Background
With the development of mobile communication technology, people have more and more extensive use of mobile terminals, especially mobile phones. However, these mobile terminals often generate electromagnetic radiation during communication, and when the mobile terminal is close to a human body and the electromagnetic radiation power is high, the mobile terminal will cause a certain degree of radiation damage to the human body. Therefore, in order to quantify the influence of the electromagnetic radiation generated by the mobile terminal on the human body, an SAR (Specific Absorption Rate) index is introduced for measuring the radiation degree of the electromagnetic wave, wherein the larger the SAR value is, the more serious the radiation on the human body is.
In order to prevent the problem that the SAR value of the mobile terminal exceeds the standard and brings the electromagnetic radiation exceeding to the user, the prior art generally configures the power control information before the mobile terminal leaves the factory, so that the SAR value corresponding to the maximum transmission power of the mobile terminal does not exceed the SAR standard value. In practical use, the SAR sensor can detect the states of the mobile terminal and the human body to control the power of the antenna, for example, if the mobile terminal is close to the user, the power of the antenna of the mobile terminal is reduced. However, in practical applications, due to inevitable software or hardware abnormality of the SAR sensor, it is difficult to accurately determine the current state, so as to accurately control and adjust the power of the antenna according to the actual situation, thereby causing the risk of exceeding the SAR value.

Fig. 2 shows an exemplary flow of an antenna power control method, which may include the following steps S210 to S230:
step S210, monitoring the state of the electromagnetic wave absorption ratio SAR sensor.
Under the action of an external electromagnetic field, an induced electromagnetic field is usually generated in a human body, and various organs of the human body are lossy media, so that the electromagnetic field in the human body can generate current to absorb and dissipate electromagnetic energy, and the physical process is represented by an SAR index commonly used in biological dosimetry. The meaning of the SAR index is the electromagnetic power absorbed or consumed by human tissue with unit mass, and the unit is W/kg. Generally, before a mobile terminal leaves a factory, a corresponding SAR rule needs to be satisfied, such as CE (European community) certification or FCC (Federal Communications Commission) certification, for example, whether a SAR index meets the rule is tested in a professional laboratory, and when the SAR index passes through various test scenes, the mobile terminal can leave the factory to ensure compliance of the SAR index and avoid the problem that radiation risk is caused to a human body due to excessive SAR.
In actual use, the mobile terminal is configured with the SAR sensor to identify specific parameters in the current scene, so as to determine whether the SAR sensor is close to or far from the human body, that is, whether the mobile terminal is close to or far from the human body, so that the power of the antenna is appropriately backed off or adjusted when the SAR sensor is close to the human body, thereby ensuring the compliance of the SAR index. Taking a single-cell scenario as an example, assuming that a mobile phone a needs to perform CE authentication, when a frequency band LTE B1 on the mobile phone ANT0 is in a full-power state, test values of a head SAR (used for reflecting an SAR parameter used when an ear portion of a mobile terminal is used in a voice call) and a body SAR (used for reflecting an SAR parameter used when a mobile terminal is in contact with a body during use) both satisfy a CE authentication standard requirement of 2.0W/kg, and then ANT0-LTE B1 does not need to perform power backoff. If the head SAR of the frequency band LTE B1 on the ANT0 under the test in the full-power 23dB state exceeds the CE certification standard requirement by 2.0W/kg, a certain power backoff needs to be performed, the power backoff value can be calculated according to a mathematical formula, and a final power backoff value is obtained by combining a certain test error margin, for example, backoff 3dB, so that the frequency band LTE B1 on the ANT0 corresponding to the head SAR can work at 20dB power to meet the requirement of the SAR safety specification.
When the SAR sensor works, a plurality of software modules or hardware components are usually involved, and certain abnormal failure risks, such as software problems of abnormal data transmission, faults and the like, or hardware problems of short circuit or open circuit and the like, exist. When the SAR sensor is in a normal state, the state of approaching or departing can be accurately judged, so that the corresponding power control parameter is called to control the power of the antenna; when the SAR sensor is in the abnormal state, the SAR sensor may face a situation that the SAR sensor makes a misjudgment, and the power control parameter corresponding to the antenna in the current scene cannot be accurately determined, which brings a risk that the SAR exceeds the standard.
Specifically, the present exemplary embodiment may determine the state of the SAR sensor in various ways, for example, when the SAR sensor is close to or far away from the human body, the SAR sensor will correspond to a range of a specific detection parameter (such as Offset value), and if the specific detection parameter exceeds the range, it may be determined that the SAR sensor is in an abnormal state currently; or a reporting mechanism may be configured in the software in advance, and when the software is detected to be abnormal or invalid, an abnormal prompt is reported to the system to determine that the current SAR sensor is in an abnormal state, and the like.
