    Welcome

    User Manual 1510.9276.02 - 4.63 13

    Documentation Overview

    The user documentation for the R&S ROMES NPA is divided as follows:The first chapter provides a short tour through the basic functionality and workflow of

    the Network Problem Analyzer. It also lists the changes to the software in the course of

    several versions.

    In the second chapter the basic workflows are described. Here all the functions of the

    User Interface are described in the context in which they are normally used, and their

    interrelation and possible combinations are revealed.

    A reference to all the functionality available in the user interface is given in the third

    chapter. This is more or less a description of functions and dialogs as seen in other

    software user manuals.

    All the analysis modules, the way they can be configured and the meaning of theiroutput results are explained in detail in chapter four. Here one can find most of the

    information needed to interpret and use the analysis results in a meaningful way.

    The final appendix chapter describes some non-use case related issues.

    1.2 Introduction

    The Network Problem Analyzer is an application that is provided to automate the task of findingproblem spots in a radio telecommunication network. It therefore scans the content ofmeasurement files created with the Rohde & Schwarz ROMES software.

    Such files contain data recorded during drive-tests made with mobiles, network scanners andother devices. Each file that is analyzed with the NPA application will be processed usingdifferent units, so called Data Processors or Analysis Modules. These perform various tasks, likeanalyzing Voice Calls, Data Transactions etc.

    Results of the analysis process can be visualized in the NPA application. Different visualizationsare available for the different result types. Some of them show the problematic areas that havebeen detected, and its just one click to start a ROMES and synchronize it to that position in themeasurement file to drill down into deeper analysis. Others will aggregate data from differentfiles to get an overview of a whole set of measurements.

    In summary the tool should simplify repetitive tasks occurring in the operational networkoptimization business and boost your daily work with ROMES by supporting you in doing thesethings:

    Find problematic areas in radio communication networks faster

    Avoid manual analysis of measurement files where no problems exist

    Shorten file-scanning times in ROMES by only showing parts of the measurement file

    Provide an overview over a set of files

    Combine data from various files to build KPIs summaries

    R&SROMES NPA Network Problem Analyzer

    New Features

    User Manual 1510.9276.02 - 4.63 16

    1.3.1 Version 4.63

    This version contains several important improvements in the usability and offers new analysismethods and options.

    1.3.1.1 Analysis Modules

    As an extension to the N17 Neighborhood Analyser Plug-In, a Handover Analyzerhasbeen added for LTE and TETRA networks. This analyser offers a geographicaloverview of the actual handover positions and several statistics on handover successand duration. The whole functionality is described in Handover Analysis chapter.

    The Coverage Plug-In N15 has been improved to also visualize CDMA 2000 andEvDOscanner data in the same way as the other technologies doe. Refer to theCoverage Analysis description for more details>. Additionally the CDMA 2000 / EvDOhandling the Cell Database has been improved.

    The TETRA Voice Analysis has been extended to extract the most important KPIs from

    the new SAIL interface supported by ROMES 4.63. For a list of KPIs and trigger pointsused to calculatze those, refer to the Key Performance Indicatorsection in the VoiceCall Analysis chapter.

    1.3.1.2 GUI

    Most of the map views now offer the possibility to show relations between elements onthe map using lines. For example, the handover analyzer (see above) shows lines fromthe handover event to the involved basestations when appropriate cell data is available.Refer to the chapter Map View for more information.

    Data filtering has been enhanced to support page specific context filters. These contextfilters work in a similar way to the generic filters, but operate in a more analysis specificway. For example, these filters allow to filter for raster elements with a specific best

    server and keep the whole content of the raster element whereas a CellID filter in thegeneric filter can be used to show the cell footprint of a single cell (and remove all otherdata from the view).

    1.3.2 Version 4.62

    The version 4.62 contains bugfixes and some new features, adding a more flexible rasterizationprocess and a way to export data to Microsoft Excel

    TM.

    1.3.2.1 Analysis Modules

    The Scanner Coverage Analysis Plug-in has been improved to reduce the number ofelements being shown. More details in the changes in the configuration can be found inthe Coverage Analysis plug-in description.

    A frequency errorlayer has been added to the TETRA Coverage Analysis module.

