Upon receiving an identification signal from an indoor base station (30), a mobile terminal (10) makes a location registration request to a controller (20) through the station (30).

Upon registration of the subscriber unit with its home access network (111), the home access number is transmitted to the subscriber unit for storage there.

When the subscriber unit moves to a visited access network (113) and registers there, the subscriber unit transmits the home access number to the visited access network, which uses the home access number to contact the home access network.

In one implementation, the selection is based upon the location of the subscriber unit and upon any references specified by the subscriber unit.

The subscriber station determines if emergency broadcast information is in the control channel cycle assigned to the subscriber station and responds accordingly.

The detection of a bogus subscriber unit (B) is accomplished by recording the call origination and termination patterns associated with the subscriber number.
