中文摘要：

由于无线网络的有限带宽和可变信道，使得无线网络业务的服务质量保证比有线网络更加困难．通过对无线网络业务超阈值数据采用方差分析法构造阈值v的偏差函数，为阈值选取提供一定的依据；通过对无线网络业务到达数据对阈值穿越强度的计算，验证了该方法在阈值选取方面的有效性．可以根据该阈值实现对无线网络业务的控制，提供更好的服务质量保证．

英文摘要：

It is difficult to obtain the guaranteed quality of service （QoS） in wireless networks, because of its limited bandwidth and variable channel. Network traffic prediction is important for network control and allocation. In this paper the deviation tunction of a threshold value is constructed by the method of variance analysis for wireless network traffic, which is essential for selection of the threshold value. According to the threshold- crossing theory, the efficiency of the solution is validated by calculating the crossing intensity. The traffic can be controlled by the threshold value and the guaranteed QoS can be obtained.
