Abstract:
1. A method of managing a communication path in a communication network, the method comprising: estimating a total voice quality metric for a communication path in the communication network, wherein estimating the total voice quality metric comprises subtracting voice signal impairments from a voice signal quality score, wherein the voice signal impairments comprises impairments associated with one or more radio frequency (RF) links in the communication network and impairments associated with one or more vocoders in the communication network, wherein impairments associated with one or more vocoders comprise a baseline vocoder quality for each of the one or more vocoders in the system, a vocoder quality degradation due to bit error or packet loss for each of the one or more vocoders, and a vocoder delay for each of the one or more vocoders and at least one of: selecting a communication path based on the total voice quality metric estimation.
