[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0040] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions. For example, the first reported data, second reported data and third reported data involved in this application are all obtained with full authorization.

[0041] Please refer to Figure 1 , which shows a schematic diagram of an implementation environment of a cell recommendation method provided by an exemplary embodiment of the present application. The implementation environment includes: a server 101 and multiple mobile terminals 102; a recommendation application provided by the server 101 is installed in the mobile terminal 102, and the mobile terminal 102 implements functions such as data transmission and information interaction with the server 101 through the recommendation application. For example, multiple mobile terminals 102 send reported data to the server 101 through the recommendation application, and the server 101 generates a cell map based on the reported data using the knowledge graph technology, and then recommends cells to the mobile terminal 102 based on the cell map.

[0042] For ease of distinction, the multiple mobile terminals 102 include a first mobile terminal 102 and a second mobile terminal 102. The first mobile terminal 102 sends first reported data to the server 101 through a recommendation application; the server 101 generates a cell map based on the first reported data, and then recommends a cell to the second mobile terminal 102 based on the cell map. The specific process is described in detail in subsequent embodiments.

[0043] In some embodiments, the implementation environment further includes a network device 103, and the network device 103 includes at least one cell. The mobile terminal 102 performs data communication with the network device 103 of a cell by accessing the cell.

[0044] The mobile terminal 102 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), etc. For the convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as mobile terminals 102. In the embodiments of the present application, "UE" is used to represent "mobile terminal 102" in some places.

[0045] The network device 103 is a device for providing wireless communication services to the mobile terminal 102. The network device 103 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the 5G wireless air interface technology (New Radio, NR) system, it is called a 5G base station (gNodeB or gNB). With the evolution of communication technology, the name "base station" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication services to the mobile terminal 102 are collectively referred to as network devices 103.

[0046] Please refer to Figure 2 , which shows a flowchart of a cell recommendation method provided by an exemplary embodiment of the present application. The method may include the following steps:

[0047] Step 201: The server receives first reporting data from a first mobile terminal, the first reporting data including cell information and transmission quality information of a first cell accessed by the first mobile terminal, the transmission quality information being used to indicate transmission quality of data transmission between the first mobile terminal and a network device of the first cell.

[0048] The first cell may be a cell currently accessed by the first mobile terminal, or may be a cell historically accessed by the first mobile terminal. The cell information of the first cell is used to represent the information of the first cell; for example, the cell information of the first cell includes the cell identifier (CID) of the first cell, the carrier frequency (ARFCN) used to transmit wireless signals in the first cell, and the physical cell identifier (PCI) of the first cell. The transmission quality information of the first cell is used to represent the transmission quality of data transmission between the first mobile terminal and the network device of the first cell; for example, the transmission quality information of the first cell includes a first transmission rate, and the first transmission rate includes at least one of a first uplink transmission rate at which the first mobile terminal transmits data to the network device of the first cell and a first downlink transmission speed at which the first mobile terminal receives data from the network device of the first cell. The first reported data may also include a timestamp for collecting the first reported data.

[0049] In an embodiment of the present application, the transmission quality information can reflect the actual network situation of the first mobile terminal. Therefore, the first mobile terminal includes the transmission quality information as a key indicator in the first reported data, and can provide the server with accurate network conditions, thereby improving the accuracy of the cell map determined based on the first reported data, and then improving the accuracy of the cell recommended for the second mobile terminal based on the cell map, that is, it can recommend a cell with better actual network conditions to the second mobile terminal, thereby improving user perception.

[0050] In some embodiments, when the first mobile terminal switches to a certain cell, it collects and sends the reported data to the server once; accordingly, when the first mobile terminal accesses the first cell, the first mobile terminal collects the first reported data and then sends the first reported data to the server, thereby saving the collection resources and transmission resources of the first mobile terminal. In other embodiments, the first mobile terminal periodically collects and sends the reported data to the server; accordingly, the first mobile terminal periodically collects the first reported data; and after the first mobile terminal collects the first reported data, it sends the first reported data to the server.

[0051] In an embodiment of the present application, since the transmission quality information of the first mobile terminal at each timestamp may be different, the first mobile terminal periodically collects and sends the first reported data to the server, which can ensure that the server can obtain the latest first reported data, thereby ensuring the accuracy of the cell map subsequently determined based on the first reported data, thereby improving the effectiveness of cell recommendations based on the cell map.

[0052] Step 202: The server updates the cell map based on the cell information and transmission quality information of the first cell. The cell map includes the cell entities corresponding to the cell information, the entity attributes corresponding to the transmission quality information, and the entity relationships between the cell entities. The entity relationships are used to characterize the access order of the cells.

