课程名称：LTE和VoLTE基础知识：概述教程 课程概述：本课程由三星研究美国的Nishith Tripathi博士和弗吉尼亚州立大学的Jeff Reed教授主讲，提供了关于LTE（长期演进）和VoLTE（基于LTE的语音）的自学学习项目。课程通过一系列视频讲座，简要介绍LTE和VoLTE的技术概念，内容基于全球首部5G多媒体书籍《5G蜂窝通信：旅程与目的》。 课程内容： 第一部分 - LTE与网络架构简介 学习无线网络如何从第三代（3G）移动通信技术演进至4G LTE，同时了解LTE网络中的各种实体。 讲座1：LTE网络架构。全面描述LTE的网络架构及主要网络节点或元素的功能，包括无线网络和核心网络的覆盖内容。 第二部分 - LTE中的信息传输 了解信令消息和用户流量（如IP数据包）如何在无线网络中传输。 讲座2：LTE无线接口协议栈。讲解用户设备（UE）与LTE基站（eNB）之间的空中接口，介绍RRC、PDCP、RLC、MAC和PHY等协议的作用。 讲座3：LTE接入程序。在用户间交换流量（如视频或照片）之前，智能手机需要满足某些前提条件，接入程序就是其中之一，涉及互认证和默认承载的设置。 讲座4：LTE中的数据传输。讲解设备与网络之间在下行和上行中的数据如何传输。 第三部分 - LTE中的移动管理 LTE用户设备（UE）可能处于连接状态或闲置状态。该部分描述如何在连接模式下进行切换管理，以及闲置模式下的蜂窝重新选择、寻呼和跟踪区域更新。 讲座5：LTE中的切换。阐述LTE中的切换过程，网络如何控制UE的测量配置并管理UE的移动性。 讲座6：闲置模式活动。没有专用无线连接的用户设备在闲置模式下操作，讲解闲置模式下的操作，包括小区重新选择、寻呼和跟踪区域更新。 第四部分 - VoLTE基础 讨论如何在LTE网络中支持语音服务的基础知识。 讲座7：VoLTE的关键概念。LTE网络通过IMS（IP多媒体子系统）支持语音服务，讲解VoLTE的定义，以及包括注册和呼叫设置在内的VoLTE基础概念概述。 该课程为希望深入了解LTE和VoLTE技术的学习者提供了扎实的基础，适合技术人员和对此领域感兴趣的学生。
This self-paced LTE and VoLTE learning program from Dr. Nishith Tripathi (Samsung Research America) and Prof. Jeff Reed (Virginia Tech) provides a concise technical overview of LTE (Long Term Evolution) and VoLTE (Voice over LTE) through a series of video lectures. These lectures are based on the world's first 5G multimedia book: "5G Cellular Communications- Journey and Destination."Section 1- Introduction to LTE and Network Architecture. Learn about how the wireless networks evolve from a third-generation (3G) cellular technology to a 4G LTE. Also, find out what entities exist in an LTE network.Lecture 1: LTE Network Architecture.An overall network architecture of LTE is described with the job functions of major network nodes or elements. Both the radio network and the core network are covered.Section 2- Information Transfer in LTE. Ever wondered how a signaling message or user traffic such as an IP packet travels through a wireless network? This section explains the transfer of such information!Lecture 2: LTE Radio Interface Protocol Stack. The air interface between the UE and the LTE Base Station (i.e., eNdoeB or eNB) follows the rules of engagement defined by the radio interface protocol stack. This lecture explains the roles of the protocols such as RRC, PDCP, RLC, MAC, and PHY.Lecture 3: LTE Attach Procedure. Before you and I can exchange traffic such as a video or a photo using our smartphones, the smartphones need to meet certain prerequisites. The Attach procedure is one such prerequisite, where operations such as mutual authentication and default bearer setup occur.Lecture 4: Data Transfer in LTE. This lecture explains how data transfer occurs between the device and the network in the downlink and the uplink.Section 3- Mobility Management in LTE. An LTE UE may be in a Connected Mode or an Idle Mode. This section describes how handover is managed in the Connected Mode and how cell reselection, paging, and Tracking Area Updates are carried in the Idle Mode.Lecture 5: Handover in LTE. This lecture illustrates the process of handover in LTE, where the network controls the UE configuration for measurements and controls the UE mobility.Lecture 6: Idle Mode Activities. A UE without a dedicated radio connection operates in the idle mode. This lecture explains the idle mode operations such as cell reselection, paging, and Tracking Area Updates.Session 4- VoLTE Fundamentals. This section discusses the basics of how a voice service is supported using an LTE network.Lecture 7: Key Concepts of VoLTE. The LTE network supports voice services using the help of an IMS (IP Multimedia Subsystem) network. This lecture defines VoLTE and provides an overview of fundamental concepts of VoLTE including registration and call setup.
