name: URI
full_form: Uniform Resource Identifier
context: It is assumed that SIP URI or TEL URI wonât be changed for bypassing LI purpose because the SIP message otherwise wonât be routed correctly. If the SIP URI matches the target identify, LI can use two methods to know which KMS it should go to in order to retrieve the master media key. The first method is that the user terminal always uses its home KMS and the URI of the user binds with the URI of the KMS by a natural way, such as if the SIP URI is username@abc.com, then its KMS URI is: kms@abc.com. The second method is more dynamic; that either terminal transfers its current KMS identity to the core network, or core network allocate a KMS for a user and then send the KMS identity to the user. This method is more flexible in that one user can use multiple KMSs. In this solution, the LI function can grab the user identity from signalling. All necessary key material or credentials for LI comes from KMS rather than signalling because the LI may otherwise grab the corrupted key material or
description: A Uniform Resource Identifier (URI) is a parameter used to identify and locate resources on the internet. In telecommunications, it's specifically used to identify SIP messages and user identities within the context of lawful intercept.
explanation: The description explicitly states that URI is a parameter used for identification in telecommunications, particularly for SIP messages and user identities related to lawful intercept. This aligns with the definition of a parameter as a value associated with a specific entity or function.
