摘要

针对多媒体业务的CAC(call admission control)策略

给出了宽带CDMA(code division multiple access)网络中非理想功率控制下和外小区干扰因子对系统容量的影响分析。针对语音、视频和数据等多媒体业务的QoS(quality of service)要求

给出了一种基于QoS保证的CAC策略。仿真结果表明

非理想功率控制对系统容量有显著的影响

该策略能有效地保证不同业务的QoS需求

并明显地提高系统资源利用率。

Abstract

Putting forward the CAC schemes with imperfect power control for multimedia traffic would be great signifi-cant.The system capacity with imperfect power control and the other-cell to intra-cell interference factor was analyzed.And then considering the voice/video/data multimedia traffic scenario

a novel QoS（quality of service） based on CAC scheme was proposed.The simulation results show that the system capacity is heavily affected by the imperfect power control

and the proposed scheme can guarantee the QoS for different traffic efficiently

and improves the resource utility significantly.
