5.15.11.2.3 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 NSAC architecture and NSACFs deployed in a Centralized NSAC architecture is as follows

  • If multiple NSAC service areas are deployed in a PLMN, the SMF provides the NSAC Service Area Identifier to the centralized NSACF. The centralized NSACF also stores the NSAC Service Area Identifier of the SMF the PDU session is established on.
