Rorotika Self Organising Network (SON) Solution

  1. 1. Rorotika Technologies (Pty) Ltd is a South African-based company with astrong mobile telecommunications background in both operational andproduct development areas.Rorotika focuses on developing innovative solutions in the mobiletelecommunications arena.Rorotika is leveraging its vast knowledge of the radio environment todesign solutions in the space of radio planning, optimisation andconfiguration management.Rorotika’s Self-Organizing Network (SON) solution has the intelligenceneeded to automate a radio network environment, reduce faults andimprove QoS. Products that are currently offered in the SON suite includeNetCM for network configuration management, NetPM for performancemanagement, NetTrax for Customer Experience Management, andNetRevenue, a revenue reporting solution.About Rorotika
  2. 2. Operators need to analyse data from several different network interfaces,systems and departments in order to optimise their network infrastructureand expenditure, while growing ARPU, profitability and market share.Systems include Performance Management, Configuration Management,Fault Management, Customer Experience Management and the ChargingSystem.Challenges facing operators:Isolation of network subsystems hinders data analysisFault reporting is dispersed across systems, reducingvisibility and accountabilityRoot cause analysis requires manual data correlationefforts across multiple systemsIsolated systems result in ineffective methods ofprioritising faults and alarmsLack of revenue data correlation makes it difficult to assessthe cost of faults and hinders effective prioritisationLack of CEM data correlation prevents consideration ofproblems experienced on the ground, and identificationof their locationsSelf-Organising Network solutionRorotika’s SONMulti: Vendor, Technology, Node, HandsetExpert-driven inference engineRevenue-driven fault costing and rankingDiscrepancy resolution or recommendation reportingCorrelation of network-based (PM) vs handset-based (CEM)fault informationGeo-accurate fault detection and root-cause analysisRoute tracing, B-number analysis, policy management, sitevalue and upgrade / downgrade reportingCost-effective technologiesStrategy-based BI and reporting (Revenue vs KPI)GIS interface for easy navigationConfiguration of new and existing sites and Node BsIdentification of PM-related KPI degradation due tomisconfigurationAuto-discovery of configuration faults and recommended fixesHandset test route analysis with replay and street view analysis
  3. 3. NetTrax CEM from RanWorx integrates with Rorotika’s SON solution to providea comprehensive view of handset-based events, recurring network faults andproblematic routes. A feature-rich web-based interface offers powerfulreporting, drill-down capabilities and subscriber event-tracking. NetTrax alsosupports Network Initiated Logging (NIL), allowing an operator to analysecustom test routes and interval reports for target handsets in specified areas.Handset software resides on standard smart phones, running Windows MobileOS, Android, Blackberry or Symbian.NetCM provides an automated, repeatable and independent review of the statusof network parameters. This unique web-based product manages coreparameters, analyses B-numbers, identifies routing problems, and determinesBSS parameter faults. NetCM processes parameter data, identifiesinconsistencies and highlights key areas where settings do not conform to OEMbest practice or to operator-specific policies. MML scripts are auto-generated toresolve inconsistencies and to manage planned activities. NetCM consolidatesmultiple vendor technologies on one platform.NetcmNetPM, Rorotika’s network performance management solution, provides apowerful, web-based interface to your network performance data.Built on stable, proven ETL (Extract, Transform and Load) technology, NetPMallows you to rapidly navigate critical network performance KPIs via the web ora mobile device. Designed for simplicity, stability, visibility and control, NetPMprovides effective reporting and analysis.NetpmNetRevenue is a revenue data summarisation and reporting solution. Built ontechnology that has been vigorously load-tested and commercially proven intier-1 networks, NetRevenue uses data from the IN CDR platform and extractsvaluable information about cell value and revenue trends.This revenue data can be used by an operator to achieve effective fault costingand to implement cost-based fault management.Netrevenue

  5. 5. NetcmWith ever-decreasing revenue and escalating operational costs, operators need to automate traditionaloptimisation methods to increase efficiencies. Improving QoS in multi-vendor, multi-technologyenvironments is complex and time consuming. Automation, inter-departmental communication andintegration are required in order to reduce operational costs while improving QoS.Rorotika’s NetCM allows operators to automate network configuration across all vendors, networksubsystems (BSS and NSS) and technologies (GSM, UMTS and LTE). This web-based application allowsradio and core departments to manage parameters, analyse B-numbers, identify routing problems, andpinpoint complex BSS parameter faults. NetCM automatically processes parameter information,identifies inconsistencies and highlights key areas where settings do not conform to OEM best practiceor to operator-specific policies. MML scripts are generated to correct inconsistencies and to manageplanned activities. NetCM consolidates multiple vendors and technologies on one platform. It alsoconsolidates operators, enabling group-level management.Reduce operational and optimisation costs Maximise profitsNetCM is trusted by tier one operators toprovide unique benefits that include:Configuring of CORE and RAN on one platform, and increasinginter-departmental efficienciesMulti-vendor and multi-technology architecture with hundreds ofoff-the-shelf reportsRolling out of new sites and performing cutovers efficiently andcorrectly whilst minimising human errorCentralising of configuration management functions and buildingcentres of excellence within the operatorPolicing of vendors in a managed service environment to ensurethat the correct license sets and features are implementedNetCM enables us to consolidateall BSS / Core Vendors andtechnologies under a singleplatform. Within 3 months ofdeployment, we noticed asignificant improvement in all ourworking practices”Sidney Arnold: GM NetworkOperations MTN SA““NetCore allows for daily NSS tasks to beperformed without forcing changes in ourprocesses as well as enabling seamlessinter-departmental interaction”Adrian Pelsar: Manager DCG MTN SA“NetRan has been an invaluable system toeffectively and efficiently manage configurationsin our network”Ajeeth Rampall: Radio Planning andOptimisation Regional Manager Vodacom SA

  8. 8. NetRevenue is a complete solution using data from the IN CDRplatform and extracting valuable information about cell valueand revenue trends.NetRevenue loads, processes, summarises andreports on charging data, providing accuraterevenue information for the operator at celllevel.This revenue data enables an operator toachieve effective fault costing and toimplement cost-based faultmanagement.
