摘　　要：基于3G系统的时分同步码分多址(TD-SCDMA)集群通信系统,可以承载不同类型的集群多媒体业务,并能够为用户提供服务质量(QoS)保证。结合各种多媒体业务的特点和集群主叫用户的特征,在传统呼叫接纳控制(CAC)算法的基础上给出了一种基于降速的集群主叫用户CAC算法,通过传统算法与所给算法的仿真比较,验证了所给CAC算法的有效性。TD-SCDMA trunking communication system based on the third generation mobile communication system can carry different types of trunking services, which also can provide users with QoS guarantees. A new CAC is given based on traditional CAC which is on the condition of degradation by combining of multimedia features and characteristics of the trunking caller user. The effectiveness of the new CAC is verified by simulating both of CAC algorithms.
