文中指出了在支持HSDPA接入技术的网络中,研究接纳控制的目的和意义,分析了基于吞吐量的接纳控制算法,着重研究了下行链路上基于功率的接纳控制算法,针对HSDPA系统的特点,分析和阐述了三种基于不同测量值的算法。在仿真中,就多种接纳门限的设定、数据业务QoS是否分级等对系统性能的影响问题进行了分析与说明。 This paper points out the purpose and significance of admission control in HSDPA-enabled networks, and analyzes the throughput-based admission control algorithm. Emphatically studies the power-based admission control algorithm on the downlink. According to the characteristics of HSDPA system , Analyzes and expounds three algorithms based on different measured values. In the simulation, we analyze and explain the influence of the system’s performance on the setting of multiple admission thresholds, whether the data service QoS is graded, and so on.
