Fair Isaac and Optel Informatik announced the mobile industry's first Near Real-Time Roaming Data Exchange (NRTRDE) gateway to help wireless operators worldwide prevent roaming fraud

The NRTRDE gateway connects Fair Isaac's RoamEx^® Roamer Data Exchanger network to Optel's MEGS-R network, enabling an automatic, two-way exchange of roaming traffic in near real time. The resulting combined coverage forms the world's largest NRTRDE network, with more than 90 mobile operator networks involved.

Roaming fraud accounts for a high proportion of all fraud in telecommunications. It occurs when a mobile phone subscriber who does not intend to pay for service roams from the service provider's network to another operator network and takes advantage of the home operator's delayed access to the subscriber's call detail records while roaming. An individual roaming fraud incident can result in a loss of more than €1 million (US$ 1.3 million) within a matter of a few days.

As the trade association for the world's leading global mobile standard with more than two billion subscribers, the GSM Association has recognized this problem and has decided to pursue NRTRDE adoption by all GSM operators by October 2008.

By linking their RoamEx and MEGS-R systems, Fair Isaac and Optel can offer unsurpassed roaming call visibility to operators who subscribe to either network. Operators connected to either RoamEx or the MEGS-R system automatically receive call records for their roaming subscribers from anywhere in the combined network, greatly reducing their roaming fraud exposure.

"The combination of RoamEx coverage in the Americas with Optel's EMEA coverage aligns well with our goal to provide customers with global NRTRDE coverage," said James Stewart, associate partner of client services, Telecom, for Fair Isaac, who also chairs the Roaming Subgroup of the GSMA Fraud Forum. "As more operators look to follow the GSMA's NRTRDE initiative, they will require a NRTRDE solution that provides them with maximum coverage. A roaming fraud solution is only as good as the coverage provided, because it can only detect roaming fraud in operator networks where it has been deployed."

"We are proud to take another milestone in the fight against roaming fraud," added Markus Dicks, Managing Director of Optel Informatik. "With this connection of the two largest NRTRDE networks, we can offer our customers much higher fraud visibility and that is what counts. This advantage will be available for customers on both sides of the network, and linking them together boosts the CDR data exchange volume dramatically."

Fair Isaac's RoamEx solution serves over 70 operators including 95 percent of the Americas market, while Optel's MEGS-R solution serves major operators, including T-Mobile, in Europe. By linking these two systems, Optel and Fair Isaac can offer unsurpassed roaming call visibility to operators who subscribe to either system.
