First, a method for determining a target cell provided in an embodiment of the present application is described below.
Fig. 1 is a flowchart illustrating a target cell determination method according to an embodiment of the present application. As shown in fig. 1, the method may include the steps of:
s110, acquiring first cell information of a first cell where each subscriber identity module 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.
The first cell information comprises the standard, frequency point, base station information corresponding to the cell, cell number and the like of the cell where the SIM card resides, and the second cell information comprises the standard, frequency point, base station information corresponding to the cell, cell number and the like of the cell adjacent to the cell where the SIM card resides. The cell list includes a cell in which each SIM card resides and cells adjacent to the cell in which the SIM card resides.
After each SIM card is registered in the network, the information of the cell where the SIM card resides currently and the information of the neighboring cell configured by the network are obtained from the network side. The terminal acquires the information of the cell where the terminal currently resides and the information of the neighboring cell configured by the network, and obtains a cell list according to the cell information and the information of the neighboring cell. Each SIM card can automatically synchronize to a cell list after obtaining the information of the cell where the SIM card resides currently and the information of the neighboring cell configured by the network.
And S120, 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 is provided with antennas, each SIM card is respectively connected with a plurality of antennas, and the total number of the antennas connected with each SIM card is larger than the total number of the antennas of the terminal. For example, the terminal has N antennas in common, covers high, medium and low frequency bands, and embeds two SIM cards, card 1 and card 2, where card 1 can be connected to K1 antennas, card 2 can be connected to K2 antennas, and K1+ K2> -N.
The terminal periodically measures the signal strength value of the cell in the cell list through at least one antenna used by each SIM card. Specifically, the SIM card periodically measures the signal strength value of the neighboring cell of the cell where the SIM card resides, and then periodically measures the signal strength values of other cells in the cell list except the neighboring cell of the SIM card.
As shown in fig. 2, two SIM cards, card 1 and card 2, are built in the terminal, card 1 uses antenna 1/2/4/5 and resides in 5G cell1, its neighboring cells include 5G cell2, 4G cell3 and 4G cell4, card 2 uses antenna 1/3/4/n and resides in 4G cell5, and its neighboring cells include 4G cell4 and cell 6. The card 1 periodically measures signal strength values for 5G cell2, 4G cell3, and 4G cell4, and then periodically measures signal strength values for 4G cell5, 4G cell 6. The card 2 periodically measures signal strength values for 4G cell4 and 4G cell6, and then periodically measures signal strength values for 5G cell1, 5G cell2, and 4G cell 3.
And S130, arranging the signal intensity values according to the sequence from large to small to obtain an alternative network information table of each SIM card.

And S140, when the signal intensity value of the first cell where the SIM card resides is smaller than a preset threshold value, determining a target cell according to the alternative network information table, wherein the target cell is the cell measured by the antenna corresponding to the maximum signal intensity value in the alternative network information table.
And when the signal intensity value of the first cell where the SIM card resides is smaller than a preset threshold value, representing that the terminal communication is abnormal, and selecting the cell measured by the antenna corresponding to the maximum signal intensity value from the alternative network information table for communication. Because the alternative network information table pre-measures and sequences the signal strength value of the cell where the SIM card is located, when the terminal has communication abnormality, the alternative network can be quickly found for communication, and the reliability of communication is ensured.

In some embodiments, in order to accurately find a suitable cell for communication, the terminal associates the signal strength value with an antenna number corresponding to the signal strength value. When the terminal measures the signal strength value, the terminal associates the corresponding antenna number, for example, a certain neighboring cell of the card 1 is C11, the antenna 1 measures a cell C11, the signal strength value is R11, and if the antenna 1 measures a neighboring cell C12, the signal strength value is R11.
In some embodiments, the signal strength value is sent 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.
And sending the signal strength value of the associated antenna number to a database in real time so as to ensure that the signal strength value in the database can accurately reflect the network conditions of the cell where the SIM card resides and the current neighboring cell. The database integrates the numbers of the cells and the antennas in the cell list to obtain the signal strength value corresponding to the cell, and 1 cell can correspond to different signal strength values measured by a plurality of antennas. For example, a certain adjacent area of the card 1 is C11, the antenna 1 measures the cell C11, and the signal strength value is R11, and if the antenna 2 measures the adjacent area C11, the signal strength value is R12, that is, the card 1 may correspond to one or more of the signal strength values R11, R12, R13, R14, R15, and R1 n.
In some embodiments, the alternative network information table is updated based on the signal strength values received in real time in the database.
And the terminal maintains a latest multi-card communication information base according to the signal intensity value received in real time in the database, and arranges an alternative network information table of each SIM card from the multi-card communication information base according to the sequence of the signal intensity value from large to small according to the information of an operator, a used antenna and the like of each SIM card. Because the data in the multi-card communication information base is the latest signal intensity value, the alternative network information table is also the latest so as to ensure that when the terminal communication is abnormal, a proper cell can be selected to accurately and quickly recover the communication.
In the embodiment, the terminal makes full use of a plurality of antennas in the terminal, and cooperates with the shared network condition according to different network residence and service states of each card, so that when communication is abnormal, an alternative network can be quickly found to realize normal communication, and the reliability of multi-card terminal communication is enhanced.
