This article mainly introduces the influence of packet loss on the speech perception in VoLTE networks

and analyzes the reasons of the high packet loss rate of VoLTE. In this paper

the author introduces the methods from three aspects（capacity

coverage and interference） to reduce the packet loss rate

and finally achieved good results

greatly reduces the packet loss rate of VoLTE network

improves customer perception. It can be a very useful reference for the telecommunication operators and LTE network optimization engineers.
