The present invention relates to the charging data collection of the exchange system, and more particularly, to a centralized charge collection method in the exchange system to collect the charging data generated from a plurality of exchangers operated unattended to the central exchange system in real time.

In general, an exchange that is operated automatically without an operator has its own billing information collection device, so that subscribers can read and store billing information such as distance and call time of the called party when the subscriber calls outside, but more billing is required. Since it is not equipped with the information processing function, it is necessary to send the collected billing information to the analysis place whenever necessary to notify subscribers of the phone bill. Local charging method and centralized charging method are used. The system to which the local charging collection method is applied includes a plurality of independent remote branch exchange systems (IPBX1 to n), a plurality of upper station remote branch exchange systems (HPBX), and a plurality of sub station remote branch exchange systems (LPBX), as shown in FIG. , A plurality of billing apparatuses MT1 to n, and a central billing processing place 100. Independent remote switch system (IPBX1 ~ n), host station remote switch system (HPBX), and lower station remote switch system (LPBX) are each connected to multiple subscribers to calculate billing data when subscribers call outside It sends out to apparatus MT1-n side. The charging recorders MT1 to n are connected to the independent remote branch exchange system 1PBX1 to n, the host station remote branch exchange system (HPBX), or the subordinate station remote branch exchange system (LPBX), respectively, to collect the charging data supplied from the corresponding exchange system. It has the function of receiving and storing. It records and stores the billing data on the magnetic tape. When it is time to notify the subscriber, the billing data of the billing device (MT1 ~ n) is collected and transported to the central billing processing place (100). The central billing processing place 100 performs a series of tasks for notifying the subscriber of billing such as reading, analyzing and processing the transported billing data.

As shown in FIG. 2, the system to which the centralized charging balance method is applied includes an independent remote branch exchange system (1PBX1 to n), a higher station remote branch exchange system (HPBX1 to n), a lower station remote branch exchange system (LPBX1 to n), The billing collection device (LCA1 ~ n), the central billing collection device 200, and the central billing processing place (300). Independent remote switching system (IPBX1 ~ n), upper station remote switching system (HPBX1 ~ n), and lower station remote switching center system (LPBX1 ~ n) are each connected to multiple subscribers to receive billing data when the subscriber calls out. It calculates and sends it to the billing collection apparatus LCA1-n side. The charging collectors LCA1 to n each receive and store the charging data sent from the corresponding exchange system, and when the charging data transmission permission message sent from the central charging collector 200 is received, the charging data stored in the dial data is dialed. It is sequentially sent to the central billing collection unit 200 through a data link (Dial Up Date Link) or a dedicated line. The central billing collection device 200 receives the billing data sent from the billing collection devices LCA1 to n through a dial data link or a dedicated line, and sends the billing data to the central billing processing site 300, and the central billing processing site 300. Receive the billing data transmission message sent from the) and supplies it to the billing collection device (LCA1 ~ n) side. The central billing processing place 300 forms a billing data transmission message at predetermined time intervals, sends the billing data transmission message to the central billing collection device 200, and receives and analyzes and processes the billing data sent from the central billing collection device 200. Performs a series of tasks to notify the subscribers of the charges.

The local charging method in the exchanger as shown in FIG. 1 may be lost while transporting the billing data to the central billing processing location 100, and the billing recording device storing billing data ( Due to the magnetic tape MT1 ~ MTn), if the magnetic field is strongly formed during transportation, the billing data may not only be deteriorated but also the billing data may be expensive.

