中文摘要: 当前，大多数垂直切换技术都是通过网络层和链路层信息做出切换判决的，然而这种切换判决并不全面，因为它对网络成本、服务类型的考虑不够全面，特别是很难满足用户偏好。提出了一种考虑用户偏爱的切换判决算法(FHMIPv6 with user Preferences,P-FHMIPv6)，通过应用层和网络层之间的切换判决模块来控制切换；结合多播和缓存等机制，来满足复杂网络环境下多种服务的切换要求；同时采用切换定时算法来提高切换性能。

Abstract:Currently, most of the handover decisions are made based on the information of IP layer and link layer. However, they do not consider network costs and the type of services, especially the users’ preferences. This paper proposes a handover decision algorithm considering users’ preferences(FHMIPv6 with user Preferences, P-FHMIPv6). The handover decision is made by the module located between IP layer and link layer. Multicast and caching mechanisms are applied to meet the requirements of the handover decision in complex networks. The handover Timing algorithm is also applied to improve the handover performance.
