Background

In some implementations, when the electronic device implements the above functions, the electronic device may generally communicate with the base station or the satellite based on the antenna transmitting and receiving signals, but in the implementations, the electronic device may have a poor network signal, a poor positioning time and positioning accuracy of GPS navigation, or a slow data uploading or downloading speed, so that the communication capability of the electronic device is degraded, and the user experience is reduced.

Disclosure of Invention

The embodiment of the application provides a frame rate control method and a related device, when electronic equipment detects that the intensity of a signal received by an antenna is weak, the electronic equipment can reduce the transmission of a data stream by reducing the frame rate of screen refreshing, thereby reducing the noise of external radiation and reducing the interference on the signal received by the antenna.

In a first aspect, an embodiment of the present application provides a frame rate control method, including:

At a first moment, a foreground of the electronic equipment runs a first application, the strength of an antenna receiving signal of the electronic equipment does not meet the preset signal weak condition, and the frame rate of the electronic equipment is a first frame rate; at a second moment, continuously running a first application by a foreground of the electronic equipment, wherein the strength of a signal received by an antenna of the electronic equipment meets a preset signal weakness condition, and the frame rate of the electronic equipment is a second frame rate, wherein the second frame rate is smaller than the first frame rate, and the second moment is later than the first moment; at a third moment, the foreground of the electronic equipment continuously runs the first application, the strength of the antenna receiving signal of the electronic equipment does not meet the preset signal weak condition, the frame rate of the electronic equipment is a third frame rate, wherein the third frame rate is larger than the second frame rate, the third frame rate is equal to the first frame rate, or the third frame rate is unequal to the first frame rate, and the third moment is later than the second moment. Therefore, when the electronic equipment detects that the intensity of the signal received by the antenna is weaker, the electronic equipment can limit the frame rate of the application running in the foreground so as to reduce the interference on the signal received by the antenna, so that the communication network is improved when a user uses the electronic equipment, and the user experience is improved.

In a possible implementation manner, the electronic device determines whether an antenna receiving signal of the electronic device meets a preset signal weakness condition according to an AGC gear of the electronic device, an AGC gain of the electronic device, or a signal strength value of the electronic device. In this way, by judging the strength of the signal received by the antenna, the frame rate of the electronic device is limited when the signal is weak, so that the interference on the signal received by the antenna can be reduced.

In a possible implementation manner, the determining, by the electronic device, whether the antenna receiving signal of the electronic device meets a preset signal weak condition according to the AGC gear of the electronic device, the AGC gain of the electronic device, or the signal strength value of the electronic device may include: when the AGC gear of the electronic equipment is smaller than or equal to a preset gear, determining that the strength of an antenna receiving signal of the electronic equipment does not meet the preset signal weak condition; when the AGC gear of the electronic equipment is larger than a preset gear, determining that the strength of an antenna receiving signal of the electronic equipment meets the preset signal weak condition; when the AGC gain of the electronic equipment is larger than or equal to the preset gain, determining that the strength of an antenna receiving signal of the electronic equipment does not meet the preset signal weak condition; when the AGC gain of the electronic equipment is smaller than the preset gain, determining that the intensity of an antenna receiving signal of the electronic equipment meets the preset signal weak condition; when the signal intensity value of the electronic equipment is larger than or equal to the preset signal intensity value, determining that the intensity of the antenna receiving signal of the electronic equipment does not meet the preset signal weak condition; when the signal intensity value of the electronic equipment is smaller than the preset signal intensity value, determining that the intensity of the antenna receiving signal of the electronic equipment meets the preset signal weakness condition. In this way, the magnitude relation between the AGC gear, AGC gain or signal intensity value and the preset value of the electronic equipment is judged, so that the strength of the antenna receiving signal of the electronic equipment can be specifically determined, and the frame rate is limited when the signal is weak.

In a possible implementation manner, before the electronic device determines whether the antenna receiving signal of the electronic device meets the preset signal weak condition according to the AGC gear of the electronic device, the AGC gain of the electronic device, or the signal strength value of the electronic device, the method may further include: the electronic equipment judges whether a preset function of the first application is in use or not; the preset function is a function which needs to use an antenna to receive signals; when the preset function of the first application is in use, the electronic device acquires an AGC gear of the electronic device, an AGC gain of the electronic device, or a signal strength value of the electronic device. Therefore, the electronic equipment can improve the network communication experience by limiting the frame rate under the specific function, and optimize the power consumption of the electronic equipment. On the premise of not increasing the cost, the interference on the antenna receiving signals can be reduced, and the wireless performance of the electronic equipment is improved.

In a possible implementation manner, when the preset function of the first application is in use, the electronic device obtains an AGC gear of the electronic device, an AGC gain of the electronic device, or a signal strength value of the electronic device, which may include: when the preset function of the first application is in use, the electronic equipment judges whether the electronic equipment is displaying an interface of a preset type of the first application; when the electronic device is displaying the interface of the preset type of the first application, the electronic device obtains an AGC gear of the electronic device, an AGC gain of the electronic device or a signal strength value of the electronic device. In this way, the electronic device optimizes the display frame rate of the specific application scene, so that the influence of limiting the frame rate on the visual experience of the user can be reduced, the electronic device limits the frame rate in the application scene which is insensitive to the screen refresh rate by the user, and the user experience is improved.

