摘　　要：接纳控制最重要的目的是保证已有连接的QoS,以及满足小区规划的覆盖范围。根据TD-SCDMA负荷和BNR概念,提出了一种基于信道切换接纳控制算法,并对信道切换时上行码道的分配状况进行了分析。仿真结果表明,该算法可显著提高系统服务质量。The objectives of call admission control are to maximize the capacity in TD-SCDMA system and maintain the requested QoS and coverage for individual connections, In this paper, an uplink admission control mechanism based on TD-SCDMA load and BNR is proposed for TD- SCDMA system. This paper analyzes the allocation of uplink code in the case of channel switch, The simulation results show that the proposed algorithm can improve the system performance.
