The flow chart of the first embodiment of the generation method of the bill file of the present invention is as shown in Figure 5:

Step 501: The processing node performs processing after receiving the billing information, and sends a request message when the conditions for generating the bill file are met.

Wherein, meeting the conditions for generating the bill file specifically includes: the received billing information is processed and a corresponding processing record is generated; or the time since the last generation of the bill file exceeds the preset time; or the generated processing record reaches preset quantity.

Wherein, the request message carries information indicating the number of bills that need to be included in the bill file to be generated, and the information is used to request the allocation of unique and continuous file serial numbers within the scope of all processing nodes and the number of bills in the bill file to be generated. Unique and continuous call ticket serial number.

Step 502: Receive the returned file serial number and bill serial number corresponding to the request message.

Here, the distribution node that implements the distribution function may be another processing node in the charging gateway system, or may be a collection node in the charging gateway system.

Step 503: Generate a bill file according to the serial number of the file and the serial number of the bill.

The flow chart of the second embodiment of the generation method of the bill file of the present invention is shown in Figure 6. This embodiment takes a certain processing node in the billing gateway system as an example, and describes in detail the process of generating the bill file in the processing node. process, assuming that the processing node is processing node K:

Step 601: After receiving the billing information, the processing node K prepares to generate a bill and a bill file including the bill.

Each bill file contains multiple bills, and each bill stores received billing information. It is assumed that processing node K is currently preparing to generate 100 bills in the bill file.

Step 602: The processing node K sends a message for requesting the serial number of the bill and the serial number of the file to the distribution node.

The function of distributing bill serial numbers and file serial numbers in the billing gateway system can be realized by the distribution node, which can be a certain processing node in the billing gateway system of the embodiment of the present invention, or can be independent of all processing nodes. Nodes of nodes, for example: summary nodes, third-party nodes independent of processing nodes, summary nodes;

In this embodiment, taking a node independent of all processing nodes as an example of a distribution node, processing node K sends a message requesting a bill serial number and a file serial number to the distribution node, and the message carries the words contained in the bill file. Order quantity 100 pcs.

Step 603: Allocate a file serial number to the bill file according to the generation sequence of the bill file.

After the allocation node receives the request message, it allocates a file serial number that is continuous and unique to the processing node K according to the currently allocated file serial number. Assume that the file serial number assigned by the distribution node last time is "10", if the step size of the file serial number is 1, then the file serial number of the distribution order of the bill file distribution sequence of the distribution node is "11" for the processing node K, of course the file sequence The step value of the number can be set to other values.

The allocation node further allocates continuous and unique bill serial numbers to the processing node K according to the currently allocated bill serial numbers. Assuming that the bill serial number assigned by the allocation node last time is "100", the allocation node sequentially allocates the bill serial numbers from "101" to "200" for the 100 bills in the bill file.

Step 605: The distribution node sends the bill serial number and file serial number to the processing node K.

Step 606: The processing node K generates the bill and the bill file according to the bill serial number and the file serial number.

After processing node K receives the assigned file serial number "11" and bill serial numbers "101" to "200", it generates a bill file according to the file serial number and bill serial number, and saves the generated bill file.

Step 607: The processing node K sends a message that the file serial number and bill serial number are successfully received.

In the embodiment of the generation method of the bill file of the present invention, the processing node obtains the bill serial number and the file serial number through the mode of request response, because the bill serial number and the file serial number are uniformly assigned by the distribution node, so it can be Ensure that the file serial numbers and bill serial numbers generated by all processing nodes in the billing gateway system remain unique and continuous.

The present invention also provides an embodiment of the transmission system of a bill file, which is used to transmit the generated bill file, and the block diagram of this embodiment is as shown in Figure 7:

The bill file generation system includes at least one processing node 710 and a collection node 720, and the at least one processing node 710 is connected to the distribution node 720 respectively. The processing node 710 is used for storing and generating the bill file, and the bill file is a bill file with a unique and continuous file sequence number within the scope of all processing nodes, and the bill in the bill file has a unique and continuous bill flow No.; after collecting node 720 is used for obtaining file sequence number, obtains corresponding bill file from corresponding processing node according to described file sequence number, according to the size of described obtaining file sequence number, sequentially summarizes described obtaining bill file, and Outputting the summarized bill file.

Further, the collection node may also include a storage unit, configured to store the preset number of bill files provided to the billing center each time.

The present invention also provides an embodiment of a transmission device for bill files, which is used to transmit the generated bill files. The block diagram of this embodiment is shown in Figure 8:

The device for transmitting the bill file includes: an obtaining unit 810 , a summarizing unit 820 and an output unit 830 . Wherein, the obtaining unit 810 is used to obtain the file serial number, and obtain the corresponding bill file from the corresponding processing node according to the file serial number, and the collection node is a node located in the same billing gateway system as the processing node; The unit 820 is configured to sequentially summarize the obtained bill files according to the size of the obtained file sequence numbers; the output unit 830 is configured to output the summarized bill files.

