**课程名称：** VoWiFi & WiFi Calling：架构、呼叫流程与IMS核心 **课程概览：** 本课程旨在为电信行业专业人士提供一项全面的实践指南，深入讲解VoWiFi（WiFi语音）及其如何与IMS核心和演进分组核心（EPC）无缝集成。我们将从VoWiFi的基本概念入手，阐述其与VoLTE和3G语音服务的区别，以及其在改善室内覆盖、通话质量和用户体验方面日益增长的重要性。 课程将详细剖析VoWiFi的架构，重点介绍UE、ePDG、PGW、AAA、P-CSCF、I-CSCF、S-CSCF和HSS等核心 元素的角色及其交互。您将深入了解IPSec隧道如何建立，默认和专用承载如何管理，以及在EPC和安全的VoWiFi路径之间如何进行承载映射。此外，我们将探讨IMSI、SIP URI、FQDN和APN等标识符如何用于路由和注册VoWiFi会话。 本课程将覆盖所有关键协议和接口，包括IKEv2、GTP-C/U和Diameter，以及SWu、S2b、SWm、SWx和S6b接口。您将通过真实世界的呼叫流程图和SIP信令序列，学习如何排查VoWiFi认证、隧道创建和呼叫建立过程中的常见问题。 完成本课程后，您将能够自信地分析、设计和优化移动网络中的VoWiFi服务。 **适用人群：** 任何从事IMS和分组核心网络工作的电信工程师、系统集成商或技术培训师。
Are you a telecom professional looking to master VoWiFi (Voice over WiFi) and understand how it integrates seamlessly into the IMS Core and Evolved Packet Core (EPC)? This course is your complete, practical guide to WiFi Calling - covering everything from basic concepts to advanced signaling flows, real-world deployment scenarios, and troubleshooting techniques.You'll begin by understanding what VoWiFi is, how it differs from VoLTE and 3G voice services, and why it's increasingly essential for improving indoor coverage, call quality, and user experience. From there, the course dives into VoWiFi architecture, detailing the roles and interactions of core elements like UE, ePDG, PGW, AAA, P-CSCF, I-CSCF, S-CSCF, and HSS.You'll gain in-depth knowledge of how IPSec tunnels are established, how default and dedicated bearers are managed, and how bearer mapping occurs between the EPC and the secure VoWiFi path. We'll also explore how identifiers like IMSI, SIP URI, FQDN, and APNs are used to route and register VoWiFi sessions.The course covers all critical protocols and interfaces including IKEv2, GTP-C/U, and Diameter across SWu, S2b, SWm, SWx, and S6b interfaces. You'll follow real-world call flow diagrams, SIP signaling sequences, and learn how to troubleshoot common issues in VoWiFi authentication, tunnel creation, and call setup.By the end, you'll be equipped to confidently analyze, design, and optimize VoWiFi services across mobile networks.This is a must-have course for any telecom engineer, system integrator, or technical trainer working with IMS and packet core networks.
