Abstract: Based on problems in the high-speed railway mobile communication system,the prediction-based handoff method of mobile high-speed railway has been proposed.According to the table for train path,mobile nodes designate the next access routing in advance before switching,judgment for switching directions is accurate,and configuration of subnet prefix,care-of address can be accomplished ahead.The switching efficiency will increase and problems such as low utilization of network resources and switching delay can be resolved via NS2 simulation experiments.

摘要: 针对高速铁路的运行特点,提出一种基于预测的高速铁路移动通信切换方法,引入列车路径信息表,移动节点切换到新链路前预先指定下一接入路由,准确判断切换方向,提前完成配置子网前缀和新转交地址过程。通过NS2仿真实验证明,该方法提高了切换效率,解决了网络资源利用率低和切换延迟大的问题。
