[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0025] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0026] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0027] In the field of communication technology, cell switching refers to the channel switching performed to ensure uninterrupted terminal communication when a terminal moves from one cell to another.

[0028] However, the network status in mobile scenarios is complex and unstable, and the network is often slow. In the related technology, for the above situation, one method is that the terminal device completely obeys the scheduling of the network-side base station and switches cells according to the base station signaling, that is, when the terminal device moves from one base station cell to another, the network-side base station will automatically determine when to switch cells based on the signaling and algorithm to ensure the continuity and stability of communication; the other method is to actively identify such poor network quality when the terminal device cannot access the Internet or the Internet access is slow, trigger the cell switching through specific commands, and try to connect to other base station cells with better network quality.

[0029] However, in the above scheme, it is impossible to make advance processing or explanation for the situation of poor network quality. The only thing to do is to passively wait for the baseline scheduling to change the cell (base station or the coverage area of ​​the base station) or wait for the network problem to occur before processing. This will cause the terminal device to experience more obvious network lag or even unavailability, reducing the user's network experience.

[0030] In view of this, an embodiment of the present application provides a cell switching method, which can perform cell switching for terminal devices in advance according to different recommended information, thereby increasing the probability of terminal devices staying in good cells, reducing the probability of terminal devices staying in poor cells, and improving user network experience.

[0037] Figure 2 A schematic diagram of the structure of a terminal device provided in an embodiment of the present application.

[0038] For example, Figure 2 As shown, the terminal device 20 may include a processor 201 , an external memory interface 202 , an internal memory 203 and a universal serial bus (USB) interface 204 .

[0039] It is understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the terminal device 20. In other embodiments of the present application, the terminal device 20 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0040] The processor 201 may include one or more processing units, for example: the processor 201 may include an application processor (application processor, AP), a modem processor, a graphics processor (graphics processing unit, GPU), an image signal processor (image signal processor, ISP), a controller, a video codec, a digital signal processor (digital signal processor, DSP), a baseband processor, and / or a neural network processor (neural network processing unit, NPU), etc. Among them, different processing units can be independent devices or integrated in one or more processors. Exemplarily, the processor 201 can be a smart terminal CPU, such as a Snapdragon series processor, etc. In some embodiments, the processor 201 may include one or more interfaces. The interface may include an inter integrated circuit (I2C) interface, an inter integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0041] The external memory interface 202 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the terminal device 20.

[0043] In addition, the terminal device involved in the embodiment of the present application may also be installed with an operating system, and application programs can be installed and run on the operating system, which is not limited by the embodiment of the present application.

[0044] Figure 3 The following is a schematic diagram of the implementation process of the cell switching method provided in the embodiment of the present application. Figure 3 As shown, the method may include the following steps 301 to 302:

[0045] Step 301, when the terminal device is in a target scenario where the cell switching frequency is greater than or equal to a preset frequency threshold, the associated cells of the current cell are obtained from a preset database according to the current cell of the terminal device. The associated cells include neighboring cells of the current cell and future cells. The future cell is a cell in which the terminal device can reside within a preset time after the current moment and the residence time satisfies the time threshold. The preset database contains the association relationship between each cell in all lines under the target scenario and the corresponding associated cell.

[0046] In the embodiment of the present application, there is no limitation on the specific scenario type of the target scenario, and the target scenario is a scenario in which the cell switching frequency of the terminal device is greater than or equal to a preset frequency threshold.

[0047] For example, the target scenario may be a high-speed rail driving scenario. In this scenario, the high-speed rail travels at a high speed, which can usually reach 350km / h or even higher. This causes the train to move from the coverage of one base station to the coverage of another base station in a very short time, resulting in a faster cell switching frequency of the terminal device in the high-speed rail line. Alternatively, the target scenario may also be a subway driving scenario. In this scenario, since the subway travels at a high speed, the cell switching frequency of the terminal device in the subway line is also fast. Alternatively, the target scenario may also be a driving scenario, such as a user driving a vehicle to a certain place. In this scenario, since the vehicle travels at a high speed, the cell switching frequency of the terminal device in the driving line is also fast.

