Abstract
Abstract Methods and apparatus are provided for communicating data via a cellular network control channel of a cellular mobile radiotelephone system (CMR) data. A data message system for communicating data sources includes sets 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 MSC receives data messages via the cellular network control channel from reporting devices operating within coverage areas of the array of cells and forwards the data messages via the first communications link to the data collection system. In response, the data collection system stores the data messages and processes the selected data.
