Description

Technical Field

[0001] The present disclosure relates to communication technology, and in particular to a cell selection method, device, terminal, and storage medium. Background Art

[0002] In wireless communications of mobile terminals, continuous communication services are provided to mobile terminals through wireless cellular networks. A wireless cellular network is formed by the coverage of cells distributed in different locations. Mobile terminals need to reside in a cell and establish a communication connection with the cell's network equipment to achieve wireless communication. When a mobile terminal moves to the edge of a cell or is turned on, it needs to switch to a new cell and reside there. The terminal needs to select a cell based on the user identification card. However, in a dual-SIM phone, when the mobile terminal switches the user identification card (SIM), the signal of the cell selected by the switched user identification card may be worse than the signal of the cell where the original user identification card resides, resulting in a poor user experience.

[0054] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0055] Figure 1 is a flow chart of a cell selection method according to an exemplary embodiment, the method is applied to a terminal including multiple user identification cards, such as Figure 1 As shown, the method includes:

[0056] Step S101: In response to a terminal switching a subscriber identity card for data communication, reading pre-stored cell configuration information of the terminal; wherein the cell configuration information is determined based on historical resident information of a plurality of subscriber identity cards;

[0057] Step S102: Determine the cell where the switched subscriber identity card resides according to the cell configuration information.

[0058] In the embodiment of the present disclosure, the terminal may determine the cell configuration information according to the historical residency information of multiple subscriber identification cards. That is, the cell configuration information pre-stored in the terminal includes parameters related to the historical residency information of each of the multiple subscriber identification cards.

[0059] When switching the subscriber identity card, the terminal needs to select a cell for the switched subscriber identity card and reside in the new cell.

[0060] In one embodiment, cell search is the process by which a UE (User Equipment) synchronizes time and frequency with a cell and detects a cell ID. The cell selection process of the terminal includes two cases: stored information cell selection and initial cell selection.

[0061] The stored information cell selection process requires stored information related to carrier frequency and cell parameters. Retrieve relevant cell information from previous measurement control information or from pre-existing system messages, which can help speed up the cell selection process. The stored information unit selection process is as follows:

[0062] First, the terminal searches for a suitable cell on a known carrier frequency;

[0063] Second, if the terminal finds a suitable cell, it selects the cell to camp on;

[0064] Third, if the terminal fails to find a suitable cell, it initiates an initial cell selection process.

[0065] The initial cell selection process does not require the terminal to pre-determine which frequencies are available. For example, the terminal scans all carrier frequencies in the 5G band to find a suitable cell. The terminal searches only for the strongest cell on each carrier frequency. 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 the cell to camp on.

[0066] For terminals with multiple SIM cards, when switching SIM cards, the terminal needs to perform cell selection for the SIM card after switching. For example, for dual-SIM phones under the same operator's network, when only a single SIM card SA (Standalone) is supported, only the data primary SIM card can reside on the SA network. If the SIM card is switched, the data primary SIM card will be switched. At this time, regardless of the network the SIM card was originally in or whether it was not connected to the network, the SA network residency process needs to be started. The SIM card after switching will first perform a stored information cell selection process. This process searches and compares the frequency cell information pre-stored for the SIM card, including cell information such as frequency information, cell ID, RSRP (Reference Signal Received Power), and SNR (Signal-to-Noise Ratio), and selects the SA cell with the best quality. In this case, there may be an SA cell at a certain frequency that meets the residency conditions, but the residency conditions are very low, causing the SIM card after switching to reside in an SA cell with poor signal quality.

[0067] Therefore, in the embodiment of the present disclosure, the terminal pre-stores historical residency information based on multiple user identification cards. When switching a user identification card, the terminal does not search for a cell based on the historical residency information of the switched user identification card, but selects a resided cell based on the historical residency information of the multiple user identification cards. In this way, a cell with better signal quality can be selected for residency based on the cells where the multiple user identification cards have historically resided. Therefore, it is possible to avoid the switched user identification card residing in a cell with poor signal quality due to incomplete information, thereby reducing the situation where the signal deteriorates after switching the user identification card.

[0068] In some embodiments, as Figure 2 As shown, the method further includes:

[0069] Step S201: Determine a preset signal quality condition;

[0070] Step S202: Determine the cell configuration information according to the preset signal quality condition and the historical residency information of the plurality of subscriber identification cards.

