Question: What happens when a Node receives an ERROR INDICATION message containing any type of error (Transfer Syntax, Abstract Syntax, or Logical Error) on the UTRAN Iu-BC interface?
Option 1: The receiving Node triggers the Error Indication procedure and notifies the sending Node.
Option 2: The receiving Node initiates local error handling but does not trigger the Error Indication procedure.
Option 3: The receiving Node ignores the ERROR INDICATION message due to potential Abstract Syntax Errors with "ignore and notify" criticality.
Option 4: The procedure is considered successfully terminated, and no further action is taken.
Explanation: In scenarios where error handling for ERROR INDICATION messages is concerned on the UTRAN Iu-BC interface, the receiving Node's protocol dictates triggering the Error Indication procedure to ensure proactive issue resolution and notification to the sending Node, reflecting a collaborative error management approach.
