Description

Charging data transmission method in charging relay system of centralized charging system

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a centralized charging system (hereinafter referred to as "CAMA") type billing processing system, and more particularly to a mediation device (hereinafter referred to as "MD") connected between an exchange and a billing apparatus. To a billing data transmission method.

In the process of processing the charge in the conventional exchange, when collecting the charge in the exchange country called the home exchange, which is operated unattended, the operator moves to the place where the home exchange is located and collects the charge information in the magnetic tape. We used LAMA (Local Automatic Message Account) method to carry out billing by transporting to computer center by car and end-of-month processing for user's fee. However, the conventional billing processing method of the LAMA method has a problem that unnecessary waste of manpower occurs and frequent loss of billing information data during transportation. In order to solve this problem, in recent years, the CAMA method of transmitting the billing data generated by the exchange online to the billing processing device has become a common trend.

1 is a flowchart illustrating a process of processing charging data in the MD of the conventional CAMA charging system. Referring to the charging data online transmission operation in the CAMA method with reference to FIG. 1, first, the MD generates a main process for collecting the charging data in step (100), and proceeds to step (102) to collect the charging data. Set up a main session with the exchange. In step 104, the MD receives and collects billing data from the exchange through the established main session. In step 106, the MD checks whether a billing file is received. In this case, if the receiving of the charging file is completed in step 106, the MD proceeds to step 108 to generate a child process for transmitting the charging data and charges the charging file in step 110. To the device. The billing file list request or billing data retransmission request may be generated from the billing processing device while the billing data is transferred from the exchange to the billing processing device in the above process. In this case, the billing file list request is generated from the billing processing device. In case 112, in response to this, the process proceeds to step 114 to generate a sub-process for collecting the billing file list. In step 116, the MD collects the billing file list through the main session, and in step 118, the collected billing file list is transmitted to the billing apparatus. Subsequently, in step 120, the sub-process which has been generated for collecting the billing file list is destroyed, and then the process returns to step 104 and performs steps 104 to 110 again.

In addition, if the request for retransmission of the billing data from the billing processing device occurs while the MD is transferring the billing data to the billing processing device, the MD proceeds to step 124 in response to the billing data through the main session. Recollect Then, when the reception of the billing file including the requested billing data is completed, the MD proceeds from step 126 to step 128 to generate a sub-process for retransmission of the billing data, and billing the billing file in step 130. Will be resent to the processing unit. The MD then destroys the subprocess generated for retransmission of the charging data in step 132, and then returns to step 104 to perform the steps 104 to 110 while transferring the charging data to the charging processing device. Will be sent online.

However, the conventional CAMA method as described above, which is an online transmission method of billing data, does not properly utilize a function of an exchange designed to improve transmission efficiency by using a plurality of sessions simultaneously, and only when a billing file retransmission request is made from a billing processing device. By creating a new process and using multiple sessions, we did not take advantage of the original multisession usage. In addition, by receiving the billing file, billing file list and billing disk utilization through one main session, it was difficult to manage the data as waiting for the completion of one process and proceeding to the next process. In addition, since the transmission link from the MD to the charging processing device uses X.25, processes for transmitting separate charging data to the charging processing device are required to transfer the charging data using FTAM or FTP. There was a problem of this unnecessary waste.

As described above, the conventional CAMA method does not properly utilize a function of an exchange designed to increase transmission efficiency by using a plurality of sessions simultaneously, and generates a new process only when a request for retransmission of a billing file is made from a billing apparatus. By using, we did not take advantage of the original multisession usage. In addition, receiving a billing file, a billing file list, and billing disk utilization through one main session prevented multiple processes from being performed simultaneously.Therefore, it was difficult to manage data by waiting for one process to finish and then proceeding to the next. . In addition, since the transmission link from the MD to the charging processing device uses X.25, processes for transmitting separate charging data to the charging processing device are required to transfer the charging data using FTAM or FTP. There was a problem of this unnecessary waste.

Accordingly, an object of the present invention is to provide a billing data transmission method in the MD to set up a plurality of sessions to be able to independently process a plurality of billing data at the same time.

According to the present invention for achieving the above object, when the billing relay device collects billing data from the exchange, the billing relay device can receive a plurality of billing data at the same time by creating a plurality of threads and setting a plurality of sessions corresponding to each of the threads. In transmitting the data to the billing device, it is possible to send the billing data directly to the billing device so that the system resource is not wasted due to the creation of a separate process for the billing device. It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings, in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Subsequently, the billing accounting device 206 receives and collects billing data from the exchange 200 through the main session set in step 304, and checks whether one billing file has been received in step 306. In this case, if one charging file is received in step 306, the charging relay device 206 proceeds to step 308 to generate a secondary thread for data transmission of billing data, and the charging in step 310. The file is transmitted to the charging processing device 214.

4 is a flowchart illustrating a process of collecting and transmitting a billing file list in a billing relay according to a request of a billing apparatus according to an embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 4.

First, when the billing file list request is generated from the billing processing device 214 while the billing relay 206 generates a main process and transfers billing data from the exchange 200 to the billing processing device 214 (step 400). In response to this, the process proceeds to step 402 to set up a new session with the exchanger 200 to collect the billing file list, and proceeds to step 404 to generate a secondary thread for billing file list collection and transmission. Unlike the conventional method, establishing a new session is to set a separate new session for collecting a billing file list in addition to the main session set up for collecting billing data, so that each process can be processed separately. Subsequently, the charging relay device 206 collects the charging file list from the exchanger 200 in operation 406, and transmits the charging file list to the charging apparatus 214 in operation 408.

In response to this step (500) in response to this step proceeds to step (502) to set up a new session with the switch 200 for the retransmission of the charging data, and proceeds to step 504 to create a secondary thread for retransmission of the charging data Let's do it. In the setting of the new session as described above with reference to FIG. 4, unlike the conventional method, a separate new session is set up for retransmission of the charging data in addition to the main session set up for collecting the charging data. To be processed. Subsequently, the charging relay device 206 collects the charging file including the charging data required to be retransmitted through the newly established session in step 506 and responds to the completion of the reception of the charging file in step 508. Proceeds to step 510 and transmits it to the billing processing device 214. At this time, unlike the conventional sub-process to generate a charging file collected from the exchange 200 to the charging processing unit 214, in the embodiment of the present invention, the secondary thread for collecting the charging file is independent until the transmission. Will be performed. Subsequently, when the charging file transfer is completed, the charging relay device 206 proceeds to step 512 to destroy the secondary thread.

That is, as in the above-described processes of FIGS. 3, 4, and 5, the billing relay device sets up a new session with the exchange according to each process, creates several sub-threads in one main process, and processes each process. This can be separated and processed independently, and waste of system resources can be prevented.

As described above, the present invention can increase the efficiency of session use between the exchange and the billing relay by setting up a plurality of sessions during billing data transmission / reception, and by creating a thread instead of creating a process for the billing data transmission. There is an advantage that can efficiently use the system resources.
