摘要
提供高清语音及更短接续时延是VoLTE业务的主要优势,同时也面临着端到端业务实现流程复杂,涉及环节较多的问题。从用户使用感知的角度,提出基于端到端的VoLTE通话质量优化方法,从VoLTE网络架构入手探讨影响VoLTE语音质量的关键因素,并对端到端不同环节遇到的问题逐一进行阐述分析并给出切实有效的优化解决方案。
Providing high definition voice and shorter time delay is the main advantage of VoLTE services.Because of the high frequency band of TD-LTE system,there must be some weak coverage.From the perspective of the user's perception,this paper discusses how to improve the quality of VoLTE calls in weak coverage scenarios,and puts forward the optimization solutions for the wide area scene and the urban area.
