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, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

Fig. 1 is a flow chart of a cell selection method according to an exemplary embodiment, the method is applied to a terminal including multiple subscriber identification cards, as shown in Fig. 1, the method includes:

Step S101, in response to the terminal switching the subscriber identity card used for data communication, read the cell configuration information pre-stored by the terminal; wherein the cell configuration information is determined according to the historical resident information of multiple subscriber identity cards;

Step S102, according to the cell configuration information, determine the cell where the switched subscriber identity card resides.

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

During the process of switching the subscriber identity card, the terminal needs to perform cell selection for the switched subscriber identity card and camp in the new cell.

In an embodiment, the cell search is a process in which a UE (User Equipment, user equipment), that is, the above-mentioned terminal, synchronizes time and frequency with a cell and detects a cell ID. The cell selection process of the terminal includes: storage information cell selection and initial cell selection.

Stored Information The cell selection process requires stored information related to carrier frequency and cell parameters. The relevant cell information is retrieved from previous measurement control information or from pre-existing system messages, which can help to speed up the cell selection process. The storage information unit selection process is as follows:

First, the terminal searches for a suitable cell in a known carrier frequency;

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

Third, if the terminal fails to find a suitable cell, it initiates an initial cell selection process.

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

For a terminal with multiple subscriber identity cards, when switching subscriber identity cards, the terminal needs to perform cell selection for the switched subscriber identity cards. For example, when dual-card mobile phones under the same operator network only support single-card SA (Standalone, independent networking), only the main data card can reside in the SA network. If the user identification card is switched, the data main card will be switched. Card. At this time, no matter what network the switched subscriber identity card is in or not connected to the network, it is necessary to start the SA network residency process. After switching, the subscriber identity card will firstly carry out the cell selection process of stored information. During this process, it will search and compare the pre-stored frequency cell information corresponding to the subscriber identity card, including frequency point information, cell ID and other cell information, RSRP (Reference Signal Received Power , refer to information such as signal received power) and SNR (Signal-to-NoiseRatio, signal-to-noise ratio), and select the SA cell with the best quality. In this case, there is an SA cell under a certain frequency that satisfies the camping condition, but the camping condition is very low, so that the switched subscriber identity card camps on the SA cell with poor signal.

Therefore, in the embodiment of the present disclosure, the terminal pre-stores historical residence information based on multiple subscriber identity cards, and when the terminal switches subscriber identity cards, it does not perform cell search based on the historical residence information of the switched subscriber identity cards. Instead, the cell to camp on is selected based on the historical residency information of multiple subscriber identity cards. In this way, the cell with better signal quality can be selected to reside in the cell based on the historical residency information of multiple subscriber identity cards. Incompleteness causes the switched subscriber identity card to reside in a cell with poor signal quality, reducing the signal deterioration after switching the subscriber identity card.

In some embodiments, as shown in Figure 2, the method also includes:

Step S201, determining a preset signal quality condition;

Step S202. Determine the cell configuration information according to the preset signal quality condition and the historical residency information of the plurality of subscriber identity cards.

In the embodiments of the present disclosure, the terminal may determine cell configuration information based on preset signal quality conditions. The preset signal quality condition may include information such as frequency point information of the cell, restriction conditions of RSRP and SNR, and the like. The historical camping information may include cell parameters obtained when each subscriber identity card in the terminal has camped in each cell in history, including frequency point information, RSRP, and SNR and other information. For example, the preset signal quality condition may include a minimum threshold of signal strength, a minimum threshold of signal-to-noise ratio, and the like. The terminal may determine whether the cell parameter corresponding to the cell where the history resides satisfies the above-mentioned preset signal quality condition based on the historical residency information of multiple subscriber identification cards, and if so, may save the relevant information of the corresponding cell in the cell configuration In the information, if it is not satisfied, it may not be stored in the cell configuration information. It can be understood that the preset signal quality condition may include multiple parameter thresholds or value ranges, and it may be stipulated that when a cell parameter satisfies which of them or conditions corresponding to those parameters, the preset signal quality condition is met.

