Description

Terminal power saving method based on wireless local area network connection and terminal

Technical Field

The present application relates to the field of communications technologies, and in particular, to a power saving method for a terminal based on wlan connection and a terminal.

Background

At present, when a terminal is connected with a wireless fidelity (WiFi) or a voice over Wi-Fi (VoWiFi) based WiFi connection state, there are various high power consumption behaviors, for example, when the terminal is connected with the WiFi or the VoWiFi, an out of service (OOS) network searching mode is still performed, and when the terminal is connected with the WiFi or the VoWiFi, for example, the terminal still performs measurement behaviors of the same frequency, different systems and the like, and when the terminal is connected with the WiFi or the VoWiFi, the terminal still performs cell reselection, redirection and the like.

Disclosure of Invention

The embodiment of the application provides a terminal power saving method based on wireless local area network connection and a terminal, so as to reduce power consumption generated by interaction between the terminal and a mobile communication network under the condition of connecting the wireless local area network.

In a first aspect, the present application provides a power saving method for a terminal based on wlan connection, where the method includes: after establishing the wireless local area network connection, when the terminal meets the condition of triggering the high power consumption behavior under the current mobile communication network environment, the terminal determines the state of the wireless local area network connection, and when the wireless local area network connection is in a normal connection state, the terminal limits or does not initiate the high power consumption behavior. Wherein the high power consumption behavior comprises one or more of: the method comprises the steps of a non-service network searching process, a measuring behavior, a cell reselection process, a redirection process and a registration process initiated to a second location area after receiving a rejection response of a network where a first location area is located.

Based on the scheme, when the condition that the terminal triggers the high power consumption behavior is met in the mobile communication network environment where the terminal is located at present, the terminal is in a normal connection state in the wireless local area network connection, which indicates that data transmission can be normally performed through the wireless local area network connection, and at this time, the terminal can stop the high power consumption behavior.

In a possible design, the high power consumption behavior may include a non-service network searching process, and the terminal may extend a time interval between two adjacent historical frequency band searches in the non-service network searching process when the wlan connection is in a normal connection state. The total duration of the non-service network searching process is fixed, the time interval of two adjacent historical frequency band searches is prolonged, the number of historical frequency band searches can be reduced, and therefore redundant power consumption generated by the terminal due to unlimited initiation of the non-service network searching process can be reduced.

In one possible design, the high power consumption behavior may include a measurement behavior of the terminal with respect to the network, and the terminal may not initiate the measurement behavior of any cell other than the cell where the terminal currently resides when the wlan connection is in a normal connection state. Therefore, the signal quality of the current resident cell of the terminal can be monitored, and the redundant power consumption caused by measurement is reduced, so that the effect of saving power is achieved.

In one possible design, the high power consumption behavior may include a cell reselection procedure, and the terminal may not initiate the cell reselection procedure when the wlan connection is in a normal connection state. Therefore, redundant power consumption caused by the cell reselection process can be reduced, and the effect of power saving is achieved.

In one possible design, the high power consumption behavior may include a redirection procedure that is not initiated by the terminal when the wlan connection is in a normal connection state. Therefore, redundant power consumption caused by the redirection process can be reduced, and the effect of power saving is achieved.

In a possible design, the high power consumption behavior may further include initiating a registration procedure to the second location area after receiving a rejection response of the network where the first location area is located, and the terminal may not initiate the registration procedure to the second location area when the wlan connection is in a normal connection state. Therefore, redundant power consumption caused by initiating the registration request to the second location area can be reduced, and the effect of saving power consumption can be achieved.

In one possible design, the terminal may further determine a motion state of the terminal and/or a signal state of a camping cell of the terminal before limiting or not initiating the high power consumption behavior when the wlan connection is in a normal connection state. The method comprises the steps that the terminal determines that a motion state is in a first state and/or a signal state meets a first condition, and when the wireless local area network connection is in a normal connection state, high power consumption behaviors are limited or not initiated, wherein the first state can be a static state or a motion state with a moving distance smaller than a first threshold value; the first condition may include: the reference signal received power RSRP is higher than a first threshold value, the reference signal received quality RSRQ is higher than a second threshold value, and the signal to interference plus noise ratio SINR is higher than a third threshold value.

Through the design, the signal state of the resident cell of the terminal meets the first condition, which indicates that the signal state of the resident cell of the terminal is good, the terminal can normally talk with the terminal without high-power-consumption behavior, the motion state of the terminal is the first state, which indicates that the terminal does not move or moves in a small range, and the service provided by the resident cell of the terminal can be continuously obtained, the terminal meets the first condition when the motion state is in the first state and/or the signal state of the resident cell of the terminal, and when the wireless local area network connection is in a normal connection state, the high-power-consumption behavior is not initiated, so that the redundant power consumption caused by the high-power-consumption behavior can be reduced under the condition that the resident cell of the terminal where the terminal currently resides guarantees normal communication, and the power saving effect can be achieved.

In a second aspect, the present application provides a terminal power saving device based on a wireless local area network connection, which may be a device used in a communication system, and may also be a chip or a chipset used in a device in the communication system, where the device used in the communication system may be a terminal. The apparatus may include a processing unit and a transceiver unit. When the apparatus is an apparatus for a communication system, the processing unit may be a processor, and the transceiving unit may be a transceiver; the apparatus may further include a storage unit, which may be a memory; the storage unit is configured to store instructions, and the processing unit executes the instructions stored in the storage unit, so as to enable the terminal to perform the corresponding functions in the first aspect. When the apparatus is a chip or a chipset within a network device, the processing unit may be a processor, and the transceiving unit may be an input/output interface, a pin, a circuit, or the like; the processing unit executes the instructions stored by the storage unit to make the terminal execute the corresponding functions in the first aspect. The memory unit may be a memory unit (e.g., register, cache, etc.) within the chip or chipset, or a memory unit (e.g., read only memory, random access memory, etc.) external to the chip or chipset within a device for a communication system.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

The embodiment of the application can be applied to various mobile communication systems, such as: new Radio (NR) systems, global system for mobile communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, advanced long term evolution (LTE-a) systems, evolved Long Term Evolution (LTE) systems, future 5G communication systems, and other communication systems, and in particular, are not limited herein.

