Drive Route Basics

All sectors to be covered during the test

Carry a hardcopy of the drive route direction, while DT reaches the

Instruct the driver to follow the drive route

Drive Route Guidelines

Best server plot Drive route to be collected by SOLPAR DT engineer from Circle RF Lead before he reaches the site.

All motorable roads covering all three sectors of the site are to be driven. The motorable roads which are not accessible or can’t be driven due to any blockage should be captured with a snapshot for proof.

If SCFT is performed on a standalone site then each sector to be driven up to serving cell RSRP as per morphology in the main lobe as defined in under mentioned table:

Morphology Type Coverage Threshold (RSRP dBm)

Dense Urban -107

Medium Urban -110

Suburban -113

Rural -116

Morphology RSRP levels

Drive Route Guidelines..

If SCFT is done on a site that is not a standalone site and the neighbor site is radiating then the drive route should be done until the handover happens with the neighbor site, but if the Neighbor site is not radiating then the drive should be done until neighbor site.

The stationary test should only be done in the main lobe of serving antenna DT Engineer will instruct the car driver for the direction to be followed based on pre-

defined drive route based on GPS location in drive test tool. Engineer will carry the drive route handmade copy, during the SCFT test.

Drive Test Route Sample

Drive Route Example

Major Road

More than one lane

Important road that leads from

one town or city to another

Minor Road

Summary

Perform regular testing of drive-test UE’s

Preparations for SCFT consist of TSSR review, eNB parameter verification from LSM-R, availability of drive route and checklists. Before proceeding to the site make sure you have these

TSSR gives details about eNB physical parameters such as antenna height, azimuth, tilt, pictures of obstruction, site drawings and map views

LSM-R parameters include details such as VSWR, Tx power and PCI

Ensure FTP connectivity before proceeding to site

Cover all sectors during the drive

Physical Checks at Site

Physical checks during site survey

Physical verification of site with respect to data given in TSSR/Cell ref. Need to check under mentioned points.

Once DT engineer reaches the site he should validate the PCI as seen on field with cell ref file and then perform a walk test around the site in clockwise and anticlockwise direction for checking the inter-sector handover and correct PCI as seen in cell ref: file.

Site location in terms of Lat/Long, Site name and address, Antenna azimuth, Antenna height, Antenna Tilt (Mechanical Tilt), Antenna physical blockage in main/side lobe (if any) & Tower type.

If there is any deviation in actual versus TSSR/Cell ref then SOLPAR engineer will try to rectify it on field with due permission from Samsung RF lead and if he is unable to do so then the same shall be informed to Samsung and the DT should move over to the next site.

If the deviation cannot be corrected as confirmed by Samsung RF lead, then the same has to be updated in site forge by the DT engineer.

Physical checks during site survey

Only after completing physical verification and passing the same SOLPAR engineer will start performing SCFT activity.

In case of tower/antenna access issue from bird nests, honeybees comb etc. the corresponding Samsung area manager should be informed and DT should move to the next site.

SCFT once started should be completed within the same day, until and unless there is some constraint that is making the process shift to other day.

Physical blockage in direction of serving antenna should be noted and snapshot should be taken. The same comment with snaps has to be updated in the SCFT report by SOLPAR project manager. The SCFT has to be carried on however.

Measuring Site Co-ordinates Check the battery of GPS (72 channel GPS)

Point GPS towards clear, open skies for accuracy

GPS Setting time >5 min & GPS number of satellites > 4

Low Battery voltages and rare Geomagnetic storms may result in erroneous GPS readings

GPS should not be used for Ground Elevation readings as the inaccuracy can be well over 30m

Stand in the center of the site location (GBM, RTT,RTP)

Once the satellites are acquired, note co-ordinates for N & W in degree - decimal format.