In this way, when the terminal switches the subscriber identity card, it can select the cell to camp on based on the cell configuration information that has been screened by the preset signal quality conditions, thereby reducing the situation of camping on a cell whose signal quality does not meet the preset signal quality conditions , so that both the subscriber identity card after the handover and the cell where the subscriber identity card before the handover resides meet the preset signal quality conditions as much as possible.

In some embodiments, the determining the cell configuration information according to the historical residency information of a plurality of the subscriber identity cards satisfying the preset signal quality condition includes:

According to the historical resident information of each subscriber identification card, determine the configuration information corresponding to each subscriber identification card;

The cell configuration information is determined according to the configuration information that satisfies the preset signal quality condition among the plurality of configuration information corresponding to the plurality of subscriber identity cards.

During the use of the terminal, each subscriber identity card may experience that each subscriber identity card resides in different cells at different stages. Therefore, corresponding configuration information may be determined for each subscriber identity card's historical residency information. The configuration information can be the parameter information needed when the subscriber identity card camps on the corresponding cell, for example, it can include the cell parameters or parameter sets of the cell where the history is camped on, including frequency point information, RSRP and SNR information; it can also include historical camping information. The cell ID, channel information, power information, etc. required for staying in the cell; for example, for a dual-card mobile phone, the corresponding configuration information is stored based on card 1 and card 2 respectively. The configuration information here can store the historical resident information owned by each subscriber identity card or corresponding within a preset period of time.

Then, based on the preset signal quality condition, the configuration information corresponding to each of the plurality of subscriber identity cards is screened, and the configuration information satisfying the preset signal quality condition is selected to form the above cell configuration information. Therefore, the cell configuration information includes the configuration information corresponding to the cells that meet the preset signal quality conditions among the cells where multiple subscriber identity cards have been camped on in history, that is, the multiple Parameter information required by the terminal when the cell is camped on.

In this way, when the terminal switches the subscriber identity card, according to the cell configuration information, compared with the domestic configuration information of the switched subscriber identity card, the cell selection can be performed in a larger range, and the signal quality of the selectable cell Better, the efficiency of cell selection is improved, and it is convenient to quickly camp in a cell with better signal quality.

In some embodiments, the determining the cell configuration information according to the historical residency information of the plurality of subscriber identity cards satisfying the preset signal quality condition includes:

When any of the subscriber identity cards is camped in a cell, acquiring cell information of the cell where the cell resides;

determining whether the cell information satisfies the preset signal quality condition;

If the cell information satisfies the preset signal quality condition, updating the cell configuration information according to the cell information.

In the embodiment of the present disclosure, the terminal may update the configuration information of the cell when any subscriber identity card resides in the cell. When any subscriber identity card resides in a cell, the terminal can first judge whether the current cell satisfies the preset signal quality condition, and if so, it can update the cell configuration information according to the cell information of the current cell; The signal quality is poor, so the cell information of the current cell can be ignored and not stored, thereby reducing the possibility that the current subscriber identity card or other subscriber identity cards reside in the cell with poor signal quality during subsequent use.

In some embodiments, the determining the cell where the subscriber identity card resides after switching according to the cell configuration information includes:

Search for at least one cell within the current coverage;

Finding a cell that matches the cell configuration information among the searched cells;

In the matched cells, determine the cell where the switched subscriber identity card resides.

During the process of switching the subscriber identity card, the terminal can search for cells within the range where the terminal is located. When at least one cell is found, it can be matched based on the pre-stored cell configuration information of the terminal. If there is a matching cell, it means that the terminal has camped on this cell before, so it can quickly camp on this cell, reducing the need for camping. signaling interaction.

In some embodiments, the method also includes:

In response to no cell matching the cell configuration information among the searched cells, according to a preset signal quality condition, determine the cell where the switched subscriber identity card resides among the searched cells.

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

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

Of course, if the terminal only finds one cell, it can directly camp on the cell.

