Abstract: A communication system is disclosed in which an anchor base station configures a RAN based paging area for a communication device. When the anchor base station determines that it is necessary to update the RAN based paging area, it seeks to inform the communication device indicating that the RAN paging area for the communication device needs to be updated at the communication device, and subsequently, the base station may broadcast system information comprising information identifying a change to the paging area (e.g. a removal of a cell). The broadcasting of system information may also be carried out in other cells of the paging area.

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.
