Explaining the Role of PCRF & PCF in Modern Networks
In today’s telecom landscape, user expectations are higher than ever. Real-time connectivity, seamless experiences across services, and smart data usage policies are no longer a luxury — they are a necessity. This is where Policy and Charging Rules Function (PCRF) and Policy Control Function (PCF) step in, playing a critical role in network intelligence and flexibility.
From PCRF to PCF: The Evolution
Traditionally, the PCRF has been the cornerstone of 4G networks. It enables dynamic control of services, managing QoS (Quality of Service), charging rules, and access policies for both voice and data. As 5G networks emerge, the PCF takes this a step further, becoming the native policy control function in 5G Core architectures.
But not all operators can transition overnight to 5G. That's why at Summa Networks, we’ve developed a modular, future-proof solution that supports operators at every stage of their evolution.
Summa Networks' Policy Function: Modular and Multi-Generational
Our Policy Function is fully 3GPP-compliant and telecom-certified, providing:
- Voice PCRF: Ideal for operators focusing on VoLTE or VoWiFi services, offering voice-specific policy control and simplified architecture.
- Full Voice and Data PCRF: Extends policy control to both voice and data services across 3G, 4G, and 5G NSA networks.
- Combo PCF: A dual-mode solution that supports both 4G and 5G SA deployments — perfect for operators in transition.
All components can work as standalone products or be integrated into our Full Core, giving operators complete flexibility and control over how they evolve their networks.
Why It Matters
- Interworking is key: Our solutions support multi-generation and multi-vendor environments, allowing operators to maintain existing investments while preparing for the future.
- Self-paced evolution: You decide when and how to upgrade — no forced timelines or vendor lock-in.
- Future-proof: Whether you’re managing legacy networks or deploying cutting-edge 5G services, we provide a path that evolves with you.
Empowering Operators with Intelligent Policy Control
As networks become more complex and user demands more sophisticated, having a robust, adaptable policy control solution is no longer optional — it's strategic. Whether you're operating in 4G, preparing for 5G, or navigating both, Summa Networks’ Policy Function gives you the tools to define, prioritize, and monetize your services with agility and confidence.
Our mission is simple: to support operators worldwide with a modular, intelligent, and future-ready core — because your network should evolve on your terms.
