4.28.1 General

A 5GS can support an MWAB-UE and a UE accessing via an MWAB (see clause 5.49 of 3GPP TS 23.501 [8]). This clause describes NAS-specific aspects of 5GS features to support authorization of the MWAB-UE, and control of the UE access via the MWAB.

The MWAB-UE is served by a BH PLMN or BH SNPN. The MWAB-UE establishes one or more PDU sessions for MWAB using UE local configuration and URSP rules of the MWAB-UE according to 3GPP TS 24.526 [19].

NOTE 1: The one or more PDU sessions for MWAB enable the MWAB to communicate with the core network of the MWAB broadcasted PLMN or MWAB broadcasted SNPN. Some of the one or more PDU sessions for MWAB can carry communication associated with emergency services provided to a UE served by the MWAB.

NOTE 2: The one or more PDU sessions for MWAB are associated with an S-NSSAI for MWAB.

BH PLMN or BH SNPN can be the same as or different from the MWAB broadcasted PLMN or MWAB broadcasted SNPN. If the MWAB is configured to support emergency services for served UEs, the BH PLMN or BH SNPN is in the same country as the MWAB broadcasted PLMN or MWAB broadcasted SNPN.
