MBMS Gateway


The MBMS gateway is the source of a broadcast/multicast flow between the core network and the eNBs within the cell sites involved in the MBMS (Multimedia Broadcast Multicast Service) service. The MBMS Gateway uses SSM (Source-Specific Multicast) techniques to simultaneously deliver the data stream to multiple cell sites. The MBMS Gateway may be a standalone network element or physically co-located with the combined S-GW/P-GW (Serving Gateway/PDN Gateway) or the BMSC (Broadcast Multicast Service Center).
