    • A control device being a control device communicating with a controlled device to control the controlled device includes: a first memory to store first authentication information for authenticating the controlled device; a second memory to store second authentication information for making the controlled device authenticate itself; a determination unit to compare third authentication information sent from the controlled device for specifying the controlled device with the first authentication information; a calculator to perform calculation processing on the first authentication information or the third authentication information using the second authentication information to generate a calculated value; a transmitter to transmit, when the determination unit determines that the first authentication information and the third authentication information are the same, the calculated value to the controlled device; and a memory controller to update the first authentication information.
    • 作为控制装置的控制装置,与控制装置通信以控制受控装置,包括:第一存储器,用于存储用于认证受控装置的第一认证信息; 第二存储器,用于存储用于使受控设备自身认证的第二认证信息; 确定单元,用于将从受控设备发送的用于指定受控设备的第三认证信息与第一认证信息进行比较; 使用所述第二认证信息对所述第一认证信息或所述第三认证信息进行计算处理的计算器,以生成计算值; 当所述确定单元确定所述第一认证信息和所述第三认证信息相同时,发送器将所计算的值发送到所述受控设备; 以及存储器控制器来更新第一认证信息。

    • An information communication scheme for enabling the radio base station to carry out both point-to-point user information communications and point-to-multipoint user information communications with respect to radio terminals is disclosed. A first media access control identifier is allocated to a radio terminal which made a connection request, a correspondence between the first media access identifier and the radio terminal is broadcast, and a user information destined to the radio terminal is transmitted using a time-slot corresponding to the first media access control identifier. On the other hand, a second media access control identifier is allocated to a multicast information identifier, a correspondence between the second media access control identifier and the multicast information identifier is transmitted, and the multicast information is transmitted using a time-slot corresonding to the second media access control identifier.
    • 公开了一种用于使无线基站能够对无线终端进行点对点用户信息通信和点对多点用户信息通信的信息通信方式。 第一媒体访问控制标识符被分配给作出连接请求的无线终端,广播第一媒体访问标识符和无线终端之间的对应关系,并且使用对应于时隙的时隙来发送去往无线终端的用户信息 到第一媒体访问控制标识符。 另一方面,向多播信息标识符分配第二媒体访问控制标识符,发送第二媒体访问控制标识符和多播信息标识符之间的对应关系,并且使用与该多播信息标识符相对应的时隙来发送多播信息 第二媒体访问控制标识符。
