Introduction

The following items are checked: • • • • •

the grounding power cabling and supply voltage other cables and fibres LED status during power up TX/RX/antenna connector torque check (not relevant for Flexi Zone Controller)

For more information, refer to hardware product description, installation and cabling documentation. Performing commissioning The Flexi BTS and/or Flexi Transport sub-module (TRS) are commissioned with the Commissioning wizard in BTS Site Manager. Commissioning can be started when the modules are in 'Initialised' state. The wizard features Back, Next, Cancel and Help buttons for navigating. The Next button confirms the entered parameters and brings up the following page in each commissioning line. The Back button reverses to the previous page in the wizard. The Cancel button cancels all the entered parameters and closes the wizard. The Help button displays help topic. All fields marked with a red star are mandatory and need to filled in order to proceed to next step. For more detailed information on various commissioning parameters and options, see context sensitive help topic for each page, by either pressing F1 key or using the help icon. All parameter changes are sent to the BTS site after going through all the available commissioning steps, in the Send Parameters step and the site reset is done (if required), only then changes are reflected. Commissioning parameters can be saved in an XML file for future reference. To know more about certain features, see LTE , Feature Descriptions and Instructions or WCDMA , Feature Descriptions and Instructions. To know more about different configuration types, see Flexi Multiradio BTS WCDMA Supported Configurations Excel in NOLS or LTE Base Stations Supported Configurations Excel. To utilize the full capacity and all of features of the WCDMA BTS, required licenses need to be downloaded to the BTS from Nokia NetAct™. For more information on licenses, see the WCDMA RAN License Operation document. Autoconnection enabled This step is automatic if the autoconnection feature is enabled. If autoconnection is not enabled, the connection to the BTS must be done locally. This feature enables automatic connection to servers in the network, and an automatic establishment of the O&M connection of the BTS to the O&M system. Only HW and cabling need to be installed at the site. There is no need for an experienced telecom personnel to be at the site during the commissioning of the BTS, as the integration of a newly installed BTS is fully automated. When the BTS is powered up, it will automatically check the BTS commissioning status, establish IP connectivity, and retrieve operator certificate and trust anchors (optional). As soon as the final certificates are available, the BTS starts the secure O&M plane connection to the NetAct framework.

Introduction


For a detailed description of the autoconnection feature, see the SON Management document. Autoconfiguration enabled This step is automatic if autoconfiguration is enabled. If autoconfiguration is not enabled, the BTS can be configured remotely using O&M connection, established by the autoconnection feature or locally. The BTS autoconfiguration feature provides automatic commissioning and configuration of new or re-homed base stations from a remote network operation center with minimal manual intervention. The automated configuration is initiated by the eNB auto configuration agent and controlled by the NetAct auto configuration application, which belongs to the overall NetAct SON coordinator application. For a detailed description of the autoconfiguration feature, see the SON Management document. SW update This step contains all the actions required to update and/or download SW to the equipment or to the PC for on-site equipment management. When autoconnection and autoconfiguration are enabled, software updates are fully automated. When disabled, software must be updated locally (autoconnection disabled) or remotely (autoconfiguration disabled). Commissioning file download from NetAct This step is automatic if autoconnection and autoconfiguration features are enabled. NetAct downloads the configuration file to the BTS and activates it. On activation, the site is reset. Commissioning tests This contains the key tests that need to be carried out to ensure the basic functionality of the equipment in question. Some of the tests are activated automatically, some of them are run as a part of the Commissioning wizard and some might need to be activated separately. Some of the tests are optional and are run for diagnostic purposes if there is a reason to suspect the functionality. Typical tests and measurements for WCDMA BTS: • • •

external alarm and control tests site support system alarms shown at the BTS RF max power measurement (optional test)

Typical tests and measurements for LTE BTS: • • •

external alarm and control tests internal loop tests site tests

Some of the functional tests need more parameters than are available during commissioning and thus can be run only after the network element has been integrated and can retrieve the remaining parameters from the RNC. See BTS Site Manager Help for more information. Integration (relevant only for LTE releases)

Introduction

With the configuration end phase, the BTS starts establishing S1 connection with the configured MME. If IPsec is activated, then the appropriate IPSec Tunnel (or tunnels) created before the SCTP associations - are established. In case of completely preconfigured neighbor site configurations, the relevant X2 SCTP connections are setup as well. Parameter setup In case autoconnection and autoconfiguration are not enabled, the parameters have to be entered locally or remotely after entering basic parameters for O&M connection. This can be done in three ways (SW update may be necessary before the parameter setup): • • •

Using a planned commissioning file where all parameters are predefined. Using a template commissioning file where the site-specific parameters need to be entered manually. By entering all the parameters manually.

This contains all the actions required to set up the parameters for commissioning and for integration. Parameters might include software parameters fed in manually or as a file. The equipment specific product documentation describes the details. The site will be reset after all the required parameters have been entered using one of the above mentioned methods.

g

Note: When a parameter is not mentioned in a commissioning instruction, the parameter should be left at its default value even though it is possible to change it. Troubleshooting The purpose of troubleshooting is to rectify the problems found by analyzing the test results and perhaps running some further tests to identify the cause of the problem. Information about troubleshooting hints and optional tests can be found in the equipment specific documentation. To avoid repetition, it is essential to be aware of the current known problems. The Technical Notes (TN), List of Generic Faults and Change Deliveries (CD) need to be studied from time to time for latest information about known problems and work-around solutions. Based on the experience and HW repair statistics about the cause of the faults one major group is 'no fault found'. To minimize unnecessary shipping, spare waiting and 'no fault found' reports, it is essential to double-check the suspected module one more time before sending it for repairs. Once the module is suspected and the replacement seems to rectify the problem, the original suspected module needs to be tried once more. In many cases the actual reason which rectified the problem is power off/on-reset or plug off/push in reset. When the module is suspected or proven faulty, the appropriate error report attached with possible log or test report files is filled. The following information needs to be clearly available in the report: • • • • • • •

