Abstract
The invention is, in one embodiment, a method of reporting the location of a mobile phone by locating a Global Positioning System (GPS) receiver in a mobile communications network. The method first determines the location of the GPS receiver, processes data identifying the location, then synthesizes the location information into a Tele-type (TTY/TDD) compatible format and transmits the location. A TTY/TDD device at a receiving station will process the location data to identify the location of the mobile phone. In one aspect, the method is implemented through modular programming. The invention is also a mobile phone capable of transmitting location information gathered by a Global Positioning System (GPS) receiver to a Public Safety Answering Point (PSAP). The mobile phone houses a transceiver, a GPS receiver, and a Tele-type (TTY/TDD) synthesizer in communication with the GPS receiver and the transceiver.
