The Dialogic® Helix™ Signaling Controller (HSC) is a platform built for innovation. It is a next generation Diameter Signaling Controller (DSC) with an advanced service orchestration framework that provides Interworking Function (IWF), Diameter Edge Agent (DEA), and Diameter Routing Agent (DRA) functionality in a single unified solution. The HSC empowers 3G, 4G, fixed and Wi-Fi Communications Service Providers (CSPs) with support for:

  • Seamless service creation and multiprotocol interworking
  • Secure and scalable any-to-any service connectivity
  • Increased velocity in bringing networks and services to market


The Dialogic® Helix™ Signaling Controller combines DEA, IWF and DRA functionality to provide intuitive service enhancement and orchestration capabilities for mobile, Wi-Fi, IPX and fixed operators.


Take Interworking of Diameter, RADIUS and SS7 to the Next Level

The advanced service orchestration bus and template driven architecture enable rapid service creation and service enhancement while providing unmatched ease of use and flexibility compared to other interworking (IWF) approaches on the market today.  The HSC makes it possible to perform multi-protocol interworking on Diameter, RADIUS, SS7, and HTTP along with other IT protocols through an intuitive Web 2.0 based GUI to help eliminate the need for stand-alone gateways.

Secure 3G and 4G Mobile Core Assets

HSC supports both DRA and DEA functionality along with unrestricted access to the payload of any inbound message providing CSPs exceptional routing control. HSC supports GSMA IR.88 DEA specifications making it well suited for mobile and IPX networks with features like:
  •  Dynamic Routing
  • Overload Protection
  •  Diameter Mediation
  •  Load Balancing
  •  Topology Hiding
  •  Diameter, RADIUS and MAP Interworking
  •  PCRF and HSS Binding
  •  Subscriber Lookup Function
  •  GUI-based Flow Management





Centralize Management and Routing of Diameter Messages

HSC can help you address the explosion of Diameter traffic and reduce the complexity of managing connectivity between diverse network nodes with an RFC 6733 compliant platform. The template driven architecture enables CSPs to easily add additional Diameter interfaces and proprietary extensions without the need for vendor intervention giving you more control over how they manage your networks.  Integrated IWF functionality provides additional flexibility to extend interoperability of services across legacy and Wi-Fi networks.



The Dialogic® Helix™ Signaling Controller can support any Diameter interface and provides a rich set of ready-made templates for the most common Diameter applications. HSC allows for easy addition new interfaces, protocol variants, and proprietary extensions.
