NT NRTRDE arms you with a powerful weapon that can help reduce the risk of roaming fraud, protect your network investments, and safeguard the environment for the increasing number of roaming subscribers. It is a robust, innovative and cost-efficient Near Real-Time Roaming Data Exchange (NRTRDE) platform that provides immediate access to the critical information needed to combat roaming fraud.

How to tackle roaming fraud?

All GSM operators are urged to start preparation for implementing
their NRTRDE systems to keep final deadline.

Roaming FMS and Provisioning System Architecture

• Fraud traffic identified by defined condition and basically able to be configured.
• Manual provisioning is taking action by manually.
• Automatic provisioning is taking action by defined rule. Also able to exclude some traffic due to acceptable reason such as VIP number, etc.

Netwave-NRTRDE Implementation Scenarios

Alternative scenarios:

1. Via Network Element (Directly)
   • Standalone, parallel process with the mediation
   • Uses raw data from Network Element
   • Multiple address collection data source
   • Many Network Element source should be collected (difficult to maintain)
2. Via Mediation
   • Single address collection data source.
   • Independent solution, separate from TAP process
3. Via Tap
   • Dependent to existing roaming management system
   • Result available following billing cycle

Netwave-NRTRDE Modules Architecture

Netwave-NRTRDE Module Architecture

• Converter

Convert some different format input files into NRTRDE file or FMS format

• Filter

Selection input file for only roaming transaction record

• Normalization

Refine some record to have correct value to accepted

• Generator Module

Generate input file into NRTRDE format (VPMN) or FMS format (HPMN)

• Distributor Module

Transferring file via ftp or http protocol

• Validation

Validate filename, syntax, column sequence as define

• Roaming Fraud Management System

Identify any suspect fraud traffic by defined rule as follows:

-          Long duration call

-          Hyperactive call

-          Restricted area

-          Other configurable feature.

• Provisioning System

-          Blocking MSISDN customer directly to HLR or via Provisioning Mediation

-          Divided by process manually and automatic.

Netwave-NRTRDE Interfaces and Compatibilities

• Support various type of Input Formats :

ASN.1, Fixed Length Binary, XML, CSV, ASCII, TAP Format, NRTRDE

• Support various interface of Network Elements :

Netwave-NRTRDE Report Management

Report Management consists of

• Standard Reports.

• Interesting analytical reports.

Issues and Solutions

• Different Time Zone in Indonesia

• NRTRDE CDR need time deviation info refer to GMT

• No info time deviation in CDR MSC
  • Time deviation calculated from MSC Location

• Different GMT Deviation

• Delay detection for HPMN
  • Convertion into local time

• Elapse Time max 4 hours

• Calculating end to end NRTRDE process
  • Netwave-NRTRDE elapse time about 1 (one) hour

• Data Retention

• Raw Data = 1 week

• CDR NRTRDE (file, database) = 3 months

Netwave-NRTRDE Benefits and Advantages

• Open and fully configurable for input interface :

• ASN.1 format

• ASCII delimited format

• Binary fixed format

• TAP File

• NRTRDE format file

• Flexible interface for output format to Fraud Management System.
• Fully automated processing of NRTRDE files, generate delivery and error reports.
• Notification of technical problem to administrator and roaming partner by email or sms.
• Simple and quick on site deployment.
• Configurable workflow for each different roaming partner.
• Adaptive for multi time zone data.
• Complete report for NRTRDE process monitoring
• And additional interesting analytical report.
