Note

Note

Note

BTS TX antennas and radio link antennas are considerable radiationsources. Avoid standing close to a radiating antenna or any of its elementswhen measuring the location coordinates and altitude.

The site survey data includes the BTS TX antenna coordinates for all BTSsectors. If the data has been imported to Nokia NetAct, the correctcoordinate for the serving BTS sector is proposed in the Nokia LMU WorkOrder file. If the preliminary site survey has not been completed and theBTS sectors are no more than 2 metres (6.6 ft.) apart, the mean coordinatesbetween BTS sectors can be used.

2. Check that the default Reference BTS TX antenna’s Altitude data complieswith the altitude measured with the hand-held GPS receiver. Correct thealtitude if necessary.

Use the WGS-84 map datum in the hand-held GPS receiver when measuring thelocation coordinates and altitude.

If the default Latitude, Longitude and Altitude data deviates from the measuredlocation and altitude, record the deviation to the User Information dialog boxwhich appears on the window when the Commissioning Wizard is finished.

The location coordinates for the BTS antennas must be entered correctly, becausethey are used for delay compensation calculations. Entering the locationcoordinates is especially important when internal GSM antennas are used.



Commissioning

Note

To enter the location data for the neighbouring BTS sector antennas:

Figure 12. Setting the LMU GSM antenna delay in external GSM antenna mode

a. If internal GSM antennas are used, click the respective tick-box andproceed to step c. If external GSM antennas are used, proceeddirectly to step b.

b. In external GSM antenna mode, check the Velocity factor for AirDelay, LMU GSM Feeder Delay and LMU GSM Jumper Delay. Thedefault velocity factor is 1.00 for Air Delay, 0.90 for LMU GSMFeeder Delay and 0.70 for LMU GSM Jumper Delay. Correct thedata if necessary.

The default Air Delay for the reference LMU GSM antenna is zero.If the BTS mast is very high and the handset is located close to themast, the altitude difference between the LMU GSM antenna and thehandset may cause an error in the location measurement of thathandset. If necessary, the error may be minimised by entering anegative Air Delay value for compensation.

Enter the lengths of the LMU GSM feeder cable and the LMU GSMjumper cable in metres/feet to the respective fields. Correspondingdelay values in nanoseconds (ns) are shown automatically when thecable lengths are entered.


Commissioning

Note

When the lengths for both LMU GSM feeder and LMU GSMjumper cables have been entered, the Total Delay in nanoseconds(ns) is calculated automatically.

You must select external GSM antenna when existing BTS RX antennas areshared for LMU GSM input. In this case, the lengths of the GSM feeder and GSMjumper cables must represent the mean length of the corresponding BTS RXcables.

Figure 13. Setting the LMU GSM antenna delay in internal GSM antenna mode

c. In internal GSM antenna mode, check the Velocity factor for AirDelay, BTS Feeder Delay and BTS Jumper Delay. The defaultvelocity factor is 1.00 for Air Delay, 0.90 for BTS Feeder Delay and0.70 for BTS Jumper Delay. Correct the data if necessary.

Air Delay is shown automatically in the respective field. It iscalculated from the distance between the LMU GSM antenna andthe reference BTS TX antenna. If the location coordinates of theLMU GSM antenna and the reference BTS TX antenna are the same,Air Delay is zero. If the BTS mast is very high and the handset islocated close to the mast, the altitude difference between the handsetand the BTS TX antennas may cause an error in the locationmeasurement of that handset. If necessary, the error may beminimised by entering extra Air Delay for compensation.


Commissioning

Note

Note

Enter the lengths of the BTS feeder, BTS jumper and LMU GSMjumper cables in metres/feet to the respective fields. Correspondingdelay values in nanoseconds (ns) are shown automatically when thecable lengths are entered.

When the lengths of the BTS feeder, BTS jumper and LMU GSMjumper cables have been entered, the Total Delay in nanoseconds(ns) is calculated automatically.

d. Click Set Value. The calculated Total Delay for the external/internalGSM antenna appears in the time calculation parameters window ofthe Commissioning Wizard (see Figure 10).

You can also enter the delay values in nanoseconds in the time calculationparameters window of the Commissioning Wizard (see Figure 10). You canmeasure the delays with the cable and antenna analyzer (most models show theresult in nanoseconds).

3. Set the Frame Clock (BTS/Q1) and External Frame Clock (EXT/Q1)Delays.

If a narrowband combiner (for example, a Remote Tune Combiner - RTCx)is used, set the delays to approximately 500 ns (or refer to the narrowbandcombiner manufacturer’s requirements for more specific values) tocompensate for the delay caused by the combiner.

If a wideband combiner (for example, a Wideband Output Combiner -WOCx ) is used, set the delays to zero.

If long BTS TX antenna cables or additional extension cables are used(exceeding 10 m/32.8 ft.), add the delay values caused by the long cablesto the Frame Clock and External Frame Clock Delays.

Set the Frame Clock and External Frame Clock Delay values to zero withBTSs that do not support BSS synchronisation.

