ABSTRACT:
A method to detect a presence of a hangover period in a speech decoder in a communication system that utilizes discontinuous transmission between a transmitter and a receiver. The discontinuous transmission is defined by temporally sequential frame periods of which some periods will contain a transmitted frame and some periods will contain no transmission. The discontinuous transmission is constituted by information transmission periods of at least one frame that contain information given by a user to the transmitter, and silence periods having a length of at least one frame period and containing other information than that given by the user. An irregularly occurring period (T) of at least one frame exists between an information transmission period and the following silence period, the irregularly occurring period forming a hangover period for determining the information relating to the silence period. In the receiver the number of frame periods is counted until a certain moment; the beginning of the silence period is detected; and, based on said counted number of frame periods and the beginning of the silence period, a determination is made whether or not there is a hangover period (T) between the information transmission period and the silence period.
