Service Affecting Alarms

• • • •

Site down High drop Rate Low Tx Power GPS Alarm

• VSWR should be 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 - de cimal format. Update this information into check list for pre-post comparison and for data base 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

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, w hich means that the tilt is 6 degrees {one mark = 2 degree and consider the bott om 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 trac king 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) Stationary Test Procedure:

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( 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.

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 Observed Issue: XCAL-Mobile (Not XCAL-Auto Call) stops after showing message as “License Error (UE time setting must be automatic)”

XCAL-Mobile Software (Not XCAL-Auto Call) doesn’t start… 3) XCAL-Mobile Software (Not XCAL-Auto Call) doesn’t start Root Cause: This was caused since the “Automatic date & time” was unchecked in “date & time” settings.

FTP DTUL failed on Handset 4) FTP DTUL failed on Handset Observed Issue:

FTP DTUL call failed on a particular handset.

FTP DTUL failed on Handset… 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 5) Not able to download Stationary or Moving scenario. Observed Issue:

Unable to download Stationary or Moving scenario Root Cause:

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, condu ct drive test in clock wise and anti-clock wise dir ection 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

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.

If missing neighbor, Add neighbor in each sector Confirm Neighbor List

- Do Handover test before SCFT Drive test. - First take a clockwise drive. Start from Alpha to Beta, Beta to Gamma, Gamma back to Alpha. - Then take a anticlockwise drive. Start from Alpha to Gamma, Gamma to Beta, Beta back to Alpha. • Clockwise : Alpha -> Beta -> Gamma-> Alpha • Anti-Clockwise : Alpha -> Gamma -> Beta -> Alpha - Observe the target PCI change without Call Drop. ※ If the PCI is changed after call drop, then try to HO again. - If call drop happened again and again, then DO NOT EXECUTE SCFT and feedback to Samsung RF Lead immediately.

PA3 Handover Testing Process  How to do HO Test :

[Figure-2. Clockwise / Anti-clockwise Handover Route ]

1. Refer to figure-3, Do Handover test as shown. Start from Alpha sector. Blue route: Clockwise test route. Red route: Anticlockwise test route.

Anti-Clockwise Clockwise

• Clockwise : Alpha -> Beta -> Gamma-> Alpha • Anti-Clockwise : Alpha -> Gamma -> Beta -> Alpha Alpha

2. If HO not happened during test then try it again.

- Go to stationary point in main lobe of antenna and check PCI. - Compare the detected PCI with provided PCI (SCFT DTR) - For swap between sectors, change the CPRI cable of swapped sectors. - Check PCIs before start the SCFT for all three sectors again and if OK then proceed for SCFT Drive Test.

Provide SCFT DTR (Map & Ant. Info) to SOLPAR team

Stationary Test If sector swapped, Change CPRI cable of swapped secoters Report CPRI cable changing status on Site Survey Check List Submit SCFT Site Survey Check List to NOPT engineer

PA6 Sector Swap Confirmation Process  How can check Sector Swap [Figure-4. Stationary Test Point]

1. Choose Stationary Point in the main lobe of antenna.

2. Check that you get only one PCI assigned to test sector. - eg. For figure shown, you must get PCI 9 for alpha sector. If you get 10 PCI then that is sector swap. Alpha

- In this case you have to change CPRI cable to correct the swap. (Alpha PCI 9 CPRI Beta PCI 10 CPRI). 3. Repeat the above procedure for remaining sectors as well.

PA6 Sector Swap Confirmation Process  How to change CPRI Cable 1. The Engineer must carry with him site keys for easy access. 2. Change the CPRI cables at DU to correct the swap. 3. Correct the labeling of CPRI cable after the change. 4. The color code is as shown in picture. • Alpha-Blue. • Beta - Red. • Gamma-Green.

Check Backhaul & Alarm Status. If any issue, Report related team Confirm eNB Health Status

- DL/UL Throughput by Speedtest.net (App.) before test - During drive test if low throughput value is observed, then stop DT and restart the test. - During DT observe the DL/UL throughput changes all the time. - If the low DL or UL T-put is observed during SCFT even though signal condition is good and PCI value is correct then stop the SCFT and make the call again. If issue still persist, contact LMSR engineer.

Raise the issue to Samsung EPC team(DP) in that circle --> RJIL manager in that circle --> IMS team

PA8 Stationary Test  Stationary Test 1. Choose Stationary Point in the main lobe of antenna. 2. Check that you get only one PCI assigned to test sector. - Many field team move from sector to sector for stationary test, but the PCI change don’t happen and they do not notice it. 3. Repeat the above procedure for remaining sectors as well

Summary Work Order Assignment Management is also called as WAS. AM receives SCFT trigger once ATP11B process is completed. AM assigns SCFT Task to Samsung Optimizer & Samsung RF Head. AM distributes(assigns) “Perform SCFT” Task to SOLPAR PM. SOLPAR PM will further assign “Perform SCFT” task to SOLPAR FE(DT Engineer). SOLPAR FE has to accept this task from SOLPAR PM and follow below steps. a)SOLPAR FE will conduct SCFT task using Mobile device(eg:S4 Mini) to complete and upload test data to FMS server(separate process) b)SOLPAR FE will input parameter changes(if any) to siteforge server and submits it for Samsung Optimizer approval. Samsung Optimizer will accept or reject according SCFT test data available in FMS server and flow continues. Overall WAS Improves productivity & complete visibility.

QUIZ Question 1: Who will assign SCFT Task to Samsung RF head ? Ans: Samsung Area Manager Question 2: Who will assign “perform SCFT” task to DT Engineer? Answer: PM(SOLPAR) Question 3: Whether Samsung RF head can reject approved SCFT data by Samsung Optimizer? Answer: A) Yes B) No
