1  ScopeWord‑p. 11
The present document provides the stage 3 specification of the Session Management Policy Control Service of 5G system. The stage 2 definition and related procedures of the Session Management Policy Control Service are contained in TS 23.502 and TS 23.503. The 5G System Architecture is defined in TS 23.501.
Stage 3 call flows are provided in TS 29.513.
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 Policy Control Function with session related policies provides the Session Management Policy Control Service to the NF consumers (i.e. Session Management Function).
