Subject:	Reply to LS on additional Terminal Baseline Implementation Capabilities
	for secure interoperation with GSM

___________________________________________________________________________

T2/SWG6 would like to thank SA3 for LS T2-99921/S3-99329 on additional Terminal Baseline Implementation Capabilities for secure interoperation with GSM.

We added the table in the LS(T2-99921/S3-99329) to Annex A6 of TR21.904 with the slight modification from T2/SWG6 point of view. Based on the discussion in TSG-T#5 and TSG-SA#5, T2/SWG6 is now reconsidering the usage of the terminology “mandatory”. Hence, we substitute the terminology “mandatory” for the terminology “essential conditional” together with its condition.

The added text to TR21.904 is as follows :

Items	Essential/optional requirements for terminal baseline capabilities	related section
in TS33.102	
Interoperation between 3GPP and GSM systems	<Essential Conditional>
UEs that support GSM SIM or a GSM SIM application on the UICC shall include functions that allow conversion of security parameters from GSM to UMTS.	6.3.7.2
