Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a cell selection method according to an exemplary embodiment, which is applied to a terminal including a plurality of subscriber identity cards, and the method includes:

step S101, responding to a terminal to switch a user identification card for data communication, and reading cell configuration information prestored by the terminal; the cell configuration information is determined according to historical residence information of a plurality of user identification cards;

and step S102, determining the cell where the switched user identification card resides according to the cell configuration information.

In the embodiment of the present disclosure, the terminal may determine the cell configuration information according to the historical residence information of the multiple subscriber identity cards, that is, the cell configuration information pre-stored in the terminal includes parameters related to the historical residence information of each of the multiple subscriber identity cards.

In the process of switching the subscriber identity module card, the terminal needs to select a cell for the switched subscriber identity module card and resides in a new cell.

In an embodiment, the cell search is a process in which a UE (User Equipment), i.e., the terminal, acquires time and frequency synchronization with a cell and detects a cell ID. The cell selection process of the terminal comprises the following steps: both the information cell selection and the initial cell selection are stored.

The stored information cell selection procedure requires stored information about the carrier frequency and cell parameters. Relevant cell information is retrieved from previous measurement control information or from pre-existing system messages, which may help speed up the cell selection process. The stored information unit selection process is as follows:

firstly, a terminal searches a suitable cell in a known carrier frequency;

secondly, if the terminal finds a suitable cell, the terminal selects a cell to camp on;

thirdly, if the terminal fails to find a suitable cell, an initial cell selection procedure is initiated.

The initial cell selection process does not require the terminal to pre-direct which frequencies are available, e.g., the terminal will scan all carrier frequencies on the 5G band for a suitable cell. The terminal searches only for the strongest cell on each carrier frequency and if the terminal finds a suitable cell, it selects the cell on which to camp. If the terminal fails to find a suitable cell, a cell to camp on is selected.

For a terminal with a plurality of subscriber identity modules, when the terminal switches the subscriber identity modules, cell selection is required for the switched subscriber identity modules. For example, when only a single-card SA (stand alone) is supported in a dual-card mobile phone in the same carrier network, only the data master card may reside in the SA network, and if the subscriber identity card is switched, the data master card is switched. At this time, no matter what network the switched subscriber identity card originally is in or is not connected to the network, the SA network-residing flow needs to be started. The switched subscriber identity module card firstly performs a cell selection process of stored information, and in the process, the subscriber identity module card searches and compares cell information of frequency points, including cell information such as frequency point information and cell ID, RSRP (Reference Signal Received Power), SNR (Signal-to-Noise Ratio), and other information, which are pre-stored correspondingly to the subscriber identity module card, and selects an SA cell with the best quality. In this case, it is assumed that the SA cell at a certain frequency meets the camping condition, but the camping condition is very low, so that the subscriber identity card after the handover camps in the SA cell with a poor signal.

Therefore, in the embodiment of the present disclosure, the terminal prestores the historical residence information based on the multiple subscriber identity cards, and when the subscriber identity cards are switched, the terminal does not perform cell search based on the historical residence information of the switched subscriber identity cards, but selects the residence cell based on the historical residence information of the multiple subscriber identity cards, so that the residence cell with better signal quality can be selected from the residence cells based on the historical residence of the multiple subscriber identity cards, and therefore, the situation that the switched subscriber identity cards reside in the cells with poorer signal quality due to incomplete information can be avoided, and the signal degradation after the subscriber identity cards are switched can be reduced.

In some embodiments, as shown in fig. 2, the method further comprises:

step S201, determining a preset signal quality condition;

step S202, determining the cell configuration information according to the preset signal quality condition and the historical residence information of the plurality of user identification cards.

