With the development of the wireless internet, there are more and more mobile terminals. Without mobility management protocol, mobile terminals could not communicate with others terminals when they are away from their home network. Mobile IPv6 was proposed which is host-based mobility management protocol. But it has several drawbacks, such as wireless link resource waste, load or consumption of power in mobile terminal is large. To overcome the weakness of host-based mobility management protocol, network-based mobility management protocol called Proxy Mobile IPv6 (PMIPv6) is standardized by the internet engineering task force network-based localized mobility management working group, and it is starting to attract considerable attentions. Although several proposals have been made for handover and Route Optimization (RO) in PMIPv6, they still need too many communications, do not consider about seamless-handover and RO without out-of-sequence problem simultaneously. In this paper we proposed a time-efficient handover mechanism in PMIPv6 by using the improved RO. We use the characteristic of anycast to achieve the time efficiency. By the mathematical analysis we prove that the proposed protocol has shorter latency and supports faster mobility of the mobile terminals.
