The present document specifies the stage 3 protocol and data model for the Service Based Interface (SBI) of the Data Transfer Policy Control Services. It provides stage 3 protocol definitions and message flows, and specifies the APIs of the Data Transfer Policy Control Services offered by the Policy Control Function (PCF).
The 5G System stage 2 architecture is specified in TS 23.501. The stage 2 definition and related procedures for Data Transfer Policy Control Services are specified in TS 23.502 and TS 23.503.
The 5G System 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 are specified in TS 29.500 and TS 29.501.

4 Overview p. 8
The Data Transfer Policy Control Services, as defined in TS 23.502 and TS 23.503, are part of the Npcf service based interface exhibited by the Policy Control Function (PCF).
The Network Exposure Function (NEF) is the only NF service consumer of the Data Transfer Policy Control Services.
The NEF accesses the Data Transfer Policy Control Services at the PCF via the N30 Reference point. In this release, the roaming is not supported.
Figure 4-1 and Figure 4-2 depict the Data Transfer Policy Control Services related reference architecture of the PCF respectively in SBI representation and reference point representation.
