The base station(BS) of CDMA Mobile System(CMS) provides mobile call services by controlling call processing functions. The call processing part of the BS is divided into two components; the base station transceiver subsystem(BTS) and the base station controller(BSC). In this paper, we present the call capacity estimation of the BS about control signals and traffic data of calls by the simulation, and find the bottleneck points and problems which may occur in the BS. In order to estimate the call capacity, first we extract the major parameters for the modeling the BS. Second, we suggest the simulation model for the BS. Third, we estimate the simulation results by finding major objective factors such as the blocking probability, the utilization ratio and the delay time in the traffic channel elements (TCEs), the CIN packet router, the BIN-CIN trunks and the transcoding channels. BIN/CIN and BIN-CIN trunks, number of the traffic and transcoding channels. Second we suggest the simulation model about the BS. Third, we estimate the simulation results by finding major objective factors such as the blocking probability and the utilization ratio of the traffic channel elements(TCEs) and the transcoding channels. And not only the average delay time and the utilization ratio of the BIN-CIN trunks but also the utilization ratio of the CIN are estimated in this paper. This paper is organized as follows. Section 2 describes the BS configuration for the basis of call capacity simulation. Section 3 describes the procedure of mobile calls. Section 4 extracts the parameters used for the modeling and suggests the BS simulation model. Section 5 analyzes the simulation results and estimates the call capacity, and points out some problems of the BS. Section 6 concludes this paper.
