Abstract

The present invention relates to a billing processing method of an exchange system, and more particularly, to a billing processing method of an exchange system to transfer the billing stored in the MT to the billing clearinghouse directly through Transmission Control Protocol / Internet Protocol (TCP / IP).

In the conventional switching system, when the subscriber's call is terminated, the billing history of the completed call is stored in the main memory and the auxiliary memory, and the billing disk in which the billing data block for transmitting the billing data block is transmitted abnormally among the auxiliary memory devices. If it is stored in the MT, which is another auxiliary memory device in a normal state, the billing data stored in the MT has a disadvantage in that it cannot be directly transmitted online through the billing settlement.

According to the present invention, after storing a start and end number of a billing data block that is not stored in a corresponding billing disk due to an abnormality of the billing disk, in the local MT information, the MT stores the billing data of the billing magnetic disk in the local MT information. Read it and save it in the header. If the billing disk is normally restored, MT stores the billing data that is not stored in the restored billing disk in the form of a temporary file, and if the billing disk is not restored normally, the billing data that is not stored in another billing disk is stored in the form of a temporary file. When the billing data center requests billing data transmission, the billing data in the form of temporary files stored on the billing disk can be transferred directly through TCP / IP, thereby quickly and inexpensively transferring billing data stored in the MT to the billing clearing house.

Description

Billing Processing Method in Switching System

The present invention relates to a billing processing method of an exchange system, and more particularly, to a billing processing method of an exchange system to transfer the billing stored in the MT to the billing clearinghouse directly through Transmission Control Protocol / Internet Protocol (TCP / IP).

In general, the billing function in the exchange system generates billing data that can be used to calculate the billing for the call service provided by the subscriber and records it on the magnetic tape (MT). In order to do this, the billing data generated per call is processed in a block unit to be processed in real time, and the temporary storage of billing data using the billing disk minimizes data loss and enables data retrieval.

On the other hand, the charging processing apparatus of the conventional exchange system, as shown in the accompanying drawings, Figure 1, the call processing unit 11, the charging processing unit 12, the charging memory unit 13, the charging disk 14 and the MT ( 15).

The call processing unit 11 transmits detailed billing information on the completed call to the billing processing unit 12 through IPC (Inter-Processor Communication), and the billing processing unit 12 from the call processing unit 11. Receive detailed billing information, process the data into a form of billable data, store it in the billing memory unit 13, store it in the billing disk 14 and the MT 15, and store billing data stored in the billing disk 14. Read and send to billing settlement via TCP / IP.

The billing memory unit 13 temporarily stores billing data in units of blocks as a main memory, and serves as a temporary billing block storage for storing the billing disk 14 and the MT 15, which are actual storage media.

The accounting disk 14 stores a billing data block for transmission to the billing clearing house as an auxiliary storage device.

The MT 15 is an auxiliary memory device and is allocated for charging in the active and standby states. The active state stores the charging history occurring in the current exchange system, and the standby state is the active state. When the charge storage is completed in the MT (15), it is a standby state in which it becomes active and can store the charge details.

The charging processing operation of the conventional exchange system configured as described above will be described in detail as follows.

First, when the detailed billing information for the completed call from the call processing unit 11 is transmitted to the billing processing unit 12 through IPC, the billing processing unit 12 receives the detailed billing information and processes it into data in a chargeable form. The primary memory device is stored in the charging memory unit 13, which is a main memory device, and stored again in the secondary storage device, the charging disk 14 and the MT 15. In this case, the chargeable data, that is, the charging data is stored. For the sake of convenience, the unit is configured as a block unit, which is the minimum storage unit of the exchange system. One billing data block (1K byte) is composed of 7 billing records (1 billing record size = 144 bytes) and block information.

That is, the billing processing unit 12 processes the detailed billing information transmitted from the call processing unit 11 and when one billing data block is configured, stores the billing data in the billing memory unit 13 first, and then stores the billing data. Check the charging disk 14 for abnormality.

At this time, when the charging disk 14 is normal, the charging processing unit 12 stores the charging data block stored in the charging memory unit 13 in the charging disk 14, and the charging data block stored in the charging disk 14. The dump is dumped to the MT 15, and 30 charging data blocks are dumped to the MT 15 as a basic unit.

By the way, when the charging disk 14 is abnormal, the charging processing unit 12 stores the charging data block stored in the charging memory unit 13 in the charging memory unit 13 without storing the charging data block in the charging disk 14. When the number of stored billing data blocks exceeds the threshold, Lost Call processing is performed to convert the billing data blocks into status messages and output them to the operator terminal.

