Network Statistics: KPIs

KPIs are grouped according to purpose and network element


6/66



Key Performance Indicators for local network

elementsPerformance 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->Key Performance Indicators

KPI Usage

KPI values from the selected date and summarization levelcan be visualized on the Map and Browser.

Retrieve Custom KPI Sets

Custom KPIs are

- additional KPIs

- for local or external network elements

- visible for all users

Usage of custom KPIs:

- not used for Optimizer tools

-- can be visualized on Map

- - can be listed to Browser

- can be used in Capacity Analysis


13/66



Add Custom KPI


14/66



Existing Custom KPIs


15/66



Example file for Custom KPI Retrieval

Check the dateformat and the fileheaders


16/66




Check the

object types


17/66




Check theaggregation level


18/66



Exercise

Study the KPIs available for different network objectsChoose one KPI and check if there are sets availablein the Optimizer DB

Check the controllers that have data (BSCs or RNCs)Choose a day that does not have a set in the database andretrieve a new set for one KPI (e.g. CS Traffic)

Make sure that some BTS, Cell and Adjacency (ADCE) KPIsare available for the selected day

Cell icon color and size, dominance area, and adjacency line color andthickness can indicate CM parameter or KPI values

visualization settings can be stored in visualization Profiles

Color visualization needs also Threshold set

Color gradientThreshold set defines the minimumand maximum values and the ranges

for the parameter or KPIColor gradient defines the colors and theirorder for the display of the values

Cell icon size can vary between

minimum and maximum defined inVisibility and Default Options

Visualization of Data


21/66



Select Quality Indicator

The user can select CM

parameters and KPIsSelect Other... from theCell Iconvisualization

Select one parameter

or KPI for visualization


22/66



Cell Icon visualization

Adjust the values in the dialog


23/66



Threshold Sets


24/66



Threshold Profiles (1/2)

Create a new

profile, based onthe current one

Delete thecurrent profile

Share thecurrent profilewith all users

Save as system

default Switch profiles

You can create and save new threshold profiles


25/66



Threshold Profiles (2/2)

Create a new profile as a unique name


26/66



Adjusting Thresholds

Thresholds and gradients arecommon to every user

Change the minimum andmaximum KPI values for the

visualization(Start Sourceand End Source)

Out of range values aredisplayed with the minimum or

maximum color Start Qualityand End Quality

values map to Color Gradient


27/66



Gradient colors

Create a new gradientSplit gradient to add new

colors

Change existing colors

Color values alwaysbetween 0 and 1

Color values used inthreshold set for

Start QualityandEnd Quality


28/66



Single Color Ranges (1/2)

Split the threshold setto create ranges (verygood, good, not so

good, bad)Every split adds a newline to the table

To display the rangewith a single color StartQuality and EndQualitymust be equal


29/66



Single Color Ranges (2/2)


30/66



Cell Icon visualization

Select another KPI or a parameter for Cell Size

The Cell Icon KPI value is visible in the tooltip


31/66



Cell Labels

Parameters and KPIs can be visualized in the cell labels


32/66



Threshold Type

When a parameter has discrete values, use the Identifierthreshold typeUse the Qualitythreshold type with continuous valued parameters

Qualityuses gradientcolors and thresholdvalues

Identifieruses random colorfor each different value e.g.Cell ID


33/66















34/66



Dominance Area visualization

KPI values and CM parameters can be visualized usingdominance areas

Dominance areas were originally calculated with simple link

loss calculationsNew Dominance Area is a geometrically defined polygon

Dominance areas are calculated to all visible cellsautomatically after the feature is turned on

Border areas are displayed as vectors

Exercise

Turn on the dominance area visualization

Zoom and pan to get an idea on the calculation speed

Use the default visibility options to change the target cells

Check the information display below the map

Distance KPI visualization


40/66




The Timing Advance and Propagation Delay distance KPIscan 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


41/66



Example of visualizing Timing Advance

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



42/66




Open the SelectQuality Indicator andchoose either Timing

Advance for GSM orPropagation Delay forWCDMA

Click Show Distance

to refresh the mapview


43/66



44/66




You can change the transparency of the arc

Default is 50, 0 is opaque



45/66




Add distance labels to seespecific figures



46/66




The distance labels show the distance of the arc,the percentage of traffic, and also the actualnumber of traffic samples, respectively


47/66



48/66




visualize as Average MS Power (GSM) orNumber of Measurements



49/66









How to use Dominance Area in the visualizations (optional)





Visualization Profiles


50/66



visualization profiles store userspecific visualization settings

KPIs and CM parameters selectedfor visualization

A new profile is a copy of the currentprofile

Public profiles are copies of theprivate profiles

visualization changes take effectimmediately but are not savedautomatically

The visibility check box states are

stored, the default colors are notPublic profiles can be edited anddeleted by other users

New Profile


51/66



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


52/66



Profiles are private by default

You can share your profile with other users

Shared (public) profile is a copy of the private profile

Exercise


53/66



Return all visualization settings toDefault

Create a new visualization profile

Select parameters and/or KPIcombinations to visualize

Save the profile and change to

default profileMove to another map area andselect again the new profile

Analysing KPI Trends


55/66



KPI Trends lets you

- analyse one or more KPIs over a period of time- analyse one or more objects

- compare different KPI trends in one view

- see the analysis result as a line or scatter chart- print the analysis result

- save the analysis result as an image or a csv file

Alarm History


61/66



Alarm history can be used

to specify the optimization scope

after optimization to check if alarms are the cause for performance problems

The user can list

active alarms

all alarms

Alarm history can be started for a cell or a site

WCDMA objects included in retrieval: WCEL-WBTS-RNC

GSM objects included in retrieval: BTS-BCF-BSC-TRX
