System for location reporting
First Claim
1. A system for reporting location of a wireless caller, comprising:
- a wireless transmitter having a microphone for generating acoustic signals to be wirelessly transmitted over a voice channel to a receiver where the acoustic signals are made available as an output thereof;
a locator module for generating acoustic signals representing the geographic position of said module; and
, an acoustic coupling unit coupled to said module and positioned adjacent said microphone for automatically coupling the acoustic signals representing geographic position to said microphone without human intervention, whereby the position of said locator module is transmitted over a voice channel by said wireless transmitter.

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.

11. A method of adapting a transmitter having a microphone and capable of transmitting information on a voice channel to transmit the position of the transmitter without modification thereof, comprising the steps of:
-
determining the location of the transmitter with a geoposition determining unit so as to produce a signal representing determined location, converting the determined location to a synthetic acoustic signal without human intervention and, coupling the acoustic signal to the microphone via an acoustic coupling device, whereby the transmitter can be adapted to provide position reporting without any change thereto and without human intervention.

12. A method of adapting a transmitter having a case and a microphone and capable of transmitting information on a voice channel to transmit the position of the transmitter without modification thereof, comprising the steps of:
-
determining the location of the transmitter using a geoposition determining unit which provides a determined location signal as an output;
converting the determined location signal to an acoustic signal without human intervention; and
,coupling the acoustic signal with an acoustic coupling device to the microphone of the transmitter from a position outside the case of the transmitter, whereby the transmitter can be adapted to provide position reporting without any change thereto from a position outside the case of the transmitter. - View Dependent Claims (13, 14)
