摘　　要：VoLTE业务是基于IMS网络的LTE语音解决方案。其是架构在LTE网络上、全IP条件下、基于IMS Server的端到端语音方案。而丢包率是影响业务感知的关键因素。本文主要分析了QCI1上行NI频选功能、TTI bundling、QCI1预调度、PDCCH自适应、CMR功能等新技术,以改善丢包率。VoLTE Service is based on Ims Network Lte Voice Solution.It is an end-to-end voice scheme based on IMS Server over LTE network and all IP.This paper mainly analyzed the new technologies of qci1 uplink Ni frequen cy selection function,TTI Bundling,QCI1 pre scheduling,PDCCH adaptive,CMR function and so on,in order to im prove the packet loss rate.
