| 摘 要： | 随着无线网络的快速发展以及各种无线接入网络的共存,为了满足用户的移动性需求,当用户移动时可以向用户提供不同网络的无缝垂直切换。从链路层到应用层比较实现切换技术的不同,进行传输层切换的改进方法,首先分析了拓扑场景以及切换过程,然后在切换转换过程中使用多路径并行传输技术以及切换过程中的平滑路径删除来保证切换的连续性。实践表明,该机制可以有效地保障切换的平滑性,对现有的切换有很好的指导意义。

| Abstract: | With the rapid development of wireless networks and the steady advancement of multiple wireless network's coexisting,in order to satisfy users' requirement of mobility,there is a rising demand of different seamless vertical handover mechanisms.From the analysis of the link layer to the application layer,the differences of these handover mechanisms are discussed,and then the transport layer handover mechanism is improved.First of all topology scenarios and handover process are analyzed,and then concurrent mu... |
