Abstract

A user'"'"'s wireless communication device communicates cellular signals with a remote party over a wireless communications network and short-range wireless signals with a headset worn by the user. Upon receiving an incoming call, a controller in the user'"'"'s device determines whether a microphone integrated with the user'"'"'s device, or a microphone integrated with the headset, is closest to the user'"'"'s mouth. Based on that determination, the controller routes the incoming audio signals to whichever speaker is associated with the microphone that is closest to the user'"'"'s mouth.

Claims

1. A wireless communication device configured to communicate short-range wireless signals with a corresponding headset, the wireless communication device comprising:

a microphone;

a speaker;

a short-range transceiver configured to communicate with the headset; and

a controller configured to;

measure an audio reception quality for the microphone at the wireless communication device;

measure an audio reception quality for a microphone at the headset; and

route audio signals associated with the incoming call to the speaker at the wireless communication device, or to a speaker at the headset, based on the measured audio reception qualities.

2. The wireless communication device of claim 1 wherein the controller is further configured to:

determine which of the microphones is positioned closest to the user'"'"'s mouth based on the measured audio reception qualities; and

route the audio signals associated with the incoming call to the speaker associated with the microphone that is closest to the user'"'"'s mouth.

3. The wireless communication device of claim 2 wherein the controller is configured to route the audio signals associated with the incoming call to the speaker at the wireless communication device if the controller determines that the microphone at the wireless communication device is closer to the user'"'"'s mouth than the microphone at the headset.

4. The wireless communication device of claim 2 wherein the controller is configured to route the audio signals associated with the incoming call to the speaker at the headset if the controller determines that the microphone at the headset is closer to the user'"'"'s mouth than the microphone at the wireless communication device.

5. The wireless communication device of claim 2 wherein the controller is configured to route the audio signals associated with the incoming call to a default speaker if the controller is unable to determine which of the microphones is closest to the user'"'"'s mouth.

6. The wireless communication device of claim 5 wherein the default speaker comprises the speaker at the wireless communication device.

7. The wireless communication device of claim 5 wherein the default speaker comprises the speaker at the corresponding headset.

8. The wireless communication device of claim 1 wherein the controller is further configured to enable both of the microphones responsive to receiving user input to accept incoming call.

9. The wireless communication device of claim 8 wherein the controller is further configured to:

poll both of the microphones to detect audible sound; and

individually measure the audio reception qualities at both of the microphones based on the audible sound detected at both microphones.

10. A method of routing audio signals associated with an incoming call received at a wireless communication device configured to communicate with a corresponding headset, the method comprising:

measuring an audio reception quality for a microphone at the wireless communication device;

measuring an audio reception quality for a microphone at the corresponding headset; and

routing audio signals associated with an incoming call to a speaker at the wireless communication device, or to a speaker at the headset, based on the measured audio reception qualities.

11. The method of claim 10 further comprising:

determining which of the microphones is positioned closest to a user'"'"'s mouth based on the measured audio reception qualities; and

routing the audio signals associated with the incoming call to the speaker associated with the microphone that is closest to the user'"'"'s mouth.

12. The method of claim 11 further comprising routing the audio signals associated with the incoming call to the speaker at the wireless communication device if the microphone at the wireless communication device is closer to the user'"'"'s mouth than the microphone at the headset.

13. The method of claim 11 further comprising routing the audio signals associated with the incoming call to the speaker at the headset if the microphone at the headset is closer to the user'"'"'s mouth than the microphone at the wireless communication device.

14. The method of claim 11 further comprising routing the audio signals associated with the incoming call to a default speaker if the wireless communication device is unable to determine which of the microphones is closest to the user'"'"'s mouth.

15. The method of claim 14 wherein the default speaker comprises the speaker at the wireless communication device.

16. The method of claim 14 wherein the default speaker comprises the speaker at the corresponding headset.

17. The method of claim 10 further comprising enabling both of the microphones to detect audible sound responsive to receiving user input to accept incoming call.

18. The method of claim 17 further comprising:

polling both of the microphones to detect audible sound; and

individually measuring the audio reception qualities at both of the microphones based on the audible sound detected at both microphones.