In one possible implementation manner, the time interval between the second time and the third time is greater than or equal to a preset duration; and locking the frame rate of the electronic equipment to be a second frame rate within a preset duration from the second moment. Thus, the electronic device can lock the screen refresh rate at a lower frame rate for a preset period of time, thereby reducing interference.

In one possible implementation manner, the time interval between the second time and the third time is smaller than a preset duration; if the intensity of the antenna receiving signal of the electronic equipment meets the preset signal weak condition between the second moment and the third moment, the frame rate of the electronic equipment is the second frame rate; if the intensity of the antenna receiving signal of the electronic equipment does not meet the preset signal weak condition, the frame rate of the electronic equipment is the third frame rate. Therefore, the electronic equipment does not set the preset duration, the strength of the antenna received signal can be judged more timely, the frame rate of the weak signal is adjusted in real time, and the wireless performance is improved.

In a possible implementation manner, if the foreground of the electronic device switches out of the first application, or the first application does not use the preset function, the frame rate of the electronic device is adjusted to a fourth frame rate, where the fourth frame rate is greater than the second frame rate, and the fourth frame rate is equal to the first frame rate, or the fourth frame rate is unequal to the first frame rate. Therefore, when the foreground of the electronic equipment is switched out of the first application or the first application does not use the preset function, the electronic equipment can cancel the frame rate limitation in time, so that the visual effect of screen display corresponding to other applications is not affected, and the normal use of an interface of the electronic equipment is ensured.

Detailed Description

In order to facilitate the clear description of the technical solutions of the embodiments of the present application, the following simply describes some terms and techniques involved in the embodiments of the present application:

1. Command screen: the command screen may have a separate memory for caching data. When the host (or motherboard, chip, etc.) transmits data information to the command screen, the data information may be stored in the cache. The command screen can acquire data information from the cache and display an interface.

2. FPC: the flexible printed circuit board (flexible printed circuit board, FPC) is a printed circuit board made of a soft material such as a material that can be folded or bent. The FPC can be used for connecting the command screen with a printed circuit board (printed circuit board, PCB), so that current in the circuit can flow, and specific functions of the circuit are realized.

3. MIPI: the mobile industry processor interface (mobile industry processor interface, MIPI) can be used to transfer data at high speeds, standardizing interfaces within electronic devices, thereby reducing design complexity, power consumption, etc. of electronic devices.

4. Vsync frame synchronization technique: (VERTICAL SYNC, vsync) frame synchronization techniques mean that a screen (e.g., command screen) can read and render first frame data from a front buffer, and after the second frame data is calculated by a central processing unit (central processing unit, CPU), can be placed in a rear buffer and wait for a Vsync signal; after the command screen finishes rendering the first frame data, the command screen can send out a Vsync signal, and the CPU can copy the second frame data buffered later to the front buffer after receiving the Vsync signal; meanwhile, the command screen can continue drawing the second frame data, and the CPU can calculate the next frame data and cycle and reciprocate. That is, the Vsync frame synchronization technique may enable the command screen to control data exchange, so that the command screen may correctly display a picture to a user during drawing.

5. Screen refresh rate: referring to the number of screen refreshes in one second, for example, the screen refresh rate of an Android phone may be 60Hz, that is, 60 screen refreshes per second. It is understood that the screen refresh rate may be different for interfaces of different electronic devices or interfaces of different applications.

6. Frame rate: (frame per sconds, FPS) refers to the number of frames the CPU synthesizes in one second, e.g., 60FPS, which is the one second synthesis of 60 frames.

7. And (3) GNSS: a global positioning navigation system (global navigation SATELLITE SYSTEM, GNSS) may provide navigation information such as three-dimensional position, velocity, and/or precise timing with high accuracy. GNSS may include global positioning systems (global positioning system, GPS), beidou satellite navigation systems (beidou navigation SATELLITE SYSTEM, BDS), galileo satellite navigation systems (galileo satellite navigation system, galileo), and so on.

8. AGPS: an assisted global positioning system (assisted global positioning system, AGPS) can perform positioning in combination with positioning information of a mobile-operated network base station while receiving positioning signals through satellites. That is, the electronic device may be located by downloading auxiliary location information through the mobile network. It is to be understood that if AGPS is located only by the location information of the network base station that is operated by the mobile, AGPS may also be referred to as purely assisted location.

Fig. 2 is a software configuration block diagram of an electronic device according to an embodiment of the present application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun rows (Android runtime) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages. As shown in fig. 2, the application package may include applications such as telephone, music, calendar, camera, game, memo, video, and the like. Applications may include system applications and three-way applications.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a resource manager, a notification manager, a content provider, a view system, and the like.

