Description

Method for controlling maximum transmission power of mobile terminal and mobile terminal

Technical field

This application relates to the field of communication technologies, and in particular to a method for controlling the maximum transmission power of a mobile terminal and a mobile terminal.

Background technique

At present, mobile terminals have penetrated into all aspects of people's lives, and people will carry and use mobile terminals for a long time. In order to avoid harm to the human body caused by radio frequency signals during wireless communication of mobile terminals, relevant government regulations require restrictions on the power of radio frequency signals of mobile terminals. Specifically, the so-called specific absorption ratio (SAR) refers to the rate at which the human body absorbs radio frequency energy. In countries or regions where the average sampling organization exceeds 1 gram, the SAR limit is 1.6 W/kg, and in countries or regions where the average sampling organization exceeds 10 grams, the SAR limit is 2.0 W/kg. In other words, SAR requires the maximum transmit power of mobile terminals to be limited.

However, the transmit power of the mobile terminal directly affects the signal quality, that is, the smaller the transmit power, the worse the signal quality. The signal quality is directly related to the user experience. In other words, from the perspective of user experience, it is also hoped that the greater the transmit power of the mobile terminal, the better.

How to solve this contradiction so that the transmission power of mobile terminals can not only meet the relevant government's restriction requirements on SAR, but also improve the user experience has become an urgent problem to be solved.

Summary of the invention

The method for controlling the maximum transmission power of a mobile terminal and the mobile terminal provided in the present application can recognize that the mobile terminal is located at a specific position of the user's body, and determine the current maximum transmission power of the mobile terminal according to the specific position, which not only ensures user safety, but also Can improve signal quality.

In the first aspect, the method provided by this application includes: a mobile terminal establishes a communication connection with a wearable device; the mobile terminal receives first data of the wearable device, and determines whether the user is currently in an exercise state according to the first data; the first data includes At least one of the sensor data of the wearable device and the application data on the wearable device; if it is determined that the user is in motion, the mobile terminal obtains the second data; the second data is the data of the motion sensor of the mobile terminal; The data is matched with the preset motion template to determine that the mobile terminal is located at the first position or the second position of the user's body; if the mobile terminal is located at the first position of the user's body, the mobile terminal controls the transmission power of the wireless transmission signal not to be greater than the first maximum Transmission power; if the mobile terminal is located in the second position of the user's body, the mobile terminal controls the transmission power of the wireless transmission signal to be no greater than the second maximum transmission power; wherein the first maximum transmission power is different from the second maximum transmission power.

It can be seen that this application can determine the specific position of the mobile terminal on the user's body, and different maximum transmit powers can be used according to the different positions of the mobile terminal on the user's body. For example: when the mobile phone is on the limbs of the user, the SAR limit value when the limbs are used. That is, the maximum transmission power of the mobile phone can be increased (that is, when the mobile phone is located at the head or torso of the user relative to the mobile phone, the mobile phone can use a larger maximum transmission power) to ensure the signal quality of the user during communication. When it is determined that the mobile phone is not located on the user's limbs, the SAR limit value of the head or torso is used. That is, when the mobile phone is located on the limbs of the user, the mobile phone can use a smaller maximum transmission power to ensure the safety of the user.

In a possible implementation manner, the first position is the limbs, the second position is the head or the torso, and the first maximum transmission power is greater than the second maximum transmission power.

In a possible implementation, the sensor data of the wearable device includes any one or more of data from a motion sensor, data from a heart rate meter, and data from a pulse sensor; the application data of the wearable device includes whether to start a running application.

In some embodiments, it may be determined whether the user is in a motion state based on the motion data obtained by the motion sensor in the wearable device, such as acceleration data obtained by an acceleration sensor, angular velocity data obtained by a gyroscope sensor, etc. Since the movement of the limbs has a certain periodicity when the user is in an exercise state, the movement data of the wearable device also has a periodicity. Therefore, the periodicity of the exercise data of the wearable device can be used to determine whether the user is in an exercise state.

In other embodiments, the mobile phone can also determine whether the user is in an exercise state based on data obtained by other sensors in the wearable device. For example, the mobile phone can obtain the user's heart rate, blood pressure, pulse, sweat volume and other data through the heart rate meter, blood pressure meter, pulse sensor, humidity sensor, etc. in the wearable device to determine whether the user is currently exercising.

In still other embodiments, the mobile phone can also determine whether the user is in an exercise state based on the application currently running on the wearable device. For example, if the user opens an exercise-related application on the wearable device, such as running APP, it can be considered that the user is in exercise. status.

Thus, a variety of methods for determining whether the user is in an exercise state are provided. When the user is in a non-exercise state, the mobile phone may not perform subsequent operations. In this way, it is beneficial to reduce the data processing of the mobile phone when the user is in a non-exercise state, and is beneficial to reduce the power consumption of the mobile phone.

If the second preset sports template matches in the sports template, it is determined that the mobile terminal is located at the second position of the user's body.

Specifically, the real-time obtained mobile phone motion data can be compared with each motion template one by one, including comparing the value interval of each motion data and the waveform formed by each motion data to determine the specific position of the mobile phone on the user's body. After the movement data of the mobile phone is obtained in real time and the value interval and waveform of each movement data in a certain movement template are successfully matched, the matching with other movement templates can be stopped. In some embodiments, it is also possible to simplify the judgment logic for some more special waveforms in the motion template and reduce the amount of calculation. That is, it is preferred to match the mobile phone motion data acquired in real time with the special waveform, and if the matching is successful, other motion data acquired in real time are matched with other waveforms in the motion template where the special waveform is located. If the matching is also successful, it is determined that the mobile phone motion data obtained in real time matches the motion template, and no longer needs to be matched with other motion templates.

