Planning




A. Moving Test Method & KPIA. Moving Test

KPI to look into-KPI01 - Intra-HO : => 98%

KPI02 - EUTRAN Call Drop <=2%

KPI03 - SINR : =>2dB, =>96%

(Log file naming format:- <ddmmyyyy>_<Sitename>_FMv_D<1/2>_<1/2/3/4/5…>

Example:- 31082013_ Angke Kusuma M-S-RT _FMv_D1_1)

1. Login to FTP Server using Filezilla and select

multiple file for DL.

2. Begin DT in clockwise & anti-clockwise

directions at least in two different file.

3. Save the DT log, cross check all KPI achieved.

Ensure naming of log are correct

Other AwareCross check on cross feeder / swap

sector problem during moving test.Capture and report to Huawei if any.

4. Fill up the KPI excel sheet, submit to Huawei

within 24 hours

FTP Server:IP : 10.255.1.2

B1 Static Test – Attach Setup Time

B1. Attach Setup

Time

B. Static Test

1. Choose a good spot (RSRP > 85dBm, SINR > 20dB)

2. Perform Attach Connection TimeTest, run test plan.

(refer attachment)

3. Save the DT log, cross check all KPI achieved. Ensure

naming of log are correct

4. Fill up the KPI excel sheet, submit to Huawei within

24 hours

KPI to look into-KPI04 – Ave. Attach Connection

Time : <500ms

KPI05 – Attach SR : => 98%

KPI06 – RRC SSR : => 98%

Other AwareEnsure 20 attach samples made.

(Log file naming format:- <ddmmyyyy>_<Sitename>_Att_S<1/2/3>

Example:- 31082013_ Angke Kusuma M-S-RT _Att_S1)

Test Plan:




B2. EPS Bearer

Setup Time

B2 Static Test – EPS Bearer Setup Time


2. Perform EPS Bearer Setup Test, run test plan.(refer attachment)




24 hours

KPI to look into-KPI06 – EPS Setup Time : <=105ms

Other AwareEnsure 10 samples made.

(Log file naming format:- <ddmmyyyy>_<Sitename>_I2A_S<1/2/3>)

Example:- 31082013_ Angke Kusuma M-S-RT _I2A_S1)

B. Static Test

Test Plan:




B3 Static Test – Ping TestB. Static Test

B3. Ping Test


2. Perform Ping Test using CMD from Window.

3. Screen shot the result, ensure KPI achieved.


24 hours

KPI to look into-KPI07 – Ping Latency: <=30ms

Other Aware- Ensure 100 samples made.

- Ensure screen shot as below:

Ping command:-

a. ping 10.1.12.49 –n100

b. ping 10.1.12.105 –n 100

(Screen shot naming format:- <ddmmyyyy>_<Sitename>_Ping_S<1/2/3>)

Example:- 31082013_ Angke Kusuma M-S-RT _Ping_S1)




B4 Static Test – Static FTP UL & DL TestB. Static Test

1. Choose 3 different location; Near, Middle, Far

2. Perform FTP DL & FTP UL Test over Filezilla.


24 hours

KPI to look into-KPI08 FTP DL (Near) – 90% => 55Mbps

KPI09 FTP UL (Near) – 90% => 7Mbps

Other Aware- Ensure Multiple tread DL / UL.

- Ensure DL / UL more than 120sec / 2min- Near (SINR >= 25 dB) / Middle (15 dB =<

SINR < 25 dB) / Far (SINR < 15 dB)

(Log file naming format :- <ddmmyyyy>_<Sitename>_FTP_<DL/UL>_<Nr/Md/Fr>_S<1/2/3>

Example:- 31082013_ Angke Kusuma M-S-RT_FTP_DL_Nr _S1)

B4. Static FTP UL

& DL Test

B5 Static Test – Speed TestB. Static Test

1. Choose 3 different location; Near, Middle, Far

2. Perform Speedtest at www.speedtest.net


24 hours

KPI to look into-N/A (ensure the throughput at near is

“readable”

Other Aware-Ensure correct server are chosen

- Near (SINR >= 25 dB) / Middle (15 dB =<

SINR < 25 dB) / Far (SINR < 15 dB)

-Ensure screenshot correct as below:-

(Screen shot naming format:- <ddmmyyyy>_<Sitename>_<Inux/Indo/SFren/Telkom>_<Nr/Md/Fr>_S<1/2/3>)

Example:- 31082013_ Angke Kusuma M-S-RT_Inux_Nr _S1)

B5. Speed Test

3. Choose the correct server related to operator for

test. Eg PT.Internux server @ Tangereng

4. Screen shot the result, ensure KPI achieved.




Appendix 1 – Drive Test Basic

Knowledge




Radio Parameter @ GENEX Probe

PCI (Physical Cell Identifier)

Value range : 0 – 839, cross-check any cross

feeder problem when conducting moving

test.

RSRP (Reference Signal Receive Power)

-70 dBm to -90 dBm → Good -91 dBm to -110 dBm → Normal

-110 dBm to -130 dBm → Bad

SINR (Signal to Interference+Noise Ratio)

16 dB to 30 dB

→ Good 1 dB to 15 dB → Normal

-10 dB to 0 dB → Bad
