Abstract
A system for communicating data via a cellular network control channel of a cellular mobile radiotelephone system. The system includes a mobile switching center operable for receiving a registration signal from a registering cellular communications device. The registration signal includes identification information associated with the registering cellular communications device and a predefined data field containing data. The mobile switching center detects the presence of the identification information in the registration signal. In response to the identification information, the mobile switching center determines whether the registering cellular communications device is a member of a predetermined class of cellular sources, such as a class known as "roamer" units. If the registering cellular communications device is a member of a predetermined class of cellular sources, the mobile switching center extracts the data from the predefined data field and transmits the data to a data collection system, typically via a communication link between the mobile switching center and the data collection system. In turn, the data collection system can send the extracted data to a data processing…
