摘要： After a call is established between two stations using a codec that has been negotiated during call setup, in-band signaling may be used between the two stations to change the codec that is to be used. The in-band signals are indicative that the station that is transmitting the in-band signals can operate with a second codec and are used to probe whether the receiving station can also operate with that second codec. If the receiving station detects and reacts to the in-band signals, then both stations change to communicate with the second codec. The second codec has compatible packet sizes of the deployed (originally negotiated) codec without any need of infrastructure upgrade and/or quality compromise to legacy phone users (i.e., stations that cannot operate with the second codec).

摘要： A communication system for use in a wireless network includes: an audio module configured to provide packets indicative of audio for a part of a communication between the communication system and another communication system, the communication spanning packet times, the packets including at least critical packets indicative of critical audio; and a transceiver coupled to the audio module and configured to cause: the critical packets to be conveyed for transmission; and first non-critical packets, indicative of non-critical audio, to be conveyed for transmission such that (1) the first non-critical packets represent less than all of a time between transmission of critical packets and (2) no more than a threshold number of packet times will pass without one of the critical packets or one of the first non-critical packets being conveyed by the transceiver for transmission.
