Description
Technical field
The present invention relates to the network management technology of telecommunications network, relate in particular to the method for inspection of mobile radio communication Network Element Layer north direction interface data integrity.
Background technology
Be the needs of develop rapidly that adapts to the telecommunications network technology and the new business of communicating by letter that increases day by day, standardization department of international telecommunication union telecommunication (ITU-T) has proposed telecommunications network is carried out the telecommunication management network (TMN) of unified integrated maintenance management.TMN is an organized network, is a kind of comprehensive means of collecting, handle, transmit and storing relevant telecommunications network maintenance, operation and management information, and TMN plays supporting role for the managing telecommunications net.TMN can provide a series of management function, and can make between various types of operating systems and communicate contact by standard interface, can also make between operating system and the telecommunications network and also can communicate contact by standard interface.
Yet, open day by day along with telecommunication market, various network elements, the management information relevant with telecommunication service and the management entity of finishing the TMN function managed logically and physically all are distribution, and are among the dynamic change.Various management application based on traditional TMN standard have shown certain limitation.And be accompanied by the increasingly mature of network technology this moment, and the management mode of telecommunications network needs to open to having day by day, the network management technology direction of distributed treatment and interoperability develops.
In recent years, many technical standard and standards have been emerged in the world about this respect, wherein, northbound interface (NI, Northbound Interface) the general object agent architecture (CORBA) in is the most representative, the CORBA structure is ripe gradually through ten years development, and successfully has been used in some large software systems.Northbound interface is meant lower layer entities to its general designation of a kind of interface of uploading data of higher layer entities assembly more, with it the interface that direction of transfer is opposite be called as southbound interface (SI, SouthboundInterface).CORBA is application software architecture and the object technology standard that is proposed by OMG (OMG), its core is standard set language, interface and agreement, to support the interoperability between isomery distribution applications program and to be independent of platform and the object reuse of programming language.Because the CORBA self characteristics, adopting CORBA technology and TMN to combine becomes the new direction of present network management technology development.
Based on the northbound interface of CORBA, be usually located between network layer network management center (NMC) and network layer webmaster or the sub-network layer webmaster among the TMN, for upper layer NMS provides data access interface, finish and lower floor's webmaster between mutual.TMN provides a kind of framework for telecommunication administration, by introducing the universal network model of management, adopts general information model and standard interface, realizes the general management to various diverse equipment.Network management interface plays an important role between network management system and network element, is the source, basis of network management information.
Present mobile communications network management adopts group more and economizes two-stage centralized management system, group's mobile communication network management system is NMC, be responsible for complete or collected works are rolled into a ball concentrated, the unified management of network, managing each provincial mobile communication network management system is Network Element Layer network management center (POMC); POMC is responsible for the concentrating of this provincial mobile communication network, unified management, and the management Element management system that provides of each equipment vendor inside the province is facility network tube hub (OMC); OMC provides the Operation and Maintenance that meet mobile radio communication pipe standards interface to last to POMC to following managed network element (NE) equipment.NE equipment is the general designation of concrete communication facilities or logic entity in the network, specifically finger base station (BS), base station controller (BSC), mobile switching centre (MSC) etc. in mobile radio communication.
According to the requirement of present TMN, POMC docks with NMC, and Network Element Layer need provide northbound interface.Because POMC adopts hierarchy mostly at present, general POMC is divided into provincial network management center, OMC double-layer structure; Perhaps be divided into POMC, local network management center (LOMC), OMC three-decker.Wherein, OMC is responsible for the collection of network element data, and POMC is responsible for docking with upper strata NMC.
Fig. 1 is a network management system form and function synoptic diagram in the prior art, as shown in Figure 1, the core of network management system can be divided into Network Element Layer, data analysis layer, application service layer on function, wherein, Network Element Layer be responsible for gathering collection network O﹠M information, assign tasks such as webmaster instruction; Data analysis layer is handled interactive information, the acquisition of information with Network Element Layer on the one hand, and the information that adaptive on the other hand Network Element Layer will report reports after through unified performance adaptation processing; The NM server system of application service layer is based on the distributed software structure of CORBA bus, and the functions such as configuration management, performance management, fault management, safety management, log management and remote operation maintaining that equipment is concentrated are provided.The processing of the information data that reports for Network Element Layer can be divided into image data, deal with data and three mutual levels of application data, by between these three layers finish alternately to network operation situation obtaining and to the manipulation control of the network equipment.Wherein, image data is meant that OMC writes the performance data of dissimilar equipment the process of network management system raw data base, adopt unified standard interface between data acquisition and data processing, dissimilar collection services is all passed through this interface data transfer is arrived data analysis layer; Deal with data is meant different data contents is converted to unified format, and it is kept at process in the unitized database; Application data is to realize the process of functions such as configuration management, performance management, safety management, fault management and resource management.