The window manager is used for managing window programs. The window manager may obtain the display screen size, determine if there is a status bar, lock screen, touch screen, drag screen, intercept screen, etc.

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction.

Such as prompting text messages in status bars, sounding prompts, vibrating electronic devices, flashing indicator lights, etc.

The content provider is used for realizing the function of data sharing among different application programs, allowing one program to access the data in the other program, and simultaneously ensuring the safety of the accessed data.

The view system may be responsible for interface rendering and event handling for the application.

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

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like. For example, in the embodiment of the present application, the virtual machine may be used to perform functions such as location information acquisition, application type determination, frame rate locking, etc. in the embodiment of the present application.

This is because the electronic device may also need to perform interface display at a certain frame rate when implementing functions such as positioning, GPS navigation, voice call, etc. based on the antenna. When the electronic equipment displays an interface, the electronic equipment needs to transmit data in the CPU to a screen side based on a high-speed electronic device and an MIPI protocol, and the larger the frame rate is, the more frequent the data transmission is.

However, the frequent transmission data of the high-speed electronic device can radiate strong high-frequency noise to the outside, and the high-frequency noise can be transmitted to the antenna through some coupling circuits in the electronic device, so that the bottom noise of the antenna is raised, the sensitivity of a received signal is reduced, and the communication capability of the electronic device is further deteriorated.

For example, as shown in fig. 3, a signal received by the electronic device through the antenna may be transmitted to the CPU through the communication module, the radio frequency module, the Modem baseband module, and the like. When the electronic device performs screen display, the high-speed electronic device can transmit data in the CPU to the screen side through the MIPI protocol.

In the process of transmitting data through the MIPI protocol, assuming that the interval time of a high-speed data packet transmitted by the MIPI protocol is T and the frame rate of screen refreshing is FPS, the following formula is satisfied:

T＝1/FPS

it will be appreciated that when the frame rate (FPS) of the screen refresh is greater, the shorter the time interval (T) in which the MIPI protocol transmits data, the more frequent the corresponding data stream transmission, the more noise is radiated externally and therefore the greater the interference with the antenna received signal, resulting in a degraded communication network for the user when using the electronic device.

For electronic equipment using a command screen, the refresh rate of the command screen is high, the screen area is large, and the FPC wiring is longer, so that the problem of interference of antenna receiving signals is more easily caused.

In some implementations, the electronic device may reduce interference of externally radiated noise on the antenna receive signal by adjusting the frequency at which the MIPI protocol transmits data. However, adjusting the frequency of the MIPI protocol transmission data still causes interference to the antenna received signal, degrading the performance of the entire rf module and the communication module.

In view of this, according to the frame rate control method provided by the embodiment of the application, when the electronic device detects that the signal intensity received by the antenna is weak, the electronic device can reduce the transmission of the data stream by reducing the frame rate of screen refreshing, thereby reducing the noise of external radiation and reducing the interference to the signal received by the antenna.

It can be appreciated that, since reducing the frame rate affects the visual effect of the screen display, the frame rate control method provided by the embodiment of the present application may be performed in a scene where the user is insensitive to the screen refresh rate, that is, in a scene where the user has a low requirement for the visual effect of the screen display. For example, a scenario where the user is insensitive to the screen refresh rate may include: navigation scenarios, voice call scenarios, etc.

The frame rate control method according to the embodiment of the present application will be described in detail below taking a navigation scene as an example.

Fig. 4 shows a frame rate control method according to an embodiment of the present application. According to the method, based on the Vsync frame synchronization technology, when the electronic equipment detects that signals received by the antenna are poor and GPS positioning is used, the electronic equipment can limit the frame rate, so that the frame rate is limited to a lower value within a preset time, interference on the signals received by the antenna is reduced, and the wireless performance is improved. The specific method comprises the following steps:

s401, acquiring positioning information.

When an application needs to use GPS positioning, a request to use GPS positioning needs to be sent to the electronic device. For example, the application may apply for GPS positioning rights to the electronic device, and when the application obtains the GPS positioning rights, the application may further obtain GPS positioning information. Accordingly, the electronic device may determine whether the application uses GPS positioning by acquiring the positioning information, and specific determination of whether to use GPS positioning may refer to step S402.

S402, whether GPS positioning is used or not.

In one possible implementation of determining whether to use GPS positioning, the electronic device may determine whether the current GPS positioning is on through the GPS PROVIDER field of the position location manager LocationManager, where the GPS PROVIDERGPS field may represent that positioning information is acquired through GPS satellites. For example, if the electronic device determines LocationManager that the gps_provider is true, which indicates that the GPS positioning is turned on, step S403 is executed; if the electronic device determines LocationManager that the gps_provider is false, which indicates that the GPS positioning is not on and does not need to further limit the frame rate, step S409 is performed. The embodiment of the application is not limited to a mode of judging whether to use GPS positioning.

