Question: In a Cell Broadcast Service (CBS) scenario, when a CBCF sends a WRITE-REPLACE-WARNING-REQUEST-NG-RAN to the AMF for an ETWS Primary Notification, how does the NG-RAN node handle the included Repetition Period IE and Number of Broadcasts Requested IE?
Option 1: The NG-RAN node processes these IEs as per standard CBS procedures.
Option 2: The NG-RAN node partially processes these IEs, considering only the Repetition Period.
Option 3: The inclusion of these IEs triggers an error response from the NG-RAN node.
Option 4: The NG-RAN node ignores both the Repetition Period IE and the Number of Broadcasts Requested IE.
Explanation: For ETWS Primary Notifications, specific rules apply to ensure swift and efficient dissemination of critical alerts. Ignoring the Repetition Period IE and the Number of Broadcasts Requested IE by the NG-RAN node when included in a WRITE-REPLACE-WARNING-REQUEST-NG-RAN for an ETWS Primary Notification is a design choice that likely prioritizes immediate alert delivery over customizable broadcast repetition, ensuring timely warning dissemination to users.
