When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. Rather, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

The cell reselection method provided in the present disclosure can be applied to the wireless communication system shown in FIG. 1. As shown in Figure 1, the terminal accesses the network through a network device such as a base station, and the network device and the core network complete the backhaul and forward transmission of data to perform various communication services.

It is understandable that a wireless communication system is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA) , Frequency Division Multiple Access (FDMA), Orthogonal Frequency-Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (Single Carrier FDMA, SC-FDMA), Carrier Sense Multiple access/conflict avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to different network capacity, speed, delay and other factors, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called a new wireless network ( New Radio, NR). For the convenience of description, the present disclosure sometimes simply refers to a wireless communication network as a network or a system. The network in the present disclosure may include a radio access network (Radio Access Network, RAN) and a core network (Core Network, CN). The network includes a network device, and the network device may be, for example, a wireless access network node, a core network device, and the like. Among them, the radio access network node may also be called a base station. The network can provide network services for the terminal through network equipment, and different operators can provide different network services for the terminal. It can also be understood that different operators correspond to different operator networks. It should be understood that, in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited. In the present disclosure, the network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell). Wherein, the network equipment provides services for the cell, and the terminal communicates with the network equipment through transmission resources (for example, frequency domain resources) used by the cell, and the cell may be a cell corresponding to the network equipment (for example, a base station). Among them, the cell may belong to a base station. In the following embodiments of the present disclosure, the cell and the base station are often used interchangeably, and those skilled in the art should understand the meaning.

A terminal, which can also be called User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc., is a device that provides users with voice and/or data connectivity. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phone), Pocket Computers (Pocket Personal Computer, PPC), handheld computers, Personal Digital Assistants (PDAs), notebook computers, tablet computers, wearable devices, or Vehicle equipment, etc.

The wireless communication system shown in FIG. 1 may include multiple terminals. The present disclosure is applicable to scenarios where a terminal (multi-card terminal) installed with multiple SIM cards communicates with the network. Among them, the SIM card may also be referred to as a subscriber identification module (Subscriber Identification Module), smart card, etc. SIM card information is stored on the SIM card, and the SIM card information may include, for example, user information, encrypted keys, and user phone book content. For example, the International Mobile Subscriber Identification Number (IMSI) is stored for the network to perform identity authentication. The SIM card can be installed in the terminal and has an operator network to which the SIM card belongs.

The present disclosure mainly relates to a communication scenario in which a multi-card terminal performs cell reselection. In related technologies, a multi-card terminal will apply for an International Mobile Equipment Identity (IMEI) number equivalent to the number of installed SIM cards, and each IMSI corresponds to an IMEI. When the terminal resides on the network, the network will perform identity verification. When a multi-card terminal installed with multiple SIM cards performs cell reselection, the network regards different SIM cards as different terminals, and each of the multiple SIM cards performs cell reselection separately. When the terminal performs cell reselection, it needs to measure the signal strengths of multiple neighboring cells and select them according to the rules set by the base station, and this measurement process consumes the power of the terminal.

In view of this, the present disclosure provides a method for cell reselection. In the method for cell reselection, priorities are set for multiple SIM cards of a multi-card terminal, and the multiple SIM cards are selected according to the priority of the SIM cards.

In step S11, the priority configuration information of multiple SIM cards is determined.

The multiple SIM cards described in this disclosure are installed on the same terminal. The priority of multiple SIM cards installed on the same terminal can be configured by the core network device.

In an implementation manner, the core network device in the present disclosure can obtain the SIM card information of multiple SIM cards installed on the multi-card terminal. For example, the SIM card information of multiple SIM cards is acquired based on the attach request (attach request) signaling sent by the terminal to the mobility management entity (MME). Or obtain the SIM card information of multiple SIM cards based on the registration request (registration request) signaling sent by the terminal to the Access and Mobility Management Function (AMF). Among them, the SIM card information may be information that distinguishes users, information about the slot where the SIM card is installed, information about the level attribute of the SIM card, identification information of the SIM card, and so on.

