When a layer 2 (Layer 2, L2) relay terminal (relay UE) provides relay services for a remote terminal (remote UE), it may be in various special states, including but not limited to: in 5G mobile Sexual management - de-register (5GMM-DEREGISTRATED); in non-allow area; in non-suitable cell, etc.

However, in related technologies, there is no regulation on how the relay UE in the above-mentioned special state enters the connected state. The service request process used in the prior art cannot be applied to all scenarios, which leads to the relay UE providing relay services in some scenarios. Failed to enter connection state.

In order to facilitate a better understanding of the embodiments of this application, the following technical points are introduced first:

1. About Connection Management

If the relay UE (or described as L2 UE-to-Network relay UE) wants to provide relay service for remote UE (or described as L2 UE-to-Network remote UE), the relay UE must enter the connection management-connection (CM-CONNECTED ) state (or described as 5G Mobility Management-Connection (5GMM-CONNECTED) mode).

However, when the relay UE needs to enter the CM-CONNECTED state, there may be many different sub-states:

a) 5G Mobility Management - Registration (5GMM-REGISTERED) status;

b) 5GMM-DEREGISTERED state;

For a), if the relay UE is in the 5GMM-REGISTERED state, the relay UE can directly enter the CM-CONNECTED state by initiating a service request (service request) process. However, in the registered state, how the relay UE in the non-allowed area (non-allowed area) and non-suitable cell (non-suitable cell) enters the connected state when it needs to provide relay services is an urgent problem to be solved. This has not been studied and standardized.

For b), the core network has deleted the context of the relay UE, and the corresponding connection and resources have not been reserved between the relay UE and the core network. At this time, the relay UE is not reachable (not reachable) to the core network. How the relay UE enters the CM-CONNECTED state when it needs to provide relay services is an urgent problem to be solved.

2. About 5G Mobility Management-Registration, Non-Allowed Service (5GMM-REGISTERED.NON-ALLOWED-SERVICE)

The 5GMM-REGISTERED state can include multiple sub-states, such as:

a) 5G Mobility Management - Registration, Public Land Mobile Network Search (5GMM-REGISTERED.PLMN-SEARCH):

b) 5GMM-REGISTERED.NON-ALLOWED-SERVICE; and

c) 5G mobility management-registration, no cell available (5GMM-REGISTERED.NO-CELL-AVAILABLE).

When the Relay UE is in a non-allowed area, it may be in two states: 5G Mobility Management-Idle (5GMM-IDLE) or 5G Mobility Management-Connected (5GMM-CONNECTED), but the current area cannot obtain services.

Related technologies are currently being studied: when the relay UE is in Mobility Restrictions (Mobility Restrictions), the relay UE may be able to provide services for the remote UE, but it can only provide emergency services or high-priority services, or provide all services. However, when the relay UE is in the Non-Allowed Area, how the relay UE enters the connected state when it needs to provide relay services is an urgent problem to be solved.

3. About suitable cells

A suitable cell can be understood as a cell that satisfies the cell selection criteria, that is, a suitable cell is a cell where a relay UE can reside.

The relay UE in a suitable cell can provide relay services for remote UEs, but how the relay UE in a non-suitable cell enters the connection state when it needs to provide relay services is an urgent problem to be solved.
