Method and apparatus for automatic volume control
First Claim
1. An apparatus for automatically controlling a volume level of an audio signal transmitted to or received by a mobile station within a telecommunications network for one or more subscribers, the apparatus comprising:
- a noise measuring device for measuring a noise external to communication with the mobile station;
a volume controller communicably coupled to the noise measuring device for adjusting the gain of the audio signal transmitted to or received by the mobile station based on a volume control data corresponding to the subscriber and the noise, and for updating the volume control data corresponding to the subscriber and the noise whenever the subscriber manually adjusts a volume level of the audio signal; and
a memory module communicably coupled to the volume controller for storing the volume control data.

Abstract
An apparatus (100) is disclosed for automatically controlling the volume level of an audio signal transmitted to or received by a mobile station and/or terminal within a telecommunications network, the apparatus including a noise measuring device (102), a volume controller (104) communicably coupled to the noise measuring device, and a memory module (108) communicably coupled to the noise measuring device. In a wireless telecommunications network, the memory module may comprise a subscriber identity module (SIM) and contain preferred volume levels for given levels of noise for that particular subscriber. A method is also disclosed for automatically controlling the volume level of an audio signal transmitted to or received by a phone terminal and/or mobile station within a telecommunications network, comprising the steps of obtaining measurements of a background noise signal, obtaining a preferred volume level corresponding to the measurement of a background noise signal, and automatically adjusting the volume level of the audio signal to the preferred volume level.

7. An apparatus for automatically controlling a volume level of an audio signal transmitted to or received by a mobile station within a wireless telecommunications network for one or more subscribers, the apparatus comprising:
-
a noise measuring device for measuring a noise external to communication with the mobile station;
a volume controller communicably coupled to the noise measuring device for adjusting the gain of the audio signal transmitted to or received by the mobile station based on an input from a subscriber identity module, and for updating the volume control data corresponding to the subscriber and the measurement of the noise whenever the subscriber manually adjusts a volume level of the audio signal; and
the subscriber identity module communicably coupled to the noise measuring device for identifying the subscriber and in communication with the volume controller for providing the input to the volume controller, wherein the input is based on the volume control data corresponding to the subscriber and the measurement of the noise. - View Dependent Claims (8, 9, 10)

16. A method of automatically controlling the volume level of an audio signal transmitted to or received by a mobile station within a telecommunications network for one or more subscribers, comprising the steps of:
-
receiving a first audio signal wherein the first audio signal comprises speech;
receiving a second audio signal wherein the second audio signal comprises background noise;
obtaining a preferred volume level corresponding to the subscriber and the level of the second audio signal;
obtaining a third audio signal by filtering the first audio signal;
automatically adjusting the volume level of the third audio signal to the preferred volume level; and
updating the preferred volume level corresponding to the subscriber and the level of the second audio signal whenever the subscriber manually adjusts the volume level of the third audio signal. - View Dependent Claims (17, 18, 19)
