Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same 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.

The cell reselection method provided by the present disclosure may be applied to the wireless communication system shown in fig. 1. As shown in fig. 1, a terminal is accessed into a network through a network device such as a base station, and the network device and a core network complete the backhaul and forward transfer of data to perform various communication services.

It is understood that a wireless communication system is a network that provides wireless communication functions. Wireless communication systems may employ 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 FDMA, carrier Sense Multiple Access with Collision Avoidance (SC-FDMA). Networks can be classified into 2G (english: generation) networks, 3G networks, 4G networks or future evolution networks, such as 5G networks, according to factors such as capacity, rate and delay of different networks, and the 5G networks can also be referred to as New Radio Networks (NR). For ease of description, this disclosure will sometimes simply refer to a wireless communication network as a network or system. In the present disclosure, a Network may include a Radio Access Network (RAN) and a Core Network (Core Network, CN). Included in the network is a network device, which may be, for example, a radio access network node, a core network device, etc. The radio access network node may also be referred to as a base station, among others. The network can provide network services for the terminal through the network device, different operators can provide different network services for the terminal, and different operators can also be understood as different operator networks corresponding to different operators. It should be understood that, in the embodiments of the present disclosure, the specific technology and the specific device form adopted by the network device are not limited. In the present disclosure, a network device may provide communication coverage for a particular geographic area and may communicate with terminals located within that coverage area (cell). The network device provides a service for a cell, and a terminal communicates with the network device through a transmission resource (for example, a frequency domain resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station). Wherein a cell may belong to a base station. In the following embodiments of the present disclosure, cells and base stations are often used interchangeably, and those skilled in the art will understand the meaning.

A Terminal, which may also be referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or a vehicle-mounted device, etc.

A plurality of terminals may be included in the wireless communication system shown in fig. 1. The present disclosure is applicable to a scenario in which a terminal (multi-card terminal) mounted with a plurality of SIM cards communicates with a network. The SIM card may also be called a Subscriber identity Module (Subscriber identity Module) or a smart card. The SIM card stores SIM card information, which may include information for distinguishing a user, an encrypted key, and contents of a user's phone book, for example. For example, an International Mobile Subscriber Identity (IMSI) is stored for the network to perform identity authentication. The SIM card may be installed in the terminal and have the operator network to which the SIM card belongs.

The present disclosure generally relates to communication scenarios for cell reselection by multi-card terminals. In the related art, a multi-card terminal applies for International Mobile Equipment Identity (IMEI) numbers corresponding to the number of installed SIM cards, and each IMSI corresponds to an IMEI. When the terminal resides in the network, the network can perform identity authentication. When a multi-card terminal provided with a plurality of SIM cards performs cell reselection, a network considers different SIM cards as different terminals, and each SIM card in the plurality of SIM cards performs cell reselection separately. When a terminal reselects a cell, it needs to measure the signal strengths of multiple neighboring cells and select according to the rules set by the base station, and the measurement process consumes the power of the terminal.

In view of this, the present disclosure provides a cell reselection method, in which priorities are set for a plurality of SIM cards of a multi-card terminal, and a target SIM card for cell reselection is selected from the plurality of SIM cards according to the priorities of the SIM cards. And the selected target SIM card is utilized to reselect the cell, and the cell is reselected separately relative to all the SIM cards, so that the electric quantity of the terminal can be saved.

Fig. 2 is a flowchart illustrating a cell reselection method according to an exemplary embodiment, where as shown in fig. 2, the cell reselection method is used in a core network device and includes the following steps S11 and S12.

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

The plurality of SIM cards in this disclosure are installed on the same terminal. The priorities of the plurality of SIM cards installed on the same terminal may be configured by the core network device.

In one embodiment, in the present disclosure, the core network device may obtain SIM card information of a plurality of SIM cards installed on the multi-card terminal. For example, the SIM card information of the multiple SIM cards is obtained based on an attach request (attach request) signaling sent by the terminal to a Mobility Management Entity (MME). Or acquiring the SIM card information of the plurality of SIM cards based on a registration request (registration request) signaling sent by the terminal to an Access and Mobility Management Function (AMF). The SIM card information may be information for distinguishing a user, card slot information for installing the SIM card, level attribute information of the SIM card, identification information of the SIM card, and the like.

