5.1.3.2.3.1 General

In the following clauses, the possible 5GMM sublayer states of the network are described and shown in figure 5.1.3.2.3.1.1.

NOTE: Not all possible transitions are shown in this figure.

5.1.3.2.3.2 5GMM-DEREGISTERED

In the state 5GMM-DEREGISTERED, no 5GMM context has been established or the 5GMM context is marked as deregistered. The UE is deregistered. The network may answer to an initial registration procedure initiated by the UE. The network may also answer to a de-registration procedure initiated by the UE.

5.1.3.2.3.3 5GMM-COMMON-PROCEDURE-INITIATED

The network enters the state 5GMM-COMMON-PROCEDURE-INITIATED, after it has started a common 5GMM procedure and is waiting for a response from the UE.

5.1.3.2.3.4 5GMM-REGISTERED

In the state 5GMM-REGISTERED, a 5GMM context has been established. Additionally, one or more PDU session(s) may be established at the network.

5.1.3.2.3.5 5GMM-DEREGISTERED-INITIATED

The network enters the state 5GMM-DEREGISTERED-INITIATED after it has started a de-registration procedure and is waiting for a response from the UE.
