摘　　要：全IP移动网络中的QoS是最近的研究热点之一,其中资源预留协议(Resource ReserVation Protocol,RSVP)是一个关键技术。为了保证切换时的QoS,需要进行资源预留。针对RSVP不适应移动环境的缺点,文中在全IP移动网络的接入网的微移动域中,提出一种动态资源预留的QoS解决方案,实现微移动协议和RSVP协议之间的互操作。当有多个移动主机需要进行预留时,需要对它们进行优先级排序。文中提出了一种在全IP移动网络中基于信令预测优先级排队的动态排序算法,以有效地对多个移动主机进行资源预留。仿真结果表明文中提出的算法的有效性。QoS in all- IP mobile network is one of the hottest topics recently,while RSVP protocol is a key technology. It is necessary to reserve resource to guarantee QoS during handoff. As RSVP is not applicable in mobile environment, an in - advance dynamic resource reservation mechanism is introduced, which realizes the co- operation of micro - mobility protocols and RSVP. Priority ordering is important when many mobile hosts need to reserve resource. A dynamic ordering algorithm is presented based on signal prediction priority queuing （SPPQ） to efficiently reserve resource for many mobile hosts. Simulation result shows that the presented algorithm is effective.
