**课程名称：** 3G、HSDPA+ 和 HSUPA+ **课程概述：** 本课程将深入探讨第三代移动通信技术（3G），与第二代通信技术（2G）进行对比，详细解析3G出现的必要性、其优势与劣势。课程内容涵盖： * **3G接入技术：** 重点讲解为何需要新的接入技术，以及在这一技术中面临的挑战和如何避免干扰。 * **3G网络架构：** 详细介绍网络中的各个节点，如基站、RNC（无线网络控制器）以及用户设备（UE）核心网及其节点的工作原理。 * **3G信道：** 区分逻辑信道、传输信道和物理信道，并讲解其各自的功能。 * **3G呼叫场景：** 分析UE与RNC之间在呼叫过程中交换的控制消息。 * **3G切换（Handover）场景：** 详细讲解从切换发起、测量报告、评估、准备到执行完成过程中，UE与RNC之间交换的控制消息及其含义。 * **3G协议栈：** 剖析逻辑层、传输层和物理层的各层工作原理及处理流程。 * **3G码树：** 介绍3G中的码类型、扩频因子以及不同扩频因子对应的数据速率。 * **HSDPA：** 讲解高速下行分组接入（HSDPA）的新特性。 * **HSUPA：** 讲解高速上行分组接入（HSUPA）的新特性。
in this course we will learn together about 3G as new technology over 2G we will learn all details about it and why we need a new technology over 2G , what is advantages and disadvantages about 3G we will learn a lot of details like - 3G Access Technique why we thought about new access technique over 2G access technique Challenges in this new access technique and how we avoid interference - 3G Network Architecture we will learn each node and how it works like base station and RNC radio network controller and user equipmentcore and its nodes- 3G Channelslogical channels transport channelsPhysical channels- 3G Call Scenario what are control messages sent between UE and RNC - 3G HO Scenariowe will learn which control messages between UE and RNC from Hand over initiation till doneAnd which each step meansmeasurement reportingevaluationpreparation execution - 3G protocol Stakewe will learn each layer of logical layer and transport layer and physicals layerhow each layer works and processing of it- 3G Tree of Codescodes types in 3G Spreading factorsdata rate of each spreading factor - HSDPAnew features of high speed downlink packet access -HSUPAnew features of high speed uplink packet access
