• Proven legal & regulatory compliance
• Effective testing, supporting service and tariff development - 90% of traffic cases tested
• Automated execution and higher testing efficiency - 80% less resources needed
• Shorten Time to Revenue - invoice testing period reduced by 70%
• Increased subscriber satisfaction
• Extremely frequent (even daily) execution in contrast to a project based approach
• Seamless evolution from project to process based approach

Furthermore, the project enabled Magyar Telekom to operate, further develop and extend a pro-active process in order to continuously assure maximum revenue and efficiency.

The great achievement of the innovative approach is that revenue assurance has lost its event-driven character and become an efficient, repeatable, daily routine. The process-based approach ensures that even the smallest problem is detected in time. Thanks to the continuous control, the aggregation of problems and domino effects are avoided. Revenue leakages are identified and solved efficiently.

A common problem regarding billing system testing, validation and auditing is that the coverage is not sufficient. And increasing it requires enormous resources and reusability is not solved. Problems are mainly concentrated in the execution and evaluation phase: test execution is never perfect. Failed and repeated calls, imperfect timing and unsatisfactory call identification make testing both a difficult and involved task. All the problems noted at test execution roll over to evaluation. As a whole, there are two critical points: the production of test data and the evaluation of the results. Neither of them has been fully automated previously.

A fashionable methodology is coming into play and provides the solution for the problems above: stability testing



Stability testing for call detail record processing is based on a representative test record set that is created and submitted to the billing system for each test run. The evaluation is the comparison of the recent and previous results. Only the differences are investigated - errors are corrected, foreseen changes are approved and reference results are updated. Therefore maximum efficiency of test evaluation is assured.

Summing up, operators have to prove the accuracy of their systems. But the methods and tools applied must be at least as reliable as the system itself. Therefore, it is a huge responsibility and challenge for suppliers of billing support systems to prove the compliance of their products and services. This objective is supported by the BABT attested CeDaR ensuring the acceptance of CeDaR-based testing and auditing processes by regulatory bodies and other authorities worldwide.
