ABSTRACT:
The invention provides a solution for performing multicast within a telecommunication network. The basic idea is to introduce multicast transmission for parts of a network that is basically point-to-point oriented. This is done by creating transport multicast groups TLMG to transport data between network entities. The idea is to have a TLMG going to a node being close to the user. In one embodiment of the invention one TLMG is established between the SGSNs and RNCs and a second one between the GGSN and SGSNs. From the RNC the data is sent via a radio bearer to a user.
