告警对无线网络质量影响现状

1. 简介

整个移动通信网的网元很多，影响网络质量的因素很多包括各个方面。本文主要针对告警对无线网络质量影响现状。

2.具体分析

2.1 主要告警

现网告警可以依据无线通讯系统网原分为不同的级别，如TS、TRX、BCF、BTS、传输、BSC、MSC、VLR、HLR、OMC等级别的告警。

和无线指标有直接关系的告警多为TS、TRX、BCF、BTS、传输、BSC级别的告警。

此类告警也可以分为多个类别，如天线告警、载频故障、基站性能下降告警、传输误码、基站外部告警等等。

以下列出一些主要会影响指标和需要进行即时处理的告警：

2.2 告警对无线指标的影响

各类告警对各个不同的无线指标的影响程度都不相同，其中的关系非常的复杂，是多重交叉互相影响的错综复杂关系。

以下列出一些常见会受告警影响的无线指标： -TCH掉话率 -SDCCH掉话率 -上行通话质量 -下行通话质量 -切换成功率 -阻塞率

-话务量吸收(TRX利用率) -无线干扰

-基站良好率(可用率)
