Very low traffic !!!!

[nevy_14]

Hi,

I think before deciding on whether hardware (alarms, loose connections, etc) or TX issues are a reason for this recorded low traffic, u may need to tell if there are signs subscribers are available to generate more traffic than this.

The easy way for you to do this is fby irst checking counters and KPI's on accessibility to tell on how many attempts are there and out of which which proportion is successful and/or failure.

With too high attempts failing, it's possible there are problems and you'll need to start assessing ur system for alarms and radio parameters. Otherwise if most attempts get through successfully, it means that's all the traffic your subscribers can generate in that location and more marketing will be needed to boost up your business.

hi,

just adding ludali, you should check the traffic distribution for each TA (if your problem in GSM). from that you can see if there's any hardware (antenna especially) problem. cmmiw

If the low traffic cell is GSM, then are you using different bands in your network? This can be controlled by the Layer setting. The lower the layer the higher the priority and more subs will be forced onto this site therefore increasing the traffic. Is it a macrocell, microcell, pico or nano? Where is it situated, dense pop area? There could be another umbrella site taking all the traffic which can be shared by CLS if ericcson BSC. If 3G, you can increase CPICH power but then capacity is compromised. If no alarms on cell, then all you have to do is adjust these parameters to make the cell more attractive...increase ACCMIN, BSPWR and BSPWRB.

Check also cell load sharing, CLSLEVEL, CLSACC. Does your cell have MBCCHNO of the neighbouring cells?Pls, check it also.

In some cases in E******* RBSs there is problem on DRUs unit(RBS Type RBS2216,RBS2116)

The problem is in each unit there is 2 TRX and BCCH allocated to 1 TRX it is usually happening in networks this TRX output level will be weak then MS can not access to network(for your information there is no HW alarm in BSC) to understanding ask BSS to shift BCCH carrier to another DRU and then observe .


If traffic increased means your TRX is faulty!

check the geographical area and also check the other 2 sectors traffic.

Experts,
I've in my network cells with very low daily traffic like 0.003 Erlang/day

Which parameters? I should check and optimize...

Give it a Software Reset then analize the stats hourly if not fixed

Give it a Hardware Reset then analize the stats hourly if not solved

propably ..it needs Software upgrade so raise Trouble Ticket so RNC guys and BTS guys can upgrade their software keep analyzing the stats and it will be solved

Hi JUSTDREAM,

Before changing your software parameters, check first the hardwares..if not find anything wrong with your hardwares, collect stats, and compare it with your KPI...then proceed with software parameter change..

Is it 2g/3g? Whats the vendor?
