Detailed ways

In the description of the embodiments of this application, words such as "such as" are used to represent examples, illustrations or illustrations. Any embodiment or design described as "such as" in the embodiments of the application is not to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "such as" is intended to present the relevant concept in a concrete way.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the description of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. It should be understood that in this application, "plurality" means two or more than two unless otherwise stated.

The existing technology provides a user terminal mode control method that can use high-speed rail private network cells deployed by operators to identify terminal scenarios. In the existing user terminal mode control method, when it is determined that the motion state of the terminal is the riding state, the high-speed flag (HighSpeedFlag is true) provided by the modem (Modem) is obtained, wherein the high-speed flag is LTE (Long Term Evolution, Long Term Evolution). Evolution) communication network format carries data. If the high-speed signs can be obtained continuously within the set time (such as within 30 seconds), the current status of the terminal is judged to be the riding status along the high-speed rail. Existing user terminal mode control methods rely on high-speed rail private network cells deployed by operators, which will result in the inability to identify high-speed rail scenarios under non-high-speed rail private networks. At the same time, only China Mobile's high-speed rail private network has been deployed in large quantities. China Telecom and China Unicom have not deployed high-speed rail private networks in large quantities, and they do not have the HighSpeedFlag logo. These will result in a low terminal scene recognition rate of existing user terminal mode control methods. In view of this, embodiments of this application propose a terminal scene identification method that does not rely on high-speed rail private network cells deployed by operators, thereby improving the terminal scene identification rate.

First, take the scenario of high-speed rail running on a high-speed rail line as shown in Figure 1 as an example to describe the application scenario of this application.

As shown in Figure 1, a high-speed rail runs on a high-speed rail line, and the high-speed rail line is covered by multiple cells for providing services to terminals moving on the high-speed rail line. The plurality of cells may include cellular cells covered by public base station signals, or may also include cellular cells covered by dedicated base station signals, that is, high-speed rail line public network cells, or may also include high-speed rail private network cells. Each cell is the area covered by a base station or a part of a base station (sector antenna). The plurality of cells may include cells supporting fourth generation (4G) access technology, such as cells supporting long term evolution (LTE) access technology; or may include cells supporting fifth generation (fifth generation) , 5G) access technology cells, such as new radio (NR) access technology cells; or, it may also include cells supporting multiple wireless technologies, such as cells supporting LTE technology and NR technology. It is also understood that multiple of the cells may also be cells suitable for future-oriented communication technologies. Among them, each cell corresponds to a unique cell ID.

High-speed rail lines can be divided into multiple high-speed rail line areas, and each high-speed rail line area can be covered by one or more cells. In Figure 1, the high-speed rail segment can be divided into six high-speed rail areas (high-speed rail area 1-high-speed rail area 6). Each of these six high-speed rail line areas can be covered by one or more cells. For example, high-speed rail line area 3 may be covered by cell 3 and cell 4. When the terminal passes through a certain high-speed railway line area, it can camp in a certain cell among one or more cells covering the high-speed railway line area. For example, in Figure 1, when passing through the high-speed rail area 3, the terminal can camp under the cell 3 covering the high-speed rail area 3. Therefore, the terminal can access the network. It can be understood that when the terminal passes through a certain high-speed rail line area, due to the high speed of the high-speed rail, etc., it may not switch to the cell covering the high-speed rail line area, that is, directly skip the cell covering the high-speed rail line area and switch to A community covering the next high-speed rail line area.

Figure 3 is a software structure block diagram of the terminal 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has clear roles and division of labor. The layers communicate through software interfaces. In some embodiments, the Android system is divided into five layers, from top to bottom: application layer, application framework layer, Android runtime (Android runtime, ART) and native C/C++ library, hardware abstraction layer (Hardware Abstract Layer, HAL) and the kernel layer.

The application layer can include a series of application packages.

As shown in Figure 3, the application package can include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, news and other applications.

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

As shown in Figure 3, the application framework layer can include window manager, content provider, view system, resource manager, notification manager, activity manager, input manager, etc.

The window manager provides window management service (Window Manager Service, WMS). WMS can be used for window management, window animation management, surface management, and as a transfer station for the input system.