Here, the storage capacity of the charging memory unit 13 is 600K bytes, and can store up to 600 charging data blocks, and in the case of the current exchange system, '2/3 (400K bytes)' of the maximum storage capacity is set as a threshold. If 400 billing data blocks are stored in the billing memory unit 13, the billing memory unit 13 outputs the billing data blocks to the operator terminal in the form of a status message.

The lost call refers to a storage space for a charging data block that occurs after a charging data block having a threshold value or more is stored in the charging memory unit 13 at the time when an abnormality of the charging disk 14 that is an auxiliary memory device is detected. It means to output the pre-stored billing data block to the operator terminal to secure it.

On the other hand, the billing data generated by the exchange system is collected online at the billing clearing house through the X.25 or Transmission Control Protocol / Internet Protocol (TCP / IP) for quick calculation of the charge, and the exchange system collects the billing data. Since it acts as a client for the transmission, the billing data can be transmitted only when a billing data transmission request is made at the billing settlement office.

In addition, the charging data transmission through the online targets only the charging data stored in the charging disk 14, and the charging data corresponding to the detailed charging information is stored in the charging disk 14 due to the abnormality of the charging disk 14. If not, the billing data is stored in the MT 15, and the billing data stored in the MT 15 cannot be transmitted to the billing settlement online. There was a problem that you have to take it off and carry it to the billing settlement.

The present invention is to solve the problems described above, the object of the check, in the exchange system check whether the charging disk is abnormal, if it is determined that the charging disk is abnormal state, MT is not stored in the charging disk in the local MT information If the billing disk is normally recovered by reading the billing data and storing the billing disk normally, the unsaved billing data is stored in the billing disk as a temporary file, and if the billing disk is not recovered normally, it is saved as a temporary file in another billing disk TCP / IP By transmitting to the billing settlement through the bill, it is to transfer the billing data stored in the MT to the billing settlement in a quick and low cost.

Billing processing method of the exchange system according to the present invention for achieving the above object, the process of receiving the detailed billing information for the completed call to process the billing data and storing in the billing memory of the main memory in block units (a) )and; Checking the state of the charging disk used as an auxiliary storage device for transferring the charging data block stored in the charging memory to the charging settlement and if the charging disk is found to be abnormal, charging the charging data block stored in the charging memory. (B) storing only the MT without storing the disk; (C) transmitting a billing data block normally stored in the billing disk to a billing settlement station and transmitting a billing data block stored in the MT and not stored in the billing disk when the billing data transmission request from the billing settlement is requested. Characterized in that it comprises a. Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

The charging processing apparatus of the exchange system according to the present invention has a call processing unit 21, a charging processing unit 22, a charging memory unit 23, a charging disk 24 and In this case, the call processing unit 21, the charging memory unit 23, and the charging disk 24 perform the same functions as in the conventional configuration, and thus description thereof will be omitted.

The billing processing unit 22 is a billing S / W, a billing collection section 22-1, a billing storage section 22-2, a billing dump section 22-3, a billing transmission section 22-4. And the MT transmission unit 22-5, the charge collecting unit 22-1 receives the detailed charging information transmitted through the IPC from the call processing unit 21, i. The billing data block is processed and stored in the billing memory section 23, and the billing section 22-2 reads the billing data block stored in the billing memory section 23 and stores it in the billing disk 24. The billing dump section 22-3 dumps a predetermined number of billing data blocks stored on the billing disk 24 to the MT 25, and the billing section 22-4 requests billing data transfer from the billing clearing house. In accordance with the present invention, the billing data block stored in the billing disk 24 is transmitted to the billing clearing house, and the MT transmitter 22-5 reads the content stored in the MT 25, that is, billing data block and transmits it to the billing clearing house. Do this.

If the charging data generated by the exchange system due to abnormal operation of the charging disk 24 is stored only in the MT 25 instead of being stored in the charging disk 24, the corresponding charging storage unit 22-2 If the start and end numbers of the billing data blocks that are not stored in the billing disk 24 are stored in the local MT information, the MT 25 reads the billing data blocks that are not saved in the billing disk 24 and the corresponding local MT information. Is initialized.

The charging processing operation of the exchange system according to the present invention configured as described above will be described in detail with reference to FIG. 3 as follows.

First, when detailed billing information for the completed call is received from the call processor 21 through the IPC to the billing processor 22 (step S31), the bill collector 22-1 of the billing processor 22 receives the received bill. After the detailed billing information is processed into data in a chargeable form, the processed billing data is primarily stored in the billing memory unit 23 serving as the main memory.