The Frame Clock and External Frame Clock Delay settings are especiallyimportant with EDGE system base stations.

If BSS synchronisation is used with Nokia Intratalk and Nokia CitytalkBTSs, set them into clock slave mode immediately as described in the nextprocedure because there can be only one clock master in the TalkfamilyBTS clock chain.


Commissioning

Note

Caution

If BSS synchronisation is used with Nokia UltraSite GSM/EDGE BTSs,they are set to clock slave mode at a later stage of the commissioning.

Nokia UltraSite GSM/EDGE BTS software ignores the clock input until it isactivated with Nokia BTS Manager.

2. If the Clock Output was disabled in the previous step, the CommissioningWizard proceeds directly to a dialog box illustrated in Figure 19.

To set Nokia Intratalk and Nokia Citytalk BTSs into clock slave mode:

Use an antistatic wrist strap when handling the BTS units.

1. Switch off the power to the BTS.

2. Remove the BCFB unit from the BTS and set the BTS into clock slavemode by removing the BCFB unit’s dip switch (X1805) from the masterposition. If necessary, you can place the dip switch to one of the componentpins to save for further use (see Figure 18).

3. Reinstall the BCFB unit and switch on the power to the BTS.

5. If the Default Neighbour List is not defined in the Work Order file, selectthe wanted signals for monitoring in the GSM Status window by clickingthe right mouse button on top of the window and choosing Show SelectedNeighbours. Modify the data if necessary and click OK.

6. Refresh the GSM Status window by clicking the GSM icon on the toolbar(see Figure 4). The LMU enters scanning mode, and the GSM Statuswindow shows immediately all the received BCCHs. The BSICs are showngradually as they are decoded. When all the BCCHs and BSICs are shown,the LMU enters measuring mode, and the drifting value for each signal isshown (it may take up to 10 minutes before the first drifting values aremeasured). After that the levels and drifting values of all the receivedsignals are continually updated.

7. Check from the GSM Status window that the GSM signal levels areadequate. The GSM signal level is adequate when the signal level bar isgreen.

Nokia LMU SW is designed not to indicate signal levels exceeding -30dBm.

If the closest BTS’s signal level in the GSM Status window exceeds -40dBm, additional isolation for the LMU GSM RX antenna is required (referto Antenna Requirements).

8. Check that the drifting value for each selected BCCH frequency in theGSM Status window does not exceed 3 m/s.

9. If the drifting value for any neighbouring BTS is too high, the clocksettings of that BTS may be incorrect or there may be a BTS-relatedproblem with synchronisation. Inform the site management personnel oryour superior about the problem.

The drifting values for neighbouring BTSs in the GSM Status window should beconsidered relative until reference BTS drifting is shown.

10. Check that the Bit Error Ratio (BER) for each selected BCCH frequency inthe GSM Status window is less than 1% by clicking the right mouse buttonon top of the wanted BCCH row in the BER column, or by clicking theBER icon on the toolbar and selecting the wanted channels.

Note

11. The neighbouring BTS signals that have too high a BER cannot be used formeasurement. The BCCH transmitter may be faulty, or there may beinterference from an adjacent channel, in which case you may have toadjust the position of the LMU GSM RX antenna(s) (refer to AntennaRequirements).

After adjusting the antenna position, you need to refresh the GSM Statuswindow by clicking the GSM icon on the toolbar.

If a signal level is inadequate or the drifting and BER values of a signal are toohigh, refer to Alarm Descriptions and Maintenance for troubleshooting andinform the site management personnel or your superior about the problem.

If you have not selected neighbours for monitoring with the Show SelectedNeighbours command, or if the Default Neighbour List is not defined in theWork Order file, the LMU enters free scanning mode when you click the GSMStatus icon on the toolbar. In free scanning mode, the GSM Status window showsany signals received by the LMU (max. 16) in order of signal level amplitude.

12. Save the Commissioning Report (the same file you saved after resetting theLMU) by choosing the Commissioning Report... command on the Runmenu to add the updated GSM signal data to the Commissioning Report(for more information on the Commissioning Report, refer to Chapter 5).

You must always save the Commissioning Report before exiting the LMUManager, disconnecting the commissioning PC or leaving the site.

13. Check the data in the Commissioning Report.

14. Disconnect the Manager session by choosing the Disconnect command onthe Run menu.

15. Exit Nokia LMU Manager by choosing the Exit command on the Filemenu.

To configure Nokia Indoor LMU at the BSC:

The BSC commands presented here are used to set up single LMUs, and,therefore, are not applicable to large scale roll-out implementations, which areplanned and downloaded with Nokia NetAct. For more information, refer torespective NetAct User Manuals.

Figure 23. Example of a BSC command as seen at the BSC (ZQWL response)

1. Configure the BTS-specific Q1 settings applicable for Nokia Indoor LMU.

For more information on configuring the Q1 settings, refer to the respective BTSUser Manuals. In the case of Nokia UltraSite GSM/EDGE BTSs, refer to the Q1management section in the online Help of Nokia UltraSite BTS Hub ManagerC2.0.


