    • Agenda • Introduction • Evolution from GSM to UMTS • UMTS Architecture • UMTS Protocols • UMTS Services • UMTS Venders • Terminal Availability • Summary 2
    • In roduct (1 ) t ion /4 1G – Introduced in late 1970s and early 1980s – Typical Systems: AMPS, NMT and TACS – Services: Aanalog voice and basic mobility – Problems: incompatability, limited capacity 3
    • In roduct (2 ) t ion /4 2G – Development started in 1982 – First GSM network was opened in Finland in 1991 – Typical Systems: GSM, D-AMPS, PDC and CDMA – Services: Speech transmission, data transmission and supplementary services – Problems: Incompatability, not fully globalized 4
    • In roduct (3 ) t ion /4 3G – Development: • Research on the suitability of CDMA and TDMA for 3G started in 1991 • 3GPP was created in Denmark in 1998, it specifies UMTS standards – Target: Globalization of mobile communicaitons – Requirements: • Worldwidely valid system having standardized open major interfaces • Clearly added value to GSM and backward compatible at least with GSM and ISDN • Must support multimedia • Worldwidely available generic radio access providing wideband capacity • Services must be independent from radio access technology • Network infrastructure must not limit the services to be generated 5
    • In roduct (4 ) t ion /4 3G (continued) – UMTS – Universal Mobile Telecommunications System: The European vision of 3G • 3GPP R99 frozen in March 2000 • 3GPP R4 frozen in March 2001 • 3GPP R5 frozen in March 2002 or June 2002 • 3GPP R6 target time June 2003, estimated time December 2003 – UMTS is already a reality 6

    • Evo t f lu ion rom GSM to UMTS (2/12) • GSM offers 9.6 kb/s symmetric data connection • To provide service, VAS platforms as service nodes and centers were added to the GSM (e.g. SMSC, VMS) • Basic GSM and VAS are intended for mass people, to provide more individual services, IN were integrated with GSM (e.g. pre-paid, free- phone, etc.) • The capability limits support for data services • HSCSD was introduced – Bit rate increased from 9.6 kb/s to 14.4 kb/s for channel coding – 8 channels can be used, theoretical max bit rate is 115.2 kb/s, in reality bit rate is 40-50kb/s 8

    • Evo t f lu ion rom GSM to UMTS (GPRS) (4/12) • More data services were introduced, CS is not the best possible media for data traffic • GPRS was introduced and brought PS services into GSM • HW & SW changes in MS and BSS • New network elements, SGSN, GGSN, etc. introduced • Theoretical max speed is 171.2 kb/s using all 8 tiemslots • In reality 1 – 4 timeslots are used due to HW limitations • QoS can not be guaranteed due to – GPRS traffic is secondary traffic – GPRS traffic uses unused network resources, which can not be known exactly in advance 10
    • Evo t f lu ion rom GSM to UMTS (ED G E) (5/12) NMS Um A MS E-RAN NSS ISDN BTS BSC TRAU MSC/VLR GMSC PSTN PSPDN X.25 C HLR/AuC/EIR V I A HW&SW Changes A N M for EDGE S E Gb L Other Data Netwrok E-GPRS Packet Core SGSN GGSN Interent Introduction EDGE to GPRS system 11
    • Evo t f lu ion rom GSM to UMTS(ED G E) (6/12) • EDGE uses 8-PSK modulation enhancing thtoughput for both GPRS and HSCSD • Phase 1: – E-GPRS: data rate for PS traffic increased to 384 kb/s – BSS changed as E-RAN • Phase 2: – E-HSCSD: same speed for CS traffic (384 kb/s) • EDGE can deliver 3G mobile multimedia services using existing frequencies, bandwidth and carrier structure 12

    • Evo t f lu ion rom GSM to UMTS U MTS (3G PP R99) (8/12) • 3G introduces new radio access network UTRAN • UTRAN uses WCDMA as radio access technology • WCDMA is a global system for 3G mobile communicaitons • Interoperability of GSM/UMTS – E-RAN is modified to broadcast system information of WCDMA – Interworking functionality is introduced into 2G MSC/VLR for handling WCDMA 14
    • Evo t f lu ion rom GSM to UMTS U MTS (Features af r R99) (9 te /12) • Separation of connection, its control and services • Conversion to full IP 3G networks • Provision of enhanced multimedia services • Implementation of VHE • GERAN enhancemant • USAT enhancement • IMS implementation • End-to-end QoS • Enhancement of existing services and introduciton of new services 15

    • Su m m ary (1 2) / • Specifications Side – 3GPP R99, R4, and R5 have been frozen. R6 is estimated to be finalized in December 2003. – 3G/UMTS reveals a splendid world to all kinds of consumers, it intends to make everything available on moving, no matter when, where, who and what. • Vendors Side – Many vendors and operators have involved in 3G ventures. Most of them have already launched their 3G/UMTS products and push them to real operation or put them under trial. – It is estimated that only the key 3G vendors have been developing corresponding to R4/R5 products or have already had R4/R5 products partly. 43
    • Su m m ary (2 2) / • Users Side – 3G/UMTS terminals are no longer just simple phones. Users have to update their minds with new concepts for fully utilizing the functionalities of their new UMTS terminals and avoiding waste money and resources. • Markets Side – The most prospective potential markets for 3G/UMTS are still Asia Pacific Area, USA and Europe. – Compared to PSDN and GSM, 3G/UMTS systems are luxury systems for most of the ordinary users, especially at the beginning. • Final Words – To reach ”All IP”, the vendors have to overcome all the critical technical problems such as delay and other QoS related issues, the operators have to expand the coverage of 3G/UMTS systems with great financial support, and the users have to refresh their mind for using it. 44
