Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 shows a connection diagram between an electronic exchanger and a charging collector using the present invention.

In order to guarantee the reliability of the system due to the nature of the exchange, the present invention is configured with redundancy, and the redundant charging intermediary devices 2 of the present invention are provided through a local area network (LAN), and the operation maintenance processor of the redundant exchange is provided. It is connected to the message command control interface assembly (MCIA) located in each of the (OMP: Operation and Maintenance Processors) 11 and 12.

In addition, the present invention is connected to the central automatic message accounting (CAMA) packet network (3) through the X.25 card, the CAMA packet network (3) is connected to the billing device (4).

In addition, the RS-232C is connected between the redundant billing mediators, and each billing mediator has two LAN cards to be combined with all the redundant operational maintenance processors of the exchange.

2 is a block diagram of a charging intermediary apparatus according to the present invention, in which "21" is a LAN interface unit, "22" is a system state management unit, "23" is a common memory, "24" is a charge extraction redundancy control unit, "25" is a charging block receiving unit, "26" is a charging block redundancy processing unit, "27" is a hard disk (HDD), "28" is a transmission redundancy control unit, "29" is a charging file management unit, "30" is a charging transmitter "31" is X.25 interface, "32" is X.25 client, "33" is X.25 server, "34" is RS-232C interface, "35" is statistical data and alarm collection, "36" denotes a backup processing unit and "37" denotes a digital audio tape (DAT).

The LAN interface unit 21 is for connecting to the operation maintenance processor of the exchanger, the counterpart charging intermediary device and the LAN cable. The LAN interface unit 21 receives the charging information from the exchanger or activates an active mode for data correspondence between the redundant devices. ), The charging intermediary device performs an access function for transmitting the charging information received from the exchange to the charging mediator in the inactive mode (Standby). In addition, a control signal for controlling the duplication operation is also transmitted and received via the LAN interface unit 21.

The system state management unit 22 checks the states of the processes and devices existing in its apparatus with the system startup, and stores the result in a specific area of the shared memory 23.

The billing extraction redundancy control unit 24 receives a state grasping request from the electronic switchboard periodically (2 seconds). Accordingly, the system state management unit 22 reads its own state information stored in the shared memory 23 for LAN interface. The unit 21 transmits the data to the counterpart accounting intermediary device. And, through the same process to determine the activation or deactivation mode for the own system with reference to the partner state information received from the counterpart charging intermediary device, and if the self-activated mode at the same time storing the determined result in the shared memory (23) Sends status information along with LAN address information to the exchange.

The duplication operation mode is determined through the above-described process of the charging extraction redundancy control unit 24, and the activation mode side charging extraction redundancy control unit 24 controls the charging block redundancy processing unit 26.

The charging block receiver 25 performs slightly different operations according to the activation mode and the deactivation mode. First, in the activation mode, the charging block receiving unit 25 stores the charging block received from the exchange through the LAN interface unit 21 in the memory area for processing the charging block of the hard disk (HDD) 27 and at the same time deactivates the charging block. It is also stored in the redundant memory area for transmission to the counterpart accounting intermediary device. Here, when the charging block receiving unit 25 stores the received charging block in the charging block processing memory area, a corresponding file is separately generated in an arbitrary time unit (5 minutes) according to the end time of the call included in the received charging block. Save it. For example, a charge block whose call end time is from 00: 00: 00 to 00: 04: 59 is stored as a file name, and the call ends of the call included in the received charge block. The charging block whose time is from 00:05:00 seconds to 00:09:59 seconds is stored in one file name different from the above file name. Through this process, the billing information that was called on the same day is stored in a total of 288 files.

The billing block receiving unit 25 verifies the sequence number of the billing block and the continuity of the billing file generation when the billing file generation for the billing block received through the above process is completed, and if there is no error, the hard disk 27 The billing file generated in the billing block processing memory area is read and stored in the memory area for transfer of the billing file in the same hard disk 27.

The charging block receiving unit 25 on the inactive mode side receives the charging block from the charging intermediation device on the active mode side, and the rest is the same except for storing the received charging block in the redundant memory area in the above-described operation description. It works.

The charging block redundancy processing section 26 continuously monitors the redundancy memory area in the hard disk 27 and reads the charging block as soon as it is stored and transmits it to the charging intermediary device in the inactive mode side through the LAN interface section 21. As a result of this operation, upon receiving the response signal indicating that the receiving device is normally received from the charging intermediation device on the inactive mode side, the transmitted charging block is deleted from the redundancy memory area, and upon receipt of the response signal indicating that the reception state is abnormal, retransmission is received. Do this. If no response is received and there is a charging block above the threshold in the redundant memory area, the charging block stored in the redundant memory area is merged into an arbitrary time unit (one hour) file.

