Question: What is the primary purpose of the Synchronized Radio Link Reconfiguration Cancellation procedure in UTRAN's Iub interface Node B Application Part (NBAP) signalling?
Option 1: To initiate a new configuration for Radio Links within the Node B.
Option 2: To modify existing communication control ports for Node B Communication Contexts.
Option 3: To activate previously prepared Radio Link configurations in the Node B.
Option 4: To release (cancel) a previously prepared new configuration for Radio Link(s) within the Node B.
Explanation: The correct answer is Option 4 because the Synchronized Radio Link Reconfiguration Cancellation procedure is specifically designed to instruct the Node B to abandon or release new Radio Link configurations that were set up by a preceding preparation procedure, ensuring resources are freed up and the Node B returns to its previous state regarding those specific links. This action is crucial for efficient resource management and maintaining the integrity of the network's configuration.
