The invention relates to a method for solving proxy mobile IPv6 group switching based on link layer grouping. Specifically, the present invention is to solve the problem in the proxy mobile IPv6 domain, when a group of MN from the same P-MAG switch to another N-MAG, this MN can be registered in the form of group; and when the MN from N-MAG left, also can be in the form of group to unbind and leave. The purpose of the invention is realized by expanding the function of MAG, which is based on the link layer of the MN packet, and maintain packet information until MN left; extend the functionality of LMA, so that it can record and maintain the grouping information; extended PBU defined in RFC5213, PBA and DeReg PBU message format, make? It can support the MN switch to the form of a group. The method of the invention can effectively reduce the switching delay and signaling overhead when the MN moves in group form, and is favorable for promoting the application of PMIPv6 in the delay sensitive service.

1.一种基于链路层分组的代理移动IPv6组切换解决方法,其特征在于:A、当移动节点(MN)从前一个接入网关(P-MAG)切换到下一个接入网关(N-MAG)时,N-MAG基于链路层对切入N-MAG的MN进行分组;B、将RFC5213中定义的PBU、PBA和DeReg PBU消息扩展为gPBU、gPBA和DeReggPBU消息,以支持MN以组的形式进行切换;C、N-MAG对切入的MN进行分组并记录分组信息后,同一组的MN可以以组的形式进行注册;D、同一组的MN可以以组的形式离开N-MAG,也可以以非组的形式离开N-MAG。
