Detailed Description

In describing embodiments of the present application, words such as "for example" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "for example" is intended to present related concepts in a concrete fashion.

Unless defined otherwise, 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 terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. It should be understood that in this application, unless otherwise indicated, "a plurality" means two or more than two.

The prior art provides a user terminal mode control method, which can identify a terminal scene by utilizing a high-speed railway private network cell deployed by an operator. In the existing user terminal mode control method, when the motion state of a terminal is determined to be a riding state, a high-speed identifier (HighSpeedFlag is true) provided by a Modem (Modem) is obtained, wherein the high-speed identifier is an LTE (Long Term Evolution ) communication network system carrying data. If the high-speed identification can be continuously acquired within a set time (such as within 30 seconds), judging that the current state of the terminal is a high-speed rail riding state. The existing user terminal mode control method depends on the high-speed railway private network cells deployed by operators, which results in the fact that the high-speed railway scenes under the non-high-speed railway private network cannot be identified. Meanwhile, only a large number of high-speed railway private networks for China mobile are deployed at present, and China telecom and China Unicom do not deploy a large number of high-speed railway private networks and also do not have HighSpeedFlag identification. These will result in a lower terminal scene recognition rate for the existing user terminal mode control method. In view of this, the embodiment of the application provides a terminal scene recognition method, which can not depend on a high-speed railway private network cell deployed by an operator, and improves the recognition rate of a terminal scene.

First, a scenario in which the present application is applied will be described by taking a scenario when a high-speed rail is running on a high-speed rail as shown in fig. 1 as an example.

As shown in fig. 1, a high-speed rail is operated on a high-speed rail line covered by a plurality of cells for providing services to terminals moving on the high-speed rail line. The plurality of cells may include cells covered by common base station signals, or may further include cells covered by private base station signals, i.e. may include high-speed rail public network cells, or may further include high-speed rail private network cells. Each cell is a range covered by one base station or a part of a base station (sector antenna). A plurality of the cells may include cells supporting fourth generation (fourth generation, 4G) access technology, such as cells of long term evolution (long term evolution, LTE) access technology; alternatively, cells supporting fifth generation (5G) access technologies, such as cells of New Radio (NR) access technologies; alternatively, cells supporting multiple radio technologies, such as LTE technology and NR technology, may also be included. It is also understood that a plurality of said cells may also be cells adapted for future oriented communication technologies. Wherein each cell corresponds to a unique cell identification (cell ID).

The high-speed rail line may be divided into a plurality of high-speed rail line areas, each of which may be covered by one or more cells. In fig. 1, the high-speed rail line segment may be divided into six high-speed rail line regions (high-speed rail line region 1-high-speed rail line region 6). Each of the six high-speed rail regions may be covered by one or more cells. For example, the high-speed rail line area 3 may be covered by the cells 3 and 4. A terminal may camp under a certain cell of one or more cells covering a certain high-speed rail line area when passing through the high-speed rail line area. For example, in fig. 1, a terminal may camp under a cell 3 covering a high-speed rail line area 3 while passing through the high-speed rail line area 3. Thus, the terminal can access the network. It can be understood that when a terminal passes through a certain high-speed railway area, due to the high speed of the high-speed railway, the terminal can also be switched to a cell covering the next high-speed railway area without switching to a cell covering the high-speed railway area, i.e. directly skipping over the cell covering the high-speed railway area.

The workflow of the terminal software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking touch operation as touch click operation, taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video through the camera.

And when the method is executed, the cell fence information of the serving cell and the high-speed rail station where the terminal currently resides is always matched according to a preset period. Thus, when the terminal moves to any high-speed rail station, it can be determined that the serving cell in which the terminal currently resides matches the cell fence information of the high-speed rail station.

If the service cell in which the terminal is currently resident is different from the service cell in which the terminal is previously resident, whether the service cell in which the terminal is currently resident is matched with the cell fence information of the high-speed rail station or not can be judged. It can be understood that if the service cell in which the terminal currently resides is the same as the service cell in which the terminal previously resides, it is no longer necessary to determine whether the service cell in which the terminal currently resides matches with the cell fence information of the high-speed rail station, so that a process of identifying a scene of the terminal can be saved, and when the terminal moves to any high-speed rail station, it can be determined that the service cell in which the terminal currently resides matches with the cell fence information of the high-speed rail station.