After the core network device determines that a terminal is a multi-card terminal, and obtains the SIM card information of the multiple SIM cards installed on the multi-card terminal, it can set the priority of the multiple SIM cards according to the SIM card information of the multiple SIM cards And determine the priority configuration information of the multiple SIM cards. Wherein, the priority configuration information of the SIM card includes the priorities of multiple SIM cards. In the present disclosure, the priority configuration information of the SIM card and the priority of the SIM card are sometimes used interchangeably, and those skilled in the art should understand the meaning.

In the present disclosure, when multiple SIM card priorities are set according to the SIM card information of multiple SIM cards, for example, multiple SIM card priorities may be set according to the information included in the SIM card information for distinguishing users. For example, in the present disclosure, the priority of multiple SIM cards is set according to the level attribute information included in the SIM card information. Among them, the level attribute of the SIM card is usually set by the operator and stored in the SIM card information. For example, the level attribute can be group user level, ordinary user level, etc. The priority of the SIM card of the group user level can be set higher than SIM card priority of the normal user level. For another example, the present disclosure may also set the priority of multiple SIM cards according to the SIM card slot installed, for example, the priority of the SIM card installed in the main card slot is set higher than the priority of the SIM card installed in the secondary card slot . The present disclosure does not limit the specific rules for setting the priority of the SIM card. For example, it can be set randomly, or it can be set according to a set rule.

It is understandable that the multiple SIM cards set with priority in the present disclosure may also be all the SIM cards installed on the terminal, or some of them.

Generally, when multiple SIM cards belonging to the same operator's network perform cell reselection, it is easier to implement communication using the same cell based on base station location, cell frequency, and measurement correlation. Therefore, in the present disclosure, priority can be set for multiple SIM cards installed in the same terminal and belonging to the same operator network.

In step S12, the priority configuration information of multiple SIM cards is sent.

In the present disclosure, after the core network device determines the priority configuration information of multiple SIM cards, it sends the priority configuration information, so that the terminal receiving the priority configuration information can select the cell reselection based on the priority configuration information. The SIM card uses the selected target SIM card for cell reselection, which can save the power of the terminal.

In an exemplary embodiment, in the present disclosure, priority configuration information of multiple SIM cards is sent based on a non-access stratum (NAS) message. For example, the priority configuration information of multiple SIM cards is sent through attach accept signaling sent by the MME. Or send the priority configuration information of multiple SIM cards through registration acceptance signaling sent by AMF. Or the priority configuration information of multiple SIM cards is sent to a wireless access point such as a base station, and the wireless access point such as the base station sends the priority configuration information of multiple SIM cards through wireless signaling.

Or obtain the priority configuration information of multiple SIM cards through the registration accept signaling sent by AMF. Or obtain the priority configuration information of multiple SIM cards through wireless signaling sent by the wireless access point.

In an exemplary embodiment, in the present disclosure, multiple SIM cards are installed on the same terminal and belong to the same operator's network. The multiple SIM cards may be all SIM cards installed in the terminal, or part of the SIM cards.

In step S22, a target SIM card is selected from multiple SIM cards according to the priority configuration information, and the selected target SIM card is used to perform cell reselection.

In the present disclosure, the SIM card for cell reselection is selected among multiple SIM cards in the order of priority from high to low according to priority configuration information. For example, in the present disclosure, the SIM card with the highest priority can be selected for cell reselection.

Wherein, the number of target SIM cards selected in the present disclosure may be one or more.

Further, in the present disclosure, after the selected target SIM card is used for cell reselection, the cell reselection result is sent to other SIM cards, and the other SIM cards use the cell selected by the selected target SIM card as the reselection result according to the cell reselection result. The selected cell. Among them, the other SIM cards are SIM cards other than the SIM card for cell reselection among the multiple SIM cards. Further, in the present disclosure, after obtaining the priority configuration information, the terminal can determine the status of each SIM card set with priority, and select the SIM card for cell reselection among the SIM cards in the idle state. For example, according to the priority configuration information, the SIM card with the highest priority is selected among the SIM cards in the idle state.

In the present disclosure, the terminal selects the target SIM card among multiple SIM cards according to the priority configuration information, and uses the selected target SIM card to perform cell reselection, which can save the power of the terminal.

The core network device determines the priority configuration information of the SIM card according to the SIM card information of the multiple SIM cards. For the implementation process of determining the priority configuration information by the core network device, reference may be made to the description of the foregoing embodiment, which is not repeated here.