In the embodiments of the present disclosure, the terminal may determine the cell configuration information based on a preset signal quality condition. The preset signal quality condition may include information such as a restriction condition on frequency point information, RSRP, SNR, and the like of the cell. The historical camping information may include cell parameters acquired when each user identification card in the terminal historically camps on each cell, including frequency point information, RSRP, SNR, and other information. For example, the preset signal quality condition may include a minimum threshold for signal strength, a minimum threshold for signal-to-noise ratio, and the like. The terminal may determine whether a cell parameter corresponding to a cell where the user identifier card is historically resident satisfies the preset signal quality condition based on the historical residence information of the user identifier cards, and if so, may store the relevant information of the corresponding cell in the cell configuration information, and if not, may not store the relevant information in the cell configuration information. It is to be understood that the preset signal quality condition may include a threshold or a value range of a plurality of parameters, and it may be specified that the preset signal quality condition is satisfied when the cell parameter satisfies which or those parameters correspond to.

Therefore, when the subscriber identity module card is switched, the terminal can select the resident cell based on the cell configuration information screened by the preset signal quality condition, so that the condition that the resident cell does not meet the preset signal quality condition is reduced, and the resident cells of the subscriber identity module card after switching and the subscriber identity module card before switching can meet the preset signal quality condition as much as possible.

In the using process of the terminal, it may be experienced that each subscriber identity card resides in different cells at different stages, and therefore, corresponding configuration information may be determined respectively for the historical residence information of each subscriber identity card. The configuration information may be parameter information required when the subscriber identity module card resides in a corresponding cell, for example, the configuration information may include cell parameters or parameter sets of a history resident cell, including information such as frequency point information, RSRP, SNR, and the like; cell identification, channel information, power information and the like required when the historical resident cell is resident can be further included; for example, for a dual card handset, the configuration information corresponding to each card is stored based on card 1 and card 2. The configuration information may store all or corresponding historical residence information of each subscriber identity card within a preset time period.

And then screening the configuration information corresponding to the plurality of user identification cards based on a preset signal quality condition, and selecting the configuration information meeting the preset signal quality condition to form the cell configuration information. Therefore, the cell configuration information includes configuration information corresponding to a cell satisfying a preset signal quality condition among cells where the plurality of subscriber identity cards are resided in history, that is, parameter information required by the terminal when the plurality of cells where the plurality of subscriber identity cards are resided in history use reside.

Therefore, when the user identification card is switched by the terminal, the terminal can select the cell in a larger range according to the cell configuration information compared with the domestic configuration information according to the switched user identification card, the signal quality of the selectable cell is better, the cell selection efficiency is improved, and the terminal can be conveniently and quickly resided in the cell with better signal quality.

In the embodiment of the present disclosure, the terminal may update the cell configuration information when any subscriber identity card resides in the cell. When any subscriber identity module card resides in a cell, the terminal can firstly judge whether the current cell meets the preset signal quality condition, and if so, the cell configuration information can be updated according to the cell information of the current cell; if not, the signal quality of the current cell is poor, so that the cell information of the current cell can be ignored and not stored, and the possibility that the current subscriber identity module card or other subscriber identity modules reside in the cell with poor signal quality in the subsequent use process is reduced.

searching at least one cell in the current coverage range;

The terminal can search the cell within the range of the terminal in the process of switching the user identification card. After at least one cell is searched, matching can be performed based on cell configuration information pre-stored by the terminal, and if a matched cell exists, the terminal is indicated to have resided in the cell, so that the cell can be resided quickly, and signaling interaction required for residence is reduced.

In some embodiments, the method further comprises:

Since there may be various possibilities of movement for the terminal, there may be no cell matching the currently stored cell configuration information among the searched cells. At this time, a cell satisfying a preset signal quality condition, for example, a signal strength greater than a threshold value defined by the preset signal quality condition, may be searched from the searched cells and camped in the cell.

In addition, if there is no cell satisfying the predetermined signal quality condition, a cell with the best signal quality, for example, the lowest signal-to-noise ratio, the highest signal strength, or the highest reference signal received power, may be selected from the searched cells and camped in the cell.

Of course, if the terminal searches for only one cell, it may directly camp on the cell.

