ANORDNUNG ZUR VERBESSERUNG DER SPRACHQUALITÄT FÜR VOICE-OVER-IP-(VOIP)-ANRUFE

摘要

The present invention relates to an arrangement for improving the speech quality, especially for VoIP (Voice over IP) calls, which arrangement comprises a Transceiver and Rate Adapter Unit (TRAU) in which an encoded speech signal from a Mobile Station (MS) is transcoded, and for the purpose of reducing the necessary encoding/decoding for thereby avoiding detorioration of speech quality, and also for the purpose of avoiding reduction in bandwidth, it is according to the present invention suggested that said arrangement comprises means for either putting the TRAU in a transparent mode or letting the TRAU be bypassed altogether.