It should be noted that, in the embodiment of the present application, the application applies for the GPS positioning authority, but does not process the scenario that the GPS satellite is not used to acquire the positioning information, and in this scenario, the application may use a pure assisted positioning mode to acquire the GPS positioning information, that is, the application may perform positioning by using the positioning information of the network base station operated by the mobile. In a possible implementation, the electronic device may determine whether pure assisted positioning is used by determining a network_provider field of LocationManager, where the network_provider field may be used to indicate that positioning information is obtained through a base station or Wi-Fi. For example, if the electronic device determines LocationManager that NETWORK_PROVIDER is true, it indicates that pure assisted positioning is enabled; if the electronic device determines LocationManager that NETWORK_PROVIDER is false, the pure auxiliary positioning is not started. The embodiment of the application is not limited in the way of judging whether the pure auxiliary positioning is started or not.

It will be appreciated that the GPS positioning may be replaced by other positioning systems, such as a GNSS system, a beidou satellite navigation system, a galileo satellite navigation system, etc., and embodiments of the present application are not limited.

S403, whether the display interface is a navigation interface or not.

In the embodiment of the application, the electronic equipment can judge whether the display interface is the interface of the navigation application by acquiring the application running in the current foreground.

In a possible implementation, the electronic device may obtain the application being run in the foreground by using the usage statistics function. Specifically, the electronic device may obtain an application list used by the user through the service UsageStatsManager for counting the application use condition, and sort the applications in the application list according to the latest use time, so as to obtain the application running in the current foreground.

After the electronic device obtains the application running in the current foreground, it may determine whether the application is a navigation application based on the identification information of the application and the like. The identification information of the application may include an application package name, or an application identification (application identification, appId), or the like. The embodiment of the application is not limited in the manner of judging whether the display interface is a navigation interface.

If the electronic device determines that the display interface is a navigation interface, executing step S404; if the electronic device determines that the display interface is not the navigation interface, step S409 is executed.

It should be noted that, step S402 and step S403 are used to define a navigation application scenario using the positioning system. Therefore, the order of step S402 and step S403 may not be limited, that is, the electronic device may determine whether the current display interface is a navigation interface, and then determine whether to use the positioning system.

S404, reading an AGC gear or an AGC gain.

When the signal strength received by the antenna of the electronic device is weak, an automatic gain control (automatic gain control, AGC) module in the radio frequency module of the electronic device may amplify the signal. The AGC module may have a number of gears and may correspond to different gain values. For example, the AGC gear may include 1-15 gears, which may correspond to 0db-30db gains, respectively. It should be understood that the weaker the signal received by the antenna, the more signals need to be compensated, and the larger the gear or gain corresponding to the AGC module, for example, when the AGC gear is above 12, the weaker the signal strength received by the corresponding antenna can be considered, and further, the weaker signal can be amplified by the AGC module.

In a possible implementation, the electronic device may read the AGC shift or AGC gain through the radio frequency module. After the AGC shift or AGC gain is read, step S405 may be performed.

S405, whether the AGC gear is higher than a first limit value.

In the embodiment of the present application, step S405 is used to determine whether the signal is a scene of a weak field signal, and the first limit value may be a limit value of an AGC gear for determining the signal strength, for example, the first limit value may be 12 gears. For example, when the AGC range is greater than 12, which indicates that the signal received by the electronic device is weak and that frame rate limitation is required for the navigation interface, step S406 may be performed. When the AGC gear is less than or equal to 12 th gear, it indicates that the signal received by the electronic device is strong, and the frame rate of the navigation interface is not required to be limited, step S409 may be executed. The first limit value may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the first limit value.

The first limit value may be a limit value of AGC gain for determining the signal strength, and the first limit value may be 20db, for example. For example, when the AGC gain is greater than 20db, which indicates that the signal received by the electronic device is weak, the frame rate limitation on the navigation interface is required, step S406 may be performed. When the AGC gain is less than or equal to 20db, it indicates that the signal received by the electronic device is strong, and the frame rate of the navigation interface is not required to be limited, step S409 may be performed.

It can be appreciated that the embodiment of the application can also judge whether the scene is a weak field signal or not according to the signal strength value. In a possible implementation, the electronic device may read the signal strength value through a Modem baseband module. For example, the electronic device may determine whether the signal strength value is below a third limit. For example, when the signal strength value is smaller than the third limit value, which indicates that the signal received by the electronic device is weak and that the frame rate limitation is required for the navigation interface, step S406 may be performed. When the signal strength value is greater than or equal to the third limit value, it indicates that the signal received by the electronic device is stronger, and the frame rate of the navigation interface is not required to be limited, step S406 may be executed. The third limit value may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the third limit value.

S406, locking the frame rate in the first preset duration to enable the frame rate not to be higher than a second limit value.

In the embodiment of the present application, the first preset duration may be a shorter duration, for example, the first preset duration may be 1 minute. In the first preset duration, the electronic device can lock the screen refresh rate of the command screen at a lower frame rate, so that interference can be reduced. The first preset duration may be set by the electronic device in a user-defined manner, and the embodiment of the present application is not limited to a specific value of the first preset duration.

