摘　　要：新一代的蜂窝移动通信系统要求支持多种业务,从高质量的交互式实时业务到基于TCP连接的完全可靠服务。对于现有的无线链路,用户各种业务量的增加造成无线资源相对使用不平衡,大大降低了无线网络的吞吐量。本文提出了一种基于新一代蜂窝通信的无线资源分配方案,并利用OPNET建立仿真平台对该方案进行验证。仿真结果表明,各种不同优先等级的业务都能得到自己满意的服务质量,链路总的吞吐量达到了1 0 0The next generation of cellular mobile communication system is required to support various of applications, from the high quality of interactive Real-time traffics to the reliable services based on TCP link. For the current wireless network, the increment of user's application requests result in unbalance usage with the wireless bandwidth. In this paper we propose a Wireless Resources Allocation approach in Cellular BMW communication system, and then we validated the protocols and algorithms with the software of OPNET Modeler. From the result of emulating we could found that under the term of limited bandwidth, all kinds of applications can be served satisfactorily, and the whole throughput reaches 100Mbit/s.
