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

How Does RANOPT Help?
Saving time and money Focus on problems/troubleshoot quickly Bulk Loading – data warehouse using Oracle Database Common database for data sharing across organisation Floating licenses for use on any machine having RANOPT SW Data aggregation/management over time
Can be used throughout the optimisation life cycle Plug and play analysis modules, customised to suit any need Poor Dominance, Interference/Pilot Pollution Analysis, Call/Event Analysis,
Neighbour Analysis and Display, Data and throughput analysis Quick changes in planning DB, Analysis with planning DB – predicted
coverage comparison, drive data incorporated model tuning.
Can check if optimisation changes made make the right difference in the network – increase revenue
Network benchmarking and trending capability

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

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)