The second limit may be a limit on the frame rate, for example, the second limit may be 5FPS, that is, the electronic device may control the screen refresh rate of the command screen to be refreshed 5 times a second, or less than 5 times a second. The second limit value may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the second limit value.

After the first preset time period, step S407 may be performed.

S407, the positioning request terminates or switches out the application.

The method for determining whether the GPS positioning is on in step S402 can be referred to for the electronic device to determine that the positioning request is terminated, which is not described in detail. If the GPS positioning is started, the positioning request is not terminated; if the GPS positioning is not started, the positioning request is stopped.

The method for the electronic device to judge that the application is switched out may refer to the application that is currently running in the previous step S403, which is not described in detail. If the foreground application is the navigation application, indicating that the navigation application is not switched out; if the foreground application is not the navigation application, the switching out of the navigation application is described.

After the first preset duration, if the positioning request is terminated, or the navigation application is switched out, executing step S408; if the positioning request is not terminated and the navigation application is not switched out, step S404 is executed.

It will be appreciated that if the positioning request is not terminated and the navigation application is not switched out, the electronic device may periodically read the AGC shift or AGC gain and loop through steps S404 to S407. For example, the electronic device may read the AGC shift or AGC gain once for 1 second and perform steps S404 to S407. The period for reading the AGC shift or the AGC gain can be set by the electronic device in a self-defined manner, and the embodiment of the application does not limit the specific period setting for acquiring the positioning signal intensity.

S408, releasing the frame rate limit.

The electronic device may remove the frame rate limit when the positioning request terminates, or switches out of the navigation application. That is, when the positioning request is terminated, or the navigation application is switched out, the electronic device may not receive the signal using the antenna, so that the antenna is not affected by the internal transmission data of the electronic device, and the electronic device does not need to lock the refresh rate of the screen at a lower frame rate. After the frame rate limit is released, the electronic device can flexibly adjust the frame rate based on the actual application scene.

In a possible implementation, the electronic device may modify the refresh rate of the screen to a frame rate value that is greater than the second limit, e.g., the electronic device may modify the refresh rate of the screen to a value prior to the lock frame rate. The screen refresh rate after the frame rate limitation is released can be set by the electronic device in a self-defined way, and the specific value of the screen refresh rate is not limited by the embodiment of the application.

S409, not limiting the frame rate.

In the embodiment of the application, when the electronic device judges that the frame rate does not need to be limited, the electronic device can periodically and repeatedly execute the S404-S409 frame rate control method in the embodiment of the application on the premise that the positioning request is not terminated and the foreground application is the navigation application. For example, the electronic device may perform the frame rate control method once in 1 second. The period of repeatedly executing the frame rate control method may be set by the electronic device in a self-defining manner, and the embodiment of the application is not limited.

Fig. 5 shows another frame rate control method according to an embodiment of the present application. The method comprises the following steps:

S501, acquiring positioning information.

When an application needs to use GPS positioning, a request to use GPS positioning needs to be sent to the electronic device. For example, the application may apply for GPS positioning rights to the electronic device, and when the application obtains the GPS positioning rights, the application may further obtain GPS positioning information. Accordingly, the electronic device may determine whether the application uses GPS positioning by acquiring the positioning information, and specific determination of whether to use GPS positioning may refer to step S502.

S502, whether GPS positioning is used or not.

In the embodiment of the present application, whether the GPS positioning is turned on may refer to the method for determining whether the GPS positioning is turned on in step S402 in the embodiment corresponding to fig. 4, which is not repeated. If the GPS positioning is started, executing step S503; if the GPS positioning is not on, step S509 is executed.

S503, whether the display interface is a navigation interface or not.

In the embodiment of the application, the electronic equipment can judge whether the display interface is the interface of the navigation application by acquiring the application running in the current foreground. The method for determining whether the display interface is the navigation interface may refer to the method for acquiring the currently running application in step S403 in the embodiment corresponding to fig. 4, which is not described herein.

If the display interface of the electronic device is a navigation interface, executing step S504; if the display interface of the electronic device is not the navigation interface, step S509 is executed.

It will be appreciated that steps S502 and S503 are used to define a navigation application scenario in which the positioning system is used. Therefore, the order of step S502 and step S503 may not be limited, that is, the electronic device may determine whether the current display interface is a navigation interface, and then determine whether to use the positioning system.

S504, acquiring the positioning signal intensity.

The electronic equipment can judge the strength of the signal by reading the signal strength value through the Modem baseband module. The signal strength value may be represented by a signal-to-noise ratio (carrier noise ratio, CN 0), where CN0 may be a ratio of satellite signal power received by the antenna to noise, where noise may include thermal noise, as well as interference noise. As can be seen from CN0, when the satellite signal power is constant, the larger the noise is, the larger the interference to the antenna is, and the worse the received signal is; the smaller the noise, the less the interference to the antenna and the better the received signal, so reducing the frame rate can reduce the noise generated when the MIPI protocol transmits data, thereby enhancing the quality of the received signal by the antenna.

