SYSTEM AND METHOD FOR COMMUNICATING THE LOCATION OF AN EMERGENCY CALLER THROUGH A TELEPHONE NETWORK TO A CONTROL STATION

摘要

A system and a method for communicating the location of an emergency caller through a telephone network use a mobile telephone set (1) having a location detection unit (12). The position data is translated into a stream of audio tones to be transmitted while the call connection is in progress. According to an alternative solution the position data is translated into one of a multitude of assigned telephone numbers to be transmitted during the setup phase of the call connection. The telephone numbers can be combined with the ID of the cell tower (21) the cellular phone (1) is communicating with. The invention combines well established techniques resulting in a cost efficient cellular emergency call service.
