Question: Under what condition should the Compressed Mode Command procedure NOT be initiated for a Node B Communication Context?
Option 1: When the Node B is already in compressed mode.
Option 2: When a Prepared Reconfiguration exists.
Option 3: During handover procedures to ensure seamless connectivity.
Option 4: If the User Equipment (UE) does not support compressed mode.
Explanation: The correct answer is Option 2 because, according to the specifications, initiating a Compressed Mode Command procedure is prohibited if a Prepared Reconfiguration exists. This ensures that configuration changes are managed in an orderly fashion, preventing potential conflicts or inconsistencies in the Node B's operational state. This highlights the importance of coordinated configuration management in UTRAN (UMTS Terrestrial Radio Access Network) to maintain network stability and performance.
