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 3GPP TS 23.247 [14], i.e. MBS related Policy and Charging Control procedures.

Figures°4-1 and 4.2 depict the Multicast/Broadcast related reference architecture of the PCF respectively in SBI representation and reference point representation.
