Abstract: Hierarchical Mobile IPv6(HMIPv6) is an improved technology based on Mobile IPv6(MIPv6). It is proposed to solve the handover problem during macro/micro mobility management. Aiming at that choose inconsequential Mobility Anchor Point(MAP) will increase service time-lag of the mobility node and the load of MAP is too convergent and so on, this paper proposes a LT-TMAP fast handover scheme on HMIPv6, and describes the carry out process in theory. Simulation results show that this scheme can use MAP resources of the network more effectively. It improves the handover efficiency and possesses better real-time performance.

Key words: Hierarchical Mobile IPv6(HMIPv6) protocol, handover, Mobility Anchor Point(MAP)

摘要： 分层移动IPv6(HMIPv6)作为移动IPv6的一种改进技术用于解决宏移动和微移动之间的切换管理问题。针对移动锚点(MAP)的选取不合理造成移动节点服务时延增加、MAP负载过于集中等问题，提出HMIPv6的授权给临时移动锚点(LT-TMAP)快速切换方案，在理论上描述该实现过程。仿真结果表明该方案能够更有效地利用网络的MAP资源，具有更好的实时性，提高了切换效率。
