摘　　要：通过分析会话类业务用户行为、集群系统信道分配方式和业务的容量特性,总结出TD-SCDMA集群系统的会话业务模型。针对坎贝尔算法无法准确地描述不同集群业务对容量需求的缺点,提出了一种改进算法,并应用到TD-SCDMA集群业务模型的分析中,得出了会话业务的容量需求。结合不同区域忙时拥塞率、业务忙时话务量及业务呼损制估算出了TD-SCDMA集群基站载波需求数。这些分析和参数的估计对TD集群的初期建网和系统资源配置提供相应的参考依据。Through the analysis of conversational service＇ s user behaviors, channel distribution mode and capacitance properties of trunking system, conversational service model of TD-SCDMA trunking system is summarized. Aiming at the Campbell algorithm＇s shortcomings that can＇t inaccurately describe different services and capacity demand, an improved one is presented and used in TD-SCDMA trunking system to count the capacity demand of conversational servers. According to different region＇s congestion rate and servce＇s traffic in busy hour and the characteristic of call lose system, the carrier number in a base station are estimated. These methods and data summarized in this paper can provide some references for the initial stage of network design and resources distribution in TD-SCDMA trunking communication system.
