%X According to circuit-switched conversation service characteristics of wireless channel resources occupancy and call arrival process in TD-SCDMA, a combined call arrival model for voice and videophone service based on two-dimensional markov model is presented and established. Through analysis and simulation test, the relationships between system capacity of TD-SCDMA, arrival rate of traffics and call lost rate of traffics are obtained respectively. Busy traffic can be forecasted using statistical practical traffic. Further more, the request of busy system capacity can be estimated according to the need of call lost rate. The model can be used to wireless resource planning and network optimizing in TD-SCDMA system
