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

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

In an optional embodiment of the present application, the core network element may include, but is not limited to, at least one of the following: core network equipment, core network nodes, core network functions, core network elements, Mobility Management Entity (MME), Access Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Serving Gateway (GW, SGW), PDN Gateway (PDN Gateway ), Policy Control Function (Policy Control Function, PCF), Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), GPRS service Support Node (GPRS Support Node, SGSN), Gateway Support Node (HSS Node, GGSN), Unified Data Management (UDM), Unified Data (HSS ), Home Application Server (AF), and Application Server (AF), centralized Network Configuration (CNC).

In an optional embodiment of the present application, a Radio Access Network (RAN) Network element may include, but is not limited to, at least one of the following: radio Access Network equipment, Radio Access Network nodes, Radio Access Network functions, Radio Access Network units, 3GPP Radio Access Networks, Non-3GPP Radio Access Networks, Centralized Units (CUs), Distributed Units (DUs), bss, evolved bss (evolved Node B, eNB), 5G bss (gNB), Radio Network controllers (Radio Network controllers, RNC), bss (NodeB), Non-3GPP InterWorking functions (Non-3GPP Inter Working Function, N3IWF), Access control (Access Controller, AC) nodes, Access Point (AP) devices, or Wireless Local Area Networks (WLAN) nodes, Non-3GPP functions (Non-3GPP InterWorking Function, N3 GPP InterWorking Function, IWF).

A multi-card terminal (also referred to as a multi-card UE) is a Subscriber Identity Module (SIM) card with two or more than two SIM cards on one device. The SIM card is an electronic SIM card or a physical SIM card. From the network perspective, the same terminal device and different SIM cards form different UEs. In addition, the multi-card terminal may also be referred to as a 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 can be the same or different.

Optionally, the SIM card may include one of: SIM card, Universal Subscriber Identity Module (USIM) card, Embedded SIM (eSIM) card. The SIM card may also be named otherwise, such as directly "card," which is not intended to be limiting in this application.

Currently, for a multi Subscriber Identity Module (MUSIM) terminal with only a single function, the terminal cannot simultaneously send uplink information to Multiple networks, and therefore the terminal needs to go 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 connected state with the card B network, the terminal needs to request to leave from the card B network.

Currently, the following problems still exist when the terminal requests the network to leave:

the first problem is that: the network may deploy, RRC-based detach and NAS-based detach simultaneously. For example, the CN supports the NAS leaving mode, but part of the RAN network elements support the leaving mode based on RRC signaling. How to select the RRC-based leaving method or the NAS-based leaving method is a problem to be solved for a terminal that supports both the RRC-based leaving method and the NAS-based leaving method.

One solution to the problem is to prioritize the RRC-based detach mode, i.e., when the terminal and/or the network supports both the RRC-based detach mode and the NAS-based detach mode, the terminal preferentially selects the RRC-based detach mode. When the terminal and/or the network do not support the RRC-based leaving mode, the NAS-based leaving mode is considered.

The second problem is that: for the RAN network element, it is not clear whether to perform an operation of the terminal leaving the network when receiving a leaving request sent by the terminal through RRC signaling. Because the RAN network element also needs to know whether the terminal is allowed to request to leave the network or whether the terminal can be allowed to leave the network based on the terminal's request.

One solution is that the CN element informs the RAN element whether the RAN element supports the terminal requesting to leave the network.

The third problem is that: the RRC based leaving approach may or may not require the capability of an additional CN network element. 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, which is supported by the CN element. The problem of how to set the above capabilities needs to be solved.

The NAS-based detach approach may or may not require the capability of an additional RAN network element. 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 be an 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 one embodiment, the RRC or RRC signaling is signaling between the AS layer of the terminal and the network (e.g., RAN network element). AS the network evolves, the RRC or RRC signaling may be changed to other names, and the name of the signaling between the AS layer of the terminal and the network (e.g., RAN network element) is not limited in this application.

In one embodiment, the NAS signaling is interactive signaling between a terminal NAS layer and a network (e.g., a CN network element). As the network evolves, the NAS signaling may be changed to other names, and the name of the signaling interaction between the terminal NAS layer and the network (e.g., CN network element) is not limited in this application.

In an alternative embodiment of the present application, the first leaving mode is a mode in which the terminal requests to leave the network. The first departure mode includes: RRC-based detach, NAS-based detach.

The RRC-based leaving mode comprises the following steps: 1) the terminal requests to leave the network through RRC signaling, or 2) the terminal AS layer triggers the mode of requesting to leave the network.

The method for requesting the terminal to leave the network through the RRC signaling may include: the terminal sends a request for leaving the network to the RAN network element by RRC signaling. For RAN network elements that support RRC-based leaving, the request to leave the network sent by RRC signaling can be understood.

The non-access stratum (NAS) -based leaving mode comprises the following steps: 1) the terminal requests to leave the network through NAS signaling or 2) the terminal NAS layer triggers the mode of requesting to leave the network. The terminal requesting to leave the network through the NAS signaling comprises the following steps: the terminal sends a request for leaving the network to the CN network element through NAS signaling. For CN network elements supporting NAS-based leaving, the request for leaving the network through CN signaling can be understood. The request for leaving the network sent by NAS signaling is indistinguishable from other NAS PDUs to RAN network elements.

The RAN network element transparently passes the NAS signaling but does not understand the contents of the NAS signaling.

In an optional embodiment of the present application, the leaving the network comprises at least one of: and stopping or suspending data transmission between the terminal and the network, and enabling the connection between the terminal and the network to enter a non-connection state or keeping the terminal in a connection state during the period that the terminal leaves the network.

In one embodiment, the terminal leaves the connection of the network terminal with the network into a non-connected state.

In another embodiment, the terminal leaves the network is that the connection between the terminal and the network is kept connected, but the data transmission between the terminal and the network is stopped or suspended.

In an optional embodiment of the present application, the short-term leaving comprises leaving means to maintain a connected state and/or a suspension of data transfer;

in an alternative embodiment of the present application, the long-term leaving includes a leaving manner to enter a non-connected state.

In an alternative embodiment of the present application, the data comprises control plane data and/or user plane data. The control plane data includes signaling (e.g., RRC signaling or NAS signaling).

In one embodiment, the network supporting the RRC based detach mode includes at least one of:

all RAN network elements in the network support a departure mode based on RRC;

all CN elements in the network support RRC-based leaving.

In one embodiment, the network supporting the NAS-based detach includes at least one of:
