Diameter Signalling Controller

As data traffic increases, we help operators to optimize and scale signalling protocol requirements across today’s next generation networks.

In today’s LTE and IMS networks, Diameter Signalling replaces legacy signalling protocols for mobility and charging control with a single flexible protocol. The convergence to a single signalling protocol may simplify the signalling landscape, but it does not reduce the complexity of the signalling flows between the network elements.

With new LTE networks going live every month and with LTE set to replace legacy networks in the coming years, Diameter has assumed a pivotal role as a signalling protocol. As a consequence, Diameter Signalling traffic today is outpacing the originally predicted growth, which is creating new bottlenecks and signalling management pain points across the networks.

Our signalling control solutions are designed to meet today’s network evolution challenges, and our Diameter Signalling Controller can be deployed to ensure Diameter signalling is optimized to scale across networks as they evolve.

The Diameter Signalling Controller (DSC) is used to manage network scalability, protocol interworking, traffic management, load balancing, intelligent traffic routing and appropriate charging mediation for data services.

The Enghouse Networks DSC is network equipment vendor agnostic and complies with relevant 3GPP and IETF standard specifications and serves as a Diameter signalling aggregation point, thereby reducing network congestion. A Diameter Gateway enables translation between various protocols such as Diameter, XML, MAP, CAMEL and other protocols that may be used to achieve interoperability between 2G/3G and LTE networks and more in general between signalling nodes that use different protocols.

Enghouse Networks Diameter Signalling Controller can perform all, or any combination of, the following Diameter Signalling Control and Management functions:

Diameter Load Balancer (DLB)

Avoids unnecessary network expansions by optimizing your network resources with sophisticated load-balancing algorithms, to distribute Diameter traffic across them with maximum efficiency

Diameter Gateway (IWF)

Interworking Function (IWF) ensures the continuity of roaming revenues as subscribers roam between LTE and legacy networks

Diameter Edge Agent (DEA)

Shields and protects your core network nodes from direct interconnection with external links, and ensures the continuity of roaming venues by filtering and normalizing Diameter traffic crossing your network border

Diameter Routing Agent (DRA)

Reduces the time required for maintenance and testing by simplifying and controlling Diameter routing in your network
