| 摘 要： | 针对目前IP电话语音质量难以准确评价及测量的情况,研究了一种基于E-Model的VoIP(voice over internet protocol)语音质量的测量模型。该模型考虑了IP网络中大多数的网络损伤因素,并能容易地计算出不同丢包率、不同的延迟和抖动所对应的MOS(mean opinion score)值。测试出IP电话在网络中质量变化情况,有利于IP网络中资源的调整和VoIP质量的提高。

| Abstract: | To evaluate and measure the speech quality of VoIP(voice over internet protocol) accurately,this paper mainly researched the measurement method of the speech quality of VoIP based on E-Model.The model considered most of the impairment factor of the network in the IP network,and could easily calculate MOS(mean opinion score) values for the different packet loss rate,different delay and jitter.It tested out changes of quality of the IP phones in the network,which was conducive to adjust the resources in the I... |
