    • Influence on a key used between a user equipment and a base station, which will be imposed by unsecured updating of a key between the base station and a relay node when a relay node is being introduced is diminished. An HO request processing unit (202) extracts user equipment information from an HO request input from a receiver (201). A user equipment information determination section (204) determines a mode of handover from the user equipment information, and outputs a determination result to a key generator (205) and an HO command generator (207). In relation to a determination about a mode of handover on the basis of user equipment information, it is determined whether the handover is handover from a relay node to a base station, handover from a base station to a relay node, handover relating to relay nodes subordinate to the same base station, and the like. Then, preparation of handover command, updating of a key, and the like are performed in conformance with the mode of handover
    • 当中继节点被引入时,对基站和中继节点之间的密钥的不安全更新所施加的对用户设备和基站之间使用的密钥的影响减小。 HO请求处理单元(202)从从接收器(201)输入的HO请求中提取用户设备信息。 用户设备信息确定部(204)从用户设备信息确定切换模式,并将确定结果输出到密钥发生器(205)和HO命令生成器(207)。 关于基于用户设备信息的切换模式的确定,确定切换是从中继节点到基站的切换,从基站到中继节点的切换,与中继节点的切换 从属于同一基站等。 然后,根据切换模式来执行切换命令的准备,密钥的更新等

    • A wireless communication base station (10) comprises a system information generating unit (20) that generates system information including a several system information messages, a paging message generating unit (22) that generates a paging message including a modification flag that indicates whether or not the system information has been modified; and a transmitter (18) that transmits the system information and the paging message. The system information generating unit (20) generates system information including a system information message in which an emergency message is described, and the paging message generating unit (22) generates a paging message that further includes information indicating that the emergency message is present in the system information and an identifier that identifies a system information message in which the emergency message is described. Consequently, a wireless communication base station can be provided which is capable of urgently notifying system information to be broadcast at a schedule according to the urgency of the system information while suppressing modifications to the system information as much as possible.
    • 无线通信基站(10)包括生成包括多个系统信息消息的系统信息的系统信息生成单元(20),生成包含指示是否进行修改的标志的寻呼消息的寻呼消息生成单元(22) 系统信息已经修改; 以及发送系统信息和寻呼消息的发送器(18)。 系统信息生成部(20)生成包含描述了紧急消息的系统信息消息的系统信息,并且寻呼消息生成部(22)生成寻呼消息,该寻呼消息还包括表示紧急消息中存在的信息 系统信息和识别描述了紧急消息的系统信息消息的标识符。 因此,可以提供一种无线通信基站,其能够根据系统信息的紧迫性紧急地通知按照时间表广播的系统信息,同时尽可能地抑制对系统信息的修改。