The core network equipment determines that a certain terminal is a multi-card terminal, and after the SIM card information of a plurality of SIM cards installed on the multi-card terminal is obtained, the priority of the plurality of SIM cards can be set according to the SIM card information of the plurality of SIM cards, and the priority configuration information of the plurality of SIM cards is determined. The priority configuration information of the SIM cards comprises the priorities of the plurality of SIM cards. The priority configuration information of the SIM card and the priority of the SIM card in the present disclosure may sometimes be used interchangeably, and the meaning thereof will be understood by those skilled in the art.

When the plurality of SIM card priorities are set according to the SIM card information of the plurality of SIM cards in the present disclosure, for example, the plurality of SIM card priorities may be set according to information for distinguishing users included in the SIM card information. For example, the priorities of the plurality of SIM cards are set according to the level attribute information included in the SIM card information in the present disclosure. 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 may be a group user level, a common user level, and the like, and the SIM card priority of the group user level may be set to be higher than the SIM card priority of the common user level. For another example, the present disclosure may also set priorities of multiple SIM cards according to the card slots in which the SIM cards are installed, for example, setting a priority of a SIM card installed in a primary card slot higher than a priority of a SIM card installed in a secondary card slot. The rules according to which the priority of the SIM card is specifically set are not limited in this disclosure. For example, the setting may be performed randomly or according to a set rule.

It is to be understood that the plurality of SIM cards prioritized in this disclosure may also be all or part of the SIM cards installed on the terminal.

Generally, when a plurality of SIM cards belonging to the same operator network perform cell reselection, the same cell is used for communication based on the base station location, the cell frequency, the measurement correlation, and the like, which is easier to implement. Therefore, in the present disclosure, priorities may be set for a plurality of SIM cards installed in the same terminal and belonging to the same operator network.

In step S12, priority configuration information of the plurality of SIM cards is transmitted.

In the present disclosure, after determining the priority configuration information of a plurality of SIM cards, the core network device sends the priority configuration information, so that a terminal receiving the priority configuration information can select an SIM card for cell reselection according to the priority configuration information, and perform cell reselection by using the selected target SIM card, which can save the electric quantity of the terminal.

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

Fig. 3 is a flowchart illustrating a cell reselection method according to an exemplary embodiment, where the cell reselection method is used in a terminal, and a plurality of SIM cards are installed on the terminal, as shown in fig. 3, and the method includes the following steps S21 and S22.

In step S21, priority configuration information of a plurality of SIM cards is acquired.

In the present disclosure, priority configuration information of a plurality of SIM cards may be acquired based on NAS messages. For example, the priority configuration information of multiple SIM cards is obtained through attach accept signaling sent by the MME. Or acquiring the priority configuration information of the plurality of SIM cards through a registration accept signaling sent by the AMF. Or acquiring the priority configuration information of the plurality of SIM cards through wireless signaling sent by the wireless access point.

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

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

According to the priority configuration information, the SIM cards for cell reselection are selected from the plurality of SIM cards according to the sequence from high priority to low priority. For example, the highest priority SIM card may be selected for cell reselection in the present disclosure.

The number of the target SIM cards selected in the present disclosure may be one or multiple.

Further, in the present disclosure, after the cell reselection is performed by using the selected target SIM card, the cell reselection result is sent to other SIM cards, and according to the cell reselection result, the other SIM cards use the cell selected by the selected target SIM card as the reselected cell. And the other SIM cards are the SIM cards except the SIM card for cell reselection in the plurality of SIM cards. Further, in the present disclosure, after the terminal acquires the priority configuration information, the state of each SIM card with a priority may be determined, and an SIM card for cell reselection is selected from the SIM cards in an idle state. For example, according to the priority configuration information, the SIM card with the highest priority is selected from the SIM cards in the idle state.

According to the method and the device, the terminal selects the target SIM card from the plurality of SIM cards according to the priority configuration information, and performs cell reselection by using the selected target SIM card, so that the electric quantity of the terminal can be saved.