    1.3.2.2 GUI

    HTML pages can now be exported to Excel files in various ways.

    Creating raster data can now done using different geographical binning strategies. TheNPA now supports automatic UTM zone detection for UTM based rasterization, besidesthe new WGS84 rasterization function. Read more in the Raster Settings section.

    New Features

    User Manual 1510.9276.02 - 4.63 17

    1.3.3 Version 4.61

    The version 4.61 is a maintenance release without new functionality, containing several bugfixes(refer to Release Notes).

    1.3.4 Version 4.60

    The version 4.60 of the NPA brings a whole bunch of new functionality, covering essential post-processing features like cell data handliing, improved map data visualization and analysismethods for new technologies like LTE and TETRA.

    1.3.4.1 Analysis Modules

    Building new networks requires setting up neighbor relations between cells to support

    smooth handovers during calls and data transactions. Such neighbor relations can bedetected and existing relations can be analyzed with the new Neighborhood Analysisdata processor for LTE and TETRA.

    ROMES 4.60 supports LTE mobile measurements newly, and the NPA handles is nowable to process that data in different terms. The existing data transaction pages arenow able to also display DQA data from LTE mobiles, and the IP analysis moduleanalyzes the message procedures. Additionally, a new analyzer for LTE MobileAnalysis has been added that works in the same way as the FTP based analysismodules for HSPA and EDGE.

    The new TETRA Mobile integration into the Voice Call KPI/SQApages and theintegration of Voice Call problem detection in the Voice Call analyzer module addsupport for the most common services used in TETRA networks.

    1.3.4.2 GUI

    The central optimization unit when analyzing drive test data is the cell, i.e. the antennaproperties. Within the NPA this is reflected in the well-known capability of managingsuch cell related data in a so-called Cell Database. That database can store anarbirtrary number of cells, technologies and operators and can also handle differentnetwork states.

    The visualization of analysis data in maps has been completely reworked and offersmuch more flexibility and performance than earlier versions. It is now possible to workoffline, accessing different map services and to display much more informationelements than before. A description of all the features can be found in the Map Viewchapter.

    The data processor configuration pages have been redesigned to offer moreconvenient modification of the data processor settings.

    The map view, several tables and the cell database window support synchronisationwhen specific elements are selected. This works on cell elements and problem spots.More information on that subject can be found in Synchronization.

    1.3.5 Version 4.50 SP2

    Service Pack 2 of the version 4.50 introduces the Quick Filtercapability in the Data Sourcewindow to reduce the number of visible files.

    User Manual 1510.9276.02 - 4.63 18

    1.3.6 Version 4.50

    Starting with ROMES 4.50, the NPA is part of the ROMES installation. Therefore its versionnumber has also been changed to match the corresponding one of ROMES.

    Besides of that change, the following major functionality packages have been introduced in theNPA:

    The main feature introduced in version 4.50 is the support of database orientedmanagement of the analysis results and rscmd files. It is possible to store all analysisresults in a single local DB, and also to have different databases on one machine.Furthermore read performance from the DB is higher than from the file-system, andorganization of measurement data is simplified. More information on that topic can befound in the Database chapter.

    The data shown in the Analysis results can now be filtered using the newly introducedfilter mechanisms. This is useful to reduce the amount of data or to concentrate on aspecific subset. Details can be found in the Filterchapter.

    The Coverage Data Processor has been extended to also process TETRA Scannerresults. It also offers special analysis results in case of that RAT, which are described inthe TETRA Specific Analysis section.

    1.3.7 Version 1.20

    A new analysis plug-in can analyze (E-)GPRS measurements. It is an additional optionand can be purchased seperately. A description on the analysis of EGDE measurementcan be found in the related (E-)GPRS analysis chapter.

    When synchronizing with ROMES, it is now possible to define which workspace shallbe loaded into ROMES to show the selected measurement. The workflow can be foundin the section Synchronization Options of the Drill Down chapter, and configuration is

    described in Workspace preferences. When using the generic signal processor, it is now possible to perform basic conversion

    between logarithmic scaled values and their linearized form. This is especially usefulwhen performing arithmetic operations like averaging on power values, for example. Adescription can be found in the Unit Converter

    1.3.8 Version 1.10 SP1

    This is a maintenance release which mainly includes bug fixes. The following features have beenadded.

