Embodiment
The northbound interface of the present invention between EMS and NMS uses the part hang-up method of interface, only needs carried out the object execution hang-up of interim Operation and Maintenance, do not influence the operation of other objects.
See also Fig. 4, be the building-block of logic of northbound interface inside IRP.Northbound interface between EMS and the NMS is the passage that implementation and operation is safeguarded, on logic function, this interface can be decomposed into each IRP, and each IRP, such as IRP, performance management IRP and the configuration management IRP of general utility functions, its behavior all comprises some operation and notices based on object and attribute thereof.NMS comprises general utility functions IRP Manager, performance management IRP Manager and configuration management IRPManager, and EMS comprises general utility functions IRP Agent, performance management IRP Agent and configuration management IRP Agent.
The present invention defines the operation that a part is hung up northbound interface (patiallySuspendItfN) earlier on the general utility functions IRP of northbound interface, this operation need be carried four class input parameters, be that the manager quotes (managerReference), basic management object instance (baseMOInstance), object range (MoScope) and communication link supervision permission flag (CSNoteAllowed), wherein the manager quotes expression by the part pending operation of which IRP Manager initiation to current I RP Agent; The basic management object instance represents IRP Manager need to which object instance operating part pending operation of current I RP Agent; Object range represents then whether this part pending operation is applied to the subobject of specified hang-up object instance; Communication link monitors that permission flag represents the whether communication link monitoring notice of shielding harness of the performed part pending operation of IRP Manager.Part is hung up the operation of northbound interface and is initiated to IRP Agent by IRP Manager, when IRP Agent allows operation that the part of IRP Manager hangs up, return one by IRP Agent to IRP Manager and hang up Id (suspensionId), show the executed hang-up, and inform that it is performed the object's position of hang-up.
The present invention is this function operations of a removing of definition on northbound interface again, and part that this operation called after is removed northbound interface is hung up (removePatiallySuspendItfN), and this operation need be carried and be hung up Id, shows to remove which part pending operation.
The present invention also need define two notices on northbound interface.The part of first notice called after notice northbound interface is hung up (notePatialSuspensionItfN), IRP Agent utilize first notice inform relevant IRP Manager successful execution part pending operation, this notice comprises all input parameters of part pending operation and hangs up Id; Second notice is the removing (noteRemovePatialSuspensionItfN) that called after notice northbound interface is partly hung up, IRP Agent utilize second notice inform relevant IRP Manager its successful execution remove the part pending operation, this notice will comprise hangs up Id.All relevant IRP Manager refer generally to subscribe to notice from being suspended object, have perhaps carried out the IRP Manager of certain operation awaits response.
After inner certain object of IRP Agent is adopted the northbound interface part operation to hang up by an IRP Manager, this object among the IRP Agent just no longer accept to remove is removed other operations the operation that northbound interface partly hangs up, and this object also no longer sends and removes the part hang-up of notifying northbound interface and notify other non-link communication monitor for notifications two notices of removing that northbound interface partly hangs up.Whether whether this object sends the link communication monitor for notifications will contain communication link supervision permission flag in the operation according to received part hang-up northbound interface, if having then this object transmission link communication monitor for notifications; If not then this object does not send the link communication monitor for notifications.Received operation during hanging up directly abandons with other notices that produced IRP Agent to this object, but preserves the notice relevant with daily record.
Often there are a plurality of operating maintenance terminals at concrete Operation and Maintenance environment, the corresponding IRP Manager of each operating maintenance terminal, this just makes the corresponding a plurality of IRPManager of an IRP Agent.If this moment, an IRP Manager carried out the part pending operation by northbound interface to certain object of IRP Agent, IRP Agent should send the notice northbound interface to all relevant IRPManager and partly hang up information so; If an IRP Manager has carried out the releasing pending operation by northbound interface to certain object of IRP Agent, IRPAgent should send the removing information that the notice northbound interface is partly hung up to all relevant IRP Manager so.
These two operations of removing and two notices that part is hung up, the notice northbound interface is partly hung up that part is hung up the operation of northbound interface, the operation of removing the part hang-up of northbound interface, notice northbound interface are core of the present invention, IRP Manager and IRP Agent utilize these two operations and these two notices, finish inner certain object that needs interim Operation and Maintenance of IRP Agent under the situation that does not influence the normal operation of other objects, operate on it maintenance.
When certain object needs interim Operation and Maintenance in the IRP Agent, hang up the northbound interface operation by the IRP Manager that carries out Operation and Maintenance by part and partly hang up request to this IRP Agent transmission northbound interface, IRP Agent according to part hang up that the manager quotes in the northbound interface operation, basic management object instance, object range and communication link monitor that it is the request of being initiated by which IRP Manage that permission flag four class parameters are determined, need to hang up which object, the subobject that whether relates to this object, whether real time monitoring communication link and send related announcement; After IRPAgent hangs up the object of appointment, utilize the part of notice northbound interface to hang up the IRP Manager that notify all to be correlated with; IRP Agent carries out Operation and Maintenance when being suspended object, as receives the part pending operation request of removing northbound interface, removes the hang-up to this object, and all relevant IRP Manager are notified in the removing that utilizes the notice northbound interface partly to hang up.
