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 0 Mbit/s
The new generation of cellular mobile communication systems require support for a wide range of services, from high-quality, interactive real-time services to fully reliable services over TCP connections. For existing wireless links, the increase of various services of users causes the relative use imbalance of radio resources, which greatly reduces the throughput of the wireless network. This paper presents a new generation of cellular communication based on the wireless resource allocation program, and use OPNET to establish a simulation platform to verify the program. The simulation results show that all kinds of services with different priority levels can get satisfactory quality of service, and the total link throughput reaches 100 Mbit / s