Content providers are used to store and retrieve data and make this data accessible to applications. Data can include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

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

The resource manager provides various resources to applications, such as localized strings, icons, pictures, layout files, video files, etc.

The notification manager allows applications to display notification information in the status bar, which can be used to convey notification-type messages and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be notifications that appear in the status bar at the top of the system in the form of charts or scroll bar text, such as notifications for applications running in the background, or notifications that appear on the screen in the form of conversation windows. For example, text information is prompted in the status bar, a prompt sound is emitted, the terminal vibrates, and the indicator light flashes, etc.

The Activity Manager can provide Activity Management Service (AMS), which can be used for the startup, switching, and scheduling of system components (such as activities, services, content providers, and broadcast receivers) as well as the management and scheduling of application processes. .

The input manager can provide input management service (Input Manager Service, IMS). IMS can be used to manage system input, such as touch screen input, key input, sensor input, etc. IMS takes out events from the input device node and distributes the events to appropriate windows through interaction with WMS.

The Android runtime includes core libraries and Android runtime. The Android runtime is responsible for converting source code into machine code. The Android runtime mainly includes the use of ahead of time (ahead or time, AOT) compilation technology and just in time (just in time, JIT) compilation technology.

The core library is mainly used to provide basic Java class library functions, such as basic data structures, mathematics, IO, tools, databases, networks and other libraries. The core library provides APIs for users to develop Android applications.

Native C/C++ libraries can include multiple function modules. For example: surface manager (surface manager), media framework (Media Framework), libc, OpenGL ES, SQLite, Webkit, etc.

Among them, the surface manager is used to manage the display subsystem and provides the integration of 2D and 3D layers for multiple applications. The media framework supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc. OpenGL ES provides the drawing and manipulation of 2D graphics and 3D graphics in applications. SQLite provides a lightweight relational database for terminal 100 applications.

The hardware abstraction layer runs in user space, encapsulates the kernel layer driver, and provides a calling interface to the upper layer.

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.

The following is an example of the workflow of the terminal software and hardware based on capturing the 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 raw input events (including touch coordinates, timestamps of touch operations, and other information). Raw input events are stored at the kernel level. The application framework layer obtains the original input event from the kernel layer and identifies the control corresponding to the input event. Take the touch operation as a touch-click operation, and the control corresponding to the click operation is a camera application icon control 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 to capture the image through the camera. Still image or video.

As shown in Figure 5, when the application (such as audio and video application, news application, etc.) 501 is running in the application foreground, or when switching from the application background running to the application foreground, it will register the high-speed rail station with the terminal scene recognition device 502 Scene recognition. Therefore, the terminal scene recognition device 502 can determine the application program 501 as a target application registered with the scene event of the terminal entering the high-speed rail station. In Figure 5, when the terminal is controlled to enter the high-speed rail station scene, the terminal scene recognition device 502 will send the instruction information of the high-speed rail station scene caching strategy to the application program 501, and the application program 501 will determine the high-speed rail station scene according to the high-speed rail station scene. The instruction information of the cache policy performs the first cache operation. It is understandable that the application program 501 may also register scene recognition with the terminal scene recognition device 502 when it is installed, runs in the application background, or switches from the application foreground to the application background. This application does not limit this. It can be understood that the application program 501 can also cancel the registration of high-speed rail station scene recognition with the terminal scene recognition device 502, and this application does not limit this.

In some embodiments, when the application performs the first cache operation according to the scene notification of controlling the terminal to enter the high-speed rail station, the first cache operation prompt (as shown in Figure 6) can also be performed, thereby allowing the user to be aware of the high-speed rail station. Scene optimization is more perceptive. In Figure 6, the video application is performing the first caching operation. At this time, while the terminal is playing the video, the first prompt box pops up on the video interface. The first prompt box is used to prompt the user that the video application has enabled high-speed rail station scene optimization. In FIG. 6 , the first prompt box may be prompt 1, and the prompt 1 may be, for example, “High-speed rail station scene optimization has been started for you.” It can be understood that FIG. 6 is an example of the first prompt box, and this application does not limit the content and form of the first prompt box. It can be understood that the first prompt box may be displayed all the time when the first caching operation is performed, or may only be displayed for a few seconds. This application does not limit the display time of the first prompt box.

