Full Description

Version 1.0.0 of this TR will be circulated to other ETSI TBs and outside ETSI for comment. ________ Standardisation work beyond the Initial Phase of UMTS (the initial phase of UMTS is covered by the Third Generation Partnership Project - 3GPP) will initially focus on Services and Systems Architecture. Examples of work to be studied in this report include the vision for UMTS based on IP, ATM, IP over ATM, etc...; Virtual Home Environment (VHE), Virtual Network Operators (VNO)... using as a basis U-99031. What should be the role of EP UMTS in defining the key characteristics for UMTS Phases 2 / 3? Should any of the above tasks be done elsewhere in ETSI or should they all be performed / managed within EP UMTS? - ------------ 1.What do we mean by a Broader approach to UMTS? 2.What are the benefits for ETSI of complementing the GSM based approach to UMTS being adopted in 3GPP by the development of alternative and longer term approaches ? 3.What are the market drivers for alternative approaches to UMTS? 4.What is needed for UMTS that will not be provided in the Initial phase of UMTS being developed in 3GPP? - (a) Radio and Transmission Aspects. - (b) Network and Terminal Aspects. 5.What impact does the recent Trans Atlantic Business Dialogue (TABD) have on ETSI's work for UMTS? - How should EP UMTS relate to the Operators Harmonization Group (OHG)? 6.How is ETSI going to respond to 3GPP2 and other members proposed for the IMT-2000 family in the ITU? - (a) ITU Aspects. - (b) 3GPP / 3GPP2 Aspects. 7.When will alternate technologies to the transport of voice and data over ATM (AAL2/AAL5) be available for UMTS ? - What will these technologies be? 8.What are the key characteristics for UMTS Phases 2/3 that will not be provided in the Initial Phase of UMTS in 3GPP? _______________ Supporting organisations (BT, Alcatel, France Telecom, DTI, Nortel, Motorola, ...)