The charging block redundancy processing unit on the inactive mode side is stopped by the charging extraction redundancy control unit.

The present invention is configured to separately perform a redundancy control by separating a portion for receiving and processing a charge block and a portion for transmitting the processed charge block to a charge collection device. In this way, if the charging intermediary device in the activation mode receives the charging block from the exchange, but the failure of the X.25 transmission path connected to the charging collector occurs, the transmission related part of the inactive mode is set to the active mode, and through this, the collection process is performed. The processed charging block can be sent to the device.

The function unit that performs such transmission-related redundancy control is the transmission redundancy control unit 28.

The transmission redundancy control unit 28 accesses the common memory 23 to grasp its own state, and transmits status information to each other with the transmission redundancy control unit 28 of the counterpart charging intermediary device through the RS-232C interface unit 34. To determine the redundant operation mode. Here, if there is no obstacle on the transmission link for the accuracy of the data transmitted to the billing device, the billing device in which the billing block receiver 25 operates in the activation mode also operates the transmission related functions in the activation mode.

When the duplication mode of the transmission duplication control unit 28 is determined through the above process, the transmission duplication control unit 28 controls the transmission related processes. That is, the transmission duplication control unit 28 performs a function of starting, stopping, or restarting transmission related processes.

Here, the transfer-related function unit includes a billing file manager 29, a billing transmitter 30, an X.25 client 32, an X.25 server 33, and the like.

The billing file manager 29 notifies the billing transmitter 30 of the billing file information, which is not completed, among billing files stored in the billing file transmission memory area in the hard disk 27 when the transfer related function is in the activated mode. do. Then, when notified that the corresponding charging file is normally transmitted from the charging transmitter 30, the transmitted charging file information is transmitted to the counterpart (deactivation mode) charging broker. Then, the charging file management unit 29 on the activation mode side and the inactivation mode side reads the transferred charging files and writes them to the backup memory area in the same hard disk 27.

In addition, the billing file manager 29 sends a billing file to the billing unit 30 when the state of the billing file which has been requested to be transmitted is received when a mandatory transfer command of a billing file from the operator or a retransmission request is received from the billing device. Pass the transfer command. In this case, when the transmission is impossible, the charging file manager 29 outputs the cause of the failure to transmit to the operator or transmits the cause message of the impossible transmission to the charging collector.

When the billing transmission unit 30 is notified of the billing file to be transmitted from the billing file management unit 29, the billing file is read from the billing file transfer memory area in the hard disk 27 and collected through the X.25 interface unit 31. To the device. As a result of this, upon receiving the response signal according to the reception of the charging file transmitted from the charging collector, the received response signal is transmitted to the charging file manager 29.

The X.25 interface 31 is an X.25 card for connecting with the charging device.

The X.25 server 33 receives the message transmitted from the billing device through the X.25 interface unit 31 and delivers the message to the X.25 client 32.

The X.25 client 32 transmits a message to be sent to the charging apparatus through the X.25 interface unit 31 according to a request of the charging apparatus received through the X.25 server 33, or statistical data and alarms. When the emergency alert message is received from the collector 35, it is transmitted to the billing device through the X.25 interface 31.

The statistical data and alert collection unit 35 receives data necessary for the history management of the system from the charging block receiving unit 25 and the charging transmitting unit 30 to generate statistical data of unit of time, daily unit and monthly unit to generate hard data. Store in a specific area of disk 27, or send an alert message from each processor or device to X.25 client 32.

The backup processing unit 36 finds the transferred data from the charging file transfer memory area in the hard disk and backs it up to the digital audio tape (DAT), and the file for which the storage period required by the operator has elapsed among the files already backed up. If present, it is deleted from the memory area for billing transfer in the hard disk.

3 shows a process flow diagram at an exchange for charging block transmission in accordance with the present invention.

The charging collection mode is entered from the console of the exchange at the request of the operator.

When the charging collection mode is determined through the above process, the operation maintenance processor retrieves a charging block of 14 blocks from the disk in the exchange (101). Then, one block is read from the memory (102), the charging header is added to the one charged block (103), the charging block to which the charging header is added is divided into three (104), and then transferred to each of the three divided charging blocks. A header (block number, billing number, subblock number, and dummy) is added (105) to transmit the billing block (transport block) to which the transport header is added to the billing intermediary device in the active mode over the LAN. (106).

After all 14 blocks read from the disk in the exchange are transferred (107), the transfer result is read from the LAN (108) and the transfer result is checked (109).

