BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for recording call billing content used by each subscriber in a magnetic tape in an electronic exchanger, and in particular, a subscriber station (Direct Number / Direct Number Equipment Translation Table). It is related to a method of designing the data of the station number outside the range of the detailed station number so that billing is not recorded.

1 is a control block diagram of an electronic exchange, which forms a call path between a subscriber and a subscriber by means of a predetermined control signal to make a call, and outputs a billing calculation signal by a predetermined operation (Network Peripheral Equipment) ( PPM), and centralized, common control device, two processors that share the load are operating inside, and if one processor fails, another processor can handle all the calls, and the billing data for the detailed station number by this operation. A central processor unit (CCU) for recording the data into an internal memory and outputting the same by a predetermined control, and a telegram for inputting a predetermined signal when new information is read or read into the central control unit (CCU). Typewriter (TTY) and fixing program are stored and input to central control unit (CCU) or charging data to central control unit (CCU) It is composed of a magnetic tape unit (MTU) that is output by the. In this case, the PPI includes a switching network, and each processor of the central control unit (CCU) includes a memory unit, an arithmetic unit, and a microprogram storage unit. It is divided into (Microprogram Control Store) and Program. The magnetic tape (MTU) in the configuration of FIG. 1 is for recording charging information and is also commonly referred to as a billing device.

2 is a memory table diagram of a detailed station number data design in a conventional exchange, which is a station data design memory table for designating a subscriber's telephone number in a memory in a central control unit (CCU). Reference code MA1 is the area where the home country detail station number where the actual subscriber is used is stored, and MA2 is the home country detail station number that is not accommodated by the subscriber who can make a call. The station No. is stored in the non-existing state, and MA3 is the area where the detailed station No. of the subscriber connected to the exchange is stored through the Remote Switching Unit on its own side.

3 is a flow chart of a conventional city billing, which accesses the first detail station number from the station number data design memory table, records the charging data recorded in the accessed detail station number on the magnetic tape, and then accesses the detailed station number as the last station number. Check to stop the charge recording when the last station number is found, and if it is not the last station number, access the next detailed station number and record the charge of the detailed station number on the magnetic tape.

Referring to FIGS. 1 to 3, when the charging process is described in the related art, when the subscriber SU1 is a hand cell, the peripheral device PPI is detected and output to the central control unit (CCU). At this time, the central control unit (CCU) detects the call of the subscriber (SU1) to access the address corresponding to the station number of the subscriber (SU1) in the detailed station number memory table designed as the second degree.

When the called party called by the subscriber SU1 responds in the above state, the caller peripheral device PPM detects it and outputs the charging signal (charge calculation signal) to the central control unit (CCU). Therefore, when the central control unit (CCU) says that the detailed station number memory table of the subscriber SU1 on the call by the charging signal, for example, the station number of the subscriber SU1 is " 212-4242 " The city billing data is stored in the memory table area where the detailed station number is set to "212-4242" in the table.

By the above method, the detailed station number where each subscriber SU ₁ -SU _{n +1} is accommodated, that is, the subscriber station SU1-SUn +1 of the subscriber station SU1-SUn +1 in the mother station detail station area MA1 of the memory table area of FIG. Find the table corresponding to the station number and store the city bill.

At this time, the central control unit (CCU) can actually accommodate the subscribers (DNE ₁ , DNE _{n + 1} ), but the billing details in the virtual sub-station area (MA2) of FIG. 0 "is recorded.

In addition, when there is a charge of the remote subscriber (local subscriber) connected to the remote switching unit port (RSU port), the central controller records and stores it in the local station detailed station number MA3 of the memory table of FIG.

The central control unit (CCU) commands the controller to output data for charging the billing data to the teletype writer (TTY) in order to record the subscriber's city billing information recorded in the memory table of the detailed station No. ), The central control unit (CCU) reads the first detailed station number of the detailed station number memory table areas MA1-MA3 of FIG. 2 in the process of FIG.

The charge contents recorded in the memory area of the first detailed station number read in step 1-1 are output to the magnet tape unit (MTU) under the control of the central processing unit (CCU) and stored in FIG. .

At this time, the central control unit (CCU) searches for the last detailed station number on the magnet tape unit (MYU) in 1 to 2 processes in 1-3, and stops recording the city bill when it is found to be the last detailed station number. If it is not the last detailed station number, the charge contents of the self-detailed station number memory area are read from the next detailed station number memory table area and stored in the magnetic date unit (MTU).

