The present invention relates to a detailed charging recording method for collecting various types of charging information such as voice calls, data calls, and packet calls and efficiently recording them in the charging recording device in the charging processing in the ISDN network.

In the conventional billing recording, detailed billing information of a call generated in an ASS (Acess Switching Subsystem) is generated by a predetermined number of lakes in the billing information generation block in the ASS, and is transmitted to the billing information collection block in the central control subsystem (CCS), and the detailed billing transmitted at this time. Since the information is one kind of detailed charging information containing only the information of the voice call, it was possible to record as one kind of charging block to the charging recorder.

However, in the ISDN network, various types of billing information, such as voice and data packets, must be stored. Therefore, a separate collection method and a billing block construction method should be introduced.

The present invention forms an integrated block capable of integrating and storing all kinds of call information in the detailed billing of storage devices having limited memory capacity, limited speed, and processing capability, and processes them irrespective of call types. The purpose of this paper is to provide a detailed billing method for efficiently handling billing information that occurs when processing a large volume of calls in an ISDN network.

In order to achieve the above object, the present invention is connected to the connection exchange bush steam responsible for the exchange by controlling the connection and control to the subscriber or relay line, connected to the connection exchange bush steam to centrally control the connection exchange bush steam and in charge of input and output processing A charge charging method in an ISDN network of an electronic switchgear comprising a central control bush steam, and a recording device connected to the central control bush steam and configured to record billing data by using a disk and a magnetic tape. A first step of classifying and collecting information by type of a call when the information is transmitted; a second step of forming the classified charging information as an integrated block for common processing and storing the information in a memory; and a third step of storing the information stored in the memory on a disk. And the fourth step of recording the information recorded on the disk on the magnetic tape. It is characterized by.

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

1 is a configuration diagram of a hardware to which the present invention is applied and shows a control structure related to detailed charging recording in an ISDN network of an exchange.

In the figure, 1 represents a connection exchange bush steam, and 2 represents a central control bush steam.

Hardware to which the present invention is applied is an Access Switching Subsystem (hereinafter referred to as an ASS) that is responsible for switching by controlling access and control to subscribers or relay lines as shown in FIG. The operator equipment connected to the CCS (2), the central control subsystem (CCS) (2), which centrally controls each ASS (1) and performs centralized processing such as I / O And various recording apparatuses connected to the CCS 2 to record and manage billing data.

The billing recorder mainly uses disks and magnetic tapes, and the disks are used for temporary storage, billing verification, and storage of various files to be sent to the final billing recorder magnetic tape.

The ASS (1) includes a block that is responsible for processing various calls and generates call information and a block for generating billing information using the generated call information, and the CCS (2) from the ASS (1) There are blocks for recording the transmitted charging information to the charging recording device and blocks for input / output.

Accordingly, the present invention efficiently collects different charging information for each type of subscriber in the ASS 1 in CC2 2 and records them in the charging recording device in the shortest time.

2 is a structural diagram of a state database for a detailed charging information recording device according to the present invention, and the detailed information of each device for recording the detailed charging information on the disks DK0, DK1, DK2, and DK3 or the magnetic tape MT0 and MT1. Indicates the state.

Each device is stored as a search key item in the database, and the state for each device is stored. The state is divided into program loading state, charging state, statistics state, blocking state, and ready state.

3 is a flowchart of a temporary memory storage process of the ISDN detailed billing information according to the present invention, and illustrates the type and collection process for temporarily storing the billing information in the CCS memory in the ISDN billing information.

When the billing information is transmitted from the call processing routine in the ASS (1) to the billing information generation routine (100), the billing information is bundled in a predetermined unit according to the type of the call and the information is transmitted to the billing collection processing block in the CCS (2). Collecting by type of call.

That is, when the general call charging information is transmitted (101), a general call common block is generated (105), and repeated from the general call charging information transmitting step 101 until the block configuration is completed (109). When the ISDN charging information is input (102), the ISDN call common block is generated (106), and repeatedly performed from the ISDN charging information transmitting step 102 until the block configuration is completed (110), and the packet charging information is transmitted. In step 103, a packet call common block is generated (107), and is repeatedly executed from the packet charging information transmitting step 103 until the block configuration is completed (111). In addition, the interlocking call charging information is transmitted (104), the interlocking call common block is generated (108), and repeatedly performed from the interlocking call charging information transmitting step 104 until the block configuration is completed.

If the number of calls collected in each memory block is different according to the type of call and collected until the charge information of one block is formed (109, 110, 111, 112), an integrated block is formed regardless of the type of call and the number of calls. Stored in the memory (113). The coalescing block operates 114 an inclusion processing routine that is in a waiting state for inclusion on the disc.

4 is a flowchart of a disk recording process of ISDN detailed charging information according to the present invention, and shows a process of recording all charging blocks in the current memory.

After the integrated block formation 113, the flag is checked whether the disk is capable of being recorded (115). The block is read (116) and recorded on the disk (117). The disk is searched for completion of the recording of all the integrated charging blocks of the memory (118), and the process of the memory search 116 and the disk recording 117 is repeated until it is completed. When all the integrated billing blocks are recorded, the capacity of the disk is examined to prevent information leakage due to the over capacity of the disk (119). If the amount is over a certain amount, the recording routine to the magnetic tape is operated (120). When the above process is performed, the disk recording operation is terminated and the recording processing routine is always in the standby state, and the above process is repeated until the recording capacity of the disk is above the limit.

5 is a flowchart of a magnetic tape recording process of ISDN detailed billing information according to the present invention, and shows a process of recording on a magnetic tape which is a final recording device.

The flag is searched if the access to the magnetic tape is easy (121). If the recording is impossible, the operation is terminated. If possible, the size can be recorded by accessing the magnetic tape and divided into the size. The charging information of the disk is read (122), and divided and recorded by the amount recorded on the magnetic tape (123).

The disk read 122 and the recording process 123 are repeated until the recording of all billing information is completed, and when the recording is completed, the contents of the disk are deleted and finished.

According to the present invention operating as described above, the processing routine is cleared by classifying the charging processing for all kinds of calls in the ISDN network only in the generation of charging information or temporarily storing the memory, and by processing the integrated block in the disk or the magnetic tape. It is possible to simplify and simplify the integrated billing processing in the ISDN network with the use of less memory, and the processing speed is improved, the efficient billing processing is effective.
