摘要 文章研究QoS优化下WCDMA系统的上行接入控制算法。从QoS分层结构,可度量参数出发,结合新用户呼叫到达率和用户切换到达率,提出WCDMA上行信号呼叫接入控制算法,考虑和平衡新接入用户阻塞率和已接入用户中断率。通过满足不同业务需要的QoS优化策略来控制上行允许接入用户,从而保证系统有稳定的通信质量。仿真分析结果表明,文中给出算法使系统阻塞率和掉话率下降,系统性能得到改善。 In this paper, call admission control algorithm for WCDMAwith QoS optimization is studied. UMTRS QoS architecture is used to analyze the new call arrival rate and handoff arrival rate. CAC strategies for WCDMA uplink are considered, thus to balance the call blocking probability and handoff failure probability for different kinds of QoS traffic. Simulation results show that the call blocking probability and handoff failure probability are decreased and the system performance improved.
