The Shared Data Layer is the cornerstone to consolidate subscriber and session data within a highly reliable and scalable repository. Separating data from processing boosts business agility, making it easier to explore new services and revenue opportunities, many based on third-party cloud applications. Subscriber Data Management (SDM) sits at the heart of the core network, storing valuable data used by diverse telecoms services. With the arrival of 5G and the evolution to cloud architectures, SDM must fulfil new 3GPP- defined requirementsas well as the operational needs of legacy network elements. SDM has been deployed for 4G used by billions of subscribers globally in some of the world’s largest networks, but now faces new challenges raised by 5G. The Nokia cloud native Shared Data Layer (SDL) offers unparalleled network scalability and reliability to help manage telco Network Functions (NFs) and is now a contribution to standardization
