0  IntroductionWord‑p. 5
User Data Convergence (UDC) presents a layered architecture where user data is accessible at a logically unique repository called User Data Repository (UDR). One or more dataless applications access the user data that is stored in the UDR. In this context, applications can be front ends, for example an HSS-FE or an HLR-FE, or application servers. In order to support UDC, a Common Baseline Information Model is defined in this specification.

1  ScopeWord‑p. 6
The present document specifies a Common Baseline Information Model for UDC [2]. This information model denotes an abstract, formal representation of entity types that are common to many applications using the UDR. CBIM describes the basic IOCs of UDC, their properties and their relationships. Detailed requirements for the specification of this Common Baseline Information Model are given in TR 22.985 and TS 22.101.
From the Common Baseline Information Model specialized information models and data models can be derived. All these derived models are out of the scope of this specification.

  • References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
  • For a specific reference, subsequent revisions do not apply.

3  Definitions and abbreviations

3.1  Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Common Baseline Information Model:
an abstract, formal representation of entity types common to many applications using the UDR. CBIM describes the basic IOCs of UDC, their properties and their relationships, so that these IOCs constitute the baseline for any given application. Therefore, CBIM provides flexibility (in its data structure and content), extensibility and multi-application approach. In particular, CBIM provides support for the concepts of Subscription, Service Profile, End User, Identifiers, End User Group, and End Device, among others. CBIM does not define the models that are associated with each application and that are under their responsibility.
