HSDPA系统接纳控制策略性能研究

Study of Admission Control Strategies in HSDPA System

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 goal and importance in study of AC algorithm in HSDPA, analyzes the throughput based AC, and discusses in particulare the power-based AC algorithm in HSDPA. It also analyzes and describes the three measurement-based algorithms. Finally, the setting ups of various admission thresholds and different QoS classes are simulated and discussed including their influences on the system performance.
