Signaling Controller for Service Enhancement and Creation

• Deployment flexibility

• Reduces lengthy and costly development cycles

• Lowers CAPEX

• Accelerates time-to-revenue

Signaling Orchestration framework Integrates routing, security, mediation, interworking, and enhancement

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


Importance of NFV to the DSC

Phase 1:Diameter relay message routing for scalability and survivability

Phase 3:Virtualization and orchestration of signaling controller capabilities

Phase 2:Orchestration framework: Ability to translate Diameter with non-Diameter protocols, actionable message flow inspection, and intelligence integration from external data repositories

• Multi-protocol, multi-network interworking

• Signaling orchestration and enhancement

• Centralized hub for agility and service velocity

• Personalized connectivity• IT integration• Monetize investments

• Alternative deployments• Virtualized environments• Decoupled functionality

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
