**课程名称：** VoLTE & CSFB **课程概述：** 本课程深入探讨了在纯分组交换的LTE网络中实现语音和视频通话的解决方案。鉴于语音通话仍是移动运营商的主要收入来源，课程重点介绍了两种关键技术：电路交换回落（CSFB）和LTE语音（VoLTE）。 课程为学习者提供了对 **SIP协议** 和 **IMS（IP多媒体子系统）网络** 的扎实理解。IMS网络被详细阐述为处理语音和视频多媒体会话的核心网络，其能够接入3G、4G、Wi-Fi和固定网络等多种接入方式。课程将详细介绍IMS的主要组成部分及其功能。 在深入讲解VoLTE解决方案及其特性之余，课程也将简要介绍 **WiFi语音（VoWiFi）**，并将其视为VoLTE的扩展。 最后，课程将对用于评估移动网络语音服务性能的关键绩效指标（KPI）进行清晰的阐述。 **先修知识要求：** 学习者需要具备LTE网络结构及节点基本功能的背景知识。
LTE network is a pure packet switching network that is used for data communication and does not support circuit switching communication that is designed to carry voice calls. Voice calls are still considered the main revenue stream for mobile network operators, so there is a need to find solutions to provide voice and video calls over LTE network. This course aims to give a very good background in voice solutions in LTE networks which are circuit Switching Fall Back (CSFB), Voice over LTE (VoLTE), and Voice over WiFi (VoWiFi).The course gives you a very good background in SIP protocol and IMS networks and focuses on VoLTE solution and features.IMS network is the core network that responsible for executing multimedia sessions (voice and video) and can be connected to any access network like 3G, 4G, Wifi, and fixed networks. the course addresses the main IMS elements and function of them.In addition to VoLTE and CSFB the course give brief introduction about Voice over WiFi (VoWiFi) which considered as an extension to VoLTE.At last the course gice a good illustration about the common key performance indicators that used to evaluate the performance of voice service over the mobile network.You have to have a background on LTE network structure and the basic functions of its nodes.