However, as described above, the method of recording the billing data is designed by the central control unit (CCU) by designing a virtual detailed station number even for many detailed station numbers in which real subscribers (callable subscribers) are accommodated when designing the detailed station number of the subscriber. When receiving the recording command and reading the charge contents recorded in the memory table of the detailed station No. and writing them to the magnetic tape unit (MUT), the billing content of the virtual detailed station No. with no charge contents is set as "0" because no subscriber is set. It was a problem with the record. This is because the magnetic tape, which contains the contents of the city billing for each subscriber, analyzes the details of the billing and informs the subscribers of the charges. Analysis of the billing content has caused a problem of lowering the computational analysis and processing capacity of the computer.

Therefore, an object of the present invention is to design a detailed station number that is not accommodated by the subscriber to a station number outside the range of the detailed station number so that only the billing contents of the detailed station number where the subscriber is accommodated when the city charges are recorded by each subscriber. In providing.

4 is a detailed station number data memory table according to the present invention, in which a mother station detail station number is recorded in a mother station detail station number memory area in which a subscriber is accommodated. The virtual details station number out of range is recorded, and the local station number is recorded in the memory area of the local station No. which is connected through the remote switching unit (RSU) which is the host of the exchange. Reference code MA1 is the detailed station number memory table area where the subscriber is accommodated as the mother station detailed station number area, and NOA is the virtual detail station number area of the mother station, and because the subscriber is not accommodated, the station number outside the area of the station number is stored. NA3 is the local station address memory area.

FIG. 5 is a flow chart according to the present invention in which the first detail station number is taken from the detailed station number memory table and the charging details recorded in the detailed station number memory table are recorded only when the virtual detail station number is not found.

Hereinafter, a description will be given with reference to FIGS. 1, 4, and 5 attached to the present invention. Now, when the subscriber SU1, which is connected to the subscriber port of the peripheral device PPM through the call and is registered as a subscriber of the exchange, lifts the handset as described above, the central control unit CCU detects this state. The detailed station number memory table configured as shown in FIG. 4 accesses the detailed station number corresponding to the station number of the subscriber SU1 in the mother station detailed station number memory area MA1.

When the called party called by the subscriber SU1 responds in the above state, as described above, the caller detects the signal from the peripheral device PPM and outputs the charging signal to the central control unit (CCU).

Therefore, the central control unit (CCU) records the contents of the city charge in the detailed station number of the subscriber (SU1) in the call in the MA1 area of the detailed station number memory table as shown in FIG. That is, when the station number of the subscriber SU1 is " 00-0001 ", the station number is searched in the area MA1 where the subscriber is accommodated in the detailed station number memory table of FIG. 4, and the detailed station number is set. Record it.

By the above method, the detailed station number where each subscriber SU _1- SU _{n + 1} is accommodated, that is, the subscriber station SU1-SUn + 1 of the detailed station number MA1 in the memory table area of FIG. Find the table corresponding to the station number and store the city bill.

In addition, the central control unit (CCU) records and stores in the local station number area (MA3) of the memory table of the detailed station number 4 when there is a charge of the remote subscriber (local subscriber) connected to the remote switching unit port (RSU port). In this case, NOA-1 is a detailed station number memory area in the mother country where an actual subscriber is not accommodated so that "-1", which is out of the range of the station number, is included in the detailed station number design. In order to record the contents of the subscriber's city charges recorded in the detailed station number memory table configured as the fourth figure in the magnetic tape unit (MTU), which is a charge recording device, a command for outputting data is recorded to the teletypewriter (TTY). When outputting to the central control unit (CCU), the central control unit (CCU) reads the first detailed station number of the memory table area (MA1, NOA-1, MA2) of the fourth FIG.

In this case, the central control unit (CCU) searches for the virtual detailed station number stored in the data "-1" outside the station number area in step 2-2 by the internal processor. When the billing details of the detailed station number are printed to the magnetic tape unit (MTU), the billing details are recorded as in step 2-3, and when it is determined that the virtual station number is found, the last detailed station number is searched in steps 2-4. In addition, when it is determined in step 2-4 that it is not the last detailed station number, access the next detailed station number as in step 2-5, perform step 2-2, and when it is the last station number, stop the city billing process. .

Therefore, in the magnetic tape unit (MTU) where the charges are recorded, only the charges of the mother station detail station number and the detailed country number where the actual subscriber is accepted are recorded.

As described above, the present invention designs a virtual detailed station number that does not contain a real pressure in the memory table design related to the city billing data as data out of the range of the station number, thereby generating a local billing proxy virtual detailed station number for each detailed station number. By ignoring it, it is possible to improve the processing capacity of the computer system that analyzes and processes the city billing, and at the same time, it is possible to simplify the design of the virtual station number that does not accept the subscriber when designing the exchange data.
