2. Rorotika Technologies (Pty) Ltd is a South African-based company with a
strong mobile telecommunications background in both operational and
product development areas.
Rorotika focuses on developing innovative solutions in the mobile
telecommunications arena.
Rorotika is leveraging its vast knowledge of the radio environment to
design solutions in the space of radio planning, optimisation and
configuration management.
Rorotika’s Self-Organizing Network (SON) solution has the intelligence
needed to automate a radio network environment, reduce faults and
improve QoS. Products that are currently offered in the SON suite include
NetCM for network configuration management, NetPM for performance
management, NetTrax for Customer Experience Management, and
NetRevenue, a revenue reporting solution.
About Rorotika

3. Operators need to analyse data from several different network interfaces,
systems and departments in order to optimise their network infrastructure
and expenditure, while growing ARPU, profitability and market share.
Systems include Performance Management, Configuration Management,
Fault Management, Customer Experience Management and the Charging
System.
Challenges facing operators:
Isolation of network subsystems hinders data analysis
Fault reporting is dispersed across systems, reducing
visibility and accountability
Root cause analysis requires manual data correlation
efforts across multiple systems
Isolated systems result in ineffective methods of
prioritising faults and alarms
Lack of revenue data correlation makes it difficult to assess
the cost of faults and hinders effective prioritisation
Lack of CEM data correlation prevents consideration of
problems experienced on the ground, and identification
of their locations

4. NetTrax CEM from RanWorx integrates with Rorotika’s SON solution to provide
a comprehensive view of handset-based events, recurring network faults and
problematic routes. A feature-rich web-based interface offers powerful
reporting, drill-down capabilities and subscriber event-tracking. NetTrax also
supports Network Initiated Logging (NIL), allowing an operator to analyse
custom test routes and interval reports for target handsets in specified areas.
Handset software resides on standard smart phones, running Windows Mobile
OS, Android, Blackberry or Symbian.
NetCM provides an automated, repeatable and independent review of the status
of network parameters. This unique web-based product manages core
parameters, analyses B-numbers, identifies routing problems, and determines
BSS parameter faults. NetCM processes parameter data, identifies
inconsistencies and highlights key areas where settings do not conform to OEM
best practice or to operator-specific policies. MML scripts are auto-generated to
resolve inconsistencies and to manage planned activities. NetCM consolidates
multiple vendor technologies on one platform.
Netcm
NetPM, Rorotika’s network performance management solution, provides a
powerful, web-based interface to your network performance data.
Built on stable, proven ETL (Extract, Transform and Load) technology, NetPM
allows you to rapidly navigate critical network performance KPIs via the web or
a mobile device. Designed for simplicity, stability, visibility and control, NetPM
provides effective reporting and analysis.
Netpm
NetRevenue is a revenue data summarisation and reporting solution. Built on
technology that has been vigorously load-tested and commercially proven in
tier-1 networks, NetRevenue uses data from the IN CDR platform and extracts
valuable information about cell value and revenue trends.
This revenue data can be used by an operator to achieve effective fault costing
and to implement cost-based fault management.

With ever-decreasing revenue and escalating operational costs, operators need to automate traditional
optimisation methods to increase efficiencies. Improving QoS in multi-vendor, multi-technology
environments is complex and time consuming. Automation, inter-departmental communication and
integration are required in order to reduce operational costs while improving QoS.
Rorotika’s NetCM allows operators to automate network configuration across all vendors, network
subsystems (BSS and NSS) and technologies (GSM, UMTS and LTE). This web-based application allows
radio and core departments to manage parameters, analyse B-numbers, identify routing problems, and
pinpoint complex BSS parameter faults. NetCM automatically processes parameter information,
identifies inconsistencies and highlights key areas where settings do not conform to OEM best practice
or to operator-specific policies. MML scripts are generated to correct inconsistencies and to manage
planned activities. NetCM consolidates multiple vendors and technologies on one platform. It also
consolidates operators, enabling group-level management.
Reduce operational and optimisation costs Maximise profits
NetCM is trusted by tier one operators to
provide unique benefits that include:
Configuring of CORE and RAN on one platform, and increasing
inter-departmental efficiencies
Multi-vendor and multi-technology architecture with hundreds of
off-the-shelf reports
Rolling out of new sites and performing cutovers efficiently and
correctly whilst minimising human error
Centralising of configuration management functions and building
centres of excellence within the operator
Policing of vendors in a managed service environment to ensure
that the correct license sets and features are implemented
NetCM enables us to consolidate
all BSS / Core Vendors and
technologies under a single
platform. Within 3 months of
deployment, we noticed a
significant improvement in all our
working practices”

9. NetRevenue is a complete solution using data from the IN CDR
platform and extracting valuable information about cell value
and revenue trends.
NetRevenue loads, processes, summarises and
reports on charging data, providing accurate
revenue information for the operator at cell
level.
This revenue data enables an operator to
achieve effective fault costing and to
implement cost-based fault
management. Fault correction can then
be scheduled based on potential loss of
revenue, rather than just on traffic.
NetRevenue is built on technology that
has been vigorously load-tested and
commercially proven in tier-1 networks
in populous environments.

Customer Experience Management Solution
NetTrax from Ranworx delivers detailed statistics and failure
information directly from subscriber handsets, which allows an
operator to monitor true customer experience on their network.
Handset-based agent
Software is loaded onto industry standard smart phones that
harvest information with no user input required.
Solution respects customer privacy
Customers are informed of the data that is being harvested from
their handsets and can remove the software at any time.
No cost to end user
When commercially deployed, a free data backhaul is implemented
to avoid any financial impact on the end user.
Solution Overview

13. Configurable
The system can be left in passive mode for automated retrieval of
faults and key metrics, or set to active for hands-on fault finding.
Accurate
Use of on-board GPS allows for location accuracy.
Seamless
The system is effectively invisible to the end user, however, the
data gathered is transparent, and the user is able to “Opt Out” at
any time. Off-the-shelf support is available for Android,
Blackberry, Symbian, and Windows-Mobile platforms.
Scalable
Operators decide who and what to monitor and how to deploy. The
solution can be fully hosted or locally deployed, and allows for
integration with other tools, platforms and data-stores.
Solution Design
Cost reductions
Dramatically reduce the time and costs associated with drive
testing, fault finding and benchmarking.
Reduced churn
Improve customer experience through proactive fault finding
and improved customer service.
Workflow optimisation
A consolidated view of all customer-related fault information
across the organisation creates a streamlined resolution
process whilst providing the necessary feedback to
customers.
Focused marketing
Knowledge of the customer’s perception of the network in
specific areas can be leveraged by marketing or sales
divisions.
