4.2.1 Attributes and relationships

This sub clause depicts the set of IOCs that encapsulate information relevant for this service. This sub clause provides the overview of all information object classes in UML. Subsequent subclasses provide more detailed specification of various aspects of these information object classes.

Figure 4.2.1.1 shows the name-containment relation and other types of relations of the Transport Network NRM.

Figure 4.2.1.1: Transport Network NRM Containment/Naming and Association diagram

Each IOC is identified with a Distinguished Name (DN) according to 3GPP TS 32.300 [4] that expresses its containment hierarchy. As an example, the DN of a IOC representing a ATMPathTerminationPoint could have a format like:

SubNetwork=Sweden,meContext=MEC-Gbg-1,ManagedElement=RNC-Gbg-1, TransportNetworkInterface=ATM-1, ATMPathTerminationPoint=Gbg-1.

NOTE 1: The listed cardinality numbers represent transient as well as steady-state numbers, and reflect all managed object creation and deletion scenarios.

4.2.2 Inheritance

This sub-clause depicts the inheritance relationships that exist between IOCs.

Figure 4.2.2.1 shows the inheritance hierarchy for the Transport Network NRM.
