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.

System and method for transmitting subscriber data in a narrowband advanced messaging system using unscheduled message time slots

There is disclosed an application controller for use with a two-way wireless messaging system. The application controller is distributed, at least in part, among a plurality communication units associated with the two-way wireless messaging system. The application controller is capable of controlling cooperative communication among ones of the communication units in accordance with a prescribed application task, and comprises a data repository, first and second communication controllers, and an operations controller. The data repository maintains at least one subscriber profile. The first communication unit controller senses change in a characteristic monitored at a first communication unit, wherein the monitored characteristic is evaluated in accordance with the prescribed application task, and, in response thereto, automatically causes the first communication unit to transmit a first data signal. The operations controller analyzes the first data signal in accordance with the prescribed application task using the at least one subscriber profile, and, in response thereto, causes a second data signal to be communicated automatically to at least a second communication unit. The second communication unit controller automatically analyzes the second data signal at the second communication unit, and, in response thereto, transmits an acknowledgment signal to at least said first communication unit.

System and method for controlling an end-user application among a plurality of communication units in a wireless messaging network

A reverse channel power controller for use in a narrowband wireless messaging network containing a plurality of base stations that communicate with subscriber communication devices. The reverse channel power controller controls the transmission power of the subscriber communication devices. The reverse channel power controller contains: 1) a reverse channel traffic determination circuit for determining a level of reverse channel traffic received by a selected one of the plurality of base stations; and 2) a communication controller for transmitting to the selected subscriber communication device a power control command capable of causing the selected subscriber communication device to adjust a power level of a reverse channel signal transmitted by the selected subscriber communication device.
