Content for TS 29.551 Word version: 18.5.0
1 Scope p. 5
The present document provides the stage 3 specification of the PFD Management Service of the 5G system.
The stage 2 definition and related procedures of the PFD Management Service are contained in TS 23.502 and TS 23.503. The 5G System Architecture is defined in TS 23.501.
The Technical Realization of the Service Based Architecture and the Principles and Guidelines for Services Definition of the 5G System are specified in TS 29.500 and TS 29.501.
The Packet Flow Description Function (PFDF) provides the PFD Management Service to NF service consumers (e.g. Session Management Function). The PFDF is functionality within the NEF.
