适用于cdma2000 1x 无线矿用网络中的接纳控制算法

Suitable call admission control scheme for cdma2000 1x mineral system

在cdma2000 1x矿用系统中,现场视频及数据采集等反向分组应用需求占据着重要地位。这些分组应用的高速率需求需要较高的反向发射功率支持,这必将在反向链路给其它用户带来更大的干扰。采用具有干扰控制功能的接纳控制算法对于系统的稳定高效运行非常关键。在详细分析反向链路中的干扰构成基础上,以满足各种业务信道的QoS需求及系统的ROT限制为目标,提出一种实用的基于ROT的接纳控制算法。

In the cdma2000 1x mineral system,reverse packet data applications,such as spot video and environmental data collection are very important.These reverse data services,which need high reverse data rate,would produce severe interference to other users on the reverse link. To obtain a stable and efficient system,a Call Admission Control（CAC） scheme with reverse interference control is preferred.After a detailed analysis of the composing of reverse interferenee,a practical call admission control scheme basing on ROT is proposed in order to satisfy the Quality of Service （QoS） requirement of each traffic channel and the ROT limit of the system.
