Powerful Performance Analysis

The Nastar WCDMA offers more than 30 types of theme analysison the following major network issues, including:

Performance Query

TOP N QueryPerformance Report

CHR Analysis



10/35

Performance Query provides flexibility query means to find any statistics counter that you

want.

1. Default theme analysis

2. Customized theme analysis

Performance Query


Note：A theme analysis is a table that composed of various correlated

traffic statistics counters.


11/35

How to make default theme analysis

For example: TOP N cell call drop analysis

Step1: right click “TopN Cell Call Drop Analysis”，select “Execute”



12/35

Step2: select the begin data and end data and time statistics granularity in Time Range sheet



13/35

Step3: select the query object, it includes 2 types which one is network element the other is

network group. Click OK



14/35

Step4: output the sheet to excel to further analysis

Comprehensive Performance Report

The Nastar WCDMA provides a panoramic view ofthe network performance through the routinenetwork monitoring.

The following three reports contains the regularreports:

Network monitoring reportRNC weekly reportRNC daily report

In the Nastar WCDMA, you can also edit the reportwith the flexible re ort interface.

Solutions to Pilot Pollution

The pilot pollution analysis is based on theanalysis of the configuration parameters, CHR,and the engineering parameter. The analysisresult can be displayed on the map or exported

for further analysis.

For pilot pollution analysis, the Nastar WCDMAprovides the following functions:

Pilot pollution area statisticsCell wireless quality analysis


Pilot pollution on mapPilot pollution analysis report

√ √ The pilot pollution and coverage leak can be foundThe pilot pollution and coverage leak can be foundthrough background analysis. In this way, thethrough background analysis. In this way, the

1. Check the historical trend of RRC setup through RRC setup analysis.

Low RRC setup rate



28/35

2. List TopN Worst Cells Concerning RRC Setup Through Second Query.

Worst Cells



29/35

3. Conduct Second Query on the Worst Cells to find Reasons for RRC Rejection.


Locating Problems:

The RRC rejection isdue to powercongestion.


30/35

4. Solution

The reasons for RRC setup rejection due to resource congestion.

RRC_REJ_POWER_CONG_CELL：

In this case, the RRC setup rejection is due to thepower congestion. It is means the configuration of CAC parameters should be considered

whether it is reasonable, if this indicator is always high, it is means that the cell load

reaches the threshold. The network needs expansion or balancing the load.

1. Right-click on the RNC Daily Report and choose the Execute option.

2. Set the date in the Generate Performance Report dialog box.To generate the daily report, the begin date should be as same as the end date.

Call drop rateexceeds thethreshold

3. Focus the mains reasons of CS call drop on the Top10 worst cells.


RNC releases the RAB,which is triggered by theRF failure in CS domain(synchronization failure on

the uplink)


33/35

4. Solution

In this case, we can find the main reason of CS call drop is due to UL synchronization

failure. It should be cause by some problem of coverage or neighbour list missing or

abnormal handover parameters, we recommends to check these.

If the problem still exist after check all parameters, the next step is analyze the

engineering parameters to improve the coverage, for example, adjust the down tilt and


azimuth of the antenna.

If the adjustment in antenna cannot remove the coverage hole, we recommend to add

more sites or repeaters.


34/35

5. After the optimization, generate the RNC Weekly Report to check the KPI performance.


A ter t e optimization onthe worst cells, the call

access rate in the CS orPS domain increases andcall drop rate decreases.
