Coursera 上的《精通 Wi-Fi 语音通话（VoWiFi）》课程 (Mastering Voice over Wi-Fi (VoWiFi) Wi-Fi Calling بالعربي) 旨在提供对 Wi-Fi 语音通话（VoWiFi）的全面、端到端的深入理解。这门课程对于电信工程师（核心网、IMS、接入网或无线网）以及希望专攻 LTE/IMS/5G 技术的学生都非常有价值。 课程内容涵盖了 VoWiFi 的基本原理、业务驱动因素和优势，并深入讲解了其在 IMS 架构下的工作机制。课程将详细介绍诸如 ePDG、AAA 服务器、PGW/UPF 和 IMS 核心网等关键网络元素的角色，以及它们在注册、呼叫建立、安全（IPSec/EAP-AKA）和承载建立过程中的作用。 通过真实的通话流程（call flows）、Wireshark 跟踪（traces）和故障排除案例，学员将学会如何分析注册失败、呼叫中断和 QoS（服务质量）问题。此外，课程还将探讨关键绩效指标（KPIs）、部署模式（如 S2b 和 LBO）以及如何优化以提升语音质量和用户体验。 学完本課程，学员將能夠： * 理解 VoWiFi 如何與 IMS 和 EPC/5GC 整合。 * 配置和故障排除 VoWiFi 服務。 * 自信地分析消息跟踪和通话流程。 * 將所學知識應用於實際運營商場景。 这门课程充满了实践性的见解、技术清晰度和现实世界的关联性，是任何从事 IMS 或语音服务的电信专业人士的必备之选。
Voice over Wi-Fi (VoWiFi)-also known as Wi-Fi Calling-is no longer just a niche feature. It's a critical service in modern telecom networks, especially in areas with poor indoor cellular coverage. This course is designed to give you a complete, end-to-end understanding of how Wi-Fi Calling works within IMS-based architectures, how it's deployed in real operator environments, and how to troubleshoot common issues.Whether you're a telecom engineer working in Core, IMS, Access, or Radio, or a student aiming to specialize in LTE/IMS/5G technologies, this course will provide the technical depth and practical examples needed to confidently work with VoWiFi services.We'll start with the fundamentals of VoWiFi, including the business drivers and benefits. Then, we'll deep-dive into network elements like the ePDG, AAA server, PGW/UPF, and IMS Core components-explaining their roles in registration, call setup, security (IPSec/EAP-AKA), and bearer establishment.Through real-world call flows, Wireshark traces, and troubleshooting cases, you'll learn how to analyze registration failures, call drops, and QoS issues. You'll also explore KPIs, deployment models (like S2b and LBO), and how to optimize for better voice quality and user experience.By the end of this course, you'll be able to:Understand how VoWiFi integrates with IMS and EPC/5GC.Configure and troubleshoot VoWiFi services.Analyze message traces and call flows with confidence.Apply your knowledge to real operator scenarios.This course is packed with practical insights, technical clarity, and real-world relevance-a must-have for any telecom professional working in IMS or voice services.
