DOCOMO PACIFIC Selects Helix to Enable 4G Roaming

Read the Release


The BorderNet Diameter Services Helix 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 BorderNet Helix empowers 3G, 4G, fixed and Wi-Fi operators 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 BorderNet™ Diameter Services Helix, the next generation of Diameter Signaling Controllers, 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 Helix 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

The Helix supports both DRA and DEA functionality along with unrestricted access to the payload of any inbound message for exceptional routing control. The Helix 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

The Helix 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 service providers 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 BorderNet™ Diameter Services Helix provides a rich set of ready-made templates for the most common Diameter applications and allows for easy addition new interfaces, protocol variants, and proprietary extensions.

MVNOs Take Control

Discover how the Helix puts the control into the hands of mobile virtual network operators, aggregators and enablers of their network, services and customers to help accelerate time-to-market and differentiate their offerings from those of their underlying mobile network operators (MNOs).

Tackling Vendor Interoperability Challenges with Less Downtime


Find out how the Helix helps service providers accelerate time-to-revenue with the ability to easily fix incompatibility issues between vendor platforms without the need for costly and time consuming development work.






Multi-protocol interworking and service orchestration through integrated Web 2.0 GUI

Provides the ability to apply advanced logic to protocol message flows.  Diameter and non-Diameter services can be intelligently routed based on protocol, message parameter or message context, resulting in rapid development of new services for fast time to market.

Integrated Diameter Routing, Edge agent and Interworking function on a single unified platform

Provides centralized management, security, load balancing and multi-protocol, multi-domain interworking and orchestration for faster network and service deployment.

Multi-protocol support with extensibility to add additional protocols and protocol variants

Removes the need for expensive and time consuming development to support new protocol variants or complex interworking use cases.

Real-time dashboard and extensive reporting and analytics Real-time visibility into system performance and reporting on each protocol along with detailed recording of protocol events, configuration auditing, logging and tracing provides valuable intelligence to improve operational efficiency.
