IMPROVED RECOURCE UTILIZATION FOR MULTIMEDIA BROADCAST MULTICAST SERVICES (MBMS)

摘要

A multimedia broadcast multicast type service (MBMS) is offered to mobile subscribers. A RAN node communicates with one or more radio base stations that transmit and receive information with mobile subscriber terminals, some of which subscribe to the MBMS. The RAN node communicates with multiple core network packet data nodes that receive MBMS data for delivery to the RAN node. One of the multiple core network packet data nodes is selected to provide the MBMS data associated with the MBMS to the RAN node. The others are instructed not to provide the MBMS data, but they still perform other MBMS support functions for their mobile terminals such as MBMS charging, etc.
