Document for:	Discussion/Decision

1.	Introduction
In the last TSG-T meeting held in Florida, we approved that TSG-S1 should define the service requirements and other WGs should be responsible for the development of technical capabilities.
This document proposes its procedure to help TSG-S1 and other WGs to recognise their responsibilities and targets. 
First of all SWG6 should define the categories for terminal types. They would be used as a basis for the discussion of terminal capabilities in other relevant WGs.

2.	Principle for the terminal capabilities and terminal types
Terminal Capabilities are consists of “implementation capabilities” and “service capabilities”. Implementation capabilities can be used to register and exit in their network, so they are independent of services. Service capabilities can be used to realise each service or combination of services.
Implementation and service capabilities should be defined for the each technical domain and each service respectively.

3.	Framework for the terminal categories
Terminal could be categorised into several classes from the radio interfaces and services perspective.
The following table shows the examples for axes of categories. More axes should be considered and more combinations could be defined by SWG6. But some typical examples should be indicated to TSG-S1 and other relevant WGs in accordance with our concerns.
Furtheremore we should give priorities for some categories to ensure that we will start IMT-2000 service in 2001.

			Category 1
(non-service terminal)	Category 2
(speech only terminal)	
Non-services	Single-mode/Dual-mode (2G/3G)	Single-mode	Single-mode	
	FDD / TDD	FDD	FDD	
	fixed duplex / variable duplex	fixed duplex	fixed duplex	
	interfrequency intracell handover / interfrequency intercell handover	interfrequency intracell handover	interfrequency intracell handover

		Short Message Services	-	-	
	Supplementary Service		-	-	
	Bearer Services	Circuit switched data	-	-	
		Circuit switched fax	-	-	
		Packet switched data	-	-	

4.	Conclusion
We propose that the terminal categories should be identified and prioritised from the terminal perspective by TSG-T2 SWG6. TSG-S1 should confirm if our thought would fit to their service requirements. Other WGs should identify technical capabilities along to service requirements from TSG-S1 and terminal categories from TSG-T2 SWG6. But finally terminal categories should be merged with terminal capabilities or its combinations.