S405: Obtain the community fence information of the high-speed rail line.

In some embodiments, the cell fence information of the high-speed rail line is cellular cell fence information of the high-speed rail line. The cell fence information of the high-speed rail line may be a virtual boundary surrounded by all cells covering the geographical area of the high-speed rail line. The cell fence information of the high-speed rail line includes the identification (cell ID) of all cells covering the geographical area of the high-speed rail line. It can be understood that the cell fence information of the high-speed rail line can also be a virtual boundary surrounded by most of the cells covering the geographical area of the high-speed rail line, and this application is not limited to this.

In some embodiments, the community fence information of the high-speed rail line may also be the community fence information of the high-speed rail line in the geographical area where the terminal is currently located, such as the community fence information of the high-speed rail line in XX City.

In some embodiments, the cell fence information of the high-speed rail line may also be the cell fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located. Specifically, after step S403 and before step S404, the method further includes: determining the high-speed rail station where the terminal is currently located. The obtaining the cell fence information of the high-speed rail line may include obtaining the cell fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located. In some embodiments, the cell fence information of the high-speed rail line may also include path information of the high-speed rail line of the high-speed rail station where the terminal is currently located. For example, as shown in Figure 7, if the current high-speed rail station where the terminal is located is high-speed rail station A, then starting from high-speed rail station A, there are three routes, namely high-speed rail line L1 from high-speed rail station A to high-speed rail station B, high-speed rail station A High-speed rail line L2 to high-speed rail station C, and high-speed rail line L3 from high-speed rail station A to high-speed rail station D. Then, the path information of the high-speed rail line of the high-speed rail station where the terminal is currently located includes the path information of the high-speed rail line L1, the high-speed rail line L2, and the high-speed rail line L3, and the community fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located includes the community fence information of the high-speed rail line L1. Information, community fence information of high-speed rail line L2 and community fence information of high-speed rail line L3. If the current high-speed rail station where the terminal is located is high-speed rail station D, then high-speed rail station D is used as the starting point, including a total of 4 routes, including high-speed rail line L3 from high-speed rail station D to high-speed rail station A, and high-speed rail line L3 from high-speed rail station D to high-speed rail station E. L4, high-speed rail line L5 from high-speed rail station D to high-speed rail station F, and high-speed rail line L6 from high-speed rail station D to high-speed rail station G. Then, the path information of the high-speed rail line of the high-speed rail station where the terminal is currently located includes the path information of high-speed rail line L3, high-speed rail line L4, high-speed rail line L5, and high-speed rail line L6, and the community fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located includes the path information of high-speed rail line L3. Community fence information, community fence information for high-speed rail line L4, community fence information for high-speed rail line L5, and community fence information for high-speed rail line L6.

Among them, each high-speed rail line can be divided into multiple high-speed rail line areas, and each high-speed rail line area can be covered by one or more cells. For example, the high-speed rail line L1 can be divided into six high-speed rail line areas. These six high-speed rail line areas Each high-speed rail line area in can be covered by one or more cells. When the terminal is running on the high-speed rail line, the terminal may not switch to the cell covering the high-speed rail line area at the location due to the high speed of the high-speed rail. At the same location on the high-speed rail line, when the terminal passes by it for different times, the service cell where it resides may be different.

For ease of description, the following description will take the community fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located as an example.

The community fence information of the high-speed rail line can be shown in Table 2 below:

Table 2

It can be understood that Table 2 is an example of the community fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located. The community fence information of the high-speed rail line can also omit the high-speed rail station fence, or can also omit the high-speed rail line column. This application does not The content and form of community fence information for high-speed rail lines are limited.

In some embodiments, the cell fence information of the high-speed rail line may be preset in the terminal.

In some embodiments, the cell fence information of the high-speed rail line can be obtained from a cloud server.

S406: Determine whether the terminal leaves the high-speed rail station and enters the riding state. If the terminal leaves the high-speed rail station and the motion state enters the riding state, step S407 is executed. If the terminal leaves the high-speed rail station but the motion state of the terminal does not enter the riding state, step S409 is executed.

