Transferring the snapshot into the local site

When command manager shows the successful export complete status connect to file Zilla to copy the exported file into the local computer using the path

“ /opt/nortel/data/cmCML”

Create snapshot for specific sites/RNC’s

Click on File and select network layout.Of the avaialble networks select UTRAN and say ViewList of all the RNC’s in the UTRAN network are displayed in the Navigator window. Select the specific RNC whose snapshot is to be created and double click on it to display Resource browserResource browser has all the NodeB’s in that specific RNC along with the RNC displayed as iconsRight click on the RNC icon and and select configuration, cmXML, Export NE Do a similar selection on any other RNC’s that are to be added along with the current.

Create snapshot for specific sites/RNC’s

CMXML Export window is displayed showing only the specific selected RNC’s

Select all the RNC’s that needed for the snapshot and select “ compressed”, “ provisioning” and “customer” options

Name the snapshot that is to be exported and click on “ export now”

Importing snapshot into wipsWms exports the snapshot in .xcm format

How to Import the snapshot in Wips :

Click file and select “import and export”Select “import snapshot”and click on nextSelect “ replace initial snapshot and discard existing workorders” and click next

Importing snapshotBrowse to select the specific .xcm snapshot that was exported from wms

Select edit filter options in order to import only specific parameters

Importing SnapshotSelect the specific RNC’s that are worked on as shown

Importing snapshot

All the selected RNCs are loaded into wips for reference. FDDcell, UMTS neighborcells, GSM neighbors, UMTS remoteFDDs, RNC etc tables Can be exported into the computer in .html formats from here.

WO Creation Create the input with all required columns defined in an excel spreadsheet

Select all the data in the sheet to be executed and copy it to the clipboard

WO Creation Before creating the work order, make sure to import the snapshot ,into wips ,of all the RNC’s involved Select the specific location for which the work order is to be createdThis Case is for UMTS NL, so umts neighboringcell is selected. Select Edition tab and display it by type. Right click on any of the cell in the current selection and click on “ create/update instances using clipboard” Go to work orders tab to see a new work order being created. Network changes that are going to be made and their number will be shown . Select the current work order and name it and click apply

WO ExecutionRight click on the newly named work order and export it to the local file system for execution as shownSelect a name for the output file and saveA duo of the current work order and its reverse will be saved in the chosen location as .xwo file

WO Execution

The exported work order is to be transferred on to the server at the cmXML location.

Connect to filezilla again and transfer the work order duo to the server at the same location

“ /opt/nortel/data/cmCML”

Sessions managerExecuting the work order in wms:Click on configuration and select “sessions manager”In the sessions manager window select “ create new session”Name the session for easy identificationSelect the work order that was transferred and is ready for executionSelect next

Sessions managerOnce the work order is imported into wms, creation parameters window will be openThis shows the actions to be performed following the current work orderOnce the analysis is completed click launchCreation for the new session with status update and summary window appears

Sessions managerMake sure the summary tab shows validate result “ error free”Any errors in the work order creation will be shown at this stage as a red cross mark in the validate result columnFinal Step is to activate the session for launching the changes into the network.Click on activation and click launchCheck the status and once its complete do not forget to release the session

Alarm printSelect the network layout and the specific RNC where the site belongs toDouble click on the RNC for the Resource browser to be displayedRight click on the site which shows the alarm to know the alarm details on that specific siteRight click on the RNC and select show alarms to see all the alarms in that specific RNCAlarm manager window that is displayed shows the alarms related to all the node B’s Select a specific alarm to see the details like its code, specific problem, components, location of the node B, severity of the alarm etc

Parameter changes

Hardware configuration checksLocking and unlocking the site/FDD cell

Open resource browser in wms and go to the specific node B that is to be locked or unlocked.Talk about selecting fdd cell after adding another snapshot

Right click on the nobe B and select configuration. Go to “set administrative state” option for the “set administrative state action window” to be opened. Select the displayed node B or the FDD cell which needs to be locked/or unlocked and click on the respective button at the bottom

Hardware configuration checksEquipment monitor ( RNC) : Right click on the nobe B or the RNC icon in the Resource browser and select Equipment MonitorRNC’s Equipment montor window can be seen below. It gives details like the current RNC software version, Cluster ID, iub attach port number, RNC ID, complete general as well as dynamic data

Hardware configuration checksEquipment monitor ( NodeB) :

Right click on the nodeB instead of the RNC in the resource browser for displaying the one BTS Equipment for that specific NodeB.

Click on the node B to check its corresponding FDD cells

General details for the nodeB are displayed like the frame size, controlling radio information, Latitude and longitude, power utilization, number of sectors, expected and detected Tx amplifier model number, slot number, inventory type , NodeB ip address and subnet mask etc

Hardware configuration checksObject editor: Right click on RNC/ Node B in the resource browser and select Object Editor for the windowSelect the specific FDD cell which is to be edited Look for the attributes that are displayed and select for editingWe can display those attributes that were recently changed or simply display everythingAttributes like cellId, OCNSload status, can be changed or reset in the details tab as shownAt all times, we need to be alert as any change made to it would affect the live node B that is currently on air and is taking traffic

Hardware configuration checksRadiosSelect FDD cell and click on radio/ 1Each FDD cell has a radio number , which starts with 1 usually and are assigned in ascending order as we add sectors / carriers on the node BCheck the radio details displayed in the bottom of the screen as we click on the specific radio

Hardware configuration checksRadiosRight click on each of the radio to diagnose if there are any issues or check the complete configuration in the object editor or lock and unlock the FDD cell corresponding to that radio or even to RESET the radio

pmv commands for KPI’s

Open PuTTY connection managerSelect the RNC to which your site belongs Log in using the username and passwordSee screenshot to know how the output looks like

pmvGive the command : “/home/Support/monitor/pmv/pmv6”The list of RNC’s under the connected group are displayed.You will be prompted to enter the line number or the RNC Enter the number of your RNC in the list displayed aboveInformation about the version of the RNC and the location from where the RNC is being read is displayedEnter the command ds 6This will start reading the RNC and will show us the intervals in which it is reading the values

pmvEnter the final command that will extract the KPIs from the selected node B“ tr nodeb SITENAME kpi 11c 13c 14c 16c 33c 35c”This will display the KPI values of the site that we requested for ( in this example site name was MOU1056)
