Question: Which of the following best describes the purpose of the Common Measurement Termination procedure in UTRAN's Iur interface, as utilized by an RNC?
Option 1: To initiate new measurements for handover optimization across different RNCs.
Option 2: To modify existing measurement configurations for User Equipment (UE) in a cell.
Option 3: To establish a signalling bearer connection for a new Distant RNC Context.
Option 4: To terminate an ongoing measurement that was previously requested by the Common Measurement Initiation procedure.
Explanation: The correct answer accurately reflects the purpose of the Common Measurement Termination procedure. This procedure is specifically designed to end measurements started with the Common Measurement Initiation procedure, showcasing its role in managing ongoing measurement activities within UTRAN's Iur interface.