Please refer to fig. 1a, which is a schematic diagram of a communication system according to the present application. The communication system may include an access network device, a wireless access point, and a terminal.

As shown in fig. 1a, the communication system includes an access network device 100, a terminal 200, and a wireless Access Point (AP) 300. The connection mode between the access network device 100 and the terminal 200 may be a wireless connection, and the connection mode between the terminal 200 and the wireless access point 300 is a wireless local area network connection. The wireless local area network connection can comprise two types of WiFi connection and VoWiFi connection, wherein VoWiFi is an intelligent terminal with VoWiFi capability used by a user, and voice and video calls can be carried out in a traditional dialing mode under the WiFi environment.

The access network device 100 may be an evolved Node B (eNB or e-NodeB) in LTE, a new radio controller (NR controller), a enode B (gNB) in 5G system, a centralized network element (centralized unit), a new radio base station, a radio remote module, a micro base station, a relay (relay), a distributed network element (distributed unit), a reception point (TRP) or a Transmission Point (TP), or any other radio access device, but the embodiment of the present invention is not limited thereto. The access network device may cover 1 or more cells.

The terminal 200 may also be referred to as a terminal equipment (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like. Specifically, the terminal may be a mobile phone (mobile phone), a tablet (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like, which are not limited thereto. For example, the terminal of the embodiment of the present application includes, but is not limited to, a mount

Or other operating system.

The wireless access point 300 may be a router or other terminal or electronic device with WiFi access functionality.

In this embodiment, the terminal 200 may camp in a certain cell under the access network device 100, and then camp in the cell to provide a service for the terminal 200, that is, a serving cell referred to below. After the camping cell is camped, the terminal 200 may also perform measurements on the camping cell and the neighboring cells to monitor the signal quality of the camping cell and the neighboring cells. When the resident cell meets the reselection condition, cell reselection may also be performed to reselect to an optimal cell to provide a service for the terminal 200. When the terminal is in a connected state and receives a redirection instruction sent by access network equipment, the terminal executes a redirection process, wherein one process is that a network sends a measurement control message, the terminal measures signals of candidate cells and reports a measurement report to the network, and the network sends the redirection instruction; the other is blind redirection, which is that a network directly issues a redirection instruction, and a terminal directly executes redirection unconditionally.

After the terminal 200 establishes the wlan connection with the wireless access point 300, data transmission between the terminal and other devices may be performed based on the wlan connection, and the above-mentioned measurement behavior of the terminal with respect to the network, cell reselection process, redirection process, and OOS network searching process, and the behavior of initiating a registration process to the second location area after receiving a response rejection from the network where the first location area is located may also be performed continuously and indefinitely, which may result in unnecessary power consumption.

Please refer to fig. 1b, which is a schematic structural diagram of a terminal applicable to the present application.

It should be understood that the illustrated terminal 200 is merely an example, and that the terminal 200 may have more or fewer components than shown in the figures, may combine two or more components, or may have a different configuration of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

The terminal 200 may include one or more processors 201, memory 202, Radio Frequency (RF) circuitry 203, audio circuitry 240, speaker 241, microphone 242, touch screen 250, one or more sensors 206, WiFi module 207, peripherals interface 308, and power module 309. These components may communicate over one or more communication buses or signal lines (not shown in FIG. 1 b). Those skilled in the art will appreciate that the hardware configuration shown in fig. 1b does not constitute a limitation of terminal 200, and terminal 200 may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes the various components of terminal 200 in more detail:

the processor 201 is a control center of the terminal 200, connects various parts of the terminal 200 using various interfaces and lines, and performs various functions of the terminal 200 by executing or executing program instructions stored in the memory 202 and calling data stored in the memory 202. In some embodiments, the processor 201 may include one or more processing units. The processor 201 may also integrate an Application Processor (AP) and a modem processor. The application processor mainly processes an operating system, a user interface, application programs and the like, and the modem processor mainly processes wireless communication. It will be appreciated that the modem processor described above may not be integrated into the processor 201. In some other embodiments of the present application, the processor 201 may further include a fingerprint verification chip for verifying the acquired fingerprint.

The memory 202 is used to store programs and data. The memory 202 mainly includes a program storage area and a data storage area. Wherein the program storage area may store an operating system (e.g., a virtual machine operating system)

An operating system,

An operating system, etc.), application programs required for at least one function (such as a sound playing function, an image playing function, etc.). The data storage area may store data (such as audio data, a phonebook, etc.) created when the user uses the terminal 200.

The RF circuitry 203 may be used for receiving and transmitting wireless signals during the transmission and reception of information or during a call. Specifically, the RF circuit 203 may receive downlink data of the base station and then process the downlink data to the processor 201. In addition, the RF circuit 203 may also transmit uplink data to the base station. In general, the RF circuitry 203 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like. In addition, the RF circuitry 203 may also enable communication with other devices via wireless communication. The wireless communication may use any communication standard or protocol including, but not limited to, global system for mobile communications, general packet radio service, code division multiple access, wideband code division multiple access, long term evolution, email, short message service, and the like.

