NEF deep dive: capabilities, API groups, traffic influence

NEF Core Capabilities

The NEF provides far more than simple API proxying. Its core capabilities include traffic influence, where it instructs the PCF and SMF to route user traffic through specific paths or local data networks. Event exposure allows AFs to subscribe to UE mobility events, session state changes, and network analytics from NWDAF. Parameter provisioning lets AFs configure expected UE behavior patterns like periodic communication schedules for IoT devices. The NEF also handles Application Function Influence on Traffic Routing, enabling edge computing scenarios where traffic must be steered to the…
