Into ITU (InternationalTelecommunicatiohs Union, International Telecommunication Union) TMN
NE management layer in (TelecommunicatiohsManagement Network Model, telecommunication management network)
(ElememManagement Layer, referred to as EML) function, that is, complete the pipe of one or more mobile communication equipments (network element)
Function is managed, the network element managed is typically from same equipment supplier.NMS mainly completes the network management in ITU TMN
Layer (Network Management Layer, referred to as NML) function, is responsible for the management of all network elements in a managed network.
Interface between NMS and EMS is referred to as northbound interface (Itf-N), and operator is usually to be led in NMS by northbound interface and EMS
News manage the equipment of different vendor and the purpose of correlation function to reach.
From 3GPP (The 3rd Generation Partnership Project, third generation partner program) specification
From the perspective of, it is referred to as IRPManager (integrated reference point manager) positioned at the northbound interface processing function of NMS layers, is located at
The northbound interface processing function of EMS layers is referred to as IRPAgent (integrated reference point agency).Specific IRPManager's and IRPAgem
Definition refers to 3GPP specifications " TS32.150 3rd Generation Partnership Project；Technical
Specification GroupServices and System Aspects；Telecommunication management；
IntegrationReference Point(IRP)Concept and definitions”.So when NMS is connect by north orientation
When mouth interacts with EMS, really NMS first passes through IRPManager, is entered by IRPManager by northbound interface and IRPAgent
Row interaction, IRPAgent pass to EMS again, and vice versa.

Operated for self-organizing operation or SON.One can be run into when there are multiple SON functions to need and carry out self-organizing operation to same network element
A little problems, mainly collision problem.For example, working as has multiple SON functions to need to change the same parameter of same network element, without
Which when the new parameter value of same SON functions preparation modification is again different, can not determine to need actually with the modification of SON functions
Value is defined.If uncoordinated between each other, each SON functions are modified by the demand of oneself, then may cause each SON work(
After being changed finding oneself amended parameter value by other SON functions, again attempt to what is modified by the needs of oneself
Situation, so as to cause ping-pong.
