摘　　要：结合链路层和网络层切换,在研究分析全球微波互联接入(worldwide interoperability for microwave access,WIMAX)网络的基础上,给出w-FHMIPv6(WIMAX-fast handover for hierarchical mobile IPv6)移动管理方案。在FH-MIPv6的机制上引入一种快速触发机制,使切换过程的丢包率和切换时延都可以得到改善;同时,该方案需要的链路层信号和信息交互也较少,利于快速切换的实现。通过网络仿真对FHMIPv6和w-FHMIPv6管理方案的网络性能进行比较分析,移动管理方案w-FHMIPv6能够降低通信链路中的丢包率和传输时延。With a combination of link layer and network layer handover, the paper proposed a WIMAX Fast handover for hierarchical mobile IPv6 （w-FHMIPv6） mobility management scheme based on access networks of WIMAX. One kind of fast trigger mechanism was introduced in the FHMIPv6 mechanism. Both of the packet loss rate and the handover latency can be improved by the mechanism; at the same time, this scheme needs alternately few on the link layer signal and the ex- change information, and favor the fast handover of the realization. The network performance of FHMIPv6 and w-FHMIPv6 management scheme was comparatively analyzed by the network simulation. The w-FHMIPv6 management scheme can lower the package loss rate and the transmission latency in the communication link.
