IMS Multimedia Telephony service has been standardized in 3GPP as the replacement of the circuit switched telephony service in cellular networks. The multimedia telephony service consists of several service components such as voice, video and text. &#8216;IMS Multimedia Telephony over Cellular Systems&#8217; provides a comprehensive overview of the service that will enable enriched telephony for mobile users. Enriched telephony fulfils the user&#8217;s desire to communicate in new ways, for example by sharing pictures and video clips. <p> In addition to an overview of the Multimedia Telephony service, the book focuses on the modern media processing methods, which allows the quality of the packet switched voice and video telephony not only to match but also possibly exceed the quality of circuit switched telephony. Such key components as adaptive jitter buffering and adaptation of conversational media are explained in detail. <p> <b>Key features:</b> <ul> <li> Detailed description of how Multimedia Telephony sessions are set-up and controlled <li> Analysis showing the capacity and quality of VoIP and Multimedia Telephony in cellular networks <li> Coverage of other IMS services such as PoC specified by 3GPP and OMA <li> Description of suitable QoS and radio bearers for Multimedia Telephony <li> Explanation of the modern radio interface, especially High Speed Packet Access, which is based on concepts such as link adaptation and fast hybrid ARQ </ul> <p> The possibilities for the current and future standards covered in this book make it an indispensable resource for engineers, designers and researchers in VoIP, telecommunication companies and universities teaching and conducting research in telecommunications. It will also be of interest to managers needing an in-depth knowledge of the engineering and key issues of this complex technology, and students aspiring to develop a career in this area.

karmano hy api boddhavyam boddhavyam ca vikarmanah akarmanas ca boddhavyam gahana karmano gatih The intricacies of action are very hard to understand. Therefore one should know properly what action is, what forbidden action is, and what inaction is. The Bhagvad Gita (4.17) This book is the outcome of the research contribution of Hanane Fathi towards her Ph.D. studies jointly with Shyam S. Chakraborty and Ramjee Prasad as - pervisors. To the best of the authors' knowledge, this is a ?rst book on voice over Internet protocol (VoIP) covering such a broad perspective as illustrated in Figure P.1. This book is a new, forward-looking resource that explores the present and future trends of VoIP in the wireless heterogeneous networks. This book also provides the discovery path that these network infrastructures are following from a perspective of synergies with the present systems and how they will pave the way for future systems. This book is intended for everyone in the ?eld of wireless information and multimedia communications. It provides different levels of material suitable for managers, researchers, network providers, and graduate students. We hope that all readers will experience the bene?ts and power of this knowledge. We have tried our best to make each chapter comprehensive and we cannot claim that this book is without errors. Any remarks to improve the text and correct the errors would be highly appreciated.
