ETSI TR 132 901

ETSI TR 132 901 3GPP TR 22.985 Service requirement for the UDC [5] describes the architecture of the User Data Convergence, aconcept that proposes to move the user data from where it has been distributed and siloed in Network Elements,Applications, and other network resources to a single logical consolidated facility here called User Data Repository(UDR) where it can be accessed, stored and managed in a common way.

The introduction of a User Data Convergence of user data for network services and management applications couldsignificantly enhance the ability of 3GPP based networks to offer complex and combined services. User data can bedecomposed and reformed by a common data model framework (e.g. tree-like data model, rational data model)provided by UDR. In that case, user data categorized by services can be regrouped and identified by user ID, leaving nodata redundancy. Also, convergence in data model will unify the user data access interface and its protocol, which willpromote new service application development. Thereby, the capability of user data convergence can be open to creationof data-less applications.

Methods for data protection against access by unauthorized parties are outside the scope of this document.

3GPP TS 32.181 UDC Framework for Model Handling and Management [3] and 3GPP TS 29.335 UDC; User DataRepository Access Protocol over the Ud interface; Stage 3 [4] provide various types of information and data modelsassociated with the architecture of UDC.These include the Common Baseline Information Model (CBIM) (see 3GPP TS 32.182 [7]), the SpecializedInformation Model (SpIM), Application Information Models (AIMs), Application Data Models (ADMs), and theConsolidated Data Model (CDM) of the User Data Repository (UDR).Figure 1 from 3GPP TS 32.181 UDC Framework for Model Handling and Management [3] shows the operationalenvironment of the UDC.
