摘要

承载于 LTE 的语音业务（VoLTE）无线频谱利用效率优于传统 CS 语音，高清语音和视频编解码的引入显著提高了通信质量，VoLTE 呼叫接续时长较传统CS 语音大幅缩短。主要针对 VoLTE 的接续时延，提出基于信令消息的 VoLTE 接续时延优化，依据 VoLTE 终端在接续过程中不同阶段的网元间交互的信令消息，从寻呼、域选、资源预留3个阶段分别对影响 VoLTE 接续时延的因素进行针对性分析，并给出相应的解决方案。

Abstract

VoLTE wireless spectrum utilization efficiency is better than that of the traditional CS voice.The introduction of high-definition voice and video codes significantly improves the communication quality.VoLTE call setup duration has been significantly shortened compared to the traditional CS voice.Analyzing the factors in causing call setup delay of VoLTE was focused

and corresponding solutions about the VoLTE call setup delay optimization was put forward based on the signaling message in different stages

including paging

domain selection

resource reservation.