[0071] In an embodiment of the present disclosure, a terminal may determine cell configuration information based on preset signal quality conditions. The preset signal quality conditions may include information such as frequency information, RSRP, and signal-to-noise ratio (SNR) restrictions for the cell. Historical resident information may include cell parameters acquired by each subscriber identity card in the terminal during its historical resident time in each cell, including frequency information, RSRP, and SNR. For example, the preset signal quality conditions may include a minimum threshold for signal strength, a minimum threshold for signal-to-noise ratio, and the like. Based on the historical resident information of multiple subscriber identity cards, the terminal may determine whether the cell parameters corresponding to the historically resident cell meet the preset signal quality conditions. If so, the relevant information of the corresponding cell may be stored in the cell configuration information. If not, the relevant information may not be stored in the cell configuration information. It is understood that the preset signal quality conditions may include thresholds or value ranges for multiple parameters, and may specify which parameter or parameters' corresponding conditions must be met for the cell parameter to be considered to meet the preset signal quality conditions.

[0072] In this way, when the terminal switches the user identification card, it can select a cell to reside in based on the cell configuration information that has been screened by the above-mentioned preset signal quality conditions, thereby reducing the situation of residing in a cell whose signal quality does not meet the preset signal quality conditions, so that the cells where the user identification card after switching and the user identification card before switching reside both meet the preset signal quality conditions as much as possible.

[0073] In some embodiments, determining the cell configuration information based on historical residency information of a plurality of subscriber identification cards that meet the preset signal quality condition includes:

[0074] Determine the configuration information corresponding to each user identification card according to the historical resident information of each user identification card;

[0075] The cell configuration information is determined according to configuration information that meets the preset signal quality condition among the plurality of configuration information corresponding to the plurality of subscriber identification cards.

[0076] During the use of the terminal, each user identification card may reside in different cells at different stages. Therefore, corresponding configuration information can be determined for each user identification card's historical residency information. This configuration information can be the parameter information required for the user identification card to reside in the corresponding cell. For example, it can include the cell parameters or parameter sets of the historical residency cell, including frequency information, RSRP, and SNR information; it can also include the cell identifier, channel information, and power information required for the historical residency cell. For example, for a dual-SIM phone, the corresponding configuration information is stored based on card 1 and card 2 respectively. The configuration information here can store all the historical residency information of each user identification card or the corresponding historical residency information within a preset period.

[0077] The configuration information corresponding to each of the plurality of subscriber identification cards is then screened based on the preset signal quality condition, and the configuration information that meets the preset signal quality condition is selected to form the cell configuration information. Therefore, the cell configuration information includes the configuration information corresponding to the cells that meet the preset signal quality condition among the cells where the plurality of subscriber identification cards have historically resided. This is the parameter information required by the terminal when the plurality of subscriber identification cards resided in the plurality of cells during their historical use.

[0078] In this way, when the terminal switches the user identification card, it can select a cell within a larger range based on the cell configuration information, compared to the domestic configuration information based on the user identification card after switching, and the signal quality of the selectable cell is better, which improves the efficiency of cell selection and facilitates rapid residence in a cell with better signal quality.

[0079] In some embodiments, determining the cell configuration information based on historical residency information of the plurality of subscriber identification cards that meet the preset signal quality condition includes:

[0080] When any of the user identification cards resides in a cell, obtaining cell information of the cell in which the card resides;

[0081] Determining whether the cell information meets the preset signal quality condition;

[0082] If the cell information meets the preset signal quality condition, the cell configuration information is updated according to the cell information.

[0083] In the disclosed embodiments, a terminal can update cell configuration information when any subscriber identification card resides in a cell. When any subscriber identification card resides in a cell, the terminal can first determine whether the current cell meets a preset signal quality condition. If so, the cell configuration information can be updated based on the cell information of the current cell. If not, it indicates that the signal quality of the current cell is poor, and the cell information of the current cell can be ignored and not saved, thereby reducing the possibility that the current subscriber identification card or other subscriber identification cards will reside in the cell with poor signal quality during subsequent use.

[0084] In some embodiments, determining, based on the cell configuration information, the cell in which the user identification card resides after the handover includes:

[0085] Searching for at least one cell within the current coverage area;

[0086] Searching for a cell matching the cell configuration information among the cells found;

[0087] Among the matched cells, the cell where the switched subscriber identification card resides is determined.

[0088] During the process of switching the SIM card, the terminal can search for cells within the terminal's range. Once at least one cell is found, a match is performed based on the terminal's pre-stored cell configuration information. If a matching cell exists, it indicates that the terminal has previously camped on that cell, allowing the terminal to quickly camp on that cell, reducing the signaling interaction required for the camping.

[0089] In some embodiments, the method further comprises:

[0090] In response to the absence of a cell matching the cell configuration information among the searched cells, a cell in which the switched subscriber identification card resides is determined among the searched cells according to a preset signal quality condition.

[0091] Because the terminal may move in various ways, it is possible that none of the searched cells matches the currently stored cell configuration information. In this case, the terminal can search for a cell that meets a preset signal quality condition, for example, a signal strength greater than a threshold specified by the preset signal quality condition, and reside in that cell.