In the existing network administrative skill, network layer data reports by Network Element Layer and obtains.The basis that north direction interface data calculates in the prior art is a performance data, and performance data derives from data acquisition, and image data is positioned at the OMC side at present, and northbound interface is positioned at the POMC side, so acquisition interface and deal with data are separated from each other.Owing to there is not association between north direction interface data and the data acquisition, this has just caused north direction interface data to have the defective of failing to report, misrepresenting deliberately, and prior art can't be prevented the generation of this defective and defective can't find the reason of failing to report, misrepresenting deliberately when taking place.
Summary of the invention

Embodiment
With reference to the accompanying drawings embodiments of the present invention are described.
Core concept of the present invention is: by setting up getting in touch of Network Element Layer data acquisition and northbound interface, data collection result and POMC north direction interface data are compared and analyzed, can know the reason that north direction interface data is failed to report and misrepresented deliberately, thereby take measures to avoid the generation failing to report and misrepresent deliberately, to guarantee the integrality of north direction interface data.
Fig. 2 is the realization principle schematic of the inventive method, and as shown in Figure 2, the present invention realizes that the flow process of north direction interface data integrity check comprises:
Step S1001, OMC gather various original performance data such as voice are exhaled, paging, registration, release from the base station, and with various original performance data storage in raw data base separately.
Here, in actual applications, various original performance data are stored in the raw data base of each OMC with the form of table, the table of the various original performance data of storage can be called the original performance tables of data, can corresponding every class performance data set up different original performance tables of data respectively.
Step S1002, construct a hash table (Hash Table), mode with hash function mapping (Hash Map) is classified the original performance data according to performance object, the outcome record of each performance object data that OMC is collected is got off, and the data acquisition object information that obtains is stored in the computer hosting.
Here, collection result information is stored in internal memory with the form of Hash Table, and wherein storage is the collection result information of each performance object, comprises whether collection is successful, the bar number of collection etc.
Step S1003, OMC calculates the CORBA index with various performance datas respectively according to algorithms of different.
The CORBA index here is meant the CORBA data that need report NMC, and the CORBA index is generally held in the calculator memory of carrying out computing function.The CORBA index is an example with BSC traffic performance data, comprises following: do not contain the channel assignment request number of times of switching and note calling service, the calling service channel allocation number of success that does not contain switching and note, call attempt number of times, call setup number of success etc.
Step S1004, CORBA adapter on the POMC is that Hash Table analyzes to the data acquisition result of step S1002 gained, whether wrong in the collection result in order to judge, whether collection result complete, gather information such as whether success, pick-up slip number, obtains corresponding analysis result.
Step S1005, the CORBA adapter on the POMC is analyzed the CORBA achievement data that step S1003 obtains.
Here, the described CORBA achievement data is analyzed mainly is that abnormal data is analyzed, and then compare with analysis result that step S1004 obtains, whether the data acquiring and recording of the collection result of original performance tables of data normally is whether whether data acquiring and recording have omission, data acquiring and recording complete as can be known, thereby can draw the incidence relation of the unusual and institute's image data of CORBA index.Here, described abnormal data is meant without any collection result (NULL) or exists the result should not be for 0 but being 0 situation.
Give an example, whether test of hypothesis index attCalls is empty, the original performance tables of data relevant with attCalls is R GlobalVoiceCallOrigin, R GlobalVoiceCallPaging, whether the data acquiring and recording that can contrast in these two tables is normal, thereby can draw the incidence relation between the unusual and institute's image data of CORBA index.Detailed process is: if this moment, the attCalls index was sky, can check respectively then whether the collection result record is complete in R_GlobalVoiceCallOrigin, the R_GlobalVoiceCallPaging table, if it is imperfect, think that then attCalls is empty, thereby index incidence relation unusual and institute's image data is determined.Here, whether whether complete each data item that is meant that certain bar writes down in the table is complete.
Step S1006, POMC report integrated reference point (IRP) after the CORBA data are assembled.
In this step, report IRP after why the CORBA data being assembled and be because: after the assembling of CORBA data finishes is the big Hash Map of a multilayer, does not meet the CORBA data standard.IRP the effect here is that Hash Map data are carried out format conversion, makes it to meet CORBA index standard, afterwards the data after the standard is reported each functional subsystem of NMC side, and IRP is usually located at the POMC side.
Step S1007, the NMC webmaster obtains meeting CORBA index specification data by the IRP of corba interface, as the normal data of being convenient to utilize Computer Processing for the various management function subsystems of application layer.
Whether by above checking procedure, can know has abnormal data, and knows the relation of abnormal data and data acquisition results abnormity.Like this, just can determine whether to continue reported data and give IRP,, then can when gathering, carry out filling mining next time, therefore, avoid the phenomenon of failing to report, misrepresent deliberately of north direction interface data to take place if do not report IRP.
More than be overall realization principle and process of the inventive method, the process of failing to report, misrepresent deliberately check at OMC data system Information Monitoring process and POMC north direction interface data respectively is further detailed below.
Fig. 3 is an OMC data system Information Monitoring process flow diagram, and the flow process of described data system Information Monitoring is step S1001 and the described process of step S1002 among Fig. 2, and concrete acquisition step is as follows:
Step T001, OMC connect each base station, and the data acquisition timer that connects back OMC self picks up counting.
