Next Generation Network Services - Technologies and Strategies

a Next Generationa refers to the new technologies and services that telecommunications operators will have at their disposal as they create new 3G networks where voice and data converge and which are based on packet switched rather than circuit switched telephony. Providing a much needed overview of the latest communication technologies and describing the influences of the so--called "next generation" networks on telecommunication operatorsa environments, this text begins with a very brief history of telecommunications, and explains how the advent of the internet has changed the way people think about communications. The book is split into three parts: 1. Technologies: Describes the different technologies that are influencing the change from circuit switched to packet switched telephony. Covers Media Gateway Control (MEGACO), application service provision, models for management, mobile and fixed technologies such as Digital Subscriber Line and GPRS. 2. Services: Explains the new services that are made possible by the new technologies, and how they improve on current services. This section also brings in important techniques from software engineering (such as application frameworks) and shows how they may be used to create flexible network architectures. 3. Going Forward: The effects of all the recent changes on the telecommunications operators, and how it is possible to capitalise on this. Roadmaps provide a picture of the state of the industry in six months, one year and three yearsa time. aeo Presents overviews of all the new technologies and services, demonstrating how they interrelate aeo Written by a consultant with a wide experience of installing networks, as well as advising on network strategies for companies including Marconi, BT, IPL, Mercury, BTCellnet and Cable & Wireless aeo Coverage includes Internet connectivity, e--commerce, call centres, application service provision, UMTS, WAP, billing, security and directory enable networks A leading edge reference resource for telecommunications network managers, network strategists and designers.
