Defines Stage 2 architecture enhancements for 5GS to support network data analytics services, including NWDAF, data collection, and federated learning.
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 details the Network Data Analytics Function (NWDAF), its interfaces, and procedures for data collection from various network functions and OAM. The document covers analytics provisioning, accuracy information, machine learning model management, and federated learning techniques including Vertical Federated Learning. It is essential for enabling AI/ML-driven network optimization, predictive maintenance, and intelligent resource management 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.
