Service area restrictions are applicable only to 3GPP access and to wireline access.
Clause 5.3.5.2 applies when the UE accesses 5GCN over 3GPP access.
Clause 5.3.5.3 applies when the 5G-RG or the W-AGF acting on behalf of an FN-CRG (or on behalf of the N5GC device) access 5GCN over wireline access.
NOTE: Service area restrictions are not applicable for the W-AGF acting on behalf of the FN-BRG.
The network can optionally convey operator policy for service area restriction exemptions for UEs configured for high priority access in selected PLMN or SNPN using the HPASE bit of the Feature authorization indication IE in the REGISTRATION ACCEPT message or the HPASE bit in the Feature authorization indication IE in the CONFIGURATION UPDATE COMMAND message, if the UE supports HPAEP.
