"The User Data Convergence concept supports a layered architecture, separating the data from the application logic in the 3GPP system, so that user data is stored in a logically unique repository allowing access from core and service layer entities, named application front-ends. Network elements and functionalities should be designed to access profile data remotely and without storing them permanently locally, i.e. the front-ends shall work in a user dataless configuration."

TR 22.985 and TS 22.101 provide the requirements for User data convergence so that user data can be moved from where it originated, to a facility called User Data Repository (UDR) where it can be accessed, stored and managed in a common way.

Convergence of user data unifies the user data access interface and its protocol. In addition, the logical centralization of user data implies the support of user data provisioning, that is, user data manipulation like creation, deletion, reading, modification and other operations.

In order to accommodate multiple applications and services, existing and new ones, a framework for model handling and management of the UDC has been developed including:

– UDC information model infrastructure

– UDC information model handling

– Application management

– Consolidated data model management.
