Question: What is the primary purpose of including a Test Flag Information Element (IE) in a Cell Broadcast Service (CBS) request to an NG-RAN node?
Option 1: To prioritize the broadcast message over regular traffic, allocating additional resources if necessary.
Option 2: To indicate that the message should be broadcast immediately, bypassing any scheduling delays.
Option 3: To signal that the request should be processed normally but without actual over-the-air broadcast or resource allocation.
Option 4: To notify the NG-RAN node to cancel all pending CBS requests before processing this one.
Explanation: The Test Flag IE allows for testing of the CBS request processing pipeline without actual dissemination of the message over the air or commitment of network resources, crucial for development, troubleshooting, and quality assurance in telecom networks.
