无线通信系统中配置公共警报系统密钥信息的方法和系统
摘要：
一种无线通信系统中配置公共警报系统密钥信息的方法和系统，该方法包括：CBC向无线通信系统中的网络实体发送用于密钥分发的消息，携带所述PWS密钥信息；所述无线通信系统中的网络实体接收到所述用于密钥分发的消息后，保存其中的PWS密钥信息。该公共警报系统(PWS)包括小区广播中心(CBC)和第一网络实体，其中：所述CBC用于向第一网络实体发送PWS密钥信息；所述第一网络实体用于保存所述PWS密钥信息。本发明提出了向UE分发PWS密钥信息的网络实体如何获得PWS密钥信息的具体方案，为UE从网络获得PWS密钥信息，实现PWS的安全保护奠定了基础。
摘要（英）：

The invention discloses a method and a system for configuring PWS (public warning system) key information in a wireless communication system. The method comprises the following steps that: a CBC (cell broadcast center) sends a message for key distribution to a network entity in the wireless communication system, wherein the message carries PWS key information; and after receiving the message for key distribution, the network entity in the wireless communication system stores the PWS key information in the message. The PWS comprises the CBC and a first network entity, wherein the CBC is used for sending the PWS key information to the first network entity; and the first network entity is used for storing the PWS key information. The invention provides a specific scheme of how to obtain PWS key information by the network entity distributing the PWS key information to UE (user equipment), thereby laying a foundation for obtaining the PWS key information from a network by virtue of the UE so as to realize the safety protection of the PWS.