In a possible implementation manner, before the mobile terminal obtains the first data, the method includes: the mobile terminal receives an instruction from the user to enable the first function.

Among them, the first function means that the mobile phone automatically determines the specific position of the mobile terminal currently located on the user's body according to the technical solution provided in the embodiments of the present application, and determines the maximum transmit power of the mobile terminal to transmit wireless signals according to the specific position.

In a possible implementation manner, before the mobile terminal receives an instruction from the user to enable the first function, the method further includes: when the mobile terminal detects that the signal strength is less than the threshold, the mobile terminal prompts the user to enable the first function.

In a possible implementation manner, the method further includes: the mobile terminal prompts the user to move the mobile terminal away from the second position.

In a possible implementation manner, before the mobile terminal detects that the signal strength is less than the threshold, the method further includes: the mobile terminal is performing a call task or an Internet access task.

The pressure sensor 180A is used to sense pressure signals, and can convert the pressure signals into electrical signals. In some embodiments, the pressure sensor 180A may be provided on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors and so on. The capacitive pressure sensor may include at least two parallel plates with conductive material. When a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes. The mobile terminal 100 determines the strength of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the mobile terminal 100 detects the intensity of the touch operation according to the pressure sensor 180A. The mobile terminal 100 may also calculate the touched position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations that act on the same touch position but have different touch operation strengths may correspond to different operation instructions. For example: when a touch operation whose intensity is less than the first pressure threshold is applied to the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

The gyro sensor 180B may be used to determine the motion posture of the mobile terminal 100. In some embodiments, the angular velocity of the mobile terminal 100 around three axes (ie, x, y, and z axes) can be determined by the gyro sensor 180B. The gyro sensor 180B can be used for image stabilization. Exemplarily, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the mobile terminal 100, calculates the distance that the lens module needs to compensate according to the angle, and allows the lens to counteract the shake of the mobile terminal 100 through reverse movement to achieve anti-shake. The gyro sensor 180B can also be used for navigation and somatosensory game scenes.

The air pressure sensor 180C is used to measure air pressure. In some embodiments, the mobile terminal 100 calculates the altitude based on the air pressure value measured by the air pressure sensor 180C to assist positioning and navigation.

The magnetic sensor 180D includes a Hall sensor. The mobile terminal 100 may use the magnetic sensor 180D to detect the opening and closing of the flip holster. In some embodiments, when the mobile terminal 100 is a flip machine, the mobile terminal 100 may detect the opening and closing of the flip according to the magnetic sensor 180D. Furthermore, according to the detected opening and closing state of the leather case or the opening and closing state of the flip cover, features such as automatic unlocking of the flip cover are set.

The acceleration sensor 180E can detect the magnitude of the acceleration of the mobile terminal 100 in various directions (generally three axes). When the mobile terminal 100 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the terminal's posture, apply to horizontal and vertical screen switching, pedometer and other applications.

In some embodiments of the present application, the mobile terminal 100 can obtain the angular velocity of the mobile terminal 10 around three axes (ie, x, y, and z axes) through the gyro sensor 180B, and the The acceleration of each axis, and the acquired angular velocity and acceleration are sent to the processor 110, so that the processor 110 can determine which part of the user’s body the mobile terminal 100 is located according to the sensor data, for example: head, body trunk (not including limbs) ), or limbs, etc., and when it is determined that the mobile terminal 100 is located in a different part of the user's body, limit the wireless signal to be within different maximum transmission powers.

The proximity light sensor 180G may include, for example, a light emitting diode (LED) and a light detector such as a photodiode. The light emitting diode may be an infrared light emitting diode. The mobile terminal 100 emits infrared light to the outside through the light emitting diode. The mobile terminal 100 uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the mobile terminal 100. When insufficient reflected light is detected, the mobile terminal 100 may determine that there is no object near the mobile terminal 100. The mobile terminal 100 can use the proximity light sensor 180G to detect that the user holds the mobile terminal 100 close to the ear to talk, so as to automatically turn off the screen to save power.

The fingerprint sensor 180H is used to collect fingerprints. The mobile terminal 100 can use the collected fingerprint characteristics to implement fingerprint unlocking, access application locks, fingerprint photographs, fingerprint answering calls, etc.

The temperature sensor 180J is used to detect temperature. In some embodiments, the mobile terminal 100 uses the temperature detected by the temperature sensor 180J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold value, the mobile terminal 100 reduces the performance of the processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the mobile terminal 100 heats the battery 142 to avoid abnormal shutdown of the mobile terminal 100 due to low temperature. In some other embodiments, when the temperature is lower than another threshold, the mobile terminal 100 boosts the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

The touch sensor 180K may be disposed on the display screen 194, and the touch screen is composed of the touch sensor 180K and the display screen 194, which is also called a “touch screen”. The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. The visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K may also be disposed on the surface of the mobile terminal 100, which is different from the position of the display screen 194.

The motor 191 can generate vibration prompts. The motor 191 can be used for incoming call vibration notification, and can also be used for touch vibration feedback. For example, touch operations for different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. Acting on touch operations in different areas of the display screen 194, the motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminding, receiving information, alarm clock, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

The indicator 192 may be an indicator light, which may be used to indicate the charging status, power change, or to indicate messages, missed calls, notifications, and so on.

