Question: Under what condition is the UE Measurement Termination procedure **not** initiated by the DRNC in a UTRAN environment?
Option 1: When the UE is in idle mode.
Option 2: If the measurement was not previously requested by the UE Measurement Initiation procedure.
Option 3: If a Prepared Reconfiguration exists for the relevant UE Context.
Option 4: When the signalling bearer connection for the UE Context is unavailable.
Explanation: The DRNC withholds initiation of the UE Measurement Termination procedure if a Prepared Reconfiguration (an impending change in the UE's configuration) exists, to prevent potential conflicts or inconsistencies, ensuring smoother management of UE configurations and measurements.
