Question: In E-UTRAN, how are duplicated warning messages (received via S1-flex or from both EPC and 5GCN) identified to prevent transmission on the radio interface?
Option 1: By analyzing the message content for similarities
Option 2: Through periodic network scans for identical broadcasts
Option 3: By checking the message identifier and serial number fields
Option 4: Using a timer-based mechanism to filter out duplicates
Explanation: In E-UTRAN, to efficiently manage and prevent the transmission of duplicated warning messages on the radio interface, the network relies on specific identifiers within each message. The message identifier and serial number fields serve as unique markers, enabling the eNodeB to detect duplicates accurately, ensuring only unique warning messages are transmitted, optimizing radio resource utilization and minimizing unnecessary alerts to User Equipment (UE).
