The present document specifies the stage 3 protocol and data model for the Nmbsf Service Based Interface. It provides stage 3 protocol definitions and message flows, and specifies the API for each service offered by the MBSF.
The 5G System stage 2 architecture and procedures are specified in TS 23.501 and TS 23.502. The stage 2 architecture and procedures for 5G Multicast/Broadcast Services are specified in TS 23.247 and TS 26.502.
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. 11
In the frame of Multicast/Broadcast Services (MBS), the Multicast/Broadcast Service Function (MBSF) provides services to NF service consumers (e.g. AF, NEF) via the Nmbsf service based interface. The MBSF supports for this purpose the functionalities defined in TS 26.502 and TS 23.247, i.e. service level functionalities to support MBS and the control of the MBSTF, when used.
Figure 4-1 and Figure 4-2 depict the Multicast/Broadcast related reference architecture of the MBSF respectively in SBI representation and reference point representation.
