1 Scope
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.
NOTE: The call flows depicted in this Technical Specification do not cover all traffic cases.
The stage 2 definition and procedures of PCC are contained in 3GPP TS 23.502 [3] and 3GPP TS 23.503 [4]. The 5G
System Architecture is defined in 3GPP TS 23.501 [2].
Detailed stage 3 procedures are provided in 3GPP TS 29.507 [7], 3GPP TS 29.508 [8], 3GPP TS 29.512 [9],
3GPP TS 29.514 [10], 3GPP TS 29.520 [11], 3GPP TS 29.519 [12], 3GPP TS 29.521 [22], 3GPP TS 29.594 [23],
3GPP TS 29.522 [24], 3GPP TS 29.551 [25], 3GPP TS 29.525 [31] and 3GPP TS 29.554 [26].
The Technical Realization of the Service Based Architecture and the Principles and Guidelines for Services Definition
of the 5G System are specified in 3GPP TS 29.500 [5] and 3GPP TS 29.501 [6].
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.
