摘　　要：移动IPv6协议解决了移动IPv4协议三角路由问题,实现路由的优化;层次移动IPv6协议(HMIPv6)可以减少标准切换引起的连接中断时间,维持或提高已有连接的通信服务质量,是移动IPv6的重要扩展.但是HMIPv6依然存在问题,HMIPv6对移动节点区域间的切换注册开销和时延性能上没有任何改进,甚至比标准IPv6的注册过程更多一次新的域内注册过程;对移动迅速的移动节点带来沉重的注册开销负担.对此提出一种新的HMIPv6切换改进策略,客观上可减少网络中注册、绑定和更新消息,减轻网络的负担.Mobile IPv6 protocol solves the triangulation problem of mobile IPv4 protocol and realizes the optimization of routing. Hierarchical mobile IPv6 protocol (HMIPv6) can reduce the connection interruption time caused by standard switching, maintain improve the communication service quality of existing connections, and is an important extension of mobile IPv6 protocol. But, HMIPv6 has no improvement on the handover of inter-domain cost and delay performance of mobile nodes, even more time needed than the standard IPv6 registration process. It brings heavy burden of registration cost to mobile nodes which move quickly. In this paper, a new HMIPv6 handover improvement strategy is proposed for the existing problems of HMIPv6. Objectively, it can reduce the registration, binding and update messages in the network and reduce the burden of the network.
