摘　　要：随着GPRS/GSM移动接入网的广泛应用,有效的信道分配算法在保证网络服务质量中的重要性开始凸现。该文描述了GPRS/GSM移动接入网的信道分配过程,对固定信道分配算法和动态信道分配算法进行了详细分析,并采用自行开发的GPRS/GSM网络仿真软件模拟语音业务与分组数据业务动态共享信道资源的过程,从而比较了不同的信道分配算法对接入网服务质量的影响,结果显示动态信道分配方案在增加系统运算量的同时可以很好地支持网络通信的质量。With the wide application of GPRS/GSM mobile access network,the efficient channel allocation algorithm has shown importance in supporting the quality of network service.In this paper the procedure of channel allocation in GPRS/GSM mobile access network is described.The fined channel allocation algorithm and dynamic channel allocation algorithm are analyzed in detail.The influences which are imposed by the different channel allocation algorithms on the quality of the access network service are compared with each other through the software of GPRS/GSM network simulator,which is developed in order to simulate the procedure of the voice service and packet digital service dynamically sharing with the channel resources.The result shows dynamic channel allocation algorithms can support the quality of network communication although they increase the computing load of the system.
