Efficient MBMS backbone distribution using one tunnel approach
First Claim
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.

Abstract
The present invention relates to a method, signal and devices for facilitating distribution of multimedia broadcast multicast services, i.e. MBMS, in a telecommunications network by 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, i.e. common TEID, 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 common TEID. If any part of the communication network does not accept the IP multicast backbone as distribution method tunnels will be used between the gateway and serving node and between the serving node and control node.

5. A telecommunication infrastructure network for facilitating distribution of multimedia broadcast multicast services (MBMS), comprising:
-
a broadcast/multicast service node (BM-SC); a gateway node; at least one serving node; and at least one control node; wherein the BM-SC is connected to the gateway node which in turn is connected to the serving node via two interfaces, a control interface and a backbone interface, the control node is in turn connected to the serving node and/or the gateway node, the gateway node is configured for; receiving an MBSM session start message from the broadcast/multicast service center; sending control traffic on the control interface; sending as control traffic to the 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.

6. A method for facilitating distribution of multimedia broadcast multicast services (MBMS) in a telecommunication network, comprising the steps of:
-
receiving in a gateway node an MBSM session start message from a broadcast/multicast service center (BM-SC); sending control traffic on a control network; sending as control traffic from the gateway node to a serving node an MBMS session start request message and including a common tunnel end-point identifier (common TEID) 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 common TEID. - View Dependent Claims (7, 8, 9, 10, 11)
