A network element provides broadcast/multicast support. The network element is configured to be operably connected with at least one stream source and with a terminal. The network element is further configured to process a multicast stream over a logical connection which has been dedicated between the stream source and the network element as one of a plurality of network elements participating in the logical connection. In addition, the network element is configured to map the logical connection into a broadcast/multicast radio channel which corresponds to the operable connection to the terminal.
