Scope

The present document specifies the Transport Network (TN) interface Network Resource Model (NRM) that can be
communicated between an IRPAgent and an IRPManager for telecommunication network management purposes,
including management of converged networks.
This document specifies the semantics and behaviour of information object class attributes and relations visible across
the reference point in a protocol and technology neutral way. It does not define their syntax and encoding.
The "Transport Network (TN) Interface Network Resource Model (NRM) IRP" comprises a set of specifications
defining Requirements, a protocol neutral Network Resource Model (NRM) and corresponding Solution Set(s).
The present document:
- Specifies the protocol neutral Transport Network (TN) interface Network Resource Model (NRM) Integration
Reference Point (IRP); Information Service (IS). It reuses relevant parts of the generic NRM in TS 28.622 [6],
either by direct reuse or sub-classing, and in addition to that defines Transport specific Managed Object Classes.
The Configuration Management (CM) area is very large. The intention is to split the specification of the related
interfaces in several IRPs - as described in the Introduction clause above. An important aspect of such a split is that the
Network Resource Models (NRMs) defined in different IRPs containing NRMs are consistent, and that NRMs
supported by an IRPAgent implementation can be accessed as one coherent model through one IRP Information
Service.
In order to access the information defined by this NRM, an IRP Information Service (IS) is needed, such as the Basic
CM IRP: IS (TS 32.602 [7]) or the Bulk CM IRP: IS (TS 32.612 [8]). However, which Information Service that is
applicable is outside the scope of this document.
Finally, regarding the support of the State Management IRP: IS (TS 28.625 [16]), all NRMs of one release shall support
the same State Management IRP version.
This specification is related to 3GPP TS 28.625 [16].
