Question: In UTRAN Iub interface NBAP signalling, when an ERROR INDICATION message containing an error is received by a Node, what action should be taken regarding the Error Indication procedure?
Option 1: Trigger the Error Indication procedure in the receiving Node to notify the sender.
Option 2: Ignore the error and continue with ongoing procedures as if no error occurred.
Option 3: Initiate local error handling in the receiving Node without triggering the Error Indication procedure.
Option 4: Automatically terminate all active procedures in the receiving Node.
Explanation: When an ERROR INDICATION message with any type of error is detected, the receiving Node should prioritize local error handling over initiating the Error Indication procedure, managing errors internally first and potentially preventing unnecessary external notifications or procedure terminations.
