Abstract
As the i-mode service grows in popularity, the i-mode traffic carried by the Personal Digital Cellular-Packet (PDC-P) mobile communication network is increasing rapidly. To meet this growing demand, the switching systems currently in place are being either increased in capacity or replaced by more powerful ones. To plan this effectively, it is necessary to make an accurate evaluation of the i-mode processing capacity. We have developed a new method of evaluating processing capacity using a formula for estimating the CPU occupancy by regression analysis, which takes account of the characteristics specific to the PDC-P network. The formula is to be applied to the commercial environment. It is important to maintain the accuracy of the evaluation above a certain level even when the traffic pattern changes greatly as a result of the future introduction of diverse services. This paper discusses the method of evaluating the processing capacity of switching systems used in the PDC-Packet mobile network. The discussion includes how to deal with differences between the CPU occupancy calculated using this technique and the actual CPU occupancy measured on a commercial switching system.
随着i-mode业务的日益普及,pc - p (Personal Digital cellular packet)移动通信网承载的i-mode业务量迅速增长。为了满足这种不断增长的需求,现有的交换系统要么增加容量,要么被更强大的系统取代。为了有效地进行规划,有必要对i-mode处理能力进行准确的评估。我们开发了一种利用回归分析估算CPU占用的公式来评估处理能力的新方法,该方法考虑了PDC-P网络的特定特征。这个公式将适用于商业环境。即使在未来引入各种服务导致流量模式发生巨大变化的情况下,保持评估的准确性在一定水平以上也是很重要的。本文讨论了PDC-Packet移动网络中交换系统处理能力的评估方法。讨论包括如何处理使用该技术计算的CPU占用率与在商业交换系统上测量的实际CPU占用率之间的差异。
