摘　　要：针对层次化移动管理中的路径优化问题,提出了基于路径长度、流量资源、转发节点负载、承载协议、应用类型、用户偏好等因素的最优路径选择方法;使用最优路径选择方法,提出了基于移动IPv6的层次化移动管理框架;通过对建议框架地址管理的描述,阐述了最优路径选择的实现过程。针对层次化移动管理的部署和使用问题,描述了建议框架在自治系统中的使用方法;提出了软切换与硬切换相结合、层次化移动管理与非层次化移动管理相结合的集成状态转换模型,为终端系统提供了复杂网络环境下更好的移动性支持。To solve the path optimization problems in hierarchical mobility management, the optimum-path selection mechanism was proposed, based on ＂path length, transmission resources, forwarding-nodes＇ payload, carrying protocols, application types, users＇ preference, etc. ＂. With the selection mechanism, a hierarchical mobility management framework was proposed for Mobile IPv6. With the description of addresses management, the realization of optimumpath selection was explained in proposed framework. To solve the deployment and implementation problems of hierarchical mobility, the practice of proposed framework was described in Autonomous Systems. The integrated transition model of handovers was proposed, conjoined with soft and hard handovers, hierarchical and non-hierarchical mobility managements. With the proposed model, terminals can obtain better mobility supports in complex networks.
