Question: What is the primary purpose of the Common Measurement Value Information IE in UTRAN Iur interface RNSAP signalling?
Option 1: To exclusively indicate the absence of measurement values in a message.
Option 2: Solely to provide the actual Common Measurement Value without indicating its presence or absence.
Option 3: To inform whether the Common Measurement Value is included in the message and, if so, to provide the value itself.
Option 4: To manage the frequency of measurement reports between RNS entities.
Explanation: The correct answer aligns with the nuanced role of the Common Measurement Value Information IE. It serves a dual purpose: signaling whether the Common Measurement Value is present within the message, and if present, conveying the value itself, ensuring efficient handling of measurement data in UTRAN Iur interface RNSAP signalling.
