The present invention relates to the charging method of the electronic exchange, and in particular, in the home exchange with the remote exchange as a home station, the subscribers of the auxiliary storage device register the number of registration charges until the completion of the call by performing the charging for the local call of the remote subscriber for three consecutive minutes. It relates to a method of recording in the billing area.

A typical electronic exchange, for example, the MIOCN exchange system, is configured to have a home exchange and a remote exchange in its own country.

As described above, the remote subscriber billing method of the conventional exchange system that accommodates the remote switch was a one-time billing method for one currency regardless of time, as shown in the flowchart of FIG.

FIG. 1 is a conventional billing flow chart, which comprises a subscriber billing initialization process, a subscriber billing registration process, and a counting counter recording process for registering registered subscriber billings in a subsidiary storage device of the mother exchange.

The operation of the flowchart of FIG. 1 will be described.

When the remote subscriber attempts to make a call, the home exchange exchange recognizes this and establishes a call path in the home exchange and initializes the charging information of the Cg (Calling) subscriber.

When Cg subscriber completes the Cd (Called) subscriber's station number, it analyzes CPU A or CPU B of the home exchange and examines the internal or external call of remote exchange, establishes the channel as the corresponding call, and sends ring signal to Cd subscriber.

When the Cd subscriber responds (ANSWER), the call is converted into an internal or external call, and the billing information of the Cg subscriber is converted to the counter 1 counter, and the information is stored in the auxiliary storage device of the home exchange exchange again.

However, the conventional billing method operated as described above was unable to perform billing for three consecutive minutes of local calls by making one currency one degree regardless of time.

Therefore, an object of the present invention is to add a three-minute continuous billing function for the local call of the remote subscriber to the home exchange to handle the local call time division billing service for the remote subscribers, and at the same time manage the subscriber billing information in the home exchange It provides a way to prevent the loss and loss of subscriber billing information by administering.

Another object of the present invention is to provide a local call map scanning method for scanning a remote subscriber local call bit map.

An operation example of the present invention will be described below with reference to FIGS. 2 to 8.

If the system of the mother station switch 25 of FIG. 2 is operating now, CPU A and CPU B (11) 13 will perform the job of the monitor program of the operating system (O / S) at the interval of 2 second. In accordance with the schedule, the city call map scanning procedure of FIG. 5 is executed.

In step 101, CPU A and CPU B (11) (13) executing the above-mentioned FIG. 5 check whether or not the home exchange is a remote exchange. It will return.

In step 101, in case of the home exchange with a remote switch, in step 103, whether the O / S scheduling is received is a 2 second JOB process or not, and the result is a 2 second job (JOB) process, step 109 Read from the first group number of the first remote switch in the subscriber local call map as shown in FIG.

That is, the first group number of the first remote switch local call map is taken.

If the result of step 103 is an immediate process, the process re-searches whether the process is an immediate job process in step 105, and when the immediate job process is performed, the first group number of the remote exchange local call map to be processed in step 107 is obtained.

CPU A, B (11) (13), which obtained the first group number from the local call memory map as shown in FIG. 3, checks whether there is a subscriber in the group in step 111, and if it is in FIG. Increase the 2 second counter of the corresponding subscriber by 1; otherwise, go to step 119.

In step 113, the CPU A and B (11) 13, which has increased the number of two seconds by one, checks whether the contents of the two-second counter have reached three minutes in step 115, and reaches three minutes. Increase the 3-minute counter by 1, reset the 2-second counter, and proceed to step 119. If the search result in step 115 does not reach 3 minutes, proceed to step 119 with only the 2-second counter increasing. Get the next group number of the map.

It is determined whether the group number obtained in step 119 is greater than the maximum group number in step 121, and if it is large, the process proceeds to step 123, and if it is small, the process returns to step 111 and repeats with steps 113, 115, 117 and 119.

Thus, the channel conditions of all groups of the first remote switch of FIG. 3 are scanned.

If all groups of the first remote exchange are regarded as being scanned, the number of the next remote exchange is retrieved and scanned in step 123.

If it is checked whether there is a remote exchange to be processed in step 125, in step 129, the next remote exchange number is stored in the internal memory area, and in step 131, the job processing is immediately requested and returned to the O / S monitor program. In step 127, the O / S monitor program requests and returns the 2-second interval processing program.

If the above operation is performed every 2 seconds by the O / S program, it is possible to perform 3 minutes continuous charging for all Cg (Calling) subscribers in the internal and external calls of the remote exchange.

In other words, the O / S monitor program retrieves the charging status by searching every channel status of every remote subscriber every 2 seconds.

When the remote subscriber attempts the internal or external call of the remote exchange, the operating part is composed of the Cg subscriber S1 and the CD subscriber S2 in the remote switch or the external call network in the system block diagram of FIG. After dialing the subscriber number of the CD subscriber S3, the CD (Called) subscriber number is analyzed by the CPU A (11) or the CPU B (13) of the mother exchange (25) to establish a call path to the CD subscriber. The ring current is sent to the CD subscriber.

