Abstract

A method and apparatus of transmitting subject status information, such as the status and location of a parolee or individual under house arrest, to a central monitoring station (CMS) operated by, for example, a parole staff or correctional facility. The subject status information is transmitted by a band or collar attached to, for example, the leg or wrist of the subject. A cellular radio communicator receives, encodes and transmits the subject status information over the control channel of a cellular radio communications network as control signals, bypassing the voice channels, to a mobile switching center (MSC) of the cellular radio communications network. The MSC decodes and forwards the subject status information over the public switched telephone network (PSTN) to the CMS. Optionally, the CMS may send a command to the communicator over the same data paths, i.e., the PSTN to the MSC, then over the control channel, formatted as a control signal, to the cellular radio communications network communicator. The communicator may integrate a paging receiver, or a satellite receiver, or other wireless receiver for receiving commands out of band, i.e., by way of communication networks other than the cellular radio communications network. The method and apparatus may also be utilized to track to position of more than one subject relative to other subjects or objects.
