The present invention relates to a method of changing a unit fee of a public telephone, and more particularly, to a method of changing a unit fee of a public telephone which changes a local, long distance and international currency unit fee of a public telephone at a long distance.

In general, in order to collect the call charge of a payphone, a unit charge is input to each of the payphones, and when a unit charge is changed, the existing unit charge must be changed to a new unit charge.

A method of changing a unit fee of a conventional public telephone will be described with reference to FIGS. 1 and 2. In the conventional public telephone 11, as shown in FIG. 1, the control circuit section 1, the coin sorting section 2, the coin storing section 3, the safe 4, the call circuit section 5, the display section 6 ), The power supply unit 7, the keypad 8, the handset 9 and the unit charge setting switch 10 is configured.

The conventional public telephone configured as described above operates as follows.

The control circuit unit 1 controls the overall operation of the public telephone, and the unit rate setting switch 10 provides the set unit rate information to the control circuit unit 1 side. The coin selector 2 determines whether the coin put is a pseudo coin and passes only the prescribed coin to the coin accumulator 3. At this time, the control circuit unit 1 displays the amount of coins determined as the prescribed coins on the display unit 6, and when coins exceeding the unit fee are received, the exchange unit and the call circuit unit 5 are connected, and the keypad 8 is used. To make it possible to dial. When dialing is completed, it is in a call state and the charging pulse from the exchange is received at regular intervals. Each time, the control circuit unit 1 receives coins corresponding to a unit charge from the coin accumulation unit 3 to the safe 4 side. Control as possible. When the call is terminated or when the call is terminated, the control circuit unit 1 terminates the call when the hand-carrying unit 9 is on-hook.

The unit rate setting switch 10 will be described in detail.

As shown in FIG. 2, the unit rate setting switch 10 includes a dip switch for setting an international call rate, a dip switch for setting a local call rate, and a dip switch for setting a long distance call rate. It consists of a dip switch (DIP3). In FIG. 2, the number represents the billed amount, and the dip switch is provided with six or eight switches SW on and off. For example, if the local currency unit rate is set to 25 won, the switch (SW2, SW3, SW6) of the dip switch (DIP2) is turned on. If the international currency unit rate is set to 1000 won, the switch of the dip switch (DIP1) is set. Just turn on (SW5, SW7).

As described above, when setting the local, long distance and international currency unit rates in the conventional public telephone 11, each unit rate should be set using the unit rate setting switch 10 provided in the public telephone. Therefore, when the unit rate is changed, a unit rate must be set by manipulating the unit rate setting switch 10 of all the public telephones, and thus, a lot of manpower and time are required, and thus there is an economically unreasonable problem.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a method for changing a unit rate of a public telephone at a distance so that the unit rate can be economically changed without requiring much manpower and time. have.

In order to achieve the above object, the present invention provides a method for changing a unit fee of a public telephone, comprising: a first process of a remote management apparatus calling a public telephone through an exchange; A second step of receiving, by the public telephone after receiving the call signal from the switch after the first step, and transmitting a reception ready signal to the remote management device via the switch; A third step of, after the second process, when the remote management apparatus receives the reception ready signal from the public telephone through the exchange, transmitting the unit fee information to the public telephone through the exchange; After the third process, the public telephone receives and stores the unit fee information, which is authorized through the exchange from the remote management device. A fourth process of terminating the operation; And a fifth process of terminating the operation when the remote management device receives the reception completion signal from the public telephone through the switch after the fourth process.

By this method, the present invention economically changes the unit rate without the need for a lot of manpower and time when changing the unit rate of the public telephone.

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

3 is a configuration diagram of a system of changing a unit fee according to the present invention. 4 is a flowchart illustrating a process of changing a unit rate of the unit rate changing system shown in FIG. 3, (A) is an operation flowchart of a remote management apparatus, and (B) is an operation flowchart of an air changer.

As shown in FIG. 3, the public telephone 20 includes a control circuit section 1, a coin sorting section 2, a coin storing section 3, a safe 4, a call circuit section 5, and a display section 6 , Power supply 7, keypad 8, handset 9, modem 12 and storage 13, public telephones 20 are connected to the exchange 14 via each other (L), The exchanger 14 is connected to the remote management device 15 via a line L '. The public telephone 20 of FIG. 3 is similar to the public telephone 11 of FIG. 1 except that the modem 12 and the storage unit 13 are added. When the remote management unit 15 changes the unit rate, the corresponding public telephone 20 to change the unit rate through the exchange 14 calls the corresponding public telephone 20 and the remote management device 15 to establish a call path. Information is transmitted to the modem 12 side of the public telephone 20 through the exchange 14. The modem 12 outputs the received information about the unit fee to the control circuit unit 1 side, and the control circuit unit 1 reads the information about the unit fee from the modem 12 and stores it in the storage unit 13. do. The storage unit 13 is configured so that stored information is not erased even when power is not input from the power source unit 7.

When the unit charge is changed, the operation is performed in the order shown in FIG. FIG. 4A is a flowchart of operation of the remote management apparatus 15, and FIG. 4B is a flowchart of operation of the public telephone 20. As shown in FIG.

First, the remote management apparatus 15 installed in the jurisdiction telephone station calls the public telephone 20 through the switch 14 (step 41). At this time, when the control circuit unit 1 of the public telephone 20 receives the call signal through the modem 12 (step 51), it prepares to receive the unit fee information and receives the ready signal for reception through the modem 12. It transmits (step 52). Thereafter, the remote management device 15 receives the reception ready signal from the public telephone 20 through the switch 14 (step 42), and transmits unit charge information to the public telephone 20 side (step 43). ). Then, the control circuit unit 1 of the public telephone 20 receives the unit rate information from the remote management apparatus 15 via the modem 12 and stores it in the storage unit 13 (step 53). Is received (step 54), the reception completion signal is transmitted to the remote management apparatus 15 side via the modem 12 (step 55), and the operation ends. Further, when the remote management device 15 receives the reception completion signal from the public telephone 20 through the switch 14 (step 44), the operation ends.

By repeatedly performing the above operation, the remote management apparatus 15 may change the unit rate information for the plurality of public telephones 20.
