The present document defines the Stage 2 architecture enhancements for 5G System (5GS) to support network data analytics services in 5G Core network. The NWDAF interacts with different entities for different purposes:
  • Data collection based on event subscription, provided by AMF, SMF, PCF, UDM, AF (directly or via NEF), and OAM;
  • Retrieval of information from data repositories (e.g. UDR via UDM for subscriber-related information);
  • Retrieval of information about NFs (e.g. NRF for NF-related information, and NSSF for slice-related information);
  • On demand provision of analytics to consumers, as indicated in clause 6.
