A kind ofly in network management system, realize reverse synchronous method
Technical field
The present invention relates to the network management system technical field, be meant a kind of reverse synchronous method that in network management system, realizes especially.
Background technology
In the network management framework of 3GPP, there are three-decker, i.e. network element (NE, Network Element), Element management system (EMS more clearly, Element Management System) and network management system (NMS, Network Management System).3GPP has defined some integrated reference point (IRP, Integrated Reference Point) for EMS and NMS from the angle of logic, and these IRP show as IRPAgent and IRP Manager respectively on EMS and NMS.3GPP has clearly defined general utility functions IRP, basic configuration managing I RP (Basic CM IRP, Basic ConfigurationManagement IRP), performance management IRP (PM IRP, Performance Management IRP), entrance IRP (EP IRP, Entry Point IRP) and make mistakes and alarm management IRP (FM IRP, FaultManagement IRP) etc.
In present disclosed document, there has been the synchronous method of forward increment in network management system.But the forward increment synchronization mechanism of network management system only is applied among the basic configuration managing I RP usually at present.Referring to Fig. 1, it shows the connected mode between NMS and EMS and the NE.NMS generally adopts context A mode to link to each other with EMS, but it also can select to adopt context B mode directly to connect NE.Interface between NMS and EMS and the NE is the standard northbound interface.Network management system mainly utilize the synchronous method of forward increment finish configuration management IRP configuration data fast synchronously.When changing at the configuration data generation lightweight in the network management system, for example variation has taken place in the wireless parameter of certain sub-district object, can be apace to the network element loading data by the method that the forward increment is synchronous.
The current increment method of synchronization only is applied to the basic configuration managing I RP of network management system, and is based on object and carries out synchronously, and it has only solved from the network management system to the Element management system and the link transmission of network element there is no other purposes in addition.This scheme does not solve Element management system and the network element method to the network management system synchrodata, and promptly it does not solve the reverse synchronous problem in the network management system.
In present disclosed document, the reverse of network management system can only be realized by complete synchronous mode synchronously.Though this mode can realize reverse synchronous, but along with of the day by day enhancing of new generation network management system to the network element data monitoring requirements, depending merely on mechanism that reverse fully synchronous mode makes network management system obtain network element data goes data such as performance in the collection network and alarm must cause the busy and congested of reverse data channel, also will cause network management system to handle a large amount of repeating datas, and this significant adverse is in the efficient operation that guarantees network management system.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail again.
The invention provides a kind of reverse synchronous method, it mainly is synchronous in order to realize reverse increment.Be example with mistake and alarm management FMIRP below, specify implementation method of the present invention based on the 3GPP standard code.
For wrong and alarm management, the synchronous application scenarios of reverse increment mainly refers to reside in IRP Manager in higher level's network management system when the mistake of certain or some managed object classes and warning information are obtained in hope, and these information significantly change than not changing last time or not taking place.
Mistake and alarm management FMIRP are used for the alarm and the error message of Element management system or network element institute management object are passed to higher level's network management system.Below for sake of convenience, Element management system or network element are referred to as network element system.The leaching process that higher level's network management system utilizes the operation getAlarmList in the AlarmIRPOperations_1 interface that defines among the FMIRP to initiate alarm and error message.Both can extract the wrong and warning information of preserving among the Alarmlist in the network element system when higher level's network management system is initiated this operation, also can extract a class or the multiclass mistake and the warning information of a managed object class or a managed object class example.That is to say that higher level's network management system can provide and treat synchronizing information when carrying out this generic operation.
Reverse increment requires higher level's network management system to provide increment synchronous mark (DeltaFlag) and reference time point (ReferencePoint) to network element system synchronously when extracting alarm and error message.Network element system determines whether to adopt the increment information synchronization mechanism according to increment synchronous mark DeltaFlag.When specifically carrying out this type of increment information synchronization mechanism, alarm and error message that network element system need be compared current alarm of preserving and error message and be preserved at reference time point (ReferencePoint), and count an increment set based on alarm between this two times and error message content difference, then higher level's network management system is as a result of exported in this set.
Figure 2 shows that and use the synchronous realization principle schematic of reverse increment of the present invention.The upper left form of accompanying drawing has been expressed IRP Agent in alarm and the error message of certain reference time point in the AlarmList preservation, comprises from first to the N item and alarming.The upper right form of accompanying drawing has been expressed IRP Agent in alarm and the error message of current point in time in the AlarmList preservation, comprises from first to alarm of K item and the alarm of M item.For the purpose of difference, the upper right form utilization of accompanying drawing is filled texture table and shown the difference that current alarm and error message and reference time put: wherein variation has taken place in the state of first alarm and error message, the M item is new fully alarm and the error message that produces, the K+1 item no longer exists to N item alarm, and second to the alarm of K item with error message still exists and state does not become.Through incremental raio, meeting the difference content for the treatment of synchronizing information and should comprise that first alarm and the error message that change have taken place between current point in time and the reference time point, new fully M item alarm that produces and error message and the K+1 item that has no longer existed are alarmed to the N item.Afterwards, structure comprises the increment set of difference content, and this increment set is returned to higher level's network management system; Higher level's network management system realizes that according to the increment set that receives reverse increment is synchronous.
Above-mentioned difference content is made a general reference three partial informations, the content that (1) changes, and promptly last time point exists, but change has taken place at present; (2) Xin Zeng content, promptly last time point does not exist, but exists at present; (3) out-of-date content, promptly last time point exists, but disappears at present.This three category information abbreviates change, new and out-of-date information respectively as.