    Data can be deleted from the Data Source window physically, i.e. is removed from thefile system. This feature is available from the context menu in the Data Source Window.

    The Quick Info Window has been extended to show additional information on analysisresults.

    1.3.9 Version 1.10

    This version enhances the capabilities of the GUI with new visualization widgets and newanalysis processors.

    Using the first icon, you can add folders that contain measurement data into the Data Sourcewindow. The NPA can only work with data that is shown in that Data Source window. You canalso drop folders and measurement files from your favorite file manager (the Windows Explorer,for example ) into that window to add data sources.

    Once you click on that icon, a window opens in which you can select a folder that shall be addedto the set of data source locations. The initial selection is set to the installation of the "MeasData"directory in the ROMES installation path. If you add that directory, the content of the DataSource window changes to look similar as shown below:

    Folder hierarchies are imported as existing in the file system. Each time the content of adirectory changes on the hard disk, the related element in the data source window is updated toreflect those changes.

    2 Workflows

    The main purpose of this application is to help you simplify your daily work. Therefore theapplication tries to reduce the work required for some of the most tedious tasks occurring whenanalyzing ROMES measurement files. Optimizing the workflow is the key aspect here.

    The main workflows supported by the Network Problem Analyzer are described in this chapter.

    MANAGING DATA SOURCESIn that section the process of making data available to the NPA is described.

    CELL DATA HANDLINGStarting with version 4.60 of the NPA, cell data handling is supported to visualize cellsin the map view. Managing that kind of data is covered in that section.

    RUNANALYSISRaw measurement data has to be analyzed before the NPA can show meaningfulresults. This task is explained in this section.

    SHOWANALYSIS RESULTSHTML pages are used to visualize the analysis results. The usage of the internalbrowser showing these analysis result pages is covered in this section.

    DRILL-DOWN IN ROMESThe NPA provides a quick overview of the file content. If a detailed analysis isnecessary, the powerful ROMES application is used. The communication between bothapplications is subject of this section.

    VIEW SYNCHRONIZATIONSelecting elements in a view may propagate to other views to show the same elements.The rules that are behind this synchroniuation are explained in that chapter.

    CONFIGURE THEANALYSIS PROCESSControlling the analysis process is one of the major configuration aspects the NPAprovides. The configuration of the processors is described in this tutorial.

    2.1 Managing Data Sources

    Adding data sources (i.e. folders that contain measurement files or databases) is one of the firststeps before starting the analysis process. The main place where these actions are performed isthe Data Source window, initially placed on the left side of the main window.

    A more detailed description of the database capabilities is given in the Database chapter.

    Managing Data Sources

    User Manual 1510.9276.02 - 4.63 24

    2.1.1 Adding Data Source Entries

    When starting the application for the first time, the Data Source window is empty. To add somecontent, several possible ways exist:

    Use the File|Add Folder menu entry (or press the related shortcut)

    Use the Add Data Source icon in the Data Source Toolbar

    Use the equally named entry in the context menu

    Use Drag&Drop to add data from the Windows Explorer or your favorite file manager

    When using one of the first three ways, a dialog to choose the folder is shown. Select the parentfolder you want to add to the Data Source window and click 'OK' to confirm your choice.

    Using Drag&Drop, both files and folders from the hard disk can be added. When a file is draggedinto the Data Source window, the parent folder is imported anyway to represent the data.

    2.1.2 Manipulating the Data Source Tree

    When data is imported into the Data Source Window, it is displayed in a tree-like structure. Foreach folder, the measurement files and sub-folders that also contain measurement files areshown. Folders have the icon and measurement files are displayed using a blue mini-van .

    Analysis results have a small brain icon assigned to them , as shown in the picture below.

    Managing Data Sources

    User Manual 1510.9276.02 - 4.63 25

    2.1.2.1 Context Menu

    When using the right mouse to click into the Data Source Window, the context menu of the viewopens. This context menu contains the following actions:

    Add Data Source - This contains a sub menu to add either a folder from the file systemor to add a database:

    o Add Folder- same as described aboveo Add Database - same as described above

    Remove Data Source - same as described below

    Create Folder- same as described below.