[0048] In the embodiments of the present application, there is no limitation on the value of the preset frequency threshold. For example, the preset frequency threshold can be set for one type of scenario, such as setting the preset frequency threshold only according to the high-speed rail scenario; or, the preset frequency threshold can be set for a variety of scenarios in combination, such as setting the preset frequency threshold based on high-speed rail scenarios, subway scenarios, etc.

[0049] When the cell switching frequency of the terminal device is greater than or equal to the preset frequency threshold, it means that the terminal device is in a scenario where it needs to quickly switch cells. In this case, if the terminal device cannot switch the access cell in time, it may cause the terminal device to experience more obvious network lag or even unavailability, reducing the user's network experience.

[0050] Based on this, in an embodiment of the present application, in the above scenario, based on the current resident cell of the terminal device, an associated cell associated with the current resident cell can be obtained from a preset database, so as to determine the current information to be recommended in advance based on the current resident cell and the associated cell, so as to further perform cell switching of the terminal device in advance based on the current information to be recommended, thereby ensuring the communication quality of the terminal device.

[0051] In some embodiments, according to the current resident cell of the terminal device, the associated cell associated with the current resident cell is obtained from the preset database, and the associated cell associated with the current resident cell is searched from the preset database according to the cell identification information of the current resident cell of the terminal device.

[0052] In the embodiment of the present application, the preset database pre-stores the association relationship between each cell in all lines under the target scenario and the associated cell corresponding to the cell.

[0053] In an embodiment of the present application, the associated cells of a certain cell may include neighboring cells and future cells corresponding to the cell. Among them, neighboring cells are other cells adjacent to the cell, and the neighboring cells overlap with the cell in signal coverage. Future cells refer to cells where a terminal device can reside within a preset time after the current moment on the basis of its residency in the cell, and the residency time meets the time threshold. That is, a future cell is a cell that a terminal device enters its coverage after x seconds from the current moment, and the terminal device can reside in the cell for y seconds.

[0054] Among them, all routes in the target scenario may include the usual travel routes of the user holding the terminal device, or the travel routes in the city where the user holding the terminal device is currently located. For example, all routes in the target scenario may be the routes that the user usually travels on business, such as the high-speed rail route from City A to City B; or they may also be the user's commuting routes, such as the subway line from A to B.

[0055] Figure 4 A schematic diagram of the effect of the association relationship in a preset database is given. It can be understood that the preset database may include the association relationship between each cell in multiple lines and the corresponding associated cell. Here, for the convenience of description, one of the lines A in the preset database is taken as an example for explanation.

[0056] like Figure 4 As shown, for route A, the route A includes multiple passing cells, such as passing cell 1, passing cell 2, passing cell 3... passing cell N, etc. For each passing cell, the preset database also stores information of associated cells corresponding to each passing cell. Here, there is no limit on the number of associated cells corresponding to the passing cells, such as one passing cell can be associated with one neighboring cell and one future cell, or one passing cell can be associated with multiple neighboring cells and multiple future cells, etc.

[0057] For example, for the passing cell 1, its corresponding associated cells may be the neighboring cell 1 and the future cell 1; for the passing cell 2, its corresponding associated cells may be the neighboring cell 2, the neighboring cell 3 and the future cell 2 and the future cell 3; for the passing cell 3, its corresponding associated cells may be the neighboring cell 4 and the future cell 4, the future cell 5... For the passing cell N, its corresponding associated cells may be the neighboring cell M and the future cell K, etc.

[0058] In some embodiments, since the preset database contains the association relationship between each cell in all lines under the target scene and the corresponding associated cell, the specific line of the target scene where the terminal device is currently located can be determined first, and then the associated cell corresponding to the current resident cell can be obtained from the preset database based on the specific line of the target scene where the terminal device is currently located and the current resident cell of the terminal device.

