Abstract: An IPv6(Internet Protocol version6) support method in a wireless communications system using an extension bridge is provided to control the transmission of a message a multicast address, transmitted to plural IPv6 nodes, as an IP destination address when terminals under an access router share common network prefix information, thereby reducing a waste of radio resources and the power consumption of the terminals. A bridge(200) comprises an ICT(Identification Cache Table) and an ND(Neighbor Discovery) relay agent. The ICT has the MAC(Media Access Code) of each terminal(311,321) connected to the bridge, an identifier for Point-to-Point connection between the bridge and the each terminal, and an IP(Internet Protocol) address and a valid flag value. The ND relay agent generates the ICT information of the terminal based on a neighbor solicitation message for DAD(Duplicate Address Detection) received from the terminal, and checks the duplicate of a random IP address of the terminal to determine the valid flag value. The bridge transmits data having a multicast address, transmitted to all nodes on the same link, as an IP destination address by referring to the ICT.
Abstract translation: 提供使用扩展桥的无线通信系统中的IPv6（因特网协议版本6）支持方法，用于控制传输到多个IPv6节点的多播地址作为IP目的地地址的消息传输，当接入路由器下的终端共享时 网络前缀信息，从而减少无线电资源的浪费和终端的功耗。 桥（200）包括ICT（识别缓存表）和ND（邻居发现）中继代理。 ICT具有连接到网桥的每个终端（311,321）的MAC（媒体接入码），桥与每个终端之间的点到点连接的标识符，以及IP（因特网协议）地址和有效标志 值。 ND中继代理基于从终端接收到的DAD（重复地址检测）的邻居请求消息生成终端的ICT信息，并检查终端的随机IP地址的副本以确定有效的标志值。 桥接器通过参考ICT将具有多播地址的数据发送到同一链路上的所有节点，作为IP目的地地址。