In some embodiments, determining whether the serving cell in which the terminal is currently camping matches cell fence information of the high-speed rail station may include: inquiring whether a first target cell matched with a service cell where a terminal currently resides exists in cell fence information of the high-speed rail station; if a first target cell matched with the service cell where the terminal currently resides exists in the cell fence information of the high-speed rail station, judging that the service cell where the terminal currently resides is matched with the cell fence information of the high-speed rail station; if the first target cell matched with the service cell of the terminal currently resides in the cell fence information of the high-speed rail station does not exist, judging that the service cell of the terminal currently resides is not matched with the cell fence information of the high-speed rail station.

For example, if the serving cell in which the terminal is currently camping is cell 11, it may be queried that there is a first target cell (cell 11) in table 1 that matches the serving cell (cell 11) in which the terminal is currently camping, at which time it may be determined that the serving cell in which the terminal is currently camping matches the cell fence information of the high-speed rail station.

And when the terminal is controlled to enter the high-speed rail station scene, the indication information of the terminal entering the high-speed rail station scene is sent to the target application through the application program framework layer, and the target application can execute the first caching operation according to the indication information, so that the target application program of the terminal can be normally used when a user enters the high-speed rail station, and the target application program of the terminal can be normally used on the high-speed rail when the signal of the user on the high-speed rail is poor. In some embodiments, the performing the first buffering operation may be performing buffering with a first amount of buffering, performing buffering and playing with a first code rate, and so on. The first buffer capacity is larger than the buffer capacity of the application program buffer in the common state, and the first code rate is smaller than the code rate of the application program buffer and playing in the common state. It may be appreciated that the performing the first buffering operation may also be performing buffering and playing with a first resolution, where the first resolution is smaller than a resolution of the application program buffering and playing in the normal state, which is not limited in this application. It is understood that, for different applications, the first buffering operation performed according to the indication information may also be different, for example, for an audio/video application, the first buffering operation performed may be to increase the buffering amount to the first buffering amount, decrease the code rate to the first code rate, etc., and for a news application, the first buffering operation performed may be to increase the pre-load amount to the first pre-load amount, etc., which is not limited in this application.

As shown in fig. 5, when an application (e.g., an audio/video application, a news application, etc.) 501 is running in the application foreground or when the application is switched from the application background running to the application foreground, a high-speed rail scene recognition is registered in the terminal scene recognition device 502. Thus, the terminal scene recognition device 502 may determine the application 501 as a target application registered with a terminal entry high-speed rail scene event. In fig. 5, when the terminal is controlled to enter a high-speed rail station scene, the terminal scene recognition device 502 sends indication information of a high-speed rail station Jing Huancun policy to the application 501, and the application 501 performs a first buffering operation according to the indication information of the high-speed rail station Jing Huancun policy. It is to be understood that, the application 501 may register the scene recognition with the terminal scene recognition device 502 when it is installed, running in the background of the application, or when it is switched from the foreground of the application to the background of the application, which is not limited in this application. It is understood that the application 501 may also unregister the terminal scene recognition device 502 with the high-speed rail scene recognition, which is not limited in this application.

In some embodiments, when the application program executes the first cache operation according to the notification of controlling the terminal to enter the high-speed rail station scene, a first cache operation prompt (as shown in fig. 6) may also be executed, so that the user may have a stronger awareness of optimizing the high-speed rail station scene. In fig. 6, the video application is executing a first buffering operation, and at this time, the terminal pops up a first prompt box on the video interface while playing the video. The first prompt box is used for prompting a user that the video application program has started the optimization of the high-speed rail station scene. In fig. 6, the first prompt box may be prompt 1, which prompt 1 may be, for example, "have started a high-speed rail yard scenario optimization for you". It will be appreciated that fig. 6 is an example of the first prompt box, and the content and form of the first prompt box are not limited in this application. It can be understood that the first prompt box may be displayed all the time when the first cache operation is executed, or may be displayed for only a few seconds, and the time of displaying the first prompt box is not limited in this application.

S405: and obtaining the district fence information of the high-speed railway line.

In some embodiments, the cell fence information of the high-speed rail line is cell fence information of the high-speed rail line. The cell fence information for the high-speed rail line may be a virtual boundary bounded by all cells covering the geographic area of the high-speed rail line. The cell fence information of the high-speed rail line includes an identification (cell ID) of all cells covering a geographical area of the high-speed rail line. It will be appreciated that the cell fence information of the high-speed rail may also be a virtual boundary defined by a majority of cells covering the geographic area of the high-speed rail, which is not limited in this application.

