1 Scope
UML provides a rich set of concepts, notations and model elements to model distributive systems. This paper
documents the necessary and sufficient set of UML notations and model elements, including the ones built by the UML
extension mechanism <> to model network management systems and their managed nodes.This set of
notations and model elements is called the FMC Model Repertoire; see also 3GPP TS 32.107 [5] and 3GPP TS 28.620
[6].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [X] and the following
apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP
TR 21.905 [9].Naming attribute: It is a class attribute that holds the class instance identifier. See attribute id of Top_
[6]. See examples of naming attribute in 3GPP TS 32.300 [3].
Lower Camel Case: It is the practice of writing compound words in which the words are joined without spaces. Initial
letter of all except the first word shall be capitalized. Examples: ‘managedNodeIdentity’ and ‘minorDetails’ are the
LCC for “managed node identity” and “minor details” respectively.
Upper Camel Case: It is the Lower Camel Case except that the first letter is capitalised. Examples:
‘ManagedNodeIdentity’ and ‘MinorDetails’ are the UCC for “managed node identity” and “minor details” respectively.
Well Known Abbreviation: An abbreviation can be used as the modelled element name or as a component of a
modelled element name. The abbreviation, when used in such manner, must be documented in the same document
where the modelled element is defined.

3.2 Abbreviations
For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 [9], 3GPP TS 28.620 [6] and the
following apply. An abbreviation defined in the present document takes precedence over the definition of the same
abbreviation, if any, in 3GPP TR 21.905 [X], and 3GPP TS 28.620 [6].

4 Requirements
The UML notations and model elements captured in this repertoire shall be used to model behaviours of the
systems/entities such as the Umbrella Information Model (UIM) of the FNIM in 3GPP TS 28.620 [6].
5 Model elements and notations
5.1 General
Note that the graphical notation in this document is only used to represent particular model elements. Although the
graphical notation is a correct representation of the model element, it may not be a valid representation of a UML class
diagram.
The examples used in this document are for illustration purposes only and may or may not exist in specifications.
UML properties not described in this document shall not be used in specifications based on this repertoire.
5.2 Basic model elements
UML has defined a number of basic model elements. This subclause lists the subset selected for use in specifications
based on this repertoire. The semantics of these selected basic model elements are defined in [1].
For each basic model element listed, there are three parts. The first part contains its description. The second part
contains its graphical notation examples and the third part contains the rule, if any, recommended for labelling or
naming it.
The graphical notation has the following characteristics:
→ Subclause 7.2.7 of [2] specifies "A class is often shown with three compartments. The middle compartment
holds a list of attributes while the bottom compartment holds a list of operations" and "Additional
compartments may be supplied to show other details". This repertoire only allows the use of the name (top)
compartment and attribute (middle) compartment. The operation (bottom) compartment may be present but is
always empty, as shown in the figure below.
→ Classes may or may not have attributes. The graphical notation of a class may show an empty attribute (middle)
compartment even if the class has attributes, as shown in figure below.
→ The visibility symbol shall not appear along with the class attribute, as shown below.
→ The use of the decoration, i.e. the symbol in the name (top) compartment, is optional.

5.2.1 Attribute
5.2.1.1 Description
It is a typed element representing a property of a class. See 10.2.5 Property of [1].
An element that is typed implies that the element can only refer to a constrained set of values.
See 10.1.4 Type of [1] for more information on type.
See 5.3.4 and 5.4.3 for predefined data types and user-defined data types that can apply type information to an element.
The following table captures the properties of this modelled element.