The SIM card interface 195 is used to connect to the SIM card. The SIM card can be inserted into the SIM card interface 195 or pulled out from the SIM card interface 195 to achieve contact and separation with the mobile terminal 100. The mobile terminal 100 may support 1 or N SIM card interfaces, and N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, etc. The same SIM card interface 195 can insert multiple cards at the same time. The types of the multiple cards can be the same or different. The SIM card interface 195 can also be compatible with different types of SIM cards. The SIM card interface 195 may also be compatible with external memory cards. The mobile terminal 100 interacts with the network through the SIM card to implement functions such as call and data communication. In some embodiments, the mobile terminal 100 uses an eSIM, that is, an embedded SIM card. The eSIM card can be embedded in the mobile terminal 100 and cannot be separated from the mobile terminal 100.

The software system of the mobile terminal 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present invention takes an Android system with a layered architecture as an example to exemplify the software structure of the mobile terminal 100.

FIG. 2 is a block diagram of the software structure of the mobile terminal 100 according to an embodiment of the present invention.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Communication between layers through software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

The application layer can include a series of application packages.

As shown in Figure 2, the application layer can include application packages such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

The application framework layer provides application programming interfaces (application programming interface, API) and programming frameworks for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer can include a window manager, a content provider, a view system, a phone manager, a resource manager, and a notification manager.

The window manager is used to manage window programs. The window manager can obtain the size of the display, determine whether there is a status bar, lock the screen, take a screenshot, etc.

The content provider is used to store and retrieve data and make these data accessible to applications. The data may include video, image, audio, phone calls made and received, browsing history and bookmarks, phone book, etc.

The view system includes visual controls, such as controls that display text and controls that display pictures. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface that includes a short message notification icon may include a view that displays text and a view that displays pictures.

The phone manager is used to provide the communication function of the mobile terminal 100. For example, the management of the call status (including connecting, hanging up, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and it can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears in the status bar at the top of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, prompt text information in the status bar, sound a prompt tone, terminal vibration, flashing indicator light, etc.

Android Runtime includes core libraries and virtual machines. Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function functions that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library can include multiple functional modules. For example: surface manager (surface manager), media library (Media Libraries), three-dimensional graphics processing library (for example: OpenGL ES), 2D graphics engine (for example: SGL), etc.

The surface manager is used to manage the display subsystem and provides a combination of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as still image files. The media library can support multiple audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to realize 3D graphics drawing, image rendering, synthesis, and layer processing.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

In the following, the working procedures of the software and hardware of the mobile terminal 100 will be exemplified in conjunction with capturing a photo scene.

When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, etc.). The original input events are stored in the kernel layer. The application framework layer obtains the original input event from the kernel layer, and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and the control corresponding to the click operation is the control of the camera application icon as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer. The camera 193 captures still images or videos.

The technical solutions involved in the following embodiments can all be implemented in the mobile terminal 100 having the above hardware architecture and software architecture.

In the following, a mobile terminal is taken as an example of a mobile phone, and the technical solutions provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings.

First of all, it should be noted that the strength of the radio frequency signal of a mobile phone has different effects on different parts of the human body. For example, it has a greater impact on the head and torso (excluding the limbs) and less on the limbs. As a result, the SAR limits for various parts of the human body vary from country to country. As shown in Table 1, the European Union (Communate Europpene, CE) and Federal Communications Commission (Federal Communication Commission, FCC) list of SAR restrictions on various parts of the human body. It can be seen that the SAR limit requirements for the head and torso are lower than the SAR limit for the limbs.

Table I

地区/国家Region/Country	头部head	身体躯干Body torso	四肢Limbs
CE(采样组织平均超过10克)CE (the average sampled tissue exceeds 10 grams)	2.0瓦/公斤2.0W/kg	2.0瓦/公斤2.0W/kg	4.0瓦/公斤4.0W/kg
FCC(采样组织平均超过1克)FCC (the average sample organization exceeds 1 gram)	1.6瓦/公斤1.6W/kg	1.6瓦/公斤1.6W/kg	4.0瓦/公斤4.0W/kg

However, the prior art cannot distinguish whether the mobile phone is located on the limbs (for example, when the user holds the mobile phone) or the torso of the body. Therefore, the SAR limit value of the body torso is always used, that is, the maximum transmission power used by the mobile phone is restricted to be small.

In this application, considering that there are many scenes when the mobile phone is located on the user’s limbs, for example: the user holds the mobile phone while walking, running, etc., or the user wears the mobile phone on the wrist, arm, leg, etc., in this application, the mobile phone can be determined When it is on the user’s limbs, and when the phone is on the user’s limbs, the SAR limit value for the limbs is used. That is, the maximum transmission power of the mobile phone can be increased (that is, when the mobile phone is located at the head or torso of the user relative to the mobile phone, the mobile phone can use a larger maximum transmission power) to ensure the signal quality of the user during communication. When it is determined that the mobile phone is not located on the user's limbs, the SAR limit value of the head or torso is used. That is, when the mobile phone is located on the limbs of the user, the mobile phone can use a smaller maximum transmission power to ensure the safety of the user.

Or, when the mobile phone is on the user's head or torso, if the signal quality is poor, the user can also be prompted to remove the mobile phone from the user's head or torso, so that the mobile phone can increase the transmission power, thereby improving the signal quality of the user during communication , Improve user experience.

According to the experimental data, when the user is at rest, the mobile phone's motion data (for example: the motion data obtained by the motion sensor) will not change significantly and steadily, and it is not easy to determine which part of the user's body the mobile phone is at this time. Location. When the user is in an exercise state, the motion data of the mobile phone (for example: the motion data obtained by the motion sensor) will change regularly. Moreover, when the mobile phone is located in different parts of the user's body, the law of the exercise data is different. Therefore, the technical solution provided by the embodiments of the present application can determine the specific part of the user's body where the mobile phone is located according to different laws of the mobile phone's motion data, thereby determining the maximum transmission power of the mobile phone.