In one embodiment, the priority configuration information in the present disclosure may be determined by a core network device.

The core network device may determine priority configuration information of the multiple SIM cards according to SIM card information of the multiple SIM cards.

The terminal can report the SIM card information of a plurality of SIM cards, and the SIM card information of the plurality of SIM cards is used for the core network equipment to determine the priority configuration information.

Fig. 4 is a flowchart illustrating a cell reselection method according to an exemplary embodiment, where the cell reselection method is used in a terminal, and a plurality of SIM cards are installed on the terminal, as shown in fig. 4, and the method includes the following steps S31 to S33.

In step S31, SIM card information of multiple SIM cards is reported.

In the disclosure, a plurality of SIM cards installed in a terminal may report their respective SIM card information respectively, or the terminal may report the SIM card information of the plurality of SIM cards in a unified manner, so that the core network device determines that the terminal is a multi-card terminal and determines the SIM card information of the plurality of SIM cards. And the core network equipment determines the priority configuration information of the SIM cards according to the SIM card information of the plurality of SIM cards. The implementation process of determining the priority configuration information by the core network device may refer to the description of the above embodiments, and is not described herein again.

Or the SIM card information of a plurality of SIM cards can be sent based on the registration request signaling sent by the terminal to the AMF.

In step S32, priority configuration information of a plurality of SIM cards is acquired.

In step S33, a target SIM card is selected from the multiple SIM cards according to the priority configuration information, and cell reselection is performed using the selected target SIM card.

In step S34, a cell reselection result obtained after the target SIM card performs cell reselection is sent to other SIM cards, and the other SIM cards take the cell selected by the target SIM card as the reselected cell according to the cell reselection result.

According to the method and the device, the terminal reports the SIM card information, and the core network equipment sets the priority of the SIM card according to the SIM card information, so that the determined priority configuration information of the SIM card is more accurate. The terminal selects the SIM card for cell reselection according to the priority configuration information.

Fig. 5 is a flow chart illustrating a method of cell reselection according to an example embodiment. The cell reselection method shown in fig. 5 is applied to a core network device. In fig. 5, steps S41 and S42 are the same as steps S11 and S12 in the cell reselection method described in fig. 2, and are not repeated here, and only differences will be described.

In step S43, priorities of the plurality of SIM cards are adjusted.

In the disclosure, the core network device can adjust the priority of the SIM card according to actual conditions. In one embodiment, the core network device may adjust the priority of the SIM card based on a user trigger, for example, the user may select a SIM card for cell reselection, trigger the core network device to adjust the priorities of multiple SIM cards based on a user selection instruction, and increase the priority of a target SIM card selected by the user. In another embodiment, the core network device may adjust the priority of the SIM card based on the communication status of the SIM card. For example, if the core network device monitors that the SIM card with a higher priority level is in a busy state or an arrearage state, the core network device may adjust the priorities of the multiple SIM cards to reduce the priority of the SIM card in the busy state or the arrearage state.

In step S44, the priority adjustment information of the plurality of SIM cards is transmitted.

In the disclosure, after the core network device adjusts the priorities of the plurality of SIM cards, the adjusted priorities of the SIM cards can be sent to the terminal. Wherein, the priority adjustment information of the plurality of SIM cards can be sent through NAS layer signaling. For example, the priority adjustment information of the plurality of SIM cards is transmitted based on a user equipment Configuration Update Command (UE Configuration Update Command).

In fig. 6, steps S51 and S52 are the same as steps S21 and S22 in the cell reselection method described in fig. 3, and are not repeated here, and only the differences will be described.

In step S53, priority adjustment information of a plurality of SIM cards is acquired.

In the present disclosure, the priority adjustment information of the plurality of SIM cards may be acquired through NAS layer signaling. For example, priority adjustment information of a plurality of SIM cards is acquired based on the UEConfiguration Update Command.

In step S54, the priority configuration information of the plurality of SIM cards is re-determined according to the priority adjustment information.

In this disclosure, after the terminal re-determines the priority configuration information of the multiple SIM cards, the terminal may return to step S52, and select a SIM card for cell reselection from the multiple SIM cards by using the re-determined priority configuration information of the multiple SIM cards.
