32.106-53GPPConfiguration Management (CM)Part 5: Basic CM Integration Reference Point (IRP): Information model (including Network Resource Model (NRM)Telecommunication managementTS
For the purposes of the present document, the following terms and definitions apply. For terms and definitions not found here, please refer to 3GPP TS 32.101 , 3GPP TS 32.102  and 3GPP TS 32.106-1 .
Association: In general it is used to model relationships between Managed Objects. Associations can be implemented in several ways, such as:
- name bindings,
- reference attributes, and
- 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). Currently (in Release 99) however, all (non-containment) associations are modelled by means of reference attributes of the participating MOs.
Managed Element (ME): An instance of the Managed Object Class G3ManagedElement.
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. An MO class 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, an MO class 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). An MO class may support notifications that provide information about an event occurrence within a network resource.
Management Information Base (MIB): A MIB is an instance of an NRM and has some values on the defined attributes and associations specific for that instance. In the context of the present document, an MIB consists of:
- a Name space (describing the MO containment hierarchy in the MIB through Distinguished Names),
- a number of Managed Objects with their attributes and
- a number of Associations between these MOs. Also note that TMN (ITU-T Recommendation X.710 ) defines a concept of a Management Information Tree (also known as a Naming Tree) that corresponds to the name space (containment hierarchy) portion of this MIB definition. Figure 1 depicts the relationships between a Name space and a number of participating MOs (the shown association is of a non-containment type)

Management Information Model (MIM): Also referred to as NRM – see the definition below.
Name space: A name space is a collection of names. The IRP name convention (see 3GPP TS 32.106-8 ) restricts the name space to a hierarchical containment structure, including its simplest form – the one-level, flat name space.
All Managed Objects in a MIB shall be included in the corresponding name space and the MIB/name space shall only support a strict hierarchical containment structure (with one root object). A Managed Object that contains another is said to be the superior (parent); the contained Managed Object is referred to as the subordinate (child). The parent of all MOs in a single name space is called a Local Root. The ultimate parent of all MOs of all managed systems is called the Global Root.
Network Resource Model (NRM): A model representing the actual managed telecommunications network resources that a System is providing through the subject IRP. An NRM describes Managed Object Classes, their associations, attributes and operations. The NRM is also referred to as “MIM” (see above), which originates from the ITU-T TMN.
Node B: A logical node responsible for radio transmission/reception in one or more cells to/from the User Equipment.
It terminates the Iub interface towards the RNC.