Since the user is in an exercise state (such as walking, running), the user’s limbs swing more obviously, and the wearable devices worn by the user (also called wearable products, wearable products, etc.), such as: smart watches, bracelets, wrists Belts, etc., can obtain the corresponding motion data through its built-in motion sensor, etc., and the current state of the user can be obtained through a certain algorithm. For example, when the wearable device is worn on the user’s wrist, the user is in motion (such as walking , Running), the movement data (such as acceleration, angular velocity, etc.) of the wearable device has a periodic change rule. Then, when it is determined that the exercise data of the wearable device has the periodic change rule, it can be confirmed that the user is in an exercise state, otherwise it can be confirmed that the user is in a non-exercise state (for example, sitting still). For another example: when the wearable device has a heart rate meter or pulse meter built in, when it is determined that the user's heart rate or pulse is in a specific interval, the user can be confirmed to be in an exercise state, otherwise it can be confirmed that the user is in a non-exercise state. For details, refer to the related description of step S302. Therefore, in some embodiments of the present application, the mobile phone can use the motion sensor of the wearable device to determine whether the user is in a motion state. When it is determined that the user is in an exercise state, the mobile phone is further determined based on the mobile phone's motion data to determine which part of the user's body the mobile phone is located, and how much transmission power to use.

As shown in FIG. 3, a schematic flow chart of a method for controlling the maximum transmit power of a mobile phone provided by an embodiment of this application specifically includes:

S301. The mobile phone establishes a communication connection with the wearable device.

Specifically, the mobile phone can establish a wireless connection with the wearable device through wireless connection methods such as Bluetooth, NFC, WIFI, or the like, and can also establish a wired connection with the wearable device through a USB interface or the like. Here is an example of establishing a connection between a mobile phone and a wearable device via Bluetooth. In specific implementation, classic Bluetooth connection or low-power Bluetooth connection may be used, which is not limited in the embodiment of the present application.

In one scenario, as shown in FIG. 4, it is a schematic diagram of establishing a connection between a mobile phone and a wearable device (such as a smart watch) via Bluetooth. After the mobile phone is successfully paired with the smart watch, the mobile phone can obtain data related to the user's exercise in the smart watch, such as the data of certain sensors in the smart watch (for example, the exercise data obtained by the motion sensor, or the heart rate meter built in the smart watch, Data from pulse sensors, etc.), and data from related applications (such as running APP, etc.) in the smart watch (for example, whether the running APP is turned on), etc.

For example: after the mobile phone is successfully paired with the smart watch, the mobile phone can automatically obtain data related to the user's movement in the smart watch. Alternatively, the mobile phone may display the interface 400 and ask the user whether to obtain data related to the user's exercise on the smart watch. In response to the user clicking the "Yes" button on the interface 400, the mobile phone actively acquires data on the smart watch.

For another example, after the mobile phone is successfully paired with the smart watch, the smart watch can also automatically report data related to the user's exercise to the mobile phone. Or, the smart watch displays an interface 403, asking the user whether to upload data related to the user's exercise on the smart watch. In response to the user clicking the "Yes" button on the interface 403, the smart watch actively reports data related to the user's exercise to the mobile phone.

In another scenario, since the prior art cannot distinguish whether the mobile phone is located on the extremities (for example, when the user is holding the mobile phone) or the body trunk, the SAR limit value of the body trunk is always used. In other words, in the prior art, mobile phones always use a smaller maximum transmit power. However, in this application, it can be determined whether the mobile phone is located on the extremities or the head or torso. Therefore, when it is determined that the mobile phone is located on the extremities, the mobile phone can be larger than when the mobile phone is located on the user’s head or torso. The maximum transmit power. When it is determined that the mobile phone is located at the head or torso position, the mobile phone can use a smaller maximum transmit power when it is located on the user's limbs relative to the mobile phone. In other words, the mobile phone can automatically adjust the maximum transmit power of the mobile phone according to the specific location of the mobile phone on the user's body. For the convenience of explanation, this function can be called the "adaptive maximum transmit power" function of the mobile phone in this article. In a specific implementation, the mobile phone can enable this function by default, or it can determine whether to enable this function according to the user's operation.

For example: an interface 500 of a system setting of a mobile phone as shown in FIG. 5. On the interface 500, there is a function item 501 of turning on or off the "adaptive maximum transmit power". In response to the user's turn-on operation, the mobile phone turns on the function. In one example, after the mobile phone turns on this function, the mobile phone can automatically obtain relevant data of the wearable device connected to it. In another example, after the mobile phone detects that a connection is established with the wearable device, the user may also be prompted whether to enable the "adaptive maximum transmit power" function.

In another scenario, when a user makes a call, or during a call, or when the user uses a cellular mobile network or WIFI to surf the Internet, if the mobile phone detects poor signal quality (for example, the signal strength is less than the threshold), The user can be prompted to turn on the "adaptive maximum transmit power" function, and the user is prompted to move the mobile phone away from the user's head and torso, so that the mobile phone can increase the maximum transmit power and improve the signal quality.

For example: Take the scenario where a user makes a phone call as an example. As shown in Figure 6, an interface 600 for a user to make a call. If it is detected that the signal quality of the mobile phone is poor, the user can be prompted to enable the "adaptive maximum transmit power" function, as shown in interface 601. In response to the user clicking the "Yes" button 602, the mobile phone may display an interface 603, prompting the user to move the mobile phone away from the user's head and torso. In this way, using the method provided by the embodiments of the present application, when the mobile phone determines that the mobile phone is not located on the user's head or torso, it can automatically increase the maximum transmission power, improve the signal quality of the mobile phone, ensure the user's call quality, and improve the user experience.