[0053] When the server has generated a cell map, the server updates the cell map based on the cell information and transmission quality information of the first cell; when the server has not yet generated a cell map, the server generates a cell map based on the cell information and transmission quality information of the first cell.

[0054] In one possible implementation, the server may generate a cell map based on the cell information and transmission quality information of the first cell. The server may create a cell map, add a cell entity corresponding to the cell information of the first cell to the cell map, and determine the transmission quality information of the first cell as an entity attribute of the cell entity.

[0055] In a possible implementation manner, the server updates the cell map based on the cell information and transmission quality information of the first cell through the following steps 2021-2022, including:

[0056] Step 2021: The server determines second reporting data of the first mobile terminal, where the second reporting data includes cell information and transmission quality information of a fourth cell historically accessed by the first mobile terminal.

[0057] The cell information of the fourth cell is used for information of the fourth cell; for example, the cell information of the fourth cell includes the CID of the fourth cell, the carrier frequency used to transmit wireless signals in the fourth cell, and the PCI of the fourth cell. The transmission quality information of the fourth cell is used to indicate the transmission quality of data transmission between the first mobile terminal and the network device of the fourth cell; for example, the transmission quality information of the fourth cell includes a second transmission rate, and the second transmission rate includes at least one of a second uplink transmission rate at which the first mobile terminal transmits data to the network device of the fourth cell and a second downlink transmission speed at which the first mobile terminal receives data from the network device of the fourth cell. The second reported data may also include a timestamp for collecting the second reported data.

[0058] Each time the server receives the reported data from the mobile terminal, it will associate and store the terminal identifier and the reported data of the first mobile terminal; therefore, in this step, the server obtains the reported data associated with the terminal identifier based on the terminal identifier of the first mobile terminal, and the obtained reported data is the second reported data.

[0059] Step 2022: The server updates the cell map based on the cell information and transmission quality information of the first cell and the cell information and transmission quality information of the fourth cell.

[0060] In a possible implementation, this step may be implemented by following steps 20221-20225, including:

[0061] Step 20221: Based on the cell information of the first cell and the cell information of the fourth cell, the server searches the cell map for a third cell entity corresponding to the first cell and a fourth cell entity corresponding to the fourth cell.

[0062] The cell map includes cell entities corresponding to the cell information; accordingly, the steps of searching the third cell entity corresponding to the first cell and the fourth cell entity corresponding to the fourth cell in the cell map based on the cell information of the first cell and the cell information of the fourth cell may be: the server searches the cell information of the first cell in the cell map; when the cell information of the first cell is found, it is determined that the third cell entity corresponding to the first cell is found; when the cell information of the first cell is not found, it is determined that the third cell entity corresponding to the first cell is not found; the server searches the cell information of the fourth cell in the cell map; when the cell information of the fourth cell is found, it is determined that the fourth cell entity corresponding to the fourth cell is found; when the cell information of the fourth cell is not found, it is determined that the fourth cell entity corresponding to the fourth cell is not found.

[0063] If the third cell entity is found but the fourth cell entity is not found, execute step 20222; if the third cell entity and the fourth cell entity are found, execute step 20223; if the third cell entity is not found but the fourth cell entity is found, execute step 20224; if the third cell entity and the fourth cell entity are not found, execute step 20225.

[0064] Step 20222: When the third cell entity is found but the fourth cell entity is not found, the server adds the fourth cell entity to the cell map, and sets the access order of the fourth cell entity to the third cell entity. Then, based on the transmission quality information of the first cell, the server updates the entity attributes of the third cell entity, and determines the transmission quality information of the fourth cell as the entity attributes of the fourth cell entity.

[0065] After the server sets the access order of the fourth cell entity to the third cell entity, it can be understood that the fourth cell entity is set as the subsequent cell entity of the third cell entity in the cell map, which means that the mobile terminal first accesses the cell corresponding to the third cell entity, and then accesses the cell corresponding to the fourth cell entity.

[0066] The step after the server sets the access order of the fourth cell entity to the third cell entity may be: the server adds a connection line between the third cell entity and the fourth cell entity, and sets the direction of the connection line from the third cell entity to the fourth cell entity. For example, please refer to Figure 3 The cell map includes cell entity 1, cell entity 2 and cell entity 3, and cell entity 3 is the third cell entity. The server adds cell entity 4 to the cell map, and cell entity 3 points to cell entity 4, and determines the transmission quality information of the fourth cell as the entity attribute of cell entity 4.

[0067] In a possible implementation manner, the step of updating the entity attribute of the third cell entity by the server based on the transmission quality information of the first cell may be implemented by any of the following implementation manners:

[0068] A first implementation manner: the server updates the entity attributes of the third cell entity to the transmission quality information of the first cell.