In some embodiments, the cell fence information of the high-speed rail may also be cell fence information of the high-speed rail of the geographical area information in which the terminal is currently located, for example, cell fence information of the high-speed rail of XX city.

In some embodiments, the cell fence information of the high-speed rail may also be cell fence information of the high-speed rail station where the terminal is currently located. Specifically, after step S403 and before step S404, the method further includes: and determining the high-speed rail station where the terminal is currently located. The acquiring the cell fence information of the high-speed rail line may include acquiring the cell fence information of the high-speed rail line of the high-speed rail station where the determined terminal is currently located. In some embodiments, the cell fence information of the high-speed rail may further include path information of the high-speed rail station where the terminal is currently located. For example, as shown in fig. 7, if the terminal is currently located at the high-speed rail station a, three routes are included from the high-speed rail station a as a start point, namely, a high-speed rail line L1 from the high-speed rail station a to the high-speed rail station B, a high-speed rail line L2 from the high-speed rail station a to the high-speed rail station C, and a high-speed rail line L3 from the high-speed rail station a to the 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 path information of the high-speed rail line L1, the high-speed rail line L2 and the high-speed rail line L3, and the cell fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located includes cell fence information of the high-speed rail line L1, cell fence information of the high-speed rail line L2 and cell fence information of the high-speed rail line L3. If the terminal is currently located in the high-speed rail station D, the high-speed rail station D is taken as a starting point, and 4 routes are respectively a high-speed rail line L3 from the high-speed rail station D to the high-speed rail station a, a high-speed rail line L4 from the high-speed rail station D to the high-speed rail station E, a high-speed rail line L5 from the high-speed rail station D to the high-speed rail station F, and a high-speed rail line L6 from the high-speed rail station D to the 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 path information of the high-speed rail line L3, the high-speed rail line L4, the high-speed rail line L5 and the high-speed rail line L6, and the cell fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located includes cell fence information of the high-speed rail line L3, cell fence information of the high-speed rail line L4, cell fence information of the high-speed rail line L5 and cell fence information of the high-speed rail line L6.

Wherein each high-speed rail line may be divided into a plurality of high-speed rail line areas, each high-speed rail line area may be covered by one or more cells, for example, high-speed rail line L1 may be divided into six high-speed rail line areas, each of which may be covered by one or more cells, and thus a terminal may not be switched to a cell covering a high-speed rail line area of the location due to a high-speed rail speed, etc., while the terminal is operating on the high-speed rail line, and a serving cell where the terminal resides may be different when the terminal passes through different times at the same location on the high-speed rail line.

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

The cell fence information of the high-speed railway line can be as follows in table 2:

TABLE 2

It will be appreciated that table 2 is an example of the cell fence information of the high-speed rail line of the high-speed rail station where the terminal is currently located, and the cell fence information of the high-speed rail line may also omit the high-speed rail station fence, or may also omit the high-speed rail line fence, and the content and form of the cell fence information of the high-speed rail line are not limited in this application.

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

In some embodiments, the cell fence information for the high-speed rail may be obtained from a cloud server.

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

In some embodiments, since some people may not leave the high-speed rail station (e.g., a worker of the high-speed rail station, etc.) although entering the high-speed rail station, or leave the high-speed rail station but not ride, it is necessary to distinguish whether the terminal leaves the high-speed rail station and the movement state enters the ride state.

In some embodiments, whether the terminal leaves the high-speed rail station is determined by determining whether the serving cell in which the terminal is currently camping continues to match the cell fence information of the high-speed rail station. If the service cell where the terminal is currently resident continues to be matched with the cell fence information of the high-speed rail station, the terminal can be determined not to leave the high-speed rail station. If the service cell where the terminal is currently resident does not continue to match the cell fence information of the high-speed rail station, the terminal can be determined to leave the high-speed rail station.

In some embodiments, whether the motion state of the terminal enters the riding state may be determined by acceleration data sensed by the acceleration sensor of the terminal. When the high-speed rail runs on the high-speed rail, the acceleration is stable, and if the terminal is positioned on the high-speed rail, the acceleration sensed by the terminal is also stable and is positioned in the movement acceleration range of the high-speed rail. If the acceleration data sensed by the acceleration sensor in the terminal is positioned in the running acceleration range of the high-speed rail, the movement state of the terminal can be determined to enter a riding state; if the acceleration data sensed by the acceleration sensor in the terminal is located outside the high-speed rail running acceleration range, the movement state of the terminal can be determined not to enter the riding state.

