Defines Stage 2 architecture enhancements for 5GS to support network data analytics via NWDAF, including data collection, analytics exposure, and roaming.
This specification defines the Stage 2 architecture enhancements for the 5G System (5GS) to support network data analytics services in the 5G Core network. It introduces the Network Data Analytics Function (NWDAF) as a key component for collecting data from 5GC NFs and OAM, and providing analytics (statistical or predictive) to consumers. The document covers non-roaming and roaming architectures, NWDAF discovery and selection, and detailed procedures for analytics subscription, exposure, and notification. It is essential for enabling data-driven network optimization and automation in 5G networks.
The present document defines the Stage 2 architecture enhancements for 5G System (5GS) to support network data analytics services in 5G Core network.
