Abstract
An alert broadcast system can receive a first alert message indicating an emergency from an alert management system. The first alert message generated by an emergency alert originator can include a unique identifier associated with the emergency. The alert broadcast system can forward the first alert message to a first group of wireless devices and cause each of the first group of wireless devices to temporarily store the unique identifier. The alert broadcast system can receive a second alert message, including the unique identifier from the alert management system. The alert broadcast system can forward the second alert message to a second group of wireless devices. The respective wireless device can perform an action based on a determination that the respective wireless device has received the first alert message prior to receiving the second alert message and that the second alert message is partly duplicative of the first alert message.
