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.

Claims

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 transmitting the acoustic signals representing geographic position to said microphone, whereby the position of said locator module is transmitted over a voice channel by said wireless transmitter.

2. The system of claim 1, wherein said acoustic coupling unit includes an acoustic projector and means for affixing said projector adjacent said microphone.

3. The system of claim 2, wherein said acoustic coupling unit overlies said microphone.

4. The system of claim 3, wherein said acoustic coupling unit permits sounds generated from other than said projector to reach said microphone.

5. The system of claim 1, wherein said locator includes a cradle into which said wireless transmitter is adapted to fit, said cradle positioning said acoustic coupling unit adjacent said microphone when said transmitter is in said cradle.

6. The system of claim 1, wherein said locator module includes a geoposition determining element.

7. The system of claim 4, wherein said geoposition determining unit includes a GPS receiver.

8. The system of claim 6, wherein said locator module includes a speech synthesizer coupled to said geoposition determining unit for generating a verbal rendition of the position determined thereby.

9. The system of claim 6, wherein said locator module includes a DTMF encoder coupled to said geoposition determining unit for generating an audible tone rendition of the position determined thereby.

10. The system of claim 1, wherein said locator module generates acoustic signals coupled to said acoustic coupler unit carrying information other than position information.

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;

converting the determined location to a acoustic signal; and

,

coupling the acoustic signal to the microphone via an acoustic coupler, whereby the transmitter can be adapted to provide position reporting without any change thereto.

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.
