Abstract
A method and a wireless device (120, 122) utilize auxiliary information associated with an emergency alert system alert message to direct a user of the wireless device (120, 122) to safety. A wireless communication system (102) wirelessly transmits an emergency alert system (EAS) alert message to a wireless device (120, 122). The wireless communication system (102) also wirelessly transmits an augmented EAS alert message to the wireless device (120, 122). The augmented EAS alert message includes auxiliary information that provides information to the wireless device (120, 122) to direct a user of the wireless device (120, 122) to move at least one of toward a safe zone (150) and away from a danger zone (158). The auxiliary information in the augmented EAS alert message is optionally adjusted based on any combination of: the location of the wireless device, the safe zone, and the danger zone, and the logistics of a vicinity affected by the danger zone.