Specifically, the obtaining unit 810 may further include: a receiving unit, configured to receive the file serial number sent by each processing node, where the file serial number is the file serial number with the smallest value of the current file serial number of each processing node; a comparison unit, It is used to compare the file serial number to determine the serial number of the bill file that needs to be obtained currently; the extraction unit is used to extract the bill file corresponding to the file serial number from the corresponding processing node according to the file serial number.

The present invention also provides an embodiment of a method for transmitting a bill file, and the method embodiment is applied to a charging system including a charging gateway system and a charging center, and the charging gateway system includes several processing nodes and is connected to the charging system. The only aggregation node connected to the fee center.

The flow chart of the first embodiment of the transmission method of the bill file of the present invention is as shown in Figure 9:

Step 901: The summary node obtains the file serial number, and obtains the corresponding bill file from the corresponding processing node according to the file serial number.

Wherein, the summarizing node can directly obtain the bill file from each processing node, or can obtain the bill file from the corresponding processing node after querying the serial number of the file.

The summarization node has a monitoring function, and when it is monitored that the number of bill files in the summarization node decreases, the bill files can be obtained from each processing node in the billing gateway system.

Step 902: Summarize the obtained bill files sequentially according to the size of the obtained file sequence numbers.

Step 903: Output the summarized bill file to the billing center.

Wherein, after the summarizing node sums up the bill file, the billing center may actively extract the bill file from the summarizing node, or the summarizing node may actively push the bill file to the billing center. The billing center performs further billing processing on the bill file provided by the summary node in the billing gateway system,

As the only external interface of the billing gateway system, the summary node is connected to the billing center. The summary node has an IP address. The billing center obtains the IP address in advance and has the authority to access the summary node. Transferring files between files usually uses basic network transfer protocols such as FTP, FTAM or SFTP.

Because the summarization node usually provides sequential bill files to the billing center, for example, the summarization node provides bill files with file serial numbers from 1 to 100 to the billing center for the first time, then the next time the billing node provides serial numbers to the billing center in order 101 to 200 bill files. Since new bill files will be continuously generated on each processing node, when the space for caching and summarizing bill files on the summarizing node is limited, the summarizing node can provide the bill files to the billing center after the summarizing node has cached the above-mentioned Delete single file to free up storage space for collectively storing new bill files. For example, the summarization node has a space to store up to 1000 bill files, and the 1000 bill files are numbered from 1 to 1000 initially, when the summarization node provides 100 bill files to the billing center and deletes the bill files Finally, the aggregation node adjusts the numbering of the 1000 bill files to 101 to 1100. Therefore, as long as the summarization node obtains the bill file from the processing node faster than the speed of providing the bill file to the billing center, the billing center can be satisfied with continuous bill collection and billing processing.

The flow chart of the second embodiment of the transmission method of the bill file of the present invention is shown in Figure 10, this embodiment shows the process that the summary node will directly obtain the bill file from each processing node and transmit it to the billing center:

Step 1001: The summarizing node saves the preset number of bill files provided to the billing center each time.

Step 1002: Each processing node sends the file serial number of the currently applicable bill file.

Step 1003: the summarizing node compares the serial numbers of the files and determines the serial number of the bill file that needs to be obtained currently. Each processing node records the status information of the bill file that has been provided to the summarizing node, that is, the file serial number of the bill file provided to the summarizing node last time, and each processing sends the serial number of the bill file that can be uploaded currently to the summarizing node, which can The uploaded bill file is the bill file with the smallest current serial number value of each processing unit. Taking the processing node K as an example, assuming that the processing node stores bill files with file serial numbers of 1, 5, 7, 8, etc., if the current file serial number is 1, the bill file has been provided to the summary node, then the current processing node K The bill file that can be uploaded is the bill file corresponding to file serial number 5.

Step 1004: extract the bill file corresponding to the serial number from the corresponding processing node according to the serial number of the file.

Wherein, the extracted bill file is the bill file with the smallest value of the current file serial number in the corresponding processing node, or the bill file corresponding to the smallest file serial number among the file serial numbers sent by each processing node.

Specifically, after receiving the file serial numbers of bill files currently available from each processing node, the summarizing node sorts the file serial numbers, and analyzes the serial numbers of bill files and the storage conditions of bill files, and collects data from each processing node. Extract the bill file corresponding to the provided file serial number. For example, the processing node K sends the bill file with file serial number 5 that can be uploaded to the summarizing node at present, and the summarizing node extracts the bill file corresponding to the file serial number 5 from the processing node K according to the file serial number 5.

Of course, after the summary node receives the file serial numbers sent by each processing node, after sorting the file serial numbers, it can also send the extraction and the file sequence to the processing node by analyzing the serial number of the bill file and the storage situation of the bill file. number corresponding to the bill file request message, the processing node sends the bill file to the summary node after receiving the request message. For example, the processing node K sends the bill file that can currently upload the file serial number 5 to the summarizing node, and the summarizing node sends a request message to extract the bill file corresponding to the file serial number 5 to the processing node K. After receiving the request message, the processing node K will The bill file corresponding to the file sequence number 5 is sent to the aggregation node.

