The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
Base station uploaded MR files simultaneously according to every 15 minutes after the whole moment, but due to network load problem, base station equipment Typically all MR files can be uploaded using different time delays, to avoid uploading the impact to network and server simultaneously, and reached Stagger the time the effect of upload.
Therefore, the present invention considers that each base station uploads the different of MR files and uploads time delay, improves poll base stations catalogue Method.
Transmitting file is tactful constant in base station equipment, and when network transmission condition does not have significant change, base station uploads The time delay of MR files is that comparison is fixed, therefore, when MR file analyses software can be uploaded effectively using each base station MR files Prolong this feature that is relatively fixed, distribute base station catalogue polling priority, improve base station catalogue polling schemas, it is big so as to effectively reduce The polling operation of amount does not retrieve the file that need to be downloaded, and causes the relatively low situation of meaningless loss expense and file synchronization efficiency.
As shown in fig.1, the present invention realizes that the idiographic flow of 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 set extremely A few renewal time point, wherein, each group of base stations includes the base station of default some numbers.
For example, all base stations of ftp server administration are altogether 10000, according to equipment scale, it is divided into presetting The group of base stations of number, i.e. several download threads, for example, it is divided into 10 groups, every group of 1000 base stations.Renewal time point is set for early 8 points and 8 points of evening, so setting mainly may variant, the specific time in view of the network occupancy situation in daytime and evening Point can be depending on the specific occupancy situation of network, and the renewal time point of setting can be one or more.
Step 100：The time delay average value that each base station in each group of base stations uploads MR files is counted respectively.
Specifically, before the time delay average value that each base station in counting each group of base stations uploads MR files, respectively The each of the ftp server is uploaded to before the arrival of default renewal time point according to each base station in a group of base stations The file generated time of MR files, and upload end time of each MR files on the ftp server, obtain every One base station uploads the upload time delay set of MR files.According to each upload time delay set of acquisition, distinguish on corresponding base station Pass the time delay average value of MR files.
Here the file generated time of MR files is determined according to the filename of MR files.The text of existing MR files Part name naming rule is " TD-LTE_MRO_<Vendor name>_<Device coding>_<The file generated time>.xml”.Therefore, according to File generated time in the filename of one MR file, and this document are uploaded to the upload end time on ftp server, can To obtain the upload time delay of this document.
For example, base station A to it under the base station catalogue corresponding to ftp server, upload TD-LTE_MRO_<Vendor name 1 >_<Device coding 1>_<11:45:00>.xml MR files, upload end time of this document on ftp server are 11: 45:56, therefore the upload time delay that can obtain this document is 56 seconds.
The upload time delay set of each MR files of ftp server, and of MR files are uploaded to according to a base station Number, obtain the time delay average value that the base station uploads MR files.
For example, the upload time delay of MR files is uploaded every time according to above method accounting base-station A, when uploading the upload of MR files The collection prolonged is combined into { 56s, 56s, 56s }, it is seen that the upload time delay of the base station is substantially stationary, and calculation delay average value.
Step 110：When reaching default renewal time point, uploaded respectively according to each base station in each group of base stations The time delay average value of MR files, determine the newest base station downloading order of corresponding base station group.
When reaching default renewal time point, when Yangjing of MR files is uploaded according to each base station in a group of base stations Average, the time delay average value that all base stations in a group of base stations are uploaded to MR files are arranged by order from small to large, and will row Newest base station downloading order of the sequence result as a group of base stations, the instant smaller sequence of Yangjing average is more forward, is got in poll Preferentially.
For example, with by base station A, base station B, base station C, exemplified by the group of base stations 1 of base station D compositions, their time delay average value point It is not：56s, 33s, 100s, 61s.The time delay average value is ranked up to base station from small to large, and it is suitable can to obtain newest base station download Sequence is：Base station B, base station D, base station A, base station C.
Step 120：It is each to being corresponded in ftp server respectively according to the newest base station downloading order of each group of base stations The file directory of individual base station is polled, when it is determined that preserving newest MR files in file directory corresponding to one of base station When, download newest MR files corresponding to a base station.
It needs to be noted that for the newest base station downloading order of each group of base stations, base station catalogue is carried out simultaneously respectively Poll, i.e., multiple MR file downloads threads are searched and download newest MR files simultaneously, improve the efficiency of poll.
