Abstract:
1. A mobile station comprising: transmission means and reception means for receiving and transmitting signals via a radio path; a user interface with a microphone for receiving sound signals; control means for utilizing discontinuous transmission, whereby the control means comprises signal processing means for processing the sound signals received through the microphone by utilizing filter parameters or a threshold value, which indicate how speech and background noise received via the microphone should be discriminated, and which are stored in the mobile station, in order to detect speech from the sound signals received through the microphone; detection means for detecting a predetermined control signal received by the reception means via the radio path; and regulation means, responsive to the detection means, for changing said filter parameters or said threshold value which indicate how speech and background noise received via the microphone should be discriminated and which are utilized in speech detection, in such a manner that the signal processing means interprets the sound signals received through the user microphone as background noise more seldom or more often.
