    In this paper, the traffic performance of the base station (BS) in the CDMA Mobile System (CMS) is analyzed, and the simulation results are compared with the analytical results. Also, the bottleneck points and problems which may occur in the BS are pointed out. For analyzing the traffic capacity, the major parameters for the modeling the BS are extracted and the simulation model for the BS is suggested. The simulation results are estimated by finding major objective factors such as the blocking probability, the utilization ratio and the delay time in the traffic channel elements (TCEs), the CDMA interconnection network (CIN) packet router, the base transceiver subsystem (BTS) interconnection network (BIN)-CIN trunks and the transcoding channels. utilization ratio of the BIN-CIN trunks but also the utilization ratio of the CIN are also estimated in this paper. In addition to simulation results, they are compared with the analytical results for validation. This paper is organized as follows. The BS architecture for the traffic performance simulation is described in Section 2. The procedures of mobile calls about originating calls and handoff requests are described in Section 3. The simulation parameters and the simulation model for the BS are suggested in Section 4. The simulation results are analyzed and they are compared with the analytical results in Section 5. Section 6 contains concluding remarks.
