A method for re-establishing communication between a base station ( ) that transmits on a forward channel, and a subscriber unit ( ) that has temporarily lost the forward channel, uses the concept of a re-registration interval. The base station ( ) transmits, to subscriber units ( ) in its area, a signal indicating the duration of a re-registration interval. A subscriber unit that has temporarily lost the forward channel determines whether the duration of such loss exceeds the re-registration interval. If the interval is exceeded, the subscriber unit sends a re-registration signal to the base station on a reverse channel. A selective call transceiver ( ) is programmed to operate as a subscriber unit that uses the re-registration interval.

Selective call transceiver and method of re-registering same

A method for re-establishing communication between a base station (102) that transmits on a forward channel, and a subscriber unit (108) that has temporarily lost the forward channel, uses the concept of a re-registration interval. The base station (102) transmits, to subscriber units (106, 108) in its area, a signal indicating the duration of a re-registration interval. A subscriber unit that has temporarily lost the forward channel determines whether the duration of such loss exceeds the re-registration interval. If the interval is exceeded, the subscriber unit sends a re-registration signal to the base station on a reverse channel. A selective call transceiver (400) is programmed to operate as a subscriber unit that uses the re-registration interval.

A method and apparatus controls zone registrations in a radio communication system providing radio coverage to a portable subscriber unit (122, 1200) within a plurality of zones (402). A fixed portion (102) of the radio communication system cooperates with the portable subscriber unit (122, 1200) to adjust at least one registration variable in a memory of the portable subscriber unit (122, 1200) for moderating the zone registrations. The portable subscriber unit (122, 1200) then moderates the zone registrations to a limited number in accordance with the at least one registration variable.
