摘要
由于TD-LTE网络只部署PS域,因而无法进行语音业务。为了加快LTE商用的步伐而提出多种语音业务解决方案。CSFB技术作为TD-LTE语音技术的过渡而存在。本文介绍了TD-LTE网络中CSFallback技术实现语音业务的方法,重点阐述了CSFB技术的原理、系统架构及相关信令流程。
TD-LTE network only deploys PS domain, thus it is unable to support voice service. In order to speed up the pace of LTE commercial application, we put forward a variety of voice service solutions. CSFB is regarded as a interim solution of TD-LTE voice service. This paper introduces the method of TD - LTE network CS Fallback technology to support voice service, and focusing on the theory of CSFB technology, system architecture and signaling process related.
