摘　　要：随着信息量的膨胀 ,在今后的移动通信中 ,数据业务将会占主导地位 ,对数据业务的处理方式也将多样化。而GPRS业务将因其所要求的服务质量的不同而分为不同的等级。将设计 1个模型对两种不同的优先级业务处理方案进行仿真 ,通过话音掉线率、话音阻断率这两个参数来衡量高优先级业务对系统的影响。结论表明 ,高优先级数据业务的引入使话音阻断率升高 ,使话音的掉线率上升。因此 ,运营商在对信道资源进行分配时和资费收取时 。With the explosive incrementof the information,data service will be dominantin the future mobile communication. The way to process the data service will be various,it is required that GPRS service be divided into different priority level for different service quality.We design a model and evaluate the influence ofthe high priority data service by voice dropping probability and voice outage probability.Our study indicates thatthe introduction of high priority data service will increase the voice dropping probability and voice outage probability.So the interference broughtby the special service should be considered when the manager assigns the channel resource and charges it.
