Abstract
The present invention allows for a communication device (136) which roams within a communication system (100), the ability of maintaining in contact with other communication units, even while the unit is away from its home sub-system. Communication system (100) comprises a wide area paging system which includes a wide area paging controller (184) which controls at least one local area paging controller (108, 182 and 156). When a communication unit is away from its home system, the home system sends out a page via the wide area paging system in order to locate the communication unit and direct the unit to a local sub-system which the unit can use to communicate with the calling unit.
