Subscriber Data Management (SDM)
Ready for 5G, cloud and future networks
The roll out of 5G and cloud technologies places new demands on Subscriber Data Management (SDM). As well as supporting the operational needs of legacy networks, SDM must also fulfill new 3GPP-defined requirements.
SDM sits at the heart of the core network, storing valuable data used by diverse telecoms services. To make the most of 5G, transform your SDM into open, extensible cloud-native software applications that provide standards-based functions and enable rapid innovation.
What is Subscriber Data Management (SDM)?
Complying with 3GPP User Data Convergence and 5G standards, Nokia SDM centralizes user data into a single, robust Unified Data Repository (UDR) that hosts applications and ensures SDM security. The Unstructured Data Storage Function (UDSF) enables control applications to store their session data and become session stateless.
Support unified subscriber access management with Nokia Registers:
- 5G subscriber authorization, registration and mobility management are supported by the Unified Data Management (UDM) and Authentication Server Function (AUSF)
- 2G/3G/4G are supported by Home Subscriber Server (HSS) and Home Location Register (HLR) interworking with 5G UDM for domain spanning use cases.
Simplify subscriber and services management:
- Securely identify terminals accessing the network the key solution is Equipment Identity Register (EIR)

Ready your access network to handle more users, different devices and run new services
- Combine 3G/4G policy flow rules and the 5G Policy Control Function (PCF) to generate revenue from new use cases
Use stateless network functions for the highest performance
- The UDSF supports 5G network functions in a stateless architecture for a highly reliable core network.
Innovate rapidly with open programmability capabilities
- Create new use cases with the Network Exposure Function (NEF) that allows authorized applications to securely access subscriber data in the 5G network.
With Nokia SDM, user data is centralized in a secure, highly scalable repository. As a single point of provisioning, this saves costs and substantially shortens the time taken to launch new technologies and services or to activate new customers.

Boost revenues with new market opportunities
Nokia SDM is open and flexible to easily integrate third-party applications that meet new customer demands. Operators gain the reliability, scalability and flexibility they need to address a wide range of requirements when deploying IoT or new services for vertical markets.
How to move SDM to 5G
Nokia SDM paves the way for networks to evolve to the telco cloud and 5G. Virtualized front-end applications are already available for the smooth progression to Nokia Shared Data Layer (SDL), bringing the benefits of the cloud. Your investment is protected and you can upgrade your network at a pace matched to your needs.
