Abstract
The invention relates to a wireless network mass data storage method which comprises: each network element data server, according to the preset integration strategy, processes the original data captured from the corresponding network element and stores the data, and reduces the data to the secondary data under the premise of guaranteeing the necessary analytic information; each network element data server, according to the preset data acquisition strategy, centralizes the data required for the statistics in a data server from the secondary data stored therein, and sends the data to a centralized data server for storage via the network. The method constructs the hierarchical data storage, and according to the service rule and analysis requirement, extracts the mass original data at different hierarchies on the premise of guaranteeing the necessary analytic information, to form the hierarchical data. Additionally, the method can prolong the storage period of secondary data hierarchy by reducing the storage period of the original data, that is, the method can meet not only the requirement of original data query but also the statistical requirement for routine maintenance and centralized control, and provide strong support for the field network maintenance and optimization.
Description
Technical field

Embodiment
At first, core of the present invention is described:
Adopt (one) data integrated strategy and (two) Dynamic Data Acquiring strategy to eliminate data volume on a large scale, guarantee active data information simultaneously, satisfy the analyze demands of field network situation.
(1) data integrated strategy
1. the original data object granularity is simplified
Granularity is simplified and can data volume be simplified significantly, keeps the information that needs simultaneously, several optimal way below main the existence:
● the deletion redundant field,, there be " sum, successfully number, failure number " such as switching in the object, can boil down to " successfully number, failure number ".Also has some other field that can not use.
● packed data is preserved type, such as the attribute use INT of part object, and can boil down to SMALLINT according to actual conditions.
● the compression type of service, there are 9 kinds such as the sub-district registered type, can boil down to 3 kinds etc.
● the index compression: for the complicated index of part, computing formula is very complicated, needs usually to use a plurality of original data object, can calculate these indexs and preserve in advance, and relevant original data object does not just need to preserve.
2. the original data object number is simplified
The original data object number is simplified to be divided into and is removed and the merging dual mode, and removal just is meant directly removes the unwanted original data object of part in secondary data; Merging just is meant merges into a secondary data object with the part original data object, thereby merge the original data object repeated content, keep exclusive information, reach the requirement that reduces data space, such as objects such as calling, switching, release, resource are merged into several objects, location that each object is shared and index field have just obtained saving.
(2) Dynamic Data Acquiring
Adopt the means of dynamic adjusting data acquisition time section, that is: safeguard angle from real network, the user might not be concerned about the data of each time period of every day, usually only pay close attention to data between 8:00～20:00 such as part operator, the probability that all the other data of 12 hours are seen is very little, also be nearly to have that 1 half data do not have actual using, certainly for different users, it pays close attention to the time period is different, therefore this part can provide a kind of mechanism more flexibly, can be by the own definition of data acquisition time of user section.Can strengthen the utilization and the processing of valid data greatly.
In second step, further specify characteristics of the present invention:
(1) storage framework
As shown in Figure 2, the network element data server is preserved initial data and ground floor secondary data, intensive data server and preliminary data server thereof are preserved second layer secondary data, promptly as required the deposit level of mass data on different server carried out unified planning, described second layer secondary data also comprises isomeric data.
(2) data hierarchy is handled
As shown in Figure 3, mainly comprise data and integrate, data acquisition, 3 functional modules of data management are complied with strategy execution separately.
(3) dynamic adjusting data is deposited granularity
From on-site actual situations, the base station controller number that centralized servers is managed does not wait between 2～40, and according to the configuration difference of junior office NE type, presents very big difference on data volume.So can realize a kind of preservation mechanism of data more flexibly.Promptly the disposal ability with database server is a thresholding, in conjunction with the NE quantity and the NE type of actual loading.The granularity and the time limit of coming dynamic adjusting data to preserve.
Such as: when 40 base station controllers of centralized services management, may can only preserve 3 days 60 minutes granularity datas, half a year the sky granularity data, but when centralized servers is only managed 2 base station controllers, can preserve 30 days 60 minutes granularity datas, 1 year sky granularity data.As seen dynamic historical deposit data strategy can very relevantly satisfy user's demand.
In the 3rd step, describe the present invention in detail in conjunction with idiographic flow:
On the network element server, can periodically handle initial data according to the integrated strategy that configures in advance, the magnanimity initial data is converted into secondary data, then can be according to the data acquisition strategy, according to the situation of edition compatibility, the secondary data that needs is copied to the centralized maintenance center, under abnormal conditions, can carry out the data filling mining, guarantee the integrality that data are duplicated.On OMM and NMC, all there is relevant data management module original historical data and secondary historical data to be safeguarded, thereby finishes the storage by different level of mass data according to the maintenance strategy that configures.Specifically see accompanying drawing 4, wherein:
Data are integrated: finish the conversion of initial data to secondary data;
Strategy is set: comprise the setting and the maintenance of data integrated strategy, acquisition strategies, deletion strategy;
Data acquisition: finish the copy or the migration of secondary data;
Data management: carry out the maintenance of initial data, secondary data.
At last, with further aid illustration of actual physical structure of the present invention:
As shown in Figure 5, NMC is the intensive data server, and OMM is a data server, and the data on NMC and the OMM distribute as follows:
1. in the present embodiment, deposit secondary data on the NMC server, deposit initial data and secondary data on the OMM server.
2.OMM can regularly be integrated into secondary data to initial data according to the acquisition granularity and integrated strategy on the server, after finishing, can initiatively send to the NMC server to secondary data.
3. on the OMM server, initial data only kept 7 days, and secondary data kept 30 days, and secondary data kept 7～180 days on the NMC server.
4.NMC on statistical analysis based on historical trend and pinpointing the problems, the user visits initial data if desired on NMC, can directly visit the OMM database.
5. keeping under the situation of same analytical information, 1/10th before the storage data volume is reduced to, analysis efficiency has improved 20 times, implements in product at present.
