In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the ^3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).

On the one hand, eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety assurance, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of the module.

RRC status

5G defines a new Radio Resource Control (RRC) state, that is, RRC_INACTIVE state, in order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. in,

1) RRC_IDLE state (referred to as idle state): mobility is based on terminal device cell selection and reselection, paging is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no terminal device context and no RRC connection on the base station side.

2) RRC_CONNECTED state (referred to as connected (connected) state for short): there is an RRC connection, and a terminal device context exists on the base station side and the terminal device side. The network side knows that the location of the terminal equipment is at the specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal equipment and the base station.

3) RRC_INACTIVE state (referred to as inactive state): Mobility is cell selection and reselection based on terminal equipment, there is a connection between the access network and the core network, and the context of the terminal equipment exists on a certain base station. The call is triggered by the radio access network (Radio Access Network, RAN). The paging area based on the RAN is managed by the RAN. The network side knows the location of the terminal device is based on the paging area level of the RAN. When the terminal device moves within the Radio Access Network Notification Area (RNA) configured by the RAN, it does not need to notify the network side, but when it moves out of the RNA, it needs to notify the network side.

The above three RRC states can be converted to each other. Among them, some RRC parameters on the terminal equipment side in the RRC inactive state are configured through the RRC release message. The main RRC parameters are as follows:

The inactive RNTI (I-RNTI) is used to identify the inactive context of the terminal device on the base station side, and is unique within the base station.

The RAN Notification Area (RNA) is an area used to control the terminal equipment to perform cell selection reselection in the RRC inactive state, and is also the initial paging area of the RAN.

The RAN paging cycle (RAN Paging cycle), that is, the RAN DRX cycle, is used to calculate the paging occasion of the RAN initial paging.

A timer for periodic RAN notification area update, that is, a periodic location update timer T380.

Next hop Chaining Counter (NCC), used to determine the secret key used in the RRC connection recovery process.

When the terminal equipment moves in the RNA area, it does not need to notify the network side, and follows the mobility behavior in the RRC idle state, that is, the principle of cell selection and reselection. When the terminal device moves out of the paging area configured by the RAN, the terminal device triggers the RRC connection recovery procedure (ie, RRC resume procedure), and re-acquires the paging area configured by the RAN. When the network side needs to transmit data to the terminal equipment, that is, when downlink data arrives, the base station that saves the terminal equipment context will trigger all cells in the RAN paging area to send paging messages to the terminal equipment, so that the terminal equipment in the RRC inactive state The device can resume the RRC connection and receive data. In addition, the terminal equipment in the RRC inactive state is configured with a RAN paging area. In order to ensure the reachability of the terminal equipment in this area, the terminal equipment needs to perform periodic location update according to the period configured by the network. Scenarios that trigger the terminal device to perform RNA update include the RNAU timer timeout or the terminal device moving to an area outside the RNA.

Dual SIM Dual Standby/Dual Network Dual Standby

Dual-card dual-standby mobile phone means that a mobile phone can hold two communication cards at the same time, and both communication cards are in standby state. Dual SIM dual standby generally refers to dual SIM dual standby of the same network standard, such as dual SIM dual standby for GSM network, dual SIM dual standby for CDMA network, and dual SIM dual standby for PHS network.

Dual network dual standby means that a mobile phone can be inserted into two communication cards of different networks at the same time, and it can be turned on at the same time. Users can make, receive and send and receive text messages at will without switching networks.

At present, mobile phones generally do not support pure dual-transmission and dual-receive (referred to as dual-pass for short). Dual-transmission and dual-reception means that the mobile phone simultaneously transmits and receives data on two networks through two communication cards. Generally speaking, most mobile phones only support single-transmission and single-receipt or single-transmission and dual-receipt, which means that the mobile phone can only perform the business on one communication card at a certain time. However, the realization of dual-pass is a trend in the development of mobile phones in the future. In 5G, for two communication cards of a mobile phone that supports dual-card dual-standby or dual-network dual-standby, one communication card can reside in the LTE cell, and the other communication card can reside in the NR cell; Each communication card resides in the NR cell. On the other hand, the two communication cards may be communication cards of the same operator, or may be communication cards of different operators.

At present, if one communication card in a dual-SIM mobile phone is conducting business, and the other communication card also needs to conduct business or need to perform signaling interaction with the network, there will be a communication conflict between the two communication cards. How to deal with the other communication card? The communication of the communication card needs to be solved. To this end, the following technical solutions of the embodiments of the present application are proposed.

The following embodiments are described by taking the terminal device having two communication cards as an example, but the present invention is not limited thereto, and the solution with more than two communication cards is also applicable to the technical solutions of the embodiments of the present application.

The registration is performed on the network, and the second communication card is registered on the second network.

It should be noted that the embodiments of the present application do not limit the types of the first communication card and the second communication card. For example, both the first communication card and the second communication card are subscriber identity module (Subscriber Identity Module, SIM) cards. For example, the first communication card and the second communication card are both Universal Subscriber Identity Module (USIM) cards. For example, the first communication card is a SIM card, and the second communication card is a USIM card. For example, the first communication card is a USIM card, and the second communication card is a SIM card. On the other hand, the embodiments of the present application do not limit the network types supported by the first communication card and the second communication card. For example, the first communication card supports an LTE network (that is, the first base station corresponding to the first communication card is an LTE base station), The second communication card supports the NR network (that is, the second base station corresponding to the second communication card is an NR base station). For example, both the first communication card and the second communication card support the NR network (that is, the second base stations corresponding to the first communication card and the second communication card and the second communication card are all NR base stations). On the other hand, the embodiments of the present application do not limit the operators to which the first communication card and the second communication card belong. For example, the first communication card and the second communication card may belong to the same operator or may belong to different operators. .

It should be noted that the communication between the terminal device and the first network is realized through the first communication card, and the communication between the terminal device and the second network is realized through the second communication card. For example, there are two USIM cards in the terminal device, which are USIM-A card and USIM-B card respectively. The terminal device can communicate with the first network through the USIM-A card, and the terminal device can communicate with the second network through the USIM-B card.
