Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommun
15、ications and Internet converged Services and Protocols for Advanced Networking (TISPAN). The present document is part 1 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: “eX
16、tensible Markup Language (XML) Schema definition“. The NRM (Network Resource Model) is part of the TISPAN Management Information Model (MIM). ETSI ETSI TS 188 005-1 V2.1.1 (2009-02) 5 1 Scope The present document identifies the requirements for the NGN Network Resource Model (NRM). This NRM is an in
17、formation model of the NGN Resources defined in the NGN specified by ETSI TISPAN which captures the management aspects (i.e. the management view of the NGN). Clause 4 of the present document captures the general requirements for the NRM. Clause 5 identifies the NGN subsystems and entities which are
18、modelled in the NGN NRM. Annex A captures agreed Use Cases and annex B is an informative annex capturing proposed Use Cases. This version of the document is based on the TISPAN Release 1 architecture and may be updated to reflect changes in subsequent releases. 2 References References are either spe
19、cific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply.

The present document provides a description of the content and capabilities of NGN Release 1 which need to be supported by the
37、 NRM. NRM related requirements in TS 188 003 1. The present document provides high level requirements for the NRM. The use of the IRP Methodology in TS 132 150 2. The present document provides the documentation structure and concept for the NRM. NGN Overall Functional Architecture ES 282 001 3. The
38、present document identifies the subsystems and functional entities which make up the NGN. 4.1 Reuse of specifications To avoid overlap and duplication, the Network Resource Model should import relevant definitions (e.g. Object classes, attributes, etc.) from the 3GPP, TMF, ITU-T etc. where appropria
39、te. 4.2 Granularity of Managed Objects This clause states requirements on the level of granularity for managed entities. 4.2.1 Motivation, remarks, or examples Based on, (see ES 282 001 3), the TISPAN NGN overall architecture (see figure 2) is the starting point for decomposition of the TISPAN NGN.
40、Entities of this overall architecture are further decomposed recursively. This decomposition is performed in three dimensions: Decomposition into layer entities e.g. Service Layer, Transport Layer (see figure 2), or Transport Control Sublayer (see ES 282 001 3). A layer need not map to a manageable
41、entity. Therefore this kind of decomposition does not motivate a requirement. Decomposition into subsystems e.g. Core IMS, PSTN/ISDN Emulation Subsystem. This kind of decomposition motivates Requirement 1. Decomposition into functional entities e.g. User Profile Service Function, UPSF (see figure 3)
42、, Transfer functions (see figure 2). This kind of decomposition motivates Requirement 2. ETSI ETSI TS 188 005-1 V2.1.1 (2009-02) 8 4.2.2 Requirements Requirement 1: Each subsystem that has manageable aspects which are agreed on the basis of documented technical analysis performed on existing TISPAN
43、specifications or are documented within an agreed Use case for an NGN management interface shall map to one manageable model element of the NGN Network Resource Model. Requirement 2: Each functional entity that has manageable aspects which are agreed on the basis of documented technical analysis per
44、formed on existing TISPAN specifications or are documented within an agreed Use case for an NGN management interface shall map to one manageable model element of the NGN Network Resource Model. 4.3 Inter Domain Management 4.3.1 Motivation, remarks, or examples According to the NGN functional archite
45、cture (see ES 282 001 3), functional entities or subsystems may be distributed over network/service provider domain borders. E.g. a network attachment subsystem, an I-BGF, or a service-layer subsystem that supports nomadism may be distributed between a visited and a home network. Figure 1 is taken f
46、rom ES 282 001 3. It illustrates this multi-domain context.

47、irement 1: The Network Resource Model shall allow management of resources which are shared between administrative domains. 5 NGN Managed Entities ES 282 001 3 describes the overall TISPAN NGN functional architecture, its subsystems and the relationships between them. The present document, together w
48、ith the Functional Architectures of the IMS (see ES 282 007 7), PES (see ES 282 002 4), IMS based PES (see TS 182 012 i.2), NAS (see ES 282 004 5), and RACS (see ES 282 003 6), identifies the entities with the NGN subsystems and the relationships between them. The requirement to manage these entitie
49、s is documented in clause 4.3 (requirements A2 and A8) of TS 188 003 1.
