Description

Generate the method for incremental data based on serial number

Technical field

The present invention relates to required synchrodata generation method in a kind of network management system, relate in particular to required synchrodata generation method in the 3GPP network management system.

Background technology

Third generation partner program (3rd Generation Partnership Project, 3GPP) in, the interface between Element management system (EMS) and the network element (NE) is called Inf-S (south orientation) interface.Interface between network management system (nms) and the Element management system (EMS) is called Inf-N (north orientation) interface.

In order to guarantee effective management of communication network, the data between EMS and the NE need be consistent.In existing systems, the configuration data method of synchronization between EMS and the NE is divided into all data method of synchronization and the incremental data method of synchronization, and the total data method of synchronization and increment are two independently processes synchronously.Incremental data synchronously in, present way is at EMS here, go up certainly subsynchronous after, the data of operating personnel's off-line arrangement are all got off by data-base recording.But do the dependence that has all multimodes like this, be unable to do without the trigger of database, synchronously, also need to do the removing of vestige, the flow process complexity, in addition, a lot of business databases are general on the basic SQL statement, but the realization of trigger etc. is incompatible, therefore, present way makes troubles for the transplanting of software, and total data is synchronous and synchronous two flow processs of incremental data can't be unified, and like this, the attendant just needs oneself to judge whether total data, and still increment is synchronous synchronously, bring operation to go up the possibility of error, bring hidden danger to the network operation.

In order to guarantee effective management of communication network, the data between NMS and the EMS need be consistent.In existing systems, the configuration data method of synchronization between NMS and the EMS belongs to all data method of synchronization, i.e. after the configuration data of NMS initiation and EMS was synchronous, EMS reported NMS to configuration datas all in the management domain.The advantage of this mode is to realize simply can guaranteeing that the configuration data of NMS and EMS is consistent.But shortcoming is, has the situation of a large amount of configuration datas at EMS, and total data may cause the interface load of EMS and NMS and EMS overweight synchronously, triggers other problemses such as NMS or EMS system instability, communication disconnection, synchronization failure.

Industry has been recognized the defective of all data method of synchronization at present, in order to reduce interface load, in relevant OMC northbound interface standard, the synchronous demand of incremental data has been proposed, but still there is not the solution of determining, mainly be not have better incremental data generation method, if NMS tells EMS with all data back, finish the full comparison of initial data and form incremental data by EMS, the complexity of Ji Suaning, time cost will be very huge so, obviously can not effectively solve the quick generation of incremental data.

Summary of the invention

Technical problem solved by the invention provides a kind of method based on serial number generation incremental data, has reduced the data in synchronization amount, has alleviated the traffic load of interface.

Technical scheme is as follows:

The method that generates incremental data based on serial number comprises the steps:

(1) network element NE initiates synchronization request, sends whole serial numbers to Element management system EMS;

(2) serial number of described EMS traversal oneself and the serial number of described NE transmission compare and generate the incremental data that need notify described NE;

(3) described EMS issues NE with the serial number of deletion, and described NE receives will need the data deletion of deleting behind the serial number;

(4) for the data that increase and revise, need be synchronized to NE.

Further, serial number described in the step (1) is a sign, and each data object all has the serial number of distribution, and serial number is produced by EMS.

Further, this method takes a step forward in step (1) and comprises: NE initiates simultaneous operation, and when synchronous first, EMS sends whole serial numbers and corresponding data are carried out to NE synchronously.

Further, step (2) further comprises:

(21) after described EMS receives the serial number that all NE send over, the current serial number of described EMS traversal self;

(22) have corresponding serial number as described EMS, and EMS is when recording retouching operation, described EMS is to the data of the revising mark that makes an amendment.

Further, step (22) further comprises:

As the serial number of correspondence, and EMS indicates on the serial number of both sides when not having amendment record, in order to explanation EMS and this part data consistent of NE.

Further, step (22) afterwards step (2) also comprise:

(23) after described EMS had traveled through self current serial number, the serial number that described EMS traversal NE sends if serial number was not beaten sign, illustrated that these data delete;

(24) serial number of described EMS traversal self was not beaten sign as serial number, and then the data of this serial number correspondence increase.

The present invention is specially adapted to northbound interface and southbound interface in the 3GPP network management system, realizes synchronously by generating the required incremental data of synchrodata.The present invention generates incremental data fast by serial number, the employing incremental data is synchronous, only the configuration data that changes (comprise newly-increased, deletion, revise) is carried out synchronously, in long-term maintenance management, reduce the data in synchronization amount, alleviated the traffic load of interface.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.

With reference to Fig. 1, Fig. 2 and Fig. 3 the processing procedure of southbound interface is described in detail.

As shown in Figure 1,1,2,5 of NE this side ..., M represents serial number, the corresponding corresponding data of each serial number, and the serial number of NE is that EMS distributes transmission.EMS this

side

1,2,6 ..., M represents serial number, the corresponding corresponding data of each serial number.

As shown in Figure 2, the processing procedure of southbound interface is as follows:

1, NE initiates simultaneous operation to EMS.

2, first synchronously the time, EMS sends total data to NE, and the data that send whole serial numbers and correspondence are carried out synchronously.

3, NE initiates synchronization request to EMS.

