User Data Repository is one of the key components (functions) of the 5G Core Network and its Service Based Architecture. It’s a converged repository (database) of mobile network subscriber information which is used by other 5G Network Functions to store and retrieve the data, such as subscription data, policy-related data, application data, and subscriber-related data that is permitted to be exposed to 3rd party applications.
User Data Repository implemented as cloud-native function and provides an HTTP2 based RESTful interface for other NFs and provisioning clients to access the data stored.
You will be working as part of the team to develop and enhance the Data Repository function with technologies such as containers (Kubernetes), cloud, multi-clustered systems, microservices, continuous integration, and continuous delivery.
