The present document specifies the stage 3 protocol and data model for the Application Function ProSe Service of the 5G System. It provides stage 3 protocol definitions and message flows, and specifies the API for the Naf_ProSe service.
The 5G System stage 2 architecture and procedures are specified in TS 23.501, TS 23.502 and TS 23.304.
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.
The Application Function ProSe Service is provided by the Application Function (AF). This service supports 5G ProSe Direct Discovery authorization.

4 Overview p. 8
The Application Function ProSe (Naf_ProSe ) Service, as defined in clause 7.2.2 of TS 23.304, is provided by the Application Function (AF) which owns the functionality of ProSe Application Server.
Figure 4-1 and Figure 4-2 provide the reference architecture (in service based interface representation and reference point representation), with focus on the ProSe Service of the Application Function.
The Naf_ProSe Service is part of the Naf service-based interface exhibited by the AF. The service is provided by the AF and consumed by NF service consumers (e.g. 5G DDNMF), as shown in Figure 4-1 for the SBI representation and Figure 4-2 for the reference point model.
