First Claim
1. In or for a cellular mobile radiotelephone (CMR) system having an array of cells for communicating with cellular mobile radiotelephones within coverage areas of said array of cells, a data message system for communicating selected data collected from a plurality of remote data sources, said data message system comprising:
- a plurality of data reporting devices, each of said data reporting devices operative for monitoring a corresponding one of said remote data sources to obtain said selected data and for transmitting a data message containing said selected data;
a mobile switching center (MSC) for receiving said data message via a cellular network control channel from each of said data reporting devices operating within said coverage areas of said array of cells; and
a data collection system for collecting said selected data in response to receiving said data message from said MSC via a first communications link, said data message formatted as a call origination signal transmitted by one of the cellular mobile radiotelephones when said cellular mobile radiotelephone originates a cellular telephone call for communication via said CMR system;
wherein said call origination signal comprises a mobile telephone number data field and an expandable electronic serial number (ESN) data field, thereby enabling the data message system to communicate data messages comprising selected data of varying sizes.

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.

17. In or for a cellular mobile radiotelephone system (CMR) having an array of cells for communicating with cellular mobile radiotelephones within coverage areas of said array of cells, a paging acknowledgment system for communicating paging messages and acknowledgments to confirm reception of said paging messages, said paging acknowledgment system comprising:
-
a communications system, responsive to said paging messages, for preparing data messages corresponding to said paging messages and transmitting said data messages via a radiopaging communications path; a plurality of remote communications devices for receiving said data messages via said radiopaging communications path, each of said data messages containing an address that uniquely identifies one of said remote communications devices, each of said remote communications devices responsive to a selected one of said data messages containing its associated address for transmitting via a cellular network control channel of said CMR system an acknowledgment message that confirms reception of said selected data message, said acknowledgment message formatted to correspond to a call origination signal transmitted by one of the cellular mobile radiotelephones when said cellular mobile radiotelephone originates a cellular telephone call for communication via said CMR system; at least one mobile switching center (MSC) for receiving said acknowledgment message via said cellular network control channel from each of said remote communications devices; and said communications system further operative to receive said acknowledgment message from said MSC via a first communications link and to process said acknowledgment message to determine whether said acknowledgment message corresponds to a particular one of said data messages; wherein said call origination signal comprises a mobile telephone number data field and an expandable electronic serial number (ESN) data field, thereby enabling the paging acknowledgment system to communicate acknowledgment messages comprising operation data of varying sizes. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
