Embodiment
Below in conjunction with accompanying drawing concrete aforesaid way of the present invention is elaborated.
As shown in Figure 1, in one embodiment of the invention, the network element of data management mainly comprises base station, data buffering server, OMC.In Fig. 1, the base station is exemplary comprises 120,2 base stations 140,1 base station, N base station 160, obviously, the quantity of base station is not construed as limiting, its type also is not limited to not contain the distributed base station of base station controller (BSC), can be the centralized base station (managing a plurality of base stations under the BSC) that has BSC equally.A plurality of base stations are by the network switching equipment, and for example illustrated switch 180 carries out with data buffering server 200 alternately.
In this article, data management has implication widely, comprises data acquisition, transfer of data, data integration or the like various types of data processing forms.The data mode of being managed also is diversified, will be that example is described data management of the present invention with the performance data statistics of distributed base station below.The performance data of distributed base station mainly includes but not limited to: the equipment operation condition performance data of equipment manufacturers, performance datas such as the system resource of operator, telephone traffic, the quality of service data of third party service provider, content supplier, commercial provider, and data such as User Activity track, tendency hobby and market trend.
Data management, at first from the data acquisition of base station, this can be undertaken by the data acquisition module that is arranged on the base station.Concrete, in this routine performance data collection, the data acquisition module that claims the base station is the performance statistics agency.
Performance statistics agency is distributed in each base station, mainly be responsible for performance data collection, raw data file safeguard, to functions such as upload file of data buffering server and the maintenances of file buffering space.The performance statistics that resides on each base station is acted on behalf of concurrent working, according to P granularity (being that collection period is P) continuous collecting performance statistic.
Performance statistics agency is the collection period that the timer of P is determined the P granularity by duration is set, and create a raw data file at each collection period, then carry out performance data collection by function interface or message interface, carry out simple mathematical statistics, for example comprise computings such as maximizing, minimum value, mean value, summation, the performance data that collects in this collection period is written to the corresponding raw data file that this collection period is created.After timer P was overtime, a newly-built raw data file carried out the data acquisition of next collection period and writes file.
After writing of at least one raw data file finished, the performance statistics of each base station agency will transmit raw data file to data buffering server 200 by file transfer protocol (FTP).In the present embodiment, file transfer protocol (FTP) has adopted FTP (File Transfer Protocol, file transfer protocol (FTP)) agreement, certainly, also can use other file transfer protocol (FTP) to carry out the transmission of raw data file.Upload the network congestion that data cause in order to prevent each performance statistics agency burst simultaneously, in the present embodiment, postpone the regular hour difference between each performance statistics agency and carry out the transmission of raw data file, also be, each performance statistics agency adopts serial mode (to it should be noted that, may exist between two performance statistics agents and send at interval, also may not exist and send at interval, only need to guarantee not send simultaneously and get final product), according to predefined user name, password and IP address write raw data file separately the respective directories of data buffering server 200 successively.Order of transmission between each performance statistics agency is arbitrarily, for example can adopt send mode in turn, also can adopt the send mode that priority is set.Because the performance statistics agency adopts serial mode to carry out uploading of raw data file, therefore, a raw data file will be difficult to immediately uploading of (promptly finish at its collection period, the data that this cycle collects writing when finishing) usually, and have certain transmission lag.Can calculate the transmission lag time of the raw data file of each base station according to pre-defined algorithm, pre-defined algorithm can be provided with according to actual needs, for example, the transmitting time that can at first determine each raw data file needs 10 seconds, so, 1 base station 120 postpones transmission in 0 second, and 2 base stations 140 postpone transmission in 10 seconds, and 160 time-delays of N base station sent in 20 seconds.And in some cases, the also instant transmission lag time to each base station of pre-defined algorithm is adjusted, for example, when the transmission priority that is provided with some base station when (this will help better to monitor the performance condition of this base station), for example, 1 base station 120 has transmission priority, carry out file in 2 base stations 140 when uploading, 1 base station 120 need be carried out new file and be uploaded, then adjust 160 time-delays of N base station sent in 30 seconds, and 2 base stations, 140 files upload finish after, insert the new file of 1 base station 120 to upload, carry out the file of N base station 160 again and upload.In addition, performance statistics is acted on behalf of startup file and is uploaded, and the mode of can taking the initiative also can adopt passive mode.Active mode is that performance statistics was acted on behalf of according to its time of delay, after arriving time of delay, carries out file and uploads; Passive mode is a data buffering server 200 the file of a certain base station upload finish after, send file to predetermined next base station and upload indication.Dual mode, its pluses and minuses are respectively arranged, active mode has reduced the transinformation content between base station and the data buffering server, but a base station may occur and not upload file in the given time, startup file is uploaded and next base station is because delay time arrives, thereby file occurs and upload conflict; Otherwise passive mode then, though avoided file to upload the possibility of conflict, increased the mutual amount of information.
