【摘要】 在对GSM/GPRS网络中的信道分配、分组数据调度、功率控制、越区切换和链路自适应等机制进行系统仿真的基础上,对一些反映网络性能的主要指标,如阻塞率、掉话率、信道利用率和数据平均传输速率等做出了一定的估计。对不同网络参数和算法对网络性能的影响规律也进行了分析。这为今后网络的优化提供了一定的策略和依据。更多还原

【Abstract】 This paper simulates some mechanism s of GSM/GPRS network on system level,such as channel allocation,packet schedul e,power control,handover,link adaptation,and so on,based on which some main targets reflecting t he network’ s performance,such as blocked ratio,dropped ratio,chan-nel utility,average rate of data tra nsmission can be estimated.The rule s for different network parameters and algorithms how to influence the n etwork’ s performance are analyzed as well.T he result is useful for the network optimization.更多还原