Update this information into check list for pre-post comparison and for database tracking

Checking Antenna Azimuth

Stand in front of the Antenna

When taking compass readings, keep at least 8m distance from any magnetic, metal, or current carrying structures such as towers, vehicles, or cables for correct readings

Open compass and wait a moment till the compass needle is stationary

Check the antenna azimuth with reference to North & measure the value in degrees

Compare the observed value with the one in the TSSR

In case a mismatch is detected, make corrections on site

Mention the values in the check list for pre-post comparison and for database tracking

Check Azimuth – marking on map

Check the service direction of the antenna

Mark the main serving direction of the antenna on the map

Tower Height Measurement – Laser Meter

Stand on the edge of tower

Press start button and then press “measure” button

Wait for 2-3 minutes or check the ground or building from the built-in binoculars in the laser meter

Press the “measure” button again

Take pictures of the value in meters

Tower Height Measurement - Tape

Drop the measuring tape from the edge of the tower platform

Team member at the ground end will record the value

Antenna Height – RTP / RTT

Antenna Height – GBT / GBM

Compare the value on TSSR with actual result

Correct the Antenna Height if mismatch with TSSR Report

Antenna Mechanical Tilt Measurement

Bring tilt measure in contact with antenna on the back side & center(①)

Adjust the tilt measure (②) to level off (③)

Check tilt of antenna (④), as per the picture red line is on 3rd mark from zero, which means that the tilt is 6 degrees {one mark = 2 degree and consider the bottom scale}

Compare the value on TSSR with actual result

Correct the Mechanical Tilt in case of mismatch with the TSSR Report

Mention the values into check list for pre-post comparison and for database tracking

To change tilt, loosen all nuts, adjust tilt as desired and then tighten them

Drive Test

SCFT Drive Test

After completing physical verification, SOLPAR engineer will start performing drive test.

Drive test to be performed on all motorable roads.

The mobiles need to be attached on car dashboard while doing drive test.

Check FMS server connectivity to site by downloading test scenarios on “XCAL Auto Mobile” over mobile.

SCFT drive test activity has two type of tests.

1. Stationary Test

a. Attach

b. VOLTE Short call

2. Moving Test

a. FTP -DL

b. FTP -UL

Stationary Test ( Alpha Sector)

Drive test engineer will start the drive test activity with stationary test.

Move over to Alpha sector and perform following activities

Latch on alpha sector PCI and RSRP, it should have a stable dominant RSRP level from serving cell, and neighbor cells should not be dominant.

Check GPS status and select destination value of co-ordinates from map window.

Assign “Stationary-1” call setting with Cycle information & site details, (CYCLE should remain the same until the complete SCFT test (STATIONARY & MOVING) ends), if you have to restart the test cause of any issue then issue new and different cycle number, but it should be same for stationary and moving test (ideally it should be incremented by 1, every time you repeat the test on same site), cycle is a reference for naming the log files.

Stationary Test Procedure:

Stationary Test( Alpha Sector)…

Perform under mentioned test by pressing “AUTO CALL” over the s4 mini phone.

. Stationary Test

a. Attach

b. VOLTE Short call

At the end of “Auto call” press status as “In Progress”.

Press “Auto DRM/DRX Upload” button which is popped up & wait for upload to finish.

Stationary Test(Beta Sector)

Drive test engineer now moves over towards Beta sector and performs the following activities during stationary test: Check PCI

Assign “Stationary-2” call setting with cycle information & site details

Perform under mentioned test by pressing “AUTO CALL” over s4 mini handset.

a. Attach

b. VOLTE Short call

At the end of Auto call press status as “In Progress”.

Press “Auto DRM/DRX Upload” button which is popped up & wait for upload to finish.

Stationary Test( Gamma Sector)

Drive test engineer shall move over towards Gamma sector and perform the following activities during the stationary test

Check PCI and latch to it.

Assign “Stationary-3” call setting with cycle information & site details

Perform under mentioned test by pressing “AUTO CALL” over s4 mini handset.

a. Attach

b. VOLTE Short call

At the end of “Auto call” presses status as “Completed”.

