Abstract
A system and method are shown for registering a subscriber unit (10) in an integrated communication system having a number of subsystems (30, 50) that are capable of operating independently. The subscriber unit (10) stores in a memory (77) a list of outbound subsystems ordered according to the subscriber unit's preference for using the subsystem as a outbound home subsystem to which the subscriber unit registers. An inbound preferred home subsystem list is also stored in the memory (77). In order to register to the integrated system, the subscriber unit identifies the most preferred outbound subsystem that covers the current location of the subscriber unit as its outbound home subsystem. If the outbound home subsystem is a two-way subsystem having an inbound channel accessible by the subscriber unit, the subscriber unit uses the inbound channel of the outbound home subsystem to communicate the registration information to the integrated system. If the outbound home subsystem is a one-way subsystem, the subscriber unit utilizes the inbound preferred home subsystem list to identify the most preferred inbound subsystem covering the current location of the subscriber for use in communicating the new registration information to the integrated subsystem.
