3.1 Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 [1] 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 [1].

Application Data Model : specific data model used by an application accessing the UDR. It is defined according to the UDC access protocol. It is related to an application information model.

Application Data View: a function of the UDR that enables and limits applications access to data within the UDR.

Application Information Model : specific information model used by an application accessing the UDR. It is defined with the same method as the common baseline information model. It is related to an application data model.

Common Baseline Information Model: basic structure of UDC IOCs, see also definition in 3GPP TS 32.182  [4]

Consolidated Data Model: Data model containing all data of the User Data Repository. It is the result of the implementation of the entire Specialized Information Model in the UDR for all applications.

Information Model: Information Model denotes an abstract, formal representation of entity types, including their properties and relationships, the operations (e.g. read, write…) that can be performed on them, and related rules and constrains. In the information model, entities might have network topology relationship with each other.

Specialized Information Model: Information model containing all information to be stored in the UDR. It is the result of operator specific specialisation of CBIM with addition of imported AIM.