S302: The mobile phone obtains data of the wearable device, and determines that the user is in an exercise state or a non-exercise state.

Among them, the user is in the state of exercise, including the state of the user in walking, running, cycling, etc. The user is in a non-exercise state, including the state where the user is sitting still, taking a vehicle, etc.

In some embodiments of the present application, the mobile phone can determine whether the user is in motion based on the motion data obtained by the motion sensor in the wearable device, such as acceleration data obtained by the acceleration sensor, angular velocity data obtained by the gyroscope sensor, etc. Since the movement of the limbs has a certain periodicity when the user is in an exercise state, the movement data of the wearable device also has a periodicity. Therefore, the periodicity of the exercise data of the wearable device can be used to determine whether the user is in an exercise state.

In other embodiments of the present application, the mobile phone can also determine whether the user is in an exercise state based on data obtained by other sensors in the wearable device. For example, the mobile phone can obtain the user's heart rate, blood pressure, pulse, sweat volume and other data through the heart rate meter, blood pressure meter, pulse sensor, humidity sensor, etc. in the wearable device to determine whether the user is currently exercising. When the user is in a different exercise state, the user's heart rate, blood pressure, pulse, and sweating volume all have certain characteristics. Therefore, it is also possible to determine whether the user is in an exercise state based on the characteristics of the user's heart rate, blood pressure, pulse, and sweat volume.

In still other embodiments of the present application, the mobile phone can also determine whether the user is in an exercise state based on the application currently running on the wearable device. For example, the user opens a sports-related application on the wearable device, such as running APP, etc. Think that the user is in motion.

It is understandable that the above description is based on the example in which the mobile phone obtains the data of the wearable device and judges the current state of the user. Of course, the wearable device can also make a judgment based on its own data to determine whether the user is in an exercise state or a non-exercise state, and notify the mobile phone of the judgment result. Then, the mobile phone performs subsequent operations according to the judgment result.

Since the mobile phone determines the current state of the user according to the data of the wearable device, that is, when the user is in an exercise state, the mobile phone performs subsequent operations. When the user is in a non-exercise state, the mobile phone may not perform subsequent operations. In this way, it is beneficial to reduce the data processing of the mobile phone when the user is in a non-exercise state, and is beneficial to reduce the power consumption of the mobile phone. In addition, after the mobile phone makes a preliminary judgment on the user's motion state, it will also help simplify the complexity of subsequent data processing.

Of course, in other embodiments of the present application, the mobile phone can also use the built-in sensors and installed applications of the mobile phone to determine whether the user is in motion. For example: mobile phones have built-in heart rate monitors, blood pressure monitors, pulse sensors, humidity sensors, etc. The mobile phone can obtain exercise-related data through these sensors to determine whether the user is in a state of exercise. The judgment method and the data obtained from the sensor in the wearable device The judgment method is similar and will not be repeated here. For another example: when the user opens the sports-related APP in the mobile phone, it can also be considered that the user is in an exercise state.

S303. If the mobile phone determines that the user is in an exercise state, obtain the mobile phone's exercise data.

As explained in the foregoing, when the user is in an exercise state, when the mobile phone is carried in different positions on the user's body (that is, when the mobile phone is in different positions on the user's body), the movement data obtained by the mobile phone motion sensor also has different changing laws. Among them, when the mobile phone is located at different positions on the user's body, the different changing laws of the exercise data will be introduced in detail when the exercise template is introduced in step S304, and will not be repeated here.

Then, it can be determined that the mobile phone is located at a specific position on the user's body at this time according to the change law of the mobile phone's motion data. To do this, you need to get the mobile phone's exercise data first. Generally speaking, mobile phones have built-in motion sensors, such as acceleration sensors, gyroscope sensors, gravity sensors, and rotation vector sensors. These sensors may be hardware or software, which is not specifically limited in the embodiment of the present application. The mobile phone can obtain the movement data of the mobile phone through any one or several of the aforementioned movement sensors. It is understandable that in this application, some simple data processing can also be performed on the motion data obtained from the sensor, for example: removing abnormal points that deviate from the curve of other data, and filtering the original sensor data obtained Wait.

It should be noted that the specific exercise data that the mobile phone needs to obtain can be determined by the pre-stored exercise template in step S304. For example: if the motion data used in the motion template is acceleration and angular velocity, then the mobile phone can obtain the acceleration of the mobile phone on three axes through the acceleration sensor, and the acceleration of the mobile phone around the three axes through the gyroscope sensor. For another example: if the motion data used in the motion template also includes the data of the rotation vector of the mobile phone, the mobile phone also needs to obtain the data of the rotation vector from the rotation vector sensor.

In a specific implementation, the mobile phone can start acquiring the motion data of the corresponding sensor when the "adaptive maximum transmit power" function is turned on and the user is determined to be in a motion state. In another specific implementation, the mobile phone can also acquire the motion data of the corresponding sensor after turning on the "adaptive maximum transmit power" function. When it is determined that the user is in an exercise state, the acquired exercise data is directly used for matching and other processing. In this way, it is beneficial to reduce the time for the mobile phone to obtain the motion data and improve the processing efficiency.

S304: The mobile phone matches the acquired motion data of the mobile phone with a pre-stored motion template, and determines whether the mobile phone is located at the first position or the second position of the user's body at this time.

Among them, the first position includes the user's head, and torso (excluding limbs). The second position includes the user's limbs, such as hands, legs, feet, and so on. Here to distinguish whether the mobile phone is located in the first position of the user's body or the second position of the user's body is to limit the power of the wireless signal transmitted by the mobile phone to different maximum transmission powers according to the different positions of the mobile phone on the user's body. , To achieve the effect of not only ensuring user safety, but also improving the signal quality of the mobile phone.

