1.1 Introduction

The purpose of NPA is to archive and process indicators and OMC-R PMcounters. It then presents the results as a graph or a report.

Performance data is periodically transferred from the OMC-R to the

Alcatel-Metrica/NPR system, as shown in the following figure.

The Metrica parser reads the data and transforms it into the standardized dataload format. This data is loaded into the performance database by the NPRloader. The NPR loader then implements the mapping of the Alcatel BSSperformance data counters to the Alcatel type-specific data model.

The raw performance data is aggregated daily, weekly and monthly. Metricaproduces summary data that is stored in the performance database. NPAgenerates reports and graphs displaying the summary data.

2.1 Creating Warning Reports and Graphs

This section describes how to generate GSM, GPRS. and RMS warningreports and graphs. See View GSM Warning Thresholds and Parameters ( Section 1.4.1) for information on how to view the associated alarm predicateand availability thresholds.

2.1.1 GSM Threshold Warning Reports

You can create GSM threshold warning reports of potential network problemsfor a cell, BSC, or user defined area. The report lists cells or BSCs in thenetwork where the alarm predicate has been exceeded. This can be for theprevious day (including up to 10 previous days) or previous week (includingup to 10 previous weeks).

When creating a threshold report, you can choose either:

2.2 Creating Evolution Graphs

Use the Evolution menu to generate graphs that show the evolution ofindicators.

When a graph is displayed per hours or hours/days the raw data array is

used. To have 24 values (one per hour) a normalization and interpolationis performed on the array.

Normalization is the aligning process of the raw data arrived at irregular

intervals, so the values are available for exact 60 minutes period.

Interpolation is the process of calculating equivalents for exact 60 minute

periods that are ’missing’ after normalization.

When a graph is displayed for the current day (hour/day), the raw data arrayis normalized/interpolated and the result will be a 24 values array (one perhour even if the day is not finished).

2.2.1 GSM Evolution Indicator GraphsYou can display or print the evolution of indicators for a selected period of time.

The graphs are for selected Transceivers, cells, BSCs, user defined area, orthe entire network.

Each graph shows the evolution and the average value. It is available:

Per hour for one day

Per hour for several days

Per day

Per week

Per month.

You can display a maximum of three graphs from a list of 16 available graphs.The TRX graphs option has a selection of per hour for days, and per day. Thefollowing table lists the options and describes them.

2.7 Creating Cell and BSC Forecast Graphs

You can display and print, in graphical form, the forecast of a cell or a BSC.

The graphs show dimensioning parameters over a selected range of days,weeks or months. If the end date is greater than the current date, the

regression is extrapolated out to the forecast day. The regression type canbe linear, logarithmic or exponential. The following table lists the optionsand describes them.

Option Description

Cell Displays the traffic parameters (RTCH, SDCCH, PCH and AGCH) for a selected cell for adaily, weekly or monthly forecast.

BSC Displays the traffic load (TCH and SCP traffic, and DTC load) for a selected BSC for adaily, weekly or monthly forecast.

Table 17: Cell and BSC Dimensioning Options

Cell DimensioningGraphs

The display is made up of four trend charts:

The Traffic RTCH graph shows the cell busy hour traffic as a forecast value,

and the cell RTCH Erlang capacity.

The Traffic SDCCH graph shows the SDCCH busy hour traffic as a forecast

value, and the SDCCH Erlang capacity.

The Paging Channel Load graph shows the PCH load as a forecast value,

and the maximum PCH load.

The Access Grant Channel Load graph shows the AGCH load as a forecastvalue, and the maximum AGCH load.

BSC DimensioningGraphs

The display is made up of three trend charts:

The Traffic RTCH graph shows the BSC busy hour traffic as a forecast value,

and the BSC RTCH Erlang capacity.

The Traffic Signaling Connection Control Part graph shows the SCCP busy

hour traffic as a forecast value, and the SCCP capacity.

The Digital Trunk Controller Processor Load graph shows the DTC

processor load as a forecast value, and the DTC processor load capacity.

Forecasting requires a minimum of two days data.There must be at least two days of data available in order to forecast a cellor a BSC.

Sample Procedure To create a per day, cell forecasting graph:

1. Select Dimensioning -> Cell -> Per day.

The Cell Dimensioning Per Day window appears.











9. Enter the number of days you want to forecast.

10. Select which regression type you want to display from the Regression Type

drop down menu.11. If the current graphs selection (Steps 2 to 10 ) are the only graphs for

display, click on [ OK ] to display them. The Cell Dimensioning Per Daywindow closes.

If more graphs are to be selected after the current graphs are displayed,click on [ Apply ] to display the current graphs. Repeat Steps 2 to 10 to select any additional graphs.

2.8 Creating Cell Hand Over Status Graphs

You can view and sort serving and target cell handover statistics, for a selectedcell over a specified range of days, using the Cell-Cell menu. Two graphs aredisplayed showing the handover statistics to/from the selected cell.

The first graph shows the following incoming intra BSC handover statisticsfor the selected cell:

The number of failed handovers due to BSS problems

The number of failed handovers due to radio failure

The number of failed handovers returning to old channel

The number of successful handovers as a stacked bar chart on the left axis

The percentage of failed handovers returning to old channel

The percentage of failed handovers as overlays on the right axis.

The second graph shows the outgoing intra BSC handover statistics for theselected cell.

Sample Procedure To create a graph:

1. Select Cell-Cell -> Cell-Cell Hand Over Graph....

The Cell-Cell Hand Over Graph window appears.



If you clicked on the pull down menu button, go to Step 3 .3. Click on the Select By pull down menu button in the Select Cell window (see

Figure 6 ), and select BSC, Area, OMC or Network, as required.
