基于路损差的VoLTE感知问题分析方法与应用

Research and application of uplink limitation of VoLTE services based on path loss difference

VoLTE部署以来,由于上行链路受限,严重影响了VoLTE业务质量和用户感知.同时对上行受限问题缺乏统计性量化分析手段,使得上行受限问题的发现和解决较为困难,VoLTE业务提升工作急需有效的解决手段.通过研究上行受限问题的统计性量化分析方法,发现了路损差值、PHR两项性能指标能够准确表征上行受限程度.基于这两项性能指标,实现了对VoLTE业务上行受限问题的评估及上行受限区域的精准识别,对VoLTE业务的质量提升起到了积极的促进作用.

Since the deployment of voLTE,the uplink quality is limited,which seriously affects the service quality and user perception of voU’E.At the same time.due to the lack of statistical quantitative analysis methods for the uplink limited problem.it iS difficult to find and solve the uplink limited problem.VbLTE’S business improvement work urgently needs an effective solution.Through the research on the statistical quantitative analysis method of the uplink limited problem,this paper finds the path loss difference,and the two performance indexes of PHR can accurately represent the degree of uplink limited.Based on these two performance indexes.the evaluation of the VroLTE service uplink limitation problem and the accurate recognition of uplink limited areas iS realized.it has a positive effect on the quality improvement ofVoLTE’S business.
