Universal Mobile Telecommunications System (UMTS); LTE; Telecommunication management; Fixed Mobile Convergence (FMC) Federated Network Information Model (FNIM) Umbrella Information Model (UIM) (V12.0.0; 3GPP TS 28.620 version 12.0.0 Release 12)
As a result of the analysis of the requirements for the harmonization of the 3GPP and TM Forum Information Models in the context of FMC basic use cases were developed [0]@ [0]. These use cases led to the recognition that it would be necessary to define common model elements applicable for wire-line and wireless networks. This document defines these common model elements. To be noted: - The Umbrella Information Model (UIM) described in this document provides the set of classes etc. that have been agreed for convergence to strengthen consistency of representation in the fixed and mobile environments. For full management of an FNIM solution many other classes will be required in addition to those in the UIM. - The UIM is necessary but not sufficient for implementation. - The UIM cannot be used directly for implementation. Implementation classes must be derived from those in the UIM by Inheritance or some other appropriate mechanism. - Classes derived from those in the UIM (e.g. for the fixed environment) must use different names from those used in the UIM. - Where an implementation class is essentially identical to the abstract class defined in UIM the name of the implementation class should be the same as that of the UIM minus the underscore@ e.g. the UIM class 'Function_' would become 'Function'.
