Ericsson Diameter Signaling Controller

The growing volume of Diameter signaling is driven by the deployment of LTE networks and policy control solutions, and will further increase with the introduction of voice of LTE. The Ericsson Diameter Signaling Controller protects service reliability at times with very high signaling load and prevents signaling storms in case of node failures and malicious security attacks. The Ericsson Diameter Signaling Controller can be deployed as a native or virtual node and is fully integrated with Ericsson's network management system.

 

Versatile functionality and scalable capacity

The Ericsson Diameter Signaling Controller meets the high requirements demanded by control signaling products in terms of in-service performance and scalability, and can be used as:

  • Diameter Agent – routing of signaling messages between nodes in a network, i.e. an aggregation and policing point reducing costs and providing an end-to-end view
  • Diameter Edge Agent – routing of signaling messages between networks of roaming partners and improving network security by collecting and presenting security-related information including a fully integrated signaling firefall
  • Diameter Routing Agent – routing of signaling messages for policy control and charging, i.e. ensuring that the load is evenly distributed and that messages pertaining to a specific session are routed to the same server node
  • Unified Signaling Firewall - Protecting the network from malicious diameter signals. Support for stateful cat.3 SS7 is also available starting from Q3'18.

The Ericsson Diameter Signaling Controller can also redirect signaling based on indications from other signaling end points or instruct them to redirect their signaling messages. Furthermore, the node provides backward compatibility in terms of interworking and translation between Diameter protocols and legacy signaling protocols used by nodes such as Equipment Identity Registers and Home Location Registers.

The full functionality of the Ericsson Diameter Signaling Controller is available no matter if the native or virtual implementation is chosen and the capacity of the node is scalable from 2500 to millions of messages per seconds.

Certified integration and support consultants

The Ericsson Diameter Signaling Controller is complemented with a range of Ericsson services, which are delivered by certified consultants with long experience from systems integration and technical support. This caters for a truly future-proof Diameter signaling network that can be deployed without disturbances and evolve towards a unified signaling architecture for all network elements.

Customer references

The Ericsson Diameter Signaling Controller has been sold to more than 90 operators in just five years' time and is used in commercial operation both as a native and virtual node. The capabilities and performance of the product, coupled with Ericsson's end-to-end understanding of telecom networks and long-term commitment to support and further develop signaling products, have made Ericsson the fastest growing signaling vendor in the market.