The disclosed embodiments also provide the following examples:

as shown in fig. 3, the cell search and cell selection process of the SA is firstly PLMN (Public Land Mobile Network) selection, and after a suitable PLMN is selected, cell selection is started, and the cell selection process is firstly performed information storage cell selection process, which is to perform frequency scanning to obtain an SA cell according to the previously stored frequency point list information of the UE, so that the cell selection process can be accelerated. The initial cell selection process is that the UE does not know any frequency point information, the UE scans all frequency points in each frequency band to search the strongest SA cell after the UE searches the SA cell according to the frequency band index issued to the physical layer by the upper layer, if a proper SA cell is found, the SA cell normally resides, otherwise, the acceptable SA cell to reside is selected, and under the condition, the UE enters the limited service state.

On the premise that only a single-card SA network is supported in a dual-card mobile phone under the same operator network, only a data main card can be resident in the SA network. When the data master card is switched to operate, no matter what network the new data master card (hereinafter, referred to as the new master card) is in before, the new master card will start the SA network-residing flow. The new master card will first perform a cell selection process for storing information, in which the frequency point cell information stored before the card is searched and compared, including information such as frequency point information, cell information, RSRP (Reference Signal Received Power), and SNR (Signal-to-noise ratio). And selecting the SA cell with the optimal quality. In this case, there may be an SA cell at a certain frequency point satisfying the camping condition (the camping condition is low), and although the SA cell has a poor signal, the new master card may camp on the SA cell with the poor signal. This causes the SA cell where the new master card resides in the same operator network to have much worse signal than the SA cell where the original data master card (hereinafter referred to as the old master card) resides in.

Aiming at the situation that the SA cell signal where a new main card resides is different from the SA cell where an old main card resides when double cards (such as double telecom cards) switch data main cards under the same operator network under the SA network are operated, the user experience is greatly influenced, and therefore the situation that the double cards share 5G frequency point cell information under the same operator when the data main cards are switched under the SA network is provided. A cell selection threshold is set, frequency point cells higher than the threshold in dual-card storage frequency point cell information are screened out, SA cells are selected from the screened frequency point cell information, and therefore another card can select the SA cells with the best quality from the shared frequency point cell information in the process of residing in the SA cells at any time.

As shown in fig. 4, the cell selection method provided by the embodiment of the present disclosure includes that a user identification card includes a card 1 and a card 2, and cell information including frequency points, cell IDs, RSRPs, SNRs, and other information, which are historically resident in a memory card 1, may be written into a configuration file 1; for the card 2, the cell information where the card 2 resides in history is stored and written into the configuration file 2. In some embodiments, the configuration files 1 and 2 are independent from each other and cannot be shared, for example, after the data master card is switched from the card 1 to the card 2, the card 2 will perform cell selection, but the card 2 will only search for a suitable cell in the configuration file 2 to camp on, and will not read the configuration file of the card 1.

In the embodiment of the present disclosure, the configuration file 3 is set by a preset signal quality condition, for example, a threshold of a parameter such as RSRP or SNR is set on an upper layer of a mobile phone terminal as the preset signal quality condition. The configuration file 3 includes configuration files stored for the card 1 and the card 2, respectively, including a frequency point cell information list and the like. And, the cells stored in the profile 3 satisfy the above-mentioned preset signal quality condition. Therefore, the SA cells with better signal quality can be screened out, and the SA cells with poorer signal quality are removed, so that the time length for selecting the cells to search and compare when the subscriber identity card is switched is shortened.

In the embodiment of the present disclosure, the terminal may perform the above operation when receiving a switching instruction for switching the User identification card through a User Interface (UI).

In the embodiment of the present disclosure, when the switched subscriber identity module card performs cell selection, the configuration information such as the frequency point cell in the configuration file 3 may be directly read, so as to search and compare the information, find the SA cell with the best quality, and then reside in the SA cell.

By the method in the embodiment of the disclosure, in the process of switching the data master card, i.e. the subscriber identity module card, the SA cell where the switched subscriber identity module card resides can be the SA cell with better signal quality, even the SA cell with the best signal quality in the current available cells. Moreover, the method is convenient for fast network residence, signaling overhead is saved, power consumption is saved, and the condition of signal quality reduction caused by switching the user identification card is reduced, thereby improving user experience.
