[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] In order to more clearly explain the cell search method provided in the embodiment of the present application, the scenario in which the method is applied is explained below.

[0041] Figure 1 This is a schematic diagram of the application scenario provided in the embodiment of this application, please refer to Figure 1In this scenario, a terminal device 110 and a server 120 may be included, wherein the terminal device 110 may be in a high-speed moving state, for example, it may be on a highway, or a high-speed rail, subway, etc., and no specific limitation is made here.

[0042] In one embodiment, the terminal device 110 may include but is not limited to a mobile phone, a wearable device (such as a smart watch, a smart bracelet, smart glasses, etc.), a tablet computer, a laptop computer, a vehicle terminal (such as a vehicle computer), a PC (Personal Computer), etc. The function implemented by the method can be implemented by calling a program code by a processor in the terminal device, and of course the program code can be stored in a computer storage medium. It can be seen that the terminal device at least includes a processor and a storage medium.

[0043] In one embodiment, the server 120 may be a server set up in the cloud, and a large amount of cell-related data may be stored in the server, such as the location of each cell, cell information of each cell, etc., which is not specifically limited here.

[0044] A base station may be set up in each cell, and the terminal device 110 may establish a communication connection with the server 120 through the base station. When the terminal device is moving at high speed, it may change the cell, for example: Figure 1 The cell 1 shown in FIG. 1 enters the cell 2. In this case, the terminal device 110 can switch from being connected to the server 120 through the base station of cell 1 to being connected to the server 120 through the base station of cell 2.

[0045] In one embodiment, the scenario may include multiple cells, and a base station of one of the cells may be selected according to the actual location of the terminal device 110 to implement communication between the terminal device 110 and the server 120 .

[0046] In the related art, before switching a cell, a terminal device usually needs to search for other cells adjacent to the cell to achieve cell switching. However, when the terminal device is in a high-speed moving state, due to the Doppler effect, the terminal device will search for the network slowly, which will further make the terminal device's network poor and the user's experience of surfing the Internet using the terminal device poor.

[0047] The Doppler effect refers to the fact that the received frequency of a wave becomes higher when the wave source moves toward the observer, and becomes lower when the wave source moves away from the observer. The same conclusion can be drawn when the observer moves. The wave can be a signal sent by a terminal device, the wave source can be the terminal device, and the observer can be any base station. Due to the Doppler effect, the frequency received by the base station may change, causing the terminal device to have a poor network. In this case, the user's experience of using the terminal device to access the Internet is poor.

[0048] In order to solve the above problems existing in the related art, a cell search method is provided in an embodiment of the present application, and the actual implementation process of the cell search method is explained below.

[0049] Figure 2 Please refer to the flowchart of the cell search method applied to the terminal device provided in the embodiment of the present application. Figure 2 , a cell search method, applied to a terminal device, the method comprising:

[0050] S210: When the moving speed of the terminal device is greater than or equal to a preset speed threshold, the moving information of the terminal device is sent to the server.

[0051] It should be noted that the execution subject of this method may be the above-mentioned terminal device.

[0052] The moving speed of the terminal device refers to the moving speed of the terminal device itself when it is in a moving state, and the moving speed can be obtained in many ways.

[0053] For example, the acceleration of the terminal device can be obtained from the terminal device's gyroscope, the current position of the terminal device can be determined based on the terminal device's Global Positioning System (GPS), and then the speed of the terminal device can be calculated based on the position change of the terminal device over a period of time and the acceleration during that period of time.

[0054] For another example, the moving speed of the terminal device can be estimated based on the distance between each cell and the frequency of the terminal device switching cells.

[0055] It should be noted that, in actual application, any one of the above two methods can be used to realize the acquisition of the moving speed of the terminal device, or, if the terminal device has other functions, for example: it is equipped with a speed acquisition device, etc., other methods can also be used to obtain the moving speed of the terminal device, and no specific restrictions are made here.

[0056] After the moving speed of the terminal device is obtained, the relationship between the moving speed of the terminal device and a preset speed threshold may be compared.

[0057] Among them, if the moving speed of the terminal device is greater than or equal to the preset speed threshold, it is determined that the terminal device meets the conditions for cell search and the cell search can be performed; conversely, if the moving speed of the terminal device is less than the preset speed threshold, it is determined that the terminal device does not meet the conditions for cell search and the cell search cannot be performed.

[0058] In one embodiment, when the moving speed of the terminal device is greater than or equal to a preset speed threshold, the moving information of the terminal device may be sent to the server, wherein the moving information includes: the current location of the terminal device and the moving path of the terminal device.

