Question: In UTRAN Iu interface RANAP signalling, what is the primary purpose of the Message Structure Information Element (IE) in error reporting scenarios?
Option 1: To provide a flat list of all possible error codes in the RANAP protocol.
Option 2: To offer a hierarchical view of message structure from top level down to the lowest relevant level for an occurred error.
Option 3: To assign priority to different types of errors based on their impact on network performance.
Option 4: To specify the version of the RANAP protocol in use when an error occurs.
Explanation: The Message Structure IE provides a structured, hierarchical view of the message from top level down to the lowest level relevant to the reported error, facilitating targeted troubleshooting and error resolution in UTRAN Iu interface RANAP signalling.
