  1. The Status of UMTS Josef Noll, Telenor AS Josef.Noll@fou.telenor.no

  2. EURESCOM P848 project team:British Telecom, CSELT, France Telecom, Swisscom, Finnet Group, and Telenor Strategic study performed in IV.1998 Deliverable 1:The status of UMTS Deliverable 2:EURESCOM strategic wish list for UMTS presented by: Josef.Noll@fou.telenor.no The Status of UMTS

  3. The overview of UMTS today: Standardising groups, definitions of UMTS, FMC included, influence & conflicts, impact of “phased approach” Operators wish list for UMTS (next presentation by Geoff Richman, BT):Essential, additional features UMTS related work in EURESCOM in 1999:Achievements, implications, adoption of results Strategic Study P848

  4. The operators view of UMTS in 1998 1 Active groups in the UMTS domain 2 Comparing the definitions of UMTS 3 Evaluation of the phased approach and IMT-200 family concept 4 Assessment of current status of UMTS 5 Implications of the UMTS evolution scenarios for the Telcos 6 Recommendations for assisting the emergence of UMTS P848 Deliverable 1

  5. Active Groups in UMTS

  6. Terminology in used UMTS

  7. Phase approach • UMTS forum: 2 Mbit/s service in phase 1, phase 2 with extension to 155 Mbit/s (WLAN, Hiperlan) and S-UMTS services • ITU: function requirements for phase 1, nothing yet for phase 2 • GSM MoU: Definition of multimode terminals • FMC: a) Fixed and Mobile service integration (2 sets), b) common services, c) network integration, d) same equipment

  8. Virtual Home Environment (VHE) = personalised service portability across network boundaries and between terminals Depends on terminal capability, USIM (UMTS SIM) VHE is a combination of capabilities located in the service provider, network operators and terminal equipment = distributed user profile. Profile outline will be owned by the service provider; at any instant it may be distributed between the Terminal Equipment, USIM, Network Operator and Service Provider. Conclusion: Important for operators to become service providers Virtual Home Environment VHE

  9. ETSI’s GMM has clear vision of 3rd generation:Three ways to 3rd generation: Fixed, mobile and IP (or others). MoU and UMTS forum see an evolution from GSM:- too much concentration on interworking? Different approach in standardisation from ETSI and IETF:- single members versus organisations- drafts to experience versus approved technology 3rd generation considerations

  10. GPRS roll-out is not secured. First ideas presented by manufacturers, but far from being complete. No GPRS demonstrator available:- impact on air interface not clear (capacity)- service development for GPRS not (?) existing Late GPRS might hamper UMTS in Europe Standardisation: New SMG organisation, intern. 3GPP Standardisation after phase 1 not clear, future network:voice over IP, real-time voice, QoS control, pricing, IPv6 Current status of UMTS

  11. Standardised regulatory issues, common European approach, including National roaming for ‘inexpensive’ service provision UMTS shall be seen an extension of the existing network, full coverage might be provided in later years (refarming of the access network). Allow 3g functionality in 2g systems using VHE environment. Allow operators to start with a substantial UMTS band, e.g. 2 x 15 + 5 MHz UMTS phase 1 roll-out

  12. International aspects Tighter schedule in Japan, NTT DoCoMo UMTS (phase 0) in 2001. -> Japan gains experience and sets standards Need for ’cheap' UMTS demonstrator and simulation tools, in Europe Co-operation with Universities, Research Labs and TelCos is required to get an early UMTS UMTS phase 1 roll-out

  13. Traffic analysis: home/office versus public networks. Success to penetrate the market. Identification of 'killer applications'. Develop 'cheap' UTRA demonstrator to enhance knowledge of Universities, industry and TelCos. Network planning. TDD and FDD simulations, alternative network design. National roaming, UMTS as a hot spot server. P848 Deliverable 1 recommendations

  14. Unique core network (IP based?) with various access networks, e.g. DECT, W-LAN, UTRA. IN evolution and FMC seems to go in parallel to UMTS Support service development based on IP (development potential and size of market). Analyse role of competitors from ‘non-Telecom’ areas (broadcast, IP) Standardisation activities with both 'Telecom' and 'IP'. P848 Deliverable 1 recommendations

  15. Mobile radio links: GSM, GPRS UTRA DECT WLAN, Cellular IP Fixed radio links: WLL LMDS DVB DAB The future access network From: http://www.fou.telenor.no/fou/umts

  16. Example - IP telephony

  17. UMTS/GPRS puts mobile operators in the IP business “Always on” has a big impact on IP networks and us as users Get ready for IP mania If you are not scared you don’t understand UMTS and IP - where are Telcom Operators?

  18. P919 Evolution of Integrated Fixed and Mobile NetworksEvolution of architecture, scenarios for interim steps P920 UMTS Network AspectsNetwork aspects in UMTS, concentrating on protocols. Vision: same type of VHE and mobility management protocols P921 UMTS Radio AccessAnalyse consequences of radio interface for different service types. Understanding and architecture aspects of 'software radio' and 'hybrid fibre radio’. All studies approx. 100 mm within one year, starting in 1999 Three proposals retained for 1999 work programme

  19. Mobile services by GPRS, EDGE, HSCSD, BRAN, TIPHON and UMTS. EURESCOM P809 is studying FMC across Telecom and IT networks Outcome: A study of services, potential architectures and topologies for integrated networks representing potential deployment options An evaluation of each architecture and topology from the operator perspective to identify the most attractive option(s) A description of the evolution path towards the preferred architecture(s) and topology(s) A consensus architecture(s) and topology(s) for promotion in standardisation fora A framework for network testing P919 Evolution of Integrated Fixed and Mobile Networks

  20. UMTS Phase 1 is GSM based using MAP and CAP, fixed network evolution using INAP. IETF has IP mobility and service control, ATM forum develops also mobility and service control It is apparent therefore that this UMTS Phase 1 will not include the true roaming VHE Outcome: Operator’s viewpoint of VHE Review of the global mobility and service control Proposal for capability and converged protocols across heterogeneous networks for delivery of VHE Final result will be a limited trial evaluation of VHE P920 UMTS Network Aspects

  21. Review of UMTS applications, transformation of ‘fixed’ applications to the wireless environment Requirements of QoS (Quality of Service) between applications and UMTS network, QoS parameters Outcome: Analysis of UMTS radio interface alternatives Development of a user plane emulator capable to simulate different radio interfaces (testing scenarios) Evaluation of applications performances in the UMTS environment Support of QoS requirements in a wireless environments P921 UMTS Radio Access
