摘　　要：语音业务是移动通信中最重要、最基本的通信业务。对3GPP提出的使用CS回退(CSFallBack)技术实现LTE/EPC部署中的语音业务方案进行了研究,分析了其网络架构和CS语音的实现过程,并对其他两种LTE运营商可能采用的语音实现方法进行了分析。Voice service is always the most important and fundamental communication application in mobile communication. In this article, CS FallBack technology which can be used to realize voice service in the LTE/EPC has been researched, and the network architecture as well as CS voice call procedure has been analyzed. Meanwhile, the alternative two voice service implementation methods which may be deployed by LTE operators are also analyzed.
