It is featured as sending management command to network element management unit and receiving management information by operation support unit, operating network device according by network element management unit, setting interface between operation support unit and network element management unit to be north-direction interface and setting a unified interface between operation support unit and network element management unit.
Description
Technical field
The present invention relates to a kind of network management system, the network management system in especially a kind of mobile communications network.
Background technology
At present, along with 3G (Third Generation) Moblie (The Third Generation Mobile Communication; Development 3G) has proposed new demand to the network management system of mobile communication.In the 3G (Third Generation) Moblie network management system, two mutual entities have been born two roles respectively mutually: manager (Manager) and succedaneum (Agent).Gerentocratic task is to send administration order and receive the notice that the succedaneum sends; Succedaneum's task is the direct relevant management object of management, and the administration order that the receiving management person sends and to the response of manager's return (during the operation of affirmation type) also can initiatively be given notice to the manager when needed.
In the network management of 3G (Third Generation) Moblie net, the operation support system of operator (Operations support System; OSS) born the effect of Manager, OSS can manage network element device (the Network Element of distinct device manufacturer; NE); The Element management system of NE (Element Management System; EMS), perhaps be called (the Operationand Maintenance Center of operation maintenance center; OMC) born the effect of Agent.3G (Third Generation) Moblie standard collaboration items tissue (3rdGeneration Partnership Project; 3GPP) introduce the definition of northbound interface (Itf-N), be used to describe the network management interface between above-mentioned OSS and the EMS.Northbound interface is as shown in Figure 1:
Among Fig. 1, northbound interface Itf-N provides northbound interface by OMC to OSS between OSS and OMC, and the interface between OMC and the NE is the device interior interface at this moment, and equipment manufacturers can define voluntarily to this internal interface.
As a rule, different OMC that equipment manufacturers produced or NE have nothing in common with each other, in order to realize that 3G (Third Generation) Moblie standard collaboration items tissue proposes above-mentioned standardized northbound interface, different equipment vendors need all will realize a normalized northbound interface in each OMC system, it between the OMC of manufacturer of above-mentioned standardized northbound interface and current version coupled relation closely, this just means, when the OMC system upgrade, northbound interface itself also needs to upgrade thereupon, close-coupled between this northbound interface and the OMC does not meet the development trend that coupling weakens between the mixed-media network modules mixed-media.And, when certain OSS of operator upgrades, northbound interface correspondingly also will upgrade thereupon, otherwise uses the OSS version of new information model can't manage old OMC version, and this coupling has influence on the flexibility and the extensibility of northbound interface to a great extent.
Summary of the invention
Therefore, main purpose of the present invention is to provide the network management system in a kind of mobile communications network, this system can provide a kind of in operator operation support system and the general northbound interface between the operation maintenance center of network element device, this general-purpose interface can reduce the coupling between the mixed-media network modules mixed-media, makes different Element management systems to be integrated into by the mode of plug and play in the above-mentioned general northbound interface.
