Trang 16Second-generation (2G) mobile communication systems have enabled voice traffic to gowireless More important, however, have been the accompanying standardisation,compatibility and international transparency that were simply not available to tele-communications equipment of the previous analogue generation These features havehelped 2G systems to spread rapidly around the world, with very high cellular phonepenetration rates in many countries Cellular networks have enabled certain types ofcommunication to take place on a massive scale that previously were not possible orwere at least severely limited In the field of network building and expansion the mainadvances have been in planning the radio and transmission part of the network and inoptimising the processes and activities necessary to run existing operational networks.The third-generation (3G) system known as the Universal Mobile Telecommunica-tions System (UMTS) introduces very variable data rates on the air interface, as well asthe independence of the radio access infrastructure and the service platform For usersthis makes available a wide spectrum of circuit-switched or packet data services throughthe newly developed high bit rate radio technology named Wideband Code DivisionMultiple Access (WCDMA) The variable bit rate and variety of traffic on the airinterface have presented completely new possibilities for both operators and users,but also new challenges to network planning and optimisation
This book gives detailed descriptions of the radio network planning and optimisation
of UMTS networks based on Frequency Division Duplex (FDD) WCDMA technology
up to Release 5 of the 3GPP standardisation work – i.e., one main enhancement of thissecond edition is the inclusion of High-speed Downlink Packet Access (HSDPA) Onechapter is dedicated to the General Packet Radio System (GPRS) and Time DivisionDuplex (TDD) access mode of WCDMA The optimisation and Quality of Service(QoS) aspects have, however, a wider scope, than in (W)CDMA radio technology only.Chapter 1 introduces the history of cellular telecommunication and the changes inplanning and operation of such networks The challenges of network planning,optimisation and operation the operators and the wireless industry are facing on theway to 3G systems are introduced together with an outlook on future developments inthe area towards fourth-generation (4G) systems
Chapter 2 is in three sections The first introduces the general background of SpreadSpectrum Systems This is followed by a section related to the Third GenerationPartnership Project (3GPP), giving a panoramic view of the UMTS architecture,interfaces and functions that impact directly upon radio network planning HSDPAphysical layer properties are added as a new content in 3GPP Release 5 The third
Trang 17section discusses WCDMA-specific link performance indicators relevant for radionetwork dimensioning and planning.
Chapter 3 treats WCDMA radio network planning as a wider process that includesnetwork dimensioning with a special section for HSDPA, detailed planning, re-quirements for planning tools, algorithms used for calculations in WCDMA andoptimisation of the radio network plan The relationship between network dimension-ing, detailed network planning and dynamic network simulation is also discussed Thechapter closes with a discussion on cell deployment strategies with respect to thenumber of frequencies and the network structure This topic is presented as a casestudy
Chapter 4 covers Radio Resource Management (RRM) from the point of view ofradio resource utilisation, including power control, handover control, congestioncontrol (admission control, load control and packet scheduling), resourcemanagement and certain impacts of those functions upon network performance
A separate new section is devoted to RRM for HSPDA
In Chapter 5, first the background noise measurement along with measured resultsare introduced This part is followed by co-planning issues involving WCDMA and theGlobal System for Mobile communication (GSM), eventually other technologies Thethird part of the chapter describes the effects of intersystem interference, together withdynamic mobile station receiver properties on network performance The application ofthese methods and results is not, however, limited to the GSM–WCDMA scenario.Chapter 6 treats various coverage and capacity enhancement techniques (beam-forming, higher order receive diversity, transmit diversity, MIMO technology, masthead amplifiers, repeaters, rollout optimised configuration, sectorisation, etc.) Thechapter is based on an extensive set of case studies and contains practical examplesand conclusions
Chapter 7 introduces the concept of statistical optimisation and discusses 3GPPRelease 5 contributions in the management area including configuration and per-formance management issues Furthermore, the TeleManagement Forum enhancedTelecom Operations Map (TMF eTOM) model is briefly introduced A 3GPPmanagement model for the multi-vendor environment is addressed The managementsystem’s role in optimisation is presented and examples of management level productsand their capabilities are provided
Chapter 8 focuses on UMTS QoS mechanisms according to 3GPP Release 5 andexamples of practical realisations of the QoS capabilities in network elements areintroduced Furthermore, QoS as a differentiation enabler for operators is demon-strated and differentiation possibilities with the QoS concept are presented Theoptimisation loop expansion from the network layer to the service layer is described.Chapter 9 is devoted to advanced analysis methods and automated optimisation.Several new analysis methods for network performance analysis are introduced
In the area of automated optimisation examples of optimisation logic are providedfor the mobility management area, admission decision optimisation and capacityoptimisation in UMTS networks
Finally, Chapter 10 deals with two technologies that are different from the FDDmode of WCDMA The first is the GPRS branch in GSM technology This has broughtvariable rate packet data traffic into the air interface of originally circuit switched and
Trang 18single data rate service-oriented technology The second, the Time Division Duplex(TDD) mode of WCDMA, represents an interesting technology for high data rateindoor users Therefore, the radio performance properties of TDD mode areintroduced.
On the CD accompanying the first edition of this book we included a static radionetwork simulator implemented in Matlab1 together with detailed descriptions of thealgorithms used Most of the simulated scenarios are added, but not all the valuespresented can be reproduced exactly, since simulations have been done partly byusing earlier versions of the tool, which used slightly different strategies The tool isdelivered in its current version and state, and the authors do not give any warrantyconcerning the correctness of the code In addition, some coloured figures – in PDFformat – are included The simulator, its description and the figures can now be found
at www.wiley.com/go/laiho
The book is targeted at wireless operators, network and terminal manufacturers,university students, frequency regulation bodies and all those interested in radionetwork planning and optimisation, especially network systems RF engineeringprofessionals This book represents the views and opinions of the authors, which arenot necessarily those of their employers