In some embodiments, since some people enter the high-speed rail station but may not leave the high-speed rail station (such as staff at the high-speed rail station, etc.), or although they leave the high-speed rail station but will not leave by car, it is necessary to distinguish whether the terminal leaves the high-speed rail station. And whether the motion state has entered the riding state.

In some embodiments, whether the terminal leaves the high-speed railway station is determined by determining whether the serving cell where the terminal currently resides continues to match the cell fence information of the high-speed railway station. If the service cell where the terminal currently resides continues to match the cell fence information of the high-speed rail station, it can be determined that the terminal has not left the high-speed rail station. If the service cell where the terminal currently resides does not continue to match the cell fence information of the high-speed rail station, it can be determined that the terminal has left the high-speed rail station.

In some embodiments, whether the motion state of the terminal enters the riding state can be determined based on the acceleration data sensed by the acceleration sensor in the terminal. Among them, when a high-speed train runs on a high-speed rail line, its acceleration is relatively stable. If the terminal is located on a high-speed rail, the acceleration perceived by the terminal will also be stable and within the motion acceleration range of the high-speed rail. If the acceleration data sensed by the acceleration sensor in the terminal is within the operating acceleration range of the high-speed rail, it can be determined that the terminal's motion state has entered the ride state; If the acceleration data sensed by the acceleration sensor in the terminal is outside the high-speed rail operating acceleration range, it can be determined that the motion state of the terminal has not entered the riding state.

In some embodiments, whether the motion state of the terminal enters the riding state can be determined based on the speed data sensed by the speed sensor in the terminal. Among them, the speed of the high-speed train after completing acceleration on the high-speed rail line will be within the operating speed range of the high-speed rail. Then if the speed data sensed by the speed sensor in the terminal is within the high-speed rail operating speed range, it can be determined that the terminal's motion state has entered the riding state; if the speed data sensed by the speed sensor in the terminal is outside the high-speed rail operating speed range, it can be determined The terminal's motion state has not entered the ride state.

In some embodiments, whether the motion state of the terminal enters the riding state can be determined based on the acceleration data sensed by the acceleration sensor and the speed data sensed by the speed sensor in the terminal. This application does not limit this.

S407: Determine whether the service cell where the terminal currently resides matches the cell fence information of the high-speed rail line. If the serving cell where the terminal currently resides matches the cell fence information of the high-speed rail line, step S408 is executed. If the serving cell where the terminal currently resides does not match the cell fence information of the high-speed rail line, step S409 is executed.

In some embodiments, since the operating status of ordinary vehicles (cars, etc.) is similar to that of high-speed rail, after the terminal sets off from the high-speed rail station and the motion state enters the riding state, it is necessary to further distinguish whether the terminal is currently on the high-speed rail or on the high-speed rail. If the terminal is located on an ordinary vehicle, it is necessary to determine whether the service cell where the terminal currently resides matches the cell fence information of the high-speed rail line.

In some embodiments, determining whether the serving cell where the terminal currently resides matches the cell fence information of the high-speed rail line may include: querying whether there is a second cell in the cell fence information of the high-speed rail line that matches the serving cell where the terminal currently resides. Target cell; if there is a second target cell matching the serving cell where the terminal currently resides in the cell fence information of the high-speed rail line, it is determined that the serving cell where the terminal currently resides matches the cell fence information of the high-speed rail line; if the If there is no second target cell that matches the service cell where the terminal currently resides in the cell fence information of the high-speed rail line, it is determined that the service cell where the terminal currently resides does not match the cell fence information of the high-speed rail line.

For example, if the serving cell where the terminal is currently camped is cell b7, it can be found in Table 1 that there is no second target cell matching the serving cell (cell b7) where the terminal is currently camped. At this time, it can be determined that the terminal is currently camped on. The remaining service community does not match the community fence information of the high-speed rail line.

