Roaming fraud is a serious global concern for mobile operators. Nowadays combating and preventing losses caused by roamers' fraudulent behaviour represents a hot topic in mobile industry discussions. The GSMA community has worked out the best solution to combat roaming fraud: NRTRDE (Near Real Time Roaming Data Exchange). The implementation of the NRTRDE as mandatory system for all GSMA members shall be done by 1 October 2008. Operators may implement NRTRDE in advance of this deadline through bilateral agreements.

Operators and vendors have already started some preparations. Different implementation strategies, solutions and architectures have to be considered very carefully from several aspects.
