For most operators, Roaming is an important contributor to overall revenues, sometimes upwards of 30% in certain markets. Although a high-value revenue stream, Roaming is very often excluded from the traditional Revenue Assurance function, and there is no means to fully verify the integrity of inter-Operator billing processes. Some very simple checks and controls can provide the Revenue Assurance Manager and /or Roaming Manager with valuable insight into the invoicing and revenue collections process. Rating and Billing Validation for instance can be implemented in complete independence from the Data Clearing House (DCH) or Financial Clearing House (FCH) for invoice verification purposes. XINTEC strongly recommends a Roaming Health Check, which will provide beautifully simple answers to the following questions: - Are my inbound and outbound TAP and NRTRDE traffic feeds consistent? Am I missing traffic from my TAP feed that is present in the NRTRDE feed or vice versa? - Do my outbound TAP files contain all the inbound roamer traffic present on domestic switch elements? - Am I rating my outbound TAP files correctly thereby collecting the correct revenue from my Roaming Partners? - Am I rating my inbound TAP files correctly thereby collecting the correct revenue from my subscribers? - Are my agreed IOTs being applied correctly in my billing system and are the discounts being applied correctly? - Are my outbound partner invoices being correctly calculated? By integrating your roaming data feeds, invoices and IOTs into the RAevolution Revenue Assurance solution, the recommended XINTEC Roaming Health Check wilprovide answers and clarity to the above questions and enable full Operator access to the reports and results generated by the system.

1. Roaming Health Check
Assuring your Roaming Revenues

2. Key Operator Questions
• Is all Inbound traffic being invoiced to our Roaming
Partners? Are the right rates applied?
• Do we receive all TAP files for our Outbound traffic?
• Are all our TAP files for Outbound traffic processed in
our billing system at the correct rates?
The following slides show a sample report and an
output of a Roaming Health Check

3. The Solution
A focused Roaming Health Check that leverages
XINTEC RAevolution to provide checks and
controls on Roaming Revenue streams.

4. A comprehensive reporting capability
• Number of Records in TAP
• Number of Records in NRTRDE
• Matching Records
• Mismatching records on Duration
• Mismatching records on Monetary Value (IOT Validation)
• Mismatching records on Start Time (duration matching)
• Records missing from TAP
• Records missing from NRTRDE
TAP-NRTRDE Reports

5. • The results of the validations and reconciliations
are accessible online
• The reports and the underlying values can be
exported in many different formats
TAP-NRTRDE Reports

6. • NRTRDE vs TAP (All call types)
 Result: 88% average overall match
• NRT Voice Originating vs TAP Voice Originating
 Result: 86% average overall match
• NRT Voice Terminating vs TAP Voice Terminating
 Result: 87% average overall match
• NRT SMS Originating vs TAP SMS Originating
 Result: 87% average overall match
• NRT SMS Terminating vs TAP SMS terminating
 Result: 80% average overall match
Reconciliations Performed

7. • An average of 14-15% of mismatches on NRTRDE vs TAP for all
call types with Roaming data
• The major contributor of mismatches is Terminating SMS Call
Type (difference of ~135k TS records daily)
• Delays in TAP files arriving – to help overcome, re-run
reconciliations over the last 7 days, with results progressively
getting better over a period of time
• Mismatched investigated – Missing files/CDRs from certain
partners
• Consistent VPMNID’s missing TAP/NRTRDE files over time

Conclusion

20. RAevolution can also configure more complex reconciliations and
reports to include:
• IOT Validation – performing full re-rating of all inbound and
outbound roaming traffic using the agreed IOTs and
comparing the results with generated charges in TAP files
• Subscriber database reconciliation – reconciling
subscribers databases to ensure consistency in all
provisioned roaming services
