摘　　要：针对资源有限的无线异构网络,关键问题是如何管理稀缺的无线资源(如带宽)来满足服务提供者和享受服务的用户的需求。提出一种联合带宽动态分配,准入控制的垂直切换算法,旨在提高运营商的利益最大化的同时兼顾用户的服务质量。仿真结果表明,该算法可以有效地提高带宽资源的利用率,有效降低阻塞率和掉话率,能够满足不同业务的切换要求,适合异构无线网络的多业务传输。In view of the resource-limited heterogeneous wireless network, the key problem is how to manage the scarce wireless resources （such as bandwidth） to meet the needs of users and service provider. This paper puts lbrward a vertical handoff algorithm which joint dynamic bandwidth allocation, admission control. It aims to maximize the benefits of the operators and improve user＇s service quality. The simulation results show that the algorithm can effectively improve the utilization rate of bandwidth resources, and effectively reduce the blocking rate and dropping rate. It is also suitable for multi-service transport for heterogeneous wireless networks and meets the switching requirements ofdifferent business.

关 键 词：无线异构网络 垂直切换 资源管理 带宽动态分配
