| 摘 要： | 无线网络不仅可以为用户提供更好的实时服务,而且可以提供更多的多媒体服务.本文提出了一种应用于GSM-R网络的小区切换的移动IPv6技术.该技术使用了分级的网络结构和移动代理点(MAP)优化路由方法,还可以为铁道系统设定路径指针.本文用M/M/1/k队列对小区内的高速列车通信特性进行建模,分析了其切换的延时和带宽利用率,并进行了仿真分析.结果表明此切换算法在列车高速运行时仍能够保持较好的性能.

| Abstract: | The wireless network provides subscribers not only more real time services but also more multimedia services. An effective cellular handoff technology based on the coming GSM-R network for railway combining with the mobile IPv6 technology is proposed scalable network architecture and mobile anchor point (MAP) optimized-route way, and also designs the route pointer especially for the railway. We models the communication process with M/M/1/k queue in the cell, then simulate and analysis the performance of handoff of high-speed train including the delay of handoff and the utility rate of bandwidth .The result indicates that train can keep the better performance even running in a high speed. |