    Import Data - Import the selected data into a database

    Export Data - Export the selected data from a database into a folder

    Delete Data - same as described below

    Show Measurement File Info - shows the measurement configuration details used torecord the RSCMD file.

    Run Analysis - Starts the analysis process for the selected files. The analysis processcan be started for different configurations from here as well.

    Open Analysis Result - Opens a specific Analysis View for the selected result files.

    On each item, a context menu can be opened where several commands are available. Since thetree supports multiple selection, some of the commands operate only on a subset of the currentselection. For example, the Run Analysis command only works on measurement files. It is onlyavailable, if at least one measurement file is selected, and will only use those items for theanalysis process.

    2.1.3 Creating Sub-Folders

    Especially for databases the NPA offers a function to create new sub-folders in the currentlyselected folders. That operation works on both file system and database. When started, thefollowing dialog appears where the name of the new folder must be entered. Valid names cancontain characters, digits and spaces.

    2.1.4 Removing Data Source Entries

    Sometimes it may be necessary to remove data sources from the Data Source Window again,be it that the measurement files have been analyzed and don't need further attention, or just toget a better overview again.

    In any case, removing the data is also possible using different approaches:

    Use the File|Remove Folder menu entry (or press the related shortcut)

    Use the Remove Data Source icon in the Data Source Toolbar

    Use the related entry in the context menu

    This only works on top-level data sources. Sub-folders cannot be removed using this command.

    2.1.5 Delete Data Source Entries

    Using this feature it is possible to directly delete data from the data sources, i.e. from the filesystem. It works on folders, files and analysis results. An arbitrary set of data can be selectedand deleted.

    Deletion has to be confirmed in a special dialog first, which looks similar to the one shown below.In that dialog it is possible to restrict the deletion to a subset of the originally selected datanodes.

    2.1.6 Database

    The Network Problem Analyzer can manage the analysis results and the RSCMD files in adatabase to improve performance, simplify searching and avoid duplication of data whenorganizing it (in different folders, for example).

    To use databases it is required to have the license option ROMESN51 available on the NPAdongle. Otherwise database cannot be created or loaded.

    2.1.6.1 Use Cases

    Creating New Databases

    Before any work can be done with a database, some database must be available in the DataSource Window. This can either be done by creating a new database, or loading an existing one(that is not actually shown in the Data Source Window). Already loaded databases (i.e. visible in

    the Data Source Window) can be used to work with them, of course.

    Creation of a new database or loading an existing one is done with a wizard. Depending onwhether there is an unloaded database or not, some of the following steps might not beavailable. I.e. the content of the wizard automatically adapts to the currently possible choices.

    Action Selection

    The first page of the wizards lets one choose between creating a new databases and loading anexisting one. This page is only available if there are any unloaded databases, otherwise it isautomatically skipped and the first page is the new database definition page.

    Loading a Database

    If there is at least one unloaded (not yet visible) database available, i t can be loaded into theData Source Window from the following page. It is possible to select multiple database entries ifavailable, and a double-click on the selected entries or pressing the "Finish" button will add theselected databases to the working set.

    Importing Data

    When a database is available in the Data Source Window, it can be used in very similar ways asthe file-system folders shown there. The main difference is that data cannot be copied as in thefile-system, the content of the database must be filled before any other actions can be started.

    Filling the database is done using pairs of analysis results and measurement files. For example,selecting a measurement file X.rscmd in the data source window that has results processed withthe "Default Configuration" and with another configuration named "My Config", the twocombinations of X with the configurations can be imported.

    Measurement files without any result cannot be imported into the database. As described in theparagraphs below, measurement files are automatically removed from the database once thelast configuration for that file in the database is deleted.

    Data import can be started using the related entries in the main menu or the context menu of theNPA main window resp. Data Source Window. These menu entries are available once at least

    one possible measurement file and a releated analysis result is selected. The target database iseither defined in a dialog similar to the database selection dialog shown above, or it is selectedusing the related context menu entries.

    Alternatively it is possible to use drag&drop operations to import data from the file system oranother database into a specific database. This can be done by dragging the appropriateselection and dropping it on the database icon in the Data Source Window.

