By the end of this lesson you will be able to analyze the network

performance and quality based on the network model or

rich data from the call database

By the end of this lesson you will be able to analyze the network performance and quality based on the network model or

rich data from the call database

Analysis Tools

• KPI-based maps and reports

• Call trace-based maps and reports

Network Performance KPI-based Maps

KPI map layers are based on selected KPIs, showing aggregated data for a time resolution ranging from 1 hour up to all the dates included in the model

Network Performance KPI-based Maps – KPIs and Aggregation

• Select the required KPIs (the available KPIs appear according to the network vendor)

• Each selected KPI will be saved as a separate layer

Commonly Used KPIs – Example

• Bad Call Rate

• Access Failure Rate

• Dropped Call Rate

• Average Power

Network Performance KPI-based Maps – Time Range

• Date and Time Range

• Click the browse button to open the Date and Time Range dialog box.

• In the Date Range area, select a date range or specific dates.

Network Performance KPI-based Maps – Save Layer

• By default, the layers are saved to a default KPIs folder under the GIS category (folder can be edited) If you do not choose to save the layers, they can be displayed in the Detailed Table only

Network Performance KPI-based Maps – Display

• Once the KPI map is ready, a dialog box is displayed:

• Details – displays warnings generated during the map creation

• Detailed Table – displays the selected KPIs for each sector in the selection in the Detailed Table.

• Each selected KPI layer is displayed in the Layers pane, in the specified folder under the GIS category.

Network Performance KPI-based Maps – Example

• Use the sector tooltip to view the KPI summary for selected layers

• In the Detailed Table you can view individual element values

Displaying Histograms

You can display a histogram of the map layers in order to view a graphical display of the values in the layer

Displaying Histograms (cont.)

• The histogram displays the values for 100% of the data in the selected layer

• You can run a query to calculate the

percentage of items between a range

of values, as well as set the range of

values to be displayed in the

histogram

Call Trace-based Maps

• Mentor supports the following map types:

• Call Trace–based Bin Maps

• Call Trace–based Sector Maps

• Call Trace–based Event Maps

• Positioning-based maps can be created at any time from the toolbar or by right-clicking an area or sector selection

• If your selection contains both UMTS and LTE sectors, you will be prompted to select the technology to display

• In Multi-RAT environments with a UMTS and LTE call DB, you can display multi-RAT maps

Mentor uses mobile measurements and special algorithms to generate positioning-based map layers

Call Trace–based Bin Maps

The following call trace–based bin map types are available:

Most filtering options for creating the maps are similar across all map types

Performance Maps

• Performance maps display selected performance layers

based on the busy-hour call-trace

data

• If you have a license

for the call database,

you can display the data for

all hours

Performance Maps (cont.)

• Choose the Map type:

• Binned map

• Sector-level map – map will be aggregated to cell level (Model only)

Performance Maps – Map Type (UMTS)

• Ec/Io Best Server / Coverage / Coverage Peak

• Uplink RxQual Best Server

You can choose one of the following performance maps for

GSM environments:

Performance Maps (cont.)

• Choose the Data source:

• Client Model – data taken from the network model on the client.

• Rich Data – data taken from the call database via the Mentor server.

• If you choose to use the call database , additional filtering options will be available

• Choose the Date and time

Selecting the Map Filters

• Click Add New Filter and select

a filter from the list of available filters

• The available filters and their options depend on the data source, vendor, and technology used.

By default, maps display all RABs You can filter the RABs as well as select additional filters

Map Filters

• Profile – select whether to display the map for indoor or outdoor calls, or for all call including those not identified as

being indoor or outdoor

• Mobility – select whether to display the map for static or moving calls, or for all calls including those not identified as being static or moving

• Speed – select whether to display the data for all mobiles or filter the data according to specific IMEIs or IMSIs

• RAB Group – select single, multiple or all RABs

• Release Cause – filter the data according to the release cause.

• Networks – select whether to filter the subscriber networks By default, maps are displayed for all networks identified in

the database

Map Filters (cont.)

• Select Mobiles – select whether to display the map for all terminals in use in the network, or filter it according to a list,

file, or expression

• Device Type – select the device models by which to filter the data.

• Device Capabilities – select the device capabilities by which to filter the data

• Establishment Cause – select one or more causes for the call establishment

Performance Maps – Example

Ec/Io Best Server Map

Drop Maps

Drop maps display the geographical distribution of the dropped calls

Drop Maps – Example

Traffic Maps (UMTS)

• Map type:

• Busy Hour Minutes of Use (model)

• Busy Hour Total Number of Users (model)

• Busy Hour Traffic (model)

• Downlink Throughput / Throughput Peak / Volume

• Number of Calls

• Number of Distinct Users (rich data)

Virtual Drive Test Maps

• Data for the virtual drive test is usually taken from the Call DB via the

Mentor server

The virtual drive test map enables you to display an immediate visualization of all call flow events associated with

specific sectors and terminal handsets, according to a specific time

Virtual Drive Test – Map Layer

You can view the virtual drive test on the map area, or display its details in the Event Viewer.

Virtual Drive Test – Event Viewer

You can use the Event Viewer to view the details of any of the calls that took place in the virtual drive test (right-click the virtual drive test layer to display the Event Viewer)

• The left pane shows call-related details, for example IMSI and type

Event Viewer – Example

Event Viewer and Map

• Show Servers – displays the serving sectors for each point

• A solid line represents active sectors, and a dashed line represents candidate sectors

• Show in Event Viewer – selects the relevant call and event in the Event Viewer

Right-clicking on each point in the map displays a menu enabling you to:

Event Viewer – Main Operations

• Filter events or list of calls

• Search for selected text

• Export and Import events

• Display the actual contents of the selected event.

• Display all the mobiles associated with the selected calls at maximum zoom

Drop and Access Failure Maps

• Drop Maps display all drops (except for drops caused by access failure) reported in the network or in an area or sector selection

drops caused by access failure

Mobile Drop Maps – Example

All Reasons

Selected Reasons

Mobile IRAT Maps

Mobile IRAT Maps display IRAT handover events indicating a shift from the LTE network to the UMTS network,

or from the UMTS network to the GSM network

CSFB Maps

In order to display CS calls, mobiles in LTE networks must move to the underlying UMTS network

CSFB Maps display the circuit-switch fallback events from an LTE to a UMTS network