The audio circuitry 240, speaker 241, microphone 242 may provide an audio interface between a user and the terminal 200. The audio circuit 240 may transmit the electrical signal converted from the received audio data to the speaker 241, and convert the electrical signal into a sound signal by the speaker 241 for output; on the other hand, the microphone 242 converts the collected sound signals into electrical signals, which are received by the audio circuit 240 and converted into audio data, which are then output to the RF circuit 203 for transmission to, for example, a cell phone, or to the memory 202 for further processing.

Touch screen 250 may include a touch sensitive surface 251 and a display 252. Among other things, touch sensitive surface 251 (e.g., a touch panel) can capture touch events on or near the touch sensitive surface 251 by a user of terminal 200 (e.g., user manipulation of a finger, stylus, or any other suitable object on or near touch sensitive surface 251) and transmit captured touch information to another device, such as processor 201. Among other things, a touch event of a user near the touch-sensitive surface 251 may be referred to as a hover touch. Hover touch may refer to a user not having to directly contact the touchpad in order to select, move, or drag a target (e.g., an application icon, etc.), but rather only having to be located near the electronic device in order to perform a desired function. In the context of a hover touch application, the terms "touch," "contact," and the like do not imply a contact that is used to directly contact the touch screen 250, but rather a contact that is near or in proximity thereto. The touch-sensitive surface 251 capable of floating touch control can be implemented by using capacitance, infrared light sensing, ultrasonic waves and the like.

The touch sensitive surface 251 may comprise two parts, a touch detection means and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 201, and the touch controller can also receive and execute instructions sent by the processor 201. In addition, the touch-sensitive surface 251 may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves.

A display (also referred to as a display screen) 252 may be used to display information entered by or provided to the user, as well as various menus for terminal 200. The display 252 may include both a display controller and a display device. Wherein the display controller is used for receiving signals or data sent by the processor 201 to drive the display device to display a corresponding interface. For example, the display device may be configured by an Active Matrix Organic Light Emitting Diode (AMOLED).

It should be appreciated that the touch sensitive surface 251 may overlie the display 252, and that when a touch event is detected on or near the touch sensitive surface 251, it is communicated to the processor 201 to determine the type of touch event, and the processor 201 may then provide a corresponding visual output on the display 252 in accordance with the type of touch event. Although in FIG. 1b touch-sensitive surface 251 and display 252 are shown as two separate components to implement the input and output functions of terminal 200, in some embodiments touch-sensitive surface 251 and display 252 may be integrated to implement the input and output functions of terminal 200. It is understood that the touch screen 250 is formed by stacking multiple layers of materials, and only the touch-sensitive surface (layer) and the display (layer) are shown in the embodiment of the present application, and the description of the other layers is omitted in the embodiment of the present application. In addition, in some other embodiments of the present application, the touch-sensitive surface 251 may be covered on the display 252, and the size of the touch-sensitive surface 251 is larger than that of the display 252, so that the display 252 is completely covered under the touch-sensitive surface 251, or the touch-sensitive surface 251 may be configured on the front surface of the terminal 200 in a full-panel manner, that is, all touches of the user on the front surface of the terminal 200 can be sensed by the mobile phone, so that a full-touch experience on the front surface of the mobile phone can be achieved. In other embodiments, the touch-sensitive surface 251 is disposed on the front surface of the terminal 200 in a full-panel manner, and the display 252 may be disposed on the front surface of the terminal 200 in a full-panel manner, so that a frameless structure can be implemented on the front surface of the mobile phone. In some other embodiments of the present application, the touch screen 250 may further include a series of pressure sensor arrays that may enable the cell phone to sense the pressure applied to the touch screen 250 by the touch event.

One or more sensors 206, such as light sensors, motion sensors, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display of the touch screen 250 according to the brightness of ambient light, and a proximity sensor that turns off the power of the display when the terminal 200 moves to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), and the like.

In some embodiments of the present application, the sensor 206 may also include a fingerprint sensor. For example, the fingerprint sensor may be disposed on the rear side of the terminal 200 (e.g., below the rear camera), or the fingerprint sensor may be disposed on the front side of the terminal 200 (e.g., below the touch screen 250). In addition, the fingerprint recognition function may also be implemented by configuring a fingerprint sensor in the touch screen 250, that is, the fingerprint sensor may be integrated with the touch screen 250 to implement the fingerprint recognition function of the terminal 200. In this case, the fingerprint sensor may be disposed in the touch screen 250, may be a part of the touch screen 250, or may be otherwise disposed in the touch screen 250. Additionally, the fingerprint sensor may be implemented as a full panel fingerprint sensor, and thus, the touch screen 250 may be considered as a panel that can be used for fingerprint acquisition at any location. In some embodiments, the fingerprint sensor may process the captured fingerprint (e.g., verify the captured fingerprint), and send the fingerprint processing result (e.g., whether the fingerprint passes the verification) to the processor 201, and the processor 201 performs corresponding processing according to the fingerprint processing result. In other embodiments, the fingerprint sensor may also send the captured fingerprint to the processor 201 for processing (e.g., fingerprint verification, etc.) by the processor 201. The fingerprint sensor in embodiments of the present application may employ any type of sensing technology including, but not limited to, optical, capacitive, piezoelectric, or ultrasonic sensing technologies, among others. In addition, the terminal 200 may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which are not described in detail herein.

A WiFi module 207 for providing the terminal 200 with network access complying with WiFi-related standard protocols. The terminal 200 can access to a wireless Access Point (AP) through the WiFi module 207. In addition, the terminal 200 including the WiFi module 207 may also serve as a wireless access point, and the terminal 200 opens a WiFi hotspot to provide WiFi network access to other terminals. It is understood that the WiFi related standard protocols may include IEEE802.11ac, IEEE802.11b, IEEE802.11g/a, and/or IEEE802.11n, among others.

