Question: Under what condition can the Dedicated Measurement Termination procedure be initiated by the CRNC if a Prepared Reconfiguration exists?
Option 1: If the measurement was related to cell load.
Option 2: If the measurement was specifically for signal strength.
Option 3: If the Node B is undergoing software upgrade.
Option 4: If the measurement was initiated using the reserved value 'All NBCC'.
Explanation: This condition highlights an exception to the general rule that Dedicated Measurement Termination cannot be initiated during a Prepared Reconfiguration. Initiating with 'All NBCC' is a special case, allowing for termination at any time, even under Prepared Reconfiguration, showcasing the importance of precise parameter usage in network management procedures.
