Abstract
An audio coupling is provided between a location reporting unit and the microphone of a wireless phone in which location information is provided either by synthesized voice and/or DTMF tones through the audio coupling to the microphone such that the location of the wireless phone can be broadcast on the normal voice channel to a dispatch operation such as a Public Safety Answering Point or to a location-based service provider. The subject interface makes possible the adaptation of any wireless phone to provide location-based information without change to the wireless phone and without any additional infrastructure for the wireless network. The utilization of synthesized speech and/or DTMF tones over the voice channel provides a universality for the system, which can be utilized anywhere where there is both wireless and GPS satellite coverage.
