Replaced Legacy PCRF with OpenSource PCRF using Kamailio
“Being dependant on our legacy PCRF vendor’s R&D team to launch new services was expensive and time-consuming. CloudTern helped us to make a smooth transition to the open-source PCRF, enabling us to gain faster time to market and lower TCO. “
As a CPaaS provider, the company offers a complete development framework for real-time communications along with documentation and support throughout the product lifecycle. With the proliferation of smart mobile devices, unlimited broadband and virtual technologies, the demand for mobile internet services is increasing everywhere.
The Policy and Charging Rules Function server holds key to staying relevant in this dynamically changing communication environment. The PCRF server is critical in adding and configuring policies and managing Quality of Service (Q0S) for subscribers.
However, the company was using a legacy PCRF and is heavily dependent on developers at the vendor’s side to make changes to its solutions. It was expensive and time-consuming.
As the world is entering a 5G revolution, the company was looking for a cost-effective strategy to migrate the legacy PCRF to the cloud.
The company chose CloudTern as the systems integrator to replace its legacy PCRF with an open-source digital PCRF platform. DigitalRoute platform was chosen as the enterprise software for enabling billing based on subscriptions and usage.
CloudTern performed a detailed requirements analysis and designed the solution architecture with a 1:1 functional copy such that the same services were exactly implemented while other interfaces such as Deep Packet Inspection (DPI), Policy and Charging Enforcement Function (PCEF), provision notifications etc. are not impacted in any way.
Right from hardware and software delivery to policy rules implementation and integration with OSS/BSS, CloudTern ensured that the entire process was smooth and seamless. In addition, CloudTern developed other services based on the company’s offerings. The entire platform was designed in less than 6 months and the PCRF migration took less than a week.