[0059] In some embodiments, in order to determine the specific route of the target scene where the terminal device is currently located, the cell information of the resident cells that the terminal device has passed through within a period of time (such as 10 minutes to 20 minutes) can be first obtained, and the cell information may include the cell identification of each resident cell, such as the cell ID of the resident cell, etc.; then, according to the obtained cell information of multiple consecutive resident cells corresponding to the terminal device, the cell information of the passing cells in each route in the preset database is matched to obtain the matching result of the terminal device and each route; when the matching result of a certain route is greater than the matching threshold, it can be determined that the specific route of the target scene where the terminal device is currently located is this route.

[0060] In the embodiment of the present application, the storage location of the preset database is not limited. For example, the preset database can be stored in a cloud server. In this way, when the terminal device needs to use the stored data in the preset database, it can download the data in the preset database from the cloud server in advance. Here, when the terminal device downloads the data in the preset database, it can simultaneously download the data in the preset database for all commonly used routes of the terminal device, or it can only download the data in the current route of the terminal device, which is not limited.

[0061] Alternatively, the preset database may also be stored in the terminal device, so that after the terminal device determines the current driving route, the association relationship between each cell corresponding to the current driving route and the corresponding associated cell can be called from the stored preset database.

[0062] In the embodiments of the present application, there is no limitation on the timing and conditions for constructing the preset database. For example, in some embodiments, information of multiple passing cells included in a certain route and associated cells corresponding to each passing cell can be collected in advance, and the information can be associated and stored in the preset database for subsequent use.

[0063] In the embodiment of the present application, there is no limitation on the division method of the line types stored in the preset database. For example, the storage can be performed according to the identification of the terminal device, and multiple lines corresponding to the same terminal device can be stored in the same location. For example, the identification of the terminal device can include the International Mobile Equipment Identity (IMEI), the Mobile Equipment Identifier (MEID), the Globally Unique Identifier (UUID), etc.; or, the storage can also be performed according to the type of line, such as storing multiple subway lines in City A in the same location, and storing high-speed rail lines from City A to City B, City A to City C, etc. in the same location.

[0064] In the embodiments of the present application, there is no limitation on the type of cell information stored in the preset database. For example, in some embodiments, the preset database may only store the identification information of the cell and the identification information of the associated cells corresponding to the cell; in other embodiments, the preset database may also store the identification information of the cell and the information reflecting the signal quality of the cell, as well as the identification information of the associated cells corresponding to the cell and the information reflecting the signal quality of the cell.

[0065] In the embodiments of the present application, there is no limitation on the type of the preset database. For example, in some embodiments, the preset database may be a knowledge graph database, a relational database, a graph database, a document database, etc.

[0066] Among them, the knowledge graph database is a database specially used to store and process graph structure data. The entities, attributes and relationships in the knowledge graph are represented as nodes and edges of the graph. Nodes represent entities, and edges represent relationships between entities. Nodes and edges can also carry attribute information. After obtaining the information of each cell and associated cells in the line, this information can be processed to form a knowledge graph database.

[0067] In some embodiments, when processing the acquired cell information, model training can also be performed based on the collected cell information. After the training is completed, the training results are deployed on the terminal device, and then retrained based on the personalized data of the user holding the terminal device, no longer relying on the advance collection of data.

[0068] Of course, when obtaining the preset database, it is also necessary to ensure that the cell information in the preset database is updated in real time to reflect the latest network conditions in the line.

[0069] A relational database management system (RDBMS) is a database based on a relational model. It uses tables (i.e., relationships) to store data. Each table consists of rows and columns, where rows represent records and columns represent fields. A graph database is a database specifically designed to store and process graph-structured data. In a graph database, data is stored in the form of nodes (representing entities) and edges (representing relationships between entities). A document database is a non-relational database that stores data in the form of documents. Each document is a self-contained collection of key-value pairs that can contain multiple data types and nested structures.

