It consists of the disk control part 50b which accesses. In addition, the billing processing device 60 requests the transfer of the billing data to the maintenance processor 50a and at the same time receives the billing data transmitted from the maintenance processor 50a and stores it in the hard disk 60b or prints the printer ( Issue a billing statement through 60c).

In the above-described conventional billing data transmission method, since data transmission is performed online, it is a factor that can increase the load of the electronic exchange 50, and the transmission time in transmitting a large amount of billing data by RS232C serial method is increased. It is a lot of problems, and it is difficult to transfer blocks when an error occurs in a specific block.

As another problem, since the billing data file and the subscriber information file each consist of one file, it takes a lot of data access time. Therefore, when the number of subscribers is large, the amount of processing data also increases proportionally, resulting in a longer access time. This occurred.

Accordingly, an object of the present invention is to charge data generated in the exchange is connected to a separate MTU (magnetic tape unit) in an offline state to transmit data in a parallel transmission method to transmit data at high speed without affecting the exchange at all. To be able to.

Another object of the present invention is to minimize data loss by selectively transmitting data from the next block when a specific data error occurs, and to process billing data and subscriber data for each subscriber group in file processing. In other words, the processing speed is improved by not accessing unnecessary data.

As described above, the system of the charging processing apparatus of the electronic exchange includes a magnetic tape storing the charging data generated at the exchange, a small computer connected directly to the magnetic tape to access data stored in the magnetic tape, and the accessed And a printer for outputting data.

Hereinafter, a block diagram of FIGS. 2 through 3 attached to the present invention will be described in detail with reference to the flowcharts of FIGS. 4 through 8.

First, the processing of the billing data performed by the billing data processing unit 20b of the small computer 20 will be described. When the magnetic tape reading command of the operator is input in step 100, the central processing unit of the small computer 20 reads the read data in step 110. Analyze In this case, the analyzed content is stored in the hard disk in step 130 when the frequency of the mountain climbing charge, and the storage file name is BKyymmnn.BLK, but the analyzed content is read the data in step 120 of detailed billing date and time. The storage file name is DTyymmnn.DET. Then, the central processing unit of the small computer 20 in step 140 detects the end of the read data. Then, in step 150, when the operator's storage file analysis and separation command is input, in step 160, the central processing unit of the small computer 20 analyzes whether the type of the stored data is detailed charging or mountain climbing charging. In this case, in step 170, the stored data is converted into a text file and stored in a hard disk, and the stored file name is BKyymmnn.TAX. However, in step 160, the central processing unit of the small computer 20 determines whether the stored data is the calling party first group in step 190. In this case, when the stored data is determined to be the first group of subscribers, in step 220, the stored data is converted into a text file and stored in the hard disk, and the storage file name is DTyymm01.TAX. However, when the stored data is not the calling party first group in step 190, the central processing unit of the small computer 20 determines whether the stored data is the calling party second group in step 200. In this case, when the stored data is determined to be the second group of subscribers, in step 230, the stored data is converted into a text file and stored in the hard disk, and the storage file name is DTyymm02.TAX. However, when the stored data is not the calling party second group in step 200, the central processing unit of the small computer 20 determines whether the stored data is the calling party n group in step 230. In this case, when it is determined that the stored data is the n-th group of subscribers, in step 240, the stored data is converted into a text file and stored in the hard disk, and the storage file name is DTyymm0n.TAX. Then, in step 180 the central processing unit of the small computer 20 detects whether the conversion of the stored data is finished. Then, when the conversion of the stored data is finished, the program ends. As described above, registration, modification, and inquiry output of subscriber information performed by the charging information processing unit 20c of the small computer 20 after the conversion and storage of the charging data are described. And when the correction and inquiry output command is input, in step 200, the central processing unit of the small computer 20 detects whether the input command is registered or corrected. In this case, when the input command is registered and modified, the central processing unit of the small computer 20 detects whether the registered or modified subscriber group is the first group and detects the first group in step 240. And modify the subscriber's information file to be modified. Thereafter, in step 260, the modified subscriber's information file is stored in the hard disk 30. However, in step 240, if the subscriber group to be registered and modified is not the first group, when the corresponding group of subscribers to be registered and modified is detected from step 250 to the nth group, the corresponding group of subscribers to be registered and modified is detected. In the step, modify the information file of the subscriber to be registered and modified. Thereafter, in step 280, the modified subscriber's information file is stored in the hard disk 30. However, when the input command is not registered and corrected in step 200, the central processing unit of the small computer 20 detects whether a command of inquiry output is input in step 210. FIG. In this case, when the command of the inquiry output is input, in step 220, the central processing unit of the small computer 20 detects whether the subscriber group to be outputted is the first group and detects the first group in step 290. Inquire the subscriber's information file to output. Thereafter, in step 310, the inquired information file of the subscriber is output to the screen or the printer 30. However, in step 220, if the subscriber group for inquiry output is not the first group, in step 230, when the corresponding group of subscribers for inquiry output is detected until the nth group, the corresponding group of subscribers for inquiry output is detected. In step the query the information file of the subscriber to be output. Then, in step 310, the information file of the inquired subscriber is output to the screen or the printer 30, and the program is terminated. At this time, in order to explain in more detail the format of the billing data as shown in Figs. 6 and 7, for example, first enter the dial number of the subscriber to be accessed. In this case, a total of four digits (yyyy) is detected by adding the three digits of the station number and the first digit, and then one of the small subscriber groups n corresponding to the four digits is selected and accessed. The subscriber information is also accessed in the same manner as the method of accessing the billing data.