In some embodiments, when a high-speed train runs on a high-speed rail line, its acceleration is relatively stable and its speed is relatively fast, and it can run a longer distance in a shorter period of time. In a short period of time, the terminals on the high-speed rail will also quickly move to different high-speed rail line areas. Since each high-speed rail line area can be covered by one or more cells, the terminal will quickly switch to different cells in a short period of time, and the service cell where the terminal currently resides will also change rapidly. Sometimes, due to the high speed of the high-speed rail, when the high-speed train passes through a certain high-speed rail line area, the terminal on the high-speed rail has not even switched to the community covering the high-speed rail line area, and the high-speed train has quickly moved to the next high-speed rail line area. On high-speed rail lines, there may be terminals that do not reside in a cell covering a certain high-speed rail line area. Then, determining whether the serving cell where the terminal currently resides matches the cell fence information of the high-speed rail line may include: querying whether there is a match between the cell fence information of the high-speed rail line and the serving cell where the terminal currently resides within a preset time. A preset number of third target cells; if there is a preset number of third target cells matching the serving cell where the terminal currently resides in the cell fence information of the high-speed rail line within the preset time, it is determined that the terminal is currently camped The remaining service cell matches the cell fence information of the high-speed rail line; if within the preset time there is no preset number of third target cells matching the service cell where the terminal currently resides in the cell fence information of the high-speed rail line, then It is determined that the service cell where the terminal currently resides does not match the cell fence information of the high-speed rail line.

For example, if within 2 minutes, the serving cells where the terminal is currently camped are cell a1, cell a2, cell a4, cell a5, and cell a6, then it can be queried that there are 5 serving cells in Table 2 that match the serving cells where the terminal is currently camped. target community, at this time, you can It is determined that the service cell where the terminal currently resides matches the cell fence information of the high-speed rail line.

In some embodiments, before querying the cell fence information of the high-speed rail line to see whether there is a second target cell matching the serving cell where the terminal currently resides, the method further includes: based on the electronic map and the geographical area where the terminal is currently located. The information determines the high-speed rail line where the terminal is currently located, and then the cell fence information of the high-speed rail line where the terminal is currently located can be queried to see if there is a second target cell that matches the serving cell where the terminal currently resides, and the current location of the terminal can be determined based on the query results. Whether the resident service cell matches the cell fence information of the high-speed rail line. Therefore, the matching speed can be improved and the power consumption of the terminal can be reduced.

In some embodiments, before querying whether there is a preset number of third target cells matching the serving cell where the terminal currently resides in the cell fence information of the high-speed rail line within a preset time, the method further includes: Determine the high-speed rail line where the terminal is currently located based on the electronic map and the current geographical area information of the terminal. Then, you can subsequently query whether there is a service cell where the terminal currently resides in the cell fence information of the high-speed rail line where the terminal is currently located within the preset time. Match a preset number of third target cells, and determine whether the service cell where the terminal currently resides matches the cell fence information of the high-speed rail line based on the query results. Therefore, the matching speed can be improved and the power consumption of the terminal can be reduced.

S408: Control the terminal to enter the high-speed rail line scene.

In some embodiments, the terminal leaves the high-speed rail station and enters the riding state, and the service cell where the terminal currently resides matches the cell fence information of the high-speed rail line, indicating that the carrier of the terminal is a person taking the high-speed rail. Then, the terminal can be controlled to enter the high-speed rail line scene.

In some embodiments, some applications (such as audio and video applications, news applications, etc.) will register high-speed rail line scene recognition through the application framework layer when they are installed or run, so that these applications can be identified through the application framework layer. The program is determined to be the target application that registers the terminal entry into the high-speed rail line scenario event. Then, when controlling the terminal to enter the high-speed rail scene, the instruction information for the terminal to enter the high-speed rail scene will be sent to the target application through the application framework layer, and the target application can perform the second cache operation according to the instruction information, so that when the user enters the high-speed rail scene Target applications in Terminal can also be used normally while on the line. In some embodiments, performing the second caching operation may include caching using a second caching amount, caching and playing using a second code rate, etc. The second cache amount is greater than the first cache amount, and the second code rate is less than the first code rate. It can be understood that performing the second caching operation may also include caching and playing using a second resolution, which is smaller than the first resolution, and this application does not limit this. It can be understood that for different applications, the second cache operation performed according to the instruction information may also be different. For example, the second cache operation performed for audio and video applications may be to increase the cache amount to the second cache amount and reduce the code rate to The second code rate, etc., the second caching operation performed by the news application may be to increase the preload amount to the second preload amount, etc. This application does not limit this.