Experimental data has proved that when the user is in an exercise state, when the mobile phone is in a different position on the user's body, the motion data obtained by the mobile phone's motion sensor also has a different law of change. Therefore, a large number of experiments can be performed first to sample the motion data when the mobile phone is in different positions of the user's body and perform different exercises, and determine the common features of the motion data when the mobile phone is in different positions of the user to form a motion template.

Take the motion data including acceleration data and angular velocity data, and sample the mobile phone on the user's head, torso (excluding limbs), hands, legs, and feet as an example.

For example, as shown in Figure 7, it is an example of a motion template with a mobile phone on the user's head. The motion template includes 8 seconds of motion data. The motion data used includes the acceleration of the mobile phone on the three axes and the angular velocity of the mobile phone on the three axes. It can be seen that when the mobile phone is on the user's head, the size of the mobile phone's motion data has such characteristics: the acceleration on the X axis is [-0.6, 0.6], and the acceleration on the Y axis is [-2.6, 0.4] , The acceleration on the Z axis is [-1.8, 0.3]. The angular velocity on the X axis is [-1.4, 1.4], the angular velocity on the Y axis is [-0.9, 1.2], and the angular velocity on the Z axis is [-0.6, 1.2]. In addition, the waveform diagram formed by each motion data in a continuous period of time is similar to the waveform diagram corresponding to each motion data in FIG. 7.

Later, when it is determined that the mobile phone is located at the specific position of the user’s body, if the values of the various motion data of the mobile phone obtained in real time are located in the above corresponding intervals, and the waveform formed by each motion data is similar to the various motions in the motion template in Fig. 7 If the waveforms of the data are matched, it can be considered that the mobile phone is located on the user's head. Among them, to determine whether the value of each motion data of the mobile phone obtained in real time is similar to the waveform corresponding to each motion data in the motion template (that is, whether it matches), the least square method, the cross-correlation function calculation method, or other waveform templates can be used Any one or several of the detection algorithms are not limited in the embodiment of the present application.

In some examples, the mobile phone can also be combined with other methods to further verify whether the above judgment is accurate. For example, it is possible to further verify whether the mobile phone is on the user's head based on the task or application currently performed by the mobile phone and/or data from other sensors. In a specific implementation, if it is determined that the mobile phone is performing a call task, and the proximity sensor data shows that the mobile phone is close to the human body, it can be considered that the user is using the mobile phone to answer the call, further verifying that the mobile phone is indeed on the user's head. Or, if it is determined that the mobile phone is performing a call task, and the speaker is not turned on and the Bluetooth headset is not connected, it can be considered that the user is using the handset of the mobile phone to answer the call and further verify that the mobile phone is indeed on the user's head.

Another example: as shown in Figure 8, it is an example of a motion template with a mobile phone in the user's hand. The motion template includes 8 seconds of motion data. The motion data used includes the acceleration of the mobile phone on three axes and the angular velocity of the mobile phone on the three axes. It can be seen that when the mobile phone is in the user's hand, the size of the mobile phone's motion data has such characteristics: the acceleration on the X axis is [-0.6, 1.2], and the acceleration on the Y axis is [-5, 0.3] , The acceleration on the Z axis is [-1.1, 0.5]. The angular velocity on the X axis is [-2.5, 5], the angular velocity on the Y axis is [-1.4, 2.2], and the angular velocity on the Z axis is [-3, 3.5]. In addition, the waveform diagram formed by each motion data in a continuous period of time is similar to the waveform diagram corresponding to each motion data in FIG. 8.

Subsequently, when it is determined that the mobile phone is located at the specific position of the user’s body, if the values of each movement data of the mobile phone obtained in real time are located in the above corresponding intervals, and the waveform formed by each movement data is similar to the movement in the movement template in Fig. 8 If the waveforms of the data are matched, it can be considered that the mobile phone is in the user's hand.

It should be noted that in the exercise template, the data is obtained by sampling the mobile phone on the user's wrist. In other examples, it is also possible to place the mobile phone in the upper arm, the wrist, and the palm for sampling respectively, that is, to obtain the motion template of the mobile phone in each position of the hand. In this way, the precision and accuracy of the motion template can be improved, and the specific position of the mobile phone can be further determined. In this case, different operations can also be performed according to the different positions of the mobile phone on the hand. For example: when it is determined that the mobile phone is located on the upper arm, since it is closer to the torso of the human body than other positions of the hand, the mobile phone can also use a smaller maximum transmission power at this time to further ensure the safety of the user. When it is determined that the mobile phone is located in the wrist and the palm of the hand, a larger maximum transmission power can be used, which will not affect the safety of the user, but can also improve the signal quality of the mobile phone.

In still other examples, when the mobile phone is located in the user's hand (or more specific parts, upper arm, wrist, palm), sampling can be performed for different movements of the user (for example, walking, running, cycling, etc.). That is, the exercise template when the user performs different exercises when the mobile phone is in the user's hand is obtained. In this way, it is also beneficial to improve the precision and accuracy of the motion template.

Another example: as shown in Fig. 9, it is an example of a motion template where the mobile phone is located on the user's torso. The motion template includes 8 seconds of motion data. The motion data used includes the acceleration of the mobile phone on three axes and the angular velocity of the mobile phone on the three axes. It can be seen that when the mobile phone is located on the user’s torso, the size of the mobile phone’s motion data has the following characteristics: the acceleration on the X axis is [-4, 0.3], and the acceleration on the Y axis is [-0.9, 0.6], The magnitude of the acceleration on the Z axis is [-0.1, 1.4]. The angular velocity on the X axis is [-1.4, 1.4], the angular velocity on the Y axis is [-0.9, 0.9], and the angular velocity on the Z axis is [-0.8, 0.8]. In addition, the waveform diagram formed by each motion data in a continuous period of time is similar to the waveform diagram corresponding to each motion data in FIG. 9.

