NWDAF
Network Data Analytics Function
The NWDAF is responsible for providing network analysis information upon request from network functions. For example, a network function may request specific analysis information on the load level of a particular network slice. Alternatively, the network function can use the subscribe service to ensure that it is notified by the NWDAF if the load level of a network slice changes or reaches a specific threshold. Other analytics capabilities for the NWDAF include Observed Service Experience, NF Load, Network Performance, UE Related, User Data Congestion, QoS Sustainability, Dispersion, WLAN Performance, Session Management Congestion Control Experience, Redundant Transmission Experience, DN Performance
