Abstract (en)

[origin: WO0117134A1] There is disclosed, for use in a narrowband wireless messaging network (100), a subscriber communication unit (124) that uses a miscellaneous ALOHA message to transmit predefined messages and/or formatted telemetry data to a base tension. The subscriber communication unit (124) comprises a transceiver (225) for receiving messages from the base station (112) in a forward channel and transmitting messages to the base station (112) 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 (210) receives input data generated by the subscriber communication unit (124) 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.