Embodiments of the present disclosure also provide the following examples:

The cell search and cell selection process of SA is shown in Figure 3. First, the PLMN (Public Land Mobile Network, public land mobile network) selection is selected. After selecting a suitable PLMN, the cell selection begins. The cell selection process first requires storage information cell selection The process of storing information The cell selection process is to scan the frequency according to the frequency point list information stored by the UE to find the SA cell, which can speed up the process of cell selection. If you find a suitable SA cell that can be camped on, you can just camp on normally , otherwise an initial cell selection process is required. The initial cell selection process is that the UE does not know any frequency point information. The UE scans all the frequency points in each frequency band to find the strongest SA cell according to the frequency band index sent to the physical layer by the upper layer. If a suitable SA cell is found cell, the UE normally camps on, otherwise it needs to select an acceptable SA cell to camp on, and in this case, the UE enters the restricted service state.

On the premise that the dual-card mobile phone under the same operator network only supports the single-card SA network, only the main data card can be stationed in the SA network. When switching the data main card operation, no matter what network the new data main card (hereinafter referred to as the new main card) was in before, the new main card will start the SA network process. The new master card will first select the stored information cell selection process, which will search and compare the frequency point cell information stored in the card before, including frequency point information, cell information, RSRP (Reference Signal Received Power) and SNR (Signal-to- noise ratio) and other information. Select the SA cell with the best quality. In this case, there will be an SA cell under a certain frequency that meets the camping conditions (the camping conditions are very low), even though the signal of this SA cell is very poor, the new main card will still camp on this SA cell with poor signal . This will cause a phenomenon that the signal of the SA cell where the new master card resides is much worse than the SA cell where the original data master card (hereinafter referred to as the old master card) resides under the same operator network.

For the situation that the signal of the SA cell where the new master card resides is worse than that of the SA cell where the old master card resides when dual cards (such as dual telecom cards) switch data master cards under the same operator network under the SA network, this is extremely important. It affects the user experience, so it is proposed that the dual cards under the same operator share the 5G frequency cell information when switching the main data card operation under the SA network. We set a cell selection threshold, filter out the frequency cells higher than this threshold in the dual-card storage frequency cell information, and select the SA cell in the selected frequency cell information, so that any time the other card is in During the process of camping in the SA cell, the SA cell with the best quality will be selected from the shared frequency cell information.

The cell selection method provided by the embodiment of the present disclosure is shown in Figure 4. The subscriber identity card includes card 1 and card 2. For card 1, the information of the cell where card 1 resides historically is stored, including information such as frequency point, cell ID, RSRP, and SNR. , these information can be written into the configuration file 1; for the card 2, the information of the cell where the card 2 resides in history is stored and written into the configuration file 2. In some embodiments, the above-mentioned configuration file 1 and configuration file 2 are independent of each other and cannot be shared. For example, after the main data card is switched from card 1 to card 2, card 2 will perform cell selection, but card 2 will only be in the configuration file 2 to find a suitable cell to reside in, without reading the configuration file of card 1.

In the embodiment of the present disclosure, the configuration file 3 is set by preset signal quality conditions, for example, thresholds of parameters such as RSRP or SNR are set on the upper layer of the mobile terminal as the preset signal quality conditions. The configuration file 3 includes configuration files respectively stored for the card 1 and the card 2, including a list of frequency cell information and the like. In addition, the cells stored in the configuration file 3 satisfy the aforementioned preset signal quality conditions. Therefore, SA cells with better signal quality can be screened out, and SA cells with poorer signal quality can be excluded, thereby shortening the time for selecting cells for search and comparison when switching subscriber identity cards.

In the embodiment of the present disclosure, the terminal may perform the above operations when receiving a switching instruction to switch the user identification card through a UI (User Interface, user interface).

In the embodiment of the present disclosure, when the switched subscriber identity card selects a cell, it can directly read the configuration information such as the frequency point cell in the configuration file 3, so as to search and compare these information to find the SA cell with the best quality , and then reside in the cell.

Through the above methods in the embodiments of the present disclosure, during the process of switching the main data card, that is, the subscriber identity card, the SA cell where the switched subscriber identity card resides can have better signal quality or even the signal quality of the currently available cell The best SA community. Moreover, the above method facilitates quick network deployment, saves signaling overhead, saves power consumption, and reduces signal quality degradation caused by switching subscriber identification cards, thereby improving user experience.
