Summary

The pilot project was done on RNC14

Final comparison was done between the baseline and

the optimized values

Baseline values are between 19thand 24thApril

Optimized values are between 9thand 12thApril

Dates between 13thand 18thApril are excluded because

the revert back was not done successfully in one shot

and was completed on 18thApril

Some KPIs for 22ndApril gave very high values that is

not correct so we used same 21stApril values for those

KPIs

These KPIs are: CSFR, CS CSFR, PS CSFR, RRC

Conn Failure Rate

Number of calls

OPT ORG

More CS calls

CS Traffic

OPT ORG

KPI ORG OPT GAIN

CS Traffic (Erl*hour) 14806 14308 -3.36%

An increase of CS traffic should be expected due to the increase in the

number of CS call. CS call duration even though there are more CS calls

due to IRAT HO. In average, the CS calls go faster to 2G

PS Traffic

OPT ORG

KPI ORG OPT GAIN

PS Traffic (Erl*hour) 164398 133929 -18.53%

Traffic increased just after the optimized period even before completing

the reversion.

HSDPA quality was improved as part of the optimization exercise

CS DCR

OPT ORG

Values in CS DCR are quite low and the difference between periods is 0.04

IRAT HO could have caused this behavior as Optimi tried to retain morecalls in 3G

Replacement Ratio

OPT ORG

KPI ORG OPT GAIN

Replacement Ratio (%) 20.93 18.15 13.26%

In the original period it seems that more pilot pollution is there. More sites

(more overlapping) are on air now so the value is even higher than in the

beginning of February

HSDPA HO Fail Rate

OPT ORG

KPI ORG OPT GAIN

HSDPA HO Fail Rate (%) 1.37 0.64 53.23%

Less HO Failure Rate is better perceived by the user

23

HS to DCH HO Rate

OPT ORG

KPI ORG OPT GAIN

HS To DCH HO Rate 0.24 0.08 67.85%

In the optimized period the total throughput was better as, overall, the call

was more on HSDPA than in DCH. In bad coverage areas the calls go to

DCH normally

More sites could

have made this

value higher

than in Feb
