5. COMMISSIONING the 3G Flexi WCDMA Multiradio BTS

NOTE: During this setup, the 3G Flexi WCDMA Multiradio BTS must be the Master, in that case it should be commissioned first before commissioning the 2G Flexi Edge Multiradio BTS.

5.1 Define the laptop IP address as shown in the figure below. This will allow you to interrogate locally the 3G Flexi Multiradio equipment.

A 10base-T Ethernet cable with RJ-45 connector is used for connection to the system module (FSMD/E) LAN port.

Laptop OS should be Windows XP Home/Pro, Vista and Windows 7 (for Windows 7 & Vista, open the BTS site manager as administrator for it to work).

Nokia Flexi BTS Site Manager (BTSSiteEM-WN70-7.1.1077) should be installed in your laptop.

3G Datafill file is needed for the BTS parameters.

Concurrent mode/RF sharing licenses (Ru30) MUST be already installed on the BTS by the ROC/NOC before starting.




of 60 Date: 06/27/2012

Title


Sec4.2 of this document MUST be satisfied.

Perform back up of the existing configuration of the Flexi BTS for fall back procedure if needed.

6. Launch the BTS Site Manager

Before starting, make sure that the preparations have been made as highlighted in sec5. The following steps will guide you interrogating the BTS equipment.

1. Start the Nokia BTS Site Manager by clicking the icon on your desktop. The task selection view opens as shown below.

2. If you want to establish a local connection, select the Local option from the IP adress list.

3. If you want to establish a remote connection, define the IP address of the remote BTS.

4. Enter the Username and Password. The default username is Nemuadmin and the password is nemuuser.

5. Click connect.




of 60 Date: 06/27/2012

Title


If multiple versions of BTS Site manager are installed on the PC, the appropriate BTS Site Manager version is selected automatically.

NOTE: If there is a Failure to connect to BTS, possible cause below

- Software not compatible with new FTLB transmission Module.- Swap FTLB with FTIB and reconnect, update software as indicated

below.- When software is successfully uploaded, replace FTIB with FTLB

and reload software to continue with commissioning.

6.1 Updating the BTS Site software

Updating the BTS software is optional. You should do it only if the BTS does not have the required software version. Follow the steps below.

1. If there is mismatch in the software, a dialog box opens as shown below. Otherwise you have to go to the update SW to BTS site menu.

2. Select file button to locate the target build of the new SW as shown below and click open.

3. The current target build is TargetBD_WN7.0_1104_1270 04 .zip




of 60 Date: 06/27/2012

Title


4. Select the activate SW after update check the box to enable the activation of the new SW in accordance to SW updating. Click the update button to begin the SW update.

5. Click the close button to close the Update SW to BTS Site dialog box.




of 60 Date: 06/27/2012

Title


6. Check “SW release version: WN7.0 1104 1270 04” is loaded

Note: This exercise will also update the SW versions of the RF Module: FXDA. If any case there is “incompatible SW alarm” just reload the SW.

6.2 Manual Commissioning

Before commissioning is done, click on “Antenna line management and un-tick all “3GPP/AISG communication” boxes as indicated. This has to be done before any 3G Multi-radio commissioning starts. Ensure “Reset after sending” is enabled and send new configuration to BTS. After reset check “Antenna line management settings again to verify “3GPP/AISG communication” boxes is unchecked. Only after this proceed with commissioning

If no commissioning file(.xml) is available, Nokia Flexi Multiradio site should be commissioned manually. The Flexi Multiradio BTS and/or the flexi transport module (TRS) are commissioned with the commissioning wizard in Nokia Flexi BTS Site Manager. The commissioning can be started when the modules are on “initialised” state. Follow the steps below.




of 60 Date: 06/27/2012

Title


The wizard features back, next, cancel and help buttons for navigating. The next button brings up the following page in each commissioning file. It guides you through the commissioning process and prompts you for the required parameters.

1. Click View tab, choose the commissioning button on the view bar or choose the commissioning menu item. The commissioning introduction menu opens as shown below.

2. Choose the BTS site (will commission the BTS and TRS parameters) and choose manual commissioning type.

6.3 Define site properties

Commissioning requires that Name, BTS ID, A2EA and IP addresses are defined.

