Abstract: A communication system is described in which an MBMS service is provided by unicast or broadcast/multicast communication in dependence on whether the number of mobile communication devices indicating an interest in receiving the service is below or above a broadcast threshold. An improved procedure for counting the number of mobile communication devices interested in receiving the MBMS service is also disclosed.

Abstract: A system is disclosed in which a base station initiates a handover of a mobile relay node associated with the base station. The base station obtains information that identifies at least one further base station, and that indicates that the at least one further base station is capable of providing donor services to the mobile relay node. When the base station determines that the mobile relay node requires handover, it selects, from at least one cell of the at least one further base station identified by the obtained information, a target cell for handover of the mobile relay node, and performs handover of the mobile relay node to the selected target cell.
