ETSI ETSI TS 129 513 V15.0.0 (2018-06)63GPP TS 29.513 version 15.0.0 Release 151 Scope The present document specifies detailed call flows of Policy and Charging Control (PCC) over the Npcf, Nsmf, Namf, Nudr, Nnef and Nnwdaf ser
31、vice-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 A
32、rchitecture 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 and 3GPP TS 29.554 26. The
33、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
34、 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. 2 References The following documen
