    • Techniques for delivering and receiving emergency broadcast alert messages using Short Message Service (SMS) are described. In one design, a broadcast alert message for an emergency alert may be sent in an SMS broadcast message, e.g., by mapping at least one field of the broadcast alert message to corresponding field(s) of the SMS broadcast message and mapping remaining fields of the broadcast alert message to a data field of the SMS broadcast message. The SMS broadcast message may include a URI link for a website, broadcast reception information used to receive a broadcast channel, location information for an emergency event, etc. The SMS broadcast message may be carried in a system broadcast message sent to wireless devices. A wireless device may receive the system broadcast message, extract the SMS broadcast message, and obtain the broadcast alert message. The wireless device may detect for duplicate broadcast messages based on a hash digest generated for each broadcast message.
    • 描述了使用短消息服务(SMS)来发送和接收紧急广播警报消息的技术。 在一个设计中,可以在SMS广播消息中发送用于紧急警报的广播警报消息,例如,通过将广播警报消息的至少一个字段映射到SMS广播消息的对应字段并且映射剩余的字段 将广播提醒消息发送到SMS广播消息的数据字段。 SMS广播消息可以包括用于网站的URI链接,用于接收广播频道的广播接收信息,用于紧急事件的位置信息等。可以在发送到无线设备的系统广播消息中携带SMS广播消息。 无线设备可以接收系统广播消息,提取SMS广播消息,并获得广播提醒消息。 无线设备可以基于为每个广播消息生成的散列摘要来检测重复的广播消息。
