Gather node as the unique external interface of charge gateway system, be connected with the charging center, this gathers node and has the IP address, the charging center obtains this IP address in advance, and this gathers the authority of node to have visit, charging center and gather that transfer files uses the basic network transmission protocols such as FTP, FTAM or SFTP usually between the node.
Owing to gather node provides order usually to the charging center CDR file, for example, gathering node, for the first time to provide the file sequence number to the charging center be 1 to 100 CDR file, and then provide sequence number to the charging center order is 101 to 200 CDR file next time.Owing to can constantly produce new CDR file on each processing node, therefore when having, the space of gathering the CDR file after buffer memory gathers on the node prescribes a time limit, gathering node can be after offering the charging center with CDR file, with the above-mentioned CDR file deletion of buffer memory, be used to gather the new CDR file of storage to discharge memory space.For example, gather node and have the space of 1000 CDR files of maximum storages, when initial 1000 CDR files are numbered from 1 to 1000, when gathering node after the charging center provides 100 CDR files and deleted this CDR file, gathering node will be adjusted into 101 to 1100 to the numbering of 1000 CDR files.Therefore, as long as gather node obtains CDR file from processing node speed, just can satisfy the bill record collection and the work of treatment of chargeing that the charging center continues greater than the speed that CDR file is provided to the charging center.
The second embodiment flow chart of the transmission method of CDR file of the present invention as shown in figure 10, this embodiment shows and gathers node and will directly obtain the process that CDR file is transferred to the charging center from each processing node:
Step 1001: gather the quantity that node is provided by the CDR file that at every turn provides to the charging center set in advance.
Step 1002: each processing node sends the file sequence number of current suitable CDR file.
Step 1003: the sequence number that gathers the CDR file of node comparison document sequence number and definite current needs acquisition.Each processing node record has offered the state information of the CDR file that gathers node, the promptly the last file sequence number that offers the CDR file that gathers node, and each handle will the current CDR file that can upload sequence number send to and gather node, the CDR file that can upload is the CDR file of each processing unit current sequence number value minimum.With processing node K is example, suppose that it is 1,5,7,8 etc. CDR file that this processing node stores the file sequence number, if the current file sequence number is 1 CDR file have been offered and gather node, the CDR file that then current processing node K can upload is the CDR file of file sequence number 5 correspondences.
Step 1004: according to processing node extraction with this sequence number corresponding CDR file of file sequence number from correspondence.
Wherein, the CDR file of extraction is the CDR file of current file sequence number value minimum in the processing node of described correspondence, or the CDR file of the file sequence number correspondence of the file sequence number intermediate value minimum that sends for each processing node.
Concrete, gather after node is provided by the file sequence number of the current CDR file that can provide that each processing node sends, the file sequence number is sorted, by analyzing the storage condition of CDR file sequence number and CDR file, extract and its corresponding CDR file of file sequence number that provides from each processing node.For example, processing node K sends current can the upload file sequence number to be 5 CDR file, then to gather node is gone up extraction document sequence number 5 correspondences from processing node K according to file sequence number 5 CDR file to gathering node.
Certainly, gather node and receive the file sequence number that each processing node sends, after the file sequence number sorted, by analyzing the storage condition of CDR file sequence number and CDR file, also can send extract the request message of the CDR file corresponding with described file sequence number to processing node, processing node receives CDR file to be sent to behind the request message again and gathers node.For example, to send current can the upload file sequence number be 5 CDR file to processing node K to gathering node, gather node and send the request message of the CDR file of extraction document sequence number 5 correspondences to processing node K, processing node K receives behind the request message CDR file with file sequence number 5 correspondences and sends to and gather node.
Need to prove, determine after the file sequence number of the CDR file that current needs obtain in the step 1003, gather node and also can send response, receive the CDR file of corresponding this document sequence that this processing node returns then to the processing node that sends this document sequence number.
Step 1005: the sequencing according to the file sequence number of CDR file gathers the CDR file that obtains.
