Download Rapidshare Book IMS Multimedia Telephony over Cellular Systems

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. ‘IMS Multimedia Telephony over Cellular Systems’ provides a comprehensive overview of the service that will enable enriched telephony for mobile users. Enriched telephony fulfils the user’s desire to communicate in new ways, for example by sharing pictures and video clips.

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.

Key features:
Detailed description of how Multimedia Telephony sessions are set-up and controlled
Analysis showing the capacity and quality of VoIP and Multimedia Telephony in cellular networks
Coverage of other IMS services such as PoC specified by 3GPP and OMA
Description of suitable QoS and radio bearers for Multimedia Telephony
Explanation of the modern radio interface, especially High Speed Packet Access, which is based on concepts such as link adaptation and fast hybrid ARQ

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.

Download Rapidshare Ebook Self-Similar Processes in Telecommunications

For the first time the problems of voice services self-similarity are discussed systematically and in detail with specific examples and illustrations.

Self-Similar Processes in Telecommunications considers the self-similar (fractal and multifractal) models of telecommunication traffic and efficiency based on the assumption that its traffic has fractal or multifractal properties (is self-similar). The theoretical aspects of the most well-known traffic models demonstrating self-similar properties are discussed in detail and the comparative analysis of the different models’ efficiency for self-similar traffic is presented.

This book demonstrates how to use self-similar processes for designing new telecommunications systems and optimizing existing networks so as to achieve maximum efficiency and serviceability. The approach is rooted in theory, describing the algorithms (the logical arithmetical or computational procedures that define how a task is performed) for modeling these self-similar processes. However, the language and ideas are essentially accessible for those who have a general knowledge of the subject area and the advice is highly practical: all models, problems and solutions are illustrated throughout using numerous real-world examples.
Adopts a detailed, theoretical, yet broad-based and practical mathematical approach for designing and operating numerous types of telecommunications systems and networks so as to achieve maximum efficiency
Places the subject in context, describing the current algorithms that make up the fractal or self-similar processes while pointing to the future development of the technology
Offers a comparative analysis of the different types of self-similar process usage within the context of local area networks, wide area networks and in the modeling of video traffic and mobile communications networks
Describes how mathematical models are used as a basis for building numerous types of network, including voice, audio, data, video, multimedia services and IP (Internet Protocol) telephony

The book will appeal to the wide range of specialists dealing with the design and exploitation of telecommunication systems. It will be useful for the post-graduate students, lecturers and researchers connected with communication networks disciplines.