[0070] Step 302, according to the cell types of the current resident cell and the associated cells, obtain the current information to be recommended, so that the terminal device performs cell switching according to the current information to be recommended, and the cell types include excellent cell types and poor cell types.

[0071] In the embodiment of the present application, the cell type of the cell may include an excellent cell type and a poor cell type.

[0072] When classifying cells into cell types, the cell types may be determined based on the cell signal quality. For example, a cell with a signal quality greater than a quality threshold may be determined as an excellent cell, and a cell with a signal quality lower than a quality threshold may be determined as a poor cell.

[0073] The signal quality of a cell can be measured by multiple indicators, including signal to interference plus noise ratio (SINR), reference signal received power (RSRP), carrier received signal strength (RSSI), and reference signal received quality (RSRQ).

[0074] In an embodiment of the present application, the cell type of the cell is predetermined and stored. When determining the cell type of the cell, illustratively, the user has carried the terminal device from home to the company at 8 a.m. in the past 5 days. On the commuting route from home to the company, the terminal device resides in N cells, namely, cell A, cell B, cell C, ..., cell P. The signal quality of the terminal device in these N historically resident cells in the past 5 days can be collected to evaluate the signal quality of the N cells. After the signal quality of these cells is evaluated, the cell type corresponding to each cell can be determined and stored.

[0075] In some embodiments, the cell types of the current resident cell and the associated cell may be stored in a preset database. Thus, when acquiring the associated cell corresponding to the current resident cell, the cell types of the current resident cell and the associated cell may be directly acquired from the preset database.

[0076] Of course, in other embodiments, the cell types of the current resident cell and the associated cell may also be stored in other databases. In this way, after obtaining the associated cell corresponding to the current resident cell from the preset database, the cell type of the current resident cell and the cell type of the associated cell may be obtained from other databases.

[0077] In some embodiments, when the cell type of the future cell is a poor cell type, there are multiple situations. For example, if the terminal device cannot directly use the network after entering the future cell (for example, it is disconnected from the network, the terminal device drops from a higher-speed network connection to a lower-speed network, such as from a 4G network or a 5G network to a 2G network or a 3G network, etc.), in this case, the cell type of the future cell can be determined to be a poor cell.

[0078] Alternatively, after the terminal device enters the future cell, the network quality on a certain wireless access technology RAT is very poor. For example, after entering the future cell, the network quality of the terminal device on the 5G cell is very poor. After turning off the 5G network, the network quality on the 4G cell is very good. In this case, the cell type of the future cell can also be determined as a poor cell.

[0079] Alternatively, after entering the future cell, the terminal device can still use the 4G network or the 5G network, but the network quality on these two RATs is very poor. In this case, the cell type of the future cell can also be determined as a poor cell.

[0080] In the embodiment of the present application, there is no limitation on the implementation method of obtaining the current information to be recommended according to the cell types of the current resident cell and the associated cells.

[0081] For example, in some embodiments, when the cell type of the current cell is an excellent cell, and the cell type of the future cell is a poor cell, and the terminal device is less than a preset threshold value after a preset time from the current moment, it is determined that the current information to be recommended is the information of the current cell and the future cell.

[0082] Here, there is no limitation on the value of the preset threshold. For example, in some embodiments, the preset threshold may be 30 seconds.

[0083] That is, when it is determined that the signal quality of the current resident cell is good, and the signal quality of the future cell corresponding to the current resident cell is poor, it can be determined whether the time required for the terminal device to enter the future cell after the current moment is less than the preset threshold. If the time required for the terminal device to enter the future cell after the current moment is less than the preset threshold (such as 30 seconds), it can be determined that the terminal device is about to enter the coverage of the future cell with poor signal quality. Based on this, it can be determined that the information to be recommended includes information about the current resident cell and the future cell.