As shown in Figure 5, when the application 501 (such as audio and video applications, news applications, etc.) is running in the application foreground, or when switching from the application background running to the application foreground, it registers the high-speed rail station with the terminal scene recognition device 502. During scene recognition, high-speed rail line scene recognition will also be registered with the terminal scene recognition device 502. Therefore, the terminal scene recognition device 502 can determine the application program 501 as the target application registered with the terminal entering the high-speed rail line scene event. When controlling the terminal to enter the high-speed rail line scene, the terminal scene identification device 502 will send the instruction information of the high-speed rail line scene caching strategy to the application program 501. The application program 501 will perform a second caching operation according to the instruction information of the high-speed rail scene caching policy. It is understandable that the application 501 may also register the high-speed rail line scene recognition with the terminal scene recognition device 502 when it is installed, runs in the application background, or switches from the application foreground to the application background; or the registration of the high-speed rail station scene recognition and the high-speed rail The registration of line scene recognition can also be performed at different times, and this application does not limit this. It can be understood that the application program 501 can also cancel the registration of high-speed rail line scene recognition with the terminal scene recognition device 502, and this application does not limit this.

In some embodiments, when the application performs the second cache operation according to the notification of controlling the terminal to enter the high-speed rail line scene, a second cache operation prompt can also be performed (as shown in Figure 8), thereby enabling the user to be aware of the high-speed rail line. Scene optimization is more perceptive. In Figure 8, the video application is performing the second caching operation. At this time, while the terminal is playing the video, a second prompt box pops up on the video interface. The second prompt box is used to prompt the user that the video application has enabled high-speed rail line scene optimization. In FIG. 8 , the second prompt box may be prompt 2, and the prompt 2 may be, for example, “High-speed rail line scene optimization has been started for you.” It can be understood that FIG. 8 is an example of the second prompt box, and this application does not limit the content and form of the second prompt box. It can be understood that the second prompt box may be displayed all the time when the second cache operation is performed, or may only be displayed for a few seconds. This application does not limit the display time of the second prompt box.

S409: Control the terminal to exit the high-speed rail station scene.

In some embodiments, the terminal leaves the high-speed rail station but the movement state of the terminal does not enter the riding state, or the service cell where the terminal currently resides does not match the cell fence information of the high-speed rail line, representing the carrier of the terminal. Not for people taking high-speed rail. Then, the terminal can be controlled to exit the high-speed rail station scene, so that the application program no longer needs to perform the first caching operation.

It can be understood that the community fence information of the high-speed rail lines can be the community fence information of the high-speed rail lines across the country, and this application does not limit this.

It can be understood that step S406 can be to determine that the terminal has left the high-speed rail station, and then perform step S407. Therefore, when the terminal does not support sensors to identify the riding status, the high-speed rail line scenario can be realized without resorting to the determination of the riding status. identification, this application does not limit this.

It can be understood that after step S408, the method also performs a process of exiting the high-speed rail line scenario. Please refer to Figure 9 , which is a flow chart of the process of exiting a high-speed rail line scenario provided by an embodiment of the present application. The process of exiting the high-speed rail line scenario includes:

S902: Determine whether the movement state of the terminal exits the riding state. If the movement state of the terminal exits the riding state, step S903 is executed. If the movement state of the terminal does not exit the riding state, step S902 is executed.

In some embodiments, after running on the high-speed rail line for a period of time, the user may arrive at the next high-speed rail station or even get off the high-speed rail. At this time, the terminal's motion state will exit the ride state. In some embodiments, if the acceleration data sensed by the acceleration sensor in the terminal is outside the high-speed rail operating acceleration range, the motion state of the terminal can be determined to exit the riding state; if the acceleration data sensed by the acceleration sensor in the terminal is outside the high-speed rail operating acceleration range, When it is within the range, it can be determined that the terminal's motion state has not exited the ride state. In some embodiments, if the speed data sensed by the speed sensor in the terminal is outside the high-speed rail operating speed range, the motion state of the terminal can be determined to exit the riding state; if the speed data sensed by the speed sensor in the terminal is within the high-speed rail operating speed range Within, it can be determined that the terminal's motion status has not exited the ride status. In some embodiments, whether the motion state of the terminal enters the riding state can be determined based on the acceleration data sensed by the acceleration sensor and the speed data sensed by the speed sensor in the terminal. This application does not limit this.