    Exporting Data

    Analysis results and measurement files imported into the database can be turned back into filesagain using the export mechanisms provided by the related context menu or main menu entriesresp. using drag&drop.

    Managing Data Sources

    User Manual 1510.9276.02 - 4.63 30

    When the export is started using the "Export Data" menu entries, the destination folder has to bechosen using a directory browser dialog as shown below. When confirmed with "Ok", the actualexport is started.

    Again, an alternative way to start the export is to drag data stored in a database and drop it overa file-system folder in the Data Source Window.

    Data stored in the file system can also be "exported" to another folder. In this case, the data issimply copied from one directory to the other.

    Data Organization

    The content of a database is always organized in folders. There are two folders that have aspecial meaning and cannot be managed directly. The first on is the "Imported/All" folder. Itcontains all files imported into a datbase. Showing the content of this folder might take sometime when done on a huge database. The other folder is "Imported/Unsorted&qzot;. The contentof this folder is dynamically filled with all files that are not part of any manually created folder.

    As described in seciton Create Folder, it is possible to create a user-defined folder structure in adatabase. Using drag&drop the content of the folders can be filled with already imported data. Inthe same way data can be imported directly into specific folders.

    Data is not duplicated in the database when it is available in several folders. Instead, links arecreated similar to soft-links known from the UNIX file system.

    2.1.7 Cell Database

    Many of the optimizations that can be done in a modern radio network target the basestationentity of the network, especially when it comes to analyzing the network with drivetests.Therefore it is an essential part of a post-processing software to be able to handle cell data.

    The NPA can recognize the same formats as used in ROMES, which are the Rohde&Schwarzproprietary formats ATD and CTDB, and specialized formats BUF and CDC. The most commonand preferred way of importing data into the cell database is the ATD format. Format details aredescribed in the section below.

    In the NPA there is only one cell database that is automatically created and initially empty. Byimporting data into the database it gets populated, and over time a network element history iscreated. Managing the data in the database is explained in the section Data Management.

    The database detects changes in the input data and only stores those changes with the definedtimestamps, in order to save space and to be able to analyze older measurement files with the

    related network state. In the analysis result display, that network state is displayed that relates tothe current file displayed. More details can be found in the Network Element History section.

    2.1.7.1 Unique Cell Identifier: TxID

    To find changes in the cells across different cell data files it is necessary to have a uniqueidentifier for a cell, that also provides uniqueness in the technology domain. Such an ID iscreated automatically for each cell during import and is called TxID. This TxID is derived from aset of technology specific parameters, for example from MCC, MNC, LAC and CI in case ofGSM. Additionally an identificator for the technology is added, so the overall TxID of the Cell withCI 12345 in LAC 456 assigned to an operator with MCC 262 and MNC 99 would be"G262:1:456:12345". Based on that TxID, the history is tracked and the cells are identifiedthroughout the NPA.

    2.1.7.2 Network Element History

    Besides the fact that all cell data from different technologies and operators are managed in acentral database in the NPA, the data is also organized by network state. In other words, eachcell stored in the database has a history consisting of a set of configurations where eachconfiguration has a start and an end date.

    Differential Import

    The network element history is created by importing the data into the database over time. Eachtime a file is imported, the start date of that new data is defined. The importer then checks which

    cells have changed their configuration and only imports the delta, i.e. adapts start and end datesof the existing cells and adds new history entries if necessary. This is called differential import.

    Please note that once a differential import is finished, the delta cannot be removed from thedatabase any more. It is only possible to delete sets of cells, but not specific history entries.

    Overwrite Import

    In some cases it may not desirable to use the differential import. For example, the input datamight already contain history information, or managing history data is not considered a top-priority item. In that case it is possible to simply omit the start during import (see below) and theimported data overwrites existing entries.

    2.1.7.3 Data Management

    Manipulating the content of the cell database can be done using the actions described below.These are actions to import, export and delete data. This also covers how data is displayed inthe cell database window. All these actions are available in the cell database window from themain user interface or from the File Menu.

    Cell Data Import

    Importing cell data is started using the button. Pressing that button opens a dialog that providesthe possibility to choose which file shall be imported, as show below.