The peripheral interface 208 is used to provide various interfaces for external input/output devices (e.g., keyboard, mouse, external display, external memory, SIM card, etc.). For example, the mouse is connected with the universal serial bus interface, and the user identification module card is connected with a user identification module card provided by an operator through metal contacts on a user identification module card slot. Peripheral interface 208 may be used to couple the aforementioned external input/output peripherals to processor 201 and memory 203.

The terminal 200 may further include a power module 209 (e.g., a battery and a power management chip) for supplying power to various components, and the battery may be logically connected to the processor 201 through the power management chip, so as to implement functions of managing charging, discharging, and power consumption through the power module 209.

Although not shown in fig. 1b, the terminal 200 may further include a bluetooth module, a positioning module, a camera (e.g., a front camera and a rear camera), a flash, a micro-projector, a Near Field Communication (NFC) module, and the like, which are not described in detail herein.

At present, a terminal has various high power consumption behaviors under the condition of connecting a wireless local area network (WiFi or VoWiFi), and the high power consumption behaviors are specifically described below.

In the first situation, when the terminal is connected to a wireless local area network (WiFi or VoWiFi), a high power consumption behavior of an out of service (OOS) network searching process still occurs.

The OOS network search refers to a network search process performed at intervals by the UE after a network search failure triggered by network loss after startup network search failure or successful registration is performed, and the process may be divided into two stages, where an interval duration between two adjacent network searches in each stage is configurable by a non-volatile memory (NVRAM) in the terminal, where the NVRAM may also be referred to as NV, and for example, an interval duration in the first stage is configured to be 1s, and an interval duration in the second stage is configured to be 10 s.

Fig. 2 is a schematic diagram of an OOS network searching process applicable to the present application.

As shown in fig. 2, the network searching process in one stage is as follows: the first selected type of the search network is history band (history band) search (indicated by H in fig. 2), when the history band search is finished each time, a timer is started, the timing duration of the timer is T1, and when the available timer is overtime, the next history band search is performed, that is, the time interval between two adjacent history band searches is T1.

After the NH historical band searches, the available is timed out again, the selected search type is a preferred frequency band (prefband) search (denoted by P in fig. 2), and in consideration of the fact that the historical band search time is short, a round of historical band search is performed before the prefband search is performed.

After NP Pref band searches, NH store band searches are performed. One Full band search was performed after NH history band searches. Similar to the Pref band search, a history band search is still performed before the Full band search.

After NH times of Full band search, or the available timer is overtime, the network searching process of the next stage is entered.

When the terminal is connected to a wireless local area network (WiFi or VoWiFi), the Modem (Modem) of the terminal still performs the OOS network searching process, which results in unnecessary high power consumption behavior of the terminal.

In the second situation, when the terminal is connected to a wireless local area network (WiFi or VoWiFi), high power consumption behaviors such as common-frequency measurement, different-system measurement and the like are still performed.

After a general terminal selects a serving cell and performs camping, in order to ensure stability and better performance of network service, the terminal monitors signal quality of the serving cell and an adjacent cell in an idle mode, that is, starts common-frequency measurement, different-system measurement and the like, so as to select an optimal cell from candidate cells for cell reselection and provide service for the terminal.

The principle that the terminal starts the same-frequency measurement is as follows: if the serving cell of the terminal meets the conditions of cell selection reception level (Srxlev) > co-frequency measurement starting power threshold (SIntraSearchP) and cell selection reception signal quality (Squal) > co-frequency measurement starting quality threshold (SIntraSearchQ), the co-frequency measurement can be started, and the co-frequency measurement needs to be started under other conditions.

The principle of starting the different-frequency different-system measurement by the terminal is as follows: for the pilot frequency cell with the priority higher than the frequency of the current terminal, the terminal starts high-priority pilot frequency measurement, and for the pilot frequency cell with the priority equal to or lower than the frequency of the current terminal: if the serving cell of the terminal meets the condition (Srxlev) > different-frequency different-system measurement starting power threshold (snoninternarch p) and the cell selection received signal quality (Squal) > different-frequency different-system measurement starting quality threshold (snoninternarchq), the different-frequency different-system measurement may not be started, and the terminal needs to start the different-frequency different-system measurement under other conditions.

When the user data is transmitted based on the wlan connection, the Modem of the terminal still has a measurement behavior, resulting in excessive power consumption.

In case three, the terminal is in a state of connecting to a wireless local area network (WiFi or VoWiFi), and still performs a high power consumption behavior of cell reselection.

Cell reselection (cell reselection) refers to a process in which a terminal selects an optimal cell to provide a service signal by monitoring signal qualities of a neighboring cell and a current serving cell in an idle mode. When the signal quality and level of the neighboring cell satisfy the S criterion and satisfy a certain reselection decision criterion, the terminal will access the neighboring cell for camping, and the specific content of the S criterion is the prior art and is not described herein again. The condition for the terminal to initiate the cell reselection request may be any one or more of the following conditions:

condition 1, the current serving cell does not meet the camping condition, i.e. the current serving cell cannot meet the service level of the S-criteria.

Conditional 2, determining that the serving cell is barred according to a cell barred description in a System Information Block (SIB) 3, wherein the SIB3 mainly contains parameters for cell selection and reselection.

And 3, finding a cell more suitable for residing through measurement, wherein when the terminal is in an idle mode, two measurement modes are adopted: the measurement can be divided into periodicity and triggering.

In one example, when the serving cell meets the start principle of the intra-frequency measurement, the intra-frequency measurement is started, and it is determined according to the measurement result that the signal measurement Rn of the neighboring cell is greater than the signal quality Rs of the serving cell, the cell reselection may be performed. The starting principle of the common-frequency measurement refers to the related description in the second scenario, and is not described herein again.