Commissioning

2. Call the BSC assistant or take a remote connection to BSC to check theLMU state with a ZQWL command. If the Q1 functions properly, thefollowing data should be visible at the BSC (see Figure 23):

• BCF number

• Type: TRE

• Index: Next available transmission equipment number/18 (2 gen.)

• Q1 address: 131 (default)/25 (2 gen.)

• Equipment type: LMUHW

• Equipment generation: Q1E (default)/TMS (2 gen.)

• State: -

3. If the automated Q1 equipment search takes too long, add Nokia IndoorLMU to the BSC transmission equipment list with a ZQWA command.

4. Start the checksum polling and check the equipment generation and stateat the BSC with a ZQUF command.

5. Create the LCS elements for the neighbouring and reference BTSs at theBSC with a ZEXC command.

6. If location and/or BSS synchronisation for the area is activatedimmediately, create the LMU area at the BSC with a ZEXA command toactivate LMU RIT measurement reporting between Nokia Indoor LMUand the BSC location calculation module (SMLC).

LMU usage for the LMU area is set according to the following alternatives:

• 1 for synchronisation

• 2 for location service

• 3 for synchronisation and location service

7. If BSS synchronisation is used and you do not have two serial ports in youCommissioning PC, disconnect the RS232 serial cable from the LMUmodule’s COM/LMP port.

Connect the RS232 serial cable to the MMI connector on the BCFB unit inNokia Intratalk and Nokia Citytalk BTSs (see A of Figure 24) and on theBase Operations and Interfaces (BOIx) unit in Nokia UltraSiteGSM/EDGE BTSs (see B of Figure 24).

8. If BSS synchronisation is used with Nokia Ultrasite GSM/EDGE BTSs, setthem into clock slave mode with Nokia BTS Manager.

You may activate synchronisation with BSS 10 by entering the LMU area dataaccordingly. For full support, BSS 11 is required.

If the BTS has been set to clock slave mode with Nokia BTS Manager, BSSsynchronisation of Nokia UltraSite GSM/EDGE BTSs can also be activatedremotely afterwards by changing the LMU usage setting for the LMU area witha ZEXB command. The command initiates the BSC to send a Frame NumberOffset to Nokia Indoor LMU to activate the clocks.

Changing the default clock out timing settings for the GPS fix

The default clock out timing settings for the GPS fix should only be changed forBSS synchronisation purposes if necessary. They are not changed as part of thenormal commissioning procedure.

To change the default clock out timing settings for the GPS fix:

1. Click the Advanced option on theView menu to activate the advanced usersettings on the Maintenance menu.

2. Select the Clock Out Timing Settings option on the Maintenance menu.

5. To activate the changed time settings, choose the Reset LMU command onthe Maintenance menu and click Yes to reset the LMU module.

You must always reset the LMU module after you have changed thecommissioning parameters to activate the new settings.


Commissioning report

5 Commissioning reportAt the end of the commissioning procedure, the Commissioning Report is savedin a file on the PC hard disk. The report is an XML file that you can open withNokia LMU Manager SW or with an XML editor such as Microsoft XMLNotepad 1.5 or later (see Figure 26). You can also open the CommissioningReport with Internet Explorer, but the layout of the report will be different thanwith an XML editor.

The Commissioning Report provides the following information:

• Report title

• Date and time

• User name

• User comments

• User actions

• Status

• LMU parameter settings


Commissioning

Note

Note

Note

• LMU installation status info

• LMU GSM status (signal levels, drifting, BER)

The Commissioning Report must be imported locally or remotely to NokiaNetAct Planner where the SMLC object data for the LMU area is modified. Thismodification is important to ensure correct location coordinate information andneighbour list data.

Cable lengths are always shown in metres and the Latitude and Longitude data infull degrees with decimals in the Commissioning Report. If you enter thecommissioning parameters in the BSC database manually, the coordinates mustbe entered in degrees, minutes and seconds.

Only the signals defined in the Nokia LMU Work Order are shown on the DefaultNeighbour List. The Commissioning Report also includes an Off Neighbour Listwhere all other signals received by the LMU are listed for possible future use.

Troubleshooting and fault reporting

Note

6 Troubleshooting and fault reportingIn the case of a failure in the commissioning procedure, check the cause of thefailure from the Commissioning Report. You can also check the LMU alarmsfrom the BTS, BSC, or Nokia NetAct (for more information on the alarms, referto Alarm Descriptions and Maintenance).

The commissioning procedure may fail for the following reasons:

• Cables, connectors, or protectors of Nokia Indoor LMU are faulty.

• The external AC/DC power supply for Nokia Indoor LMU is faulty.

• Cables are improperly or incorrectly connected.

• LMU GPS or LMU GSM RX antenna is faulty.

• LMU module is faulty.

• Network planning is carried out incorrectly or the radio environment isespecially problematic.

• There is a problem in the Q1 bus due to a problem in Nokia Indoor LMU,the BTS, or other equipment.

For more information on fixing possible faults, refer to Alarm Descriptions andMaintenance.

The LMU module should be replaced if the generated alarms cannot be cancelledduring commissioning.