It should be noted that, after determining the file serial number of the bill file that needs to be obtained in step 1003, the summary node can also send a response to the processing node that sent the file serial number, and then receive the bill corresponding to the file sequence returned by the processing node. document.

Step 1005: Summarize and acquire the bill files according to the order of the file serial numbers of the bill files.

Step 1006: The summarizing node sends the bill files not exceeding a preset number to the billing center according to the order of file serial numbers.

In the above embodiment of the bill file transmission method, a schematic diagram of the collection node obtaining the corresponding bill file from each processing node is shown in Figure 11:

Assuming that there are N processing nodes, taking processing nodes 1, 2, and N as examples, processing node 1 stores several bill files with file serial numbers 1, 5, 7, 8, etc., and processing node 2 stores file serial numbers 3 , 4, 9, 12, etc., and the processing node N stores a number of bill files with file serial numbers 2, 6, 10, 11, etc. For processing node 1, assuming that the bill file with file serial number 1 has already been uploaded, the most suitable upload is the bill file with file serial number 5; for processing node 2, the most suitable uploaded file is the bill file with file serial number 3 The bill file; for the processing node N, the bill file with the file serial number 2 is the most suitable to upload at present. The above three processing nodes respectively send the serial numbers of files that can be uploaded to the summary node respectively, and the summary node sends the corresponding processing nodes according to the file serial numbers, and extracts the file serial numbers 5, 3, 2 corresponds to the bill file.

The flow chart of the third embodiment of the transmission method of the bill file of the present invention is shown in Figure 12. This embodiment shows the process that the summarizing node obtains the bill file from the query file serial number to the corresponding processing node and transmits it to the billing center :

Step 1201: The summarizing node saves the preset number of bill files provided to the billing center each time.

Step 1202: The aggregation node inquires the allocation node for the processing node corresponding to the currently allocated file serial number.

If there is an allocation node independent of the processing nodes in the billing gateway system that assigns unique and continuous file serial numbers and bill serial numbers to each processing node, the allocation node can save the successfully allocated file serial numbers and processing numbers after each allocation. Correspondence between nodes. For example, if the distribution node distributes the file serial number 5 to the processing node K, the corresponding relationship between the file serial number 5 and the processing node K is saved in the distribution node. According to the above-mentioned stored correspondence, the summarizing node can inquire about the processing node corresponding to the allocated file serial number from the allocating node.

Assuming that the summarization node inquires the storage location of the bill file whose file serial number is 5 from the distribution node, the distribution node knows that the bill file is stored in the processing node K according to the corresponding relationship, and then sends the information of the processing node K to the summarization node.

Step 1203: Extract the bill file corresponding to the file serial number from the queried processing node.

The processing node extracts the bill file corresponding to the file serial number 5 from the processing node K according to the storage location of the obtained bill file. Of course, it is also possible for the summarizing node to send a request message for extracting the bill file whose file serial number is 5 to the processing node K according to the storage location of the obtained bill file. Files are sent to summarization nodes.

Step 1204: Summarize and acquire the bill files according to the order of the file serial numbers of the bill files.

Step 1205: The billing center extracts the bill files not exceeding a preset number from the summarizing node according to the sequence of file serial numbers.

It should be noted that the billing center obtains the bill file in addition to actively extracting the bill file from the summarizing node (PULL mode), or the summarizing node pushes the summarized bill file to the billing center (PUSH mode).

In the above embodiment of the bill file transmission method, a schematic diagram of the collection node obtaining the corresponding bill file from each processing node is shown in Figure 13:

Assuming that there are N processing nodes, since a number of file serial numbers are sequentially allocated in the allocation node, this figure 13 shows file serial numbers 55, 56, 57, and 58, wherein file serial number 55 has been assigned to processing node 2, and file serial numbers Serial number 56 has been assigned to processing node 4, file serial number 57 has been assigned to processing node 1, and file serial number 58 has been assigned to processing node N. After the summary node queries the assigned node, the above file serial number 55, 56 , 57 , and 58 respectively correspond to processing nodes 2 , 4 , 1 , and N, and then the summary node extracts four bill files corresponding to the above four processing nodes.

Through the description of the embodiment of the present invention, it can be known that the application of the embodiment of the present invention can ensure that all processing nodes generate unique and continuous bill serial numbers and bill serial numbers, avoiding the billing center from identifying duplicate bills and bill files, by This reduces the complexity of bill verification in the billing center; secondly, since the bill files of each processing node are obtained through a summary node, a unified billing interface can be provided to the billing center, saving each processing node from directly contacting billing The IP resources to be consumed when the center is connected to avoid exposing the network structure of the billing gateway system to the outside. The interconnection is simpler; thirdly, since only the aggregation node is connected to the external billing center, it avoids disclosing the network structure and address information of the processing nodes to the outside world, and improves the security of the entire billing gateway system.
