Description

Matching method between electronic exchange and charging extraction device

The present invention relates to a matching method between an electronic exchange and a charging extraction device (ED).

The accounting extraction device (ED) is a device that extracts the accounting block from the magnetic tape controller and configures the accounting block into a billing file every unit of time (5 minutes) and transmits it to the billing transmission device (TD) via LAN. to be.

Currently, the billing method of the electronic switchboard is Local Automatic Message Accounting (LAMA), which collects billing data generated by the magnetic tape controller on the MT (Magnetic Tape), collects it in the regional billing center, and then collectively arranges the billing data. The LAMA method takes a lot of manpower and time by transporting the produced billing MT by vehicle, and there is a possibility of loss and damage of billing data due to accidents that may occur during transportation. In addition, there is a problem such that it is not possible to configure the daily billing system in the LAMA method is a requirement to provide a new fee-related services.

The present invention has been made to solve the above problems, the exchange information through the CAMA (Centralized Automatic Message Accounting) method that transfers and processes the billing information generated in the electronic exchange using a suitable protocol and transmission medium online The purpose of this paper is to provide a matching method between the electronic exchanger and the charging extraction device which reliably and reliably matches the required exchanger with the CAMA system so as to implement the charging processing function.

In order to achieve the above object, the present invention provides a matching method between an electronic exchanger and a charging extraction apparatus that receives and receives the charging information generated by the electronic exchanger, and collects the charging data from the electronic exchanger in block units. Transmitting to the first step; A second step of adding the charging block extracted for a predetermined period to the end of the generated temporary charging file; A third step of changing the temporary billing file to a normal billing file after generating the temporary billing file and generating a billing data for the next period by newly generating a temporary billing file; And a fourth step of verifying the billing file changed into the normal billing file, storing the billing file in a storage medium, and authorizing the billing transmission device.

The following describes the matching method between the electronic exchange and the charging extraction device.

The billing data created in the electronic switchgear is stored in block units using a memory buffer in the switchboard and dumped to MT. Since there is no hard disk inside the exchange, as soon as the charge block is created, it is transferred to MTU (Magnetic Tape Unit) and written to the MT in blocks. MTU is configured as Active / Standby in case of failure in processing billing data. If a failure occurs in the operating system, the standby MTU is converted into operation and the billing process continues.

The implementation of the CAMA function in the electronic switchboard enables the CAMA function to be performed by adding an external device without changing hardware or software on the exchange side. Here, the newly developed system is composed of three parts, a charge extraction device (ED), a charge transfer device (TD), and a charge collector (HC: Host Collector), each of which is a workstation-class computer. In the conventional LAMA method, MTU used for billing processing was replaced with ED, and ED is extracting billing data by communicating with an exchange in the same manner as MTU. The billing data extracted from ED is transformed into billing files at regular intervals (5 minutes) and transferred to TD. TD transmits billing file received from ED to remote HC. LAN is connected between ED and TD, and packet network is established between TD and HC to communicate through X.25 protocol. In such a configuration, the present invention is a method for changing from the matching method of the existing exchanger and the MTU to the matching between the exchanger and ED in order to implement the CAMA function of the all-electronic exchanger.

Hereinafter, the above description will be described in detail with reference to the accompanying drawings.

Fig. 1 is an exemplary configuration diagram of the matching of an electronic exchanger and a charging extraction device (ED) to which the present invention is applied, and shows an arrangement of the exchanger and the MTU in the conventional LAMA method and the ED matching method for the CAMA method of the present invention. The added structure is compared and shown.

As shown in the figure, conventionally, the output port of the electronic switchboard is composed of three MTUs (15, 16, 17), and two MTUs are operated in an operation / standby structure for charging and another MTU is Used for maintenance.

However, in the LAMA mode, the MTU, which was free to change the functions for maintenance and billing, was replaced with two of the three in the CAMA mode as ED (26, 27), and the two MT controllers (23, 24) connected to it were operated / standby. Set to and use only for charging. The other MTU 25 is used for maintenance.

Figure 2 shows the billing processing method of the CAMA method consisting of ED and TD, showing the overall configuration of the present invention matched with the exchanger, the part shown by the dotted line is the part to which the present invention is applied.

First, the operation / standby ports (101, 102) and ED0, ED1 (103, 104) of the switch MT controller were connected to allow the ED to extract the charging data generated by the MT controller. ED connected to the MT controller of the exchange communicates with the exchange with the same contents as the existing MTU, so that the view from the exchange side remains the same as when using the previous MTU. In addition, two EDs are installed, and each ED is connected to two MT controllers simultaneously so that the same billing can be collected from both EDs. Therefore, whether charging is generated in the MT controller 1 or the MT controller 2, both EDs are received together.

As such, the billing data is preserved in the redundant ED so that it can be referred to when an error occurs in the billing process. The redundant ED exchanges state information with each other using an RS-232C 105 cable, and file transfer is performed by the LAN cable 112 between the redundant ED and the TD.

The TD is then sent to the HC 113 at the remote charging center using the X.25 (111) network.

3 is a flowchart illustrating an example of a matching method between an exchange and a charging extraction device according to the present invention. After the charging data generated in the MT controller is transferred to the redundant ED and transformed into a charging file through a multi-step procedure, FIG. It shows the process transmitted to TD.

As shown in Fig. 2, the two EDs are duplicated to perform the same processing internally.

The magnetic tape emulator (MTE) of the first charging extractor (ED0) is connected to the MT controller 201 of the exchanger to extract the charging data, and the manual data collector (PDC) of the ED1 is connected to the same line. Passive Data Collector is connected to collect data extracted by the MTE 203 in the same manner. The waiting MT controller 202 is connected with the MTE of ED1 and the PDC 204 of ED0. If a failure occurs in the MT controller 201 in operation and the operation-waiting is switched in a redundant structure, the MT controller 202 waiting in the standby state operates as an operation state and the uninterrupted charging data is not lost. Collection is possible. Collected billing data is sent to ED in a block unit and continues to be collected in a temporary file for 5 minutes (205, 206). The billing blocks transmitted through the MTE and the PDC are stored as temporary files in different EDs and transformed into billing files every 5 minutes (210, 212). The created billing file is stored in the ED's hard disk (213). After checking whether the billing data generated in both EDs are the same, the billing file of the ED set as the subject of transmission is transmitted to the TD (214).

As described above, the present invention can be applied for billing processing of AXE-10 IOG3 exchanger, No.5 ESS exchanger, No.1A exchanger and AXE-10 IOG11 exchanger.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

According to the present invention, the charging information generated by the exchange is transmitted and processed online using a proper protocol and a transmission medium, eliminating the possibility of loss and damage of the charging data, and reducing the waste of time and manpower. There is.
