In today’s dynamic telecom landscape, mobile network operators (MNOs) and MVNOs face the challenge of catering to a wide spectrum of user demands, from high-usage subscribers requiring unlimited plans to low-usage customers preferring extended validity and simple usage-based pricing.
The prepaid billing system offered through Primal Technologies’ OCS/PCRF platform is designed to meet these diverse needs with precision, flexibility, and cost-efficiency. This system enables operators to deploy monthly, weekly, daily, and usage-based plans with real-time rating and charging capabilities.
How is it different from the postpaid billing system?
Unlike traditional postpaid models,
the prepaid billing system ensures lower operational costs by
automating subscription management, top-ups, and billing
cycles electronically. It also supports bucket-based add-ons
for voice, SMS, MMS, and data, which can be activated via
USSD, SMS, IVR, or web-based self-care portals.
The architecture is built to accommodate granular zone-based
rating, dynamic bucket creation, and automatic periodic
charges, all of which enhance marketing agility and subscriber
satisfaction. Moreover, the system integrates seamlessly with
various network interfaces such as CAMEL, DIAMETER Gy, Sy, and
Ro, enabling robust control over call and data sessions. For
5G standalone deployments, the platform includes a
containerized CHF supporting the Nchf interface, ensuring
future-proof scalability. Operators benefit from full PCI
compliance for secure credit card top-ups, flexible
voucher/card usage, and XML-based provisioning for subscriber
lifecycle management.
The system also supports tiered policy control and
traffic-type policy enforcement, allowing for intelligent data
throttling and restoration based on spending thresholds. This
comprehensive solution empowers operators to maintain
competitive voice, messaging, and data packages while
optimizing cost structures and enhancing user experience.