Above-mentioned reference time, some ReferencePoint both can be a concrete time value, also can be fully synchronously or the synchronous reference point of increment, for example last time performed synchronously.Certainly, for the IRP Agent in the Element management system (EMS), it will preserve a series of reference time point and alarm and error message during point in these at each different IRP Manager reference times.When adopting concrete time value as the reference temporal information, IRP Manager will adopt the granularity of itself and IRP Agent agreement to express, the principle of engagement of this granularity be according to the data storage capacities of IRP Agent itself and specific implementation to reverse increment synchronous require degree.
The above-mentioned increment set that comprises the difference content both can be made of the complete content of difference content list item, also can constitute by the sign field of difference content list item, that is to say, both managed object class that can the IRP Manager in the network management system is corresponding with IRP Agent in the Element management system was as the least unit of different information in the increment set, and also a list item among the AlarmList that the IRP Agent in the Element management system can be preserved is as its least unit.In general, mistake that AlarmList comprises and warning information list item comprise numerous fields, and it is the field AlarmId of sign property that a field is wherein arranged.IRPAgent will be provided with to judge it is only the sign field of list item to be added in the set or the complete content of list item is added in the set at structure according to its inside during above-mentioned set.This setting of IRP Agent will be synchronous to reverse increment according to specific implementation requirement.
Have again, when the IRP Agent in the network element system receives that the reverse increment of IRP Manager requires synchronously in the network management system, if the data of finding to comprise in the increment set of difference content have surpassed default thresholding M, for example the data in the set have surpassed the alarm of being stored at reference time point and 50% o'clock of misdata, and IRP Agent will refuse the synchronous requirement of reverse increment of IRP Manager.When finding the ReferencePoint time corresponding that IRPManager provides, IRP Agent exceeded the time granularity scope of arranging, when perhaps IRP Agent can't find the mistake of this reference time and warning information in database, IRP Agent will refuse the synchronous requirement of the reverse increment of IRP Manager.When being refused reverse increment by IRP Agent when synchronous, the unique channel that IRPManager obtains relevant information is to adopt complete data in synchronization transmission mechanism.
Figure 3 shows that and use a network management system of the present invention block diagram as a result.The interface that NMS is unified between Element management system and the network element is the standard northbound interface, and the interface between Element management system and each network element is a non-standard interface.Element management system or network element report reverse increment set by the standard northbound interface to network management system.For the network management system of 3G mobile communication system, network element among Fig. 3 mainly refers to the radio network controller in the wireless access network territory, the Mobile Switching Center Server of core network domain (MSC Server), Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) etc.; EMS among Fig. 3 refers to the operation maintenance center of wireless access network territory and core network domain; NMS among Fig. 3 then refers to the united net management system of 3G mobile communication system.
Figure 4 shows that the flow chart of an embodiment who uses the inventive method.This example is that example describes with wrong and alarm management still.
Step 401~402, the IRP Manager of higher level's network management system utilizes the getAlarmList operation of wrong and alarm management integrated reference point to initiate synchronization request to the IRP of Element management system Agent.Comprised in this request and treated synchronizing information, increment synchronous mark DeltaFlag and reference time point ReferencePoint.Wherein, treat that synchronizing information comprises classification and the managed object class for the treatment of synchronizing content, perhaps comprise classification and the managed object class example for the treatment of synchronizing content.
Step 403, IRP Agent judges according to increment synchronous mark DeltaFlag this is not promptly to judge whether comprise the increment synchronous mark in the synchronization request synchronously for increment, if not comprising the increment synchronous mark is that increment is synchronous just not, then execution in step 404, carry out according to complete reverse synchronous operation, if comprise the increment synchronous mark is exactly that increment is synchronous, and then execution in step 405.
Step 405~406, IRP Agent checks reference time point ReferencePoint, and judge this reference time point be concrete time or before reference point after subsynchronous, if the concrete time, then execution in step 407, if preceding reference point after subsynchronous, then execution in step 409.Before described subsynchronous can for increment synchronously also can be for fully synchronously.
Step 407, IRP Agent judges difference between current time and the reference time point whether within the time granularity scope that IRPAgent and IRP Manager arrange, if then execution in step 409, otherwise execution in step 408.
Step 408, the abnormal information of dishing out finishes.
Step 409~410, IRP Agent searches corresponding mistake and the warning information of described reference time point, and judges whether corresponding mistake and the warning information of this reference time point exists, if exist, then execution in step 412; Otherwise then execution in step 411.
Step 411, the IRP Agent abnormal information of dishing out, the getAlarmList operation of IRP Manager is returned with abnormal information and is follow-uply carried out according to synchronous operation fully.
Step 412, IRP Agent initialization are used to construct the set of wrong and warning information increment.
Step 413~415, IRP Agent judges it is only the sign field of list item to be added in the set or the complete content of list item is added in the set according to its internal configuration information, and finishes the structure of set.
Step 416, IRP Agent checks the scope of increment set institute coverage information, and judges whether the data that comprise in alarm and the set of error message content difference surpass default thresholding M, if then execution in step 411, otherwise execution in step 418.
Step 418, IRP Agent returns the increment synchronized result to IRP Manager, and the getAlarmList operation is normally returned.
Higher level's network management system realizes that according to the increment set that receives reverse increment is synchronous.Use method for synchronous of the present invention, not only can reduce the link transmission between IRP Agent and the IRP Manager, can also reduce IRP Agent newly-increased storage of uploading information such as warning information.
Though more than be example only with wrong and alarm management, method of the present invention equally can be by the applications such as performance management IRP of 3GPP standard code.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; and every based on the present invention do slightly change promptly may be used on by other normal structures regulation or self-defining webmaster model in, or use based on deriving of this type of and also should be considered as protection scope of the present invention.
