The present invention relates to an exchange system, and more particularly, to a method capable of recording a code having a specific service function in billing information.

In general, the exchange system does not consider special services such as 700 service call, coin box, call transfer service, etc. when recording detailed billing information. Only the essential elements (eg calling number, called number, usage time and billing start time) were recorded. Such conventional recording of detailed charging information has been performed by a flowr as shown in FIG.

Referring to FIG. 1, first, when the calling party has attempted a long distance call by lifting the receiver (step 11), the system checks in step 12 whether it is necessary to charge according to the station number analysis result. Therefore, when charging, the buffer stores all information of the originating and terminating subscribers necessary for detailed billing. At this time, the control unit of the exchange does not check whether the use of the special service registered to the calling party and the called party. In addition, in the twelfth step, if no charge is charged, no charging cell is formed. When the call of the calling subscriber is terminated in step 15, the controller records the detailed charging information on the collected billing information disk by performing step 16 when the subscriber stores the detailed charging information in the buffer of the internal module and collects it as a predetermined record. Dump it on magnetic tape (MT). After the billing information of the disk is dumped to magnetic tape. In the charge computer, the information of the tape is analyzed in step 17 to receive the information recorded on the magnetic tape and charge the subscriber. In this case, a text file is generated by being classified as a general subscriber and call 080 service call of step 19-1 according to call type (step 18). In step 19-2, a 080 service is generated. Since the call is not a charge to the calling party but a charge to the called party, the call type is marked and the other special service use call is not marked in the detailed billing information field. In the twentieth step, charges are collected to the subscribers by collecting the billing details used by the respective subscribers in the files prepared in the above steps 19-1 and 19-2.

Therefore, as described above, since the billing information is not displayed on the details of the use of the special service (except 080 service call), the billing computer database the subscriber number for each special service type and analyzes the detailed billing tape. After that, there was a cumbersome problem of charging each subscriber by using the service-specific tool. In addition, since the information based on the analysis is data transmitted from a magnetic tape or the like, there is a disadvantage in that the reliability of billing data cannot be guaranteed in case of a transmission error.

Accordingly, an object of the present invention is to display the special service used in the call type field of the detailed billing information for a call associated with a special service function when there is an incoming call in the exchange system. The present invention provides a method for efficiently performing billing information processing.

It is another object of the present invention to receive a charge for information on charges other than 700 service charges and receive 080 service calls when a text file is formed by digitizing a special service indication of detailed billing information with a key when analyzing billing information from a tape at a charge computer. The present invention provides a method of improving the reliability of billing information by comparing and analyzing the charges collected in the charge and coin box and the charges recorded in the billing data of the actual exchange.

2 is a block diagram of a system for carrying out the present invention, showing the structure of a conventional exchange system. The subscriber unit 21 is connected to a plurality of subscriber telephones (STNs) to perform an interface function between the subscribers and the switching system. In particular, the subscriber unit 21 has a charging record buffer internally, and records charging information generated from the subscribers in a corresponding charging record buffer. The order of such recordings, of course, depends on the manner according to the invention. The trunk part 22 is connected to the trunk line link and performs an interface function between the trunk side and the switching system. The MMC unit 23 is connected to the input / output devices and performs a communication function between the input / output devices and the switching system. The switch unit 24 is a module that performs an exchange function, and performs the overall switching function of the exchange system.

The auxiliary control unit 25 is connected to the switch unit 24 and processes the charging information by checking the state of the charging recording buffer of the subscriber unit 21. The system controller 26 is connected to the switch unit 24 and controls the computer and peripheral devices. The deck 28 is a device including a magnetic tape therein, and stores charging information in the magnetic tape under the control of the peripheral controller 27. The disc drive unit 29 has a disc therein and stores charging information on the disc under the control of the peripheral controller 27.

3 is a flowchart illustrating a process of displaying and processing a special service on detailed billing information according to the present invention, and the flow thereof is recorded in a detailed service information generated by a call setup. Record in a buffer, and the auxiliary control unit 25 checks the charging recording buffer and stores it in a disk when the predetermined memory size is reached. Then, the charging information stored in the disk is moved to the magnetic tape in response to an input of a storage command. By storage.

Based on the configuration of FIG. 2 described above, an embodiment of a method for displaying a special service in detailed billing information according to the present invention will be described in detail below with reference to FIG. First, in the present invention, the billing information processing is efficiently performed by distinguishing the detailed billing information by various special services in order to efficiently request the request generated by the telephone call. At this time, the subscriber unit 21 is in a waiting state for monitoring the line (STN) state of the connected subscriber telephone, and if an outgoing call is attempted from any subscriber telephone STN in this standby state, the subscriber unit 21 recognizes this in step 31. In response to the control of the auxiliary control unit 25, the subscriber unit 21 checks whether the special service of the call of step 32 is performed and records the corresponding special service in the call type field of the detailed charging information in step 33. FIG. 5 is a detailed view of the process performed in steps 32 and 33 of FIG. 3, and confirms what kind of call type the program generating billing information is in step 52. TRAFFIC TYPE is granted according to service type. In operation 54, the charge record is received from the program generating the charge information, and the charge information is stored in the BREAK DOWN indicator according to the traffic type. Referring to FIG. 3, in step 34, the calling time and detailed billing information from the subscriber in the call to starting and ending the call are temporarily stored in the billing record buffer. As is performed, the subscriber unit 21 stores the final billing information of the corresponding call in the billing record buffer. In addition, the peripheral control unit 27 stores the received charging information in a file in the disk through the disk drive unit 29 and instructs the MMC unit 23 to store the charging record stored in the disk in the deck 28. (Step 36) In step 37, the magnetic tape received from the exchange system is analyzed by the rate computer, and the call type of step 38 is largely divided into call type information of the general subscriber call service 700 service according to the type. It is divided into four types, such as charge storage, charge of 080 service call, and coin box call. This type is distinguished by digit by using special service indication of detailed billing information. Classified as Therefore, the reliability of the billing information is improved by comparing and analyzing the collected fee and the fee recorded in the billing data of the actual exchange. In step 40, a fee is charged to the subscriber by collecting the fee used for each subscriber on the billing file generated above.

FIG. 4 shows the actual memory area of the detailed billing file, and is largely divided into a talk time area, a call start time area, a power generation subscriber number, and a called party number. It can be seen that the call type indication and the backup indication attempted in the present invention within the talk time area are allocated bits internally.

As described above, according to the present invention, there is an advantage in that the billing information processing is efficiently performed by displaying a special service on the detailed billing information in the exchange system.
