coefficient is different; The position of the reflection coefficient of the antenna 1801 on the Smith chart when the mobile phone 1800 is in the HR state is different from the position of the reflection coefficient of the antenna 1901 on the Smith chart when the mobile phone 1900 is in the HR state, that is, the reflection coefficient is different.

Further, the reflection coefficient of the antenna is not only affected by the design of the antenna itself, but also by the user's habit of using a mobile terminal (such as the mobile phone 100 ). For example, some users like to add a leather case to their mobile phone. For the same mobile phone, under the same holding state, the influence of the mobile phone being held by the user on the antenna when the holster is added is different from that when the mobile phone is held by the user without the holster. Therefore, in the above two cases, the impedance change of the antenna in the mobile phone is different, and the reflection coefficient of the antenna is different.

For example, as shown in FIG. 15 , when the mobile phone 1500 is in the HL state, the reflection coefficient of the antenna 1501 (reflection coefficient represented by the curve “HL state, 1mm holster” in FIG. 15 ) when the thickness of the holster is added by 1mm is different from that of the When the holster is added, the reflection coefficient of the antenna 1501 (reflection coefficient represented by the curve "HL state" in FIG. 15 ) is different on the Smith chart, that is, the reflection coefficient is different. As shown in FIG. 15 , when the mobile phone 1500 is in the HR state, the reflection coefficient of the antenna 1501 (reflection coefficient represented by the curve “HR state, 1mm holster” in FIG. 15 ) when the thickness of the holster is added by 1mm is different from that without the addition of the holster. The reflection coefficient of the antenna 1501 (reflection coefficient represented by the curve "HR state" in FIG. 15 ) in the case of the sleeve is different in the position on the Smith chart, that is, the reflection coefficient is different.

For example, as shown in FIG. 16 , when the mobile phone 1600 is in the HL state, the reflection coefficient of the antenna 1601 (reflection coefficient represented by the curve “HL state, 1mm holster” in FIG. 16 ) when the thickness of the holster is added by 1mm is different from When the holster is added, the reflection coefficient of the antenna 1601 (reflection coefficient represented by the curve "HL state" in FIG. 16 ) is different in the Smith chart position, that is, the reflection coefficient is different. As shown in Figure 16, when the mobile phone 1600 is in the HR state, the reflection coefficient of the antenna 1601 (reflection coefficient represented by the curve "HR state, 1mm holster" in Figure 16) when the thickness of the holster is added by 1mm is different from that without the addition of the holster. The reflection coefficient of the antenna 1601 (reflection coefficient represented by the curve "HR state" in FIG. 16 ) in the case of the sleeve is different in the position on the Smith chart, that is, the reflection coefficient is different.

For another example, as shown in FIG. 17 , when the mobile phone 1700 is in the HL state, the reflection coefficient of the antenna 1701 (reflection coefficient represented by the curve “HL state, 1mm holster” in FIG. 17 ) when the holster with a thickness of 1 mm is added is the same as the When the holster is not added, the reflection coefficient of the antenna 1701 (reflection coefficient represented by the curve "HL state" in FIG. 17 ) has different positions on the Smith chart, that is, the reflection coefficient is different. As shown in FIG. 17 , when the mobile phone 1700 is in the HR state, the reflection coefficient of the antenna 1701 (reflection coefficient represented by the curve “HR state, 1mm holster” in FIG. 17 ) when the thickness of the holster is added by 1mm is different from that without the addition of the holster. In the case of the sleeve, the reflection coefficient of the antenna 1701 (reflection coefficient represented by the curve "HR state" in FIG. 17 ) is different in the position on the Smith chart, that is, the reflection coefficient is different.

For another example, as shown in FIG. 19 , when the mobile phone 1900 is in the HL state, the reflection coefficient of the antenna 1901 (the reflection coefficient represented by the curve “HL state, 1mm holster” in FIG. 19 ) when the holster with a thickness of 1mm is added is the same as the When the holster is not added, the reflection coefficient of the antenna 1901 (reflection coefficient represented by the curve "HL state" in FIG. 19 ) has different positions on the Smith chart, that is, the reflection coefficient is different. As shown in Figure 19, when the mobile phone 1900 is in the HR state, the reflection coefficient of the antenna 1901 (reflection coefficient represented by the curve "HR state, 1mm holster" in Figure 19) when the thickness of the holster is added by 1mm is different from that without the addition of the holster. In the case of the sleeve, the reflection coefficient of the antenna 1901 (reflection coefficient represented by the curve "HR state" in FIG. 19 ) is different in position on the Smith chart, that is, the reflection coefficient is different.