[0059] It should be noted that the current location of the terminal device may be obtained through the above-mentioned GPS system, and the moving path of the terminal device may be obtained through navigation software, for example: it may be input by the user or preset, and no specific limitation is made here.

[0060] After the terminal device sends the movement information to the server, the server may determine a plurality of target cells according to the movement information, and may send the cell information of these target cells to the terminal device.

[0061] S220: Receive cell information of multiple target cells sent by the server.

[0062] It should be noted that, when the terminal device can be connected to the Internet normally, the cell information of multiple target cells sent by the server can be received.

[0063] The cell information of the target cell is determined by the server according to the mobile information. The target cell is a cell in the mobile path of the terminal device. The server stores the cell information of multiple cells, including the cell in the mobile path.

[0064] It should be noted that the target cell can be all the cells in the mobile path of the terminal device, or it can be part of the cells. There is no specific restriction here. For example, if there are 20 cells on the mobile path of the terminal device, all of these 20 cells can be used as target cells, or 10 of them can be used as target cells. After each connection is established with one of the cells, the data is updated once and a target cell is added. There is no specific restriction here.

[0065] The cell information of the target cell may include identification information and frequency band information of the cell, wherein the identification information may represent the ID (Identity document) of the cell. The ID of each cell may be independent, and the identification information of different cells may be different.

[0066] The frequency band information can identify the frequency band used when establishing a connection with the cell. During the network search process, the network search can be performed according to the frequency band. The frequency band information can be the frequency band used when other devices establish a connection with the base station of the cell. The server can save this information.

[0067] S230: Perform cell search according to the cell information of the target cell.

[0068] It should be noted that after obtaining the cell information of the target cell, a cell search can be performed. For example, the cell that needs to be searched can be determined based on the cell identification information, and then the network can be searched based on the cell's frequency band information, so that the terminal device can search for the base station of the corresponding target cell, thereby preparing for the subsequent establishment of a communication connection.

[0069] In the cell search method provided in the embodiment of the present application, when the moving speed of the terminal device is greater than or equal to the preset speed threshold, the moving information of the terminal device is sent to the server; the cell information of multiple target cells sent by the server is received, the cell information of the target cell is determined by the server according to the moving information, the target cell is a cell in the moving path of the terminal device, the server stores the cell information of multiple cells, and the multiple cells include the cell in the moving path; the cell search is performed according to the cell information of the target cell. Among them, by obtaining the cell information of the target cell in advance, the cell search can be performed in advance according to the cell information of these target cells, thereby shortening the network search time of the terminal device, and improving the network experience of the terminal device when the terminal device is in a high-speed moving state.

[0070] In one embodiment, the cell information includes: identification information and frequency band information.

[0071] It should be noted that the identification information may include: a PCI (Physical Cell Identity) identification of the cell itself and a PLMN (Public Land Mobile Network) identification of the cell in the cell network.

[0072] The frequency band information may include: BAND information and Frequency information, wherein the BAND information refers to the frequency band or frequency band used in the communication field, which refers to the wavelength range between the specified minimum wavelength and the maximum wavelength, or the specific frequency range used in radio communication; the Frequency information may be one or more specific frequencies.

[0073] It should be noted that these data can be stored in the server, and a corresponding physical address can be stored for each cell. After the terminal device sends the mobile information to the server, the server can determine the corresponding physical address based on the mobile information, and then find multiple cells that meet the location, use these cells as target cells, and send the cell information of the target cell to the terminal device.

[0074] In one embodiment, performing a cell search based on the cell information of the target cell includes: establishing a priority network search list based on the cell information, the priority network search list including identification information of multiple target cells arranged in target order; and performing a cell search based on the priority network search list.

[0075] It should be noted that after the terminal device obtains the cell information, it can establish a priority network search list based on the cell information.

[0076] The priority network search list may be a list used by the terminal device when searching for a network, and base stations of cells recorded in the priority network search list may be preferentially searched according to the priority network search list.

[0077] The following is an explanation of one implementation process of performing a cell search based on a priority search list in an embodiment of the present application.

[0078] Figure 3 For a schematic diagram of a priority search list provided in an embodiment of the present application, please refer to Figure 3 , Figure 3 The priority network search list in the target search includes identification information of multiple target cells arranged in target order.

[0079] In one embodiment, the network search may be performed in the order of the identification information. For example, the network search may be performed on the cell of identification information 1 first, and then on the cell of identification information 2, until all the cells corresponding to the identification information are searched.

