Dialogic BorderNet Diameter Services Helix which was named Finalist in the LTE Asia Awards in the category of Best LTE Core Network Product represents the next generation of Diameter Signaling Controllers (DSCs). It is a carrier class integrated solution that provides rapid service innovation and signaling orchestration across mobile, IPX, Wi-Fi, IMS and fixed networks. The BorderNet Helix seamlessly combines multiprotocol interworking, Diameter Edge Agent (DEA) and Diameter Routing Agent (DRA) features in an integrated, easy-to-use platform that can extend the capabilities of existing Diameter routing solutions and expands the possible use cases past what is supported by the current generation DSCs.Helix supports interworking scenarios involving Diameter, RAIDIUS and SS7 along with real-time, customized service enhancement logic for rapid integration with external subscriber and policy data repositories via LDAP, SOAP, XML and HTML.

9. Signaling Controller for Service Enhancement and
Creation
• Deployment flexibility
• Reduces lengthy and costly development cycles
• Lowers CAPEX
• Accelerates time-to-revenue

Next Generation DSC’s Role
Service creation and enhancement
through real-time inspection and
application of logic to traffic
How this is done:
• Interworking signaling protocols
• RADIUS, MAP-Diameter
interworking
• Application of logic to message
content
• Inspection of subscriber, policy,
and charging intelligence
• Real-time reference of black-list
data to dynamically affect message
flows

Ability to translate
Diameter with non-
Diameter protocols,
actionable message flow
inspection, and
intelligence integration
from external data
repositories
• Alternative deployments
• Virtualized environments
• Decoupled functionality

12. Summary
Control plane signaling offers operators
opportunities to expand beyond standards
Differentiation
Flexibility
Service enhancement
Service velocity
Interworking provides the ability to take
back control and create service across
technologies
SDN, NFV and IP signaling have in a very
short period systematically redefined the
role of the control plane
The next-generation DSC will be the central
hub for services customization, agility and
innovation
