Abstract

A method and apparatus for locating a mobile radio communications transceiver in a cellular-telephone or cell-like communications system uses a simplified system for passive monitoring of the signals emitted by the transceiver. A single base station can determine a line of bearing to the remote transceiver. This line of bearing is then combined with collateral, position-sensitive information to determine the likely location of the transceiver. The present invention has particular applicability to roadway transportation in that it facilitates enhanced emergency (9-1-1) services and roadside assistance in response to calls for assistance, and it permits the passive monitoring of traffic flow.
