The IP Multimedia Subsystem (IMS) is the basic network architecture for Next Generation Networks (NGN) which is intended to bridge the divide between the traditional circuit switched and packet switched networks, thereby providing a single network capable of providing all service offerings. IMS is based on the IP infrastructure and it enables the convergence of data, speech and video on the same network platform. The IMS forms the basis of Fixed Mobile Convergence (FMC), where fixed-line operators are striving to provide mobile access and mobile operators are trying to provide fixed access. This is done to provide both services to a customer in a single device. The IMS is based on Session Initiation Protocol (SIP), which is a text-based protocol. The IMS will generally create additional signaling traffic in the IP based networks, so there is a need to take necessary precautions to minimize the signaling overload. This research is based on how the performance of the IMS can be improved by optimization of SIP as well as IMS elements. An analysis and characterization of the signaling traffic generated by IMS has been performed and how the signaling traffic can be reduced by the compression of SIP using the Burrows Wheeler Transform (BWT) has been explored. The queuing models of the IMS have been formulated and the mathematical approach has been used to find the impact of implementing the Hyper-Threading technology on the IMS Elements.

Take Part in the Future of Wireless/Wireline Convergence The IP multimedia subsystem (IMS), established as the foundation for future wireless and wireline convergence, is the bedrock that will facilitate easy deployment on new, rich, personalized multimedia communication services that mix telecom and data services. Designers, planners, and researchers of communication systems will need to make full use of the technology occurring with this convergence if they want to be the ones providing end users with new and efficient services that are as cost-effective as they are innovative. To provide researchers and technicians with the tools they need to optimize their role in this communication revolution, the IP Multimedia Subsystem (IMS) Handbook presents all the technical aspects of the IMS needed to support the growth of digital traffic and the implementation of underlying networks. This guide covers everything from basic concepts to research-grade material, including the future direction of the architecture. Organized in three sections, the book brings together the technical savvy of 50 pioneering experts from around the world, providing complete coverage of relevant concepts, technologies, and services. Learn How IMS Will Speed Innovation Filling the gap between existing traditional telecommunications and Internet technologies, IMS has led to an environment in which new services and concepts are introduced more quickly than ever before, such as reusable service components and real-time integration. The technology promises to be a cost-effective evolutionary path to future wireless and wireline convergences that will meet next-generation service requirements.

The IMS: IP Multimedia Concepts and Services in the Mobile Domain, Second Edition, builds 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, developes, test engineers and university students.

IP Multimedia Subsystem (IMS) is envisioned as the solution for the next generation multimedia rich communication. Based on an open IP infrastructure, IMS enables access independent convergence of data, speech, video and mobile network technologies. Session Initiation Protocol (SIP) is the signaling protocol of choice for IMS. In this thesis, we propose service models for IMS networks with utility functions. These service models act as control mechanisms to optimize network properties. We analyze the IMS network based on the SIP signaling delay and predict performance trends of the network. Our focus is on the formulation of queueing models for the IMS network and characterization of the SIP server workload. This approach of theoretical evaluation combined with realistic performance characterization can be used for designing IMS networks with optimal performance. Our analysis is based on a careful study of real-life SIP network traffic.

Recent spectacular achievements in wireless, mobile, and sensor networks have dramatically changed our lives in many ways. However, the rapid evolution of wireless systems not only promises increased functionality, reliability, availability, and security, as well as putting a wide variety of new services at the users’ disposal ? it also creates a number of design challenges that our research community is now facing. Scientists and engineers need to come up with, and promptly implement, novel wireless network architectures, while system operators and planners rethink their business models and attend to the growing expectations of their customer base. To provide a suitable forum for discussion between researchers, practitioners, and industry representatives interested in new developments in the respective research area, IFIP WG 6. 8 launched three separate series of conferences: MWCN (Mobile and Wireless Communications Networks), PWC (Personal Wireless Communications), and WSAN (Wireless Sensor and Actors Networks). In 2008, MWCN and PWC were merged into the IFIP Wireless and Mobile Networking Conference (WMNC 2008), held in Toulouse, France, from September 30 to October 2, 2008. MWNC 2008 and PWC 2008 topics were subsequently revised with a view to covering the whole spectrum of hot issues in wireless and mobile networking. As a result, IFIP WG 6. 8 decided to add WSAN as another WMNC track.
