2G PS power control Parameter tuning

[auto_art]

dear Pl. find the parameter below tuned for HO and PS power control. these settings gave us tremendous improvement. we have implemented across whole network after testing. (release R14. Ps power control is optional feature)

Dear

They are mostly power control related to voice only one I see is PS , it is possible to share the result as Iam doing power for DL PS for EGPRS just improved RX quality.

Hi,


I tried it by myself. It is giving very negligible result in RxQual improvement. In my opinion do not spend your time on it .


Cheers

if i share the results u mite change your mind to re-implement..
things to remember here 2G Ps power control means closed loop powr control not the stone age UL open loop.

POST AFP:PS DTX & PS PWR CTRL & CS Optimization Results:-

this is one prominent BSC highly utilized.

Ø HOSR NBH Improved from 98.04 to 98.61 avg & BAD Cell Count HOSR<95% decreased from 88 to 49 avg
Ø DL RX Quality(0-5)% Improved from97.01to 98.34 avg & BAD Cell Count DL RX Qual<95% decreased from 204 to 55 avg
Ø TCH DCR NBH Improved from .36 to .35 avg & BAD Cell Count <95% decreased from 20 to 15 avg
Ø TASR NBH improved from99.11to 99.16 avg & BAD Cell Count <95% decreased from 25 to17 avg

Hi,

yes mate , share your result i may change my opinion. I am aware about UL and DL power control

DL PS power control in E/// introduced since release G12 around 1.5 year ago . Will be waiting your complete report in regard.

[fannakhosr]

could you please elaborate more on parameter name as I search in alex g12 and 11B, but not find those parameters in the library

dear this is for Huawei

I am really in doubt about HOSR 98.04 to 98.61 improvement. If you have chance please share benchmark result of KPIs. Then it will be more clear.

do you need pre post KPI trending.?
