Question: In UTRAN Iur interface RNSAP signalling, when an ERROR INDICATION message containing an error (e.g., Transfer Syntax Error) is received, how should the receiving Node proceed?
Option 1: Trigger the Error Indication procedure and notify the sending Node.
Option 2: Ignore the error if it's an Abstract Syntax Error with 'ignore and notify' criticality.
Option 3: Initiate local error handling without triggering the Error Indication procedure.
Option 4: Terminate all ongoing procedures with the sending Node.
Explanation: According to the specified error handling precedence, when any type of error is detected in an ERROR INDICATION message, the receiving Node should prioritize local error handling over initiating the Error Indication procedure, ensuring contained management of errors at the point of detection.
