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. This paper discusses the method of evaluating the processing capacity of switching systems used in the PDC-P 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.