[0084] In this way, the terminal device can continue to stay in the current cell with better signal quality according to the recommended information, and avoid future cells with poor signal quality in advance, thereby increasing the probability of the terminal device staying in a good cell and reducing the probability of the terminal device staying in a poor cell, thereby improving the user's network experience.

[0085] In some embodiments, when the cell type of the current cell is an excellent cell, and the cell type of the future cell is a poor cell, and the terminal device determines that the current information to be recommended is the information of the current cell when the preset time after the current moment is greater than or equal to a preset threshold.

[0086] That is to say, when it is determined that the signal quality of the current resident cell is good, and the signal quality of the future cell corresponding to the current resident cell is poor, it can be determined whether the time required for the terminal device to enter the future cell after the current moment is less than the preset threshold. If the time required for the terminal device to enter the future cell after the current moment is greater than or equal to the preset threshold (such as 30 seconds), it is possible that the terminal device has left the coverage of the current resident cell and entered the coverage of the new cell when entering the coverage of the future cell. It is necessary to re-execute the above method to re-determine the associated cell corresponding to the new cell, that is, the future cell in the associated cell corresponding to the new cell is a different cell from the future cell determined this time, and therefore, the future cell determined this time may not be recommended. Based on this, it can be determined that the information to be recommended includes information about the current resident cell.

[0087] In this way, the terminal device can continue to reside in the current resident cell with good signal quality according to the information to be recommended, thereby increasing the probability of the terminal device residing in a good cell and improving the user's network experience.

[0088] In some embodiments, when the cell type of the neighboring cell of the currently resident cell is an excellent cell, and the cell type of the currently resident cell is a poor cell, it is determined that the current information to be recommended is the information of the neighboring cell.

[0089] That is to say, when it is determined that the signal quality of the neighboring cell of the current resident cell is good, or the signal quality of the current resident cell is poor, it can be determined that the information to be recommended includes the information of the neighboring cell. In this way, the terminal device can switch cells in advance according to the information to be recommended, such as switching from the current resident cell with poor signal quality to the neighboring cell with good signal quality, thereby improving the network quality of the terminal device and improving the user experience.

[0090] In some embodiments, when the cell type of the neighboring cell is an excellent cell, and the cell type of the future cell is a poor cell, and the terminal device determines that the current information to be recommended is the information of the neighboring cell and the future cell when the preset time after the current moment is less than a preset threshold.

[0091] That is, when it is determined that the signal quality of the neighboring cell of the current resident cell is good, and the signal quality of the future cell corresponding to the current resident cell is poor, it can be determined whether the time required for the terminal device to enter the future cell after the current moment is less than the preset threshold. If the time required for the terminal device to enter the future cell after the current moment is less than the preset threshold (such as 30 seconds), it can be determined that the terminal device is about to enter the coverage of the future cell with poor signal quality. Based on this, it can be determined that the information to be recommended includes information of the current resident cell and the future cell.

[0092] Furthermore, in some embodiments, based on the above, it can also be determined whether the current resident cell of the terminal device is a superior cell. If the current resident cell is a superior cell, it can be determined that the information to be recommended includes information of the current resident cell, neighboring cells and future cells.

[0093] In this way, the terminal device can continue to stay in the current cell or switch to a neighboring cell with better signal quality based on the recommended information, and avoid future cells with poor signal quality in advance, thereby increasing the probability of the terminal device staying in a good cell and reducing the probability of the terminal device staying in a poor cell, thereby improving the user's network experience.

[0094] In some embodiments, when the cell type of the currently resident cell is an excellent cell or the cell type of the neighboring cell is an excellent cell, it is determined that the current information to be recommended is information of the currently resident cell or the neighboring cell.

[0095] Here, in the case that the cell type of the currently resident cell is an excellent cell, the information of the currently resident cell may be directly recommended so that the terminal device continues to reside in the currently resident cell.

[0096] When the cell type of the neighboring cell of the current resident cell is an excellent cell, the neighboring cell can be directly determined as the cell in the current recommended information, so that the terminal device can switch to the neighboring cell in advance when the current resident cell is a poor cell.

