中級(jí)培訓(xùn)第一模塊之五常見指令及告警分析1.ppt

常用指令及告警分析,中國移動(dòng)通信集團(tuán)網(wǎng)優(yōu)專家小組,中級(jí)培訓(xùn)第一模塊之五,常用指令及告警分析,MML ： 人機(jī)接口語言. 在 BSC界面上通過人機(jī)接口語言 ，我們就可以直接和BSC下面的網(wǎng)元進(jìn)行“對話”。 指令的使用方法和命令可以參看 NED （ Command Reference Manual ）。 如果不熟悉MML指令，請你使用”?”,可以幫助你知道下一步的指令信息。 S11.5NED對于分析告警也很有用處。 目前NED的版本已經(jīng)很高，但是要求的機(jī)器配置較高，啟動(dòng)較慢，所以S11.5 相對比較實(shí)用。,常用指令及告警分析,常用指令及告警分析,如何使用指令中的幫助,Z?

The antenna adjustment is unbalanced. Calls can still be maintained. This alarm can also be caused by snow and ice on the antenna. AFE Transmitting The antenna filter unit (AFE) combines one or two transmitters to one single transmitting antenna. The AFE also filters transmitter signals to reach better signal quality.,S11.5 Ned Info,MML Alarm info,常見告警分析,Receiving The antenna filter unit (AFE) filters and amplifies the signal received from the receiving antenna. The amplified output signals are connected to the receivers of the BTS. Each AFE contains two low noice amplifiers (LNA), one for the main and one for the diversity receiving path. One LNA contains two different amplifier branches. The LNA is out of order if both of those amplifier branches are faulty.

Replace the faulty unit. The alarm level is adjustable in the HW database. Cancelling Do not cancel the alarm. The system cancels the alarm automatically when the fault has been corrected.,Refer to S11.5 NED Chapter 2.5 Alarm Reference Manual for details !,網(wǎng)管統(tǒng)計(jì)報(bào)告及內(nèi)容簡介,網(wǎng)管統(tǒng)計(jì)報(bào)告及內(nèi)容簡介,通過統(tǒng)計(jì)報(bào)告我們可以觀察網(wǎng)元的運(yùn)行狀況,網(wǎng)管的時(shí)時(shí)性相對較差,增加了網(wǎng)絡(luò)的負(fù)荷,網(wǎng)管統(tǒng)計(jì)報(bào)告及內(nèi)容簡介,網(wǎng)管統(tǒng)計(jì)報(bào)告及內(nèi)容簡介,通過cell doctor可以完成如下工作 : 連續(xù)性檢查 網(wǎng)絡(luò)質(zhì)量檢查 小區(qū)規(guī)劃 接入成功率 網(wǎng)元可用性 干擾 網(wǎng)絡(luò)配置 告警 本地網(wǎng)元,網(wǎng)管統(tǒng)計(jì)報(bào)告及內(nèi)容簡介,Benchmark and analysis 200 Network performance stats per days.
