Scaling the Mobile Control Plane

There’s a lot of industry focus on escalating data traffic. It’s definitely challenging, but Diameter signaling can create even bigger problems. It’s growing 30 to 50 percent faster than data traffic. The biggest culprit? Signaling chatter between control-plane elements like policy servers, subscriber databases and charging systems.

If you build your IP network without a signaling core, it’s at risk. Diameter traffic will eventually overwhelm the limited routing capabilities of your control-plane devices.

With the New Diameter Network, you can get ahead of that growth curve. It’s designed to handle massive data and signaling loads.

The key components include:

• Diameter Signaling Router (DSR): ensures subscriber databases, policy and charging functions and subscriber databases can scale, balances the signaling load and reduces congestion, enables service portability and roaming, and ensures security
• Policy Server (PCRF): sets the rules for managing network resources and prioritizing subscribers, applications and devices. The key to quality of experience.
• User Data Repository (UDR): the key to unlocking value, personalizing services, improving customer loyalty
• Policy Analytics: Monitors effectiveness of Diameter traffic management, policies on subscriber experience and network resources

• Create an elastic Diameter network architected for adaptability and scalability
• Roll out new services quickly – in days or weeks, not months
• Deliver always-on, five-nines reliability
• Optimize traffic management and service portability across multiple access networks
• Pay as you grow: Scale your Diameter network incrementally to support increasing service and traffic demands