[0069] In an embodiment of the present application, since the transmission quality information of the first cell is currently reported by the first mobile terminal, that is, the transmission quality information of the first cell is the latest transmission quality information of the first cell; therefore, the server updates the entity attributes of the third cell entity to the transmission quality information of the first cell, which can improve the effectiveness of the entity attributes of the third cell entity.

[0070] A second implementation manner: the server performs weighted summation on the transmission quality information of the first cell and the transmission quality information corresponding to the entity attributes of the third cell entity to obtain updated entity attributes of the third cell entity.

[0071] For example, the transmission quality information of the first cell includes a first transmission rate, and the transmission quality information corresponding to the entity attributes of the third cell entity includes a third transmission rate; the server performs a weighted summation on the first transmission rate and the third transmission rate to obtain a fourth transmission rate, and updates the entity attributes of the third cell entity to the fourth transmission rate.

[0072] In an embodiment of the present application, the entity attributes of the third cell entity are the transmission quality information of the first cell reported by other mobile terminals, and the transmission quality information of the first cell may be inaccurate due to network instability; therefore, the server performs weighted summation of the transmission quality information of the first cell reported by the first mobile terminal and the transmission quality information corresponding to the entity attributes of the third cell entity to obtain the latest entity attributes of the third cell entity, thereby improving the reliability of the entity attributes of the third cell entity.

[0073] A third implementation method: the server determines the marking timestamp of the entity attributes of the third cell entity and the receiving timestamp of the transmission quality information of the first cell, and updates the entity attributes of the third cell entity based on the marking timestamp, the receiving timestamp and the transmission quality information of the first cell.

[0074] The server determines the time interval between the receiving timestamp and the marking timestamp; if the time interval is greater than the preset time interval, the entity attribute of the third cell entity is updated to the transmission quality information of the first cell; if the time interval is not greater than the preset time interval, the transmission quality information of the first cell and the transmission quality information corresponding to the entity attribute of the third cell entity are weighted summed to obtain the updated entity attribute of the third cell entity. Alternatively, if the time interval is not greater than the preset time interval, the server may not update the entity attribute of the third cell entity.

[0075] In the embodiment of the present application, when the time interval is large, it means that the entity attributes of the third cell entity cannot reflect the real network situation of the first cell; therefore, the server updates the entity attributes of the third cell entity to the transmission quality information of the first cell, which can improve the validity of the entity attributes of the third cell entity. When the time interval is small, the server performs a weighted summation of the transmission quality information of the first cell reported by the first mobile terminal and the transmission quality information corresponding to the entity attributes of the third cell entity to obtain the latest entity attributes of the third cell entity, thereby improving the reliability of the entity attributes of the third cell entity.

[0076] Step 20223: When the third cell entity and the fourth cell entity are found, the server sets the access order of the fourth cell entity to the third cell entity in the cell map, and then updates the entity attributes of the third cell entity based on the transmission quality information of the first cell, and updates the entity attributes of the fourth cell entity based on the transmission quality information of the fourth cell.

[0077] Before the server sets the access order of the fourth cell entity to after the third cell entity in the cell map, the server first determines the entity relationship between the third cell entity and the fourth cell entity in the cell map; when the entity relationship between the third cell entity and the fourth cell entity is that the access order of the fourth cell entity is after the third cell entity, directly execute the steps of updating the entity attributes of the third cell entity based on the transmission quality information of the first cell, and updating the entity attributes of the fourth cell entity based on the transmission quality information of the fourth cell; when the entity relationship between the third cell entity and the fourth cell entity is not that the access order of the fourth cell entity is after the third cell entity, the server sets the access order of the fourth cell entity to after the third cell entity, which can be understood as setting the fourth cell entity as a subsequent cell entity of the third cell entity in the cell map, which means that the mobile terminal first accesses the cell corresponding to the third cell entity, and then accesses the cell corresponding to the fourth cell entity.

[0078] For example, please refer to Figure 3 , the cell map includes cell entity 3 (the third cell entity) and cell entity 4 (the fourth cell entity), but cell entity 4 is not the subsequent cell entity of cell entity 3; therefore, the server adds a connection line between cell entity 3 and cell entity 4, and sets the direction of the connection line from cell entity 3 to cell entity 4.

[0079] The process of the server updating the entity attributes of the third cell entity based on the transmission quality information of the first cell is the same as the process of the server updating the entity attributes of the third cell entity based on the transmission quality information of the first cell in step 20222, and will not be repeated here.

