Abstract: Based on the study and analysis of the existing IPv6 secure communication system for closed members，combining mobile nodes characteristic in the mobile IPv6 network，authors present a two-lays management system which is constructed by the predicted dwelling time of the mobile nodes.Through constructing a dynamic management node in mobile network，the author solves the expansion issues of the original solution in mobile IPv6 network environment properly.Finally，the author makes the simulation and analysis of this scheme.

摘要： 通过对现有的基于IPv6亲密伙伴的安全通信方案进行了研究和分析，结合移动IPv6网络中移动节点的特性，提出了一种基于移动节点预测驻留时间构造上层节点的双层管理机制。通过在移动网络中构造一个动态管理节点，妥善地解决了原方案在移动IPv6网络中的扩展问题。最后对新方案进行了仿真和分析。
