| 摘 要： | 在GSM无线网络中，对无线质量的评估是通过RXQUAL来实现的。但是无线网络的语音是经过话音编码及信道编码两个过程的，RXQUAL只能反映出网络在空中接口上的传输质量，并不能反映终端用户对无线网络语音保真度的最终感受。为此爱立信提出了一个能够表达终端用户对无线网络质量直接感受的指标—SQI。

| Abstract: | In the GSM wireless network, the assessment of wireless quality is achieved by RXQUAL. But the voice of wireless network comes through two processes which is voice coding and channel coding. RXQUAL can only reflect the network＇s transmission quality of the Um interface. And it does not reflect the final experience to wireless network voice fidelity coming from the end-user. For this reason, Ericsson proposed to express an end-user experience for wireless network quality indicators-SQI. |