For example, corresponding to the newest base station downloading order of group of base stations 1, base station B, base station D, base station A, base station C, FTP is taken The corresponding base station B, base station D, base station A being engaged in device, base station C file directory are polled, and determine whether newest MR files.
When it is determined that the file generated time of the MR files preserved in file directory corresponding to one of base station be more than it is nearest The file generated time for the MR files once downloaded for a base station, determine to preserve in file directory corresponding to a base station Newest MR files, and download newest MR files corresponding to a base station.
Here the file generated time of MR files is also to be obtained by the filename of MR files.
For example, the entitled TD-LTE_MRO_ of file for the MR files that base station A is uploaded recently<Vendor name 1>_<Device coding 1 >_<11:45:25>.xml, when being polled to base station A, find and a filename is saved under file directory corresponding to the A of base station For TD-LTE_MRO_<Vendor name 1>_<Device coding 1>_<12:00:43>.xml MR files, it is thus determined that this document is Newest MR files simultaneously download this document.
Refering to shown in Fig. 2 and Fig. 3, for the particular flow sheet of synchronous ftp file in the present invention.
Fig. 2 show the idiographic flow of renewal base station downloading order.
Step 201：Judge whether to reach default renewal time point, if performing step 202, otherwise perform step 203.
Exemplified by this sentences renewal time point as and 8 points of evening at early 8 points., it is necessary to each when it is determined that reaching renewal time point The newest base station downloading order of group of base stations is updated.
Step 202：The time delay average value of MR files is uploaded according to each base station in each group of base stations, updates corresponding base The base station downloading order for group of standing.
When it is determined that reaching renewal time point, when Yangjing that each base station in each group of base stations uploads MR files is counted Average.
The time delay average value of MR files is uploaded according to each base station for counting to obtain in two group of base stations 1 and 2, to two Base station downloading order in group of base stations is updated, and is obtained：
Group of base stations A newest base station downloading order, base station 3, base station 2, base station 1, base station 4.
Group of base stations B newest base station downloading order, base station 2, base station 4, base station 1, base station 3.
Step 203：Wait and reach default renewal time point.
When not reaching renewal time point, continue waiting for reaching renewal time point.
Step 204：After the base station downloading order of each group of base stations has been updated, next process cycle is waited.
Therefore, return to step 201, judge whether to reach next renewal time point.
As shown in fig.3, after renewal time point, to download the idiographic flow of newest MR files.
Step 301：Obtain the responsible base station downloading order of current thread, component initial download list.
So that currently responsible download thread is group of base stations A as an example, group of base stations A newest base station downloading order, base station 3, base Stand 2, base station 1, base station 4.
Step 302：According to file directory corresponding to each base station of download list successively poll, newest MR files are obtained.
Group of base stations A newest base station downloading order, is polled to base station 3, base station 2, base station 1, base station 4 successively
Step 303：Judge whether the file generated time with MR files is more than under base station catalogue corresponding to a base station The file of the file generated time for the MR files downloaded recently, if so, step 304 is performed, otherwise return to step 302, according to Base station downloading order inquires about file directory corresponding to next base station.
Here the method for using the file generated time included in comparison document name, it is determined whether newest to need to download MR files.When being polled to base station 2, the entitled TD-LTE_MRO_ of file for the MR files that base station 2 uploads recently<Vendor name 1>_ <Device coding 1>_<8:15:25>.xml, when being polled to base station A, find and preserve one under file directory corresponding to the A of base station The individual entitled TD-LTE_MRO_ of file<Vendor name 1>_<Device coding 1>_<8:30:43>.xml MR files, therefore judge base Standing 2 has new MR files, then downloads the MR files.
Step 304：Newest MR files are downloaded, and the MR files of this download are downloaded as respective base station is the last File.
Step 305：Calculate the upload time delay of this document.
At the end of file generated time in the filename of this document and the upload being finally uploaded on ftp server Between, calculate the upload time delay of this document.For file TD-LTE_MRO_<Vendor name 1>_<Device coding 1>_<8:30:43> .xml, it is uploaded to the upload end time point 8 of ftp server:31：14, therefore the upload time delay of this document is 31s.
