Patent abstract
The invention relates to a method, network node, router, serving node and system for performing multicast data delivery in a mobile telecommunication network. The basic idea is to provide a management of the multicast groups within a mobile telecommunication network. In particular this means to synchronize the multicast group information between routers, like for example the GGSNs. This avoids duplicate multicast data delivery tree allocation for the same multicast group.
