Abstract

The method minimizes the loss of charged fee data by utilizing various sub-storage devices even when one of the storage devices is in fault and offers the flexibility of selecting the recording format according to the user's choice. The method comprises the stages of: the 1st stage (201-204) for compounding charged-fee data into one block of data; the 2nd stage (205-207) for recording the one block of the data into a disk and reading/writing it to a magnetic tape (MT); and the 3rd stage for recording the block data into a cue when all disks are faulty.

The present invention relates to a detailed charging recording method of the electronic exchanger.

Most small and medium capacity exchange systems use a simple method of recording charging data on the MT (Magnetic Tape) when the billing data is generated for the call used by the subscriber. In order to improve the reliability of the function, a detailed charging recording method using various auxiliary memory devices is used.

The present invention proposes a charging method for minimizing the loss of billing data even when a failure occurs in the billing data receiver specific auxiliary storage device by effectively using various auxiliary storage devices mounted in the electronic exchanger, and also improves the performance of the large-capacity exchanger. The purpose is to provide a detailed billing method that meets the requirements of the system operator and provides flexibility (Flexubukuty) for selecting the billing method.

In order to achieve the above object, the present invention manages access to and control of subscribers or relay lines, and performs an exchange such as a connection exchange system, a central system connected to the system, and a disk and an MT connected to the system. In the detailed billing device having a storage device, if billing data is generated for a call used by a subscriber, a first number of billing data is formed by combining a predetermined number of the billing data and requesting the storage in the auxiliary memory device. After the first block of charge data is stored in the disk unit of the normal state, the second step of reading the charge block stored in the disk later and stored in the MT (MT), and if the disk mounted in the system after the second step is all abnormal First, characterized in that consisting of three steps to record the charging data in the queue.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a control structure diagram of a system related to a process of generating billing data for charging a call used by an exchange subscriber and storing it in an auxiliary memory device, and is responsible for switching and controlling access to and control of a subscriber or a relay line. Access Switching Substem (hereinafter referred to as ASS (Access Switching Subsytem) (1)) and Central Bush Steam (hereinafter referred to as Central Control Subsystem (CCS) (Central Control Subsystem)) 2) It is composed of various auxiliary memory devices connected to CCS and storing charging data, and input / output devices in charge of input / output.

As an embodiment of the present invention, the auxiliary memory device is equipped with four disks (two DK1 and two DK0) and three MT (MT0, MT1, MT2) devices, and DK1 is used as a dedicated data recording device, and DK0. Is used to store various executable programs and databases to be installed in ASS and CCS. If a failure occurs in both DK1, DK0 can also be used to record charging data. In addition, to increase the reliability of the charging data, DK0 and DK1 are always operated in pairs. In other words, in terms of charging function, if the charging data is recorded in DK1, the contents are duplicated in other DK1.If the charging function is recorded in DK1 in the charging function when DK1 is abnormal and other DK1 is in normal state, the contents are different. If it is stored in DK1 and later DK1 is reduced to a normal state, the contents of other DK1 are duplicated in DK1.

In addition, three MTs are mounted in the system, in which any two MTs are set for charging, one of the two is preferentially used for charging, and the other MT is charged immediately upon failure of the other MT. It operates in a standby state in the system to store data.

FIG. 2 is a flowchart showing detailed billing. Billing data transmitted from ASS to CCS is 201 sequentially stored in a queue (202), and a certain number (50 in the present embodiment is 1 block). (203), the storage is requested to the auxiliary memory device (204). When a charge request for one block of charging data is received (205), the state of the disk is checked (206). If the disk exists in a normal state, the charging data is stored on the disk (207). Save (208).

FIG. 3 is a flow chart that records charging data in the secondary memory device when a disk in a normal state exists. If DK1 is normal, it is stored in DK1. If DK1 is abnormal and DK0 is normal, it is stored in DK0 (301). In this case, the number of billing data stored on the disk is checked up to the present time (302). If the disk reaches the capacity limit, the system operator is notified of this, and all billing data stored on the disk can be read (303). (304)

However, in the present embodiment, a function is provided so that the charging method of the charging data can be operated in two ways, one of which includes the charging data on a disk and if the number is over a certain number (28 blocks in the present embodiment), the charging data is recorded until then. Is read from the disk and stored in the MT operating in billing mode. This method has a disadvantage in that the system operator frequently needs to replace the MT containing the billing data in the case of a large exchange. In order to compensate for the drawbacks of the former method, the other method continuously records charging data on the disk to the limit of the capacity of the disk and reads all charging data recorded on the disk up to the MT until the request of the operator later. Way. Therefore, if the number of billing data recorded on the disk is 28 blocks and reads it on the MT, if the number of billing data on the disk is 28 blocks (306) It checks whether the MT of the mode exists (307) and reads 28 blocks of charging data from the disk (308) and stores it in the corresponding MT (309).

4 shows a process of storing charging data in a queue. When a charging disk is stored in a queue because a disk in a normal state does not exist, the number of blocks of charging data contained in the queue is a certain number (28 in this embodiment). If it is abnormal (401), if the charging mode MT exists (402), the contents of the queue are read (403) and stored in the MT (404). If the charging mode MT does not exist and the queue reaches the threshold (405), The contents are read (406) and output to the output device (407).

The present invention configured as described above can provide more accurate charges to the subscriber by improving the charging reliability of the electronic switch, and also provides a detailed charging method that can satisfy the performance of the large-capacity electronic switch.

In addition, by using the same billing recording method for the electronic information exchange development of the integrated information communication network, accurate charges can be imposed on various services provided to subscribers connected to the integrated information communication network.
