Module Objectives At the end of this module the trainee should be able to: View and retrieve KPI sets in Optimizer DB Visualize configuration and performance data on the Map Adjust colors and threshold values for parameters and KPIs Use profiles to store and share visualization settings Analyse daily variations in KPI values Retrieve alarm history to Optimizer



Network Data visualization How to get KPIs into Optimizer database How to visualize KPI and CM parameter values on the map

•

How to define minimum and maximum values

•

How to select colors for visualization

•

How to define labels for the map objects

How to use Dominance Area in the visualizations How to visualize Distance KPIs Other visualization examples How to store visualization selections How to view the daily variations in the KPI values How to retrieve alarm history



Network Statistics: KPIs • KPIs are grouped according to purpose and network element



Key Performance Indicators for local network elements Performance statistics are retrieved from the PM database Optimizer reads the counter values from PM database, calculates the KPIs and stores them into Optimizer database Select Tools->Network Statistics->Manage Key Performance Indicators OPTIMIZER DB

PM DB For public use – IPR applies 6 © Nokia Siemens Networks


Autoretrieve KPI sets for local network elements The KPIs which have Autoretrieve selected are automatically retrieved every day to Optimizer database.



KPI Usage KPI values from the selected date and summarization level can be visualized on the Map and Browser. Summarization levels • Day • Daily Busy Hour (element specific) • Week (always Monday to Sunday) • Weekly Busy Hour (element specific)



Retrieve KPI Sets for local network elements



Retrieve KPI Sets for external network elements









Retrieve Custom KPI Sets Custom KPIs are - additional KPIs - for local or external network elements - visible for all users

Usage of custom KPIs: - can be visualized on Map - can be listed to Browser - can be used in Capacity Analysis



Add Custom KPI



Example file for Custom KPI Retrieval

Check the date format and the file headers




Check the object types




Check the aggregation level



Existing Custom KPIs Custom KPIs are listed in their own KPI group.



Exercise Study the KPIs available for different network objects Choose one KPI and check if there are sets available in the Optimizer DB Choose a day that does not have a set in the database and retrieve a new set for one KPI

Visualization of Data Cell icon color and size, dominance area, and adjacency line color and thickness can indicate CM parameter or KPI values Visualization settings can be stored in visualization Profiles Color visualization needs also • Threshold set • Color gradient Threshold set defines the minimum and maximum values and the ranges for the parameter or KPI Color gradient defines the colors and their order for the display of the values Site icon size can vary between minimum and maximum defined in Visibility and Default Options



Select Quality Indicator

The user can select CM parameters, rule results or KPIs. Select Other... from the Cell Icon visualization Select one parameter or KPI for visualization. For public use – IPR applies 22 © Nokia Siemens Networks


Cell Icon visualization Adjust the values in the dialog



Threshold Sets



Threshold Profiles (1/2) • You can create and save new threshold profiles

• Create a new profile, based on the current one • Delete the current profile • Share the current profile with all users • Save as system default • Switch profiles



Threshold Profiles (2/2) • Create a new profile as a unique name



Adjusting Thresholds • Thresholds and gradients are common to every user • Change the minimum and maximum KPI values for the visualization (Start Source and End Source) • Out of range values are displayed with the minimum or maximum color • Start Quality and End Quality values map to Color Gradient



Gradient colors Create a new gradient Split gradient to add new colors Change existing colors Color values always between 0 and 1 Color values used in threshold set for Start Quality and End Quality



Single Color Ranges (1/2) Split the threshold set to create ranges (very good, good, not so good, bad) Every split adds a new line to the table To display the range with a single color Start Quality and End Quality must be equal



Single Color Ranges (2/2)



Cell Icon visualization Select another KPI or a parameter for Cell Size The Cell Icon KPI value is visible in the tooltip



Cell Labels Parameters and KPIs can be visualized in the cell labels



Threshold Type When a parameter has discrete values, use the Identifier threshold type Use the Quality threshold type with continuous valued parameters

Quality uses gradient colors and threshold values



Identifier uses random color for each different value e.g. Cell ID

Dominance Area visualization KPI values and CM parameters can be visualized using dominance areas Dominance areas were originally calculated with simple link loss calculations New Dominance Area is a geometrically defined polygon Dominance areas are calculated to all visible cells automatically after the feature is turned on Border areas are displayed as vectors



Dominance Areas

Coloring follows the active scope



Cell label in the tooltip Cell and area selected together Select a cell or KPI to visualize

Dominance Areas



Visualizing Border Areas BSC ID, RNC ID, LAC, SAC, … Border areas and color Use the Identifier threshold type



Exercise Turn on the dominance area visualization Use the default visibility options to change the target cells Check the information display below the map Visualize area codes on the Border area

Distance KPI visualization The Timing Advance and Propagation Delay distance KPIs can be visualized as arcs on the map, or as a histogram The process for visualizing both is very similar Timing Advance is for GSM. KPIs: • Timing Advance Distance of Max Reports [km] • Timing Advance Max Calls [N] • Timing Advance Max Distance Calls [N] • Timing Advance Max Distance [km] Propagation Delay is for WCDMA. KPIs: • Propagation Delay Distance of Max Reports [km] • Propagation Delay Max Distance Report Number [N] • Propagation Delay Max Distance [km] • Propagation Delay Max Reports [N]



Example of visualizing Timing Advance Select a cell(s) for which you have Timing Advance KPIs



Distance KPI visualization

Open the Select Quality Indicator and choose either Timing Advance for GSM or Propagation Delay for WCDMA Click “Show Distance” to refresh the map view






Distance KPI visualization You can change the transparency of the arc Default is 50, 0 is opaque



Distance KPI visualization Add distance labels to see specific figures



Distance KPI visualization The distance labels show the distance of the arc, the percentage of traffic, and also the actual number of traffic samples, respectively




Open the right-click pop-up menu to open the Histogram



Distance KPI visualization Visualize as Average MS Power (GSM) or Number of Measurements

Visualization Profiles Visualization profiles store user specific visualization settings • KPIs and CM parameters selected for visualization A new profile is a copy of the current profile Public profiles are copies of the private profiles visualization changes take effect immediately but are not saved automatically The visibility check box states are stored, the default colors are not Public profiles can be edited and deleted by other users For public use – IPR applies 54 © Nokia Siemens Networks


New Profile A new visualization profile is a copy of the active profile Give a name to a new profile Change visualization settings Save the changes



Share the Profile Profiles are private by default You can share your profile with other users Shared (public) profile is a copy of the private profile



Exercise Return all visualization settings to Default Create a new visualization profile Select parameters and/or KPI combinations to visualize Save the profile and change to default profile Move to another map area and select again the new profile
