IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN).
The present document is part 2 of a multi-part deliverable covering Network and Service Management; Network
Resource Model, as identified below:
Part 1: "Requirements";
Part 2: "Information Service";
Part 3: "eXtensible Markup Language (XML) Schema definition".

1 Scope
The present document identifies the Information Service for the manageable resources present in the NGN Transport
and Service Layers.
The present document specifies the protocol neutral NGN Network Resource Model Information Service (IS). It reuses
relevant parts of the IMS NRM IRP: IS in TS 132 732 [1] and the Generic NRM IRP: IS in TS 132 622 [2], either by
direct reuse or sub-classing, and in addition to that defines NRM specific Information Object Classes.
This is the first version of the NGN Network Resource Model. The current version does not:
• capture all the attributes of the Network Resources. These will be addressed in future revisions of the present
document;
• address the non-IMS based PSTN ISDN Emulation Subsystem, IPTV Subsystems and the additional Network
Resources required supporting Emergency Calls. These will be added in future revisions of the present
document;
• provide guidance on the permitted value ranges of Attributes.
This version of the NRM is linked to 3GPP NRM using naming and inheritance, however a need to link the NRM to the
TeleManagement Forum's Shared Information Data Model (SID) has been identified and will be addressed in future
revisions of the present document. A comparison of 3GPP and SID inheritance is contained in annex A.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.

4 High Level Model
In this clause, a high level context for the TISPAN Network Resource Model is given. The section is organized with an
initial textual description, followed by a general diagram which aims to depict a high level model of the Transport and
Service layers of the NGN.
The goal of the NRM within the current TISPAN release is to model the manageable network resources within the NGN
Service and Transport Layers.
The high level decomposition of the NGN Service and Transport Layer entities, as identified in the TISPAN
Architecture documents, is illustrated in figure 4.1. The Network Resource Model provides a model of the manageable
aspects of these entities.

5 Information Object Classes
5.1 Imported information entities and local labels
This clause identifies a list of information entities (e.g. information object class, information relationship, information
attribute) that have been defined in other specifications and that are imported in the present document. This includes
information entities from other specifications imported for inheritance purpose. Each element of this list is a pair (label
reference, local label). The label reference contains the name of the specification where it is defined, the type of the
information entity and its name. The local label of imported information entities can then be used throughout the
specification instead of the label reference.
This information is provided in table 5.1.1.

NOTE 1: It should be noted that the definition of Link Information Object Class imported from TS 132 622 [2] will
need to be clarified as follows:
- In TS 132 622 [2] it states that the Link IOC "represents a communication link or reference point
between two network entities. The Link IOC does not indicate whether the represented
communication link or reference point is a physical or logical entity".
- In the context of the NGN, the Link represents the relationship between two "NGN Functional
Entities".
NOTE 2: AsFunction IOC: In the TISPAN NRM, this IOC represents ASF Type 2 Application Servers
(see ES 282 001 [3]) in the cases specified in the IOC definition of TS 132 732 [1]. Furthermore, the
IOC is used for subclassing of TISPAN specific IOCs.
NOTE 3: CamelImSsfAsFunction IOC: In the TISPAN NRM, this IOC represents ASF Type 2
(see ES 282 001 [3]) of type IM-SSF Application Server using CAMEL (see ES 282 007 [7]).
NOTE 4: OsaScsAsFunction IOC: In the TISPAN NRM, this IOC represents ASF Type 2 (see ES 282 001 [3])
of type OSA SCS Application Server (see ES 282 007 [7]).
NOTE 5: SipAsFunction IOC: In the TISPAN NRM, this IOC represents ASF Type 2 (see ES 282 001 [3]) of
type SIP Application Server (see ES 282 007 [7]).
NOTE 6: Link_As_Cscf IOC: In the TISPAN NRM, this IOC represents the ISC reference point between
S-CSCF and ASF Type 2 (see ES 282 001 [3] and ES 282 007 [7]). TS 132 732 [1] positions this IOC
between the AsFunction IOC and the CscfFunction IOC in the case of non-role based modelling
of CSCF (see definition of the CscfFunction IOC of TS 132 732 [1]).
NOTE 7: Link_As_Icscf IOC: In the TISPAN NRM, this IOC represents the Ma reference point between
I-CSCF and ASF Type 2 (see ES 282 001 [3] and ES 282 007 [7]).
ETSI
12 ETSI TS 188 005-2 V2.1.1 (2009-02)
NOTE 8: Link_As_Scscf IOC: In the TISPAN NRM, this IOC represents the ISC reference point between
S-CSCF and ASF Type 2 (see ES 282 001 [3] and ES 282 007 [7]).
NOTE 9: Link_As_Slf IOC: In the TISPAN NRM, this IOC models the Dh reference point between SLF and ASF
Type 2 (see ES 282 001 [3] and ES 282 007 [7]).
NOTE 10: In the TISPAN NRM, this IOC represents the manageable aspects of the NGN Functional Entity
(see ES 282 001 [3] and ES 282 007 [7]) with same name as the functionality the IOC is defined to
represent in TS 132 732 [1].
NOTE 11: In the TISPAN NRM, this link IOC represents the NGN reference point (see ES 282 001 [3] and
ES 282 007 [7]) with same name as the reference point the IOC is defined to represent in
TS 132 732 [1] and is to be used between the two IOCs specified by the IOC name (see definition of
Link in TS 132 622 [2]).
5.2 Class diagram
5.2.1 Attributes and relationships
This clause depicts the set of IOCs that encapsulate information relevant for modelling the NGN Transport and Service
Layer. 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 information object classes
defined in the present document.
NOTE: In this release of the NRM, IOCs representing NRM Functions are contained by the ManagedElement
IOC. This usage of the ManagedElement IOC presents issues in the context of the TISPAN NRM, related
to the fact that this entity has in the definition the following text: "This IOC represents a
telecommunication equipment or TMN entities within the telecommunications network that performs
Managed Element (ME) functions, i.e. provides support and/or service to the subscriber"
(see TS 132 622 [2]). This may not be appropriate for some NGN Functions (e.g. Application Servers
realized on a distributed systems). The question is if ManagedElement has a too strong correspondence
with traditional Network Equipment and its management by Network or Element Management systems to
be used for the TISPAN NRM.
