IDENTIFYING AND TRANSITIONING TO AN IMPROVED VOIP SESSION

摘要

Qualities of each of first and second sessions for voice over internet protocol communication between endpoints are assessed and compared, and the endpoints signaled to select the session having the higher assessed quality as a current or primary session for further data packet communication between the endpoints, and to remove the lower quality session from use as a session for the further data packet communication between the endpoints, or to use the lower quality session as a secondary session for data communication between the endpoints. More particularly, the assessed qualities of each of the current and second sessions meet a basic requirement defined to provide voice over internet protocol data packet communication between the endpoints.

1. A computer-implemented method for establishing and selecting session connections in response to voice over internet protocol quality determinations, comprising executing on a processing unit the steps of:
comparing a latency of audio data packets transiting between a pair of endpoints in a network over a first session that is established for voice over internet protocol communication between the endpoints, to a latency of audio data packets transiting between the pair of endpoints in the network over a second session that is established for voice over internet protocol communication between the endpoints; signaling the endpoints to select one of the first and second sessions that has a lower value of the compared determined latencies by a difference ranging from 375 milliseconds to 425 milliseconds as a primary session for communicating between the endpoints at least one of audio packet data, video packet data, original packet data and resource reservation protocol packet data; and signaling the endpoints to select another of the first and second sessions that is not selected as the primary session as a secondary session for communicating between the endpoints at least one of non-audio packet data, non-video packet data, packet data that is redundant to the original packet data communicated on the primary session, non-resource reservation protocol packet data, and non-priority packet data; and wherein the latencies of the voice over internet protocol communication audio data packets transiting between the endpoints over the first and second sessions each meet a basic requirement defined to provide good voice over internet protocol data packet communication between the endpoints.
