Abstract

A method for muting a Bluetooth device is described. The method includes receiving, by a Bluetooth controller of the Bluetooth device, a mute remote microphone message from a peer Bluetooth device. The method also includes disabling audio transmission functionality of the Bluetooth device. The Bluetooth device may also receive a disable remote mute message from the peer Bluetooth device and enable the audio transmission functionality of the Bluetooth device.

Claims

1. A method for muting a Bluetooth device, comprising:

receiving, by a Bluetooth controller, a mute remote microphone message from a peer Bluetooth device; and

disabling audio transmission functionality of the Bluetooth device in response to receiving the mute remote microphone message, wherein disabling audio transmission functionality of the Bluetooth device comprises disabling microphone path codec processing of the Bluetooth device and disabling audio-related wireless transmissions from the Bluetooth device to the peer Bluetooth device.

2. The method of claim 1, wherein the Bluetooth device is a headset, headphones or automobile hands-free audio system.

3. The method of claim 1, further comprising:

receiving a disable remote mute message from the peer Bluetooth device; and

enabling the audio transmission functionality of the Bluetooth device.

4. The method of claim 1, further comprising:

generating, at the Bluetooth controller, a mute local microphone message in response to receiving the mute remote microphone message; and

sending the mute local microphone message from the Bluetooth controller to a host of the Bluetooth device, wherein the host disables the audio transmission functionality in response to the mute local microphone message.

5. The method of claim 1, wherein the mute remote microphone message is communicated from the peer Bluetooth device to the Bluetooth device via one of a link layer control procedure, link manager protocol or Qualcomm link layer (QLL) procedure.

7. The method of claim 1, wherein disabling audio transmission functionality of the Bluetooth device comprises disabling voice activity detection.

9. The method of claim 1, wherein the Bluetooth device receives the mute remote microphone message from the peer Bluetooth device when mute is enabled at a user interface of the peer Bluetooth device.

10. A Bluetooth device, comprising:

a processor;

a memory in communication with the processor; and

instructions stored in the memory, the instructions executable by the processor to;

receive, by a Bluetooth controller, a mute remote microphone message from a peer Bluetooth device; and

disable audio transmission functionality of the Bluetooth device in response to receiving the mute remote microphone message, wherein the instructions executable to disable audio transmission functionality of the Bluetooth device comprise instructions executable to disable microphone path codec processing of the Bluetooth device and disable audio-related wireless transmissions from the Bluetooth device to the peer Bluetooth device.

11. The Bluetooth device of claim 10, wherein the Bluetooth device is a headset, headphones or automobile hands-free audio system.

12. The Bluetooth device of claim 10, further comprising instructions executable to:

receive a disable remote mute message from the peer Bluetooth device; and

enable the audio transmission functionality of the Bluetooth device.

13. The Bluetooth device of claim 10, further comprising instructions executable to:

generate, at the Bluetooth controller, a mute local microphone message in response to receiving the mute remote microphone message; and

send the mute local microphone message from the Bluetooth controller to a host of the Bluetooth device, wherein the host disables the audio transmission functionality in response to the mute local microphone message.

15. The Bluetooth device of claim 10, wherein the mute remote microphone message is communicated from the peer Bluetooth device to the Bluetooth device via one of a link layer control procedure, link manager protocol or Qualcomm link layer (QLL) procedure.

16. The Bluetooth device of claim 10, wherein the instructions executable to disable audio transmission functionality of the Bluetooth device comprise instructions executable to disable voice activity detection.

18. The Bluetooth device of claim 10, wherein the Bluetooth device receives the mute remote microphone message from the peer Bluetooth device when mute is enabled at a user interface of the peer Bluetooth device.

14. (canceled)

17. (canceled)

19. A method for muting a remote Bluetooth device by a peer Bluetooth device, comprising:

detecting that mute is enabled at the peer Bluetooth device;

generating a mute remote microphone message to disable audio transmission functionality of the remote Bluetooth device; and

sending, by a Bluetooth controller of the peer Bluetooth device, the mute remote microphone message to the remote Bluetooth device, wherein the remote Bluetooth device disables microphone path codec processing and disables audio-related wireless transmissions to the peer Bluetooth device upon receiving the mute remote microphone message.

20. The method of claim 19, wherein the remote Bluetooth device is a headset, headphones or automobile hands-free audio system.

21. The method of claim 19, further comprising:

detecting that mute is disabled at a user interface of the peer Bluetooth device;

generating a disable remote mute message; and

sending, by the Bluetooth controller of the peer Bluetooth device, the disable remote mute message to the remote Bluetooth device.

22. The method of claim 19, wherein the mute remote microphone message is communicated from the peer Bluetooth device to the remote Bluetooth device via one of a link layer control procedure, link manager protocol or Qualcomm link layer (QLL) procedure.

24. The method of claim 19, wherein the remote Bluetooth device disables voice activity detection upon receiving the mute remote microphone message.

23. (canceled)

25. (canceled)

26. A peer Bluetooth device, comprising:

a processor;

a memory in communication with the processor; and

instructions stored in the memory, the instructions executable by the processor to;

detect that mute is enabled at the peer Bluetooth device;

generate a mute remote microphone message to disable audio transmission functionality of a remote Bluetooth device; and

send, by a Bluetooth controller of the peer Bluetooth device, the mute remote microphone message to the remote Bluetooth device, wherein the remote Bluetooth device disables microphone path codec processing and disables audio-related wireless transmissions to the peer Bluetooth device upon receiving the mute remote microphone message.

27. The peer Bluetooth device of claim 26, further comprising instructions executable to:

detect that mute is disabled at a user interface of the peer Bluetooth device;

generate a disable remote mute message to enable audio transmission functionality of the remote Bluetooth device; and

send, by the Bluetooth controller of the peer Bluetooth device, the disable remote mute message to the remote Bluetooth device.

29. The peer Bluetooth device of claim 26, wherein the remote Bluetooth device disables voice activity detection upon receiving the mute remote microphone message.
