For the purposes of the present document, the following terms and definitions apply.
is any information or set of information required to give software or equipment or combinations thereof a specific state of functionality.
Element Manager (EM):
Information Object Class (IOC):
Integration Reference Point (IRP):
Information Service (IS):
Solution Set (SS):
IRP Solution Set:
Managed Object (MO):
provides a package of end-user functions for management of a set of closely related types of Network Elements (NEs). These functions can be divided into two main categories:
Element Management Functions for management of NEs on an individual basis. These are basically the same functions as supported by the corresponding local terminals.
Sub-Network Management Functions that are related to a network model for a set of NEs constituting a clearly defined sub-network, which may include relations between the NEs. This model enables additional functions on the sub-network level (typically in the areas of network topology presentation, alarm correlation, service impact analysis and circuit provisioning).
an abstract entity, which may be accessed through an open interface between two or more systems, and representing a Network Resource (NR) for the purpose of management. The Managed Object (MO) is an instance of a Managed Object Class (MOC) as defined in a Management Information Model (MIM). The MIM does not define how the MO or NR is implemented; only what can be seen in the interface.
Managed Object Class (MOC):
a description of all the common characteristics for a number of MOs, such as their attributes, operations, notifications and behaviour.
Management Information Model (MIM):
also referred to as NRM - see the definition below. There is a slight difference between the meaning of MIM and NRM - the term MIM is generic and can be used to denote any type of management model, while NRM denotes the model of the actual managed telecommunications Network Resources (NRs).
Network Element (NE):
is a discrete telecommunications entity, which can be, managed over a specific interface e.g. the RNC.
Network Manager (NM):
provides a package of end-user functions with the responsibility for the management of a network, mainly as supported by the EM(s) but it may also involve direct access to the NEs. All communication with the network is based on open and well-standardised interfaces supporting management of multi-vendor and multi-technology NEs.
Network Resource (NR):
is a component of a NE, which can be identified as a discrete separate entity and is in an object oriented environment for the purpose of management represented by an abstract entity called Managed Object (MO).
Network Resource Model (NRM):
Object Management Group (OMG):
Operations System (OS):
indicates a generic management system, independent of its location level within the management hierarchy.