1. Enter the name of the BTS site in the name field2. Enter the location.3. Enter the description or configuration of the site as per profile in

the plan.4. Define the BTS Id ( for Cell C site name = BTS Id).5. Define the IP address of the: TRS BTS, RNC and NTP server (refer

3. Site parameters, DCN, Connection Configuration and AAL2 user planes have been configured in RNC.

4. Call NOC to download Licence’s and Unlock the Site. See status below.

7. COMMISSIONING the 2G Flexi EDGE MULTIRADIO BTS

NOTE: on the 2G BTS, First thing to be done is to run “Undo Commissioning & remove Traffic Bypass capacity” to ensure all data is cleared from the flash memory.

9.1 Define the laptop IP address as shown in the figure below. This will enable you to interrogate the 2G Flexi Multi Radio BTS equipment.

A 10base-T straight Ethernet LAN cable with rj-45 connector is used for connection to the system module (ESMB/ESMC) LMP port.

2g Flexi BTS Site Manager (EX4.1_MP1.0_2G_BTS_Site_Manager_BL055) should be installed in your laptop with the latest BTS SW release (EX4.1_M1.0_BL058_A51_A53).

Laptop OS should be Windows XP Home/Pro, Vista and Windows 7 (for Windows 7 & Vista, open the BTS site manager as administrator for it to work).

Updated file for BTS parameters e.g. site id, bcf id, configuration, A-BIS plan etc. This should be provided by Network Planning.

3G Commissioning file (XML) previously saved from the 3g commissioning earlier.

Sec4.2 of this document MUST be satisfied.

Perform back up of the existing configuration of the Flexi BTS for fall back procedure if needed.

8. Launch the 2g Flexi BTS Site Manager

Before starting, make sure that the preparations have been made as highlighted in sec4. The following steps will guide you interrogating the BTS equipment.

Start the Nokia 2G Flexi BTS Manager by clicking the icon on your desktop. The task selection view opens as shown below.

10.1 BTS SW Update

The first step of the commissioning is BTS SW Downloading/Update. This is necessary to align the current SW packet of the BTS with the new release BTS SW. It starts with selecting the “BTS SW” and followed by “SW update”

Then, we must browse and select the “header” or “master” file to start the download. The SW version BTSM4113.3A




of 60 Date: 06/27/2012

Title


It is recommended to select the option “Forcé Download” to guarantee the downloading of all files of the new SW. If we don’t mark this option, only the changes in between versions will be downloaded (depending on the versions).

Press the “update SW”. The progress bar will help us to follow the process. Notice that FIREWALL SW running on PC could BLOCK the downloading. When the Download is finished, The BTS will restart and the PC automatically connect to the BTS. Multi Radio BTS doesn’t autodetect un-commissioned radio modules, thats the reason why only the system module appears on the screen.

ON-LINE commissioning is when you are physically connected to the BTS via your straight LAN cable.

Check ‘Force BTS Download All Application Files’




of 60 Date: 06/27/2012

Title


10.2 Perform “Undo Commissioning of BTS”

This will last a few minutes and when finished, the BTS will restart. Notice that any change in the BTS configuration needs a BTS reset to be effective.

This will last a few minutes and when finished, the BTS will restart. Notice that any change in the BTS configuration needs a BTS reset to be effective.

NOTE: 3g Commissioning file(XML) is needed to be downloaded into the 2g Flexi Multiradio BTS.

After restarting, we choose again “commissioning wizard” and then “Commission manually” to bring you to the Site Specific Information.

10.3 Site Specific Information

Note that OPT1 is untick and your synchronization is also untick since your 3G BTS is your master. Note also that the RF module (FXDA) is already defined.

If DCS1800 is being used, then we need to add new RF chain for FXEA using OPT2.

10.6 Local Sector Settings

Since we hav Rx Sharing of FXDA (sector 4,5 & 6), the máximum allowable Carrier power is 60W. Since 3G BTS uses 40W carrier power already, our 2G BTS will now have a máximum of 20W carrier power to be used. It can be 10W depending on the RF plan. While your FXEA (sector 1,2 &3) will still have a máximum 60W carrier power since its not shared.
