6.2.1 Attributes and relationships

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

The figures below show the containment/naming hierarchy and the associations of the GERAN NRM.

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

NOTE 2: Void.

NOTE 3: The ExternalBssFunction is used in the Core Network NRM.

Figure 6.1: GERAN NRM Containment/Naming and Association diagram

Each Managed Object is identified with a Distinguished Name (DN) according to 3GPP TS 32.300 [13] that expresses its containment hierarchy. As an example, the DN of an IOC representing a cell could have a format like:

SubNetwork =Sweden,MeContext =MEC-Gbg-1, ManagedElement =RNC-Gbg-1, BssFunction=BSS1.

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

NOTE 2: Each instance of the VsDataContainer shall only be contained under one IOC. The VsDataContainer can be contained under IOCs defined in other NRMs.

Figure 6.2: GERAN NRM Containment/Naming and Association diagram

The VsDataContainer is only used for the Bulk CM IRP.

6.2.2 Inheritance

This clause depicts the inheritance relationships that exist between IOCs.

Figure 6.3 shows the inheritance hierarchy for the GERAN NRM.

6.3.4 GsmRelation

6.3.4.1 Definition

This IOC contains a Neighbour cell Relation (NR) from a source cell to a target cell, where the target cell is a GsmCell or ExternalGsmCell instance.

NOTE: In handover relation terms, the cell containing the GsmRelation object is the source cell for the handover. The cell referred to in the GsmRelation object is the target cell for the handover. This defines a one-way handover relation where the direction is from source cell to target cell.

The source cell can be a GsmCell instance. This is the case for an Intra-GERAN NR.

The source cell can be an UtranGenericCell instance. This is the case for Inter-RAT NR from UTRAN to GERAN. See 3GPP TS 32.642 [19].

The source cell can be an EUtranGenericCell instance. This is the case for Inter-RAT NR from E-UTRAN to GERAN. See 3GPP TS 32.762 [22].
