Abstract: The present invention relates to multicast communication systems and in particular to the implementation of a random access uplink channel, which can be used, e.g., for transmission of acknowledgement messages for received data. In order to prevent frequent collisions on said channel, the transmission of acknowledgement messages is spread at least over time or, additionally, with regard to another distinguishing channel property, e.g. a RACH sub-channel or RACH-signature.

Abstract: A method and user equipment in a mobile telecommunications system for conducting a multimedia broadcast/multicast service (MBMS) session. An MBMS-uplink channel is introduced for transmitting from the user equipment, MBMS participation requests prior to the session and acknowledgment messages when MBMS messages are received. Relevant charging information is collected from the user equipment using broadcast/multicast services when an acknowledgment message is received. The telecommunication system then sends a decoding key to the user equipment for decoding at least a part of the data that is broadcast by the MBMS service.

Abstract: A radio network control node acts across an Iur interface as a drift radio network control node (262) for a user equipment unit (UE) in a communications system supporting a multimedia broadcast multicast service (MBMS). The drift radio network control node (262) maintains a first counter for counting a number of events occurring at the drift radio network control node (262). Registration of the drift radio network control node (262) with a core network node (30) is advantageously delayed until the counter has exceeded a first threshold value. In one example mode, the number of events occurring at the drift network control node (262) which is counted by the counter is a number of user equipment units for which a Iur linking procedure is performed for the MBMS session. In another example mode, the number of events occurring at the drift network control node (262) which is counted by the counter are time periods elapsed since an Iur linking procedure for the MBMS session has been performed for a predetermined user equipment unit.
