5.15.11.1.3 Centralized NSAC architecture
Taught in 17. One network, many networks (The 5G system architecture, in depth), 6. One network behaving like several (The 5G system architecture, overview).
The main differences between the NSACFs deployed in a non-Hierarchical architecture and NSACFs deployed in a Centralized NSAC architecture is as follows:
- If multiple NSAC service areas are deployed in PLMN, the AMF provides the NSAC Service Area Identifier information to the centralized NSACF. The centralized NSACF also stores the NSAC Service Area Identifier of the AMF the UE is registered with.
