Nokia announced that Telefonica UK has selected Subscriber Data Management (SDM) software to enhance the security and reliability of the operator’s networks, and to drive 5G services innovation.
Nokia’s SDM, as the heart of Telefonica’s converged mobile core, will oversee functionality for all Telefonica networks and services, including 5G. Nokia’s SDM will be controlling network data in a centralized hub and utilizing containerized micro services to increase both reliability and operational efficiencies.

Nokia’s SDM solution serves approximately 4.8 billion subscribers and devices around the world.

Telefonica’s SDM is delivered using Nokia’s core engineered systems program for fast deployment and rapid upgrades.

The deal is supporting subscriber data management for all Telefonica UK’s 3G, 4G, 5G networks, as well as IP Multimedia Subsystem (IMS), Voice over LTE (VoLTE), Voice over WiFi (VoWiFi) and Voice over 5G (Vo5G) services; along with the operator’s IoT devices and nationwide Smart Metering.

Deployment is expected in the fourth quarter and Nokia will oversee all professional services to complete the migration.

Nokia said it will also deploy Shared Data Layer, a database accessible via industry standard protocols to enable an open ecosystem and the integration of third party applications.

Brendan O’Reilly, CTO of Telefonica UK, said: “Nokia’s Subscriber Data Management software offers secure, robust connectivity capabilities, while simultaneously streamlining our network services. This allows us to better support our growing 5G networks and capture operational efficiency.”