The northbound interface of the present invention between EMS and NMS uses the interface section to hang up mechanism, the minimum particle size of hanging up is an object, only real execution of the object of the interim Operation and Maintenance of needs hung up, the operation of other objects and notice behavior are unaffected, allow in case of necessity all subobjects of an object are carried out hang-up, can also select whether to hang up in the lump together with the communication link monitor for notifications.When an IRP Manager successfully triggered part pending operation to certain object, the IRP Agent that this object belongs to need notify other relevant IRP Manager, allows relevant IRPManager know the present residing state of this object; When an irrelevant IRP Manager attempted to operate the object that is suspended, IRP Agent gave this IRPManager with the state notifying of this object, refuses its operation requests with this.
Be the clearer understanding the present invention of energy, now be described in detail with specific embodiment.
See also Fig. 5, be the system block diagram of network management system, there are a plurality of operating maintenance terminals in network management system, and each operating maintenance terminal links to each other with NMS, and NMS connects EMS1, EMS2 and network element C, and EMS1 links to each other with network element B with network element A, and EMS2 links to each other with network element D.The all corresponding IRP Manager of each operating maintenance terminal, EMS1 and EMS2 are equivalent to IRP Agent, and a plurality of IRP Manager can manage EMS1 and EMS2.Network element A can be radio network controller (RNC), and EMS1 can be the operation maintenance center (OMC-R) of RNC.Fig. 6 is the internal object structural representation of OMC-R, wherein be connected with other objects and BTS management object (NodeBSiteManager) under the parent object in the OMC-R, be connected with Node B (NodeB) and base station transceiver (Transceiver) object under the BTS management object, be connected with under the Transceiver object and comprise Transceiver 1 at interior a plurality of Transceiver examples.In system's operation process, if the base station transceiver of Node B (Transceiver) object needs to safeguard, corresponding with it is Transceiver 1 object instance, so during safeguarding, network management system is desirably in northbound interface and hangs up this object instance, hang up principle according to part of the present invention, when hanging up the Transceiver1 object instance, other objects among the OMC-R are unaffected, Fig. 7 hangs up the internal object state diagram schematic diagram of back OMC-R for the part interface, wherein the expression Transceiver1 object of grey is in suspended state, can not receive the operation of other IRP Manager, send subscribe message can not for other IRP Manager, inner other objects of OMC-R then can receive the operation of IRP Manager, send subscribe message, the influence that not be suspended by the Transceiver1 object also can for other IRP Manager.
If the IRP Manager1 part hang-up of Transceiver1 object instance in EMS1 initiates Fig. 6 by 1 correspondence of operating maintenance terminal among Fig. 5 is asked, see also Fig. 8, be the flow chart that interface section of the present invention is hung up, as shown in the figure, this method detailed process comprises:
1, IRP Manager1 sends part to IRP Agent and hangs up solicited message, carries in the solicited message that the manager quotes, basic management object instance, object range and communication link monitor permission flag four class parameters;
2, IRP Agent checks the object range parameter, judges whether to relate to the hang-up of its subobject, if relate to its subobject, then carries out all subobjects that need when hanging up to be suspended object and hangs up; If do not relate to subobject, do not relate to the subobject that is suspended object when then carrying out hang-up; IRP Agent determines the object instance that needs are hung up according to basic management object instance parameter;
3, IRP Agent according to the basic management object instance and whether needs hang up the object that the information check needs of subobject hang up and whether be suspended, if the object that has been suspended is arranged, IRP Agent structure produces the list object of conflict; If do not continue to carry out next step;
4, IRP Agent checks that communication link monitors permission flag, determines whether to implement the monitor communication link according to this sign, is then to implement the monitor communication link and send related announcement to relevant IRP Manager; Otherwise do not implement the monitor communication link and send related announcement to relevant IRPManager;
5, IRP Agent carries out the object of appointment and hangs up, and return to IRP Manager1 and to hang up Id, show the position that this object is hung up, if IRP Agent has constructed the list object that produces conflict, then IRP Agent also needs this conflict tabulation is returned to IRP Manager1, informs that the operator clashes;
6, IRP Agent sends the announcement information of successful execution part pending operations to all relevant IRP Manager, and this announcement information carries the Id of hang-up, hangs up the parameter that object instance number and IRP Manager1 solicited message are carried;
Whether 7, IRP Agent promptly carries out Operation and Maintenance to this object according to the state of the object of the Operation and Maintenance requirement renewal hang-up of inside, need real time scan to have operation requests information to arrive simultaneously;
When 8, receiving certain operation requests information, judge at first whether this request is to remove the removing northbound interface part pending operation information that is suspended object instance, be that then IRP Agent execution is to the releasing of the part pending operation of this object, and notify all relevant IRPManager immediately, carry the Id of hang-up in the announcement information; Not then further to judge whether it is new part suspending command;
9, be new part suspending command, then need new part of initialization to hang up flow process, and turned back to for the 7th step; Not new part suspending command, then judge the whether autocorrelative IRP Manager in source of this operation requests;
10, not the autocorrelative IRP Manager in source, then notify this IRP Manager, carry the Id of hang-up and the parameter that the IRPManager1 solicited message is carried in the announcement information, refuse its operation requests with this according to the 6th current state that goes on foot the object that to be suspended; Be the operation requests of the autocorrelative IRP Manager in source, then no longer send such notification, turn back to above-mentioned the 7th step.
Method of the present invention is done other interfaces that change promptly may be used on network management system slightly; the interface between network element and the Element management system for example; and by other standardization bodies regulation or self-defining webmaster model in; therefore; anyly be familiar with this operator; in not breaking away from spirit of the present invention and category, change of being done and retouching are all belonging to protection range of the present invention.