[0080] It should be noted that, during the network search process, the frequency band information corresponding to the identification information may be used to search and find the corresponding target cell.

[0081] Figure 3 The network search process shown in is an optional implementation process of searching according to the priority network search list. In actual applications, other network search methods can also be used.

[0082] In the cell search method provided in the embodiment of the present application, a priority search list can be established according to the cell information, and the priority search list includes identification information of multiple target cells arranged in a target order; the cell search is performed according to the priority search list. Among them, by searching the network in advance in order according to the priority search list, the network search time of the terminal device can be shortened, and the network experience of the terminal device can be improved when the terminal device is in a high-speed moving state.

[0083] In one embodiment, performing a cell search based on the cell information of the target cell includes: storing the identification information and frequency band information of the target cell in the historical connection record of the terminal device; and performing a cell search based on the frequency band information in the historical connection record during the search for the target cell.

[0084] It should be noted that after the terminal device obtains the cell information, the cell information can be stored in the historical connection record of the terminal device.

[0085] Among them, the historical connection record can be a record of the terminal device connecting to the base station of any cell. It can be recorded according to the base station of the cell to which the terminal device has been connected. The content of the record may include the identification information and frequency band information of the cell.

[0086] The historical connection record of the terminal device can be increased by actively adding, for example: the identification information and frequency band information of multiple target cells can be added to the historical connection record of the terminal device. During the network search process, the terminal device can search the network according to the historical connection record.

[0087] The following is an explanation of one implementation process of performing a cell search based on historical connection records in an embodiment of the present application.

[0088] Figure 4 For a schematic diagram of the historical connection record provided in the embodiment of the present application, please refer to Figure 4 , Figure 4 The historical connection records in the storage include identification information and frequency band information of multiple cells.

[0089] In one embodiment, during the network search process, the terminal device can search the network based on historical connection records. For example, if it is necessary to search the network of cell 1, it can search based on frequency band 1 to find cell 1; if it is necessary to search the network of cell 2, it can search based on frequency band 2 to find cell 2.

[0090] It should be noted that the frequency band information can be stored in the server, and the frequency band information in the server can be sent by other terminal devices. For example, device A can upload its historical connection records to the server, and the server can record and store the frequency band information of the connection between device A and the base station of a certain cell. If the frequency band information is sent to device B through the server, device B can establish a connection with the same base station based on the frequency band information according to the same frequency band information.

[0091] Figure 4 The network search process shown in is an optional implementation process of searching according to historical connection records. Other network search methods can also be used in actual applications.

[0092] In the cell search method provided in the embodiment of the present application, the identification information and frequency band information of the target cell can be stored in the historical connection record of the terminal device; in the process of searching for the target cell, the cell search is performed based on the frequency band information in the historical connection record. Among them, the frequency band information of the base station of each cell can be determined more accurately through the historical connection record, so that the network can be searched more quickly, the network search time of the terminal device can be shortened, and the network experience of the terminal device can be improved when the terminal device is in a high-speed moving state.

[0093] In one embodiment, before performing a cell search, it may be determined whether the terminal device meets corresponding conditions.

[0094] Figure 5 For a flow chart of determining whether to perform a cell search according to the state of a terminal device provided in an embodiment of the present application, please refer to Figure 5 Before sending the mobile information of the terminal device to the server, the method further includes:

[0095] S510: Determine whether the terminal device is in a navigation state.

[0096] Wherein, when the navigation application of the terminal device is in a running state, it is determined that the terminal device is in a navigation state.

[0097] For example, when the terminal device is a mobile terminal such as a mobile phone, the navigation state can be entered by opening the map navigation software. For example, if navigation software A is configured in the terminal device, navigation software A can be started. When the navigation software is running in the foreground or background, it can be determined that the terminal device is in the navigation state.

[0098] For example, when the terminal device is a vehicle-mounted terminal such as a car computer, the navigation state can be entered by executing a navigation function, for example, the navigation state can be entered by starting the vehicle to automatically turn on the navigation mode.

[0099] Accordingly, the mobile information of the terminal device is sent to the server, including:

[0100] When the terminal device is in the navigation state, S520: determine the moving path of the terminal device, and send the moving path of the terminal device to the server.

[0101] It should be noted that if the terminal device is not in the navigation state, it can be determined that navigation is not required, that is, cell search is not required; if the terminal device is in the navigation state, it can be determined that navigation is required, and the moving path of the terminal device can be determined and sent to the server.

[0102] In addition, the current location of the terminal device can also be determined and sent to the server, thereby sending the movement information of the terminal device to the server.