In some embodiments, whether the motion state of the terminal enters the riding state may be determined by speed data sensed by a speed sensor in the terminal. The speed of the high-speed rail after acceleration is completed on the high-speed rail is within the running speed range of the high-speed rail. If the speed data sensed by the speed sensor in the terminal is in the high-speed rail running speed range, determining that the motion state of the terminal enters a riding state; if the speed data sensed by the speed sensor in the terminal is located outside the high-speed rail running speed range, it can be determined that the movement state of the terminal does not enter the riding state.

In some embodiments, whether the motion state of the terminal enters the riding state may be determined by acceleration data sensed by the acceleration sensor and speed data sensed by the speed sensor in the terminal, which is not limited in this application.

S407: and judging whether the service cell where the terminal currently resides is matched with the cell fence information of the high-speed railway line. If the serving cell in which the terminal is currently located matches the cell fence information of the high-speed railway, step S408 is performed. If the serving cell in which the terminal is currently located is not matched with the cell fence information of the high-speed railway, step S409 is executed.

In some embodiments, since the running state of the common vehicle (car, etc.) is similar to that of the high-speed rail, after the terminal starts from the high-speed rail station and the running state enters the riding state, it is further required to distinguish whether the terminal is currently located on the high-speed rail or on the common vehicle, and it is required to determine whether the serving cell in which the terminal is currently located matches with the cell fence information of the high-speed rail.

In some embodiments, determining whether the serving cell in which the terminal is currently camping matches cell fence information of the high-speed rail may include: inquiring whether a second target cell matched with a service cell where the terminal currently resides exists in the cell fence information of the high-speed rail; if a second target cell matched with the service cell where the terminal currently resides exists in the cell fence information of the high-speed railway, judging that the service cell where the terminal currently resides is matched with the cell fence information of the high-speed railway; if the second target cell matched with the service cell of the terminal currently resides in the cell fence information of the high-speed railway is not existed, judging that the service cell of the terminal currently resides is not matched with the cell fence information of the high-speed railway.

For example, if the serving cell in which the terminal is currently camping is cell b7, it may be queried that there is no second target cell in table 1 that matches the serving cell in which the terminal is currently camping (cell b 7), and at this time, it may be determined that the serving cell in which the terminal is currently camping does not match the cell fence information of the high-speed rail.

In some embodiments, the high-speed rail is more stable and faster in acceleration and can travel longer distances in a shorter time when operating on the high-speed rail. The terminal on the high-speed rail is also rapidly moved to a different high-speed rail region in a short time. Since each high-speed rail line area can be covered by one or more cells, the terminal can rapidly switch to a different cell in a shorter time, and the serving cell in which the terminal currently resides also rapidly changes. Sometimes, due to the high-speed and the like, when the high-speed rail passes through a certain high-speed rail area, the terminal on the high-speed rail is not even switched to a cell covering the certain high-speed rail area, and then the high-speed rail is quickly moved to the next high-speed rail area, and then the terminal does not reside in the cell covering the certain high-speed rail area on the high-speed rail. Then, the determining whether the serving cell in which the terminal currently resides matches the cell fence information of the high-speed rail may include: inquiring whether a preset number of third target cells matched with a service cell where a terminal currently resides exist in cell fence information of the high-speed railway within preset time; if a preset number of third target cells matched with the service cell where the terminal currently resides exist in the cell fence information of the high-speed railway in the preset time, judging that the service cell where the terminal currently resides is matched with the cell fence information of the high-speed railway; if the preset number of third target cells matched with the service cell where the terminal currently resides does not exist in the cell fence information of the high-speed railway line within the preset time, judging that the service cell where the terminal currently resides is not matched with the cell fence information of the high-speed railway line.

For example, if the serving cell in which the terminal is currently located is cell a1, cell a2, cell a4, cell a5, or cell a6 within 2 minutes, it may be queried that there are 5 target cells in table 2 that match the serving cell in which the terminal is currently located, and at this time, it may be determined that the serving cell in which the terminal is currently located matches the cell fence information of the high-speed rail.

In some embodiments, before querying whether there is a second target cell in the cell fence information of the high-speed rail that matches a serving cell in which the terminal is currently camping, the method further comprises: and determining a high-speed rail line where the terminal is currently located according to the electronic map and the geographical area information where the terminal is currently located, then inquiring whether a second target cell matched with a service cell where the terminal is currently located exists in the cell fence information of the high-speed rail line where the terminal is currently located, and determining whether the service cell where the terminal is currently located is matched with the cell fence information of the high-speed rail line according to an inquiring result. 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 in the cell fence information of the high-speed rail that match the serving cell in which the terminal currently resides within a preset time, the method further includes: and determining a high-speed rail line where the terminal is currently located according to the electronic map and the geographical area information where the terminal is currently located, then inquiring whether a preset number of third target cells matched with the service cell where the terminal is currently located exist in the cell fence information of the high-speed rail line where the terminal is currently located within a preset time, and determining whether the service cell where the terminal is currently located is matched with the cell fence information of the high-speed rail line according to an inquiring result. Therefore, the matching speed can be improved, and the power consumption of the terminal can be reduced.

S408: and controlling the terminal to enter a high-speed railway line scene.

In some embodiments, the terminal leaves the high-speed rail station and the movement state enters the riding state, and the serving cell in which the terminal currently resides matches the cell fence information of the high-speed rail line, representing that the carrier of the terminal is a person riding the high-speed rail. The terminal may be controlled to enter a high-speed rail scenario.

In some embodiments, some applications (e.g., audio-video type applications, news type applications, etc.) may register high-speed rail scene recognition at installation or runtime through the application framework layer, such that these applications may be determined by the application framework layer to be the target applications registered with the terminal entry high-speed rail scene event. And when the terminal is controlled to enter the high-speed railway line scene, the indication information of the terminal entering the high-speed railway line scene is sent to the target application through the application program framework layer, and the target application can execute the second cache operation according to the indication information, so that the target application program of the terminal can be normally used when a user enters the high-speed railway line. In some embodiments, the performing the second buffering operation may be performing buffering with a second amount of buffering, performing buffering and playing with a second code rate, and so on. The second buffer amount is larger than the first buffer amount, and the second code rate is smaller than the first code rate. It is understood that performing the second buffering operation may also be performing buffering and playing, etc. with a second resolution, which is less than the first resolution, as this application is not limited in this regard. It is understood that, for different applications, the second buffering operation performed according to the indication information may also be different, for example, the second buffering operation performed for the audio/video application may be to increase the buffering amount to the second buffering amount and decrease the code rate to the second code rate, etc., and the second buffering operation performed for the news application may be to increase the pre-load amount to the second pre-load amount, etc., which is not limited in this application.

As shown in fig. 5, when an application 501 (for example, an audio/video application, a news application, or the like) is running in the foreground of an application or when switching from the background of the application to the foreground of the application, a high-speed rail scene recognition is registered in the terminal scene recognition device 502, and a high-speed rail scene recognition is also registered in the terminal scene recognition device 502. Thus, the terminal scenario recognition device 502 may determine the application 501 as the target application registered with the terminal entry into the high-speed rail scenario event. When the terminal is controlled to enter the high-speed railway scene, the terminal scene recognition device 502 sends indication information of the cache policy of the high-speed railway scene to the application 501. The application 501 may execute a second cache operation according to the indication information of the cache policy of the high-speed railway scene. It can be appreciated that the application 501 may register the high-speed rail line scene recognition with the terminal scene recognition device 502 when it is installed, running in the application background, or when it is switched from the application foreground running to the application background; or the registration of the high-speed rail station scene recognition and the registration of the high-speed rail line scene recognition may be different, which is not limited in the present application. It is understood that the application 501 may also unregister the high-speed railway scene recognition with the terminal scene recognition device 502, which is not limited in this application.

In some embodiments, when the application program executes the second cache operation according to the notification of controlling the terminal to enter the high-speed railway scene, a second cache operation prompt (as shown in fig. 8) may also be executed, so that the user may have a stronger awareness of optimizing the high-speed railway scene. In fig. 8, the video application is executing a second buffering operation, and at this time, the terminal pops up a second prompt box on the video interface while playing the video. The second prompt box is used for prompting the user that the video application program has started the high-speed railway scene optimization. In fig. 8, the second prompt box may be prompt 2, and the prompt 2 may be, for example, "have started a high-speed rail scene optimization for you". It will be appreciated that fig. 8 is an example of the second prompt box, and the content and form of the second prompt box are not limited in this application. It can be understood that the second prompt box may be displayed all the time when the second cache operation is executed, or may be displayed for only a few seconds, and the time for displaying the second prompt box is not limited in this application.