If the transmission result received from the charging intermediary device in the activation mode is normal, the new 14 blocks of charging data are retrieved from the disk again and the above process is repeated. If the transmission result is abnormal, the 14 blocks of charging data are retransmitted. 110).

Here, if two redundant charging brokerage devices are abnormal, the operation maintenance processor (OMP) stores the billing data on the billing disk for CAMA in the exchanger, and automatically automatically activates the charging brokerage mode when the charging brokerage device is restored. To the device. If the billing intermediation device is not restored even if the CAMA billing disk in the exchange is full, the billing mode is automatically changed to the country billing method.

4A and 4C show a processing flowchart for charging mediation in the charging mediation apparatus according to the present invention.

The charging intermediary device in the active mode reads the charging block transmitted from the exchange through the LAN device (201), analyzes the transmission header, and stores the buffer in the buffer unit according to the result (202). After receiving all 14 blocks through this process (203), if the received charging block is normally received without abnormality, the transmission result is notified to the exchange as normal (204), otherwise, if there is an error, it is transmitted to the exchange. The result is notified abnormally (205).

First, the charging block received through the LAN is stored in the charging block processing memory (206), and at the same time, the charging block received through the LAN is stored as a charging block file in the duplication memory (207).

The billing block file stored in the duplication memory is immediately transferred to the billing intermediary device in inactive mode via the LAN (208). Then, as a result of receiving the message indicating that the charging block file has been normally transmitted from the charging intermediary device in the inactive mode (209), after deleting the charging block file transmitted from the redundancy memory to the charging mediation device in the inactive mode (210). Then transfer the next billing block file. If a message indicating that the transmission result is abnormal is received from the charging broker in the inactive mode, the corresponding charging file is retransmitted, and no response is received as a result of the retransmission, and if there are more than 10 charging block files stored in the redundancy memory for 1 hour The charging block file stored in units is merged (211).

On the other hand, the charge block stored in the charge block processing memory is generated and stored in one file every 5 minutes according to the call termination time. When the charge file generation is completed for 5 minutes for the received charge block through this process (212), the sequence number of the charge block and the continuity of the charge file generation are verified, and if there is no error, the charge file is transferred to the charge file transfer memory. Move (213).

The process in charge of managing the transfer of the billing file requires the transfer process to transfer the billing file which is not transferred to the billing device among the billing files stored in the billing file transfer memory (214), so that the transfer process transfers the file forwarding and access management (FTAM). It uses the File Transfer Access and Management protocol to transmit the data to the billing device through the X.25 packet network (215).

Accordingly, the transmission result received from the charging collector is checked (216). If the transmission result is abnormal, the corresponding charging file is retransmitted (217). If the transmission result is normal, the information of the charging file which has been transferred is deactivated. As a result, the process in charge of the transfer management of the billing file of the billing mediator in the activation mode and the inactive mode reads the billing file from the billing file transfer memory and stores it in the backup memory (218).

On the other hand, if a forced transfer command of a billing file is received from an operator or a request for retransmission is received from a billing device, the billing file that is requested to be transferred is transmitted if possible, and if it is impossible, it cannot be sent to the operator. Print the cause or send the cause message that cannot be sent to the accounting device.

The process in charge of the backup finds the files not backed up among the billing files stored in the backup memory and backs them up to the digital audio tape, and deletes the files in the backup memory that have already passed the storage period required by the operator (219). .

For reference, the billing mediator and the bill collector use the FTAM protocol to transfer billing files and the X.25 protocol to send system status and alert messages.

In addition, a message to be transmitted to the billing device during operation in the CAMA billing mode (for example, a retransmission response message indicating whether or not the request for retransmission of the billing file required by the billing device can be transmitted, periodically or at the request of the operator). Response message informing the request of transmission of status information of the charging intermediary device, response message to the periodic operation control message of the charging intermediary device, switching of the charging intermediary device or identifier (ID) of the charging intermediary device and X.25 address In case of change, alerting and recovery message of billing broker), X.25 client attempts to connect with billing device and if successful, sends message to billing device using X.25 protocol. If it fails, try to connect again. If the maximum number of attempts is exceeded, a new message is received and sent to the billing device. In addition, a message transmitted from the billing device using the X.25 protocol (for example, an operation control message for confirming the normal operation state of the billing intermediary device periodically transmitted from the billing device, an operator's request or billing) Message requesting to send status information of billing intermediary device sent at periodic request of device, message requesting retransmission of billing file to billing mediator after verifying billing file of billing device, system identifier (ID) or X of billing device .25 Messages that inform the billing broker if the address changes are received by the X.25 server.
