Abstract
A mobile telephone is provided with an emergency beacon. When the telephone's user dials an emergency number, such as 9-1-1, the telephone detects that an emergency number has been dialed, and it activates the beacon. The beacon may be a radio beacon, and, if the telephone is GPS-equipped, the radio beacon may send out the mobile telephone's location. Safety personnel can locate the caller by following the beacon to the caller. Other optional features include an audio emergency beacon and/or a visual emergency beacon, such as a strobe, in addition to or in place of a radio beacon. In one embodiment, the beacon is not activated unless the mobile telephone is unable to complete the call to the emergency number. In another embodiment, the beacon is activated without receiving any remote authorization from, for example, a 9-1-1 call center.