4, NE sends own all serial numbers to EMS.

5, the serial number of the serial number of EMS traversal oneself and NE transmission compares, and generates the data of increment.

6, EMS issues NE with the serial number of deletion, and NE receives will need the data deletion of deleting behind the serial number.

7, EMS sends the data that increase and revise, and sends the serial number that increases simultaneously, and NE increases data and revises data according to the information that receives.

As shown in Figure 3, EMS compares, and the detailed process of the data of generation increment is as follows:

After step S301:EMS receives the serial number that all NE send over, the current serial number of EMS traversal self.

Step S302:EMS judges in current self the serial number whether amendment record is arranged.

Step S303: when there is corresponding serial number in EMS, and EMS is when recording retouching operation, to the data of the revising mark that makes an amendment.Serial number 2 that for example can the mark correspondence is BLUE, and the data of representing this serial number correspondence are through revising.

Step S304: when there is corresponding serial number in EMS, and when EMS does not have amendment record, on the serial number of both sides, indicate, in order to explanation EMS and this part data consistent of NE, otherwise just explanation is the data that need reissue, and the data type that need reissue can be to increase, delete, revise.

After step S305:EMS has traveled through self current serial number, the serial number that EMS traversal NE sends.

Step S306:EMS judges whether contain the data that do not have mark will in the data that NE sends over.

If serial number was not beaten sign, illustrate that these data delete, and stamp sign for the serial number of this deleted data.For example,, stamp sign RED then for serial number 5, represent that the data of these serial number 5 correspondences are deleted datas if the data of serial number 5 correspondences are deleted datas.

The serial number of step S307:EMS traversal self.

Step S308:EMS has judged whether that serial number does not have mark will.

Step S309: if there is serial number not beaten sign among the EMS, then the data of this serial number correspondence increase.EMS stamps sign on the serial number that increases, for example, when the data of serial number 6 correspondences are the data that increase newly, mark YE on serial number 6 then.

With reference to Fig. 4, Fig. 5 and Fig. 6 the processing procedure of northbound interface is described in detail.

As shown in Figure 4,1,2,5 of NMS this side ..., M represents serial number, the corresponding corresponding data of each serial number, and the serial number of NMS is that EMS distributes transmission.EMS this

side

By top process, EMS has generated the incremental data that needs notice NE fast, and for the data of deletion, EMS is as long as send to NE to corresponding serial number, and NE deletes the data of these serial number correspondences.Data for increasing, revising need be synchronized to NE, and load mode is not limited to any feasible method.At last, EMS sends to NE to newly-increased serial number.

Obviously, when NE does not have data, be exactly that total data is synchronous.

As shown in Figure 5, the processing procedure of southbound interface is as follows:

1, NMS initiates simultaneous operation to EMS.

2, first synchronously the time, EMS sends total data to NMS, and the data that send whole serial numbers and correspondence are carried out synchronously.

3, NMS initiates synchronization request to EMS.

4, NMS sends own all serial numbers to EMS.

5, the serial number of the serial number of EMS traversal oneself and NMS transmission compares, and generates the data of increment.

6, EMS issues NMS with the serial number of deletion, and NMS receives will need the data deletion of deleting behind the serial number.

7, EMS sends the data that increase and revise, and sends the serial number that increases simultaneously, and NMS increases data and revises data according to the information that receives.

As shown in Figure 6, EMS compares, and the detailed process of the data of generation increment is as follows:

After step S601:EMS receives the serial number that all NMS send over, the current serial number of EMS traversal self.

Step S602:EMS judges in self current serial number whether amendment record is arranged.

Step S603: when there is corresponding serial number in EMS, and EMS is when recording retouching operation, to the data of the revising mark that makes an amendment.Serial number 2 that for example can the mark correspondence is BLUE, and the data of representing this serial number correspondence are through revising.

Step S604: when EMS has corresponding serial number, and when EMS does not have amendment record, on the serial number of both sides, indicate, in order to explanation EMS and this part data consistent of NE, otherwise just explanation is the data that need reissue, and the data type that need reissue can be to increase, delete, revise.

After step S605:EMS has traveled through self current serial number, the serial number that EMS traversal NMS sends.

Step S606:EMS judges the data whether mark will is arranged in the data that NMS sends over.

If serial number was not beaten sign, illustrate that the data of this serial number correspondence are deleted, and stamp sign for the serial number of this deleted data.For example,, stamp sign RED then for serial number 5, represent that the data of these serial number 5 correspondences are deleted datas if the data of serial number 5 correspondences are deleted datas.

The serial number of step S607:EMS traversal self.

Step S608:EMS has judged whether that serial number does not have mark will.

Step S609: if there is serial number not beaten sign among the EMS, then the data of this serial number correspondence increase.EMS stamps sign on the serial number that increases, for example, when the data of serial number 6 correspondences are the data that increase newly, mark YE on serial number 6 then.

By top process, EMS has generated the incremental data that needs notice NMS fast, and for the data of deletion, EMS is as long as send to NMS to corresponding serial number, and NMS deletes the data of these serial number correspondences.Data for increasing, revising need be synchronized to NMS, and load mode is not limited to any feasible method.At last, EMS sends to NMS to newly-increased serial number.