[0097] Alternatively, in some embodiments, the terminal device may also compare the signal quality of the current cell and the neighboring cell when the current cell is a superior cell and the neighboring cell is a superior cell, so that the terminal device can switch to the cell with better signal quality in advance, thereby increasing the probability of the terminal device staying in the superior cell and improving the user experience.

[0098] In some embodiments, when the cell type of the current resident cell is an excellent cell or the cell type of the neighboring cell is an excellent cell, after determining that the current information to be recommended is the information of the current resident cell or the neighboring cell, it is possible to continue waiting for the next cell change. That is, the next resident cell is reacquired at a preset interval (such as 5 seconds), and the associated cell associated with the next resident cell is searched from the preset database according to the cell parameters of the next cell; and then the next information to be recommended is determined according to the next resident cell and the associated cell, so that the terminal device performs a cell switching operation according to the next information to be recommended.

[0099] In some embodiments, when the cell type of the current resident cell is a poor cell, the current information to be recommended may be determined to be the current resident cell. In this way, the terminal device can learn that the signal quality of the current resident cell is poor, so as to avoid the poor cell in advance.

[0100] In some embodiments, when the cell type of the future cell is a poor cell and the terminal device is less than a preset threshold after the current moment, the current information to be recommended is determined to be a future cell. That is, if the time required for the terminal device to enter the future cell after the current moment is less than a preset threshold (such as 30 seconds), it can be determined that the terminal device is about to enter the coverage of the future cell with poor signal quality. In this way, the terminal device can be informed in advance that the signal quality of the future cell to be reached is poor, so as to avoid the future cell with poor signal quality in advance.

[0101] In some embodiments, when the cell type of the current cell is a poor cell, the cell type of the future cell is a poor cell, and the terminal device determines that the current information to be recommended is the information of the current cell and the future cell when the preset time after the current moment is less than a preset threshold.

[0102] That is to say, when the signal quality of the current resident cell is poor, the signal quality of the future cell is also poor, and the terminal device is about to enter the coverage of the future cell with poor signal quality, it can be determined that the current recommended information includes information of the current resident cell and the future cell. In this way, the terminal device can avoid cells with poor signal quality in advance based on the current recommended information obtained, increase the probability of staying in a good cell, and improve user experience.

[0103] In some embodiments, when the cell type of the current cell is a poor cell, the cell type of the future cell is a poor cell, and the terminal device determines that the current information to be recommended is the information of the current cell when the preset time after the current moment is greater than or equal to a preset threshold.

[0104] That is to say, when it is determined that the signal quality of the current resident cell is poor, and the signal quality of the future cell corresponding to the current resident cell is poor, it can be determined whether the time required for the terminal device to enter the future cell after the current moment is less than the preset threshold. If the time required for the terminal device to enter the future cell after the current moment is greater than or equal to the preset threshold (such as 30 seconds), it is possible that when the terminal device enters the coverage of the future cell, it has left the coverage of the current resident cell and entered the coverage of the new cell. It is necessary to re-execute the above method to re-determine the associated cell corresponding to the new cell, that is, the future cell in the associated cell corresponding to the new cell is a different cell from the future cell determined this time, and therefore, no recommendation can be made for the future cell determined this time. Based on this, it can be determined that the information to be recommended includes the information of the current resident cell. In this way, the terminal device can be informed that the signal quality of the current resident cell is poor, so as to avoid the poor cell in advance.

[0105] In an embodiment of the present application, after obtaining the current information to be recommended, the terminal device can perform cell switching according to the current information to be recommended.

[0106] Here, there is no limitation on the way in which the terminal device switches cells according to the current information to be recommended. For example, the terminal device may switch to a single superior cell when the current information to be recommended obtained includes a single superior cell; or the terminal device may switch to a superior cell with better signal quality among multiple superior cells when the current information to be recommended obtained includes multiple superior cells; or the terminal device may still reside in the current resident cell when the current information to be recommended obtained does not include a superior cell, until the cell is switched again when the information to be recommended obtained again includes a superior cell.

