Abstract
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.