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

In some embodiments, the terminal leaves the high-speed rail station but the motion state of the terminal does not enter a riding state, or the serving cell in which the terminal currently resides does not match the cell fence information of the high-speed rail line, representing that the carrier of the terminal is not a person riding the high-speed rail. And controlling the terminal to exit the high-speed rail station scene, so that the application program does not need to execute the first caching operation.

It is understood that the cell fence information of the high-speed rail line may be cell fence information of a national high-speed rail line, which is not limited in this application.

It will be appreciated that step S406 may be to determine that the terminal leaves the high-speed rail station, and then execute step S407, so that the recognition of the high-speed rail scene may be implemented when the terminal does not support the recognition of the riding state by the sensor, that is, without resorting to the determination of the riding state, which is not limited in this application.

It is understood that after step S408, the method also performs an exit high-speed rail scenario procedure. Referring to fig. 9, a flowchart of a process of exiting a high-speed rail scenario is provided in an embodiment of the present application. The process of exiting the high-speed railway scene comprises the following steps:

s902: and judging whether the motion state of the terminal exits from the riding state. If the motion state of the terminal exits the riding state, step S903 is performed. If the motion state of the terminal does not exit the riding state, step S902 is executed.

In some embodiments, the user may reach the next high-speed rail station or may even drop the high-speed rail after traveling on the high-speed rail for a period of time with the high-speed rail. At this time, the movement state of the terminal will exit the riding state. In some embodiments, if the acceleration data sensed by the acceleration sensor in the terminal is outside the high-speed rail running acceleration range, determining that the motion state of the terminal exits the riding state; if the acceleration data sensed by the acceleration sensor in the terminal is in the high-speed rail running acceleration range, the movement state of the terminal can be determined not to exit from the riding 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, it may be determined that the movement state of the terminal exits the riding state; if the speed data sensed by the speed sensor in the terminal is within the high-speed rail running speed range, it can be determined that the movement state of the terminal does not exit the riding state. In some embodiments, whether the motion state of the terminal enters the riding state may be determined by acceleration data sensed by the acceleration sensor and speed data sensed by the speed sensor in the terminal, which is not limited in this application.

S903: and judging whether the service cell where the terminal currently resides is not matched with any cell information in the cell fence information of the high-speed railway line. If the serving cell in which the terminal is currently located does not match any cell information in the cell fence information of the high-speed railway, step S904 is performed. If the serving cell in which the terminal is currently located matches the cell information in the cell fence information of the high-speed railway, step S902 is executed.

In some embodiments, it may be further determined whether the user arrives at the next high-speed rail station, and possibly even the next high-speed rail, by determining whether the serving cell in which the terminal is currently camping does not match any of the cell fence information for the high-speed rail. If the user has arrived at the next high-speed rail station, and possibly even down the high-speed rail station, the service cell where the terminal is currently resident is not matched with any cell information in the cell fence information of the high-speed rail. The determining whether the service cell in which the terminal currently resides is not matched with any cell information in the cell fence information of the high-speed railway line may include: inquiring whether a second target cell matched with a service cell where the terminal currently resides exists in the cell fence information of the high-speed rail; if the second target cell matched with the service cell of the terminal currently resides in the cell fence information of the high-speed railway is not present, judging that the service cell of the terminal currently resides is not matched with any cell information in the cell fence information of the high-speed railway; and if the second target cell matched with the service cell currently resided in the terminal exists in the cell fence information of the high-speed railway, judging that the service cell currently resided in the terminal is matched with the cell information in the cell fence information of the high-speed railway.

In some embodiments, the high-speed rail may be suspended for a period of time while operating on the high-speed rail, but the high-speed rail is still on the high-speed rail at this time. The determining whether the service cell in which the terminal currently resides is not matched with any cell information in the cell fence information of the high-speed railway line may include: inquiring whether a second target cell matched with a service cell where the terminal currently resides exists in the cell fence information of the high-speed rail within preset time; if the second target cell matched with the service cell where the terminal currently resides does not exist in the cell fence information of the high-speed railway within the preset time, judging that the service cell where the terminal currently resides is not matched with any cell information in the cell fence information of the high-speed railway; if a second target cell matched with the service cell where the terminal currently resides exists in the cell fence information of the high-speed railway within the preset time, judging that the service cell where the terminal currently resides is matched with the cell information in the cell fence information of the high-speed railway. And judging that the cell fence information of the service cell where the terminal currently resides is not matched with the cell fence information of the high-speed railway only when the second target cell which is matched with the service cell where the terminal currently resides does not exist in the cell fence information of the high-speed railway for a preset time.

