RANOPT

……AIRCOM’s solution to measurementAIRCOM’s solution to measurementbased post processing based post processing



What is RANOPT?

▪ For multi-technology drive measurement based post processing and analysis/troubleshooting.- WCDMA, GSM, GPRS, EDGE etc

▫ Load files, ‘as required’, ‘bulk’ or ‘as collected’▫ ‘Filter’ files before analysis. eg date, location, filename etc▫ Geographic display▫ Spreadsheet reports▫ File synchronised playback/replay▫ Layer 3 messaging browser

▪ Designed in conjunction with a leading European operator

▪ Part of Enterprise Suite – provides integrated solution across planning, performance monitoring and optimisation

Requirements for Supporting Logging Equipment

• Agilent Nitro – Require Agilent SW on loader - SD5 file access given via AGILENT dlls

• TEMS 6/6.1 - TEMS specific ‘Export Plan’ required. Used in TEMS SW to export log file into RANOPT compatible format

We have tested and support the following phones w.r.t TEMS 6/6.1

V800 (sony Ericsson),

Z1010 (sony Ericsson),

R520m (sony Ericsson),

T610 (sony Ericsson),

Nokia 6630

Theoretically is should be possible to support the following phones (obtained unofficial spec TEMS Investigation 6.1 -- Hexadecimal Strings in Text Format Logfile Export.pdf)

All Motorola

All Nokia

All Qualcomm

Sony Ericsson T610/T616/T618, T68, T62u, R520M

V800, V802SE, Z800i, Z1010, S710a

•However spec obtained does not correspond to files causing issues with TEMS support



How is it deployed?

▪ Client Server/Terminal server

▪ Standalone

and what SW is Required?▪ Oracle 9i with partitioning and spatial options - hence the need for Oracle Enterprise.

▫ Oracle SQL*Net

▫ Oracle Call Interface (OCI)

▫ Oracle Objects For OLE

▫ Oracle ODBC

▪ Microsoft Office -Excel ▫ 2000

▫ 2003

▫ XP



Using RANOPT – Issues that need to be considered

▪ RANOPT Oracle DB maintenance▫ Not maintaining DB leads to performance issues

▫ AIRCOM can help and educate on system architecture▫ AIRCOM can provided SW upgrades and suggest when best to apply

▫ Data Deletion

▪ Manual

▪ Automatic – data is too old, AIRCOM can provide deletion scripts

▫ Data Aggregation ( Some customers are requesting this)

▪ Day to week

▪ 50m – 100m

▫ Data Archiving – Required?

▪ Site DB Maintenance▫ Needs to be synchronised and kept up to date from IMS/OMC for correct site

information and analysis work



Optimisation - What are we trying to do?



Optimisation Process – Drive Test Based

▪ Determine clusters for acceptance

▪ Characterise performance

▪ Ensure correct site configuration

▪ Parameter settings

▪ Neighbours

▪ Powered

▪ Stable

▪ Drive tests

▪ Process data

▪ Call statistics

▪ Key measurement data

▪ Key measurement events

▪ Neighbour analysis

▪ Analysis

▪ Remodelling

▪ Reconfiguration

▪ Parameters

▪ Neighbours

▪ Report Hardware requirements



▪ Pilot and Service Optimisation

▫ Pilot performance

▫ Service Performance

▫ Hardware/parameter fine tuning

▪ Verification (Site)

▫ Pilot Coverage

▫ Service functionality

▫ Crossed Feeder check

▫ Coarse azimuth and tilt adjustments

▪ Pilot Network Optimisation

▫ Pilot coverage/pollution

▫ Fine azimuth and tilt

▫ Neighbours

▪ Pilot and Service Optimisation

▫ Pilot performance

▫ Service Performance

▫ Fine azimuth and tilt

▫ Pilot parameter

▫ Neighbour modifications

Starting to Optimise with RANOPT



The Main Tool Bar



Front End Data Loading - File Load Wizard

First time File load Wizard used –

need to specify RANOPT DB server

details

File load Wizard opens and guides through process for data load



File Loading – What you will see…

File is moved

to ‘in’ folder

Monitor progress

of file load



File Loading – What happens as loading completes

File moves to

‘out’ folder

Adds new file

to database tree



Why Use Filters?

Filters provide a method of displaying and analysing data:

▪ Used to string multiple log files together

▪ To compare scanner and handset measurements

▪ To filter out (exclude) results by threshold or anomalies

▪ To bin data by time/distance or grid

▪ To analyse specific scrambling codes, BSIC/BCCHs, networks or polygons.

▪ Can save the modified log file(s) to use later

▪ Allows grouping of similar log files for easy retrieval using Windows style folders

▪ Can share filters with other users by making them public filters…



▪ Use to Creating new filters/folders

Filter Manager Options

▪ Right clicking on the empty space in the Filter Manager gives the following options

▪ Right clicking on a filter in the Filter Manager gives the following options

Option to use the extends of the 2D view to filter the data . The 2D view extents are used as a polygon

▪ Create/delete and modify existing filters

▪ Quick add/remove from 2D view



Filtering - How to Choose Data for Analysis

▪ To selecting data set to analyse – open the Filter Manager

Right clicking opens Filter Criteria Wizard to create new filter selection

Right clicking on filter opens new Filter Criteria Wizard with filter selection criteria used as a template

Selection criteria, manipulation and link to site/cell info

Includes filters into the GIS



Filtering – Options for Data Selection and Manipulation

▪ Selection/Filtering of measurement data via Filter Criteria

▪ Filter data based on:

▫ Date/Time

▫ Technology

▫ Polygon/Region

▫ Equipment Type and Network

▫ SC, BSIC/BCCH

▪ Data Manipulation:

▫ Binning (see slide Binning Techniques )

▫ Exclusion rules ( see slide Filter Manager - Rules Editor)

▪ Filters based on selection site filters creates from other Enterprise modules

▪ Cell database snapshots association (see slide Filter Manager- Snapshot Manager)



Filtering – Applying the Filter and Beginning Analysis

▪ Clicking ‘OK’ on the Filter Criteria Wizard – Choosing ‘Apply’ - Applies (selects) the required data and provides a progress bar. Analysis can begin following this

Opens the Voice Summary Report for analysisOpens the Scanner Summary Report for analysis



Beginning Optimisation Analysis

▪ Scanner and Voice Summary reports can also be accessed via the Filter Manger

Opens the Voice Summary Report for analysisOpens the Scanner Summary Report for analysis



Where is the Drive and What are the Radio Conditions Like?

▪ Displaying the route on the GIS – display Ec, Ec/Io, Rx Lev, Rx Qual etc..



So Where are the Problems?

▪ Checking the events and displaying site, routes etc



How to Configure GIS Views

Update neighbour plan for site database directly from report

Shows neighbour plan for each cell for more focussed analysis



Similar Analysis for Data Trouble Shooting

Provides KPIs

and drill down analysis of data events

• Data Summary Report can be use to analyse data transfers in detail, providing all data events and drill down analysis to investigate cause of failures. Events can be plotted on the GIS as required

• The report has a number of worksheets which provide data for analysis and trouble shooting. Details are provided on the slide: Data Summary Report
