Abstract

A system and method for routing audio for a vehicle mounted communication system includes activating (210) a (Push-To-Talk) PTT button associated with a handheld or rear microphone and determining (220) whether a short range wireless device is operationally coupled with the vehicle mounted communication device. In accordance with an embodiment, first audio signals received (260) from a microphone of the short range wireless device are transmitted to a remote party (265) when the short range wireless device is operationally coupled to the vehicle mounted communication device. Second audio signals received (270) from a remote party are routed (275) to a speaker of the short range wireless device, when the short range wireless device is operationally coupled with the vehicle mounted communication device and the PTT button is activated.

Claims

1. A vehicle mounted communication system comprising:

a mobile radio comprising;

a radio processor;

a transceiver operatively coupled to the radio processor;

a short range communication module operatively coupled to the transceiver;

a microphone coupled to the mobile radio, wherein the microphone comprises a (Push-To-Talk) PTT button;

the microphone operates in one of an on-hook mode of operation and an off-hook mode of operation; and

a short range wireless headset operatively coupled to the short range communication module, the short range wireless headset having audio selectively routed thereto in response to the operating mode of the microphone being on-hook.

2. The vehicle mounted communication system of claim 1 further comprising:

an indicator for indicating a status of a connection between the short range communication module and the short range wireless headset.

3. The vehicle mounted communication system of claim 1, wherein the radio processor receives the audio from the microphone in response to activation of the PTT button, while the short range wireless headset is operatively coupled to the short range communication module and the microphone is operating in the off-hook mode.

4. The vehicle mounted communication system of claim 3, further comprising:

a front speaker, comprised in the vehicle mounted communication system, transmitting received audio signals, when the microphone is operating in the off-hook mode.

5. The vehicle mounted communication system of claim 3 further comprising:

a public address switch for activating a Public Address mode, wherein on activation of the Public Address switch the audio, from the microphone, is routed to an auxiliary speaker associated with the mobile radio.

6. The vehicle mounted communication system of claim 1, wherein the radio processor routes received audio signals to a speaker, comprised in the short range wireless headset, when the microphone is operating in the on-hook mode.

7. The vehicle mounted communication system of claim 1, wherein the short range wireless headset is a Bluetooth headset.

8. The vehicle mounted communication system of claim 1 further comprising:

a public address switch for activating a Public Address mode, wherein on activation of the Public Address switch the audio, from the short range wireless headset, is routed to an auxiliary speaker associated with the mobile radio.

9. A method of routing audio for a vehicle mounted communication system, the method comprising:

activating a (Push-To-Talk) PTT button associated with a handheld microphone;

determining whether a short range wireless device is operationally coupled with a wireless communication module, comprised in the vehicle mounted communication device;

determining whether the handheld microphone is operating in an on-hook or an off-mode; and

receiving first audio signals from a microphone, comprised in a short range wireless device, when the short range wireless device is operationally coupled with the wireless communication module and the handheld microphone is operating in the on hook mode.

10. The method of claim 9, further comprising:

receiving the first audio signals from the handheld microphone, when the short range wireless device is operationally coupled with the wireless communication module and the handheld microphone is operating in the off-hook mode.

11. The method of claim 10 further comprising:

routing the first audio signals, from the handheld microphone, to an auxiliary speaker associated with the vehicle mounted communication device on activation of a public address switch.

12. The method of claim 9, further comprising:

indicating a status of a connection between the short range wireless device and the wireless communication module.

13. The method of claim 9, further comprising:

routing second audio signals to a speaker, comprised in the short range wireless device, when the handheld microphone is operating in the on-hook mode.

14. The method of claim 9 further comprising:

routing the first audio signals, from the microphone, to an auxiliary speaker associated with the vehicle mounted communication system on activation of a public address switch.

15. A vehicle mounted communication system comprising:

a rear microphone;

a rear (Push-To-Talk) PTT button associated with the rear microphone; and

a processor coupled to the rear PTT button, the processor for;

instructing a transceiver, comprised in the vehicle mounted communication system, for receiving first audio signals from a microphone, comprised in a short range wireless device, on press of the rear PTT, while the short range wireless device is operationally coupled to the vehicle mounted communication system.

16. The vehicle mounted communication system of claim 15 further comprising:

an indicator for indicating a status of a connection between the vehicle mounted communication system and the short range wireless device.

17. The vehicle mounted communication system of claim 15, wherein the processor routes received audio signals to a speaker, comprised in the short range wireless device.

18. The vehicle mounted communication system of claim 17, wherein the received audio signals are received from a remote party.

19. The vehicle mounted communication system of claim 17, wherein the short ranged wireless device is a Bluetooth headset.

20. The vehicle mounted communication system of claim 17 further comprising:

a public address switch for activating a PA mode, wherein on activation of the Public Address switch the first audio signals, from the microphone, is routed to an auxiliary speaker associated with the vehicle mounted communication system.

21. A method of routing audio for a vehicle mounted communication system, the method comprising:

activating a rear (Push-To-Talk) PTT button associated with a rear microphone;

determining whether a short range wireless device is operationally coupled with a wireless communication module, comprised in the vehicle mounted communication system; and

receiving first audio signals from a microphone comprised, in the short range wireless device, when the short range wireless device is operationally coupled with the vehicle mounted communication device.

22. The method of claim 21, further comprising:

routing second audio signals to a speaker, comprised in the short range wireless device.

23. The method of claim 21, further comprising:

indicating a status of a connection between the short range wireless device and the wireless communication module.

24. The method of claim 21 further comprising:

routing the first audio signals, from the microphone, to an auxiliary speaker associated with the vehicle mounted communication device on activation of a public address switch.

25. The method of claim 21 further comprising:

routing the first audio signals, from the rear microphone, to an auxiliary speaker associated with the vehicle mounted communication system on activation of a public address switch, when the short range wireless device is not coupled with the wireless communication module.
