4 Overview p. 9
In the frame of supporting Multicast/Broadcast Services (MBS), the Policy Control Function (PCF) provides services to NF service consumers (e.g. MB-SMF) via the Npcf Service Based Interface. The PCF supports for this purpose the functionalities defined in TS 23.247, i.e. MBS related Policy and Charging Control procedures.
Figure 4-1 and Figure 4-2 depict the Multicast/Broadcast related reference architecture of the PCF respectively in SBI representation and reference point representation.
