First Claim
Patent Images
1. A method in a mobile communications handset device, comprising:
- performing an ambient noise suppression process upon an uplink signal that contains speech of a near-end user of the device, wherein the uplink signal is transmitted to a far-end user during a call and the ambient noise suppression process is to reduce an amount of background or ambient sound that is also in the uplink signal;
detecting that the near-end user has moved the device from an at-the-ear position to an away-from-the-ear position during the call; and
in response to said detection, disabling the ambient noise suppression process.

Abstract
A method in a communications device includes the following operations. During a call, a process automatically detects that the device has moved from an at-the-ear position to an away-from-the-ear position. Based on the detection, a noise suppressor that operates upon an uplink signal for the call is signaled to change its noise suppression performance. Other embodiments are also described and claimed.

6. A mobile communications handset device comprising:
-
a radio; an uplink audio signal processor to deliver an uplink audio signal to the radio, the uplink processor having an ambient noise suppressor; a downlink audio signal processor to receive a downlink audio signal from the radio; and decision logic to automatically detect that a user has moved the device from an at-the-ear position to an away-from-the-ear position, and in response disable the ambient noise suppressor. - View Dependent Claims (7, 8, 9)
