摘　　要：移动性管理和服务质量(QoS)保证一直是移动通信网络中两个关键性问题。文章介绍了全IP移动通信网接入网部分的几种QoS实现机制,通过扩展QoS保证机制与微移动管理协议之间的耦合,提出了一种资源预留协议(RSVP)和Hawaii协议松耦合的方案,并以集成了RSVP和Hawaii的仿真平台对该方案进行了仿真。仿真结果表明,松耦合方案可以显著地提高切换过程中的QoS。The mobility management and guaranteed QoS play key roles in wireless networks. In this article, some QoS implementation mechanisms of the access network in All-IP mobile communication networks are introduced first. A new QoS solution of loosely coupling Resource Reservation Protocol (RSVP) and Hawaii Protocol is then proposed by extending the coupling between the QoS guarantee mechanism and micro-mobility management protocol. In order to analyze its applicability, a simulation platform based on NS2 is developed. The simulation results indicate that the solution can greatly improve QoS during handovers.