And step S220, when the SAR sensor is judged to be in the abnormal state, acquiring a preset power control parameter corresponding to the abnormal state.
In consideration of the abnormal state, in order to ensure the compliance safety of the SAR index, the power needs to be backed off appropriately, so the preset power control parameter corresponding to the abnormal state may be a power control parameter of a close gear, or a power control parameter of a fail gear preset for software failure. As required, the present exemplary embodiment may further set preset power control parameters corresponding to a plurality of gears for the abnormal state, where the preset power control parameter of each gear has a different power value, so as to correspond to different preset power control parameters in different abnormal states.
In this exemplary embodiment, complete power control parameters including corresponding power control parameters in a normal state and an abnormal state may be configured in advance, so that the corresponding power control parameters can be determined according to the state of the SAR sensor no matter the SAR sensor is in the normal state or the abnormal state. For example, if the SAR sensor is in a normal state, when it is determined that the SAR sensor is close to the human body, the power control parameter of the close gear can be obtained, and when it is determined that the SAR sensor is far from the human body, the power control parameter of the far gear can be obtained; if the SAR sensor is in an abnormal state due to a software problem, preset power control parameters corresponding to the abnormal state, such as power control parameters of a close gear or a failure gear, can be acquired.
It should be noted that, setting of preset power control parameters of the SAR sensor in different states may have different standards, for example, the power control parameter of the approach gear may cause the antenna power to normally and properly back off; when the SAR sensor is far away from a human body, power backoff is generally considered not to be required, but in order to meet the requirements of certain communication scenarios, appropriate power backoff can be set, and specifically, the power backoff can be set by self-definition according to the requirements; the power control parameters of the failure gear can be set by self according to project requirements, for example, in order to ensure that after software fails, the mobile terminal can meet the requirements of the SAR safety specification in different communication scenarios, and more severe power control parameters and the like can be set for the failure gear, which is not specifically limited by the disclosure.
In an exemplary embodiment, the determining that the SAR sensor is in an abnormal state may include:
judging that the SAR sensor receives abnormal information;
wherein the exception information includes: detecting abnormal information or software abnormal information.
The detection value refers to a value of a specific parameter detected by the SAR sensor, for example, an Offset value, and the detection value abnormality information may refer to information that the Offset value is not within a normal range or is within an abnormal range, or the like. The software exception information may refer to information that the information reported by the software is abnormal. The SAR sensor is determined to be in the abnormal state by receiving the detection value abnormal information and the software abnormal information, and the state of the SAR sensor can be monitored from hardware, software and other dimensions, so that the antenna power can be timely and effectively controlled.
In consideration of the effectiveness of the power control parameter, in an exemplary embodiment, the power value corresponding to the preset power control parameter may be set to be lower than the power value corresponding to the conventional power control parameter, where the conventional power control parameter is a power control parameter corresponding to a normal state of the SAR sensor.
In other words, the present exemplary embodiment may set a more severe power control parameter lower than the approaching gear and the far gear as the preset power control parameter corresponding to the abnormal state, so that when the SAR sensor is in the abnormal state, the SAR sensor can perform large-degree backoff on the power of the antenna based on the preset power control parameter, thereby further ensuring the compliance of the SAR.
In an exemplary embodiment, the step S220 may include:
and determining a preset power control parameter corresponding to the abnormal state according to the abnormal state and the current communication scene.
Considering the application requirements of different communication scenarios, for example, in practical applications, the mobile terminal used by the user may be in various communication scenarios such as "cellular," "cellular + bluetooth," "cellular + Wifi (mobile hotspot)," and the like, therefore, the exemplary embodiment may further determine the corresponding preset power control parameter in combination with the current communication scenario after determining the state of the SAR sensor, for example, when the SAR sensor is in an abnormal state, the preset power control parameter of the proximity stage may be called, and the proximity stage may further distinguish the communication scenarios such as "cellular," "cellular +2.4G Wifi +5G Wifi," and the power control parameters thereof generally have differences such as "cellular" - -23dB, "cellular +2.4G Wifi" - -22dB, "cellular +2.4G Wifi +5G Wifi" - -21dB, and the like, if the current communication scenario is "cellular", it may be determined that the preset power control parameter corresponding to the current abnormal state is 23dB, and the like.
