1. A method for facilitating distribution of multimedia broadcast multicast services (MBMS) in a telecommunications network, comprising the steps of:

  • receiving an MBSM session start message from a broadcast/multicast service center;

    sending control traffic on a control network;

    sending as control traffic to a serving node an MBMS session start request message and including a common tunnel end-point identifier (cTEID) in the MBMS session start request message;

    receiving information from the serving node indicating the acceptance of using IP multicast; and

    sending media content on an IP multicast backbone to hosts that have joined the multicast group using the cTEID.