In another example, when the serving cell meets the start principle of the intra-frequency measurement, the inter-frequency measurement or the inter-system measurement is started, and whether to perform cell reselection is determined according to the measurement result, and the start principle of the inter-frequency measurement or the inter-system measurement is referred to the related description in the above second scenario, and is not described herein again.

When the terminal reselects to the neighboring cell with high priority, the terminal can reselect to the neighboring cell with high priority regardless of the signal quality of the serving cell as long as the signal quality of the neighboring cell with high priority exceeds a certain threshold. When reselecting to a neighboring cell with low priority, the signal quality of the serving cell needs to be lower than a certain threshold, and the signal quality of the neighboring cell with low priority is higher than a certain threshold to perform reselection.

When the user data is transmitted by connecting to the wireless local area network, the Modem still has a cell reselection behavior, resulting in redundant power consumption.

In case four, the terminal still performs redirection high power consumption behavior when connected to a wireless local area network (WiFi or VoWiFi).

Before initiating a redirection process, a network side may issue a Radio Resource Control (RRC) release message to a terminal, where the RRC release message carries a target access technology and a frequency point for redirection. After the terminal receives a redirection instruction from the network side, the GRR in the terminal may instruct a higher layer (RRC layer) to initiate a redirection procedure, the higher layer will complete a suspension process, and switch the master mode to a T mode, for example, switch from 2G to 3G network, for example, switch from 3G to 4G network, and the network after the RRC switching searches for a cell successfully. After the system message is successfully received, the GRR is successfully returned and redirected.

When the user data is transmitted based on the WiFi connection, the Modem still has a redirection behavior, resulting in excessive power consumption.

In case that the terminal is connected to a wireless local area network (WiFi or VoWiFi), the terminal initiates high power consumption behaviors of registration processes such as Location Area Update (LAU), authentication, attach (attach), Tracking Area Update (TAU) and the like to a plurality of Location Areas (LA) when the terminal is under-consumed.

Under the condition of connecting WiFi or VoWiFi, when a terminal initiates registration procedures such as LAU, authentication, attach, TAU and the like to a current LA, due to a UE defaulting, a network side replies a rejection message, where a cause value carried in the rejection message is #15(No capable cells in tracking area), the terminal still initiates registration procedures such as LAU, authentication, attach, TAU and the like to other LAs, but the terminal is also rejected, so that initiating actions such as LAU, authentication, attach, TAU and the like to other LAs also causes redundant power consumption.

In any of the above five cases, the high power consumption behavior of the terminal in the WiFi or VoWiFi connected state may result in a serious power consumption of the terminal, a short standby time, and an adverse effect on the user.

In order to reduce power consumption of a terminal when the terminal is connected with WiFi or VoWiFi, embodiments of the present application provide a terminal power saving method based on wlan connection. Referring to fig. 3, a schematic flowchart of a power saving method for a terminal based on wlan connection according to an embodiment of the present disclosure is shown. As shown in fig. 3, the method flow includes the following steps:

step 301, after establishing the wlan connection, when the terminal meets the condition of triggering the high power consumption behavior in the current mobile communication network environment, the terminal determines the wlan connection status.

Here, the wireless local area network connection may include a WiFi connection or a VoWiFi connection. The state of the wlan connection includes a normal connection state or a disconnection state.

Wherein the high power consumption behavior may include, but is not limited to, one or more of: the method comprises the steps of a non-service network searching process, a measuring behavior, a cell reselection process, a redirection process, and a registration process initiated to a second location area after a rejection response of a network where a first location area is located is received, wherein the second location area can be any location area except the first location area.

Step 302, when the wireless local area network connection is in a normal connection state, the terminal limits or does not initiate a high power consumption behavior.

In the embodiment of the application, when the terminal meets the condition of triggering the high power consumption behavior in the current mobile communication network environment, the terminal is in the normal connection state in the wireless local area network connection, which indicates that data transmission can be normally performed through the wireless local area network connection, and at this time, the terminal can stop the high power consumption behavior.

In this embodiment, there are various implementations that may implement the limitation or not initiate the high power consumption behavior in step 302.

In a manner that the high power consumption behavior can be limited, the high power consumption behavior may include a non-service network searching process, and the terminal may extend a time interval between two adjacent historical frequency band searches in the non-service network searching process when the wireless local area network connection is in a normal connection state. The total duration of the non-service network searching process is fixed, the time interval of two adjacent historical frequency band searches is prolonged, the number of historical frequency band searches can be reduced, and therefore redundant power consumption generated by the terminal due to unlimited initiation of the non-service network searching process can be reduced.

In a mode of realizing no initiation of high power consumption behavior, the high power consumption behavior can comprise a non-service network searching process, and the terminal can also not initiate the non-service network searching process when the wireless local area network connection is in a normal connection state, so that redundant power consumption generated by the terminal due to initiation of the non-service network searching process can be reduced.

In another way that the high power consumption behavior may not be initiated, the high power consumption behavior may include a measurement behavior of the terminal with respect to the network, and the terminal may not initiate a measurement behavior of any cell other than the cell where the terminal currently resides when the wlan connection is in a normal connection state. Therefore, the signal quality of the current resident cell of the terminal where the terminal resides can be monitored, and the redundant power consumption caused by measurement is reduced, so that the effect of saving power is achieved.

In another way that the high power consumption behavior may not be initiated, the high power consumption behavior may include a cell reselection process, and the terminal may not initiate the cell reselection process when the wlan connection is in a normal connection state. Therefore, redundant power consumption caused by the cell reselection process can be reduced, and the effect of saving power is achieved.

In another way, the high power consumption behavior may include a redirection procedure, and the terminal does not initiate the redirection procedure when the wlan connection is in a normal connection state. Therefore, redundant power consumption caused by the redirection process can be reduced, and the effect of saving power is achieved.

