3GPP TS 28.662 version 15.3.0 Release 15 6 ETSI TS 128 662 V15.3.0 (2020-01)
1 Scope
The present document specifies the Generic Radio Access Network (RAN) 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.
In order to access the information defined by this NRM, an Interface IRP such as the "Basic CM IRP" is needed (3GPP
TS 32.602 [5]). However, which Interface IRP is applicable is outside the scope of the present document.
2 References
The following documents contain provisions which, through reference in this text, constitute provisions of the present
document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or
non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including
a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same
Release as the present document.