[0103] In the cell search method provided in the embodiment of the present application, it is possible to determine whether the terminal device is in a navigation state; when the terminal device is in a navigation state, the moving path of the terminal device is determined, and the moving path of the terminal device is sent to the server. By determining whether the terminal device is in a navigation state, it is possible to more quickly determine whether the terminal device has a navigation requirement, and then when there is a navigation requirement, the moving path of the terminal device can be uploaded more quickly, further improving the speed of cell search.

[0104] It should be noted that in the process of determining the moving path of the terminal device, multiple methods may be used to implement it.

[0105] In one embodiment, determining the moving path of the terminal device includes: generating at least one moving path to be selected in response to a selection operation for a target location; and determining the moving path of the terminal device from the at least one moving path to be selected.

[0106] Figure 6 For a schematic diagram of the movement path selection provided in the embodiment of the present application, please refer to Figure 6 , Figure 6 What is displayed in the figure may be an interface diagram of a terminal device, for example, a map in a navigation software, where the user can manually input the starting point and the end point, and the navigation software calculates multiple optional routes based on the road conditions, that is, Figure 6 Path 1, Path 2 and Path 3 in .

[0107] In one embodiment, the starting point may be determined according to the current position of the terminal device, the end point may be a target position selected by the user, and the selected moving path may be generated after calculation by the terminal device.

[0108] In the actual implementation process, the user can select one of the multiple candidate moving paths as the moving path of the terminal device. For example, Figure 6 Select one of the paths 1, 2, and 3.

[0109] In the cell search method provided in the embodiment of the present application, at least one candidate moving path can be generated in response to a selection operation for a target location; and a moving path of a terminal device is determined from the at least one candidate moving path. The moving path can be determined more quickly and accurately by user selection, thereby improving the speed at which the terminal device determines the moving path.

[0110] In the process of determining the moving path of the terminal device, other methods may also be used to implement it.

[0111] In one embodiment, determining the moving path of the terminal device includes: determining the moving path of the terminal device according to the current position of the terminal device, the current time, and a path generation model.

[0112] It should be noted that the path generation model can be a pre-trained AI big data model, and the path generation model can be obtained after training based on the historical travel locations, historical travel times, and historical travel paths of the terminal device.

[0113] For example: if a user often uses a terminal device to travel at time A and location B, and the movement path corresponding to the travel is movement path C, then when the user travels again at a similar time and / or similar location, a similar movement path C can be automatically generated.

[0114] The structure of the path generation model is as follows:

[0115] Figure 7 This is a schematic diagram of the structure of the path generation model provided in the embodiment of the present application. Please refer to Figure 7 ,The input of the model can be the current location and the current time of the terminal ,device, and the output can be the moving path.

[0116] Among them, the current position can be obtained according to the GPS system of the terminal device, and the current time can be obtained through the time system of the terminal device. In the actual application process, the moving path can be determined based on the current position and the current time, or the moving path can be determined based on one of the information of the current position or the current time. There is no specific limitation here.

[0117] It should be noted that Figure 7The structure shown is only one example. In actual applications, the path generation model can also be used to determine the movement path based on other relevant information, for example: based on the user's usage habits, based on the user's identity, based on the current road congestion, etc., without specific limitations here.

[0118] In the cell search method provided in the embodiment of the present application, the moving path of the terminal device can be determined according to the current position of the terminal device, the current time and the path generation model. Among them, the path generation model can reduce the user's operation and more quickly determine the moving path of the terminal device, thereby improving the efficiency of obtaining the moving path.

[0119] In the process of determining the moving path of the terminal device, other methods may also be used to implement it.

[0120] In one embodiment, determining the movement path of the terminal device includes: determining vehicle information of the vehicle taken by the user based on the travel information in the terminal device, the vehicle information including: the vehicle's driving route; determining the movement path of the terminal device based on the vehicle's driving route and the current location of the terminal device.

[0121] It should be noted that the travel information may be the user's travel itinerary stored in the terminal device. For example, after the user purchases a vehicle ticket through ticket purchase and payment, the received payment information may be used as one type of travel information.

[0122] For example: after a user purchases a train ticket, the train ticket itinerary received through the terminal device can be used as itinerary information; when a user pays for a bus or subway by scanning a code through the terminal device, the payment information can also be used as itinerary information.

[0123] It should be noted that the vehicle information of the vehicle taken by the user can be determined based on the travel information of the terminal device, for example: the license plate number, train number, etc. can be obtained, and then the vehicle's driving route can be obtained through network query, and the vehicle's driving route can be used as vehicle information.

