课程名称：5G O-RAN（开放无线接入网）：架构、程序与应用案例 课程概述：O-RAN（开放无线接入网）通过将无线接入网（RAN）拆分成各个组件部分，为电信运营商提供了服务创新和灵活性的新的途径。O-RAN标准向所有第三方软件开发者开放，允许他们开发新型服务并在RAN智能控制器（RIC）上进行创新，构建xApps和rApps。这使得电信运营商能够使其网络成为企业和消费者应用的更有价值的资源。O-RAN的一个主要优势是能够使电信运营商避免供应商锁定，通过开放标准的完全解耦的RAN替代供应商专有接口。自动化将在管理解耦的、云原生RAN功能的生命周期中起到关键作用。O-RAN可以通过持续集成/持续交付（CI/CD）的方式演进网络，降低网络的部署和运营成本，而不是通过代际投资周期。该课程涵盖了全面理解O-RAN技术所需的重要主题，并讨论了O-RAN联盟的相关标准，以描述O-RAN的架构和工作原理，以及O-RAN的开放接口。 课程内容： 第1部分：介绍 - 5G网络的主要组件 - 开放RAN的设计目标 第2部分：向开放RAN的演进 - 传统基站架构 - 现代基站的演进 - 向虚拟化RAN（vRAN）的演进 - 从虚拟化RAN（vRAN）向开放RAN的演进 - 分布式RAN与集中式RAN的区别 - 集中式RAN与云RAN的区别 - 5G开放RAN的路径：横向解耦 第3部分：RAN分割-逻辑视图 - 不同RAN功能分割 - RAN分割选项1、2、6、8 - 以开放RAN增强CPRI（e-CPRI）协议 第4部分：O-RAN架构概述 - 开放RAN与O-RAN的区别 - 控制平面和用户平面的解耦 - O-RAN联盟架构中引入的实体和接口 - O-RAN节点的聚合选项 - O-RAN控制回路 - O-RAN生态系统中的主要实体 第5部分：O-RAN的虚拟化技术 - 虚拟化的演进：物理网络功能（PNFs）与虚拟网络功能（VNFs） - 作为VNFs的单体应用 - 云原生网络功能-分布式应用 - O-Cloud部署选项 - O-RAN中的DEVOPS CI-CD网络自动化以降低CAPEX和OPEX 第6部分：详细O-RAN架构 - 服务管理与编排（SMO） - 非实时RIC（non-RT RIC） - JSON格式示例 - A1策略格式及示例 - 接近实时RIC集中式与分布式设计 第7部分：O-RAN流量引导用例 - O-RAN流量引导（TS）应用示例 - 传统流量引导问题 - O-RAN使用流量引导的优势 - 流量引导所需数据（KPI）收集 - 非RT RIC在流量引导中的角色 - 接近RT RIC在流量引导中的角色 - E2节点在流量引导中的角色 - 流量引导示例场景 第8部分：5G O-RAN中的网络切片 - 网络切片的定义 - 5G网络切片示例 - 单网络切片选择辅助信息（S-NSSAI） - 网络切片子网实例（NSSI） - 网络切片管理模型：CSMF、NSMF、NSSMF - 网络切片模板（NST） - 开放网络自动化平台（ONAP）架构 - 基于ONAP的O-RAN网络切片架构 - 使用ONAP创建网络切片实例的程序 第9部分：其他O-RAN用例 - 用例：NSSI资源分配优化 - NSSI资源分配优化步骤流程图 - 用例：基于航迹的动态无人机无线资源分配 - 基于航迹的动态无人机无线资源分配步骤流程图 通过本课程，学习者将能够全面理解O-RAN技术的关键概念及其在5G网络中的应用。
O-RAN (or Open RAN) opens new avenues of service innovation and agility for telcos by breaking the Radio Access Network (RAN) into its component parts, each of which can be separately reconfigured. O-RAN standards are freely accessible to all third-party software developers, who can develop new types of services and innovate on the RAN Intelligent Controller (RIC) by building xApps and rApps. This enables telcos to make their networks a much more relevant resource for both enterprise and consumer applications.Arguably the open RAN's biggest claim is the potential to enable telcos to avoid vendor lock-in by replacing vendor-proprietary interfaces with a fully disaggregated RAN based on open standards.Automation will be key to managing the lifecycle of disaggregated, cloud-native RAN functions. O-RAN can bring down the network deployment and operation cost by evolving the network in a continuous integration/ continuous delivery (CI/CD) manner rather than through generational investment cycles. This course covers all the important topics that are required to have a good and comprehensive learning of the O-RAN technology. The relevant standards of the O-RAN alliance have been discussed to describe the O-RAN architecture and working, as well as the O-RAN open interfaces.
