Beschreibung
The Universal Mobile Telecommunication System (UMTS) is the key third generation (3G) mobile communications technology. The UMTS standard consists of roughly 300 specification documents, so this book fulfills the real need for a good, current introduction to the area, based on the requirements laid out in the standard.
With full and up-to-date coverage of the standard, the book looks at the topic from the point of view of systems, and covers both the architecture and the techniques employed in the UMTS network. The introductory chapters cover the origins of UMTS and its relation to the other third generation technologies, while later chapters are more technical and describe different aspects of the standard, such as: architecture, structure of the radio interface, protocols used, importance of the GSM inheritance.
This book will be indispensable to developers, designers, project managers and other telecommunications professionals who need an easy-to-read overview of this important new technology and a comprehensive guide to the main points of the standard. It will also be useful for those attending courses on modern digital communications and 3G systems.
Sincethe beginning of the 1990s,cellular communication services have been enjoy ing an unprecedented level of development, made possible by the existence of the so-called second generation digital technologies, GSM (Global System for Mobile communication) being one of the most popular. These technologies, generally incompatible with each other, are the result of standards created at the start of the 1980s. After some years of evolution and successive improvements, these different standards have today reached the limits of their possibilities. In order to permit the creation of new services and to offer users real mobility on a global scale, it has become necessary to make a technological jump and cross the threshold to third generation cellular networks. Anumber ofpartners (telecom munications equipment suppliers and operators) have therefore been working together for some years to define the future technology, trying to reconcile the requirements of new services (high quality wireless Internet, multimedia, etc.) with the necessity of guaranteeing to users and network operators the smoothest possible transition to the new generation. Despite the unification efforts of the International Telecommunications Union, through its IMT-2000 program, there exist not one, but several third generation technologies, the main one being the Universal Mobile Telecommunication System (UMTS).Since January 1999,the 3GPP (Third Generation Partnership Project), in charge of the development of the UMTS standard, has carried out a substantial amount of work, whose concrete expression consists of several tens of thousands of pages of specifications spread over more than 300documents.
Contains fully up-to-date coverage of the new UMTS standard, which will be essential for anyone working in this area
The demand for advanced, high-speed multimedia mobile services has led to the development of a new 3rd generation of mobile communication systems. The Universal Mobile Telecommunication System (UMTS) is the key technology in this new generation, and is being launched commercially worldwide in 2002. It will play a major role in developing a mass market for high quality wireless multimedia communication systems which are forecast to be used by over 2 billion users worldwide by the year 2010.
