HSDPA(高速下行链路数据包接入)为WCDMA的增强演化版本犤1犦。提出了基于HSDPA系统中的一种自适应准入控制方案。这里给出的两个性能指标是新呼叫拒绝率(newcallblockingratio)和切换拒绝率(handoffcallblockingratio)。仿真性能的比较对象是固定预留资源分配比例的准入控制方案。仿真结果显示,自适应准入控制方案保证了一定的切换拒绝率,同时降低了新呼叫拒绝率。
HSDPA (High Speed Downlink Packet Access) is an enhanced evolved version of WCDMA 犤 1 犦. An adaptive admission control scheme based on HSDPA system is proposed. The two performance metrics given here are the new call rejection rate and the handoff rate lockout rate. The comparison object of simulation performance is the admission control scheme of fixed reserved resource allocation ratio. The simulation results show that the adaptive admission control scheme ensures a certain handover rejection rate and reduces the rejection rate of new calls.
