Expanding the data carrying capacity of a forward control channel of a cellular mobile radiotelephone (CMR) system. By utilizing data fields that would otherwise be unused in a conventional data message system, an operation identifier can be transmitted to a data reporting device. The forward control channel carries control messages which are capable of causing cellular devices to perform certain communications functions. An Order Code data field within the control message defines the functionality of the message. By utilizing the Order Code data fields to invoke the message waiting functionality of the control message, and replacing the message waiting data with an operation identifier, the data carrying capacity of the forward control channel is increased. An external device connected to the data reporting device can be caused to perform an operation defined by the operation identifier. The operation identifier can define an operation specified from a list of available operations. For cellular communications devices that are responsive to more than one mobile identification number (MIN), the range of operations that can be processed by a control unit is greatly expanded.
In or for a cellular mobile radiotelephone (CMR) system having an array of cells for communicating with cellular mobile radiotelephones within coverage areas of the array of cells, a data message system for communicating a control message, comprising:
In or for a cellular mobile radiotelephone (CMR) system having an array of cells for communicating with cellular mobile radiotelephones within coverage areas of the array of cells, a data message system for communicating an operation identifier defining an operation to be performed by a plurality of external devices, the data message system comprising:
In or for a cellular mobile radiotelephone (CMR) system having an array of cells for communicating with cellular mobile radiotelephones within coverage areas of the array of cells, a mobile switching center (MSC) for communicating a control message via a forward control channel, and a plurality of data reporting devices for controlling a plurality of external devices, a method for communicating within the control message an operation identifier to be performed by an external device, the method comprising the steps of:
