摘　　要：针对网络移动性(NEMO)基本支持方案(NBS)中NEMO网络切换时延过长的问题,提出一种NEMO网络在代理移动IPv6(PMIPv6)中的实现方案,并针对其切换流程进行了进一步优化。新方案通过缩减经无线链路传输的切换信令条数以及提前建立数据转发隧道,实现了移动网络的快速切换。分析结果显示,新方案的标准切换流程和快速切换流程比NBS方案的切换流程分别减少了56.55%和58.63%的切换时延。To solve the long handover latency of mobile network in NEtwork MObility （NEMO） Basic Support （NBS）, this paper proposed a scheme for NEMO within PMIPv6. Then an improved handover procedure for this scheme was suggested. The proposed scheme, which decreased the number of handover messages transmitted on wireless link and in advance set up the tunnel to forward packets, achieved fast handover of mobile network. Compared with NBS＇ s handover procedure, the analytical results show that the standard handover procedure and fast handover procedure of the proposed scheme decrease handover latency by 56.55% and 58.63% respectively.