As described above, after the registration, modification and inquiry output of the subscriber information performed by the billing information processing unit 20c, the billing statement issuance according to the billing statistics performed through the billing statement issuing unit 20d is described. Orders the issuance of billing statements. Then, in step 350, the central processing unit of the small computer 20 detects whether the group of the subscriber who issued the billing statement is issued is the first group. In this case, when the group of the subscriber who has issued the billing statement is the first group, in step 390, the information of the subscriber who has been ordered to issue the billing statement is read from the subscriber information file, and in step 400, the billing data file according to the subscriber information is read. Serve Then, in step 450, the charge of the read billing data is calculated and stored in the hard disk 30, or the bill is output to the printer 40. However, if the group of subscribers who have issued the billing statement issuing command in step 350 is not the first group, the central processing unit of the small computer 20 detects whether the group of subscribers who have issued the billing bill issuing command is the second group in step 360. . In this case, when the group of the subscriber who has issued the billing statement is the second group, in step 410, the information of the subscriber who has been ordered to issue the billing statement is read from the subscriber information file, and in step 420, the billing data file according to the subscriber information is read. Serve Then, in step 450, the charge of the read billing data is calculated and stored in the hard disk 30, or the bill is output to the printer 40. However, if the group of subscribers who have issued the billing statement issuance command in step 350 is not the second group, the group of subscribers who have been issued the billing statement issuance command corresponding to the nth group is detected in step 360. Then, when the group of the subscriber who has issued the billing statement is the second group, in step 410, the information of the subscriber who has been ordered to issue the billing statement is read from the subscriber information file. Read it. Then, in step 450, the charge of the read billing data is calculated and stored in the hard disk 30, or the bill is output to the printer 40. Then, in step 490, it detects whether there is an order for issuing the bill of the next subscriber, and if the issue is made, it feeds back to step 350 and performs the above process again, but there is no order for issuing the bill of bill of the next subscriber. End the program.

As described above, the present invention provides a method of transmitting data in a parallel transmission method by connecting a separate magnetic tape (MT) in an offline state, thereby transmitting a large amount of charging data in a RS232C serial method. As a result, it is possible to reduce the transmission time, to block transmission when an error occurs in a specific block, and to shorten the time for accessing the billing data file and the subscriber information file.