[0080] The step of updating the entity attributes of the fourth cell entity based on the transmission quality information of the fourth cell by the server can be implemented in any of the following ways: the server updates the entity attributes of the fourth cell entity to the transmission quality information of the fourth cell. Alternatively, the server performs a weighted summation of the transmission quality information of the fourth cell and the transmission quality information corresponding to the entity attributes of the fourth cell entity to obtain the updated entity attributes of the fourth cell entity. Alternatively, the server determines the marking timestamp of the entity attributes of the fourth cell entity and the receiving timestamp of the transmission quality information of the fourth cell, and updates the entity attributes of the fourth cell entity based on the marking timestamp, the receiving timestamp and the transmission quality information of the fourth cell.

[0081] Step 20224: When the third cell entity is not found but the fourth cell entity is found, the server adds the third cell entity to the cell map, sets the access order of the third cell entity before the fourth cell entity, determines the transmission quality information of the first cell as the entity attribute of the third cell entity, and updates the entity attribute of the fourth cell entity based on the transmission quality information of the fourth cell.

[0082] The server setting the access order of the third cell entity before the fourth cell entity can be understood as setting the third cell entity as the preceding cell entity of the fourth cell entity in the cell map, which means that the mobile terminal first accesses the cell corresponding to the third cell entity and then accesses the cell corresponding to the fourth cell entity.

[0083] The step before the server sets the access order of the third cell entity to the fourth cell entity may be: the server adds a connection line between the third cell entity and the fourth cell entity, and sets the direction of the connection line from the third cell entity to the fourth cell entity. Figure 3 The server adds cell entity 3 (the third cell entity) in the cell map, and cell entity 3 points to cell entity 4, and determines the transmission direction information of the first cell as the entity attribute of cell entity 3.

[0084] The step in which the server updates the entity attributes of the fourth cell entity based on the transmission quality information of the fourth cell is the same as the step in which the server updates the entity attributes of the fourth cell entity based on the transmission quality information of the fourth cell in step 20223, and will not be repeated here.

[0085] Step 20225: When the third cell entity and the fourth cell entity are not found, the server adds the third cell entity and the fourth cell entity to the cell map, and sets the access order of the fourth cell entity to the third cell entity. Thereafter, the server determines the transmission quality information of the first cell as the entity attribute of the third cell entity, and determines the transmission quality information of the fourth cell as the entity attribute of the fourth cell entity.

[0086] For example, please refer to Figure 3 The cell map includes cell entity 1 and cell entity 2. The server adds cell entity 3 and cell entity 4 in the cell map, and cell entity 3 points to cell entity 4. The transmission quality information of the first cell is determined as the entity attribute of cell entity 3, and the transmission quality information of the fourth cell is determined as the entity attribute of cell entity 4.

[0087] In an embodiment of the present application, the server updates the cell map based on the first reported data, thereby realizing automatic updating of the cell map by using data analysis, and then automatically recommending neighboring cells, thereby reducing manual maintenance costs.

[0088] Step 203: When the second mobile terminal has a demand for cell recommendation, the server determines a cell recommendation list based on the cell map, where the cell recommendation list includes cell information of at least one second cell.

[0089] In one possible implementation, the server periodically determines the cell recommendation list; accordingly, in this step, when a preset period is reached, the server determines that the second mobile terminal has a cell recommendation demand. In another possible implementation, when the server receives a recommendation request from the second mobile terminal, it determines that the second mobile terminal has a cell recommendation demand.

[0090] Among them, the step of the server determining the cell recommendation list based on the cell map can be: the server determines at least one candidate cell entity path based on the entity relationship between the cell entities in the cell map, the candidate cell entity path includes multiple cell entities, and determines the cell recommendation list based on the entity attributes of the multiple cell entities included in the at least one candidate cell entity path.

[0091] Step 204: The server sends a cell recommendation list to the second mobile terminal.

[0092] The second mobile terminal receives the cell recommendation list sent by the server, and can then perform cell switching based on the cell information of at least one second cell included in the cell recommendation list.

[0093] In an embodiment of the present application, on the one hand, the cell map is updated based on the first reported data of the first mobile terminal; therefore, the cell map is constructed based on dynamic data, and cell recommendations based on the cell map can achieve dynamic optimal cell recommendations and improve the accuracy of cell recommendations. On the other hand, the cell map includes cell entities corresponding to cell information, entity attributes corresponding to transmission quality information, and entity relationships between cell entities, and the entity relationships are used to characterize the access order of cells; therefore, the cell map can reflect the correlation and transmission quality between cells, and cell recommendations based on the small map can combine the correlation and transmission quality between cells to make cell recommendations, thereby improving the accuracy of cell recommendations. It can be seen that the embodiment of the present application can improve the accuracy of cell recommendations.

