ABSTRACT:
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.
