4.28.2 Authorization of MWAB-UE

A UE is authorized to act as the MWAB-UE, if the UE is allowed to establish the one or more PDU sessions for MWAB, otherwise the UE is not authorized to act as the MWAB-UE.

NOTE 1: Whether the UE is allowed to establish the one or more PDU sessions for MWAB and thus is authorized to act as the MWAB-UE can be influenced e.g. by LADN service area information, if DNN of a PDU session for MWAB is LADN, S-NSSAI time validity information, S-NSSAI location validity information, or DNN based or S-NSSAI based congestion control.

NOTE 2: If a dedicated S-NSSAI for MWAB is not included in the allowed NSSAI provided in the generic UE configuration update or the registration procedure for mobility registration update, then the AMF serving MWAB-UE can delay the notification of the SMF associated with a PDU session associated with the S-NSSAI and DNN combination for MWAB to initiate the network-requested PDU session release procedure (see clause 5.49.3 of 3GPP TS 23.501 [8]) for a locally configured time.
