telecommunication

This new book explains how telecommunications networks work. It uses straightforward language supported by copious block - schematic diagrams so that non-engineers and engineers alike can learn about the principles of fixed and mobile telecommunications networks carrying voice and data. The book covers all aspects of today's networks, including how they are planned, formed and operated, plus next generation networks and how they will be implemented. After an introductory chapter on telephony, the book briefly describes all of today's networks - PSTN, mobile, cable television, the Internet, etc. - and considers how they interconnect. Individual chapters then consider the principles, technologies and network structures relating to transmission, circuit switching, signalling and control, data (including voice-over-IP) networks, and mobile networks. The important subject of numbering and add...

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.

System Design for Telecommunication Gateways provides a thorough review of designing telecommunication network equipment based on the latest hardware designs and software methods available on the market. Focusing on high-end efficient designs that challenge all aspects of the system architecture, this book helps readers to understand a broader view of the system design, analyze all its most critical components, and select the parts that best fit a particular application. In many cases new technology trends, potential future developments, system flexibility and capability extensions are outlined in preparation for the longevity typical for products in the industry.