Press “Auto DRM/DRX Upload “button which is popped up & wait for upload to finish

Moving Test

After completion of “Stationary” test now the DT has to go for the “Moving test”, drive test engineer will use two S4 mini handsets. There will be two different tests that shall be performed on these handsets. One handset for DTDL One handset for DTUL

“Moving test” call logging should start by performing a walk test around the site in clockwise and anticlockwise direction for checking the inter-sector handover within the SCFT site and checking the correct PCI as seen in cell reference file. Drive test engineer will carry out the remaining part of moving test while in car in a continuous log. Keep checking the PCI of serving cell so as to confirm handover between neighbors of same site. Move from Alpha sector to Beta sector to check handover between them. Move from Beta sector to Gamma sector to check handover between them. Move from Gamma sector to Alpha sector to check handover between them. Move from Alpha sector to Gamma sector to check handover between them. Move from Gamma sector to Beta sector to check handover between them. Move from Beta sector to Alpha sector to check handover between them. Make “Coverage footprint” of each sector in all possible drive routes based on Morphology based RSRP

Levels. After finishing the clockwise / anti-clockwise routes, You must run through DTR (Drive test route) provided

to you by Samsung RF lead

NOTE : Samsung RF lead has to provide DTR based on best server plot , as per example attached below. Or Alternately Samsung RF lead must follow procedures provided by National RF Optimization team to prepare DTR , This is Mandatory

Moving Test…

Important: If handovers are not happening between neighbor cells then stop the drive and call up LSMR engineer for handover definition or any alarms related to the same, and resume the drive, post the resolution of the same.

Press “Stop” after completion of drive on both handset( based on steps

as above) and press status as "Complete” .

Press “Auto DRM/DRX Upload” button which gets popped up in both handset & wait for upload to finish. Ask the LSMR engineer to lock the site. Inform the SOLPAR PM and Samsung area manager about the completion of the drive and move for the next drive if time permits for the day.

Checklist during drive

If any Attach fail, /Access fail, Handover fail, Sector swap are observed during drive test then call should be immediately stopped and LSMR engineer should be contacted for any running alarm. Later fresh drive for the same should be done post rectification.

During drive test and eNB physical verification if any physical obstruction due to which drive couldn’t be done on that road then SOLPAR DT engineer needs to take the snapshot and pass it over to Solpar PM.

If SOLPAR engineer can’t drive around in the clockwise or anticlockwise direction then he has to mention the reason against the same along with a snapshot proof. Also if for the stationary test, SOLPAR engineer is unable to go into the main lobe while still in car, then he must try to walk and go into major lobe of the sector, if even that is not possible then he should take snaps to support the same.

The SOLPAR engineer should not wait more than 30 mins (post escalation to LSMR and self troubleshooting) for any issue resolution at the site. If issue resolution is taking time, then he should move to the next site.

Post SCFT Drive

All snapshots post SCFT (road and antenna obstructions) should be taken and sent to SOLPAR Project Manager/ Samsung Area Manager/Circle RF Lead.

Backup of log files in memory card to be taken by the DT (this will required if any file got corrupted during upload). Same to be handed over to Circle RF Lead.

Contact LSMR Engineer to lock the site (all three sectors).

Handover the keys back to from where they were taken.

Inform the Solpar PM and Samsung RF lead about completion of the drive test.

Move over to the next site.

This will automatically upload the logs after every test scenario.

Instead of pressing Ok if you choose to cancel or mistakenly press cancel then you need to upload logs manually as explain next slide

New features added…..log Upload - Manual

Uploading of logs can be two ways : Manual

If you missed or choose to not to upload logs auto when

there was a prompt every time then upload manually

Press “Log Upload” button and it will show list of logs

pending to be uploaded

Select the logs to be uploaded based on date &timestamp

Upon uploading the logs the file names will disappear

from pending list

NOTE : Cycle is very important in order to distinguish logs

Unless mentioned by RF Optimizer or RF lead never change

cycle number. It should be always “1” for all the log files /

test scenarios for one round on any given day. Only when

you are requested to do second round another or other day

you will be asked to change cycle number to “2” by your

RF optimizer otherwise don’t change

New features added…..log Upload - Automatic

Uploading of logs can be two ways : Manual or Automatic.