In addition, the centralized charging collection method as shown in FIG. 2 described above requires a large amount of installation costs because the charging collectors LCA1 to LCAn must be provided for each exchanger, and the charging data from the central charging collector 200 is charged. Due to the protocol of the system that allows the billing data to be transmitted only when a transmission permission message is supplied, real-time processing of billing data is impossible, and the data transfer rate is limited to 4.6kbps or 54kbps for rapid data transfer. And the lower station remote switching system (LPBX1 to LPBXn) and the upper station remote switching system (HPBX1 to HPBXn) cannot supply the charging data to the central charging collecting device 200 using the same data link. The remote branch exchange system (LPBX1 to LPBXn) and the host station remote branch exchange system (HPBX1 to HPBXn) are connected to the central charging collector 200. The data link installation cost is high because the data related to the billing process is exchanged with each other through direct data link, and the existing data link connecting the lower station remote switching system and the higher station remote switching system is used. Because of the inability to send and receive data related to billing processing, there was a problem in that efficient link usage cannot be expected.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a lower station exchange system using an existing data link connecting a lower station exchange system and a higher station exchange system and a link connecting a higher station exchange system and a central exchange system. By enabling the central exchange system to send and receive data related to the charging process, it improves the efficiency of the data link, increases the transmission speed, calculates the charging data at the remote exchange system and simultaneously sends the data to the central exchange system for charging in real time.

LPBX1-n, a central exchange system 400, and a central charging collector 500. Independent remote switching system (1PBX1 ~ n), higher station remote switching system (HPBX1 ~ n), and lower station remote switching center system (LPBX1 ~ n) are each of four switching devices (EU1-4) as shown in FIG. ), A billing data processing device 600, a local billing collection device 800, a billing data transmission link device 700, and a printer 900. Switching devices EU1 to 4 are connected to the subscriber, and when the subscriber attempts to complete an external call and completes, the charging data including the message length, the corresponding exchange number, the message classification code, the charging data, and the block check code. Calculates and sends the billing data transmission request message to the billing data processing device 600, and then receives the billing data transmission permission message sent from the billing data processing device 600 to the billing data processing device 600. Send it out. The billing data processing device 600 receives the billing data sent from the four exchange devices EU1 to 4, stores the billing data therein, stores it in a queue, codes the received billing data, and blocks the block inspection code. After checking whether there is an abnormality and processing a packet in units of 16 bytes, the charging data transmission request message is sent to the charging data transmission link device 700 and the charging data transmission permission message is received. When the billing data is sent to the device 700 and a message is received from the billing data transmission link device 700 informing that the link has failed, the switching device EU1 to the next time when the queue of the full body becomes full. The billing data sent from 4) is sent to the local billing collection device 800 or the printer 900 side. The local charging collector 800 has a function of receiving and storing the charging data sent from the charging data processing apparatus 600, and the printer 900 receives the charging data sent from the charging data processing apparatus 600. Output it. The billing data transmission link device 700 determines that an abnormality has occurred in the data link or the central switch system 400 if a billing data transmission permission message is not supplied even after a predetermined time has elapsed from the central exchange system 400. When receiving the charging data transmission request message sent from 600, a message indicating that an abnormality has occurred is sent to the charging data processing apparatus 600, and the charging data transmission permission message sent from the central exchange system 400 is predetermined. If the charging data transmission request message sent from the charging data processing apparatus 600 is received within the time, the charging data transmission permission message is sent to the charging data processing apparatus 600, and then, from the charging data processing apparatus 600. Receives billing data sent and uses central link And it sends out the side of the stem (400). The central exchange system 400 checks the link connecting the remote switching system (IPBX1 ~ n, HPBX1 ~ n, LPBX1 ~ n) and determines whether there is an error, and then charges data transmission link device 700 when there is no error in the link. When the billing data transmission request message sent from the billing data transmission permission message is sent, the billing data transmitted from the billing data transmission link device 700 receives and analyzes the billing data sent to the central billing collection device 500 side. . The central billing collection device 500 has a function of receiving and storing billing data sent from the central exchange system 400. The central exchange system 400 is comprised of a remote exchange charge collection data link device 410, a remote exchange charge collection device 420, and a central charge device 430, as shown in FIG. 5. The remote switching unit billing collection data link device 410 always checks the data link to determine whether there is an abnormality, and if there is no link link, the billing data transmission request message sent from the billing data transmission link device 700 is transmitted. Upon receipt, the billing data transmission permission message is sent to the billing data transmission link device 700, and the billing data sent from the billing data transmission link device 700 is received and sent to the billing device 420 of the remote exchange switch. The remote exchange billing collection device 420 receives the billing data sent from the remote exchange billing collection data link device 410 and blocks the billing data every time 10 billing data is collected to convert one billing data format. If the response signal sent from the central charging device 430 is not received even after a predetermined time has elapsed after transmitting to the central charging device 430, the blocked charging data is retransmitted, and if the response signal is received within the predetermined time, the corresponding charging Recognize that the data transfer process is complete and perform the following steps.

