Abstract
A system for communicating data via a cellular network control channel of a cellular mobile radiotelephone system (CMR). A data message system for communicating data collected from remote data sources includes sets of reporting devices, at least one mobile switching center (MSC) of a CMR system, and a data collection system connected to said MSC via a first communications link. Each recording device monitors a remote data source to obtain selected data and thereafter transmits a data message containing the selected data. The data collection system stores the data messages and processes the selected data. The data message system is equipped to process data messages of varying lengths, through the use of an expandable data message structure. A paging acknowledgment system is also provided for communicating both (1) paging messages and (2) acknowledgment messages to confirm reception of the paging messages. A communications system transmits data messages corresponding to the paging message via a communications link. The data message contains the type of data that is normally supplied with a conventional paging message and an acknowledgment code that uniquely identifies said data message. The communications system confirms reception of the data message by comparing the acknowledgment code of the acknowledgment message to the acknowledgment codes associated with the paging messages. The communications system is equipped to process acknowledgment messages of varying lengths, through the use of an expandable data message structure.
