The IMS: IP Multimedia Concepts and Services, Second Editionbuilds on the success of the previous best-selling edition, providing comprehensive coverage of IMS its concepts, architecture, protocols and functionalities with a wealth of new and updated material. Mobile telephony with the current technology has been hugely successful and demonstrates the immense value of communicating with peers while being mobile, and with increasingly available smarter multimedia terminals, the communication experience will be something more than just exchanging voice. These multimedia terminals need IP multimedia networks. Hence the Third Generation Partnership Project (3GPP) has developed a standard for SIP-based IP multimedia service machinery known as The IMS (IP Multimedia Subsystem). This completely up-to-date and informative guide explains everything you need to know about it.

Key features of the Second Edition include:

• Two new chapters on push-to-talk over cellular and group management
• Additional new material includes: fixed and mobile convergence, interworking between IPv4 and IPv6 in the IMS, combined circuit-switched and IMS services (combinational services), IMS security and alternative session establishment procedures
• More coverage of the benefits of IMS, particularly with regard to its role in fixed-mobile convergence
• Special emphasis on services, featuring more detailed descriptions of presence, messaging, group management and push-to-talk over cellular (conferencing)
• Updates on Third Generation Partnership Project Agreement (3GPP) Release 6 level
• New examples and case studies, including a variety of scenarios, how to handle multiple terminals and end-user preferences

Written in a manner that allows readers to choose the level of knowledge and understanding they need to gain about the IMS, this volume will have instant appeal to a wide-ranging audience including marketing managers, research and development engineers, network engineers, developers, test engineers and university students.
