    7. 7. User Interface Overview
    8. 8. Workspace • “Measurements” tab in workspace is divided to three sections: – Folders • • – – • • • “All measurements” folder in the workspace shows all files currently in the database Other user-defined folders where files can be grouped automatically, e.g., “All files from certain operator”, “All files from UMTS” Folder contents • List of all measurements in the folder selected in the “Folders” section Parameter tree • Shows all available parameters and KPIs for the selected file, measurement, or folder, depending on the selection in “Folders” and “Folder contents” sections KPIs can be displayed in graph, map, etc., or statistics can be calculated from the parameter tree Visible tab in the workspace can be changed from the bottom Tabs: – Measurements – Base stations – Maps – Data source files – Reports
    9. 9. Loading files into Nemo Analyze • Select File | Open | Measurement/BTS/Map/Report or click the Open Measurement button • Measurement files and BTS files are loaded in the database • Maps and report templates are loaded in the workspace • Note that all the files uploaded into the database need to have unique file names • The added files will appear in the workspace view in the left-hand side of the Nemo Analyze main window
    10. 10. Organize measurements • • • By default, all added measurement files go into the All Measurements folder Measurement files can be further grouped to folders 3 different folder types: – Drag-and-drop folder • – Search folder • • • – User can manually drag-and-drop the files to the folder User sets a criteria, based on which the measurement files are automatically added to the folder Folder contents is updated automatically when new files are added to the DB E.g. all files from last week, all files from UMTS, all files from certain operator Query folder • • Files to the folder are filtered based on user-defined SQL query E.g. all files with dropped RRC connections
    11. 11. Organizing Measurements -Drag&Drop Folder Right click on Measurement, Add Folder/Drag & Drop… Drag & Drop measurement file into new folder Create a new folder, input folder name.
    12. 12. Removing Files from Drag&Drop Folder Click on Measurement, Right click, Remove from Folder…
    13. 13. Organizing Measurements -Intelligent Folder Right click on Measurement, Add Folder/Query… Once the query is defined, Nemo Analyze will go through the measurement files in the database and automatically add all relevant files to the query folder. Predefined queries or custom queries can be used to define the folder.
    14. 14. Organizing Measurements -Intelligent Folder
    15. 15. Joined Measurement • • • • With Nemo Analyze it is possible to join separate measurement files into a joined measurement. Joined measurements will be handled as one measurement file. Note that you cannot join overlapping measurement files. Files must have been recorded at different times. Right-click on All Measurements and select Add Joined Measurement The joined measurement appears in the Workspace and you can now drag & drop measurement files in it. Joined measurements are identified with a symbol.
    16. 16. Joined Measurement
    17. 17. Joined Measurement 15thSep2005 will be treated as a single measurement. Drag & Drop measurement files to joined measurement folder created.
    18. 18. Organize measurements • • • Right-click on “All measurements” folder  Organize.. In the Organize Measurements dialog you can conveniently handle and organize large sets of measurement files In the Organize Measurements dialog you can create new folders, make joined measurements, and remove files from drag & drop folders. Right-click in the left-hand panel to create new folders.
    19. 19. Find Filters in the Workspace • Quick filtering of all files in the database, or files in a specific folder • Quick filtering of a KPI in the parameter tree
    20. 20. KPI Descriptions and Default Color Sets • Right-click on a parameter in parameter tree Description – KPI descriptions for all parameters, where the KPI name is not self-explanatory • Right-click on a parameter in parameter tree Change Defaults – Default colorset user for the parameter in the map can be changed – Settings of statistical calculation can be changed

    27. 27. Automatic Color Set Generation for a Value Range • Color is assigned to each value within a user-defined range • Useful when creating color sets for scrambling code, cell id, BSIC, etc.
    28. 28. Grid • • Search filter Export to MapInfo tab file, excel, csv file
    29. 29. Color Scatter and Surface Graph • Plot and analyze the relations of three different attributes • Can be used, e.g., as combined scatter and density histogram – Color/height indicates the number of samples
    30. 30. Binning in Color grid and Scatter • Binning in scatter and color grid: – Graph can be divided into 4 user-definable areas – Number of samples in each bin is shown • Right-click on the graph Bin Data…
    31. 31. Timeline • • • • • Control that shows the timeline of a measurement file Troubleshooting events can be visualized in the timeline Timeline synchronized with other controls  easy to jump to problem areas in the file Quick overview of the measurement file and its problems A time range can be selected from the timeline and parameter values or statistical report from that range can be fetched
    32. 32.

    38. 38. Statistical reporting • • Reporting is based on Crystal Reports Report templates provided along with the SW, including all essential KPIs: – Service performance report, KPIs on: • – Voice call, video call, PDP context activation, attach, MMS, SMS, FTP, HTTP, WAP, POP3, SMTP, PoC, Network performance report, KPIs on: • GSM, GPRS, EDGE, WCDMA, HSDPA, CDMA, TDMA, TETRA
    39. 39. Statistical reporting • • • • Reports can be run over single file or multiple files Inside the selected measurement files, data to be reported can be filtered further on based on: – Time frame – System – Band – Area – Combination of above attributes For example: Report from all measurements from last week in the DB, from WCDMA in city X Reports can be configured: – KPIs to be included – Range and binning step for the cumulation and density histograms – Threshold and threshold condition (e.g. percentage of RSCP samples <= -95dBm)

    44. 44. Troubleshooting 1. 2. Right-click on log file or folder UMTS  UMTS Troubleshooting (or GSM)
    45. 45. User-Defined SQL Queries • • • User can write SQL query, show the results in graph, and add the custom query to menu as a new parameter DB schema is provided along with the software The database has an open ODBC interface – Any third party SQL DB tool can be used to fetch data from the DB
    46. 46. Adding Custom Queries to Analyze UI Manual Query • Own queries can be added from query manager 1. Query manager -- > add manual query 2. Give name to the query 3. Select ”Edit SQL manually” checkbox 4. Type the query in 5. Set aliases for different graphs, i.e. what column will be in x-axis, what will be in y-axis, etc. 6. When finished, the query is available in the “User” branch in the parameter tree in Analyze workspace.
    47. 47. Adding Custom Queries to Analyze UI Query Wizard • • Simple queries can be done with query wizard • Time-based correlation is not done – If two selected tables don’t have relation, result set will be Cartesian product of the tables! Joins are made automatically between tables that have relationships Step-by-step procedure: • • • Select tables from where data is get • • Set filtering conditions for results Select columns to be displayed from the table(s) Select column for ordering the results, if time based ordering is not sufficient Define aliases between controls and result columns (which columns will be x and which will be y in graph etc.)