Subsequently, when it is determined that the mobile phone is located at the specific position of the user’s body, if the values of each movement data of the mobile phone obtained in real time are located in the above corresponding intervals, and the waveform formed by each movement data is similar to the movement in the movement template in Fig. 9 If the waveforms of the data are matched, it can be considered that the mobile phone is located on the user's torso.

In other examples, the mobile phone can also be combined with other methods to further confirm whether the judgment is accurate. For example, the task or application running on the mobile phone and/or data from other sensors can be combined to further verify whether the judgment that the mobile phone is located on the torso is accurate. For example: when the mobile phone is running games, videos, navigation and other tasks, and it can be determined that the mobile phone is in a landscape state based on the mobile phone's gravity sensor and other data, then it may be that the user is holding the mobile phone to play games, watch videos, watch navigation, etc. . Since the user will control the mobile phone to be in a relatively stable state, the movement data obtained by the mobile phone's motion sensor will change less at this time, which may match the waveform of the mobile phone on the torso. Therefore, in this case, it can be determined that the mobile phone is in the user's hand. Compared to when the mobile phone is located on the head or torso, the mobile phone can use a larger maximum transmission power at this time. Of course, this scenario may not be distinguished, and a smaller maximum transmission power may be used to ensure user safety, which is not limited in the embodiment of the present application.

Another example: as shown in FIG. 10, it is an example of a motion template where the mobile phone is located on the user's leg. The motion template includes 8 seconds of motion data. The motion data used includes the acceleration of the mobile phone on three axes and the angular velocity of the mobile phone on the three axes. It can be seen that when the mobile phone is on the user's leg, the size of the mobile phone's motion data has such characteristics: the acceleration on the X axis is [-7, 8], and the acceleration on the Y axis is [-3, 13] , The acceleration on the Z axis is [-9, 8]. The angular velocity on the X axis is [-2, 8], the angular velocity on the Y axis is [-3.5, 4], and the angular velocity on the Z axis is [-14, 14]. Moreover, the waveform diagram formed by each motion data in a continuous period of time is similar to the waveform diagram corresponding to each motion data in FIG. 10. Among them, the acceleration data on the Z axis does not have obvious detection characteristics.

Subsequently, when it is determined that the mobile phone is located at the specific position of the user’s body, if the values of each movement data of the mobile phone obtained in real time are located in the corresponding intervals mentioned above, and the waveform formed by each movement data is similar to the movement in the movement template in Fig. 10 If the waveforms of the data are matched, it can be considered that the mobile phone is located on the user's leg.

Another example: as shown in Figure 11, it is an example of a motion template with a mobile phone located on the user's foot. The motion template includes 8 seconds of motion data. The motion data used includes the acceleration of the mobile phone on three axes and the angular velocity of the mobile phone on the three axes. It can be seen that when the mobile phone is on the user’s foot, the size of the mobile phone’s motion data has such characteristics: the acceleration on the X axis is [-12, 12], and the acceleration on the Y axis is [-10, 14] , The acceleration on the Z axis is [-11, 7]. The angular velocity on the X axis is [-10, 7], the angular velocity on the Y axis is [-16, 10], and the angular velocity on the Z axis is [-5, 5.5]. Moreover, the waveform diagram formed by each motion data in a continuous period of time is similar to the waveform diagram corresponding to each motion data in FIG. 11.

Subsequently, when it is determined that the mobile phone is located at the specific position of the user’s body, if the values of each movement data of the mobile phone obtained in real time are located in the corresponding intervals mentioned above, and the waveform formed by each movement data is similar to each movement in the movement template in Fig. 11 If the waveforms of the data are matched, it can be considered that the mobile phone is located on the user's foot.

In a word, the real-time obtained mobile phone motion data is compared with the above-mentioned motion template one by one, including the comparison of the value interval of each motion data and the waveform formed by each motion data to determine the specific position of the mobile phone on the user's body. After the movement data of the mobile phone is obtained in real time and the value interval and waveform of each movement data in a certain movement template are successfully matched, the matching with other movement templates can be stopped. In some embodiments, it is also possible to simplify the judgment logic for some more special waveforms in the motion template and reduce the amount of calculation. That is, it is preferred to match the mobile phone motion data acquired in real time with the special waveform, and if the matching is successful, other motion data acquired in real time are matched with other waveforms in the motion template where the special waveform is located. If the matching is also successful, it is determined that the mobile phone motion data obtained in real time matches the motion template, and no longer needs to be matched with other motion templates.

For example: comparing the various motion templates in Figure 7 to Figure 11, it can be observed that in the motion template shown in Figure 8 (when the mobile phone is in the hand), the waveform formed by the value of the angular velocity in the Z-axis direction is different from other motion templates.的waveform. Therefore, the acquired waveform diagram of the current angular velocity of the mobile phone on the Z axis can be matched with the waveform diagram in the motion template first. If the matching is successful, it can be preliminarily confirmed that the mobile phone is in the user's hand. Then, the obtained other motion data is matched with other motion data in the hand motion template. If the matching is successful again, confirm that the mobile phone is in the user's hand. Then, there is no need to match with other sports templates, reducing the amount of calculation of the mobile phone and improving the recognition efficiency.