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

In some embodiments, after the terminal enters the high-speed rail scene, the motion state of the terminal exits the riding state, and the serving cell in which the terminal currently resides is not matched with the cell fence information of the high-speed rail, representing that the carrier of the terminal arrives at the next high-speed rail station, and even the high-speed rail is likely to be down. And then the terminal can be controlled to exit the high-speed railway scene. At this time, as described in step S403, since the cell fence information of the serving cell where the terminal currently resides and the high-speed rail station is always matched according to the preset period, or when the serving cell where the terminal currently resides is different from the serving cell where the terminal previously resides, it is determined whether the serving cell where the terminal currently resides is matched with the cell fence information of the high-speed rail station, after the control terminal exits the high-speed rail circuit scene, step S403 and subsequent steps are continuously performed until the control terminal exits the high-speed rail station scene. Or as described in step S401, since the information of the geographical area where the terminal is currently located is obtained according to the preset time interval, after the control terminal exits the high-speed rail scene, the step S401 and the subsequent steps will be continuously executed until the control terminal exits the high-speed rail station scene.

It may be appreciated that, as described above, in some embodiments, the terminal may download the cell fence information of the high-speed rail station or the cell fence information of the high-speed rail line from the cloud server in advance, so that the cell fence information of the high-speed rail station and the cell fence information of the high-speed rail line may be preset in the terminal, so that the terminal need not be downloaded from the cloud server when performing the terminal scene recognition. In some embodiments, the terminal may download, from the cloud server, cell fence information of a high-speed rail station or cell fence information of a high-speed rail line currently required by the terminal when performing terminal scene recognition, and download cell fence information of a high-speed rail station, cell fence information of a high-speed rail line of the high-speed rail station currently located with the terminal, and the like, thereby saving traffic when 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 a terminal and a cloud server. Referring to fig. 10, a flowchart of a process for generating a high-speed rail station cell fence and a high-speed rail line cell fence according to an embodiment of the present application is provided. The process of generating the high-speed rail station cell fences and the high-speed rail line cell fences may be applied to a plurality of terminals 1101 and cloud servers 1102 as shown in FIG. 11. Only three terminals 1101 are shown, but it is to be understood that the number of terminals 1101 is any other number and is not limited in this application. The terminal 1101 may include at least one of a cellular telephone, 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, a cellular telephone, a personal digital assistant (personal digital assistant, PDA), or a wearable device having communication capabilities. The terminal 1101 may include a position sensor, a mobile communication module, and a wireless communication module. The position sensor may detect a geographic location of the terminal 1101, such as a latitude and longitude, or the like. In some embodiments, the position sensor may be a GPS, beidou, or other positioning system. The mobile communication module may be configured to receive a system message broadcast by the base station 1103 and the wireless communication module may be configured to allow the terminal 1101 to communicate with the cloud server 1102. The process of generating the high-speed rail station community fence and the high-speed rail line community fence comprises the following steps:

S1001: each terminal obtains the geographic position of the terminal through a position sensor.

In some embodiments, the terminal obtains the terminal geographic location through the location sensor only when the location sensor is on. The opening may be only when positioning is required, or at preset time intervals. The number of terminal geographical locations acquired per terminal may be one or more. For example, the terminal geographic location may be a terminal geographic location acquired by a location sensor at 9 am and 9:30 am, respectively. The terminal geographic location may include a geographic location within a high-speed rail station, a geographic location on a high-speed rail line, or a geographic location within a non-high-speed rail station and on a non-high-speed rail line, etc.

Five terminals (terminal 1, terminal 2, terminal 3, terminal 4 and terminal 5) are shown in fig. 12 to obtain the terminal geographical location. The five terminal geographic locations are location 1, location 2, location 3, location 4, and location 5, respectively. Where position 1 and position 2 are geographic locations within high-speed rail station E, and position 3, position 4, and position 5 are geographic locations on the high-speed rail lines (high-speed rail station E through high-speed rail station D).