[0094] Please refer to Figure 4 , which shows a flowchart of a cell recommendation method provided by an exemplary embodiment of the present application. The method may include the following steps:

[0095] Step 401: The second mobile terminal receives a cell recommendation list sent by the server, where the cell recommendation list includes cell information of at least one second cell. The cell recommendation list is determined by the server based on a cell map, where the cell map includes cell entities corresponding to the cell information, entity attributes corresponding to the transmission quality information, and entity relationships between cell entities, where the entity relationships are used to characterize the access order of the cells.

[0096] In a possible implementation, the server periodically determines a cell recommendation list and sends the cell recommendation list to the second mobile terminal; at this time, the second mobile terminal may not need to perform cell switching; therefore, after receiving the cell recommendation list sent by the server, the second mobile terminal stores the cell recommendation list. In the case where the second mobile terminal has locally stored the cell recommendation list, the second mobile terminal updates the stored cell recommendation list to the currently received cell recommendation list.

[0097] In another possible implementation, the second mobile terminal triggers the server to send a cell recommendation list to the second mobile terminal; at this time, the second mobile terminal needs to perform a cell switch; therefore, after receiving the cell recommendation list sent by the server, the second mobile terminal can directly execute step 402.

[0098] Step 402: When the second mobile terminal has a cell switching demand, the second mobile terminal determines the cell information of the target cell from the cell recommendation list, where the target cell is the cell to which the second mobile terminal is to switch.

[0099] In one possible implementation, when the second mobile terminal switches to a new cell (such as the third cell), it is necessary to determine the target cell, and then directly switch to the target cell when the signal quality of the third cell is poor; accordingly, when the second mobile terminal switches to a new cell (such as the third cell), it is determined that the second mobile terminal has a cell switching demand. In another possible implementation, when the signal quality of the wireless signal between the second mobile terminal and the network device of the third cell currently accessed is lower than a preset quality threshold, it is determined that the second mobile terminal has a cell switching demand. Among them, the step of the second mobile terminal determining the cell information of the target cell from the cell recommendation list is described in detail in subsequent embodiments.

[0100] Step 403: The second mobile terminal switches from the third cell currently accessed by the second mobile terminal to the target cell based on the cell information of the target cell.

[0101] The second mobile terminal disconnects the network connection with the network device of the third cell, and establishes a network connection with the network device of the target cell based on the cell information of the target cell.

[0102] In one possible implementation, the timing for determining the cell information of the target cell in step 402 is when the second mobile terminal switches to a new cell (such as a third cell). In this step, the second mobile terminal does not directly switch the cell, but periodically determines the signal quality of the wireless signal between the second mobile terminal and the network device of the third cell. When the signal quality of the wireless signal is lower than a preset quality threshold, the second mobile terminal switches from the third cell to the target cell based on the cell information of the target cell. In another possible implementation, the timing for determining the cell information of the target cell in step 402 is when the signal quality of the wireless signal between the second mobile terminal and the network device of the third cell is lower than a preset quality threshold. In this step, the second mobile terminal directly switches from the third cell to the target cell based on the cell information of the target cell.

[0103] The second mobile terminal will also report relevant information of the third cell to the server so that the server can update the cell map based on the relevant information of the third cell; the process includes: the second mobile terminal obtains the cell information and transmission quality information of the third cell; and sends third reporting data to the server, the third reporting data including the cell information and transmission quality information of the third cell, so that the server can update the cell map based on the cell information and transmission quality information of the third cell.

[0104] Among them, the process of the server updating the cell map based on the cell information and transmission quality information of the third cell is similar to the process of the server updating the cell map based on the cell information and transmission quality information of the first cell, and will not be repeated here.

[0105] In an embodiment of the present application, since the cell recommendation list is determined by the server based on the cell map, and the cell map is constructed based on dynamic data, and the cell map can reflect the correlation and transmission quality between cells; therefore, the cell recommendation list recommended by the server is more accurate, so that the transmission quality of the target cell determined from the cell recommendation list is higher, thereby improving the communication quality of accessing the target cell for data communication.

[0106] Please refer to Figure 5 , which shows a flowchart of a cell recommendation method provided by an exemplary embodiment of the present application. In the embodiment of the present application, an example is given in which a server periodically determines a cell recommendation list and sends the cell recommendation list to a second mobile terminal. The method may include the following steps:

[0107] Step 501: The server receives first reported data from a first mobile terminal, where the first reported data includes cell information and transmission quality information of a first cell accessed by the first mobile terminal, where the transmission quality information is used to indicate the transmission quality of data transmission between the first mobile terminal and a network device of the first cell.

[0108] In some embodiments, this step is the same as step 201 and will not be repeated here.

