Abstract: PURPOSE: A method for securing media independent handover message transportation is provided to protect MIH(Media Independent Handover) messages from an external attack by transmitting and receiving MIH messages through a secure channel. CONSTITUTION: A MMT(Multi-Mode Terminal,110) enables an authentication process of a second layer and an access router by an EAP(Extended Authentication Protocol). The access router transmits MAC(Medium Access Control) address of MSK(Master Session Key) and the terminal to an information server(120). The access router produces peer keys through MSK. The information server creates an information server key with the MSK. The peer key is used in security channel forming between the access router and the terminal. The information server key is used between the terminal and the information server for forming a secure channel.
Abstract translation: 目的：提供一种用于保护媒体独立切换消息传输的方法，以通过安全信道发送和接收MIH消息来保护MIH（媒体独立切换）消息免受外部攻击。 构成：MMT（多模式终端，110）通过EAP（扩展认证协议）实现第二层和接入路由器的认证过程。 接入路由器将MSK（主会话密钥）和终端的MAC（介质访问控制）地址发送到信息服务器（120）。 接入路由器通过MSK产生对等体密钥。 信息服务器使用MSK创建一个信息服务器密钥。 对等体密钥用于接入路由器和终端之间的安全通道形成。 在终端和信息服务器之间使用信息服务器密钥来形成安全信道。

Abstract: PURPOSE: A method and a system for allocating cell identification data are provided to improve identification performance between individual base stations in a communication system. CONSTITUTION: A management server initially allocates temporary cell identification data to a first base station(313). The first base station transmits the synchronization signal(315). The mobile terminal connected to the second base station grasps cell identification data of the synchronization signal(317). If the collision of cell identification data occurs, the second base station reports the collision of the cell identification data to a cell management server(321,323). The cell management server allocates the cell identification data to the first base station again(325).