After the electronic device reads the signal strength value, step S505 may be performed.

S505, whether the positioning signal strength is lower than a third limit value.

In the embodiment of the present application, step S505 is used to determine whether the scene is a weak field signal, and the third limit value may be a signal strength limit value for determining the signal strength, and the third limit value may be a value of CN 0. Illustratively, the value of CN0 may be 40. When CN0 is smaller than 40, which indicates that the signal received by the electronic device is weak and that frame rate limitation is required for the navigation interface, step S506 may be performed. When CN0 is greater than or equal to 40, which indicates that the signal received by the electronic device is strong, and the frame rate of the limited navigation interface is not needed, step S509 is executed. The third limit value may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the third limit value.

It can be understood that the electronic device can also judge the strength of the signal by reading the AGC shift or AGC gain through the radio frequency module. The judgment of the signal strength by the AGC shift or the AGC gain can refer to the description in step S405 of the embodiment corresponding to fig. 4, and will not be repeated.

S506, continuously locking the frame rate to enable the frame rate not to be higher than the second limit value.

In the embodiment of the application, when the electronic equipment judges that the received signal is weak, the electronic equipment can continuously lock the screen refresh rate of the command screen on the lower second limit frame rate, so that the interference can be reduced. The second limit may be a limit value for the frame rate, for example, the second limit value may be 5FPS, that is, the electronic device may control the screen refresh rate of the command screen to be refreshed 5 times a second. The second limit value may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the second limit value.

S507, the positioning request terminates or switches out the application.

The method for determining whether the GPS positioning is on in step S402 of the embodiment corresponding to fig. 4 may be referred to for the electronic device to determine that the positioning request is terminated, which is not described herein. If the GPS positioning is started, the positioning request is not terminated; if the GPS positioning is not started, the positioning request is stopped.

The method for determining that the application is being switched by the electronic device may refer to the determination in step S403 in the embodiment corresponding to fig. 4 to obtain the application currently running in the foreground is not described herein. If the foreground application is the navigation application, indicating that the navigation application is not switched out; if the foreground application is not the navigation application, the navigation application is switched out.

If the positioning request is terminated, or the navigation application is switched out, executing step S508; if the positioning request is not terminated and the navigation application is not switched out, step S504 is performed.

It may be appreciated that if the positioning request is not terminated and the navigation application is not switched out, the electronic device may periodically acquire the positioning signal strength and perform steps S504 to S507 in a loop. For example, the electronic device may acquire the positioning signal strength once for 1 second and perform steps S504 to S507. The period for acquiring the positioning signal strength can be set by the electronic equipment in a self-defined manner, and the embodiment of the application does not limit the specific period setting for acquiring the positioning signal strength.

S508, releasing the frame rate limit.

The electronic device may remove the frame rate limit when the positioning request terminates, or switches out of the navigation application. The specific manner of releasing the frame rate limitation may refer to the related description in step S408 in the embodiment corresponding to fig. 4, which is not repeated.

S509, the frame rate is not limited.

In the embodiment of the application, when the electronic equipment judges that the frame rate does not need to be limited, the electronic equipment can periodically and repeatedly execute the frame rate control method of the embodiment of the application on the premise that the positioning request is not terminated and the foreground application is the navigation application. For example, the electronic device may perform the frame rate control method once in 1 second. The period of repeatedly executing the frame rate control method may be set by the electronic device in a self-defining manner, and the embodiment of the application is not limited.

The frame rate control method according to the embodiment of the present application will be described in detail by way of specific embodiments. The following embodiments may be combined with each other or implemented independently, and the same or similar concepts or processes may not be described in detail in some embodiments.

Specifically, fig. 6 is a schematic diagram of frame rate control according to an embodiment of the present application. The specific steps can be as follows:

S601, at a first moment, a foreground of the electronic equipment runs a first application, the strength of an antenna receiving signal of the electronic equipment does not meet a preset signal weak condition, and the frame rate of the electronic equipment is a first frame rate.

In the embodiment of the present application, the first time may be a time when the intensity of the signal received by the antenna of the electronic device is strong, and it may also be understood that, at the first time, the electronic device does not need to perform frame rate limitation on the first application.

The first application may be any application running in the foreground of the electronic device. In a possible implementation, the first application may be an application that is insensitive to the screen refresh rate for some users in order for the electronic device not to affect the visual effect of the screen display after reducing the frame rate. For example, the application insensitive to the screen refresh rate of the user may be a navigation application in the above embodiment, or may be a voice call application, etc., and the embodiment of the present application is not limited to a specific first application.

The first frame rate may be a frame rate before the frame rate is not limited when the first application is run in the foreground of the electronic device. The first frame rate may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the first frame rate.

