What are the primary causes of telecom fraud? Identify and audit mobile fraud and revenue assurance issues.

1. Fraud in Telecoms
Sources of operational risk
© E.O’Connor – May 2008

2. DEFINITIONS
 Definition of Fraud varies by jurisdiction but a fair summary is:
“a deception deliberately practiced in order to secure unfair or unlawful gain.”
 The Telecoms Management Forum defines Revenue Assurance as the:
“data quality and process improvement methods that improve profits,
revenues and cash flows without influencing demand.”
 Together the revenue losses from RA and Fraud can be significant

4. FRAUD
Fraudulent activities tend to fall into one of 7 categories:
 Voice – threat of impersonation for malicious or profitable motives
 Subscription – use of a legitimate subscriber’s network access for malicious or profitable
motives
 Data – removal, inspection or insertion of data onto a network for malicious or profitable
motives
 Internal – abuse of access to operator data by an employee for malicious or profitable
motives
 Interconnection – exploitation of operator interconnection agreements for malicious or
profitable motives
 Roaming – exploitation of operator roaming agreements for malicious or profitable
motives
 Technical – use of counterfeiting or other technologies to duplicate, infiltrate or manipulate
a mobile network for malicious or profitable motives

6. THE CHALLENGE
 The ‘natural’ order of tasks for revenue assurance is to:
 monitor for evidence of loss
 investigate where & why there is loss
 resolve the problems so loss does not occur again
 However changing nature of business relationships means
 not clear where boundaries lie & hence where operational risk may arise
 process design & data integrity becomes even more important

8. TECHNIQUES FOR AUDITING
Track-Back Approach The Grid Approach
 Audit works backwards from a  The key mobile revenue streams &
convenient point, such as the logical operations for each stream
customer invoice, to the first source are identified and set out in a grid
of data capture (e.g. voice, sms, interconnect streams versus
switch, mediation, rating, invoicing operations)
 Allows the detail of how the data
flows & is manipulated to be  Offers a useful visual framework to
help identify common processes &

leakage risks quantified how the processes work, the controls
and checks, known leakages and the
 Can be a time consuming process confidence that all leakages / fraud
risks have been identified
 The issue is that this approach may
not capture sufficient detail nor show
the commonality of operations
between revenue streams