To sum up, the reflection coefficient of the antenna in the mobile phone will be affected by various factors. In the embodiment of the present application, in order to improve the accuracy of identifying the holding state of the mobile terminal, the mobile terminal may pre-store the reflection coefficients of the antenna in different holding states under the influence of the above-mentioned various factors. For example, the mobile phone 100 can pre-store the reflection coefficients of the antenna (such as the antenna 101 ) at different operating frequencies when the mobile phone 100 is in different holding states when the mobile phone 100 is added with a holster; it can also be stored that the mobile phone 100 is not added In the case of a leather case, when the mobile phone 100 is in different holding states, the reflection coefficients of the antenna (eg, the antenna 101 ) at different operating frequencies. Moreover, when the mobile phone 100 recognizes the holding state, it can detect whether a leather case is added to the mobile phone 100 through a sensor (eg, a magnetic sensor). If a holster is added to the mobile phone 100, the mobile phone 100 can calculate the vector distance between the first reflection coefficient of the antenna 101 and multiple third reflection coefficients of the antenna 101 when the holster is added to identify the holding state of the mobile phone 100. If the mobile phone 100 does not have a holster, the mobile phone 100 can calculate the vector distance between the first reflection coefficient of the antenna 101 and multiple third reflection coefficients of the antenna 101 without the holster to identify the holding state of the mobile phone 100 . In this way, the accuracy of the recognition result can be improved.

In the above-mentioned embodiment, the mobile phone 100 performs S301 to detect not only the first reflection coefficient S1 of the antenna 101 at the first working frequency, but also the second reflection coefficient S2 of the antenna 102 at the second working frequency. In addition, the mobile phone 102 executes S302, not only calculating the vector distances between the first reflection coefficient S1 and a plurality of third reflection coefficients of the antenna 101, but also calculating the vector distances between the second reflection coefficient S2 and a plurality of fourth reflection coefficients of the antenna 102, respectively .

In other embodiments, the mobile phone 100 may only need to detect the reflection coefficient of one of the

antennas

101 and 102 , and calculate the vector distance between the reflection coefficient of one antenna and the reflection coefficient stored in the mobile phone 100 . For example, take the mobile phone 100 detecting the first reflection coefficient S1 of the antenna 101 at the first operating frequency as an example. The mobile phone 100 can detect the first reflection coefficient S1 of the antenna 101 at the first operating frequency, and then calculate the vector distances between the first reflection coefficient S1 and the plurality of third reflection coefficients of the antenna 101 respectively.

If the vector distance between the first reflection coefficient S1 and the third reflection coefficient when the antenna 101 is in the second state is smaller than the preset distance threshold, it indicates that the antenna 101 is more likely to be in the second state. In this case, the mobile phone 100 may be in a double-sided holding state or a left single-sided holding state, and the mobile phone 100 is not in the FS state. At this time, the mobile phone 100 can distinguish the double-sided holding state or the left one-sided holding state of the mobile phone 100 from the FS state. In the case of judging whether the mobile phone 100 is held, or whether the mobile phone 100 is in the FS state, the mobile phone 100 does not need to detect the reflection coefficient of the antenna 102 again.

If the vector distance between the first reflection coefficient S1 and the third reflection coefficient when the antenna 101 is in the first state is smaller than the preset distance threshold, it indicates that the antenna 101 is more likely to be in the first state. In this case, the mobile phone 100 may be in the right-side holding state or the FS state. At this time, the mobile phone 100 cannot distinguish the right-side holding state of the mobile phone 100 from the FS state. Therefore, the mobile phone 100 can detect the second reflection coefficient S2 of the antenna 102 at the second operating frequency, and then calculate the vector distances between the second reflection coefficient S2 and the plurality of fourth reflection coefficients of the antenna 102 respectively.

If the vector distance between the second reflection coefficient S2 and the fourth reflection coefficient when the antenna 102 is in the first state is smaller than the preset distance threshold, it indicates that the antenna 102 is more likely to be in the first state. In this case, the mobile phone 100 is in the FS state. If the vector distance between the second reflection coefficient S2 and the fourth reflection coefficient when the antenna 102 is in the second state is smaller than the preset distance threshold, it indicates that the antenna 102 is more likely to be in the second state. In this case, the mobile phone 100 is held on the right side.

In this embodiment, the mobile phone 100 may only need to detect the reflection coefficient of any one of the

antennas

101 and 102, and calculate the vector distance between the reflection coefficient of any antenna and the reflection coefficient stored in the mobile phone 100, and then it can be determined Whether the mobile phone 100 is held, or whether the mobile phone 100 is in the FS state.

It should be noted that the positions of the antennas shown in the dotted boxes shown in FIG. 1D (a), FIG. 1D (b), and FIG. 1D (c) are only schematic. The above-mentioned antenna may be arranged on the frame of the tablet computer 120, or may be arranged at a position on the tablet computer 120 close to the frame (eg, inside the frame of the mobile phone 100). This embodiment of the present application does not limit the position of the antenna on the frame.

The tablet computer 120 can perform the method described in this embodiment when recognizing that the tablet computer 120 is in a landscape scene, and identify the FS state, the left unilateral holding state, the right unilateral holding state, and the The state of holding both sides and so on.

It should be noted that, the tablet computer 120 may recognize that the tablet computer 120 is in a landscape screen scene through one or more sensors (such as an acceleration sensor or a gyroscope sensor, etc.) in the tablet computer 120. For the method for the tablet computer 120 to recognize the holding state of the tablet computer 120 in the landscape screen scene, reference may be made to the method for the mobile phone 100 to recognize the holding state of the mobile phone 100 in the vertical screen state in the above-mentioned embodiment.
