随着网络技术不断发展,基于IP的语音如雨后春笋般层出不穷,但得到运营商广泛认可且效果较好的当属VOLTE。相较其它IP语音,VOLTE可为用户提供电信级的可靠服务,相对传统语音,用户可获得更好的语音质量、更短的接续时延,未来注定成为众多用户的必然选择。但目前VOLTE技术处于商用初期,虽总体感知良好,但概率性、偶发性单通、吞字问题成为影响客户感知的焦点,必须进行优化。本文对影响VOLTE语音质量的因素和优化方法进行了分析研究。
As network technology continues to evolve, voice over IP is mushroomed, but it is VOLTE, which is widely accepted by operators and works well. Compared with other IP voices, VOLTE can provide users with carrier-class and reliable services. Compared with traditional voice, users can obtain better voice quality and shorter connection delay, and the future is destined to become the inevitable choice of many users. However, at present, VOLTE technology is in the early stage of business. Although the overall perception is good, probabilistic and sporadic one-way and swallow-word problems have become the focus of customer perception and must be optimized. This article analyzes the factors that affect VOLTE voice quality and the optimization methods.
