NRTRDE Support Subsystem
Entry for registered users

NRTRDE Support Subsystem

NRTRDE (Near Real Time Roaming Data Exchange) is a new technology purpose-designed to help telecommunications companies decrease revenue losses caused by roaming fraud. GSM Association strongly recommends to extend current roaming contracts by adding a clause concerning NRTRDE support from October 1, 2008. Therefore, starting from this date, it would be more convenient to cooperate with companies supporting this technology. According to Fraud Forum’s opinion, working with a reliable partner using NRTRDE may lead to roaming traffic and revenue increase, which is actually inevitable as:

  • Telecoms will encourage their subscribers to call more while roaming in the networks of partners supporting NRTRDE
  • Telecoms will allow much more customers to use roaming in the networks of partners supporting NRTRDE.

System Operation

According to Fraud Forum's estimates, NRTRDE provides 90% reduction in losses from roaming fraud and saves hundreds of thousands of dollars annually. The new technology is substituting for High Usage Report (HUR), an out-of-date and ineffective technology requiring to send roaming call data to partners not less than once each 4 hours. For comparison, modern GSM Association's rules set this periodicity to once per 5-15 minutes. Timely received roaming call data can be timely analyzed by roaming partners to detect and eliminate fraud before it could affect revenues.

Key Features

CBOSSnrtrdeOut – Sender Side:: Generation of NRTRDE files

  • Generation of NRTRDE files
    The system automatically processes files from the switch, identifying call detail records for each roaming partner that has agreed to exchange NRTRDE files.
    NRTRDE files are then sent to the partners. The sending frequency can be set individually for each partner.
    It is possible to filter CDRs by various parameters in accordance with the roaming partnet agreement.
  • Delivery reports
    The system supports notifications of NRTRDE file delivery (NRTRDE file delivery report).
    The system can also import the delivery failure reports (NRTRDE error report) to the analytical system to analyze the reasons for rejection and re-generation of records with errors.
  • Statistics
    The system supports collection of statistics related to the current system status or executed operations with NRTRDE files.
  • Scalability
    The system supports horizontal scalability
  • Independent uninterruptible 24х7 operation
    The system is tolerant to the patchset running and can function without access to the database.

CBOSSnrtrdeIn – Receiver Side:: Downloading of NRTRDE files

  • Downloading of NRTRDE files
    The system automatically downloads NRTRDE files, saving the processing results to the database for further analysis and control over the observance of the roaming agreements. The analysis and control are provided by the reporting system.
  • Validation of NRTRDE files
    All downloaded NRTRDE files are validated in accordance with TD.35. The validation results in the generation of the NRTRDE file delivery report and NRTRDE error report that are then sent to the partner.
  • Independent uninterruptible 24х7 operation
    The system is tolerant to the patchset running and can function without access to the database.

CBOSSnrtrdeInPrecharge – Receiver Side:: Roaming fraud control

  • Fraud control
    CBOSSnrtrdeInPrecharge automatically downloads NRTRDE files and sends the records to the rating system. The rating system generates preliminary charges and changes the subscriber fuzzy balance, preventing debts.
  • Control over unjustified disconnection of customers
    When TAP files are received, the system finds corresponding call detail records in the NRTRDE file received before. When the record is found, CBOSSnrtrdeInPrecharge notifies the rating system that removes preliminary charges and generates real charges.
  • Notification of prepaid platform
    If necessary, information on creation or deletion of preliminary charges can be delivered to the prepaid platform to provide timely control of the subscriber account balance.

CBOSSnrtrdeInSplit – Receiver-Distributor Side:: Transit of NRTRDE files

  • Distribution of incoming NRTRDE files
    The system automatically downloads NRTRDE files and separates records belonging to local exchange carriers (LECs) and interexchange carriers (IXCs).
  • Independent uninterruptible 24х7 operation
    The system is tolerant to the patchset running and can function without access to the database.

Benefits

  • Storage of statistics
    The system saves all the information on the progress and results of NRTRDE file downloading and generation, which allows the collection of any statistical information anytime.
  • Independency
    The system operates automatically, providing fraud control without human assistance. In case of emergencies, the system automatically restores without loss of information and does not sent duplicated records to roaming partners.
  • Integration with CBOSSbcc
    The system is seamlessly integrated with CBOSSbcc, which, coupled with timely delivery of NRTRDE files, guarantees maximum reduction of losses caused by roaming fraud. The above-mentioned functionality of preliminary charge generation can be set up in any possible way to provide both efficient fraud control and prevention of unjustified disconnection of subscribers.
