[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0030] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0031] At present, the operators' 5G / 4G / 3G / 2G networks not only have multiple standard cells with the same coverage, but also different frequency band cells of the same standard are also divided into layered structures such as base networks and capacity-added networks. After entering 5G, operators can provide different quality of service (QoS) guarantees for different users and different terminals, resulting in multiple SIM cards of the same terminal residing in multiple different cells. The existence of multiple standard multi-layer networks requires high network optimization. Mismatches and omissions in neighboring cells may cause abnormalities in the communication process, including disconnection, data disconnection, call failures, and other problems. When the terminal is disconnected from the network or communication is abnormal, if it cannot quickly find a suitable cell for normal communication, the reliability of terminal communication is reduced.

[0032] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device, equipment and computer storage medium for determining a target cell. The terminal obtains the cell information obtained by each SIM card of the terminal from the network side to obtain a cell list. By periodically measuring the signal strength values ​​of the cells in the cell list through at least one antenna used by each SIM card, the terminal's network search and measurement capabilities can be fully utilized to discover as many networks as possible at a certain time and place. According to the arrangement of the signal strength values, an alternative network information table is obtained. When the SIM card communication is abnormal, the cell measured by the antenna corresponding to the largest signal strength value in the alternative network information table is determined as the target cell. Since the signal strength values ​​in the alternative network information table are pre-arranged in ascending order, the terminal can quickly find the target cell to achieve normal communication and ensure the reliability of terminal communication.

[0033] The following first introduces the target cell determination method provided in the embodiment of the present application.

[0034] Figure 1 FIG. 1 is a flow chart of a method for determining a target cell according to an embodiment of the present application. Figure 1As shown, the method may include the following steps:

[0035] S110, obtaining first cell information of a first cell where each user identification SIM card of the terminal resides and second cell information of at least one second cell adjacent to the first cell, to obtain a cell list.

[0036] The first cell information includes the standard, frequency, base station information corresponding to the cell, cell number, etc. of the cell where the SIM card resides, and the second cell information includes the standard, frequency, base station information corresponding to the cell, cell number, etc. of the cell adjacent to the cell where the SIM card resides. The cell list includes the cell where each SIM card resides and the cells adjacent to the cell where the SIM card resides.

[0037] After each SIM card is registered to the network, it obtains the current resident cell information and the neighboring cell information configured by the network from the network side. The terminal obtains the current resident cell information and the neighboring cell information configured by the network, and obtains the cell list based on the cell information and the neighboring cell information. Each time each SIM card obtains the current resident cell information and the neighboring cell information configured by the network, it will be automatically synchronized to the cell list.

[0038] S120: Periodically measure signal strength values ​​of cells in the cell list through at least one antenna used by each SIM card.

[0039] The terminal is equipped with antennas, and each SIM card is connected to several antennas. The sum of the number of antennas connected to each SIM card is greater than the total number of antennas in the terminal. For example, the terminal has N antennas, covering high, medium and low frequency bands, and has two built-in SIM cards, namely card 1 and card 2. Card 1 can connect to K1 antennas, and card 2 can connect to K2 antennas. K1+K2>=N.

[0040] The terminal periodically measures the signal strength values ​​of the cells in the cell list through at least one antenna used by each SIM card. Specifically, the SIM card first periodically measures the signal strength values ​​of the neighboring cells of the cell where it resides, and then periodically measures the signal strength values ​​of other cells in the cell list except its neighboring cells.

[0041] like Figure 2As shown, the terminal has two built-in SIM cards, namely card 1 and card 2. Card 1 uses antenna 1 / 2 / 4 / 5 and resides in 5G cell cell1, whose neighboring cells include 5G cell2, 4G cell3 and 4G cell4. Card 2 uses antenna 1 / 3 / 4 / n and resides in 4G cell cell5, whose neighboring cells include 4G cell4 and cell6. Card 1 first periodically measures the signal strength values ​​of 5G cell2, 4G cell3 and 4G cell4, and then periodically measures the signal strength values ​​of 4G cell5 and 4G cell6. Card 2 first periodically measures the signal strength values ​​of 4G cell4 and 4G cell6, and then periodically measures the signal strength values ​​of 5G cell1, 5G cell2 and 4G cell3.

[0042] S130, arranging the signal strength values ​​in descending order to obtain a candidate network information table for each SIM card.

[0043] The terminal arranges all measured signal strength values ​​in descending order to obtain an alternative network information table for each SIM card, wherein the alternative network information table includes information such as the standard, frequency, and corresponding antenna of each cell.

