Abstract
For transmission of multicast data in a cellular network, a gateway () allocates a set of multicast sessions () to a single Internet Protocol Multicast group (). For each of the multicast sessions (), the gateway indicates an Internet Protocol Multicast address of the Internet Protocol Multicast group to one or more radio access network nodes () of the cellular network. For each of the multicast sessions (), the gateway () indicates a different identifier to the radio access network nodes (), e.g., in the form of a Tunnel Endpoint Identifier. The gateway () sends multicast data of the multicast sessions () in one or more Internet Protocol Multicast data packets addressed to the Internet Protocol Multicast address of the Internet Protocol Multicast group. The multicast data of each of the multicast sessions () include the respective identifier to allow identification of the multicast session () at the radio access network node ().