In another mode that may implement not initiating the high power consumption behavior, the high power consumption behavior may further include initiating a registration procedure to the second location area after receiving a rejection response of the network where the first location area is located, and the terminal may not initiate the registration procedure to the second location area when the wlan connection is in a normal connection state. Therefore, redundant power consumption caused by initiating registration requests to other location areas can be reduced, and the effect of saving power consumption can be achieved.

Generally speaking, when a terminal resides in a cell with a good signal state, in order to ensure that a call can be normally performed, even if the signal state of the current resident cell of the terminal is good, that is, the current resident cell of the terminal has the ability to ensure that the call is normal, the terminal may continue to perform the actions of the terminal, such as a measurement action with respect to the network, a cell reselection procedure, a redirection procedure, an OOS network searching procedure, and a registration procedure initiated to a second location area after receiving a rejection response from the network where the first location area is located, which may cause the terminal to interact with the mobile communication network and generate unnecessary power consumption when establishing a communication connection with the wireless local area network and the mobile communication network.

Based on any of the above embodiments, in a possible implementation manner, when the wlan connection is in a normal connection state, before limiting or not initiating the high power consumption behavior, the terminal may further determine a motion state of the terminal and/or a signal state of a current cell where the terminal resides.

Specifically, the terminal may determine a motion state of the terminal and a connection state of the wireless local area network when a condition for triggering a high power consumption behavior is satisfied in a current mobile communication network environment, may also determine a signal state of a current resident cell of the terminal and a connection state of the wireless local area network, and may also determine the motion state of the terminal, the signal state of the current resident cell of the terminal and the connection state of the wireless local area network.

When the motion state of the terminal is in a first state and/or the signal state of the resident cell of the terminal currently meets a first condition, and the wireless local area network connection is in a normal connection state, the high power consumption behavior is limited or not initiated, wherein the first state may be a static state or a motion state in which the moving distance is smaller than a first threshold, and the first condition may include: the reference signal received power RSRP is higher than a first threshold value, the reference signal received quality RSRQ is higher than a second threshold value and the signal to interference plus noise ratio SINR is higher than a third threshold value. Specific values of the first threshold, the second threshold, and the third threshold are not limited herein, and for example, the first threshold may be-115 dbm, the second threshold may be-15, and the third threshold may be 0.

For example, the high power consumption behavior may include a no-service network searching process, and the terminal may limit or not initiate the no-service network searching process when the motion state is in the first state and the wireless local area network connection is in the normal connection state.

For example, the high power consumption behavior may include any one of a measurement behavior of the terminal with respect to the network, a cell reselection procedure, a redirection procedure, and a registration procedure initiated by the terminal to the second location area after receiving a rejection response of the network where the first location area is located, and the terminal may limit or not initiate the high power consumption behavior when the motion state is in the first state, and the wireless local area network connection is in a normal connection state.

Wherein, the signal state of the current resident cell of the terminal meets the first condition, which indicates that the signal state of the current resident cell of the terminal is good, the terminal can not need to carry out normal conversation of the terminal which can be ensured by high power consumption behavior, the motion state of the terminal is the first state, which indicates that the terminal does not move or moves in a small range, and can continue to obtain the service provided by the current resident cell of the terminal, the terminal limits or does not initiate the high power consumption behavior when the motion state of the terminal is in the first state and/or the signal of the current resident cell of the terminal meets the first condition and the connection of the wireless local area network is in a normal connection state, and can reduce the redundant power consumption caused by the high power consumption behavior generated by interaction with the mobile communication network under the condition that the current resident cell of the terminal has the capacity of ensuring normal communication, the effect of saving electricity is achieved.

The following describes, with reference to specific examples, solutions for providing high power consumption behavior for the above-mentioned several scenarios.

For example, for the high power consumption behavior in the first scenario, when the terminal is in a WiFi (or VoWiFi) connection state, if the terminal meets a condition for triggering an OOS network searching process, a time interval between two adjacent historical frequency band searches in an out-of-service network searching process may be extended (or lengthened) when the OOS network searching process is initiated, and for example, the time interval between history band searches may be lengthened by 3 times, so as to achieve the purpose of saving power consumption.

Referring to fig. 4, a schematic flow chart of a power saving method for a terminal based on wlan connection according to the present invention is shown. As shown in fig. 4, the method flow includes the following steps:

in step 401, when the WiFi (or VoWiFi) connection state of the terminal changes (for example, changes from a normal connection state to a disconnection state, or changes from a disconnection state to a normal connection state), the application processor AP of the terminal issues a message to the non-access stratum Modem NAS of the Modem to notify the Modem NAS module that the WiFi (or VoWiFi) connection state of the terminal currently changes.

In step 402, the Modem NAS saves the current WiFi (or VoWiFi) connection status of the terminal as a global variable for other components to access.

In step 403, when the signal of the base station is lost for some reason. The reason may be, for example, that the terminal enters a no-signal coverage area.

In step 404, the terminal enters an OOS network searching state due to long-time signal loss.

In step 405, the NAS determines whether to lengthen the time interval between two adjacent historical band (history band) searches according to the WiFi (or VoWiFi) connection state of the current terminal.

For example, when the terminal is currently in a state of disconnecting the WiFi (or VoWiFi) connection, the network searching interval T1 of the conventional OOS network searching mode is maintained so as to search for the mobile communication network as soon as possible. When the terminal is in a normal WiFi (or VoWiFi) connection state, the time interval between two consecutive history band searches in each network searching stage is lengthened, for example, the time interval is lengthened to 3 times of the conventional OOS network searching mode, that is, 3T 1. Therefore, the state of the wireless local area network connection and the OOS network searching state of the Modem are combined with each other, and two chip states can be combined to form a user power consumption experience package navigation.

