摘　　要：在漫游情况下,基于3GPP标准网络架构,给出WLAN和HeNB之间一种跨层无缝切换方案。利用FMIPv6的基本思想,在第二层切换之前进行预认证处理,以减少切换的时间延迟。在切换期间,引入存储转发功能,以减少数据包的丢失。仿真分析表明,所给方案在信令开销、切换延迟和数据包丢失方面性能良好。Based on 3GPP standard network architecture in roaming scenario, a cross-layer seamless handoff scheme between WLAN and HeNB is proposed. The basic idea of FMIPv6 is used to perform pre-authentication process before layer 2 handover to reduce handover latency. In addition, the packet buffering and forwarding functions is introduced into the handover period to reduce packet loss. Simulation results show that the proposed scheme performs well in signaling cost, handover latency, and packet loss.
