Billing & Charging System Testing Solutions
Billing & Charging systems record and process all usage data such as calls, SMS, and internet usage during specific billing periods, based on parameters like tariffs, commitments, discounts, and taxes. These systems categorize and report the cost components at the end of each period. It is crucial to differentiate between the charging and billing processes when assessing these systems. While the charging system operates in real-time during customer usage, the billing process is triggered at specific intervals based on operational rules.
To ensure the accurate operation of Billing & Charging systems in the telecommunications sector, two key data sources are required:
- Subscriber, product, and tariff data from CRM/sales order systems.
- Usage data collected from the network, known as Call Detail Records (CDRs).
Subscriber and product information triggered from CRM/OM systems are transmitted via web services to middleware systems and subsequently integrated into Billing & Charging systems. Similarly, data from the network layer is enriched and transformed into a format that IT applications can process, and then distributed accordingly. Mediation/Middleware systems manage this process, providing Billing & Charging systems with the critical CDR files necessary for pricing calculations.
Billing & Charging systems serve as the final touchpoints in the overall system architecture for completing end-user transactions. Once processes such as sales and installations are finalized, orders are transferred to the Billing & Charging systems. At Egemsoft, we offer end-to-end (E2E) testing solutions that encompass CRM/OM systems and Mediation and Middleware systems. We simulate operational processes in our test environments to ensure accurate and complete billing and charging activities.
As part of our testing scenarios, we conduct detailed testing activities, including creating appropriate subscriber sets, verifying the compatibility of billing and charging modules running on test servers, and executing test scenarios.
Errors in billing and charging systems can result in significant financial losses, which is why pre-implementation testing in test environments is critical before any system changes. These processes require detailed calculations and data preparation, making them a specialized area requiring expert knowledge.