It should be noted that, considering that the power control parameter of the fail gear is usually severe, if the power control parameter of the fail gear is called, the process of scene determination may be omitted.
Step S230, controlling the power of the antenna according to the preset power control parameter.
Finally, the preset power control parameter is called to control the power of the antenna, in the exemplary embodiment, the power of the antenna is controlled based on the preset power control parameter corresponding to the abnormal state, the situation that the SAR value exceeds the standard due to the fact that the antenna power is large cannot occur, and the SAR safety standard requirement can be well met.
In summary, in the present exemplary embodiment, the state of the electromagnetic wave absorption ratio SAR sensor is monitored; when the SAR sensor is judged to be in an abnormal state, acquiring a preset power control parameter corresponding to the abnormal state; and controlling the power of the antenna according to the preset power control parameter. On one hand, the exemplary embodiment provides a new antenna power control method, which can timely and effectively adjust the antenna power by monitoring the state of the SAR sensor, and avoid the problem that the SAR sensor does not meet the safety specification due to misjudgment when the SAR sensor is in an abnormal state; on the other hand, the SAR sensor state is monitored, so that the SAR sensor can call the corresponding preset power control parameter to control the power of the antenna when the SAR sensor is in an abnormal state, thereby ensuring that the SAR sensor can accurately adjust the power of the antenna no matter in a normal state or an abnormal state, and being suitable for various application scenes.
In an exemplary embodiment, as shown in fig. 3, the step S220 may include the following steps:
step S310, when the SAR sensor is judged to be in an abnormal state, determining a target power control parameter according to a preset power control parameter corresponding to the abnormal state;
the step S230 may include:
step S320, invoking the target power control parameter to control the power of the antenna.
In this exemplary embodiment, the target power control parameter refers to a parameter finally used for adjusting the antenna power, and may be the same as the preset power control parameter, for example, when it is determined that the SAR sensor is in an abnormal state, the preset power control parameter for obtaining the failure gear is 20dB, and then the preset power control parameter 20dB may be directly used as the target power control parameter.
In addition, the target power control parameter may also be determined based on a preset power control parameter, for example, generally, the SAR Sensor may include a plurality of detection points (e.g., Sensor pads), such as five detection points, each detection point may determine a corresponding detection value for a channel from the SAR Sensor chip, for example, when 5 channels are included, 5 detection values may be detected. Therefore, the exemplary embodiment may detect each channel, determine the corresponding preset power control parameter based on the detected value corresponding to each channel, and determine the target power control parameter according to the preset power control parameter corresponding to each channel. Alternatively, the determination of the target power control parameter may also be combined with the current communication scenario, etc., which is not specifically limited by this disclosure. The power of the antenna is adjusted by presetting the target power control parameter determined by the power control parameter, so that the target power control parameter more meeting the current application requirement is determined to realize the control of the antenna power by combining other factors under the condition of meeting the calling requirement of the power control parameter in an abnormal state, the effectiveness and the accuracy are higher, and higher flexibility and pertinence are realized according to different scene requirements.
In an exemplary embodiment, determining that the SAR sensor receives the abnormal information may include:
and judging that the detection value of the SAR sensor exceeds a normal range.
The SAR sensor may generally include a detection point, the detection point may correspond to a detection channel to the sensor chip, and the SAR sensor may be capable of detecting a capacitance value of the detection channel, where the capacitance value, that is, the detection value in the present exemplary embodiment, may be represented by an Offset value. The detection value can reflect the capacitance change condition of the detection channel influenced by the surrounding environment. Generally, the detection value may be within a normal range, from which it is determined whether the SAR sensor is in a state close to the human body or in a state away from the human body, or the like, and when the detection value is out of the normal range, it may be considered that the SAR sensor is in an abnormal state. For example, assume a normal range of [ a, b ]. When the Offset value exceeds the normal range, namely is smaller than a or larger than b, due to software abnormity or hardware module abnormity and the like of the detection channel, the SAR sensor can be determined to be in an abnormal state.
In an exemplary embodiment, the step S310 may include:
when the detection value of the SAR sensor is judged to be lower than the lower limit value of the normal range, determining a target power control parameter according to a first preset power control parameter;
and when the detection value of the SAR sensor is judged to be higher than the upper limit value of the normal range, determining a target power control parameter according to a second preset power control parameter.
