Inter carrier settlement solution
 
 
The client
A leading Indian mobile operator offering local, long distance and international voice and data services to a large subscriber base.
 
The challenge
The customer wanted to reconcile CDRs and bills with PTT for all its local, long distance and international calls. But there were consistent discrepancies in the interconnect invoices due to differences in the mediation and rating rules of PTT and our customer. The difference in the invoice amount would typically be to the tune of 7-8%. The challenge for Wipro was to reconcile these differences and hence arrest the potential revenue loss that the customer was suffering. Wipro’s solution needed to import soft copies of the invoices from the PTT into the interconnect system and thereby reconcile with the invoices generated by the service provider’s billing system.
 
The solution
Wipro employed the following methodology to resolve the reconciliation challenge faced by the client.
A comprehensive study and analysis of the differences in the mediation and rating rules. It helped identify the various business rules that are to be configured in the interconnect module
Development of tools for automated reconciliation based on the business rules identified at the earlier stage
Finally, institutionalization of the interconnect reconciliation process in the customer’s organization

Wipro put the above mentioned framework in place by design and implementation of an interconnect module that was integrated with the billing system. This system helped the client in importing the PTT invoices and identifying discrepancies with its own invoices. Wipro’s solution also helped in generating MIS reports that would highlight these discrepancies so that necessary action can be taken at the earliest.

In addition to this automated solution, Wipro also provided the client with a comprehensive analysis of the discrepancies; it helped the client identify root causes for the discrepancies and hence take corrective actions wherever possible. The Wipro team was also responsible for tracking and resolving the disputes related to the client’s interconnect reconciliation.