By taking the example, when the terminal is connected with WiFi (or VoWiFi), the time interval between two adjacent history band searches in each network searching stage of the OOS network searching process is lengthened, taking a stage as an example, the total time of network searching in this stage is fixed, and the time interval of history band searches in the stage is lengthened, so that the number of history band searches can be reduced, and the effect of saving power consumption can be achieved.

Example two, for the high power consumption behavior of the above case two, when the terminal is in the WiFi (or VoWiFi) connection state, the terminal camps on the current cell for more than a certain period of time (e.g. 1 minute), during which the camped cell does not change, and the Reference Signal Receiving Power (RSRP), the Reference Signal Receiving Quality (RSRQ), the signal to interference plus noise ratio (SINR) of the current camped cell are better than the fixed private threshold, and the signal of the camped cell reaches the measurement threshold, the terminal stops all the measurement behaviors of any cell except the current camped cell, so as to achieve the purpose of saving power consumption.

Referring to fig. 5, a schematic flow chart of a power saving method for a terminal based on wlan connection according to the present invention is shown. As shown in fig. 5, the method flow includes the following steps:

in step 501, when the WiFi (or VoWiFi) connection status of the terminal changes (for example, changes from a normal connection status to a disconnection status, or changes from a disconnection status to a normal connection status), the application processor AP of the terminal issues a message to the non-access stratum Modem NAS of the Modem to notify the Modem NAS that the WiFi (or VoWiFi) connection status of the terminal currently changes.

In step 502, the Modem NAS saves the current WiFi (or VoWiFi) connection status of the terminal as a global variable for other components to access.

Step 503, when the intelligent sensing Hub (Sensor Hub) of the terminal detects that the motion state of the terminal changes, the Sensor Hub informs the Modem NAS that the motion state changes.

In step 504, the Modem NAS saves the motion state of the terminal.

Step 505, the signal state of the current resident cell of the terminal reaches the measurement threshold.

In step 506, the radio resource control layer Modem RRC of the Modem acquires the WiFi (or VoWiFi) connection state and the motion state of the terminal from the Modem NAS.

In step 507, the Modem RRC determines whether to initiate a measurement process according to the WiFi (or VoWiFi) connection state, the motion state, and the signal state of the camping cell of the current terminal.

For example, when the current WiFi (or VoWiFi) connection of the terminal is in a disconnected state, or the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state and the terminal is in a moving state in a large range (the moving distance of the terminal is greater than the first threshold), the measurement process is initiated. The measurement process is not initiated when the terminal's current WiFi (or VoWiFi) connection is in a normal connection state, and the terminal is in a jogging/stationary state, and the current cell has resided for a period of time with good signal. Therefore, under the condition that the terminal is connected with WiFi (or VoWiFi), the terminal needs to initiate a measurement request due to poor signals, whether the measurement is ignored is judged according to the scene, the WiFi state and the cell measurement of the Modem are combined with each other, and the state combination of two chips can be formed to be the power consumption experience package navigation of the user.

By the example, when the terminal is connected with WiFi (or VoWiFi), the terminal is in a jogging/static state, and the current cell is already resident for a period of time with a good signal, and the terminal does not initiate a measurement request except for the current cell, so that redundant power consumption caused by a measurement process can be reduced, and an effect of saving power consumption can be achieved.

For example three, for the high power consumption behavior in the above case three, when the terminal is in a WiFi (or VoWiFi) connected state, if the signal state of the current camping cell of the terminal is good, including but not limited to RSRP, RSRQ, and SINR, and the signal of the camping cell reaches the reselection threshold, the terminal does not initiate a cell reselection process, so as to achieve the purpose of saving power consumption.

For example, when the terminal is in a WiFi (or VoWiFi) connected state, the terminal is in an idle state, is camped on an LTE (or NR) cell and has a current camped cell RSRP better than-115 dbm, an RSRQ better than-15, and an SINR better than 0, measures that the current camped cell reaches a threshold for reselection to GSM (or other systems), and does not initiate a reselection process.

Referring to fig. 6, a schematic flow chart of a power saving method for a terminal based on wlan connection according to the present invention is shown. As shown in fig. 6, the method flow includes the following steps:

in step 601, when the WiFi (or VoWiFi) connection state of the terminal changes (for example, changes from a normal connection state to a disconnection state, or changes from a disconnection state to a normal connection state), the application processor AP of the terminal issues a message to the non-access stratum Modem NAS of the Modem to notify the Modem NAS that the WiFi (or VoWiFi) connection state of the terminal currently changes.

In step 602, the Modem NAS saves the current WiFi (or VoWiFi) status of the terminal as a global variable for other components to access.

Step 603, the terminal finds that the signal state of the current resident cell reaches a reselection threshold.

In step 604, the Modem RRC obtains the WiFi (or VoWiFi) connection status and the motion status of the terminal from the Modem NAS.

In step 605, the Modem RRC determines whether to initiate a reselection process according to the WiFi (or VoWiFi) connection state, the motion state, and the signal state of the camping cell of the current terminal.

For example, when the current WiFi (or VoWiFi) connection of the terminal is in a disconnected state, or the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state, and the terminal is in a moving state in a large range (the moving distance of the terminal is greater than the first threshold), the reselection process is initiated. When the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state, and the terminal is in a jogging/static state, and the current cell already resides for a period of time, and the signal is good, reselection is not initiated. Therefore, under the condition that the terminal is connected with WiFi (or VoWiFi), the terminal needs to initiate a reselection request due to poor signals, whether the reselection request is ignored is judged according to a scene, the WiFi state and the Modem reselection are combined with each other, and two chip states can be combined to form a user power consumption experience package navigation.