[0107] By implementing the above embodiment, the current information to be recommended can be determined according to different cell types, so that the terminal device can switch networks in advance according to the current information to be recommended, thereby increasing the probability of staying in a good cell and reducing the probability of staying in a bad cell.

[0108] In an embodiment of the present application, when the terminal device is in a target scenario where the cell switching frequency is greater than or equal to a preset frequency threshold, the associated cells of the current cell are obtained from a preset database based on the current cell of the terminal device. The associated cells include neighboring cells and future cells of the current cell, and the preset database contains the association relationship between each cell in all lines under the target scenario and the corresponding associated cells; subsequently, the terminal device can obtain the information to be recommended based on whether the current cell and the associated cells are of superior cell type or inferior cell type, so as to perform cell switching based on the information to be recommended.

[0109] In this way, the cell switching of the terminal device can be performed in advance according to different information to be recommended, thereby increasing the probability of the terminal device staying in a good cell, reducing the probability of the terminal device staying in a bad cell, and improving the user network experience.

[0110] The following describes an exemplary application of the embodiments of the present application in a practical application scenario.

[0111] Figure 5 This is the overall process of the cell switching method provided in the embodiment of the present application. Figure 5 As shown, the method includes the following contents:

[0112] When the terminal device recognizes that it is currently in a high-speed rail or subway line based on the cell information of multiple cells it passes through, it can query the knowledge graph database content based on the changes in the cell identification information and make different recommendations based on the different cell information queried. The specific process is as follows:

[0113] (1) When a cell change is detected, the knowledge graph database is queried and the process proceeds to step (2);

[0114] (2) The terminal device searches the database according to the current resident serving cell to obtain a query result, which includes the cell types of the current resident serving cell, neighboring cells of the current resident serving cell, and future cells. The cell types include an excellent cell type and a poor cell type.

[0115] If the query result contains good cells and bad cells, go to step (3);

[0116] If the query result contains only the best cells, go to step (4);

[0117] If the query result contains only poor cells, go to step (5);

[0118] (3) If the query result is:

[0119] (a) If the cell type of the current serving cell is an excellent cell and the cell type of the future cell is a poor cell, proceed to step (6);

[0120] (b) If the cell type of the neighboring cell of the current serving cell is an excellent cell, and the cell type of the current serving cell is a poor cell, the neighboring cell information is recommended and the process goes to step (7);

[0121] (c) If the cell type of the neighboring cell of the current serving cell is an excellent cell and the cell type of the future cell is a poor cell, the neighboring cell and future cell information are recommended and the process goes to step (6);

[0122] (4) If the query result shows that the cell type of the current serving cell is an excellent cell or the cell type of the neighboring cell of the current serving cell is an excellent cell, the current serving cell information or the neighboring cell is directly recommended, and the process goes to step (7);

[0123] (5) If the query result shows that the cell type of the current serving cell is a poor cell, directly recommend the current serving cell information and go to step (7); if the query result shows that the cell type of the future cell is a poor cell, that is, after x seconds, the user will enter a poor cell and stay in this cell for y seconds, then go to step (6);

[0124] Step (6) If the cell type of the future cell is a poor cell, and the time from the current resident cell to the poor cell is less than a preset time (e.g., less than 30 seconds), the recommended information includes the information of the future cell; otherwise, the information of the future cell is not included, other information is recommended, and step (7) is entered;

[0125] Step (7): Stop and wait for the next cell change.

[0126] In an embodiment of the present application, in the driving status of the route for which information has been collected, the network can be switched in advance according to the recommended information, the probability of staying in a good cell can be increased, and the probability of staying in a bad cell can be reduced. Different strategies can be made through different recommended information to improve the user's network experience.
