US Patent 7996553 Multi-user streaming

The invention provides a solution for performing multicast for streaming transmission in a telecommunication system. An intermediate node is proposed which is able to connect the functionality of a broadcast/multicast server and of a streaming node. Further the intermediate node is responsible for the establishment of a bearer for multicast transmission. The establishment of a session is done by means of a translation the on-demand single-use signalling into multi-user push signalling. Furthermore an adaptation of the streaming flow for a whole multicast group or for individual subgroups of a multicast group is performed.
