摘要：Proxy Mobile IPv6 has been standardized as a network-based mobility management protocol in the IETF. To optimize mobile node's handover performance, a context of the mobile node such as its identifier, accounting, authentication and authorization states is expected to be transferred between mobility entities. This paper proposes a simple context transfer mechanism named Context Re.ector for Proxy Mobile IPv6 (Context Re.ector). Context Re.ector carries any kinds of information of mobile nodes. With Context Re.ector, the service such as AAA (Authentication, Authorization, and Accounting), ROHC (Robust Header Compression) and QoS (Quality of Service) can be quickly re- established after handover of the mobile node. Therefore, the handover latency and the packet loss during handover can be reduced. Comparisons of Context Re.ector and other approaches make it clear that Context Re.ector is superior in terms of packet loss and handover latency during handover