[0109] Step 502: The server updates the cell map based on the cell information and transmission quality information of the first cell. The cell map includes the cell entities corresponding to the cell information, the entity attributes corresponding to the transmission quality information, and the entity relationships between the cell entities. The entity relationships are used to characterize the access order of the cells.

[0110] In some embodiments, this step is the same as step 202 and will not be repeated here.

[0111] Step 503: When the second mobile terminal has a cell recommendation demand, the server determines at least one candidate cell entity path based on the entity relationship between the cell entities in the cell map, and the candidate cell entity path includes multiple cell entities.

[0112] In a possible implementation, the server determines all candidate cell entity paths from the cell map. Accordingly, the server determines at least one candidate cell entity path based on the entity relationship between the cell entities in the cell map as follows: the server determines multiple candidate cell entities, the candidate cell entity is a cell entity that does not exist before the candidate cell entity (or the candidate cell entity is a cell entity that does not have a preceding cell entity); for any candidate cell entity, based on the entity relationship between the cell entities in the cell map, determines a candidate cell entity path with the candidate cell entity as the starting point.

[0113] For example, see Figure 6 , the cell map includes cell entity 1, cell entity 2, cell entity 3, cell entity 4, cell entity 5 and cell entity 6; the server determines multiple candidate cell entity paths including candidate cell entity path 1, candidate cell entity path 2 and candidate cell entity path 3 based on the entity relationship between the multiple cell entities in the cell map, the candidate cell entity path 1 is cell entity 1-cell entity 2-cell entity 3-cell entity 4, the candidate cell entity path 2 is cell entity 1-cell entity 5, and the candidate cell entity path 2 is cell entity 1-cell entity 6.

[0114] In another possible implementation, the server determines a candidate cell entity path of a city from a cell map. Accordingly, the server determines at least one candidate cell entity path based on the entity relationship between the cell entities in the cell map as follows: the server determines the area where the second mobile terminal is located; based on the area and the entity relationship between the cell entities in the cell map, at least one candidate cell entity path is determined, and the coverage of the cells corresponding to the multiple cell entities included in the at least one candidate cell entity path belongs to the area.

[0115] In a first implementation, the server first determines a plurality of candidate cell entity paths, and then deletes the candidate cell entity paths whose coverage range of the cell corresponding to the cell entity does not belong to the area range from the plurality of candidate cell entity paths; accordingly, the server determines at least one candidate cell entity path based on the entity relationship between the area range and the cell entity in the cell map, which may be:

[0116] The server determines multiple candidate cell entities, where a candidate cell entity is a cell entity that does not exist before the candidate cell entity (or the candidate cell entity is a cell entity that does not have a preceding cell entity); for any candidate cell entity, based on the entity relationship between the cell entities in the cell map, a candidate cell entity path with the candidate cell entity as the starting point is determined. Since there are multiple candidate cell entities, multiple candidate cell entity paths are determined; for any candidate cell entity path, if the coverage range of the cell corresponding to the cell entity included in the candidate cell entity path does not belong to the area range, the candidate cell entity path is deleted from the multiple candidate cell entity paths to obtain at least one candidate cell entity path.

[0117] For example, the server determines that three candidate cell physical paths are candidate cell physical path 1, candidate cell physical path 2 and candidate cell physical path 3. Since the coverage range of the cell corresponding to the cell entity included in candidate cell physical path 2 does not belong to the area range, candidate cell physical path 2 is deleted; therefore, the server finally determines two candidate cell physical paths, namely candidate cell physical path 1 and candidate cell physical path 3.

[0118] In a second implementation, the server first determines a plurality of candidate cell entity paths, and then deletes the cell entity whose coverage range of the corresponding cell does not belong to the area range from the plurality of candidate cell entity paths; accordingly, the server determines at least one candidate cell entity path based on the entity relationship between the area range and the cell entity in the cell map, which may be:

[0119] The server determines multiple candidate cell entities, where a candidate cell entity is a cell entity that does not exist before the candidate cell entity (or the candidate cell entity is a cell entity that does not have a preceding cell entity); for any candidate cell entity, based on the entity relationship between the cell entities in the cell map, a candidate cell entity path with the candidate cell entity as the starting point is determined. Since there are multiple candidate cell entities, multiple candidate cell entity paths are determined; for any candidate cell entity path, if the coverage range of the cell corresponding to the cell entity included in the candidate cell entity path does not belong to the area range, the cell entity is deleted from the candidate cell entity path to obtain at least one candidate cell entity path.