[0124] After the vehicle information is determined, the moving path of the terminal device can be determined based on the current location of the vehicle and the driving route of the vehicle.

[0125] For example, the vehicle's driving route may include multiple stations. The current location of the terminal device or the station closest to the driving route can be used as the starting point, the destination of the driving route or the station selected by the user can be used as the end point, and the route connecting all the stations between the starting point and the end point in the driving route can be used as the moving path of the terminal device.

[0126] Figure 8This is a schematic diagram of determining a moving path based on vehicle information provided in an embodiment of the present application. Please refer to Figure 8 The travel information of the terminal device can be obtained through text messages and other means. For example, if the text message shows that you took "vehicle A" at X:X on X:X on X:X, you can query the relevant information of vehicle A. For example, if vehicle A is a bus, you can query the bus route; if vehicle A is a subway or a train, you can query the subway or train route to obtain the vehicle information.

[0127] After the vehicle information is determined, the moving path of the terminal device may be determined based on the current location of the terminal device and the driving route of the vehicle.

[0128] In the cell search method provided in the embodiment of the present application, the vehicle information of the vehicle taken by the user can be determined based on the itinerary information in the terminal device, and the vehicle information includes: the driving route of the vehicle; the moving path of the terminal device is determined based on the driving route of the vehicle and the current position of the terminal device. Among them, by obtaining the itinerary information, the driving route of the vehicle can be determined more quickly and accurately, and then the moving path of the terminal device can be calculated more accurately, thereby improving the efficiency of determining the moving path.

[0129] It should be noted that the above processes are all solutions executed by the terminal device side. In the actual implementation process, the server can also perform corresponding steps when executing the cell search method. The specific implementation method is as follows:

[0130] Fig. 9 Please refer to the flowchart of the cell search method applied to the server provided in the embodiment of the present application. Fig. 9 , a cell search method, applied to a server, the method comprising:

[0132] It should be noted that the execution subject of the method may be the above-mentioned server, and the server may receive the mobile information sent by the terminal device.

[0133] The movement information includes: the current location of the terminal device and the movement path of the terminal device.

[0134] In one embodiment, the server stores cell information of multiple cells, and the cell information of these cells may be uploaded to the server by other terminal devices, for example, may be uploaded by other devices using the same communication operator as the terminal device.

[0135] S920: According to the current position of the terminal device and the moving path of the terminal device, cell information of multiple target cells is determined from the cell information of multiple cells and sent to the terminal device.

[0136] It should be noted that after the terminal device obtains the mobility information, it can determine the cell information of the target cell from the multiple cell information according to the mobility information.

[0137] The target cell is a cell in the moving path of the terminal device, and the terminal device is used to perform a cell search based on the cell information of the target cell.

[0138] In one embodiment, cell information of multiple target cells is determined from cell information of multiple cells based on the current location of the terminal device and the moving path of the terminal device, including: determining a location interval of a cell to be selected based on the current location of the terminal device and the moving path of the terminal device; determining multiple target cells from the location interval of the cell to be selected, and determining cell information of multiple target cells from the cell information of the multiple cells.

[0139] Optionally, the geographical location that the terminal device will pass through along the moving path can be determined based on the current location of the terminal device and the moving path of the terminal device, thereby obtaining a candidate cell location interval, which can be an actual geographical location range, for example: it can be expressed by longitude and latitude.

[0140] The cells in the candidate cell location interval can be used as target cells. For example, if the candidate cell location interval involves 20 cells, these 20 cells can all be used as target cells, and then the cell information of these target cells can be obtained from the preset database, and the cell information can be sent to the terminal device.

[0141] Among them, the preset database can be a pre-built cloud base station database, or it can be a cloud base station cell information database built by terminal manufacturers and operators for various highway lines, subway lines, bus lines, and train lines. The data source in the database can be uploaded by any terminal device.

[0142] In the cell search method provided in the embodiment of the present application, mobile information sent by a terminal device can be received; according to the current location of the terminal device and the moving path of the terminal device, cell information of multiple target cells can be determined from the cell information of multiple cells and sent to the terminal device. Among them, by obtaining the cell information of the target cell in advance, the cell search can be performed in advance according to the cell information of these target cells, thereby shortening the network search time of the terminal device and improving the network experience of the terminal device when the terminal device is in a high-speed moving state.

[0150] It should be noted that step S1010 and step S1020 may be used to determine whether the terminal device meets the cell search conditions. If so, the solution may continue to be executed. Otherwise, the solution may end.

[0151] After executing step S1050, the determination of step S1020 may be further looped until the terminal device exits the navigation state.
