Burst packet loss and enhanced packet loss-based quality model for mobile voice-over Internet protocol applications

Voice over Internet protocol (VoIP) quality monitoring platforms need to be as simple as possible, especially at low capacity end-points, such as smart phones. The existing simple packet loss-based quality model, with only the input metric of the packet loss parameter, needs to be enhanced to increase the accuracy of quality prediction while ensuring that implementation is simple. Several burstiness parameters for describing burst loss characteristics in VoIP packet streams has been presented. The authors investigate how closely each one is correlated to perceptual quality. Then, from the correlation results, two dominant parameters are chosen that will be used as additional input metrics to increase the accuracy of quality prediction. A packet loss-based and enhanced quality prediction model is also proposed for VoIP services over the Internet. This can replace the speech quality estimation model in ITU G.1070, which aims to implement VoIP quality monitoring platforms at low capacity end-points. Thus, mobile end-points, such as smart phones, can embed the proposed quality prediction model to measure VoIP quality on a real-time basis.