The central billing device 430 is connected to the subscriber of the central exchange system 400 to calculate the billing data within itself and to send it to the central billing collection device 500 side, as well as to block the billing sent out from the remote exchange billing device 420. Receives billing data and sends it to the central billing collection device 500 side and at the same time sends a response signal to the remote exchange exchange billing collection device 420 side.

6 is a flow chart for centralized collection of charges in a remote exchange system according to the present invention. As shown here, when a subscriber completes a call to the outside, the exchange devices EU1 to 4 display a message length, an exchange device number, and a message classification. Calculates billing data including a code, a billing data, and a block check code, sends a billing data transfer request message to the billing data processor 600, and sends billing data from the billing data processor 600; When the permission message is received, it is sent to the calculated billing data processing device 600 side. At the beginning of system operation, the charging data processing device 600 is set to be operated by the operator by the centralized charging collection method, and when the charging data transmitted from the exchange devices EU1 to 4 is received (step S1). The operator sends the charging data to the central exchange system 400 side, whether or not the first transfer mode allows the data to be collected only by the central exchange system 400 by using the software embedded in the user to recognize the desired centralized charge collection mode. In principle, but if the link is abnormal, whether or not in the second transmission mode to collect the charging data to the local charging device (800) side, whether charging data simultaneously to the central exchange system 400 and the local charging device (800) side Is sequentially determined whether or not the third transmission mode is to be collected, and recognizes the set lumped charging collection mode ( Step S2, step S12, step S22). If it is determined in step S2 that the first transmission mode is the first, the charging data processing apparatus 600 packets the message in units of 16 bytes via a parallel bus on which the charging data transmission link apparatus 700 is mounted. In this case, a packet serial number indicating the order of the transmitted messages, a code indicating a corresponding billing data transmission link device 700, a message classification code, billing data information, and a block check code are included. After the billing data is calculated, the billing data transmission request message is sent to the billing data transmission link device 700 at a predetermined time interval, and if the billing data transmission permission message sent from the billing data transmission link device 700 is received within a predetermined time. It is determined that the link state is normal (step S3), and the calculated billing data is stored in a local queue provided in itself (step S4), and stored in the local queue. The stored charging data is sequentially sent to the charging data transmission link device 700 (step S5). The billing data transmission link device 700 receives the billing data sent from the billing data processing device 600, and then determines a final destination code of the corresponding message, a message classification code indicating whether the message type is billing data, and a memory total length. Message length divided by the number of messages, identification (ID) code of the remote exchange system that sent the message, and identification of the higher station, respectively, if the corresponding remote exchange system is the upper station remote exchange system or the lower station remote exchange system. Calculate the billing data including the code and the sub-station identification (ID) code, the billing data information, and the block inspection code. If the charging data transmission link device 700 belongs to the lower station remote switching center systems LPBX1 to n, the charging data is transmitted to the charging data transmission link device 700 side of the predetermined upper station remote switching center system HPBX1 to n. When the billing data transmission permission message sent from the billing data transmission link device 700 of the host station remote branch exchange system (HPBX1 to n) is received within a predetermined time by sending a request for transmission, the billing data calculated is transferred to the corresponding station of the remote station. It is sent to the billing data transmission link device 700 side of the system (HPBX1 ~ n) to be supplied to the remote exchange billing collection data link device 410 of the central exchange system 400. If the billing data transmission link device 700 belongs to the host station remote branch exchange system (HPBX1 ~ n) or the independent remote branch exchange system (IPBX1 ~ n), the remote branch exchange charging collection data link device of the central exchange system 400 ( The charging data is transmitted to the 410 side by the protocol described above (step S6). If the billing data transfer permission message sent from the billing data transfer link device 700 is not received even after a predetermined time elapses after the billing data processing device 600 sends the billing data transfer request message in step S3, the link is abnormal. It is judged that this has occurred, and it is judged whether or not the local queue provided in itself is in a full state full of data (step S7). If it is determined that the local queue is not in the full state, the calculated charging data is stored in the local queue (step S9), and when the link state is changed to normal, the charging data is transmitted to the charging data transmission link device 700 in order. If it belongs to (LPBX1 to n), the charging data is sent to the charging data transfer link device 700 side of the host station remote branch exchange system (HPBX1 to n) (step S10), and the host station remote branch exchange system (HPBX1 to n). If the charging data transmission link apparatus 700 determines that there is an abnormality in the link by receiving the charging data and determining whether there is an error by the designated charging data transmission / reception protocol method, the remote switching center of the central exchange system 400 is charged. The data is sent to the collection data link device 410 side (step S11). However, if the subject in step S9 is the billing data processing apparatus 600 belonging to the host station remote switching center system HPBX1 to n or the independent remote switching center system IPBX1 to n, step S11 is obtained without passing through step S10. Will be done. If it is determined in step S7 that the local queue is in the full state, the calculated data is supplied to the printer 900 and outputted (step S8).

