Third edition of this best-selling guide to IMS: fully revised, and updated with brand new material

The IMS (IP Multimedia Subsystem) is the technology that merges the Internet with the cellular world. It makes Internet technologies such as the web, email, instant messaging, presence, and videoconferencing available nearly everywhere at any time.

The third edition of this bestselling book is fully updated and provides comprehensively expanded content, including new chapters on emergency calls and on Voice Call Continuity (VCC). As well as this, The 3G IP Multimedia Subsystem (IMS) presents updated material including a comprehensive picture of Session Initiation Protocol (SIP) as well as its applicability to IMS. As most of the protocols have been designed in the IETF, this book explains how the IETF developed these protocols and describes how these protocols are used in the IMS architecture.

This is an indispensable guide for engineers, programmers, business managers, marketing representatives and technically aware users who want to understand how the IMS works and explore the business model behind it.

• New chapters on emergency calls, Voice Call Continuity (VCC), service configuration (XCAP, XDM), and conferencing
• Fully updated throughout, including Policy and Charging Control (PCC), QoS, Presence, Instant Messaging, Multimedia Telephony Services, and Push-to-talk over Cellular (PoC)
• Describes the IP Multimedia Subsystem from two different perspectives: from the IETF perspective, and from the 3GPP perspective.
• Provides details on the latest policy technology and security architecture
• Written by experienced professionals in the field.

About the Author:

Gonzalo Camarillo leads the Advanced Signalling Research Laboratory of Ericsson in Helsinki, Finland. He is an active participant in the IETF, where he has authored and co-authored several specifications used in the IMS. In particular, he is a co-author of the main SIP specification, RFC 3261. In addition, he co-chairs the IEFT SIPPING working group, which handles the requirements from 3GPP and 3GPP2 related to SIP, and the IETF HIP (Host Identity Protocol) working group, which deals with lower-layer mobility and security. He is the Ericsson representative in the SIP Forum and is a regular speaker at different industry conferences. During his stay as a visitor researcher at Columbia University in New York, USA, he published a book entitled “SIP Demystified”. Gonzalo received an M.Sc. degree in Electrical Engineering from Universidad Politecnica de Madrid, Spain, and another M.Sc. degree (also in Electrical Engineering) from the Royal Institute of Technology in Stockholm, Sweden. He is currently continuing his studies as a Ph.D. candidate at Helsinki University of Technology, in Finland.

Miguel A. García-Martín is a Senior Expert in IP Multimedia technologies at Ericsson in Helsinki, Finland. He is an active participant of both IETF and 3GPP. In the IETF, he has authored and co-authored several specifications related to the IMS. In 3Gpp, he has been a key contributor to the development of the IMS standard. Miguel is also a regular speaker at different industry conferences. Miguel received a B. Eng. Degree in Telecommunications Engineering from Universidad de Valladolid, Spain.