[0120] For example, the server determines that three candidate cell entity paths are candidate cell entity path 1, candidate cell entity path 2 and candidate cell entity path 3, and the coverage ranges of the cells corresponding to the cell entities included in candidate cell entity path 1 and candidate cell entity path 3 are both within the area, while candidate cell entity path 2 is cell entity 1-cell entity 2-cell entity 3, and the coverage ranges of the cells corresponding to cell entity 1 and cell entity 3 are respectively within the area, while the coverage range of the cell corresponding to cell entity 2 does not belong to the area, then the server deletes cell entity 2 in candidate cell entity path 2; therefore, the candidate cell entity paths finally determined by the server are candidate cell entity path 1, candidate cell entity path 3 and candidate cell entity path 2 after cell entity 2 is deleted.

[0121] Step 504: The server determines a target cell physical path from at least one candidate cell physical path based on the physical attributes of a plurality of cell entities included in the at least one candidate cell physical path.

[0122] In this step, the server needs to determine the cell with a higher transmission rate; therefore, a cell physical path consisting of cells with successively increasing transmission rates is selected from at least one candidate cell physical path; accordingly, this step can be: for any two adjacent cell entities in any candidate cell physical path, when the transmission quality represented by the physical attributes of the latter cell entity is higher than the transmission quality represented by the physical attributes of the former cell entity, the server determines the candidate cell physical path as the target cell physical path.

[0123] Step 505: The server generates a cell recommendation list based on the cell information of the second cell corresponding to the cell entity included in the target cell entity path.

[0124] In one possible implementation, the server composes a cell recommendation list with cell information of a second cell corresponding to a cell entity included in the target cell entity path, and in this implementation, the cell recommendation list includes cell information of at least one second cell. In another possible implementation, the server composes a cell recommendation list with the target cell entity path, and in this implementation, the cell recommendation list includes cell information of a second cell corresponding to a cell entity included in the target cell entity path, entity relationships between cell entities, and entity attributes of cell entities.

[0125] Step 506: The server sends the cell recommendation list to the second mobile terminal.

[0126] Step 507: The second mobile terminal receives the cell recommendation list sent by the server, and stores the cell recommendation list.

[0127] In the case that the second mobile terminal has stored the cell recommendation list locally, the second mobile terminal updates the stored cell recommendation list to the currently received cell recommendation list, so as to store the latest cell recommendation list.

[0128] Step 508: When the second mobile terminal has a cell switching requirement, the second mobile terminal searches for a fifth cell entity corresponding to the cell information of the third cell in the target cell entity path.

[0129] When the signal quality of the wireless signal between the second mobile terminal and the network device of the third cell is lower than the preset quality threshold, the second terminal determines that there is a cell switching request, and at this time, the second terminal searches for the fifth cell entity corresponding to the cell information of the third cell from the target cell entity path. If the fifth cell entity is found, step 509 is executed; if the fifth cell entity is not found, the second mobile terminal maintains the access state of the third cell; or, if the fifth cell entity is not found, the second mobile terminal searches for the fourth cell with the highest signal strength, and switches the second mobile terminal from the third cell to the fourth cell.

[0130] In an embodiment of the present application, when the fifth cell entity is not found, the second mobile terminal maintains the access state of the third cell, thereby reducing the frequency of cell switching and improving user experience.

[0131] Step 509: when the fifth cell entity is found, the second mobile terminal determines the cell information of the second cell corresponding to the sixth cell entity from the target cell entity path, and the sixth cell entity is a cell entity that is located after the fifth cell entity in the access sequence.

[0132] Based on the fifth cell entity, the mobile terminal determines a subsequent cell entity of the fifth cell entity, that is, a sixth cell entity, from the target cell entity path, and then determines cell information of a second cell corresponding to the sixth cell entity.

[0133] Step 510: The second mobile terminal determines the cell information of the second cell corresponding to the sixth cell entity as the cell information of the target cell.

[0134] Step 511: The second mobile terminal switches from a third cell currently accessed by the second mobile terminal to the target cell based on the cell information of the target cell.

[0135] In some embodiments, this step is the same as step 403 and will not be repeated here.

[0136] In an embodiment of the present application, the second mobile terminal switches from the third cell to the target cell, thereby enabling selection of the optimal neighboring cell and improving network performance.

[0137] In an embodiment of the present application, on the one hand, the cell map is updated based on the first reported data of the first mobile terminal; therefore, the cell map is constructed based on dynamic data, and cell recommendations based on the cell map can achieve dynamic optimal cell recommendations and improve the accuracy of cell recommendations. On the other hand, the cell map includes cell entities corresponding to cell information, entity attributes corresponding to transmission quality information, and entity relationships between cell entities, and the entity relationships are used to characterize the access order of cells; therefore, the cell map can reflect the correlation and transmission quality between cells, and cell recommendations based on the small map can combine the correlation and transmission quality between cells to make cell recommendations, thereby improving the accuracy of cell recommendations. It can be seen that the embodiment of the present application can improve the accuracy of cell recommendations.

