2G/GSM and 3G/UMTS are key mobile communication technologies, chosen by more than 2 billion people around the world. In order to adapt to new services, increasing demand for user bandwidth, quality of service and requirements for network convergence, major evolutions are introduced in 3G network standard. Evolved Packet System (EPS) presents the EPS evolution of the 3G/UMTS standard introduced by the 3rd Generation Partnership Project (3GPP) standard committee. This new topic is looked at from a system perspective, from the radio interface to network and service architecture. Hundreds of documents being issued by Standard organisations are summarised in one book to allow the reader to get an accessible comprehensive view of EPS evolution. Proposes a system view of Evolved UMTS, from the radio to Core and service architecture Gives a comprehensive and global view of the system that technical specifications do not provide Describes the new system as well as the inheritance and migration from 2G/GSM and 3G/UMTS Written by experts in the field who specialise in two complementary but very different technical domains (i.e. "radio interface" and "network architecture") Contains many figures and examples for better understanding. This book is essential for industry professionals in the telecommunication business, telecommunication system architects and designers, product manufacturers and operators and postgraduate students.

This textbook provides students with a sound foundation in the concepts and applications of mobile computing. It discusses all the relevant topics in mobile computing in a clear and straightforward style. The book begins with an introduction to the subject and then moves on to describe the fundamentals of wireless communication including a brief description of different modulation techniques. The text includes coverage of second generation (2G) cellular network together with its two important implementation standards GSM & IS-95; it also discusses WLL and WLAN. In addition, it presents a variety of data services available in the domain of mobile computing with other relevant issues. Finally, it gives a brief on UMTS, a representative of the third generation (3G) of cellular networks. The fundamental tenets of mobile computing, such as mobility management, channel assignment, protocols at air interface, and system design are carefully covered for all categories of wireless networks described here. A perfect balance between theoretical aspects of mobile computing and its implementation standards has been maintained throughout the book. Many examples and exercises are included, which will help students prepare for examinations. The book is intended primarily for students of B.E./B.Tech. of Computer Science and Engineering, Information Technology, Electronics and Communication Engineering, and related disciplines. It will also be useful to the students of BCA/MCA and B.Sc./M.Sc. (Computer Science/Electronics).

Highly regarded as the book on the air interface of 3G cellular systems WCDMA for UMTS has again been fully revised and updated. The third edition now covers the key features of 3GPP Release 6 ensuring it remains the leading principal resource in this constantly progressing area. By providing a deep understanding of the WCDMA air interface, the practical approach of this third edition will continue to appeal to operators, network and terminal manufacturers, service providers, university students and frequency regulators. Explains the key parts of the 3GPP/WCDMA standard Presents network dimensioning, coverage and capacity of WCDMA Introduces TDD and discusses its differences from FDD Key third edition updates include: Covers the main 3GPP Release 6 updates Further enhances High Speed Downlink Packet Access (HSDPA) chapter with a number of new simulation results Explains High Speed Uplink Packet Access (HSUPA) study item Introduces the new services including their performance analysis : Push-to-Talk over Cellular (PoC), streaming, See What I See (SWIS) and multiplayer games Presents a number of new WCDMA field measurement results: capacity, end-to-end performance and handovers Includes completely updated antenna beamforming and multiuser detection sections featuring new simulation results Introduces TD-SCDMA and compares it to Release TDD

UMTS (Universal Mobile Telecommunication System) bezieht sich auf die 3. Generation mobiler Kommunikationssysteme. Die Mobilkommunikation der Zukunft wird unseren Alltag und unsere Arbeit nachhaltig verändern: Sie gibt uns die Möglichkeit, zu jeder Zeit, an jedem Ort und auch während der Fahrt zu kommunizieren und bietet verschiedene Dienstleistungen an, die bislang nur Festnetznutzern zur Verfügung standen. Die Mobilsysteme der 3. Generation (IMT-2000) werden ab 2001 in Japan und ab 2002 in allen übrigen Ländern auf den Markt kommen. Bis Ende 2003 wird es mehr als eine Milliarde mobiler Terminals weltweit geben.

Can you afford not to read this book?........ The Universal Mobile Telecommunication System (UMTS) offers a consistent set of services to mobile computer and phone users and numerous different radio access technologies will co-exist within the UMTS system’s core network – security is, therefore, of the utmost importance. UMTS Security focuses on the standardized security features of UMTS and brings together material previously only available in specifications, design documents and presentations in one concise form. In addition, this unique volume also covers non-standard implementation specific features that allow differentiation between operators and manufacturers. Describes the security solutions specified for UMTS Provides a comprehensive presentation of the UMTS security specifications and explains the role of the security functionality in the UMTS system Presents the UMTS security system in its totality from the theoretical background through to the design process Discusses the new security features included in Release 4 and 5 By providing a unified treatment of the security services provided by the UMTS system, this volume will provide invaluable information and have instant appeal to planners, constructers and implementers of UMTS networks, and developers and analysts of application oriented security services that make use of UMTS communication networks. It will also be of considerable interest to postgraduates and researchers of modern communication security technology.

UMTS Networks provides an outstanding description of 3rd generation UMTS mobile networking technology. It discusses both the core network evolving from the globally successful GSM/GPRS system and the radio access network based on newly emerged Wideband CDMA (Code Division Multiple Access) technology. UMTS networks will provide a platform for mobile packet data and multimedia services bringing new business opportunities to existing and greenfield cellular operators, manufacturers and internet service and content providers. Written by a group of experts in mobile networking, this practical approach will have wide-ranging appeal to system, software and field engineers and technical managers in cellular operator, manufacturer and service provider companies as well as students of telecommunications engineering and computer networks. "The 3rd generation research and standardisation has been a major challenge to the Nokia R and D engineers, who togther with their competent colleagues from around the world telecom community have put together the UMTS network specifications, which will bring the mobile communications into the era of personal, pocket-sized multimedia." Prof., Dr. Juhani Kuusi, SVP, Head of Nokia Research Center UMTS networks are introduced in three parts: 1. Explains the overall system design and describes the network elements and functions of a complete UMTS network. It also illustrates how mobile networks evolve from 2nd generation GSM into first UMTS release and beyond towards full-IP mobility networks 2. Examines the radio access and core network in further detail explaining the functions and services provided to the end users. This part creates a solid understanding of how user location is managed, security is guaranteed, circuit bearers are established and released, packet traffic flows are maintained and terminal handovers are carried out. 3. Increases the reader's knowledge by explaining how the previous functions are distributed throughout the network by means of communication protocols providing references to the original UMTS standards published by the 3rd Generation Partnership Program (3GPP)
