BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a billing processing method for payphone subscribers in an exchanger, and more particularly, to a billing processing for payphone subscribers in a subprocessor provided in a small capacity exchanger.

The billing process for the conventional payphone subscribers was performed by the payphone itself. That is, if any subscriber enters digit information for a call using a public telephone, and an incoming call response is received, the public telephone uses the program and information loaded therein according to the condition of the currently formed call path. Charging

At this time, in order to be able to make intercity as well as international calls with the payphones, a billing program capable of satisfying the conditions of various call paths must exist in the payphones, which increases the cost of the payphones. In addition, in the case of a public telephone without a program considering the conditions of the various call paths described above, there is a problem that only a call within a limited area is possible.

Accordingly, an object of the present invention is to provide a billing processing method for performing billing processing for a payphone subscriber in a subprocessor in an exchange to solve the above problems.

The method according to the present invention is a billing processing method of an exchange having a lower processor having a matching card that can accommodate a public telephone, and a higher processor for performing overall call processing, the digit information authorized from the public telephone. A first sending step of sending a periodic pulse measurement request signal (PPM) from a higher processor to a lower processor when an incoming response is received from a corresponding subscriber; Receiving a periodic pulse measurement request signal, the sub-processor checks whether the calling line requesting the formation of a call is a public telephone subscriber line; If the calling line is a public telephone subscriber line, a second checking step of checking whether it is a first cycle after forming a call; A second sending step of sending a first predetermined number of pulses indicating the first period to the public telephone through the matching card in the case of the first period; A first timer operation step of setting and operating a timer for a time corresponding to a first period; A third sending step of sending a second predetermined number of pulses for notifying the next cycle after the timer operation is completed to the public telephone through the matching card; A second timer operation step of operating by setting a timer for a time corresponding to a next period; After performing the second timer operation step, characterized in that it comprises the step of returning to the third sending step.

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

1 is a block diagram of a small-capacity exchanger for performing the billing processing method according to the present invention. Processor (LP), an upper processor 120 which is a main processor (MP) for overall call processing in the exchange, and a receiving side subprocessor 130 (line) for matching with a receiver of a receiver not shown. Processor LP).

2 is an operation flowchart of the charging processing method according to the present invention, which is an operation flowchart performed in the calling sub-processor 110 shown in FIG.

The operation of the present embodiment according to the flowchart shown in FIG. 2 will now be described with reference to FIG. 1.

First, when a predetermined subscriber enters a telephone number of a called subscriber who wants to make a call using an arbitrary public telephone 100, the calling sub-processor 110 receives it and transmits it to the higher processor 120. The upper processor 120 performs the call processing and sends a call reception request signal to the called subscriber. The incoming call occupancy request signal is transmitted to the called party's lower processor 130 capable of matching with the called subscriber. Accordingly, the called party lower processor 130 checks whether the called party responds, and sends a call response signal to the higher processor 120 when the called party responds.

When the above-described incoming response signal is received, the upper processor 120 transmits a PPM (Periodic Pulse Metering) signal to the originating sub-processor 110. Here, the PPM signal is a signal requiring periodic pulse measurement of a call.

When the calling sub-processor 100 transmits a PPM (Periodic Pulse Metering) signal from the upper processor 120 in the idle state, the process proceeds from step 201 to step 202 of FIG. Check if it is a line. If it is not a public telephone subscriber line, it returns to idle state.

However, as a result of checking in step 202, if the corresponding line is a public telephone subscriber line, the process proceeds to step 203, and it is checked whether it is the first cycle after forming a call. As a result of the check, if it is the first cycle, the process proceeds to step 204 and transmits the number of pulses indicating the first cycle to the public telephone 100 through the subscriber matching card (not shown). The number of pulses generated at this time depends on the number set during system design, which may be one or more than one. When the number of pulses indicating the first period is transmitted, the public telephone 100 processes the set billing. That is, if the base rate is 40 won, the charge is processed for 40 won, and if it is 100 won, the charge is processed for 100 won.

In step 205, the originating sub-processor 110 operates a timer (not shown) for a time corresponding to the first period at the same time as the number of pulses indicating the first period. For example, if the time for the base rate is 30 seconds, 30 seconds is set. The time can be set differently according to the area where the public telephone subscriber requested the call.

While operating the timer, the originating subprocessor 110 proceeds to step 206 to maintain the standby state. If the operation of the timer (not shown) ends while maintaining the standby state, the operation proceeds to step 208 through step 207 to check whether the call is terminated. Here, the call termination check may be made of a hook-on state check for a public telephone and a corresponding subscriber's telephone as in the prior art.

If the call is terminated, the flow proceeds to step 209 and the calling party subprocessor 110 recovers the call path and ends the billing processing.

If the call is not ended, however, the process proceeds from step 208 to step 203 to perform billing for the next cycle. That is, since the first charging process for the call path formed through the above-described steps 204 and 205 is completed, the calling party sub-processor 110 determines that it is not the first period in step 203 and proceeds to step 210. do.

In step 210, the calling sub-processor 110 transmits the number of pulses indicating the next cycle to the public telephone 100 through the subscriber matching card (not shown). In this case, the number of pulses may also be set to one or more pulses as in the case of the first pulse number described above. The public telephone 100 receiving the number of pulses performs the billing processing corresponding to the next period.

The originating sub-processor 110 sends out the number of pulses to the payphone 100 through the subscriber matching card (not shown) and proceeds to step 211 to perform a timer operation for a time corresponding to the next period. In this case, the time may be set differently according to the region in which the call path is formed as described above. The flow proceeds to step 206 and is performed as described above.

As described above, the present invention has the effect of preventing the price increase of the payphone due to the installation of the billing processing program, by performing the billing process for the payphone in the sub-processor in the exchange, and the call path according to each region Charging for public telephones without a conditional program is also possible.