[0138] Please refer to Figure 7 , which shows a flowchart of a cell recommendation method provided by an exemplary embodiment of the present application. In the embodiment of the present application, the second mobile terminal triggers the server to recommend a cell as an example for explanation. The method may include the following steps:

[0139] Step 701: The server receives first reporting data from a first mobile terminal, the first reporting data including cell information and transmission quality information of a first cell accessed by the first mobile terminal, the transmission quality information being used to indicate the transmission quality of data transmission between the first mobile terminal and a network device of the first cell.

[0140] In some embodiments, this step is the same as step 201 and will not be repeated here.

[0141] Step 702: The server updates the cell map based on the cell information and transmission quality information of the first cell. The cell map includes the cell entities corresponding to the cell information, the entity attributes corresponding to the transmission quality information, and the entity relationships between the cell entities. The entity relationships are used to characterize the access order of the cells.

[0142] In some embodiments, this step is the same as step 202 and will not be repeated here.

[0143] Step 703: When the second mobile terminal has a cell switching requirement, the second mobile terminal sends a recommendation request to the server, where the recommendation request carries cell information of a third cell currently accessed by the second mobile terminal.

[0144] In addition to carrying the cell information of the third cell, the recommendation request may also carry the transmission quality information of the third cell.

[0145] Step 704: The server receives the recommendation request sent by the second mobile terminal, and based on the cell information of the third cell, determines the first cell entity corresponding to the cell information of the third cell from the cell map.

[0146] Step 705: The server determines at least one candidate cell entity path based on the entity relationship between the first cell entity and the cell entities in the cell map, and the starting cell entity of the candidate cell entity path is the first cell entity.

[0147] The server determines at least one second cell entity whose access order is after the first cell entity in the cell map, and for any second cell entity, determines the path from the first cell entity to the second cell entity as the candidate cell entity path. For example, please continue to refer to Figure 3 , the first cell entity is cell entity 1, then there are three candidate cell entity paths determined, namely cell entity 1-cell entity 2, cell entity 1-cell entity 5, and cell entity 1-cell entity 6.

[0148] Step 706: The server determines a cell recommendation list based on entity attributes of multiple cell entities included in at least one candidate cell entity path.

[0149] For any second cell entity included in the candidate cell entity path, the second cell entity is a cell entity that is located after the first cell entity in the access order, and when the transmission quality represented by the entity attribute of the second cell entity is higher than the transmission quality represented by the entity attribute of the first cell entity, the server determines the cell information corresponding to the second cell entity as the cell information of the second cell; and adds the cell information of the second cell to the cell recommendation list. In addition, the server also adds the transmission quality information of the second cell to the cell list.

[0150] Step 707: The server sends the cell recommendation list to the second mobile terminal.

[0151] Step 708: The second mobile terminal receives the cell recommendation list, and based on the transmission quality information of at least one second cell included in the cell recommendation list, determines the cell information of the second cell with the highest transmission quality from the cell information of the at least one second cell.

[0152] In the embodiment of the present application, the second mobile terminal determines the cell information of the second cell with the highest transmission quality from the cell information of at least one second cell, thereby improving the quality of data communication after accessing the second cell.

[0153] Step 709: The second mobile terminal determines the determined cell information of the second cell as the cell information of the target cell.

[0154] Step 710: The second mobile terminal switches from a third cell currently accessed by the second mobile terminal to the target cell based on the cell information of the target cell.

[0155] In some embodiments, this step is the same as step 403 and will not be repeated here.

[0156] In an embodiment of the present application, on the one hand, the cell map is updated based on the first reported data of the first mobile terminal; therefore, the cell map is constructed based on dynamic data, and cell recommendations based on the cell map can achieve dynamic optimal cell recommendations and improve the accuracy of cell recommendations. On the other hand, the cell map includes cell entities corresponding to cell information, entity attributes corresponding to transmission quality information, and entity relationships between cell entities, and the entity relationships are used to characterize the access order of cells; therefore, the cell map can reflect the correlation and transmission quality between cells, and cell recommendations based on the small map can combine the correlation and transmission quality between cells to make cell recommendations, thereby improving the accuracy of cell recommendations. It can be seen that the embodiment of the present application can improve the accuracy of cell recommendations.

It can be seen that the embodiment of the present application can improve the accuracy of cell recommendations.

[0176] It should be noted that the cell recommendation device provided in the above embodiment only uses the division of the above functional modules as an example when making cell recommendations.
