Abstract: A method for communicating half-rate encoded voice frames. The method includes receiving, by a digital signal processor, a half-rate encoded voice frame. The method further includes determining, by the digital signal processor, a network access code. The method further includes encoding, by the digital signal processor, a network identifier based on the network access code. The method further includes scrambling, by the digital signal processor, the network identifier to generate a scrambled network identifier. The method further includes generating, by the digital signal processor, an erasure pattern. The method further includes generating, by the digital signal processor, a half-rate embedded voice code word based on the erasure pattern and the half-rate encoded voice frame. The method further includes generating, by the digital signal processor, a half-rate embedded logical data unit based on the half-rate embedded voice code word and the scrambled network identifier.

Abstract: A method, system and device enable transferring an audio signal between devices of a single user. The method includes pairing, over a master-less communication link, a narrowband communication device operating in a narrowband communication system and a broadband communication device operating in a broadband communication system. A call is then established between the narrowband communication device and the narrowband communication system or between the broadband communication device and the broadband communication system. Next, an audio quality parameter is determined at least one of the narrowband communication device and the broadband communication device. An audio signal of the call is then transmitted, over the master-less communication link and in response to the audio quality parameter, from one to the other of the broadband communication device and the narrowband communication device.