Herein, the timer work period is called the acquisition granularity again, can be made as required 15 minutes, 30 minutes, 1 hour etc., and performance data cycle and the acquisition granularity that equipment reports are consistent.
The data of performance objects such as step T002, OMC rise the voice of base station and exhale, paging, registration, release are carried out circle collection.
Step T003, the connection status between record OMC and each base station comprises: normal connection, off-state.
Step T004, the information bar number of record acquisition performance object and time information corresponding when producing this information.
Step T005, the abnormal information that record and storage of collected arrive.
Here, described abnormal information is meant in the program because the abnormal information that produces under the situations such as database manipulation is unusual, network connects unusually, program exception.
Step T006 when collection period finishes, judges whether also have this moment the data of performance object not gather, if having, and execution in step T002 then; If no, execution in step T007 then.
Step T007 is kept at the data acquisition result in the calculator memory of OMC side with Hash Table form, and the information that collects is reported the POMC processing.
Step T008, OMC discharges shared system resource.
Raw data and collection result information by above-mentioned steps obtains calculate the CORBA index by OMC respectively with various performance datas, so that report NMC by POMC more as required.
Fig. 4 fails to report, misrepresents deliberately inspection process figure for performance object table data of the present invention, describedly fails to report, the process of misrepresenting deliberately is step S1004 in the corresponding diagram 2～process that step S1006 describes, and its Detailed Inspection step is as follows:
Step P001, POMC call the Java enterprise handle (EJB, Enterprise JavaBeans) of each OMC, by the data channel of communication link, set up and being connected of the database of network element side storage of collected object information.
Herein, described EJB is the part of J2EE (Java 2 Enterprise Edition), it has defined a standard that is used to develop based on enterprise's multiple utility program of assembly, EJB is deployed on the OMC, POMC operates the database on the OMC by EJB, and following steps are carried out the flow process of EJB by OMC.
Step P002, the data table name of raw data, acquisition time, grab type, pick-up slip digital section in the collection result information table in the described database of extraction step P001, structure chained list 1; Accordingly, the data structure of chained list 1 each chained list node comprises data table name, acquisition time, grab type, several four fields of pick-up slip at least.
Step P003, with the information that step P002 extracts, promptly data table name, acquisition time, grab type, pick-up slip number are put into chained list 1.
Step P004, by structural texture query statement (SQL), each chained list node in the traversal chained list 1 obtains the actual final data time that meets the CORBA index.
Here, the described final data time is meant by carrying out the nearest time of performance data that SQL statement obtains.
Step P005 judges whether acquisition time and final data time is consistent, if consistent, then goes to step P004; If acquisition time and final data time are inconsistent, then execution in step P006.
In this step, because the structure difference of various CORBA data, so need finish decision operation by the operation program corresponding with different structure.
Step P006, structure chained list 2, its data structure is consistent with chained list 1 structure, and each chained list node comprises data table name, acquisition time, grab type, several four fields of pick-up slip, the time among the step P005 is contrasted inconsistent list item record in the chained list 2.
In this step, also can represent acquisition time and inconsistent situation of final data time by increase label manner in chained list 1, the table that increases after identifying is called chained list 2.
Step P007 judges whether chained list 1 has traveled through, if do not traveled through, then returns P004 and continues to carry out SQL statement; If traveled through, execution in step P008 then.
Step P008, by carrying out the SQL statement of structure, each chained list node in the traversal chained list 2 is according to the acquisition time in the final data time renewal collection result information table that has obtained.
By upgrading the acquisition time that writes down in the collection result information table, the data that like this can filling mining when gathering next time do not report.
Step P009 promptly according to the data table name, upgrades the data acquisition state among the Hash Table according to Hash Table key word.
Step P010 according to the contrast successively different writing times that constantly are recorded in the chained list 2, upgrades the acquisition and recording in the chained list 2; When final data time ratio acquisition time occurring during evening, illustrate that this granularity data is incomplete.
Granularity data is not meant entirely that some performance table one granularities normally report 200 records, but has only reported 150 for some reason, and it is incomplete that just be called granularity data this moment, and need the data of this granularity of deletion this moment, gathers again in next collection point.
Step P01l judges whether chained list 2 has traveled through, if do not traveled through, then returns step P008, continues traversal chained list 2, upgrades the acquisition time in the acquisition tables; If traveled through, execution in step P012 then.
Step P012 finishes this checkout procedure, discharges the resource of absorb.
Because acquisition time upgrades after this granularity data collection finishes, granularity data is meant the performance that reports in the collection period, be relatively more fixing generally for an acquisition target, at each performance object, the data of a collection result information table report and finish, just upgrade the acquisition time of collection result information table record, by relatively acquisition time and the difference of final data time, can check out some granularity datas to report incomplete situation, thereby guarantee the integrality that data report.
So far, the method for inspection of leaking, misrepresenting deliberately for north direction interface data of the present invention is a complete process.
The above is an exemplary embodiments of the present invention only, is not to be used to limit protection scope of the present invention.
