基于网络的局域性移动性管理研究

Research on network-based mobility management protocol

目前的全局性移动性管理方案存在着许多缺点,不适合未来移动性对于低时延、低复杂度、易于管理的要求。为此本文分析了全局性移动性管理的局限性,针对移动终端局部的小范围的移动需求,提出了一种基于网络的局域性移动性管理解决方案F-PMIPv6,该方案将快速切换的方法应用到PMIPv6协议中,极大地缩短了切换时延,可以适用于时延敏感的业务。

There are many shortcomings in the existing global mobility management protocols. They are not suitable for the future mobility management, which requires low handoff latency, low-complexity and manageability. Therefore the paper analyses the limitation of global mobility management protocols, then proposes a network-based local mobility management solution, for the requirement of the mobile node moving in small local area. In our proposal, the fast handoff method would be used in the PMIPv6 protocol. So the proposal solution could largely shorten handoff latency and suit the latency-sensitive service.
