1  ScopeWord‑p. 7
The present document specifies detailed call flows of Policy and Charging Control (PCC) over the Npcf, Nsmf, Namf, Nudr, Nnef, Nchf, Nbsf and Nnwdaf service-based interfaces and their relationship with the flow level signalling in 5G system.
The stage 2 definition and procedures of PCC are contained in TS 23.502 and TS 23.503. The 5G System Architecture is defined in TS 23.501.
Detailed stage 3 procedures are provided in TS 29.507, TS 29.508, TS 29.512, TS 29.514, TS 29.520, TS 29.519, TS 29.521, TS 29.594, TS 29.522, TS 29.551, TS 29.525 and TS 29.554.
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 present specification also describes the PCC reference architectures for non-roaming and roaming scenarios in 5G system.
The present specification also describes the mapping of QoS parameters at AF, PCF and SMF.
The present specification also describes the session binding at PCF, and the QoS flow binding at SMF.
The present specification also describes the PCF addressing.
