For the purposes of the present document, the terms and definitions in 3GPP TS 32.101 , 32.102 , 32.600 , 32.741  and the following apply:
Association: in general it is used to model relationships between Managed Objects. Associations can be implemented in several ways, such as:
1. name bindings;
2. reference attributes; and
3. association objects.
This IRP stipulates that containment associations shall be expressed through name bindings, but it does not stipulate the implementation for other types of associations as a general rule. These are specified as separate entities in the object models (UML diagrams).
Managed Element (ME): an instance of the Managed Object Class ManagedElement defined in 3GPP TS 32.622 .
Managed Object (MO): in the context of the present document, a Managed Object (MO) is a software object that encapsulates the manageable characteristics and behaviour of a particular Network Resource. The MO is instance of a MO class defined in a MIM/NRM. This class, called Information Object Class (IOC) has attributes that provide information used to characterize the objects that belong to the class (the term "attribute" is taken from TMN and corresponds to a "property" according to CIM). Furthermore, the IOC can have operations that represent the behaviour relevant for that class (the term "operation" is taken from TMN and corresponds to a "method" according to CIM). The IOC may support the emission of notifications that provide information about an event occurrence within a network resource.
Management Information Model (MIM): also referred to as NRM – see the definition below.
Network Resource Model (NRM): A model representing the actual managed telecommunications network resources that a System is providing through the subject IRP. An NRM identifies and describes the IOCs, their associations, attributes and operations. The NRM is also referred to as "MIM" (see above), which originates from the ITU-T TMN.
