Identifying and registering the location of a mobile data reporting device operating within the coverage areas of a cellular mobile radiotelephone (CMR) system. The mobile data reporting device travels freely between CMR systems and is operative to communicate selected data collected from data sources to a data collection system via control channels of the CMR system. The location registration system enables the data collection system to transmit a data message to the mobile data reporting device via the control channels of the particular CMR system within the coverage areas of which the mobile data reporting device resides. Each CMR system transmits a beacon page that distinguishes the CMR system from adjacent CMR systems. When the mobile data reporting device receives a beacon page that is different from a previously received beacon page, the mobile data reporting device generates a beacon-responsive signal. The beacon-responsive signal is transmitted to the data collection system and enables the data collection system to determine the location of the mobile data recording device. Because the particular CMR system is identified, the data collection system can transmit a data message to the mobile data reporting device without flood paging all of the CMR systems in which the mobile data reporting device might be located.

Method and system for registering the location of a mobile cellular communications device

An asymmetrical data communications system (ADCS) provides point-to-multipoint television programming including conventional television programming, near video-on-demand (NVoD) or video-on-demand (VoD), and the full variety of available programming, via a compressed, digitized UHF transmission. A program subsystem of the ADCS receives programming from content providers and processes the received signals for channel and VoD or NVoD service, then sends the aggregated signal to a transmission subsystem that modulates, channelizes, amplifies, filters and broadcasts the digital UHF signals over the air. Subscribing viewers are equipped with an intelligent control box (ICB) suitably configured to receive, demodulate, and decode the digital UHF broadcast and to transmit the resulting signal to one or more display or other terminal devices. The ICB further provides a matrix switch or gateway for receiving signals over any available transmission path. In addition to the ICBs of the subscribing viewers, a return path subsystem of the ADCS system includes a session control and administrative facility to which the ICBs are linked via the public switched telephone network or suitable wireless alternative so that transaction and viewing data can be received from the subscribing viewers. The return path subsystem, in turn, is linked to the program subsystem in order to route to that subsystem any information necessary or useful for providing programming.
