Title:	LS on Enhanced User Identity Confidentiality

S2 thanks S3 for their LS on ‘Enhanced User Identity Confidentiality’ (S2-99825; S3-99254), that clarifies the status of this 3G security feature. 

S2 has recognized that the use of the feature ‘Enhanced User Identity Confidentiality’ is HE-optional but that the transport mechanism between SN and HE has to be implemented by all UMTS SN to prevent problems in roaming conditions. 

From S2 point of view the work on this feature has to continue and encourages all other TSGs (esp. CN1, CN2, T3, IGC on security) to consider the implications occuring by the implementation of the 3G security features and to make sure that the appropriate extensions will be added to the relevant documents for release 99.