The exemplary embodiment may set the corresponding preset power control parameters in the abnormal states of different gears for different situations where the detection value exceeds the normal range, for example, when the detection value is lower than the lower limit value of the normal range, the first preset power control parameter may be adopted; when the detected value is higher than the upper limit value of the normal range, a second preset power control parameter or the like may be employed. Generally, the power value corresponding to the first predetermined power control parameter may be smaller than the power value corresponding to the second predetermined power control parameter, that is, the first predetermined power control parameter may be set more strictly than the second predetermined power control parameter. In other embodiments, the power value of the second preset power control parameter may also be smaller than the power value corresponding to the first preset power control parameter. Specifically, the configuration of the preset power control parameter and the application scenario may be performed according to actual needs, which is not specifically described in this disclosure.
In an exemplary embodiment, the SAR sensor includes a plurality of detection points; the step S310 may include the following steps:
when at least one abnormal detection point is judged to exist, determining a target power control parameter according to a preset power control parameter corresponding to the abnormal detection point and a conventional power control parameter corresponding to the normal detection point;
the abnormal detection point is a detection point of which the detection value exceeds a normal range, and the normal detection point is a detection point of which the detection value does not exceed the normal range.
The SAR Sensor may generally include a plurality of detection channels, for example, the SAR Sensor may include 5 detection points (Sensor pads), each detection point may correspond to a detection channel, and the SAR Sensor may obtain a detection value, such as an Offset value, corresponding to each channel. In the present exemplary embodiment, it is possible to detect each detection point in turn, that is, detect the Offset value of each channel, and take the detection point corresponding to the channel whose Offset value exceeds the normal range as an abnormal detection point.
In practical application, the mode of determining that the Offset value of the detection channel is abnormal can be selected by user according to project requirements, for example, when the test value of the Offset value of a certain detection channel exceeds a normal range, the detection point corresponding to the detection channel can be determined as an abnormal detection point; or a multi-sampling mode can be adopted, for example, continuous sampling is set for 10 times for the same detection channel, and if the sampling result exceeds 6 times, the detection point corresponding to the detection channel is judged to be an abnormal detection point; or continuous sampling in a preset period, such as continuous sampling for 1 minute, may be set, and the specific detection mode may be set by user as needed, which is not specifically limited in the present disclosure.
In the present exemplary embodiment, when there is at least one abnormal detection point, for example, when the SAR sensor includes 5 detection points, there is one abnormal detection point, the target power control parameter may be determined according to the preset power control parameter corresponding to the abnormal detection point and the normal power control parameter corresponding to the normal detection point, that is, according to the preset power control parameter corresponding to the abnormal detection point and the normal power control parameters corresponding to the other four normal detection points, for example, the power value that is the smallest is taken as the target power control parameter, or a weighted calculation is performed to take the calculated power value as the target power control parameter, so as to determine the target power control parameter.
It should be noted that, in the present exemplary embodiment, the target power control parameter may also be determined according to the preset power control parameter corresponding to the abnormal detection point, the conventional power control parameter corresponding to the normal detection point, and the current communication scenario, so as to ensure that the power control parameter conforming to the current communication scenario can be determined.
In an exemplary embodiment, in the step S310, the determining the target power control parameter according to the preset power control parameter corresponding to the abnormal state may include:
and determining a target power control parameter according to the preset power control parameter corresponding to the abnormal state and the current communication scene.
In this exemplary embodiment, a preset power control parameter corresponding to an abnormal state may be determined, and then, in combination with a current communication scenario, the preset power control parameter may be adjusted to determine a target power control parameter, for example, the preset power control parameter corresponding to a failure state of an SAR sensor is determined to be 20dB, further, in combination with the current communication scenario, in case of a "cellular" communication scenario, the preset power control parameter 20dB may be determined as the target power control parameter, in case of a "cellular + Wifi" communication scenario, the preset power control parameter 20dB may be determined to be backed off to a certain extent, for example, 2dB, that is, the target power control parameter is determined to be 18dB, and the like This is not specifically limited by the present disclosure.
Fig. 4 shows another flowchart of an antenna power control method in the present exemplary embodiment, which may specifically include:
step S410, judging whether the detection value of the SAR sensor exceeds a normal range;
step S420, if the detection value of the SAR sensor does not exceed the normal range, identifying the current SAR sensor to be in a state close to or far away from the human body;
step S430, if the state is close to the human body, acquiring a preset power control parameter corresponding to the approach gear;

step S460, determining a target power control parameter based on the preset power control parameter and the current communication scenario information.
In step S450, the preset power control parameter corresponding to the abnormal state may be a preset power control parameter corresponding to the approaching gear, or may be a preset power control parameter corresponding to the set failure gear. In step S460, the target power control parameter may be determined according to the preset power control parameter and the current communication scenario information, such as a "cellular" communication scenario, a "cellular + Wifi" communication scenario, and the like, and other scenario information such as the operating state of the device, such as the earpiece, and the like, may also be combined, which is not specifically limited by the present disclosure.