S602, continuously running a first application at a second moment by a foreground of the electronic equipment, wherein the strength of a signal received by an antenna of the electronic equipment meets a preset signal weakness condition, and the frame rate of the electronic equipment is a second frame rate, wherein the second frame rate is smaller than the first frame rate, and the second moment is later than the first moment.

In the embodiment of the present application, the second time may be a time when the intensity of the signal received by the antenna of the electronic device is weaker, and it may also be understood that, at the second time, the electronic device needs to perform frame rate limitation on the first application.

The second frame rate may be a frame rate at which the frame rate is limited when the foreground of the electronic device is running the first application. Thus, the second frame rate after being limited may be less than the first frame rate before being limited. Illustratively, the second frame rate may refer to the description related to the second limit value in step S406 of the embodiment corresponding to fig. 4, for example, the second frame rate may be a value less than or equal to the second limit value (e.g., 5 FPS). The second frame rate may be set by the electronic device in a customized manner, and the embodiment of the present application is not limited to a specific value of the second frame rate.

And S603, continuously running the first application at a third moment by a foreground of the electronic equipment, wherein the strength of a signal received by an antenna of the electronic equipment does not meet a preset signal weakness condition, the frame rate of the electronic equipment is a third frame rate, the third frame rate is larger than the second frame rate, the third frame rate is equal to the first frame rate, or the third frame rate is unequal to the first frame rate, and the third moment is later than the second moment.

In the embodiment of the application, the third time may be a time when the antenna of the electronic device receives a stronger signal, and the electronic device may release the frame rate limitation on the first application. The specific manner of releasing the frame rate limitation may refer to the related description in step S408 in the embodiment corresponding to fig. 4, which is not repeated.

The third frame rate may be a frame rate of the electronic device after the frame rate restriction is released from the first application when the foreground of the electronic device runs the first application. Therefore, the third frame rate after the frame rate restriction is released may be greater than the second frame rate. It is understood that the third frame rate may or may not be equal to the first frame rate. The third frame rate may be set by the electronic device in a self-defining manner, and the embodiment of the present application is not limited to a specific value of the third frame rate.

In the embodiment of the application, when the electronic equipment detects that the intensity of the signal received by the antenna is weaker, the electronic equipment can limit the frame rate of the application running in the foreground to reduce the interference on the signal received by the antenna, so that the communication network is improved when the electronic equipment is used by a user, and the user experience is improved.

Optionally, on the basis of the embodiment corresponding to fig. 6, the method further includes: the electronic equipment determines whether an antenna receiving signal of the electronic equipment meets the preset signal weakness condition according to the AGC gear of the electronic equipment, the AGC gain of the electronic equipment or the signal intensity value of the electronic equipment.

In the embodiment of the present application, regarding the acquisition of the AGC gear, the AGC gain, or the signal strength value of the electronic device and the value range, reference may be made to the description related to step S405 in the embodiment corresponding to fig. 4 and the description related to step S505 in the embodiment corresponding to fig. 5, which are not repeated. The embodiment of the application is not limited to determining whether the antenna receiving signal of the electronic device meets the preset signal weak condition. By judging the strength of the signal received by the antenna, the frame rate of the electronic equipment is limited when the signal is weak, so that the interference on the signal received by the antenna can be reduced.

The preset gear can be set by the electronic device in a self-defined manner, and the embodiment of the application is not limited to the specific value of the preset gear.

The electronic device may also determine whether the antenna received signal meets the preset signal weak condition by determining the relationship between the AGC gain and the preset gain, where the preset gain may be a threshold value of the AGC gain for determining the signal weak, and the preset gain may be, for example, the first threshold value (e.g. 20 db) in step S405 in the embodiment corresponding to fig. 4. The preset gain may be set by the electronic device in a self-defined manner, and the embodiment of the present application is not limited to a specific value of the preset gain.

The preset signal strength value may be set by the electronic device in a self-defined manner, and the embodiment of the present application is not limited to a specific value of the preset signal strength value.

In the embodiment of the application, the strength of the antenna receiving signal of the electronic equipment can be specifically determined by judging the AGC gear, AGC gain or the relation between the signal strength value and the preset value of the electronic equipment, so that the frame rate is limited when the signal is weak by the electronic equipment, and the interference on the antenna receiving signal can be reduced.

Optionally, on the basis of the embodiment corresponding to fig. 6, before determining, by the electronic device according to the AGC gear of the electronic device, the AGC gain of the electronic device, or the signal strength value of the electronic device, whether the antenna receiving signal of the electronic device meets a preset signal weak condition, the method may further include: the electronic equipment judges whether a preset function of the first application is in use or not; the preset function is a function which needs to use an antenna to receive signals; when the preset function of the first application is in use, the electronic device acquires an AGC gear of the electronic device, an AGC gain of the electronic device, or a signal strength value of the electronic device.

