Cloud signaling director
Simplify, scale and secure your 4G signaling and prepare for 5G
Nokia Cloud Signaling Director (CSD) addresses the challenges of 4G traffic growth while setting the stage for 5G by simplifying interoperability, enabling massive scalability, and securing signaling. The CSD is Nokia's cloud-native software for 4G’s Diameter Signaling Controller (DSC), and as a new function it provides control for the 5G’s HTTP/2 signaling, both within the 5G core and between the 5G core and untrusted peer networks & untrusted slices (e.g., enterprise, IoT).
Popular LTE services are driving rapid growth of Diameter traffic
Diameter-based control plane traffic is escalating as consumers embrace advanced mobile broadband services. This growth results in an increasingly complex control topology and creates inefficiency and unpredictability.
To deliver the rich, secure experiences your customers want, you need an intelligent product that brings greater flexibility to the signaling control plane.
Performance, automation and new business drive 5G
Signaling changes from 4G’s Diameter to 5G’s HTTP/2 and JSON. Challenges in deploying your 5G core include:
- Fully utilizing the 5G core’s Service Based Architecture (SBA), including dynamic configurations, massive scaling, and resilience.
- Ensuring interoperability across the 5G core, both within and between networks.
- Building in security from the start for internal and external threats.