NOTE : The size must be set to

50MB (Mandatory), Latest XCAL

ver. will automatically start new

files after 50MB.

If you don’t set it right, there will

be re-test request as logs of

improper size will cause pre-

processing issues

New features added..FTP server selection

Manual selection of FTP server possible..

New features added…..VOLTE dialed call

SCFT -S4 Mini - troubleshooting Guide

No Network service on Handset

1) No network service on S4-Mini handset

Observed Issue:

As shown in picture below though we are able to see our network parameters

being received by the S4-Mini handset, the handset is not registering to the LTE

network.

No Network service on Handset…

1) No network service on S4-Mini handset

Root Cause:

As shown in picture below the “Mobile data” or “Data roaming” settings was

unchecked under “Mobile networks” settings.

No VoLTE service status on S4-Mini handset

2) No VoLTE service status on S4-Mini handset

Observed Issue:

As shown in picture below, though we are able to see data services are active, no

VoLTE service is being observed. The internet & FTP session are running fine as

shown. When VoLTE call is made it shows “mobile network not available”.

No VoLTE service status on S4-Mini handset…

2) No VoLTE service status on S4-Mini handset

Root Cause:

As shown in picture below, problem was caused due to change in “PDN

preference settings”. Here “Enable Internet PDN” was unchecked. Please

restart the phone after checking the “Enable Internet PDN”.

Any change to the VoLTE configuration apart from above element, can cause

this type of problem.

XCAL-Mobile Software (Not XCAL-Auto Call) doesn’t start

3) XCAL-Mobile Software (Not XCAL-Auto Call) doesn’t start

4) FTP DTUL failed on Handset

Root Cause:

As shown below, the FTP URL in which file is going to be uploaded, does not

change as per FMS server settings. This caused FTP traffic failure on the slave

handset.

This issue could be due to XCAL-Auto Mobile Version mismatch or old version

being used on slave handset as shown, since after upgrading the XCAL

version, the issue got resolved.

Not able to download scenario

Unable to download Stationary or Moving scenario

check the FTP server connectivity in your phones, check the IP address, user id and password and server path as shown below.

Important Notes

Sector Swap Verification

After Physical site parameter verification, conduct drive test in clock wise and anti-clock wise direction to identify any sector swap

If found, take corrective action before going for coverage drive test

If service-direction of PCID has changed, Data Throughput degradation and Handover Fail can be observed

Sector Swap / Call drop: During Stationary test , Engineer must verify correct PCI for every sector, This can be done by checking the Changed PCI per sector and matching it will DTR or Cell Ref file provided to him by RF Lead.

During clockwise and anticlockwise moving test if there is call drop &PCI is changed after call drop then redo the clockwise/anticlockwise loop if call drop occurs again. Don’t proceed with SCFT & report to RF Lead

SCFT Parameter Requirements

Min Average Max

DL Throughput 2 Mbps 20 Mbps 40 Mbps

UL Throughput 256 Kbps -- 4 Mbps

RSRP -108 dBm -- --

SINR 20 dB -- --

Legend

Throughputs for Moving in Worst condition shouldn’t go below min. as per following table when RSRP = -108dbm and SINR = 20db Please note Throughput should be better when RSRP and SINR is better * Above table is just for reference for worst condition only

Summary

eNB physical check involves checking azimuth (note free range), tilt, antenna height, tower height

SCFT consists of stationary and moving tests

Stationary tests include ping, UL & DL throughput and VoLTE connectivity check

Drive around the site clockwise & anti-clockwise for moving tests

Especially check for sector swap using PCI

Ensure RSRP, throughput and SINR ranges are met

Quiz

Average DL throughput should be at least ____

• 4 Mbps

• 20 Mbps

• 40 Mbps

Sector swap can be identified based on

• PCI

• RSRP

• VSWR

Moving test in SCFT does not include

• FTP

• Either

Work Flow Management for SCFT

Introduction to Work Order Assignment Management

Work Order Assignment Management is also known as WAS.

WAS is going to help users in automating the Work Order(WO) flow in a systematic manner using a portal called SITEFORGE.

