Question: What is the primary purpose of the Iur Deactivate Trace procedure in UTRAN's Radio Network Subsystem Application Part (RNSAP) signalling?
Option 1: To initiate a new Trace Session for a UE Context on the DRNC.
Option 2: To modify the configuration of an existing Trace Session for a specific UE.
Option 3: To inform the DRNC to stop a Trace Session for the concerned UE Context and indicated Trace Reference.
Option 4: To request the status of all active Trace Sessions from the DRNC.
Explanation: The Iur Deactivate Trace procedure is used to stop (deactivate) a Trace Session for a specific UE Context and Trace Reference on the DRNC, efficiently managing trace operations within the UTRAN network.