If it is determined in step S2 that the mode is not the first transfer mode, it is checked whether or not the transfer mode is the second transfer mode (step S12). If it is determined that the second transmission mode is the second transfer mode, the charging data processing apparatus 600 performs step S13, which is the same process as step S3. If it is determined in step S13 that the link state is normal, step S14, step S15, and step S16, which are the same processes as step S4, step S5, and step S6, are sequentially performed. If it is determined in step S13 that an abnormality has occurred in the link state, step S17, which is the same process as in step S7, is performed. If it is determined in step S17 that the local queue is not in a full state, the step S9, step S10, and step S11 are respectively performed. Steps S18, S19, and S20, which are the same process, are sequentially performed, and if it is determined in S17 that the local queue is in a full state, the charging data processing apparatus 600 sends the charging data to the local charging collector 800. (Step S21). On the other hand, if it is determined in step S12 that the second transmission mode is not adopted, it is determined whether or not the third transmission mode is adopted (step S22). If it is determined in step S22 that the third transmission mode has not been adopted, it is assumed that an abnormality has occurred in the system, the system is diagnosed, and appropriate measures are taken. Step S32, which is the same process as step S21, is performed at the same time as step S23 is performed. If it is determined in step S23 that the link state is normal, steps S24, S25, and S26, which are the same processes as the steps S9, S10, and S11, are sequentially performed. However, if it is determined in step S23 that there is an error in the link state, step S27 which is the same process as step S7 is performed. If it is determined in step S27 that the local cue is in a full state, step S28 is performed, which is the same process as in step S8. If it is determined that the local cue is not in a full state, the same process as each of steps S9, S10, and S11 is performed. Step S29, step S30, and step S31 are performed sequentially.

As described above, the charging data transmission link device 700 of the remote switching system (IPBX1 to n, HPBX1 to n, LPBX1 to n) transmits the charging data to the central switching system 400 side. n, HPBX1 ~ n, LPBX1 ~ n) If the centralized charge collection procedure is completed, the centralized exchange system 400 to complete the centralized collection process, the centralized charge in the central exchange system 400 according to the present invention The collection process will be described with reference to FIG. 7.

When the message is received, the billing data transmission permission message is sent to the billing data transmission link device 700, and the independent remote switching system (IPBX1 to n), the upper station remote switching system (HPBX1 to n), and the lower station remote switching center system ( The charging data transmitted from LPBX1 to n are received (step S100). Then, if the billing data received by the remote exchange billing data link device 410 is sent to the remote exchange billing device 420, the remote exchange billing collecting device 420 stores the billing data until 10 billing data are collected. (Step S200), when 10 charging data are collected, the final destination of the message, the message classification code, the message length, the confirmation code of the corresponding remote exchange system that sent the charging data, the transmission number indicating the number of times the charging data was transmitted, 10 The charging data including the charging data information and the block inspection code, which are bundled into one block by blocking the charging data information, are calculated and sent to the central charging device 430 (step S300). The central billing device 430 calculates the billing data in itself and sends it to the central billing collecting device 500 side, and also receives the blocked billing data sent from the remote exchange billing device 420 to collect the central billing device 500. Is sent to the () side (step S400).