S903: Determine whether the serving cell where the terminal currently resides does not match any cell information in the cell fence information of the high-speed rail line. If the serving cell where the terminal currently resides does not match any cell information in the cell fence information of the high-speed rail line, step S904 is executed. If the serving cell where the terminal currently resides matches the cell information in the cell fence information of the high-speed rail line, step S902 is executed.

In some embodiments, it can be further determined whether the user has arrived at the next high-speed rail station, and may even get off the high-speed rail, by determining whether the serving cell where the terminal currently resides does not match any cell information in the cell fence information of the high-speed rail line. If the user has arrived at the next high-speed rail station, or may even get off the high-speed rail, the service cell where the terminal currently resides does not match any cell information in the cell fence information of the high-speed rail line. Determine whether the service cell where the terminal currently resides is the same as the cell of the high-speed rail line Any mismatch of cell information in the fence information may include: querying whether there is a second target cell matching the serving cell where the terminal currently resides in the cell fence information of the high-speed rail line; if there is no second target cell in the cell fence information of the high-speed rail line If there is a second target cell that matches the serving cell where the terminal is currently camped, it is determined that the serving cell where the terminal is currently camped does not match any cell information in the cell fence information of the high-speed rail line; if the cell fence information of the high-speed rail line If there is a second target cell that matches the serving cell where the terminal is currently camped, it is determined that the serving cell where the terminal is currently camped matches the cell information in the cell fence information of the high-speed rail line.

In some embodiments, when the high-speed rail is running on the high-speed rail line, it may be suspended for a period of time, but at this time the high-speed rail is still on the high-speed rail line. Determining whether the service cell where the terminal currently resides does not match any cell information in the cell fence information of the high-speed rail line may include: querying whether there is a service that the terminal currently resides in in the cell fence information of the high-speed rail line within a preset time The second target cell that the cell matches; if there is no second target cell that matches the serving cell where the terminal currently resides in the cell fence information of the high-speed rail line within the preset time, it is determined that the serving cell where the terminal currently resides is the same as the second target cell where the terminal currently resides. Any cell information in the cell fence information of the high-speed rail line does not match; if within the preset time, there is a second target cell in the cell fence information of the high-speed rail line that matches the serving cell where the terminal is currently camped, then it is determined that the terminal is currently camped. The remaining service cell matches the cell information in the cell fence information of the high-speed rail line. Then, the service cell where the terminal currently resides and the cell fence information of the high-speed rail line can be determined only when there is no second target cell matching the serving cell where the terminal currently resides for a preset time in the cell fence information of the high-speed rail line. Mismatch.

S904: The control terminal exits the high-speed rail line scene.

In some embodiments, after the terminal enters the high-speed rail line scene, the movement state of the terminal exits the ride state, and the service cell where the terminal currently resides does not match the cell fence information of the high-speed rail line, representing the carrier of the terminal Arrive at the next high-speed rail station and maybe even get off the high-speed rail. Then, the terminal can be controlled to exit the high-speed rail line scenario. At this time, as described in step S403, since the service cell where the terminal is currently camped and the cell fence information of the high-speed rail station will always be matched according to the preset cycle, or the service cell where the terminal is currently camped will be matched with the cell fence information where the terminal was camped last time. When the service cells are different, it is determined whether the service cell where the terminal currently resides matches the cell fence information of the high-speed rail station. After the control terminal exits the high-speed rail line scene, step S403 and subsequent steps will continue until the control terminal exits the high-speed rail station. Scenes. Or as described in step S401, since the current geographical area information of the terminal is obtained at a preset time interval, after the control terminal exits the high-speed rail line scene, step S401 and subsequent steps will continue until the control terminal exits the high-speed rail station scene.