In the embodiment of the present application, the function of receiving signals by using the antenna may be the GPS positioning function in the embodiment corresponding to fig. 4 or fig. 5, or may be a positioning function using other systems, or may be a function using Wi-Fi signals, 2G signals, 3G signals, 4G signals, or 5G signals. By way of example, the functions using Wi-Fi signals or 5G signals may include voice call functions, data upload or download functions, and the like. The function of receiving signals by using the antenna is particularly used, and the embodiment of the application is not limited.

The electronic equipment can improve the network communication experience by limiting the frame rate under the specific function, and optimize the power consumption of the electronic equipment. On the premise of not increasing the cost, the interference on the antenna receiving signals can be reduced, and the wireless performance of the electronic equipment is improved.

Alternatively, on the basis of the embodiment corresponding to fig. 6, it may include: when the preset function of the first application is in use, the electronic equipment judges whether the electronic equipment is displaying an interface of a preset type of the first application; when the electronic device is displaying the interface of the preset type of the first application, the electronic device obtains an AGC gear of the electronic device, an AGC gain of the electronic device or a signal strength value of the electronic device.

In the embodiment of the present application, the preset type of interface may be a navigation application interface in the embodiment corresponding to fig. 4 or fig. 5, or may be a navigation application interface using other positioning systems, or may be an application interface insensitive to the screen refresh rate for some users. The specific preset type of interface is not limited in the embodiment of the present application.

In a possible implementation of determining the preset type interface, the electronic device may add identification information to the application interface insensitive to the screen refresh rate by the user, and by limiting the frame rate of the application interface containing the identification information, the visual effect that the display of the application screen is not affected after the frame rate is reduced is satisfied.

In another possible implementation of determining the preset type interface, the electronic device may predefine an application interface insensitive to the screen refresh rate to the white list, and further limit the frame rate of the foreground application interface by determining that the foreground application interface is an interface of the preset type in the white list.

Of course, the electronic device may also determine, in real time, whether the interface displayed in the foreground is a preset type of interface based on some algorithms, and the embodiment of the present application is not limited specifically.

The electronic equipment optimizes the display frame rate of the specific application scene, so that the influence of limiting the frame rate on the visual experience of the user can be reduced, the electronic equipment limits the frame rate in the application scene which is insensitive to the screen refresh rate by the user, and the user experience is improved.

Alternatively, on the basis of the embodiment corresponding to fig. 6, it may include: the time interval between the second time and the third time is greater than or equal to the preset duration; and locking the frame rate of the electronic equipment to be a second frame rate within a preset duration from the second moment.

In the embodiment of the present application, the preset duration may refer to the description related to the first preset duration (e.g. 1 minute) in step S406 in the embodiment corresponding to fig. 4, which is not repeated. The electronic device may lock the screen refresh rate at a lower frame rate for a preset duration, thereby reducing interference.

Alternatively, on the basis of the embodiment corresponding to fig. 6, it may include: the time interval between the second time and the third time is smaller than the preset duration; if the intensity of the antenna receiving signal of the electronic equipment meets the preset signal weak condition between the second moment and the third moment, the frame rate of the electronic equipment is the second frame rate; if the intensity of the antenna receiving signal of the electronic equipment does not meet the preset signal weak condition, the frame rate of the electronic equipment is the third frame rate.

In the embodiment of the present application, the time interval between the second time and the third time being smaller than the preset time period may be understood as the frame rate control method in the embodiment corresponding to fig. 5, that is, the electronic device may not set the preset time period for the frame rate limitation, and the electronic device may periodically determine whether the frame rate limitation needs to be performed, for example, the electronic device may determine once in 1 second. For a specific judgment manner, reference may be made to the description related to step S507 or step S509 in the embodiment corresponding to fig. 5, which is not repeated. The electronic equipment does not set the preset duration, so that the strength of the antenna received signal can be judged more timely, the frame rate of the weak signal is adjusted in real time, and the wireless performance is improved.

Alternatively, on the basis of the embodiment corresponding to fig. 6, it may include: if the foreground of the electronic device switches out the first application, or the first application does not use the preset function, the frame rate of the electronic device is adjusted to be a fourth frame rate, wherein the fourth frame rate is greater than the second frame rate, and the fourth frame rate is equal to the first frame rate, or the fourth frame rate is unequal to the first frame rate.

In the embodiment of the present application, the fourth frame rate may be the frame rate after the electronic device releases the frame rate limitation under the condition corresponding to step S408 of the embodiment corresponding to fig. 4 and step S508 of the embodiment corresponding to fig. 5. The fourth frame rate may be a frame rate of the electronic device when the foreground runs other applications (not the first application), and it is understood that the fourth frame rate may or may not be equal to the first frame rate (or the third frame rate). The fourth frame rate may be set by the electronic device in a customized manner, and the embodiment of the present application is not limited to a specific value of the fourth frame rate.

When the foreground of the electronic equipment is switched out of the first application or the first application does not use the preset function, the electronic equipment can cancel the frame rate limitation in time, so that the visual effect of screen display corresponding to other applications used by a user is not influenced, and the normal use of an interface of the electronic equipment is ensured.
