context: Figure 5.2.2.2.3.1 shows the charging interaction during the BM-SC initiated MBMS Deregistration procedure for a multicast bearer for an already started session. Figure 5.2.2.2.3.1: Rf interaction during BM-SC initiated MBMS Deregistration procedure for a multicast bearer 1) The BM-SC performs the MBMS Deregistration procedure as described in TS 23.246 [200]. The BM-SC sends a De-registration Request message to all GGSNs contained in the "list of downstream nodes" parameter of the corresponding MBMS Bearer Context to indicate the session is terminated. 2a) On receiving an MBMS Deregistration Response from the GG, the BM-SC sends an Charging Data Request [Stop]. 2b) The remainder of the MBMS Deregistration procedure occurs in parallel with the Charging Data Request procedure in 2a. The full details of the MBMS Deregistration procedure for the multicast bearer are described in TS 23.246 [200].
description: The Broadcast Multicast - Service Centre (BM-SC) is a network function responsible for managing broadcast and multicast services within the telecommunications network. It plays a crucial role in initiating MBMS deregistration procedures, handling session management, and interacting with other network functions such as GGSNs.
explanation: BM-SC is classified as a Network Function based on its role in controlling and managing broadcast and multicast services, as well as its interaction with other network elements like GGSNs during the MBMS deregistration procedure, as described in the provided context.
