摘要
针对战术移动环境下用户进行跨区切换时服务质量(Quality of Service,QoS)会话恢复时延过大的问题,基于快速切换移动IPv6(Fast Handovers for Mobile IPv6,FMIPv6)框架,通过扩展切换初始化(Handover Initiate,HI)消息,使其能够携带Qo S对象信息,从而实现移动管理过程和资源预留协商过程的合并,通过引入提前预留和公共路径利用机制,进一步优化服务质量会话协商过程。理论分析表明,设计的方案可以显著降低服务质量会话恢复时延。
In tactical mobile environment, the cross-area handover by mobile users would result in large recovery delay for QoS sessions. Based on fast-handover mobile IPv6 frame and by expanding HI（handover initiate） message and making it possible to carry the QoS object information, the combination of the fast handoff process and resource reservation process is realized, and by introducing such new mechanisms as advanced resource reservation, and public path using etc., the negotiation process of QoS session is further optimized. Experiment and theoretic analysis indicate that this proposed scheme could significantly reduce the recovery delay of QoS session.
