NexusVERIFIER TCG is currently integrated with Mobilink's network system. CDRs from both the TCG and the billing records from the network elements are available to the reconciliation system.
Ch. Abdul Mannan explained, "The use of the NexusVERIFIER TCG is a great success and we are taking advantage of it in a number of areas:
- Product Pre- and Post-launch testing (Behavior and charging)
- Testing for Post-paid and Pre-paid Products
- TCG Results Reconciliation with various (OSS/BSS) platforms
- Network and service quality testing
- Account Rounding issues at different levels
For us, this has become a measuring tool for different Revenue Assurance and Fraud Management KPIs to know the completeness and accuracy level of different CDR data sources/systems."
The Revenue department was able to test both Pre-/Post-paid subscriptions, comparing fields including duration, MOC/MOT cell location, time slot of the day, customer classification SIM card, short code dialing, specific behavior patterns for tariff plans, and many more.
Mobilink's tariff service launch from concept idea stage to a commercial launch was easy on paper, but when an innovative concept is introduced to a live network, a lot can change. Therefore, NexusVERIFIER TCG was used to test the new concept without impacting the live subscribers. To cover all the many customer segments within Mobilink, the NexusVERIFIER TCG was loaded with large pool Subscriber SIM Cards that could be used in parallel for tests.
Nexus VERIFIER TCG was also used to perform and identify fraudulent scenarios. e.g. when calls dialed with local prefixes were routed internationally, but charged as domestic.
Nationally, intersystem/network timing differences were analyzed using the CDR time stamps, which is important for charging, and to ensure that all nodes are configured to be synchronized to one clock source.
Some new services or ideas were test launched for the particular targeted geographic location. NexusVERFIER TCG allows users to perform testing in any cell coverage location, including intersystem/network nodes duration testing.