The performance statistics agency also is provided with failure treatment mechanism and the file cache mechanism uploaded.Upload the failure treatment mechanism and be meant, wait for that then the FTP service of data buffering server 200 is uploaded during the free time again if raw data file is uploaded failure.For this reason, can on each performance statistics agency's file, crossing reserve certain transmission at interval, for example, as mentioned above, the transmitting time of each raw data file needs 10 seconds, 1 base station 120 can be set postpone transmission in 0 second, 2 base stations 140 postpone transmission in 20 seconds, and 160 time-delays of N base station sent in 40 seconds.So, have between each base station 10 seconds transmission at interval, the FTP service idle periods that can be used as data buffering server 200 realizes that failure retransmits.Certainly, failure retransmits also and can take turns after file uploads end one, and new round file is uploaded to concentrate before the beginning and carried out.File cache mechanism is meant that the performance statistics agency understands its raw data file of buffer memory, and assurance can be obtained historical data where necessary again, certainly, carry out for preventing that buffer memory is unconfined, also preset buffer threshold for buffer memory, when file surpasses buffer threshold, then delete the file that exceeds buffer threshold automatically.Buffer threshold, be provided with according to the two dimensional constraint strategy based on time and space, the spatial limitation that buffer threshold for example can be set is 100M, and time restriction is 7 days, then after the raw data file of buffer memory surpasses 100M, with the raw data file deletion of acquisition time above 7 days.
In one embodiment of the invention, can compress raw data file, squeeze operation was for example carried out before sending raw data file to the metadata cache server, thus the data volume can reduce Network Transmission the time; Perhaps, can before the buffer memory raw data file, carry out, thereby can reduce raw data file occupied memory space when buffer memory.
As shown in Figure 2, the main buffer memory of being responsible for raw data files of data buffering server 200, integrate the original performance data and the FTP service provides according to the performance statistics task.Data buffering server 200 is the bridges that connect base station and OMC (operation maintenance center) 220, and wherein data buffering server and base station are linked by Ethernet, are linked by modes such as Ethernet or share service devices with OMC (operation maintenance center).
On the data buffering server 200, management has raw data file pond 202 and integral data file pond 203 usually, and raw data file pond 202 is used for storing a plurality of raw data files that transmit on each base station; Integral data file pond 203 then is used for storing the integral data file that data buffering server 200 is integrated out from a plurality of raw data files.
Be similar to the buffer threshold setting of base station, data buffering server 200 can be provided with the data buffering cycle equally, deletes raw data file and/or the integral data file that exceeds the time limit according to the predefined data buffering cycle.In addition, can also whether change, delete the integral data file according to the acquisition granularity.Such disk space is safeguarded and will be guaranteed that data buffering server 200 has sufficient memory space.In addition, when assignment file 201 reads failure, can continue to integrate raw data file according to the acquisition granularity of last time.
In this way, data buffering server 200 has following function: (1) can alleviate the warehouse-in pressure of OMC (operation maintenance center); (2) can support the performance statistics of many granularities (the acquisition granularity NP can adjust arbitrarily); (3) can realize the secondary supplement collection of obliterated data; (4) the FTP service transmits the guarantee that provides the foundation for file.
OMC (operation maintenance center) 220 is responsible for providing human-computer interaction interface, and human-computer interaction interface can be provided with task for the user, provides performance to check that view is for checking performance statistic.OMC (operation maintenance center) 220 reads the performance statistics mission bit stream that the user is provided with, and writes the assignment file in the data buffering server 200; Read the integral data file from data buffering server 200, the resolution file data, and deposit the data that parse in database; And can provide interface for upper layer NMS.
When reading the failure of integral data file, can wait for then that other integral data files read to finish, read the aforementioned file that reads failure again.
The present invention adopts based on file transfer protocol (FTP), and especially the data transfer mode of File Transfer Protocol has improved the data transmission efficiency in the data management.The big capacity storage space that the data buffering server provides can guarantee that raw data file can the buffer memory regular hour, realizes the secondary supplement collection to obliterated data, has reduced the probability of loss of data.File uplink time to each base station sorts, and has avoided the generation of " message storm ", has alleviated the pressure of offered load.Therefore, the present invention can adapt to the Mass Data Management of many base stations.
