Question: What does the "Number of Broadcasts Completed List" Information Element (IE) primarily indicate when sent from the Radio Network Controller (RNC) to the Core Network (CN)?
Option 1: The signal strength of each Service Area for broadcast optimization.
Option 2: The number of User Equipment (UE) reached in each Service Area during a broadcast.
Option 3: The number of times a CN message has been sent to each Service Area over the radio interface.
Option 4: The list of Service Areas where broadcasting is currently not possible due to network issues.
Explanation: This option correctly reflects the information conveyed by the "Number of Broadcasts Completed List" IE, which is about tracking the broadcast frequency of CN messages across different Service Areas via the radio interface. This is crucial for managing and monitoring broadcast services efficiently in a UTRAN (Universal Terrestrial Radio Access Network) environment.
