Abstract
Multicasting in Multimedia Broadcast Multicast Service (MBMS) nodes and the respective nodes. The method in a node configured as an MBMS gateway includes, in response to receipt of a session start request message for a multicast session, allocating a transport network IPv4 multicast address and a transport network IPv6 multicast address for the session, and generating another session start request message and transmitting it to a node configured as a Mobility Management Element (MME). The session start request message includes a first pair of the allocated transport network IPv4 multicast address and an IPv4 multicast source address, and a second pair of the allocated transport network IPv6 multicast address and an IPv6 multicast source address. In response to receipt of MBMS data from a node configured as a Broadcast-Multicast Service Center (BM-SC), the MBMS data is sent using at least one of the first and second pair of addresses.
