**课程名称：** 5G新空口（NR）上的语音（VoNR）入门 **课程概述：** 本课程旨在介绍独立组网（Standalone）5G网络中的语音服务，即语音过新空口（Voice over New Radio），简称VoNR。随着5G网络的不断部署，运营商正致力于如何在5G环境中支持语音通信。与4G类似，5G语音服务同样依赖于IP多媒体子系统（IMS）的部署。 课程将从以下几个方面展开： 1. **VoNR的概念与驱动因素：** 介绍VoNR的核心概念、发展背景和主要驱动力，以及相关标准组织（如3GPP）在该领域的工作。 2. **VoNR的架构设计：** 阐述VoNR部署的关键架构要求，包括5G新空口接入网、IMS呼叫控制网络以及连接两者的策略与计费控制（PCC）框架。 3. **初始接入与注册流程：** 探讨设备如何获得语音服务的初始接入，包括5G接入过程和IMS的注册流程。 4. **呼叫建立过程：** 详细介绍VoNR的呼叫建立细节，涵盖所使用的编解码器、媒体数据包化以及会话发起协议（SIP）消息交换的高层概览。 5. **与其他网络的互通：** 重点关注VoNR与现有语音网络（如传统的语音服务）的互通，以及不同场景下的切换，例如Wi-Fi通话和EPS回落（EPS Fallback）。
As the rollout of Standalone 5G continues, operators are turning their attention to how voice services will be supported in a 5G environment. Like 4G, the answer lies in the deployment of IMS and as such, this course seeks to outline the main aspects of IMS based voice services over 5G New Radio, termed Voice over New Radio or VoNR.The course will initially focus on setting the scent for VoNR, establishing the main concepts and drivers, including the work undertaken by the key standards bodies. Next, the course will outline the key architectural requirements for a VoNR deployment, covering the essential elements of the 5G New Radio access network, the IMS Call Control network and the Policy and Charging Control framework connecting the two. Initial procedures will then be discussed, outlining the steps a device needs to take in order to gain initial access to their voice services, including 5G access and IMS registration. Next, call establishment aspects will be examined, ranging from the codecs and media packetization used, through to a high level overview of the SIP message exchange. Finally, interworking with alternative voice networks will be covered, focussing on "legacy" voice services, as well as handovers, Wi-Fi Calling and EPS Fallback.
