1  Scopep. 6

The present document provides the stage 3 specification of the Nu reference point. The functional requirements and the stage 2 specifications of the Nu reference point are specified in TS 23.682. The Nu reference point lies between the Packet Flow Description Function (PFDF) and the Service Capability Exposure Function (SCEF).