    The import of cell files supports theATD, CTDB, CDC and BUF formats. The former two formatsare open, generic formats that are described in the related sections below, whereas the lattertwo are operator specific formats and not explained here.

    Due to the internal organization of the cell database it is necessary to link all cell data to aspecific network operator. In many technologies the parameters MCC/MNC are used to specifiysuch a specific network. When this information is missing in a file, the operator can be setexplicitly in the import dialog. If cells of different operators shall be imported, the informationwhich cell belongs to which operator must be put into the cell file. If the MCC/MNC is not setexplicitly and there is no such information found in the imported file, the user will be asked toprovide this information manually:

    Specifying an start date for the differential import is also possible in the import dialog. If such adate is provided, the newly imported data becomes valid from exactly that date on. I.e.measurement data recorded before that date will not be linked to the cell information imported inthat step. Data valid before the import but different to the newly imported data will becomseinvalid from that date. It is however still available in the database to be linked with oldermeasurement files.

    Once the import details are specified and confirmed using the 'Ok' button, the import process

    starts. Progress is reported during the import process, which may take some time depending onthe input data size and the already available history.

    Cell Data Export

    Cell data stored in the database can be exported into the ATD or CTDB format again, using thebutton in the cell database window or the "Export Cell Data" entry in the File menu. A dialog isshown that is similar to the one depicted below.

    Besides the destination file, it is mandatory to define which output format shall be used andwhich technology shall be exported. The ATD format is a one technology format, and thisrestriction also applies to the CTDB format, although that can handle multi-technologyinformation.

    Additionally it is possible to restrict the exported data to a specific operator and/or a networkstate at a specified time. The format will simply reduce the number of records to the onesmatching the operator, whereas the second will only export those cells states with start and endvalidity dates that have a valid configuration at the given date.

    In case of the ATD format it is possible to define the delimiter type used to separate differentcolumns from each other. It is possible to choose between the tabulator character and a semi-

    colon.

    Pressing OK will start the actual data export process. Before an existing file is overwritten, theNPA will ask what to do in such a case.

    Displaying Data

    Imported data is shown in the "Cell Database" tree located nearby the "Data Source" window.The data is organized by technology and operator in a tree structure. Below the operator, allcells available can be found, and each cell contains the complete change log of its configurationas history child entries.

    Selecting Cells

    It is possible to select single cells or whole sets of cells using the standard selectionmechanisms of windows. Clicking on a single cells will select only that cell. When holding theShift button while clicking, ranges of cells can be selected. When holding the Control buttonwhile clicking, the cells selection state is toggled.

    When one or more cells in the cell data tree are selected, these cells will get visible in all mapviews currently opened. The map view will furthermore zoom to a rectangle where all those cellscan be seen. This is part of the view synchronization mechanisms described in more detail in theSynchronization chapter.

    History Data

    Using the tooltip, all the available attributes of a cell can be viewed, besides the change historyof that cell. Each time a differential import is done and a difference in the cells configuration isdetected, a new history entry is createed. The changes between the single history entries is

    shown in the tooltip, as illustrated in the figure below.

    Neighborhood Data

    Information about the neighbors of a cell is also provided in the tooltip shown when hoveringover a cell. The neighbors are listed with their unqiue TxIDs that have been derived from theinput data during import.

    Quick Filter

    The cell database window offers the possibility to reduce the amount of data shown in the tree tothose elements that match a set of filter critera. Therefore the Quick Filter edit field can be used.Entering a filter in that field will filter the content of the tree to those elements that match thegiven input.

    The fields that are compared to the filter string are listed when clicking an the funnel icon, whichopens a context menu. There filtering can be reduced to test specific fields of the cell elements,like TxID or Validity Date.

    The Quick Filter field is also used in the Data Source Window and its general usage is describedin the related Quick Filtersection. Please refer to that section to find out more details about theusage of that filter mechanism.

    Deleting Cell Data

    Selected data can be removed from the database again using the icon shown in the toolbar ofthe Cell Database Window. It is possible to selected operators, whole technologies or singlecells to delete from the database. However it is not possible to delete single history entries fromthe database.

    2.1.7.4 Format Details

    The open basestation formats supported by ROMES and the NPA are described in the sectionbelow. Besides those several operator-specific formats can be imported, but those are notexplained here since they are proprietary formats.

