Question: What happens when a receiving SABP entity in UTRAN Iu-BC interface encounters an Abstract Syntax Error due to receiving IEs or IE groups in the wrong order or with too many occurrences?
Option 1: The receiver handles it based on Criticality information and Presence information for the affected IE/IE group.
Option 2: The receiver rejects the procedure and continues processing other messages.
Option 3: The receiver corrects the order or removes excess occurrences before proceeding with the message.
Option 4: The receiver sends a request for retransmission of the entire message set.
Explanation: According to the specified behavior, when IEs or IE groups are in the wrong order or have too many occurrences, the result is rejecting the procedure. This means the receiver does not attempt to correct or continue processing the flawed message but instead rejects it outright to maintain protocol integrity.
