Using auxiliary information to direct users of wireless devices to safety in response to emergency alert system alerts
摘要：
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.

方法和无线设备（120,122）利用与紧急警报系统警报消息相关联的辅助信息来引导无线设备（120,122）的用户的安全。 无线通信系统（102）向无线设备（120,122）无线地发送紧急警报系统（EAS）警报消息。 无线通信系统（102）还向无线设备（120,122）无线地发送增强的EAS警报消息。 增强的EAS警报消息包括向无线设备（120,122）提供信息以引导无线设备（120,122）的用户移动朝向安全区域（150）中的至少一个并且远离 危险区（158）。 增强EAS警报消息中的辅助信息可选地基于无线设备的位置，安全区域和危险区域以及受危险区域影响的附近的后勤的任何组合进行调整。