[0092] In addition, if there is no cell that meets 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 highest reference signal received power, can be selected from the searched cells and reside in the cell.

[0093] Of course, if the terminal searches for only one cell, it can directly camp in the cell.

[0094] The present disclosure also provides the following examples:

[0095] The cell search and cell selection process of SA is as follows Figure 3 As shown, the first step is to select the PLMN (Public Land Mobile Network). After selecting the appropriate PLMN, the cell selection process begins. The cell selection process first involves the stored information cell selection process. The stored information cell selection process is to perform a frequency scan to select the SA cell based on the frequency list information previously stored by the UE. This can speed up the cell selection process. If a suitable SA cell is found that can be resided in, it can reside normally. Otherwise, the initial cell selection process is required. The initial cell selection process is that the UE does not know any frequency information. The UE scans all frequencies in each frequency band according to the frequency band index sent from the upper layer to the physical layer to find the strongest SA cell. If a suitable SA cell is found, it resides normally. Otherwise, it needs to select an acceptable SA cell to reside in. In this case, the UE enters a restricted service state.

[0096] In dual-SIM phones on the same carrier network, only single-SIM SA networks are supported. Only the data primary SIM can camp on the SA network. When switching the data primary SIM, the new data primary SIM (hereinafter referred to as the new primary SIM) will begin the SA network camping process, regardless of the network it was previously on. The new primary SIM will first perform a cell selection process, searching and comparing previously stored cell information, including frequency information, cell information, RSRP (Reference Signal Received Power), and SNR (Signal-to-Noise Ratio). The new primary SIM will select the SA cell with the best quality. In this case, there may be an SA cell on a certain frequency that meets the camping conditions (but the camping conditions are very low). Even though the SA cell signal is very poor, the new primary SIM will camp on this SA cell. This can result in the SA cell on the same carrier network being camped on by the new primary SIM being significantly worse than the SA cell on the old data primary SIM (hereinafter referred to as the old primary SIM).

[0097] In response to the situation where the SA cell signal of the new primary SIM card (for example, two telecom SIM cards) switching the data primary SIM card on the same operator's network in an SA network is worse than the SA cell signal of the old primary SIM card, which greatly affects the user experience, we proposed to share 5G frequency cell information with two SIM cards on the same operator when switching the data primary SIM card in an SA network. We set a cell selection threshold and filter out the frequency cells above this threshold from the frequency cell information stored by the two SIM cards. SA cells are selected from these filtered frequency cell information. In this way, whenever the other SIM card is stationed in an SA cell, it will select the SA cell with the best quality among these shared frequency cell information.

[0098] The cell selection method provided by the embodiment of the present disclosure is as follows: Figure 4 As shown, the user identification card includes card 1 and card 2. Card 1 stores information about cells that card 1 has historically resided on, including frequency, cell ID, RSRP, and SNR, and can write this information into configuration file 1. Card 2 stores information about cells that card 2 has historically resided on and writes it into configuration file 2. In some embodiments, configuration files 1 and 2 are independent of each other and cannot be shared. For example, after switching the data master card from card 1 to card 2, card 2 will perform cell selection, but card 2 will only search for a suitable cell in configuration file 2 to reside on, and will not read the configuration file of card 1.

[0099] In the disclosed embodiment, profile 3 is set based on preset signal quality conditions. For example, thresholds for parameters such as RSRP or SNR are set at the upper layer of the mobile terminal as the preset signal quality conditions. Profile 3 includes separate profiles stored for card 1 and card 2, including frequency cell information lists, etc. Furthermore, the cells stored in profile 3 meet the preset signal quality conditions. Therefore, SA cells with good signal quality can be screened out, while SA cells with poor signal quality can be eliminated, thereby shortening the time required to search and compare cells when switching user identification cards.

[0100] In the embodiment of the present disclosure, the terminal may perform the above operation when receiving a switching instruction for switching the subscriber identity card through a UI (User Interface).

[0101] In the disclosed embodiment, when the switched user identification card performs cell selection, it can directly read the configuration information such as frequency cells in the configuration file 3, thereby searching and comparing the information to find the SA cell with the best quality and then reside in the cell.

[0102] Through the above-described method in the embodiment of the present disclosure, during the process of switching the primary data card, i.e., the subscriber identity card, the SA cell where the switched subscriber identity card resides can be one with better signal quality, or even the best signal quality among the currently available cells. Furthermore, the above-described method facilitates rapid network access, reduces signaling overhead and power consumption, and reduces the degradation of signal quality caused by switching subscriber identity cards, thereby improving the user experience.