By the example, when the terminal is connected with WiFi (or VoWiFi), the terminal is in a jogging/static state, and the current cell is already resident for a period of time with a good signal, and the terminal does not initiate a reselection process any more, so that redundant power consumption caused by the cell reselection process can be reduced, and the effect of saving power consumption can be achieved.

In a fourth example, for the high power consumption behavior in the fourth case, when the terminal is in a WiFi (or VoWiFi) connected state, if the signal state of the cell where the terminal currently resides is good, including but not limited to RSRP, RSRQ, and SINR, is higher than the threshold value, the network side initiates a redirection request, and then the terminal ignores the redirection request this time and does not initiate a redirection process, so as to achieve the purpose of saving power consumption.

Referring to fig. 7, a schematic flow chart of a power saving method for a terminal based on wlan connection according to the present invention is shown. As shown in fig. 7, the method flow includes the following steps:

in step 701, when the WiFi (or VoWiFi) connection state of the terminal changes (for example, changes from a normal connection state to a disconnection state, or changes from a disconnection state to a normal connection state), the application processor AP of the terminal issues a message to the non-access stratum Modem NAS of the Modem to notify the Modem NAS that the WiFi (or VoWiFi) connection state of the terminal currently changes.

In step 702, the NAS saves the current WiFi (or VoWiFi) connection status of the terminal as a global variable for other components to access.

In step 703, the Modem RRC of the terminal receives a redirection request from the base station.

In step 704, the Modem RRC obtains the WiFi (or VoWiFi) connection status and the motion status of the terminal from the Modem NAS.

Step 705, the Modem RRC determines whether to initiate a redirection procedure according to the WiFi (or VoWiFi) connection state, the motion state, and the signal state of the camping cell of the current terminal.

For example, when the current WiFi (or VoWiFi) connection of the terminal is in a disconnected state, or the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state and the terminal is in a moving state in a large range (the moving distance of the terminal is greater than the first threshold), the redirection process is initiated. When the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state, and the terminal is in a jogging/static state, and the current cell has resided for a period of time, the redirection process is not initiated. Therefore, under the condition that the terminal is connected with WiFi (or VoWiFi), the terminal needs to initiate a redirection process due to poor signals, whether the network side initiates a redirection request at this time is ignored or not is judged according to scenes, the WiFi state and Modem redirection are combined with each other, and two chip states can be combined to form a user power consumption experience package navigation.

By the example, when the terminal is connected with WiFi (or VoWiFi), the terminal is in a jogging/static state, and the current resident cell is already resident for a period of time with a good signal, and the terminal does not initiate a redirection process, so that redundant power consumption caused by the redirection process can be reduced, and the effect of saving power consumption can be achieved.

For example five, aiming at the high power consumption behavior of the above case five, when the terminal is in a WiFi (or VoWiFi) connected state, and the terminal initiates behaviors such as LAU, authentication, attach, TAU and the like in a current Location Area (LA), the terminal replies a rejection message to the network side due to terminal defaulting, where the cause value carried is #15(No viable cells in tracking Area), and the terminal does not initiate behaviors such as LAU, authentication, attach, TAU and the like to other LAs any more, so as to achieve the purpose of saving power consumption.

Referring to fig. 8, a schematic flow chart of a power saving method for a terminal based on wlan connection according to the present invention is shown. As shown in fig. 8, the method flow includes the following steps:

in step 801, when the WiFi (or VoWiFi) connection state of the terminal changes (for example, changes from a normal connection state to a disconnection state, or changes from a disconnection state to a normal connection state), the application processor AP of the terminal issues a message to the non-access stratum Modem NAS of the Modem to notify the Modem NAS that the WiFi (or VoWiFi) connection state of the terminal currently changes.

In step 802, the NAS saves the current WiFi (or VoWiFi) connection status of the terminal as a global variable for other components to access.

Step 803, the terminal initiates a registration request of actions such as TAU, authentication, LAU, attach and the like to the first LA through the Modem NAS in the arrearage state.

Step 804, the ModemNAS receives a response message from the base station, where the response message carries rejection information of No suitable cells (No suitable cells in tracking area) in the current area.

Step 805, the Modem NAS determines whether to initiate a registration process of actions such as TAU, authentication, LAU, attach (attach), and the like to other LAs according to the WiFi (or VoWiFi) connection state of the current terminal.

For example, when the current WiFi (or VoWiFi) connection of the terminal is in a disconnected state, a request initiation request for initiating actions such as TAU, authentication, LAU, attach, and the like to other LAs is initiated. When the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state, a registration request of actions such as TAU, authentication, LAU, attach and the like is not initiated to other LAs, so that the effect of saving power consumption can be achieved.

In step 806, when the WiFi (or VoWiFi) connection status of the terminal changes again, the application processor AP of the terminal issues a message to the Modem NAS to notify the WiFi (or VoWiFi) connection status of the Modem NAS terminal.

In step 807, the Modem NAS saves the terminal's current WiFi (or VoWiFi) connection status as a global variable for other components to access.

At step 808, the Modem NAS determines whether to reinitiate the registration request to another LA, and the relevant content of step 807 can refer to step 805.

By the example, when the current WiFi (or VoWiFi) connection of the terminal is in a normal connection state, and the terminal network side rejects for No enable cells in a tracking area, No registration request is initiated to other LAs any more, which can reduce redundant power consumption caused by initiating a registration process to other LAs, thereby achieving the effect of saving power consumption. When the current WiFi (or VoWiFi) connection of the terminal is in a disconnection state, the terminal initiates a registration request to other LA. Therefore, the WiFi state and the behavior of the Modem rejected by the network are combined with each other, and the two chip states can be combined to form the power consumption experience package navigation of the user.
