An apparatus for providing IP multicast transport may include a processor and a memory. The memory may store ex&#xe9;cutable instructions that in response to ex&#xe9;cution by the processor cause the apparatus to at least perform op&#xe9;rations including receiving a key for encapsulation of multicast data at a base station, using the key to generate a response to a message indicative of a multicast connection for a particular service received from a gateway device, the base station being joined to a same multicast tree in a multicast-broadcast zone as the gateway device, and establishing the multicast connection with the gateway device via a multicast data path comprising a multicast tunnel associated with the key. Corresponding methods and computer program products are also provided.

Method, apparatus, and computer program product for providing internet protocol multicast transport

A method involves determining a first content identifier for content and determining a second content identifier for the content, wherein the first content identifier belongs to a first system layer and the second content identifier belongs to the second system layer. The method further involves requesting for delivering of the content by transmitting the first content identifier in a control message, wherein the control message belongs to a second system layer. The content is received via radio interface within a connection, wherein the connection belongs to the second layer. The second system layer is lower than the first system layer.
