3GPP 23.501 v20.2.0 — the document's own text
5.49.6.1 General
Taught in 26. Relays, satellites, femtos and shared networks (The 5G system architecture, in depth).
Control of UE access to MWAB is supported. If the MWAB-gNB is serving a PNI-NPN, the CAG mechanism described in clause 5.49.6.2 is used. If the MWAB-gNB is serving an SNPN, the SNPN control mechanism described in clause 5.49.6.3 is used.
The MWAB-gNB and the 5GC can reuse other existing mechanisms e.g. forbidden Tracking Area, UAC, to manage the UE's access to an MWAB-gNB cell.
NOTE: MWAB-UE's access to the network is controlled with mechanisms defined in clause 5.2 for PLMN and clauses 5.30.2 and 5.30.3 for SNPN/PNI-NPN, based on subscription data of the MWAB-UE. It is not addressed in this clause.
