Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
MR file was uploaded according to after the whole moment every 15 minutes in base station simultaneously, but due to network load problem, base station equipment generally all can adopt different time delays to upload MR file, to avoid the impact of uploading network and server simultaneously, and reaches the effect of staggering the time and uploading.
Therefore, the present invention considers that the difference that MR file is uploaded in each base station uploads time delay, improves the method for poll base stations catalogue.
Constant at the strategy of base station equipment upload file, and Internet Transmission condition is not when having a significant change, the time delay that MR file is uploaded in base station is relatively fixed, therefore, MR file analysis software can effectively utilize each base station MR files passe time delay relatively to fix this feature, distributes base station catalogue polling priority, improves base station catalogue polling schemas, thus effectively reduce a large amount of polling operations and do not retrieve the file that need download, cause meaningless loss expense and file synchronization efficiency situation on the low side.
Consult shown in Fig. 1, the idiographic flow that the present invention realizes synchronous ftp server file is:
In the pre-configured stage, all base stations that ftp server is administered are divided into the group of base stations of preset number, and arrange at least one of some update time, wherein, each group of base stations comprises the base station of default some numbers.
Such as, all base stations of ftp server administration are 10000 altogether, according to equipment scale, they are divided into the group of base stations of preset number, i.e. several download thread, such as, are divided into 10 groups, often organize 1000 base stations.Arrange and put update time as morning 8 and late 8 points, it is variant that such setting mainly considers that the network in daytime and evening takies situation possibility, concrete time point can be determined according to specifically the taking situation of network, and some update time of setting can be one or more.
Step 100: add up the time delay mean value that MR file is uploaded in each base station in each group of base stations respectively.
Concrete, before in each group of base stations of statistics, the time delay mean value of MR file is uploaded in each base station, be uploaded to the file generated time of each MR file of described ftp server respectively before arriving at some update time preset according to each base station in a group of base stations, and each MR file described uploads the end time on described ftp server, what obtain that each base station uploads MR file uploads time delay set.Upload time delay set according to each acquisition, corresponding base station uploads the time delay mean value of MR file respectively.
The file generated time of MR file here determines according to the filename of MR file.The filename naming rule of existing MR file is " TD-LTE_MRO_< producer title >_< device coding >_< file generated time >.xml ".Therefore, according to the file generated time in the filename of a MR file, and this file is uploaded to ftp server uploads the end time, and what can obtain this file uploads time delay.
Such as, base station A to it under the base station catalogue corresponding to ftp server, upload the MR file of TD-LTE_MRO_< producer title 1>_< device coding 1>_<11:45:00>.x ml, the upload end time of this file on ftp server is 11:45:56, can the time delay of uploading of this file be therefore 56 seconds.
What be uploaded to each MR file of ftp server according to a base station uploads time delay set, and the number of MR file, obtains the time delay mean value that MR file is uploaded in this base station.
Such as, that uploads MR file according to said method accounting base-station A uploads time delay at every turn, the set of uploading time delay of uploading MR file for 56s, 56s, 56s}, and as seen this base station to upload time delay substantially fixing, and calculation delay mean value.
Step 110: when putting the update time that arrival is preset, uploading the time delay mean value of MR file respectively according to each base station in each group of base stations, determining the up-to-date base station downloading order of corresponding base station group.
When putting the update time that arrival is preset, the time delay mean value of MR file is uploaded according to each base station in a group of base stations, all base stations in a group of base stations are uploaded the time delay mean value of MR file by order arrangement from small to large, and using the up-to-date base station downloading order of ranking results as a group of base stations, the less sequence of average of instant Yangjing is more forward, more preferential when poll.
Such as, with by base station A, the group of base stations 1 of base station B, base station C, base station D composition is example, and their time delay mean value is respectively: 56s, 33s, 100s, 61s.This time delay mean value sorts to base station from small to large, can obtain up-to-date base station downloading order to be: base station B, base station D, base station A, base station C.
Step 120: respectively according to the up-to-date base station downloading order of each group of base stations, poll is carried out to the file directory of each base station corresponding in ftp server, when determining to preserve up-to-date MR file in the file directory that one of them base station is corresponding, download the up-to-date MR file that a base station is corresponding.
Here it may be noted that the up-to-date base station downloading order for each group of base stations, carry out the poll of base station catalogue respectively simultaneously, namely multiple MR file download thread is searched simultaneously and is downloaded up-to-date MR file, improves the efficiency of poll.
Such as, corresponding to the up-to-date base station downloading order of group of base stations 1, base station B, base station D, base station A, base station C, carry out poll to the file directory of the base station B of the correspondence in ftp server, base station D, base station A, base station C, judged whether up-to-date MR file.
When determining that the file generated time of the MR file preserved in the file directory that one of them base station is corresponding is greater than the file generated time of the last MR file for a base station download, determine to preserve up-to-date MR file in the file directory that base station is corresponding, and download up-to-date MR file corresponding to a base station.
The file generated time of MR file here is also obtained by the filename of MR file.
Such as, the file of the MR file that base station A uploads recently is called TD-LTE_MRO_< producer title 1>_< device coding 1>_<11:45:25>.x ml, when being polled to base station A, the MR file that a file is called TD-LTE_MRO_< producer title 1>_< device coding 1>_<12:00:43>.x ml is saved under finding file directory corresponding to base station A, therefore determine that this file is up-to-date MR file and downloads this file.
Consulting shown in Fig. 2 and Fig. 3, is the particular flow sheet of ftp file synchronous in the present invention.

Step 201: judge whether to arrive some update time preset, if perform step 202, otherwise performs step 203.
This sentences and puts update time as early 8 and late 8 is example.When determine arrive update time put time, need to upgrade the up-to-date base station downloading order of each group of base stations.
Step 202: the time delay mean value uploading MR file according to each base station in each group of base stations, upgrades the base station downloading order of corresponding base station group.
When determine arrive update time put time, add up the time delay mean value that MR file is uploaded in each base station in each group of base stations.
According to adding up the time delay mean value that MR file is uploaded in each base station obtained in two group of base stations 1 and 2, the base station downloading order in two group of base stations being upgraded, obtains:
The up-to-date base station downloading order of group of base stations A, base station 3, base station 2, base station 1, base station 4.
The up-to-date base station downloading order of group of base stations B, base station 2, base station 4, base station 1, base station 3.
Step 203: wait for some update time arriving and preset.
When do not arrive put update time time, continue wait for arrive update time point.
Step 204: after having upgraded the base station downloading order of each group of base stations, wait for next treatment cycle.
