Abstract
A selective call transceiver (122) includes a receiver (303) and a transmitter (301) coupled to a processor (308) serving as a decoder and an encoder. The processor is programmed to receive an input requiring the selective call receiver to request a reserved time assignment from a system controller (11) for a transmission of unscheduled information, the request to be sent on a reverse or inbound channel. The processor further determines whether a scheduled transmission is pending for transmission on the reverse channel during a scheduled time slot and sends the unscheduled information and an indicia of the scheduled transmission during the scheduled time slot if there is a scheduled transmission pending.
