1 Scope
The TS 28.62x-series (Generic Network Resources IRP) define an Integration Reference Point (IRP) through which an
"IRPAgent" (typically an Element Manager or Network Element) can communicate Network Management related
information to one or several "IRPManagers" (typically Network Managers).
This TS-family specifies a generic Network Resource Model, NRM (also referred to as a Management Information
Model - MIM) with definitions of Information Object Classes (IOCs) and Managed Object Classes (MOCs).
The present document specifies the Solution Set definition for the Generic NRM IRP.
The Solution Set definition is related to 3GPP TS 28.622 V15.2.X [4].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [15], 3GPP TS 32.101
[1], 3GPP TS 32.102 [2], 3GPP TS 32.600 [3], 3GPP TS 28.622 [4] 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 [15] and 3GPP TS
32.101 [1], 3GPP TS 32.102 [2] and 3GPP TS 32.600 [3] and 3GPP TS 28.622 [4].
XML file: file containing an XML document
XML document: composed of the succession of an optional XML declaration followed by a root XML element
NOTE: See [8]; in the scope of the present document.
XML declaration: it specifies the version of XML being used
NOTE: See [8].
XML element: has a type, is identified by a name, may have a set of XML attribute specifications and is either
composed of the succession of an XML start-tag followed by the XML content of the XML element followed by an
XML end-tag, or composed simply of an XML empty-element tag; each XML element may contain other XML
elements
NOTE: See [8].
empty XML element: having an empty XML content; an empty XML element still possibly has a set of XML attribute
specifications; an empty XML element is either composed of the succession of an XML start-tag directly followed by
an XML end-tag, or composed simply of an XML empty-element tag
NOTE: See [8].
XML content (of an XML element): empty if the XML element is simply composed of an XML empty-element tag;
otherwise the part, possibly empty, of the XML element between its XML start-tag and its XML end-tag
XML start-tag: the beginning of a non-empty XML element is marked by an XML start-tag containing the name and
the set of XML attribute specifications of the XML element
NOTE: See [8].
XML end-tag: the end of a non-empty XML element is marked by an XML end-tag containing the name of the XML
element
NOTE: See [8].
XML empty-element tag: composed simply of an empty-element tag containing the name and the set of XML attribute
specifications of the XML element.
NOTE: See [8].
XML attribute specification: has a name and a value
NOTE: See [8].
DTD: defines structure and content constraints to be respected by an XML document to be valid with regard to this
DTD
NOTE: See [8].
XML schema: more powerful than a DTD, an XML schema defines structure and content constraints to be respected
by an XML document to conform with this XML schema; through the use of XML namespaces several XML schemas
can be used together by a single XML document; an XML schema is itself also an XML document that shall conform
with the XML schema for XML schemas

NOTE: See [10] and [11].
XML namespace: enables qualifying element and attribute names used in XML documents by associating them with
namespaces identified by different XML schemas
NOTE: See [12], in the scope of the present document.
XML complex type: defined in an XML schema; cannot be directly used in an XML document; can be the concrete
type or the derivation base type for an XML element type or for another XML complex type; ultimately defines
constraints for an XML element on its XML attribute specifications and/or its XML content
NOTE: See [10] and [11].
XML element type: declared by an XML schema; can be directly used in an XML document; as the concrete type of
an XML element, directly or indirectly defines constraints on its XML attribute specifications and/or its XML content;
can also be the concrete type or the derivation base type for another XML element type
NOTE: See [10] and [11].

- 3GPP Generic NRM IRP JSON Definitions (Annex C).

3GPP TS 28.623 version 15.4.0 Release 15 9 ETSI TS 128 623 V15.4.0 (2020-01)
Annex A (normative):
CORBA Solution Set
A.0 General
This annex contains the CORBA Solution Set for the IRP whose semantics is specified in Generic NRM IRP:
Information Service (3GPP TS 28.622 [4]).
A.1 Architectural features
The overall architectural feature of Generic Network Resources IRP is specified in 3GPP TS 28.622 [4].
This clause specifies features that are specific to the CORBA SS.
A.1.1 Syntax for Distinguished Names
The syntax of a Distinguished Name is defined in 3GPP TS 32.300 [5].
A.1.2 Rules for NRM extensions
A.1.2.0 Introduction
This clause discusses how the models and IDL definitions provided in the present document can be extended for a
particular implementation and still remain compliant with 3GPP SA5's specifications.
A.1.2.1 Allowed extensions
Vendor-specific MOCs may be supported. The vendor-specific MOCs may support new types of attributes.
The 3GPP SA5-specified notifications may be issued referring to the vendor-specific MOCs and vendor-specific
attributes. New MOCs shall be distinguishable from 3GPP SA5 MOCs by name. 3GPP SA5-specified and vendor-
specific attributes may be used in vendor-specific MOCs. Vendor-specific attribute names shall be distinguishable from
existing attribute names.
NRM MOCs may be subclassed. Subclassed MOCs shall maintain the specified behaviour of the 3GPP SA5's superior
classes. They may add vendor-specific behaviour with vendor-specific attributes. When subclassing, naming attributes
cannot be changed. The subclassed MOC shall support all attributes of its superior class. Vendor-specific attributes
cannot be added to 3GPP SA5 NRM MOCs without subclassing.
When subclassing, the 3GPP SA5-specified containment rules and their specified cardinality shall still be followed.
As an example, ManagementNode (or its subclasses) shall be contained under SubNetwork (or its subclasses).
Managed Object Instances may be instantiated as CORBA objects. This requires that the MOCs be represented in IDL.
3GPP SA5's NRM MOCs are not currently specified in IDL, but may be specified in IDL for instantiation or
subclassing purposes. However, management information models should not require that IRPManagers access the
instantiated managed objects other than through supported methods in the present document.
Extension rules related to notifications (Notification categories, Event Types, Extended Event Types etc.) are for further
study.
A.1.2.2 Extensions not allowed
The IDL specifications in the present document cannot be edited or altered. Any additional IDL specifications shall be
specified in separate IDL files.

3GPP TS 28.623 version 15.4.0 Release 15 10 ETSI TS 128 623 V15.4.0 (2020-01)
IDL interfaces (note: not MOCs) specified in the present document may not be subclassed or extended. New interfaces
may be defined with vendor-specific methods.

A.2 Mapping
A.2.1 General mapping
Attributes modelling associations as defined in the NRM (here also called "reference attributes") are in this SS mapped
to attributes. The names of the reference attributes in the NRM are mapped to the corresponding attribute names in the
MOC. When the cardinality for an association is 0.1 or 1.1 the datatype for the reference attribute is defined as an
MOReference. The value of an MO reference contains the distinguished name of the associated MO. When the
cardinality for an association allows more than one referred MO, the reference attribute will be of type
MOReferenceSet, which contains a sequence of MO references.
A.2.2 Information Object Class (IOC) mapping
This Solution Set supports reference attributes for relations other than containment relations between objects. Reference
attributes are therefore introduced in each MOC where needed.
