The Genex Assistant is a post-data collection analysis tool which are part of the Genex series that works with many systems, such as GSM,WCDMA,WiMAX and LTE.

Assistant enables network planning engineers and network optimization engineers to learn about network performance clearly, locate network problems quickly, improve work efficiency, and reduce the operational expenditure (OPEX) of operators.

The Genex Assistant processes data automatically, analyze and quickly collects the statistics of data, and generates reports according to the preset analysis requirements.

Genex Assistant Data Analysis and KPI Report Procedure4. Go to “Overview” to ge t the KPI va lues .

5. For Successful Setup Rate : Please take the va lues directly from Accessibility > ERAB Setup Success Rate(%)

6. For Minimum FTP Guarantee FTP DL/UL:

Please take the va lues from

Service Integrity > FTP DL App. Throughput Avg(kbit/s)

Service Integrity > FTP UL App. Throughput Avg(kbit/s)

7. For Mobility(HSR) : P lease take the va lues from

Mobility>Intra Frequency Handover Success Rate

8. For Session Establishment Delay: Take the va lues from

Delay>Attach Success Time Delay Avg(ms)


21

Genex Assistant Data Analysis and KPI Report Procedure9. For the Coverage Probability(85% RSRP>-110dBm&SINR>-3dB)

Click on IE Tab.

Go to “Serving and Neighboring Cells” and expand it.

Right click the selected parameters in red box and display on map to show the coverage plot / display on caky to get the KPI values for coverage satisfying the conditions committed to the customer.

10. For Hand off: The values should be taken from

Delay - > HO - > LTE Inter Frequency HO Time Delay right click on it and Display on sheet and export it to excel.

Suggestion:

In Excel use Left(datetime of LTE Intra Frequency HO Time,20) to get the minutes information, and then use countif to calculate the times of LTE Intra Frequency HO Time in each minute.


22

Genex Assistant Data Analysis and KPI Report Procedure11. For the Burst Error Rate(BER) and Drop Session Rate(DSR)

We need to do filte r : SINR: 3dB,RSRP: -95dBm

Click on “Configura tion > Project Se tting > Filte r > Add.

Then input Serving RSRP: > -95dBm and Average SINR > 3dB, then click “OK”.

Go back to Analysis Group, right click it then Run Analysis aga in.


23

Genex Assistant Data Analysis and KPI Report Procedure12. After Run Analysis in Filter mode, now you can get the BER values :

Go to IE > LTE > BLER > DL > Code 0 Residual BLER(%), Display on shee t export it to exce l and ge t the average va lue .


24

Genex Assistant Data Analysis and KPI Report Procedure13. After Run Analysis in Filter mode, now you can get the Drop Session Rate(DSR%) values :

Go to View > KPI Result > Retainability > Session Drop Rate(%).

KPI Stationary Test

Cell edge coverage probabilityFor the cell edge coverage probability, select 20 edge points (SINR is higher than 0dB but lower than 5dB &

RSRP is lower than -95dB) to perform ftp download, each point last 1 min. Record the detail coordinates and test results.The RSRP and SINR must be check from Probe, you can use test plan to download and take a Snapshots.

Ce ll e d g e a va ila bility= s uc c e s s ful p o ints /2 0 *1 0 0 %

Maximum Round trip Delay and JitterFor the Maximum round trip latency, select 1 edge point to perform the ping test. This point must be meet the

condition of -100<RSRP<-90.The ping packet size is 32KB and the ping repeat time is 100. Record the average ping delay. This test should be implemented for 20% of sectors per cluster.

Acc e p ta ble range: the average value is less than 60 ms

Ta rg e t range: the average value is less than 50 ms

Calculate the maximum jitter based on above ping result. 5 biggest jitter values can be canceled. This test should be implemented for 20% of sectors per cluster.

Sector Level – Average Downstream/Upstream Throughput

To the average downstream/upstream throughput (sector level), Use 2 Terminal to perform the ftp download/ upload for 1 min at the same time.

One point (good point) must be get 64 QAM (higher than MCS16 in probe, and RANK2 SINR1 should be between 13 and 18.

The other point (bad point) You have to look at your MCS here. MCS must be 16 QAM (i.e. MCS10 to MCS16)

Please note that your combined DL and UL Throughputs should met the following criteria:

DL:UL (2:2 Configuration)

At good point should be able to get higher than 45 Mbps when downloading alone, and higher than 20 Mbps when downloading in parallel with User-1.

At bad point should be able to get higher than 20 Mbps when downloading alone, and higher than 15 Mbps when downloading in parallel with User-2

The combined DL Throughput (User1+User2) should be between 35Mbps and 40Mbps

The combined UL Throughput (user1+user2) should be between 17Mbps and 20Mbps

DL:UL (3:1 Configuration)

The combined DL Throughput (user1+user2) should be between 40Mbps and 45Mbps

The combined UL Throughput (user1+user2) should be between 7Mbps and 8Mbps

This test should be implemented for 20% of sectors per cluster.


27


Terminal Level – Average Downstream/Upstream Throughput

For average Downstream/Upstream Throughput (Terminal Level).

Select 3 points of one sector (RSRP=-105~-95 / -95~-80/ >-80、 SINR=0~10/15~25/25~35) to perform the ftp download/ upload for 1 min. Record the average throughput of the 3 points. This test should be implemented for 20% of sectors per cluster.

Please pay more attention to 3 points:

RSRP=-105~-95, SINR=0~10, keep the DL throughput between 5M to 15M

RSRP=-95~-80, SINR=15~25, keep the DL throughput between 25M to 35M

RSRP>-80, SINR=25~35, keep the DL throughput between 45M to 55M

DL Average Throughput:

Acceptable range: the result should higher than 4 Mbps ;

Target range: the result should higher than 4 Mbps;

UL Average Throughput:

Acceptable range: the result should higher than 1 Mbps ;

Target range: the result should higher than 1 Mbps ;

This test should be implemented for 20% of sectors per cluster.