In an exemplary embodiment, the determining that the SAR sensor receives the abnormal information may include:
and judging that the information reported by the SAR sensor receiving the software is abnormal.
Considering that a plurality of software modules may be involved in the working process of the SAR sensor, for example, as shown in fig. 5, the SAR sensor chip software 510, the AP (Application Processor) underlying software driver module 520, the modem software module 530, and the like, each software module may include some related processing tasks inside and between modules, which involve a large amount of code, and there may be abnormal problems caused by software bug (computer bug) during the running process, and if these abnormal problems are not managed, the SAR index may also be caused to be in compliance with the safety specification.
Therefore, the exemplary embodiment can determine whether the SAR sensor is in an abnormal state according to whether the information reported between the software modules is abnormal, and when it is determined that the information reported by the SAR sensor is abnormal, it indicates that the SAR sensor is in the abnormal state.
Specifically, in an exemplary embodiment, the determining that the information reported by the SAR sensor is abnormal may include:
judging at least one of the first information, the second information and the third information is abnormal;
the first information is information reported to a driving layer by a hardware layer of the SAR sensor; the second information is information reported to the modem by a driving layer of the SAR sensor; the third information is information obtained by the modem performing scene recognition according to the second information.
Taking three software modules, namely SAR sensor chip software, an AP bottom layer software driver module and a modem software module as an example, as shown in fig. 6, in general, the invoking of the power control parameter of the antenna may include the following steps:
step S610, reporting first information to an AP bottom layer software driving module by SAR sensor chip software;
step S620, the AP bottom layer software driver module judges whether the first information reported by the AP bottom layer software driver module is abnormal according to a preset rule;
when the first information is determined to be effective information, namely the first information is information capable of judging the normal state of the SAR sensor; can execute
Step S630, reporting the processed first information to the modem software module by the AP bottom layer software driver module, namely reporting the second information to the modem software module by the AP bottom layer software driver module;
step S640, the modem software module judges whether the second information is abnormal again;
when the second information is determined to be valid information, execution is performed
Step S650, the modem software module identifies the current scene according to the second information and determines whether the third information is abnormal;
further, executing step S660, the modem software module calls a power control parameter corresponding to the current scene in a normal state;
if the first information is determined to be abnormal information after step S620, or the second information is determined to be abnormal information after step S640, or the third information is determined to be abnormal information after step S650, all the steps are executed
Step S670, a preset power control parameter corresponding to the abnormal state is called.
Specifically, the SAR sensor chip software can report the close or far state information determined according to the detection value of each detection channel to the AP bottom layer software driver module so that the AP bottom layer software driver module can determine whether the state information is valid information, wherein the state information can be represented by binary identifiers, for example, by "00" and "01", respectively, the current SAR sensor is in a state close to a human body or in a state far from the human body, and when the SAR sensor chip software reports information of "10" or "11", an abnormality can be reported to the AP bottom layer software driver module. The second information is information reported to the modem by the driver layer of the SAR sensor, that is, information reported to the modem software module again after the AP bottom layer software driver module determines the first information, and the modem software module determines whether the information is valid again. The third information is information indicating whether the judgment information of the scenario related to the modem software module is valid, for example, whether the current communication scenario can be accurately and normally determined, so as to invoke the relevant power control parameter in combination with the current communication scenario. When the SAR sensor works normally, the flow judgment and the calling of the power control value are needed to be carried out once again every time the SAR sensor chip software is triggered again, and the power control parameters of the corresponding scene can be accurately called to control the antenna power through the steps. Therefore, in the above flow, when any one of the first information, the second information, and the third information is abnormal, it may be determined that the current problem of software abnormality occurs, and the power control parameter corresponding to the scene in the normal state and the preset power control parameter corresponding to the abnormal state may not be called. In the exemplary embodiment, a multi-level logic judgment is not needed, and only by judging whether the information in any one stage of the first information, the second information and the third information is abnormal, whether the current software has an abnormal problem can be determined, and whether the SAR sensor is in an abnormal state can be further determined.
It should be noted that, in the present exemplary embodiment, once the abnormal information occurs, the problem of software abnormality occurs, and therefore, the preset power control parameter corresponding to the abnormal state may be set more strictly, for example, the preset power control parameter of the failure gear may be directly called, or the power control parameter with a lower power value may be preset, and the disclosure does not specifically limit this.
