摘要

话音业务是移动通信网为用户提供的基础业务之一。在LTE时代，有多种承接2G/3G话音业务的方案，VoLTE是未来的主流方案。本文研究了VoLTE解决方案，并结合3GPP标准梳理了VoLTE网元架构和业务流程，分析了VoLTE方案如何保证业务连续性的问题，研究了VoLTE中的QoS保障关键技术以及实际商用VoLTE的网络和终端的要求，以期给运营商的VoLTE网络建设和业务开展提供一定的参考。

Abstract

Voice service is one of the basic services that the mobile internet carrier provides for its users. There are severa1 schemes to carry on the voice service in LTE era. The VoLTE scheme was focused on and had been studied both in theoretica1 and implementation views. Based on the 3GPP standards，the key technologies of VoLTE had been clarified，and the network architecture was also studied. Specifica11y，the interoperability between VoLTE and the 1egacy networks was analyzed to guarantee the continuity of service. Additiona11y，suggestions were given for the VoLTE development and business conducting.