It can be understood that, as mentioned above, in some embodiments, the terminal can download the community fence information of the high-speed rail station or the community fence information of the high-speed rail line from the cloud server in advance, so that the community fence information of the high-speed rail station and the community fence information of the high-speed rail line The fence information can be preset in the terminal, so that there is no need to download it from the cloud server when performing terminal scene recognition. In some embodiments, when performing terminal scene recognition, the terminal can download from the cloud server the cell fence information of the high-speed rail station or the cell fence information of the high-speed rail line that the terminal currently requires, such as downloading the cell of the high-speed rail station where the terminal is currently located geographically. Fence information, and community fence information of high-speed rail lines at the current high-speed rail station, etc., thus saving traffic during downloading. The community fence information of the high-speed rail station and the community fence information of the high-speed rail line can also be generated by the terminal and the cloud server. Please refer to Figure 10 , which is a flow chart of the process of generating high-speed rail station community fences and high-speed rail line community fences provided by the embodiment of the present application. The process of generating high-speed rail station community fences and high-speed rail line community fences can be applied to multiple terminals 1101 and cloud servers 1102 as shown in Figure 11. Only three terminals 1101 are shown in the figure, but it can be understood that the number of terminals 1101 can also be any other number, and this application does not limit this. The terminal 1101 may include a mobile phone with communication functions, a foldable electronic device, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook , cellular phone, personal digital assistant (personal digital assistant) digital assistant (PDA), or at least one of a wearable device. The terminal 1101 may include a position sensor, a mobile communication module, and a wireless communication module. The location sensor can detect the geographical location of the terminal 1101, such as longitude and latitude. In some embodiments, the location sensor may be GPS, Beidou or other positioning systems. The mobile communication module can be used to receive system messages broadcast by the base station 1103, and the wireless communication module can be used for the terminal 1101 to communicate with the cloud server 1102. The process of generating high-speed rail station community fences and high-speed rail line community fences includes:

S1001: Each terminal obtains the terminal's geographical location through a location sensor.

In some embodiments, the terminal obtains the terminal's geographical location through the location sensor only when the location sensor is turned on. The turning on may be only turning on when positioning is required, or turning on at preset time intervals. The number of terminal geographical locations obtained by each terminal may be one or more. For example, the terminal's geographical location may be the terminal's geographical location obtained by the location sensor at 9 a.m. and 9:30 a.m. respectively. The terminal geographical location may include a geographical location within a high-speed rail station, a geographical location on a high-speed rail line, or a geographical location that is not within a high-speed rail station but not on a high-speed rail line, etc.

Figure 12 shows five terminals (terminal 1, terminal 2, terminal 3, terminal 4 and terminal 5) acquiring the terminal geographical location. The five terminal geographical locations are location 1, location 2, location 3, location 4 and location 5 respectively. Among them, positions 1 and 2 are the geographical locations within high-speed rail station E, and locations 3, 4, and 5 are the geographical locations on the high-speed rail line (high-speed rail station E to high-speed rail station D). It can be understood that the number of terminals can be other numbers, the number of geographical locations within the high-speed rail station E can be other numbers, and the number of geographical locations on the high-speed rail line (high-speed rail station E to high-speed rail station D) can be For other quantities, the terminal geographical location may also include the geographical location in other high-speed rail stations and the geographical location on other high-speed rail lines, which is not limited by this application.

S1002: Each terminal monitors the serving cell where the terminal currently resides.

In some embodiments, the terminal may receive system messages broadcast by the base station, and monitor the serving cell where the terminal is currently camped based on the received system messages.

Continuing to take the above-mentioned Figure 12 as an example, the serving cells where the five terminals can monitor the terminals currently camp are respectively cell d1, cell d2, cell f1, cell f2, and cell f3.

S1003: Each terminal associates the terminal's geographical location with the serving cell where the terminal currently resides.

In some embodiments, when the terminal is in the serving cell where the terminal currently resides, the terminal's geographical location is obtained, or when the terminal's geographical location is obtained, the serving cell where the terminal currently resides is monitored. Then, the serving cell where the terminal currently resides may be a cell covering the geographical location of the terminal, and there is a certain correlation between the serving cell where the terminal currently resides and the terminal's geographical location.
