New RA & Fraud Challenges
 Industry definitions are rapidly changing
 New complex data services are being populated across operator service offerings
 Shift from data pipe provider role to content integrator position
 Complex partnerships on SLA-driven and revenue-sharing basis
 New technologies and business models
(LTE, Mobile Money, rich communication services etc.)
 Proactive identification of revenue leakages,
risk mitigation, and fraud management is essential
 New set of skills and capacity required for
RA & FM staff

10. 10
Process in Selecting RA & Fraud Solution
 Mobitel RA & FM function was newly set up and required visibility & control of the
entire revenue map in terms of revenue leakages and fraudulent activities
 Creating internal capacity was also a mandatory requirement, to be executed in
parallel
 Mobitel invited leading players in the domain (based on Gartner’s Magic
Quadrant)
 Comprehensive technical evaluation process, qualified by cVidya for RA & FM
solution
 Inclusion of organizational key risks & revenue sources and defining correct control
points & KPIs are essential at the beginning of the project

Mobile Money – Mobitel

LTE Challenges
 Consumption or service based is much more
complex than transport based charging
̶ New service requirements with Shorter Time to market
̶ Complex Price plans
 Quality Of Service based rating create new
challenges for verification and re-performance
 Multiple charging policies in the same session
So…
 Do we measure usage correctly?
 Are we applying the appropriate policy?
 Are we charging according to the appropriate policy?

Big Data Analytics for Fraud Management
Using Deep Packet Inspection (DPI) and Pattern Matching is highly effective for:
 Identifying malicious calls & applications in real time
 Detecting abnormal service consumption
 Detecting subscriber frauds
 Mobile Money related Frauds (Phishing attacks)
 Detecting Tethering of Smart Phones
 Detecting Proxy Services
 Achieving visibility on OTT services

16. 16
Using DPI to identify Fraud
 Tethering performed in a commercial manner is considered to be an abusive
operation and impacts the telecom operator in several ways:
– Affecting the network planning and causing overloads
– Could force the operator to invest in expanding his network
– Harming the user experience of other legitimate users

Quicker, Richer, Better
 Cross analysis of non-correlated sources
 Accurate, fast & intelligent insights
 Reduction of time & investigation
resources
 Larger retention - storing for longer
periods of time
 Enabling RA & Fraud units to provide
services and leverage capabilities for
other non-fraud activities
