The invention relates to a method of processing a speech frame in a radio system, a radio system, a mobile station in a radio system, and a network of a radio system. In the method (502) a speech frame having propagated over a radio path is channel-decoded. If (506, 522) on the basis of the channel-decoding the speech frame is free of defects, (508) it is inferred from the value of at least one speech parameter in the channel-decoded speech frame whether the speech frame contains speech that is decodable by means of a speech decoder; and (510, 526) if, according to the inference, the speech frame does contain speech that is decodable by means of a speech decoder, (512) the speech frame is decoded by means of a speech decoder; and (510, 524) if, according to the inference, the speech frame does not contain speech that would be decodable by means of the speech decoder, (514) the speech frame is not decoded. <IMAGE> |
