Summary
We have to started second cluster optimization on Cluster_6.. Cluster_6 generally contains Kerman Provinces sites.. There are totally 31 NodeB in second cluster.. General problem is High drop rate and low accessibility rate due to some kind of congestion and transmission Link capacity problems..
We have solved congestion problems even Uplink Power congestion and HSUPA User congestion.. After solving of congestion there are PDU retransmission rate is started to deteriorate due to transmission link capacity and link quality problems..

4. OSS KPI Achievement
RNC level improvement achievement
After the solving of all type of congestion of second cluster , Rnc congestion rate and Rnc PS – Cs- Hsdpa – Hsupa Accessibility Rate is improved..

5. Cluster level KPI comparison
Cluster_6 comparison shown in below table..
Note : Hsdpa/Hsupa throughputs are not improved due to there are PDU Retransmission Rate start to deteriorate by the transmission link capacity and link quality.. That issue waiting increment of Link capacity / Bandwidth definition by transmission department..
7. DT results
-
-
DT comparison plots and Issues
-
Here you will put DT plot of before and after test and show the improvement.Or you can show cross connection problems. Or other hardware issues.
-
-
Static Test comparison
-
Here you put Static test comparison to show improvement on throughput of uplink and down link
