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 ,要考虑这些特殊业务带来的影响
With the expansion of the amount of information, in the future mobile communications, data services will dominate, and data services will also be diversified. GPRS services will be divided into different levels due to the different quality of service they require. We will design a model to simulate two different priority service solutions and measure the impact of high-priority services on the system through the voice dropped rate and voice-off rate. The conclusion shows that the introduction of high-priority data services increases the voice blocking rate and increases the voice dropped rate. Therefore, when allocating channel resources and charging tariffs, operators should consider the impact of these special services
