Abstract
There is disclosed for use in a narrowband wireless messaging network, a subscriber communication unit that uses a miscellaneous ALOHA message to transmit predefined messages and/or formatted telemetry data to a base station. The subscriber communication unit comprises a transceiver for receiving messages from the base station in a forward channel and transmitting messages to the base station in a reverse channel. The reverse channel is divided into a plurality of scheduled transmission time slots and a plurality of unscheduled transmission time slots of the ALOHA type. A message controller receives input data generated by the subscriber communication unit and translates the input data into a reverse channel message capable of being transmitted in an available unscheduled time slot, such as a miscellaneous ALOHA message time slot.
