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)

"The authors provided an insightful discussion into a wealth of service possibilities that could be delivered by UMTS. This will potentially offer significant revenue opportunities and bring values to mobile operators and may also enable service enhancement with existing access technologies." (Dr. Stanley Chia, Director, Group R&D – US, Vodafone.)

Excerpt from UMTS Networks by Kaaranen
The world's first public GSM call was made on 1st July 1991 in a city park of Helsinki, Finland. That event is now regarded as the birthday of the 2nd generation mobile telephony. GSM has been an overwhelming success, which was difficult to predict at that early stage. In the past ten years GSM has become a truly global system for mobile communications. We now have cellular phone penetration rates exceeding 50% in many countries and reaching 80% in the Nordic countries.
Ten years later GSM has brought us onto the footstep of the 3rd generation mobile communications system - Universal Mobile Telecommunications System (UMTS). Again the first networks are being opened and new generation of fancy mobile phones will appear. By the end of February 2001 already 61 UMTS licenses were awarded to network operators in 16 different countries.
UMTS networks will introduce into wide area use a completely new high bit rate radio technology – wideband CDMA (Code Division Multiple Access). On the other hand the core network part of the UMTS system is firmly founded on the successful GSM network, which has evolved from circuit switched voice network into a global platform for mobile packet data services like short messaging, mobile web browsing and mobile email access.
The latest estimates show, that packet switching traffic in the mobile core networks will exceed circuit switching by 2005. This transition is enabled by the UMTS system, which makes it possible to the network operators to provide equally strong circuit-switched and packet-switched domains to meet the speed and capacity demands. Most voice and time-critical data services may still use circuit switching, while less time-sensitive data passes through the UMTS mobile packet core network.
One of the key promises made by the UMTS mobile computing and communications devices is the ability to deliver information to users almost anytime and anywhere. In UMTS the mobile phone is becoming a personal trusted device, a life management tool for work and leisure. Among the new possibilities for communication, entertainment and business are new kind of rich call and multimedia data services, which are fuelled by the mobility and personalization of users and their terminals. This is a book about UMTS networks as a 3rd generation platform for mobility and services. It aims to provide a comprehensive overview of the system architecture and its evolution and to serve as a guidebook to those who need to study the original 3GPP specifications. The contents of the book is divided into three parts:
First part consists of chapters 1 and 2, which serve as an executive summary to the UMTS system. Chapter 1 introduces the UMTS technical and service architecture and key system concepts. Chapter 2 is an illustrated story about mobile network evolution from 2nd generation GSM into the first UMTS release from the 3rd Generation Partnership Program (3GPP) and beyond that towards full-IP mobility networks.
Second part consists of chapters 3 to 8, which examine the radio access and core network in more details explaining the functions and services provided to the end users. Chapter 3 on UMTS radio communications provides the fundamentals on cellular radio which are necessary for understanding the WCDMA radio access system as part of the UMTS network. Chapters 4 and 5 present the functional split and system management aspects distributed among UMTS network elements within radio access and core network parts. Chapter 6 provides an overview on the UMTS user equipment focusing into those aspects, which are most visible to the rest of the UMTS network. In chapter 7 the UMTS network is examined as a network for services. The UMTS service capabilities (WAP, CAMEL, location based services etc) are first introduced as a value-added service platform and then application examples with different Quality of Service (QoS) characteristics are discussed. The advanced security solutions of the UMTS network are then discussed in Chapter 8.
The remaining chapters 9 and 10 form the third part of the book. In these chapters we take a protocol-oriented view describing the system-wide interworking between the different architectural elements. Chapter 9 first elaborates the basic UMTS protocol architecture and then introduces the individual system protocols one by one. Chapter 10 returns to the network-wide view by proving selected examples of system procedures, which describe how the transactions are carried out across the UMTS network interfaces under the co-ordination of the system protocols.
At the footstep of the 3rd Generation mobile communications the success of the UMTS will come from the thousands of leading system and software engineers, content providers, application developers, system integrators and network operators. We wish this book will help all of them to reach their targets and let them enjoy and benefit from the UMTS networking environment.