Using this portal each level of Management employees will receive and execute their WO or Task assigned to them.

Helps to trace the network status through online mode.

Provides Visual steps to guide users on progress and upcoming steps.

Improves productivity & complete visibility.

Helps users to monitor Parameter Compliance Index(Planned Vs. Actual).

Helps users to Search/Filter Sites & WO based on various parameters.

Some basic changes

1. SCFT together with the 11B, upload later (after 11B), this ensures

1. The eNB is working fine that day

2. No shut down, throughput, VoLTE or alarm issue

2. Local FTP server to be used

3. Mumbai FTP server daily monitoring & cleansing

Cellref reconciliation process (PA1)

1. PCI mismatch 2. Site Location mismatch 3. ECGI mismatch

PA1 (Cellref reconciliation)

At the time of Integration (Commissioning) 1. The LSMR Engineer fetches the dump of above parameter and forwards the logs to cellref team 2. The Cellref team corrects the data in case of mismatch

Azimuth reconciliation process (PA2)

1. ATP 11A Data is considered final, Cellref & BSP to be aligned to 11A (already in progress) 2. Sites have different Azimuth in actual 3. The sector drive test does not match with cellref BSP

PA2 (Azimuth Correction at Site) – PA2-1: Where Integration is done (To be verified & corrected by SCFT Team) PA2-2: Where 11A is done, but Integration is pending (To verified & corrected by Integration Team) PA2-3: Where 11A is not done, QC2 is pending (To verified during QC2 & get corrected before 11A) PA2-4: Where change of Antenna parameters not possible site, change cellref with RJIL in loop.

At the time of SCFT, the SOLPAR team will be given a print of cellref data, containing the following:1. Azimuths 2. PCI 3. Site Lat/Long The SCFT SOLPAR Team to 1. Check the actual Azimuth, and adjust antenna to match cellref, if required. 2. Check the PCI & Site Lat/Long. 3. Record the above data and Carry out the SCFT Test. 4. SOLPAR to be penalized if Azimuth not corrected before SCFT test.

PA2-1: Where Integration is done (To be verified & corrected by SCFT Team)

Hand Over test process (PA3)

1. The HO failure is high

PA3 (HO testing process)

The SCFT SOLPAR Team to 1. Make at least two rounds in each direction (clockwise & anti clockwise).

Modification in SCFT test automation tool 1. A separate test scenario on X-CAL

Ensure sufficient Coverage Samples (PA4)

1. The coverage samples and drive routes should be ensured.

PA4 (Drive Route process)

The Drive Route Should be decided on Google Map within BSP boundaries 1. The BSP to be provided to circle RF Leads 2. It should be possible to super-impose the BSP boundaries over Google map 3. The SOLPAR co-ordinator to take print of Google map with BSP boundaries,

indicate the route on the map and provide to drive test team. 4. Drive test team to follow the map, sign-off & submit.

File upload process (PA5)

1. There is a large NO/PARTIAL REPORT issue due to incomplete upload of files.

PA5 (File Upload Process)

1. The FMS should generate an SMS for the completion of all files 2. The X-CAL should have RED/GREEN indication for upload of mandatory files

Sector Swap Confirmation process (PA6)

1. There are sites where the CPRI cable is swapped with other sector RRH.

PA6 (Sector Swap Confirmation Process)

1. The CPRI swap test will be performed during 11B.

Throughput Confirmation process (PA7)

1. There are sites the throughput observed during SCFT test is too low.

PA7 (Throughput confirmation)

1. Since the KPI is for info only, RJIL should not hold the SCFT. 2. The SOLPAR team should contact circle RF lead if the throughput is lower than

xxMbps, and should not proceed with the SCFT drive.

Stationary Test process (PA8)

1. The Attach & VoLTE KPI failure is high.

PA8 (Stationary Test)

1. There will be two attempts for Attach testing in the X-CAL itself, rather than one. 2. QC1 radio bearer should be mandatory for VoLTE call. 3. If the VoLTE is not successful, the SOLPAR should contact circle RF lead, and

should proceed for Drive Tests.
