MTM’99 Workshop


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

MTM’99 Workshop


Virtual Home Environment VHE

• 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

MTM’99 Workshop


3rd generation considerations

• 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

MTM’99 Workshop


Current status of UMTS

• 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

MTM’99 Workshop


UMTS phase 1 roll-out

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

MTM’99 Workshop


UMTS phase 1 roll-out

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

MTM’99 Workshop


P848 Deliverable 1 recommendations

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.

MTM’99 Workshop


P848 Deliverable 1 recommendations

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'.

UMTS and IP - where are Telcom Operators?

• 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

MTM’99 Workshop


Three proposals retained for 1999 work programme

P919 Evolution of Integrated Fixed and Mobile Networks Evolution of architecture, scenarios for interim steps

P920 UMTS Network Aspects Network aspects in UMTS, concentrating on protocols. Vision: same type of VHE and mobility management protocols

P921 UMTS Radio Access Analyse 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

MTM’99 Workshop


P919 Evolution of Integrated Fixed and Mobile Networks

• 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

MTM’99 Workshop


P920 UMTS Network Aspects

• 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

MTM’99 Workshop


P921 UMTS Radio Access

• 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
