摘　　要：为实现WiMax网关间快速且平滑的切换,采用移动IP技术来实现其网关的切换。通过对WiMax网关切换、移动IP技术及GRE隧道封装机制的研究,来分析移动IP方式网关切换技术的实用性和可行性。为方便网络运营商的计费,使用双向隧道为移动IP的隧道机制。研究和仿真实验表明移动IP方式的WiMax网关切换技术在现实中是实用可行的。移动IP技术在WiMax网关切换中的应用能很好地实现WiMax网络中不同接入网关间的切换,有效降低切换时延和丢包率,且双向隧道也利于网络计费的实现。The application of mobile IP technology in the network of WiMax can make the switchover between different AGW quickly and smoothly.Analyze the feasibility of mobile IP mode switchover by the research of switchover of WiMax AGW,mobile IP technology and GRE tunnel encapsulation mechanism.For the convenience of charge,use bidirectional tunnul as the tunnel mechanism of mobile IP.Research and experimental results show that mobile IP mode switchover in WiMax AGW is practical and feasible in reality.The application of mobile IP technology can well realize the switchover between different AGW in the network of WiMax,which effectively reduces handoff delay and packet drop rate.And the mechanism of bidirectional tunnul is convenient for charge.