Step 1006: gather node and send to the charging center by the CDR file that the order of file sequence number will be no more than predetermined number.
In above-mentioned CDR file transmission method embodiment, gather schematic diagram that node obtains corresponding CDR file from each processing node as shown in figure 11:
Suppose to have N processing node, with processing node 1,2, N is example, it is that 1,5,7,8 etc. CDR file is some that processing node 1 stores the file sequence number, it is that 3,4,9,12 etc. CDR file is some that processing node 2 stores the file sequence number, and it is that 2,6,10,11 etc. CDR file is some that processing node N stores the file sequence number.For processing node 1, suppose that the file sequence number is that 1 CDR file was uploaded, it is then current that the most suitable what upload is that the file sequence number is 5 CDR file; For processing node 2, current the most suitable what upload is that the file sequence number is 3 CDR file; For processing node N, current the most suitable what upload is that the file sequence number is 2 CDR file.Above-mentioned three processing nodes send to the current file sequence number that can upload respectively and gather node, gather node according to the file sequence number to corresponding processing node, from the corresponding CDR file of above-mentioned processing node 1,2, N extraction and file sequence number 5,3,2.
The 3rd embodiment flow chart of the transmission method of CDR file of the present invention as shown in figure 12, this embodiment shows and gathers the process that CDR file that node obtains to the processing node of correspondence after with the inquiry file sequence number is transferred to the charging center:
Step 1201: gather the quantity that node is provided by the CDR file that at every turn provides to the charging center set in advance.
Step 1202: gather node to distribution node inquiry and the current corresponding processing node of file sequence number that has distributed.
If exist the distribution node be independent of processing node to distribute unique and continuous file sequence number and ticket serial number for each processing node in the charge gateway system, then distribution node can be preserved the file sequence number that is allocated successfully and the corresponding relation between the processing node after distribution each time.For example, if distribution node has been distributed to processing node K with file sequence number 5, then in distribution node, preserve the corresponding relation between file sequence number 5 and the processing node K.According to above-mentioned stored relation, gathering node can be to distribution node inquiry and the corresponding processing node of file sequence number that has distributed.
Suppose to gather node and to distribution node inquiry file sequence number be the memory location of 5 CDR file, then distribution node knows that according to corresponding relation this CDR file is stored in processing node K, then the information of processing node K is sent to and gathers node.
Step 1203: extract the CDR file corresponding with this document sequence number from the processing node that inquires.
Processing node is according to the memory location of the CDR file that obtains, from the corresponding CDR file of processing node K extraction and file sequence number 5.Certainly, also can be by gathering the memory location of node according to the CDR file that obtains, send the request message that the extraction document sequence number is 5 CDR file to processing node K, processing node K receives behind the request message CDR file with file sequence number 5 correspondences and sends to and gather node.
Step 1204: the sequencing according to the file sequence number of CDR file gathers the CDR file that obtains.
Step 1205: the charging center is extracted the CDR file that is no more than predetermined number by the order of file sequence number from gathering node.
Need to prove that the charging center obtains the mode of CDR file except that initiatively extracting (PULL mode) CDR file to gathering node, can also push (PUSH mode) to the charging center by the CDR file that will gather after node will gather.
In above-mentioned CDR file transmission method embodiment, gather schematic diagram that node obtains corresponding CDR file from each processing node as shown in figure 13:
Suppose to have N processing node, since in the distribution node order assignment some file sequence numbers, this Figure 13 shows file sequence number 55,56,57,58, wherein file sequence number 55 has been distributed to processing node 2, file sequence number 56 has been distributed to processing node 4, file sequence number 57 has been distributed to processing node 1, file sequence number 58 has been distributed to processing node N, after gathering the querying node distribution node, can obtain above-mentioned file sequence number 55,56,57,58 corresponding respectively processing nodes 2,4,1, N gathers node then and extracts corresponding four CDR files to above-mentioned four processing nodes.
