中文摘要：

目前的全局性移动性管理方案存在着许多缺点,不能适应未来移动性对于低时延、低复杂度、易于管理的要求。本文首先介绍了基于网络的局域性移动性管理协议PMIPv6,然后总结了基于PMIPv6的局域性域内移动性管理方案。最后针对目前关于PMIPv6域间切换管理的研究空白,首次提出了一种基于PMIPv6的域间切换移动性管理方案。针对最复杂的网络结构,并结合PMIPv6路由优化,设计了当MN在不同的LMA域间切换时的移动性管理方案,该方案不仅可以应用在本切换场景中,而且只需要简化步骤,即可用于其他的切换场景,所以具有很强的普遍性和适用性。

英文摘要：

The existing global mobility management protocols are not suitable for the future mobility management, which requires low handoff latency, low-complexity and manageability. First of all, the paper introduces a network-based local mobility management protocol, PMIPv6. Then the intra-mobility handover solution of PMIPv6 is specified. Focused on the research margin in in- ter-mobility handover management of PMIPv6, This paper is the first work to propose an intermobility handover management solution. The proposal adopts the method of PMIPv6 router optimization, and designs a handover management solution for the situation that MN moves between MAGs in different LMAs. The solution not only could be used in the most complicated handover scenario, but also could suit in the other simple scenarios by reducing the signalling steps. Therefore the solution will get good universality and applicability.
