Designed to be the cornerstone of a convergent charging solution, HP OpenCall Service Access Controller brings together prepaid and postpaid voice and data services through a flexible architecture that allows service providers to roll out innovative payment solutions in a timely fashion.
HP OpenCall Service Access Controller integrates with leading billing vendors' online charging systems and implements the Intelligent Network (IN) model as well as standardized IP protocols (SIP, Diameter) to provide real-time control of users' voice and video calls, data sessions or content. This puts service providers in a position to control usage in real-time, virtually eliminate prepay revenue leakage and deploy new revenue-generating services to all customers.
Key benefits
HP OpenCall's convergent prepaid-postpaid solutions combine the efficiency of the IN model with the flexibility of billing systems' rating engines and account management features. HP OpenCall SAC integrates with these vendors' charging systems so that the same rating engines can be used for prepaid and postpaid usage, and a single balance management function can be used.
Total cost-of-ownership can be reduced, through the implementation of a single stream of support systems for prepaid and postpaid subscribers alike.
Flexibility to offer new service offerings, leveraging a single service catalog or combining different payment modes for different services under a single account.
Key features
The HP OpenCall Service Access Controller builds on the strengths of the proven IN model for prepaid support. This model is established as the most robust and scalable way of delivering latency-free service access to users, while removing the revenue leakage other models are susceptible to.
The single balance management system enables advanced account structures and top-up scenarios, and simplifies provisioning for enhanced service offerings and flexible payment options for your subscribers.
Open, flexible service control point (SCP) provides maximum connectivity to GSM, ANSI and 3G networks, and service logic can be adapted as part of a deployment project to fit specific scenarios.
Additional services can be developed together with existing service logic. This enables the deployment of enriched value-added services combining charging options.
Security in deployment and operation with HP's worldwide delivery and 24/7 support services that meet the stringent requirements of mission-critical telecom processes, such as online charging call handling.
