In an optional embodiment of the present application, the communication device may include at least one of the following: a communication network element and a terminal.

In an embodiment of the present application, the communication network elements may include at least one of the following: a core network network element (CN network element) and a radio access network network element (RAN network element).

In an optional embodiment of the present application, the core network network elements may include but are not limited to at least one of the following: core network equipment, core network nodes, core network functions, core network network elements, and mobility management entities (Mobility Management Entity, MME), Access Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Serving GW (SGW), PDN Gateway ( PDN Gate Way, P-GW), Policy Control Function (Policy Control Function, PCF), Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Application Function (Application) Function, AF), centralized network configuration (Centralized network configuration, CNC).

In an optional embodiment of the present application, a radio access network (Radio Access Network, RAN) network element may include but is not limited to at least one of the following: a radio access network device, a radio access network node, a radio access network Function, Radio Access Network Unit, Third Generation Partnership Project (3GPP) Radio Access Network, Non-3GPP Radio Access Network, Centralized Unit (CU), Distributed Unit (Distributed Unit, DU), Base Station, Evolved Node B (eNB), 5G Base Station (gNB), Radio Network Controller (RNC), Base Station (NodeB), Non-3GPP Inter Working Function, N3IWF), access control (Access Controller, AC) node, access point (Access Point, AP) device or wireless local area network (Wireless Local Area Networks, WLAN) node, non-3GPP interworking function (Non-3GPP InterWorking Function, N3IWF).

A multi-card terminal (also referred to as a multi-card UE) is a device with two or more than two Subscriber Identity Module (SIM) cards. The SIM card is an electronic SIM card or a physical SIM card. From the network point of view, the same terminal device and different SIM cards constitute different UEs. In addition, the multi-card terminal may also be referred to as a multiple universal subscriber identity module (Multiple Universal Subscriber Identity Module, MUSIM) terminal.

Optionally, the SIM cards in the multi-card terminal may belong to the same operator or different operators. The wireless communication networks accessed by different SIM cards may be the same or different.

Optionally, the SIM card may include one of the following: a SIM card, a Universal Subscriber Identity Module (USIM) card, and an embedded SIM (Embedded-SIM, eSIM) card. The SIM card can also be named as another name, such as being directly called "card", which is not limited in this application.

At present, for a multiple subscriber identity module (Multiple Subscriber Identity Module, MUSIM) terminal with only a single transmission function, since the terminal cannot send uplink information to multiple networks at the same time, the terminal needs to travel back and forth between different networks. For example, when the terminal wants to go to the card A network, if the terminal is in a connection state with the card B network, the terminal needs to request the card B network to leave.

At present, there are still the following problems when the terminal requests the network to leave:

Problem 1: The network may be deployed at the same time, the RRC-based leave method and the NAS-based leave method. For example, the CN supports the NAS leave method, but some RAN network elements support the RRC signaling-based leave method. For a terminal that supports both the RRC-based departure mode and the NAS-based departure mode, how to choose the RRC-based departure mode or the NAS-based departure mode is a problem to be solved.

One way to solve the problem is to give preference to the RRC-based departure method, that is, when the terminal and/or the network supports both the RRC-based departure method and the NAS-based departure method, the terminal preferentially selects the RRC-based departure method. When the terminal and/or the network does not support the RRC-based leave method, consider the NAS-based leave method.

Question 2: For the RAN network element, it is unclear whether to execute the operation of the terminal leaving the network when it receives the leaving request sent by the terminal through RRC signaling. Because, the RAN network element also needs to know whether to allow the terminal to request to leave the network or whether to allow the terminal to leave the network based on the terminal's request.

One solution is that the CN network element informs the RAN network element whether it supports the terminal's request to leave the network.

Question 3: The RRC-based leave method may require the capability of an additional CN network element or not. For example, when the terminal requests to leave the network through RRC signaling, auxiliary information for processing downlink data and/or short messages may be provided, and this part needs the support of the CN network element. The question of how to set the above capabilities needs to be solved.

A NAS-based leave approach may or may not require additional RAN element capabilities. For example, when the terminal requests to leave the network through NAS signaling, the CN network element may request the RAN network element to set the state of the terminal to RRC inactive state, or the CN network element directly requests the RAN network element to release the connection between the terminal and the network.

In an embodiment, the RRC or RRC signaling is signaling between the AS layer of the terminal and the network (eg, a RAN network element). With the evolution of the network, the RRC or RRC signaling in this document may be changed to other names, and this application does not limit the name of the signaling between the terminal AS layer and the network (eg, RAN network element).

In an embodiment, the NAS signaling is the interaction signaling between the NAS layer of the terminal and the network (eg, CN network element). With the evolution of the network, the NAS signaling in this document may be changed to other names, and the name of the interactive signaling between the terminal NAS layer and the network (eg, CN network element) is not limited in this application.

The RRC-based leaving manner includes: 1) a manner in which the terminal requests to leave the network through RRC signaling, or 2) a manner in which the terminal AS layer triggers a request to leave the network.

The manner in which the terminal requests to leave the network through RRC signaling may include: the terminal sends a request for leaving the network to the RAN network element through RRC signaling. For the RAN network element supporting the RRC-based leave mode, it can understand the request for leaving the network sent through RRC signaling.

The non-access stratum NAS-based leaving method includes: 1) a method in which the terminal requests to leave the network through NAS signaling or 2) a method in which the terminal NAS layer triggers a request to leave the network. The request by the terminal to leave the network through NAS signaling includes: the terminal sends a request for leaving the network to the CN network element through NAS signaling. For CN network elements that support the NAS-based leaving mode, the request for leaving the network through CN signaling can be understood. For the RAN network element, the request for leaving the network sent through NAS signaling is no different from other NAS protocol data units (Protocol Data Unit, PDU).

The RAN network element transparently transmits the NAS signaling but does not understand the content of the NAS signaling.

In an optional embodiment of the present application, the leaving the network includes at least one of the following: stopping or suspending data transmission between the terminal and the network, the connection between the terminal and the network enters a disconnected state, or when the terminal leaves the network Keep the terminal connected.