In case of module replacement the site inventory needs to be updated. Reporting The most important part of commissioning is reporting. Without relevant reports the equipment can be considered uncommissioned. The purpose of reporting is to keep track of the latest status of the equipment and the work done. Some new equipment supports features where the reports are automatically updated to the main database in the NetAct™ system, some need a few manual steps, and some reports need to be saved/printed manually. Typical reports are: • • • • • • • • •

commissioning report produced by the Commissioning wizard of BTS Site Manager autoconfiguration report snapshot file saved by BTS Site Manager site inventory report delivery reclamation for missing items failure report for each faulty module failure report for each new problem site deficiency report for outstanding problems site progress report

Some of the reports can be used as a technical appendix for site acceptance documents.

Updating BTS Site Software

4 Updating BTS Site Software Procedure on how to update BTS Site SW. Purpose System release upgrade should always be done in a top down approach, that is: 1. NetAct upgrade 2. OMS upgrade 3. BTS upgrade For more information, see LTE System Upgrade or WCDMA System Upgrade depending on the technology in use. The software for the transmission sub-module, Radio Modules and Radio Heads is included in the software package for the BTS site and cannot be upgraded separately. Software upgrades can either be performed manually for each BTS using BTS Site Manager, or automatically via the Network Management System (NetAct). Updating the BTS site software is optional and should only be done if the BTS does not have the required software version. In the Update SW to BTS Site dialog box the BTS Site Software can be updated. This procedure does not download application files that already exist in the Flexi WCDMA BTS or Flexi Transport sub-module that have the same version information. You can view the current SW versions in the Site Information dialog box by choosing the Software → SW Versions menu item.

g g g

Note: If the BTS site is connected to Nokia NetAct™, NetAct manages the BTS site SW (that is, checks the SW version and, if it is different than the SW in the NetAct database, downloads new SW in the BTS site). Note: In case of SW fallback or SW rollback from WBTS16 to WN9.1, the passive software version may be displayed incorrectly. Note: FSMF is delivered with Factory Delivered SW (FDSW). Site Manager does not detect any RFMs/RRHs and ALDs until the System Module is updated with appropriate technology SW. For details, see the Technical Support Note: TS-SRAN-HW-0108.

Procedure 1

Launch BTS Site Manager.

2

Choose the Software → Update SW to BTS Site menu item. The Update SW to BTS Site dialog box opens.

Click the Select File button to locate the master file containing the new software. The Select Build Descriptor dialog box opens. Locate and select the master file (TargetBD.xml or SW package zip file), and click the Open button. If the zip file is selected on clicking Open, the files are decompressed. The new SW version is displayed in the Update SW to BTS Site dialog box.

4

Select the Activate SW After Update check box to enable the activation of the new software in accordance with SW updating. Note that if you do not want to activate the new software at the same time when downloading it, you can leave the option unchecked. This causes the SW to be downloaded to the BTS site without implementing it. . To activate the SW later with the Activate SW After Update option selected, you have to perform the SW update again.

5

Click the Update button. The Update button is enabled if a valid master file has been selected. SW download takes about 20 minutes. The time depends on the number of items to be downloaded and the bandwidth of the DCN connection, for example. The Update Progress steps show the transfer status. Wait for the SW update to be completed. If the Activate SW After Update check box was selected, the SW is activated and the site will be reset. To stop the SW update, click the Stop button. If the SW download fails, update the software again.

5 Commissioning overview Purpose Below is an overview of the BTS site commissioning. There are four different commissioning types: 1. Template Commissioning Template commissioning provides an option to commission network elements using a predefined template file. Since the same configurations are commonly used in several network elements, a commissioning file can be stored and used as a template file when commissioning elements for example with a similar hardware configuration. This will significantly reduce the number of parameters that need to be configured as generally only site specific parameters need to be changed - BTS name, id and IP address, for example. Site specific parameters are configured on the Site Properties and BTS properties commissioning pages. 2. Planned Commissioning Planned commissioning provides an option to commission network elements by loading a commissioning file, specifically made for the BTS site onto the Flexi BTS and/or Flexi Transport sub-module . The commissioning file can be prepared with the Plan Editor tool in NetAct Radio Access Configurator. The file is downloaded to the PC by means of the NetAct Radio Access Configurator - Site Configuration Tool. For more information on the procedures in plan-based commissioning with Radio Access Configurator, see the Rolling out the WCDMA RAN document in the Nokia NetAct Radio Access Configurator product documentation (relevant only for WCDMA releases). You can also create the commissioning file with BTS Site Manager. For more information on the file creation, see the BTS Site Manager Online Help. 3. Manual Commissioning If no commissioning file is available, Flexi BTS site requires manual commissioning. 4. Reconfiguration Commissioning Reconfiguration commissioning provides an option to commission already commissioned network elements. The reconfiguration can be used when a new configuration can solve problems or when a new configuration can release HW resources for another site and/or make an element to function more efficiently. During the reconfiguration, the site remains operational up until the mandatory site reset in completion of the commissioning. All parameters needed to configure the BTS site are determined at the network planning stage. It is essential that the input values match the expected values in the network plan. For more information on commissioning parameters, see the Flexi Multiradio BTS LTE Commissioning, RNW and Transmission Parameters or Flexi Multiradio BTS WCDMA Parameters Excel depending on the technology used.
