在无线移动的网络中，出现了两个主要问题：无线层的不良性能和用户移动性的影响。在第三代移动的系统中，CDMA技术的应用解决了无线带宽受限和无线信道误码等问题。终端移动性在呼叫许可控制中引起问题，因为小区中活动的移动的终端的数量是随机变量。在本文中，我们介绍了一种新的方法来预测每个小区中的终端数。基于该信息，可以应用更有效的CAC算法以确保用户的满意度。
In a wireless mobile network, two major problems arise: the poor performance of the wireless layer and the effect of user mobility. The problems related to limited available radio bandwidth and radio channel errors seem to be solved by CDMA technique applied in 3G mobile systems. Terminal mobility causes problems in call admission control because the number of active mobile terminals in a cell is a random variable. In this paper we introduce a new method to predict the number of terminals in each cell. Based on this information a more effective CAC algorithm can be applied in order to ensure user's satisfaction.
