摘　　要：在移动互联网络环境下,由于IPv4地址不足、移动支持能力不强、安全性差及移动通信需求量迅速增大等因素促使IPv6应运而生。在分析移动IPv6的特性、工作原理和移动互联网中直接应用移动IPv6存在问题的基础上,提出一种基于双向隧道通信模型的移动IPv6网络的改进设计方案,方案侧重于运用MPLS技术和重路由机制保证移动网的通信质量。通过构架实验环境进行对比模拟仿真,改进的移动IPv6网可以满足当前3G网络性能的需要,保证移动节点离开家乡代理进入外地路由器后节点之间可靠、有效的数据传送,改善了移动节点位置切换性能。In mobile Internet environment, the IPv6 is prompted to emerge because of the factors such as the insufficiency of IPv4 addresses, weak ability in mobile support, poor security and rapid expansion of mobile communication demand, etc. Based on analysing the characteristics of mobile IPv6, its working principle and the problems of directly applying the mobile IPv6 to mobile Interuet, we propose an improved design scheme of mobile IPv6 network which is based on bidirectional tunnel communication model. The scheme focuses in the use of MPLS technology and rerouting mechanism to guarantee the communication quality. Contrastive simulation is carried out through constructing the experimental environment, the improved mobile IPv6 network can meet the needs of current 3G network performance, ensures reliable and effective data transmission between nodes after the mobile node left home agent and entered into the router in other place, these improve the location switching performance of mobile node.
