According to a recent GSM Association (GSMA)survey of 37 operators, significant roaming fraud losses affect networksof all sizes and in all regions. In one instance, a single operator is reportedto have suffered losses of €11.1 million in less than two years.“Today’s networks were originally equipped to prevent such losses, but inevitably, roaming fraudhas become more sophisticated and can now overcome recent anti-fraud measures,” said EugeneBergen Henegouwen, Executive Vice President, EMEA, Syniverse. “As a result, the GSMA has takendecisive action by implementing Near Real Time Roaming Data Exchange (NRTRDE), a new standardthat will dramatically improve the ability of operators to detect and act upon fraud.”According to the GSMA, as operators adopt NRTRDE, they are expected to be able to reducethe incidence of roaming fraud by up to 90 percent.
7GSMA Cont. from page 6A New Way to Combat Roaming FraudOperators today rely on a High Usage Report (HUR) to alert them to possible instances offraud. This framework requires the transfer of a call data record (CDR) detailing roaming serviceusage between the visited (roaming) and home operator networks within a 36-hour window. In manycases, the record arrives too late to prevent the fraud, and the defrauded revenue is lost for good.The NRTRDE standard will replace HURs. With NRTRDE, the visited network is requiredto forward CDRs to the customer’s home operator within four hours of the call end time. If thevisited operator is unable to get this information to the home operator in time, the visited operatoris held liable for any fraud associated with those calls.Eugene said the benefits of implementing NRTRDE are enormous. “Not only does NRTRDEreduce the potential revenue lost to roaming fraud and increase an operator’s profitability, it also offersa secure environment for subscribers and gives confidence to operators that their networks arecombating fraud more effectively,” he said. “Ultimately, it will increase profitability through a newproactive, robust response to organized crime.”Cont. on page 10of the NRTRDE InterworkingGroup, which seeksto ensure interoperabilityamong NRTRDE vendors.Christer also is theofficial author and editorof many GSMA permanentreference documents,including TD.35 (NRTRDEFormat Specification)and BA.08 (Timescales forData Transfer) – both keyNRTDRE documents. Herecently was recognizedby the GSMA’s ExecutiveManagement CommitteeChairman Stein Hansen andCTO Alex Sinclair as a keycontributor to the organization’sNRTRDE initiative.“It has been an honorto have been part of theGSMA’s NRTRDE initiativesince the beginning of theproject in 2006,” he said.“The collaboration that’soccurring among industryexperts in fraud management,roaming and technologyis very rewarding, andI think the roaming fraudsolutions that result fromthe GSMA’s work will makea significant difference tothe future of operators whochoose to fully implementthe new standards.”
