Fraud is a growing concern in the telecommunication industry. Operators are

losing billions of revenue each year due to telecommunication fraud.

Roaming Fraud in particular has contributed 24% of overall

telecommunication fraud worldwide according to a report done by GSMA

back in 2008. And since then this number has increased and has affected

many operators.

Fraud techniques have become more sophisticated, which has rendered

methods such as High Usage Reports (HUR) obsolete. As a response,

GSMA released a mandate that all operators must stop using HUR and start

implementing NRTRDE by October 1, 2012.

Near Real Time Roaming Data Exchange (NRTRDE) is a procedure that

allows operators to efficiently exchange roaming data with their roaming

partners. This will enable HPMN to monitor roaming call records in near real

time and have an active role in preventing fraud.

EDCH offers a complete solution in implementing NRTRDE. We will facilitate

the exchange of NRTRDE data between you and your roaming partner, while

you focus your attention in addressing fraud. We also provide raw data

conversion, customized notifications and specialized reports that will help

your transition from HUR to NRTRDE.

1. INTRODUCTION

Many operators have at some point encountered an incident regarding roaming

fraud. And each occurrence is an expense that quickly accumulates to become a

serious opportunity loss.

Organized fraud groups have made a business out of roaming fraud. For instance, it is

easy for anyone to illegally acquire an international postpaid subscription and make

fraudulent calls to numbers with high termination costs without the intention to pay.

These calls can then be routed to international carriers through an audio text service

provider and revenue from these calls is shared with the fraudulent caller. Fraudsters

maximize their illicit gains by making high volume calls before calls are detected and

suspended by the HPMN. By the time the calls are suspended, the fraudster would have

already made a large profit at the expense of the HPMN.

Figure 1: NRTRDE sends data faster and more efficient than HUR.

GSMA has deemed HUR ineffective in preventing modern methods of roaming fraud.

This the reason why HUR is no longer supported by GSMA as of October 1, 2012.

Near Real Time Roaming Data Exchange (NRTRDE) is a procedure that allows

operators to efficiently exchange roaming data with their roaming partners. This will

enable HPMN to monitor roaming call records in near real time and have an active role in

preventing fraud.