That is, the accounting collector 22-1 processes the detailed accounting information received from the call processor 21 into a billing record of a predetermined type and stores it in a local variable (step S32), and then a billing record stored in the local variable. It is determined whether or not the number of times is larger than the preset reference number, i.e., the number of charging records included in one charging data block (seven) (step S33).

If the number of billing records stored in the local variable is smaller than the reference number, the billing information receiving mode returns to step S31 to receive detailed billing information transmitted from the call processing unit 21, and is stored in the local variable. If the number of charge records is the same as the reference number, a predetermined number of charge records, that is, charge data blocks stored in the corresponding local variable are stored in the charge memory unit 23 (step S34).

Then, the charging storage unit 22-2 checks the state of the charging disk 24 as an auxiliary storage device and checks whether the charging disk 24 is abnormal, thereby checking whether the charging disk 24 is in a normal state. At step S35, when it is determined that the charging disk 24 is in a normal state, the charging storage unit 22-2 stores the charging data block in the charging disk 24, and charging the charging disk 24. By reporting to the collecting section 22 and the charging dump section 22-3, the charging dump section 22-3 dumps the charging data block stored in the charging disk 24 to the MT 25 in units of 30 blocks. However, if it is confirmed that the charging disk 24 is in an abnormal state, the charging data block is not stored in the charging disk 24 but stored only in the MT 25 (step S37). In the charging storage unit 22-2, the charging disk 24 is not stored in the charging disk 24. The start and end number of gold blocks of data are stored in a local MT information. Here, the local MT information has a structure for storing 50 tuple information, and the start and end numbers of billing data blocks not stored in the billing disk 24 are stored in each tuple. After MT 25 reads the billing data block that is not stored in billing disk 24 and stores it in the header, local MT information is initialized. After the storage is completed in the currently active MT 25, the corresponding information is checked (step S38), and in the charging S / W controlling the MT 25 before being transferred to the MT 25 in the standby state, the MT has been stored. The MT 25 is checked by winding (25) for the first time. Since the charging data block stored in the charging disk 24 and the charging data block not stored in the charging disk 24 exist together in the MT 25, any charging data block among the charging data blocks stored in the MT 25 is stored in the charging disk ( 24, it is determined whether the billing data block is not stored (step S39). For this, in the billing S / W, when a billing data block that is not stored in the billing disk 24 occurs, information about the number of the billing data block is generated. Must have

If the billing S / W determines that there is a billing data block that is not stored in the billing disk 24 among billing data blocks stored in the MT 25, the billing data block, that is, billing history is read from the MT 25 and billed. After storage in the form of a temporary file on the disk 24 (step S40), the process of the MT transmission unit 22-5 is activated.

At this time, when the charging disk 24 is restored to its normal state, the charging data block that has not been previously stored in the charging disk 24, that is, the charging data block not stored in the charging disk 24, is stored in the form of a temporary file. If the charging disk 24 has not been restored to its normal state, the charging data block is stored in a temporary file format on another charging disk 24. The MT transmitter 22-5 notifies the charging transmitter 22-4 that there is an untransmitted charge through the IPC, and the charging transmitter 22-4 performs the charging operation currently in progress. Pause for a while, and report the existence of untransmitted billing data block to the billing clearinghouse, transfer the untransmitted billing data block, i.e. billing history, to the billing clearing house according to the request of the billing clearing house. (Step S41), the MT transmission unit 22-5 is notified through the IPC that the work is completed.

After the MT transmission unit 22-5 is informed that the charging transmission for the untransmitted charging data block is completed, the MT transmission unit 22-5 deletes the untransmitted charging file in the form of a temporary file stored in the charging disk 24 (step S42). Then, it goes back to the standby state.

In addition, the embodiments according to the present invention are not limited to the above-described embodiments, and various alternatives, modifications, and changes can be made within the scope apparent to those skilled in the art.

As described above, in the present invention, if it is determined that the billing disk is in an abnormal state by checking whether the billing disk is abnormal in the exchange system, the MT reads the billing data not stored in the billing disk from the local MT information, and then the billing disk is normally recovered. By storing the billing data that is not stored in the billing disk as a temporary file in the billing disk, and if the billing disk is not recovered normally, save the billing data as a temporary file in the other billing disk and send it to the billing clearinghouse through TCP / IP. The billing data stored in the MT is transmitted to the billing settlement at low cost.