    ATD Format

    This is a Rohde&Schwarz proprietary format that consists of a pair of two f iles, an ATD and(normally) a TXT file. The ATD file is basically an INI-file that defines the columns that arecontained in the related TXT file. Both fi les are simple text files which do not contain binary data,but can be edited with a standard text editor (like Notepad).

    ATD File

    The ATD file contains the description of the data layout used in the related data file. It alsocontains a relative or absolute path to the data file. The ATD format is simply a derivate of theINI-File format used in many Microsoft Windows programs. It must contain two sections:

    A "Main" section containing a simple key-value pair "Type=ATD".

    A section "Table1" that contains the description of the input data format. The following tableshows which attributes are interpreted from the table definition section when an ATD file isimported into cell database.

    Attribute Count DescriptionFile 1 Specifies a relative or absolute path to the data file.

    Columns_Size 1 Number of columns. All additional available columns inthe data file will be ignored.

    Columns{ColumnIndex}_Name1

    1

    This defines what value is stored in the column. Thisinformation is used to map the input data to thedatabase schema described in the Data Content sectionbelow.

    1The {ColumnIndex} field is a counter from 0 up to Column_Size-1. The columns in the data file

    are intepreted in exactly that order as described in the ATD file, i.e. the first column namemapping is derived from Columns0_Name, the second from Columns1_Name and so on. Thevalues assigned to the columns are used to find a mapping to the Database Fields describedbelow.

    The following example shows the content of an ATD file definition for LTE.

    [Main]Type=ATD

    [Table1]File=file.txtColumns_Size=9Columns0_Name=eNodeB_NameColumns1_Name=PosLongitudeColumns2_Name=PosLatitudeColumns3_Name=PhyCellIDColumns4_Name=EARFCNColumns5_Name=IsDirectedColumns6_Name=DirectionColumns7_Name=PowerColumns8_Name=CellID

    Data File

    The data file contains the content of a table described within the ATD file. Rows in the data fileare separated by new line characters (\n), where colums are either separated by tabulator (\t) orsemi-colons (;). Lines starting with a hash character (#) are ignored during import.

    Each line is split into columns, and the columns content is mapped to the database field derivedfrom the column name. If no such field is found, the data is stored in the database as user-defined attribute. The technology of a line is automatically detected based on the data stored inthe line. So it is possible to import into different technologies with just one file.

    Using many user-defined attributes may slow down the import and export processes of the data,so it is normally the best way to only import data that contains fields described in the sectionbelow.

    CTDB Format

    The CTDB format is an ASCII text format for multi-technology handling. Data is organized inrows, where each row contains the data assigned to a single cell, and each cell has a set ofattributes organized in columns. Columns are separated by a ';' character.

    The first line describes how to map the data to the Fields described below. The first column mustbe a the "Tech" column describing which technology is described in the remaining part of thecurrent line. The other columns are described by their name which is used to map to a databasefield, and the supported technologies in brackets [ ], separated by #.

    2.1.7.5 Database Content

    In the tables below all data fields are described that are stored in the cell database. Data frominput files is mapped into that table, using the format description in the imported file. Datacolumns marked with one of the entries listed in the Names column below are mapped to therelated Field. Note that the names in the imported files are compared case-sensitive with themapping names, so be careful with capital and small letters.

    Each field has a pre-defined type and value range specified in the column. Basically these typesare distinguished:

    Text - A sequence of characters, not including the format specific delimiters (tabulators,new lines, semi-colons etc).

    Number - A signed integer number. Some value have a valid sub-range defined like 0..for 0 and positive numbers etc.

    Date - A single date. Can be derived from integer numbers that represent the number ofseconds since 1.1.1970 (UNIX timestamps).

    Floating Point - Decimal numbers.

    Enum - A list of values, specific to each field. For example the Technology field is anenumeration that can take one of the value listed below..

    Technology Independent Data

    The Count column describes how many times a mapping to the given field may be defined in aninput file. 0 means that this column is filled automatically during import if enough data isavailable, 0..1 means the value is optional and 1 means that a mapping to that field must be inthe file. These mandatory fields are also printed in bold.
