摘　　要：如何合理地利用有限的无线资源,保证链路里传输的各种业务的QoS,同时提供较低的操作和管理开销,从而保证实现B3G系统中的新业务的发展,是无线资源分配策略设计的重点。提供了B3G系统中一种新的无线资源分配策略,并利用OPNET Modeler建立了一个仿真平台对协议算法进行了验证。仿真结果显示,该策略具有很高的资源分配效率,并能针对不同业务的不同需求提供不同的时延保障,对B3G系统QoS框架中的3种业务都能提供良好的支持,并已应用于B3G原型系统。The key of radio resource allocation includes reasonable utilization of the limited bandwidth, guarantee of the quality of various services in the link, and the lower cost of operation and management, which assure the development of new applications in B3G system. A novel method for radio resource allocation is proposed for B3G system and simulated via OPNET Modeler. The numerical calculation results show that this method can satisfy high efficiency of bandwidth allocation, and provide diverse transmission delay assurance for varied services with differentiated requirements under the QoS frame of the B3G system .The new method has been applied to the B3G prototype system.