Need to prove that the data buffering server among the present invention can be the separate server with mass data caching function of operator or third party's mass data caching server of renting, also can be to integrate plate level server with switch.General, the data buffering server also comprises processor except massage storage, can run application, and is used to provide functions such as FTP service, performance data integration, disk space maintenance.
The present invention is not only applicable to the distributed base station performance statistics, as Wimax base station, the LTETDD base station etc. of declining that distribute, also is applicable to the class distributed base station of band BSC (base station controller), as CDMA 2000 base stations, WCDMA base station and TDS-CDMA base station etc.

Wherein, the third-party server that the data buffering server can use server independently or rent, also can with OMC (operation maintenance center) share service device.In the present embodiment, the data buffering server is an independently server, shares a frame with the network switching equipment.
OMC (operation maintenance center) 220, independently the base station Element management system is communicated by letter with data buffering server 200 by the Ethernet transmission medium, is user and the mutual interface of base station network element.On the one hand, OMC (operation maintenance center) 220 receives the task message that the user is provided with, and writes data buffering server 200; Obtain the performance statistic (integral data file) of data buffering server on the other hand, for the user provides visualization display.
Need to prove that the performance statistics that resides on the base station is acted on behalf of the continuous collecting performance data, and be uploaded to data buffering server 200.When OMC (operation maintenance center) 220 did not have mission bit stream, data buffering server 200 no longer carries out data to be integrated, and OMC (operation maintenance center) 220 also can not read the performance statistic of integration.
For the convenience of describing, present embodiment hypothesis P timer duration is 5 minutes, the NP length of timer is 5 minutes, 10 minutes, 15 minutes etc., and the original performance data acquiescence on the data buffering server kept 7 days, and the performance data of 5000 distributed base stations is added up.

OMC (operation maintenance center) initialization comprises starting server (OMC server), linked database, newly-built acquiescence task dispatching.
S1004, each performance statistics is acted on behalf of the parallel acquisition performance data, carries out mathematical statistics, writes data buffer zone etc.
S1006, behind 5 minutes timer expiries, log-on data transmission lag timer, and restart 5 minutes timers.Deng pending data transmission lag timer expiry, send data to the data buffering server.Data transmission lag timer duration can be calculated according to step S1002 less than 5 minutes, was 60000 milliseconds such as the data transmission lag timer duration of No. 1000 base stations.
S1008, the performance statistic file of the application program retrieve data buffering area on the data buffering server, according to pre-defined algorithm, delete old performance statistic file, the promptly aforesaid raw data file that surpasses the data buffer circle, for example, the data buffering cycle is 7 days, this information of acquisition time in the raw data file of uploading according to the base station then, the deletion life cycle surpasses 7 days file, guarantees that it has sufficient memory space.
S1010, the application program on the data buffering server reads assignment file, obtains performance statistics granularity (the acquisition granularity) NP, according to current system time the NP timer duration is proofreaied and correct, and starts the NP timer.For example, the performance statistics granularity is 15 minutes, and current system time is 2009-04-25 08:12:00:00, and then the duration of the timer NP of Jiao Zhenging is 180000 milliseconds, promptly 3 minutes.This is because generally speaking, and when the performance statistics granularity was set to 15 minutes, the user wished to see data at 15 minutes integral multiple point, 12:00 for example, 12:15,12:30 or the like.Therefore, find that behind startup of server current system time is not 15 minutes an integral multiple point, will do certain correction to the NP timer duration, the NP timer duration when starting is set to the time span from current system time to next 15 hours.Such as, present time is 2009-04-25 08:12:00:00, the NP timer duration during startup just is the time span of 2009-04-25 08:12:00:00 to 2009-04-25 08:15:00:00, also is that duration is 3 minutes.And from next granularity, the NP timer duration reverts to 15 minutes of performance collection granularity, and promptly the NP timer duration of next granularity is the time span from 2009-04-25 08:15:00:00 to 2009-04-2508:30:00:00, and the rest may be inferred.
S1012, NP is overtime when timer, then restarts this timer.
S1014, OMC (operation maintenance center) read the mission bit stream that the user is provided with, and write data buffering server task file.
S1016, the application program retrieval on the data buffering server belongs to original performance data file, packing and the compression of granularity NP, waits for that OMC (operation maintenance center) reads.