For another example: comparing the various exercise templates in Figure 7 to Figure 11, it can be observed that in the exercise template shown in Figure 10 (when the mobile phone is on the leg), the waveform formed by the value of the acceleration in the Z-axis direction is different from other sports Template waveform. Therefore, it is also possible to match the acquired waveform diagram of the current acceleration of the mobile phone on the Z axis with the waveform diagram in the motion template first. If the matching is successful, it can be preliminarily confirmed that the mobile phone is located on the user's leg. Then, the obtained other motion data is matched with other motion data in the motion template of the leg. If the match is successful again, it is confirmed that the phone is located on the user's leg. Then, there is no need to match with other sports templates, reducing the amount of calculation of the mobile phone and improving the recognition efficiency.

It is understandable that the above description is based on the acceleration and angular velocity of the mobile phone as an example. When the user is in an exercise state, other sports data of the mobile phone may also show a regular trend of change. Therefore, it is also possible to determine which part of the user's body the mobile phone is located according to the changing trend of other sports data. This embodiment of the application does not do this. limited.

It should also be noted that the motion template pre-stored in the mobile phone may be obtained by analyzing the motion data in the sample. The motion data in the sample can be average data obtained by a specific experimenter carrying a mobile phone at different positions on the body, or average data obtained by collecting a large number of users carrying a mobile phone at different positions on the body. Since people have different exercise postures during exercise, the exercise data of mobile phones will also be different. Therefore, the pre-stored exercise template in the mobile phone can also collect the mobile phone user’s exercise data after the mobile phone is used, and update the exercise template to make the exercise template more accurate and help improve the identification of the specific position of the mobile phone on the user’s body. Accuracy.

S305. If it is determined that the mobile phone is located at the first position of the user's body, the mobile phone controls the transmission power of the wireless transmission signal to be less than or equal to the first maximum transmission power. If it is determined that the mobile phone is located at the second position of the user's body, the mobile phone controls the power of the wireless transmission signal to be less than the second maximum transmission power.

Wherein, the first position may be a position such as a hand, a leg, or a foot. The first maximum transmission power is greater than the second maximum transmission power.

In other words, when the mobile phone is located in the user's hands, legs, feet, etc., the power of the wireless signal transmitted by the mobile phone is restricted to be within the first maximum transmit power, which can be higher than the second maximum transmit power, which can appropriately improve the mobile phone's power. Signal quality, and meet the requirements of relevant regulations for SAR. When the mobile phone is located at the head and torso of the user, limit the wireless signal power transmitted by the mobile phone to be within the second maximum transmit power to meet the requirements of the relevant regulations for SAR and ensure the safety of the user.

Among them, when the mobile phone controls the transmission power of the wireless signal, the receiver and transmitter can be turned on or off, the impedance matching circuit can be adjusted, and the front-end module (FEM) radio frequency inserted between the radio frequency transceiver circuit and the antenna structure can be configured. Switches in the circuit, adjustable switches, tunable circuits, and other adjustable circuit elements formed as part of the antenna or coupled to the antenna or the signal path associated with the antenna, adjustable power amplifier gain settings, and control the transceiver output power , And other technical means conceivable by those skilled in the art, which are not limited in the embodiment of the present application.

The technical solutions provided in the embodiments of the present application will be described below in conjunction with specific scenarios in which users use mobile phones.

For example: as shown in Figure 12, the user is in an exercise state as an example. From T0 to T1, the user places the mobile phone in the pocket of the user's clothes or pants, or places the mobile phone in a backpack or diagonal bag carried by the user. At this time, using the technical solutions in the above-mentioned embodiments of the present application, it can be determined that the mobile phone's motion data matches the motion template described in FIG. 9, for example, the mobile phone is located on the user's torso, and the second maximum transmit power is used. That is, the mobile phone controls the transmission power of the wireless signal within the second maximum transmission power to meet the SAR requirements of relevant regulations and ensure the safety of users. At T1, the user takes the mobile phone out of the pocket or bag, that is, the mobile phone is in the user's hand at this time. At this time, using the technical solutions in the above-mentioned embodiments of the present application, it can be determined that the mobile phone's motion data matches the motion template described in FIG. 8, for example, and the mobile phone is in the user's hand. The first maximum transmission power can be used, where , The first maximum transmission power is greater than the second maximum transmission power. In some examples, the mobile phone may display a prompt interface 1201 (for example, at time T2), prompting the user that the mobile phone will (or has) increased the maximum transmit power. At time T1 to T3, or time T2 to T3, the mobile phone uses the first maximum transmit power. That is, the mobile phone controls the transmission power of the wireless signal within the first maximum transmission power, which not only satisfies the SAR requirements of relevant regulations, but also improves the signal quality of the mobile phone. At time T3, the mobile phone receives an incoming call, and the user places the mobile phone to the ear to answer the call. At this time, using the technical solutions in the foregoing embodiments of the present application, it can be determined that the mobile phone's motion data matches the motion template described in FIG. 7, for example, to determine that the mobile phone is located on the user's head, and the second maximum transmission power needs to be used. In some examples, the mobile phone may display a prompt interface 1202 (for example, at time T4), prompting the user that the mobile phone will (or has) reduced the maximum transmit power. After T3 or T4, the mobile phone uses the second maximum transmit power.

It should be noted that the mobile phone may display the above prompt interface, or not display the above prompt interface, and may also prompt the user in other ways, such as using voice, vibration, animation and other prompt methods, etc. This embodiment of the application does not do this limited.

For another example, the interface circuit 1102 may be used to send signals to other devices (such as the processor 1101). Exemplarily, the interface circuit 1102 may read instructions stored in the memory, and send the instructions to the processor 1101.
