Features: This book is a dedicated work on IMS, explaining why IMS is needed and its historical development, and provides a detailed introduction to the control plane, media flow plane, and business establishment based on IMS. It includes numerous network architecture diagrams and message processing flows, offering excellent guidance for learning and understanding IMS. This book is suitable for a broad range of engineering technicians engaged in communication product development and network planning and design, as well as serving as a reference for students and faculty in communication and computer science at higher education institutions. The book not only provides a macroscopic description of the overall principles, historical development, and standard progress of IMS but also delves into micro-level analyses of the specific network architecture, protocol applications, and message processing flows of the signaling plane and media plane, while also offering examples of SIP-based services. Part briefly outlines the goals, development process, and architecture of IMS. The second part describes the IMS signaling plane, including various protocols such as SIP (Session Initiation Protocol), SDP (Session Description Protocol), Diameter, IPSec, and COPS (Common Open Policy Service). The third part describes the IMS media plane. The final part provides examples of IMS services, such as Presence, instant messaging, and PTT. This book is suitable for a broad range of engineering technicians engaged in communication product development and network planning and design, as well as serving as a reference for students and faculty in communication and computer science at higher education institutions.
