“Transcoder Bypass In Mobile Handset For Voip Call With Bluetooth Headsets”
Abstract: The application relates to VoIP calls between terminals comprising Bluetooth chipsets. Bluetooth headsets employ audio codes covering the audio spectrum up to 20 kHz whereas speech codecs for VoIP only cover up to 7 kHz. The transcoding between audio and speech codes has several disadvantages such as lower voice quality and excessive latency due to the two coding processes. These disadvantages are overcome in that transcoding is bypassed. At the beginning of a VoIP call, the specific audio codec information associated with the Bluetooth headset is included in a network signaling message and communicated to the network and the remote terminal. If both parties support the audio codec, the audio signal encoded by the Bluetooth headset is communicated directly to the remote terminal without any transcoding by the terminal, thereby bypassing de- and encoding within the terminal.
