MBMS defined in 3GPP as MBMS defined in 3GPP as “a “a point-to-multipoint point-to-multipoint (PTM) downlink bearer service for IP data in the PS (PTM) downlink bearer service for IP data in the PS domain”domain”

ObjectivesObjectives Offer high speed Data Rates up to 256 kbit/sOffer high speed Data Rates up to 256 kbit/s Enhance UMTS by a more efficient Multicast and Broadcast Enhance UMTS by a more efficient Multicast and Broadcast
