Question: In UTRAN Iu interface RANAP signalling, when a logical error occurs in a Class 1 request message without a specific outcome report message, what action is taken?
Option 1: The procedure continues with default values.
Option 2: The procedure is terminated and the Error Indication procedure is initiated with an appropriate cause value (e.g., Semantic Error).
Option 3: The receiver sends a request for retransmission of the erroneous message.
Option 4: The logical error is ignored, and the next message in the sequence is processed.
Explanation: According to specified behavior for Class 1 procedures in UTRAN Iu interface RANAP signalling, if a logical error occurs in a request message without a specific outcome report message, the procedure is terminated. An Error Indication procedure is then initiated with an appropriate cause value (e.g., Semantic Error) for transparency and corrective actions.