[0044] S140, when the signal strength value of the first cell where the SIM card resides is less than a preset threshold, determine a target cell according to the candidate network information table, where the target cell is a cell measured by an antenna corresponding to the maximum signal strength value in the candidate network information table.

[0045] When the signal strength value of the first cell where the SIM card resides is less than the preset threshold, it indicates that the terminal communication is abnormal, and the cell measured by the antenna corresponding to the maximum signal strength value is selected from the alternative network information table for communication. Since the alternative network information table has pre-measured and sorted the signal strength values ​​of the cells where the SIM card is located, when the terminal communication is abnormal, it can quickly find an alternative network for communication, ensuring the reliability of communication.

[0046] In the embodiment of the present invention, the terminal obtains the cell information obtained by each SIM card of the terminal from the network side to obtain a cell list, and periodically measures the signal strength values ​​of the cells in the cell list through at least one antenna used by each SIM card, so that the network finding and measurement capabilities of the terminal can be fully utilized to find multiple networks at a certain time and place as much as possible, and arrange them according to the size of the signal strength values ​​to obtain an alternative network information table. When the SIM card communication is abnormal, the cell measured by the antenna corresponding to the largest signal strength value in the alternative network information table is determined as the target cell. Since the signal strength values ​​in the alternative network information table are pre-arranged in ascending order, the terminal can quickly find the target cell to achieve normal communication, thereby ensuring the reliability of terminal communication.

[0047] In some embodiments, in order to accurately find a suitable cell for communication, the terminal associates the signal strength value with the antenna number corresponding to the signal strength value. When the terminal measures the signal strength value, it associates the corresponding antenna number. For example, a neighboring cell of card 1 is C11, and the cell C11 is measured by antenna 1, and the signal strength value is R11. If antenna 1 measures the neighboring cell C12, the signal strength value is R11.

[0048] In some embodiments, after periodically measuring the signal strength values ​​of the cells in the cell list through at least one antenna used by each SIM card, the signal strength values ​​are sent to the database in real time.

[0049] The signal strength value of the associated antenna number is sent to the database in real time to ensure that the signal strength value in the database can accurately reflect the current network conditions of the cell where the SIM card resides and the neighboring cells. The database integrates the cells and antenna numbers in the cell list to obtain the signal strength values ​​corresponding to the cells. One cell can correspond to different signal strength values ​​measured by multiple antennas. For example, a neighboring cell of card 1 is C11. The signal strength value of cell C11 measured by antenna 1 is R11. If antenna 2 measures the neighboring cell C11, the signal strength value is R12. In other words, card 1 can correspond to one or more of the signal strength values ​​R11, R12, R13, R14, R15, and R1n.

[0050] In some embodiments, the candidate network information table is updated according to the signal strength value received in real time in the database.

[0051] The terminal maintains an up-to-date multi-card communication information database based on the signal strength values ​​received in real time in the database, and arranges the alternative network information table of each SIM card in the multi-card communication information database in descending order of signal strength values ​​according to the operator of each SIM card, the antenna used, and other information. Since the data in the multi-card communication information database is the latest signal strength value, the alternative network information table is also the latest, to ensure that when the terminal communication is abnormal, it can select the appropriate cell and restore communication accurately and quickly.

[0052] In this embodiment, the terminal makes full use of its internal multiple antennas to collaboratively share network conditions according to the different network and service status of each card. When communication anomalies occur, an alternative network can be quickly found to achieve normal communication, thereby enhancing the reliability of multi-card terminal communication.

[0057] The determination module 340 is used to determine a target cell according to the candidate network information table when the signal strength value of the first cell where the SIM card resides is less than a preset threshold, wherein the target cell is the cell measured by the antenna corresponding to the maximum signal strength value in the candidate network information table.

[0058] In some embodiments, the apparatus further comprises an associating module 350 for associating the signal strength value with an antenna number corresponding to the signal strength value.

[0059] In some embodiments, the apparatus further includes a sending module 360, which is configured to send the signal strength values ​​to the database in real time after periodically measuring the signal strength values ​​of the cells in the cell list through at least one antenna used by each SIM card.

[0060] In some embodiments, the apparatus further includes an updating module 370 for updating the candidate network information table according to the signal strength value received in real time in the database.

[0061] In this embodiment, the terminal makes full use of its internal multiple antennas to collaboratively share network conditions according to the different network and service status of each card. When communication anomalies occur, an alternative network can be quickly found to achieve normal communication, thereby enhancing the reliability of multi-card terminal communication.
