Question: Under what condition should the Synchronised Radio Link Reconfiguration Preparation procedure **NOT** be initiated for a Node B Communication Context?
Option 1: When the existing Radio Link configuration is performing optimally.
Option 2: If there are no ongoing calls on the Node B.
Option 3: If a Prepared Reconfiguration already exists for the context.
Option 4: When the Node B is undergoing a software update.
Explanation: Initiating a new preparation while one is already pending (Prepared Reconfiguration) could lead to conflicts or inconsistencies in Radio Link configuration, potentially disrupting service quality. Thus, protocol dictates waiting for the resolution of the existing prepared state before proceeding with new configurations.