When the CD subscriber S2 responds (ANSWER), the CPU A 11 or the CPU B 13 detects this and calls the remote subscriber local call charging information initialization process of FIG.

The CPU A 11 or CPU B 13 accessing the program of FIG. 6 checks again whether or not the Cg subscriber S1 is a subscriber belonging to the remote switch in step 133, and returns otherwise. If it is, check whether the currency is a local call.

If it is not the local call, the search result is returned. If the call is a local call, in step 137, the Cg and Cd subscribers are all checked to see if they are remote subscribers. Select one of the channels.

In step 139, the CPU A 11 that selects a call searches for whether the call is normally made in step 141. If not, the CPU A 11 initializes the remote subscriber charging information in step 143.

At this time, the initialization process of step 143 is performed as shown in the charging buffer of (A) (B) (C) (D) of FIG.

Aux phase is recorded in 4 bits of the buffer of RBCH00 in (A), and call progress IDY is stored in 11 bits.

In RBCH10 of (B), a unique number of a CG (Calling) subscriber is entered. In RBCH20 of (C), a billing grade is set to a local call grade of # 1, and a 2-second counter is reset.

The frequency counter, which is a 16-bit 3-minute counter of RBCH30 in (D), is reset to '0'.

After the initialization process is completed, the command to establish the selected internal exchange 35 or external 51 call of the remote exchange in the home exchange is sent to the Cg subscriber S1 and the CD subscriber S2 or S3 of the remote exchange, respectively.

When the mother exchange receives the response message from the remote exchange, the Cg subscriber finds the remote exchange number to which the Cg subscriber belongs and also sets the corresponding bit in the remote exchange local call map memory of FIG. Change the buffer as follows:

Call state is written to 4 bits of RBCH00 in (A) and the call progress buffer iDy is reset.

Record the CG subscriber's unique number in 16 bits of RBCH10 in (B),

(C) Set the 8-bit city charge grade of RBCH20, reset the counter to 2 seconds,

The 3-minute counter of RBCH30 in (D) is reset and changed.

When the contents of the remote subscriber charging buffer are changed as described above, the CPU A 11 or the CPU B 13 of the home exchange switch 25 makes the call progress state busy and stops the call control.

In the busy state as described above, the RBCH30 frequency count of the remote subscriber billing buffer of FIG. 4 increases by one every three minutes through repeating the operation of scanning the remote subscriber local call map at three degrees. The corresponding charge is registered in the charge buffer.

When the Cg and Cd subscribers complete the call while hooking up as described above, the CPU A (11) of the mother exchange (25) in the remote matching device (29) via the remote subscriber device (37) in the system of FIG. Send a subscriber's internal or external call recovery message.

At this time, the CPU A 11 of the mother exchange 27 receives the call processing procedure of the remote subscriber call recovery message of FIG.

The CPU A 11 of the mother exchange 27 analyzes the recovery message in step 155 to check whether the message is an internal or external call recovery message of the remote exchange, or returns a message if it is a recovery message of the remote exchange. Resets the bit corresponding to the corresponding remote internal or external channel of the remote subscriber local call map memory.

In step 157, the CPU A 11 allocates a call progress buffer to the call progress buffer allocated in step 161. The CPU A 11 allocates a call progress buffer to the call buffer assigned in step 161. The billing information is transferred and the billing registration process is activated in step 163.

Due to the billing registration process, the remote subscriber billing frequency auxiliary storage device recording process of FIG. 8 is called. In FIG. 8, in step 145, the corresponding subscriber billing frequency of the secondary storage device 100, 110 of FIG. Reads.

In step 147, the CPU A 11 obtains a three-minute consecutive billing frequency (count counter) in the call progress buffer and checks whether the billing degree of the call progress buffer is 0 at step 149. If not, return the sum of the sub storage device billing counts and the forwarding buffer billing count read in step 147 described above in step 151, and record the billing counts summed in step 153 in the auxiliary storage devices 100 and 110, respectively. Return to recover the internal or external call.

Therefore, when all the above processes are performed, the remote subscriber local call time division charging is completed.

In the present invention, although the local currency charging method is taken as an example, it should be noted that those skilled in the art may time-divided the long-distance billing method and the international billing of the remote subscribers with a slight change of the program.

As described above, the present invention provides a remote subscriber's local call memory map, a remote subscriber's billing buffer, a local call memory map scanning program, and a remote subscriber's local call charging information initialization, remote subscriber call recovery message processing, and remote subscriber billing frequency assistance. By storing time-division charges of the remote subscribers as a memory storing routine, there is an advantage that the home exchange can easily make time-division charges of the remote subscribers at the home exchange.
