5.4.13.4 Paging
Taught in 9. Registration, reachability and paging (The 5G system architecture, in depth), 10. Radio, Wi-Fi, cable — every way in (The 5G system architecture, in depth).
In the case of NR satellite access that provides discontinuous network coverage, AMF may utilize sub-area paging as described in clause 4.2.3.3 of TS 23.502 [3] (e.g. first page in the last known cell-id or TA and retransmission in all registered TAs). The AMF may utilize the location information as received at or before the AN release due to the discontinuous coverage for paging optimisation.
The AMF may e.g. receive UE location from NG-RAN during the Registration procedure e.g. triggered for Mobility Management and Power Saving Optimization for discontinuous network coverage as described in clause 5.4.13.1, or the AMF may request NG-RAN location reporting when the UE is in CM-CONNECTED state as described in clause 5.4.7.
