The present invention relates to a fare processing method for a long distance long distance public telephone of a remote switching device, and more particularly, to a specific time fare discount method that can reduce the fare for long distance long distance public telephone users at night or at a specific time when the call volume is small.

In general, the rate discount was discounted by 20% from the normal rate to the user from 22 am to 6 pm, when the call volume was relatively low in D.D.D.

On the other hand, the public telephone (D.D.D) has been performed by the conventional charge processing program (a) and apparatus (b) of FIG.

The method of FIG. 1 is described in detail. When the call is carried out, a handset of a long-distance long distance public telephone (DCB: DDD Coin Box) is picked up and a fee is charged. The remote switching unit (1) control unit (CU: Control Unit) calls By detecting the call point (call state) of the party, the local exchange 2 is informed, and the local exchange 2 sends predetermined information to the remote exchange apparatus 1.

At this time, the control unit (CU) of the remote switching device (1) examines bits 0-3 of the fifth byte of the received information and selects a charge cycle according to the region corresponding to the code to make a temporary buffer. After saving the fare cycle in the next 100ms, decrease the fare cycle by 1 every 100ms, and when it is "0", it sends out a signal that drops the coin of the long distance long distance public telephone (DCB) and continues until there is a fare (coin). I've been done to end the call.

Here, the SMU acts as a switching between the long distance public switched telephones and the local exchanges, while the LGI (Line Group Interface) and LSCL (Line Self Control Logic) only carry information. In addition, LC (Line Card) converts public telephone caller's voice signal (Analog) signal into digital signal, and SPP / SUB (Semi-Postpay Subsoriber Public Telephone Circuit Unit) connects public telephone to LC and B signal from CU. Provide B signal to long distance public telephone according to control information.

As a result, there was no way to charge a fare in the D.D.D. As a result, there was a problem that call management could not be made effectively because public telephone calls were made like regular calls during a time when a lot of calls were made, and there was a drawback that the users of public long distance telephones could not benefit.

In addition, the specific time rate discount method currently used is a method of directly discounting the subscribers at the national bridge bridge, which has a problem that the remote subscriber cannot receive this function.

Accordingly, it is an object of the present invention to provide a method capable of paying a charge in an out-of-pocket automatic telephone (D.D.D) at a characteristic time when the call volume is relatively small (during a limited time).

It is another object of the present invention to provide a method for improving the efficiency of call management since it is possible to derive the usage time of the automatic telephone user in public time to avoid the busy time (busy time) to the less busy time (limited time). Is in.

It is another object of the present invention to provide a method for transmitting more information to a remote switch, so that the remote switch can perform the same, thereby providing more services to the subscriber.

Therefore, in order to carry out the object of the present invention, the first step of checking the normal time and the discount time according to the public telephone use information of the local exchange according to the state of use of the public telephone of the remote switching device, and according to the normal and the discount from the process. The second process of selecting a data table according to the classification and rate reduction rate, selecting a charge period according to the call distance setting area, and moving it to the processing area, and storing the storage count value of the second process according to the rate discount rate and the setting area. And a third process of down counting to determine the use talk time.

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

FIG. 2 corresponds to a control unit CU of the remote switch 1 of FIG. 1 for carrying out the present invention.

In the second stage, CUP is a central controller, ROM is a read only memory, RAM is a random acces memory, and I / O is an input / output port.

FIG. 3 is a flowchart according to the present invention. FIG. 4A is a diagram of FIG. 4A is information sent from the local exchanger 2 to the remote switching unit 1 as a control unit CU, and FIG. In the 5th byte of a), it is the mode to check the normality and charge.

Therefore, the present invention will be described in detail with reference to the above-described drawings. When the caller picks up the handset and enters a coin in a long distance public telephone (DCB), the control unit (CU) of the remote switch exchanges the caller's time of call. It detects (call state) and informs the local exchange (2). At this time, the specific time rate discount program built in the local exchange 2 sends information to the control unit (CU) of the remote switching apparatus 1 by searching whether the current time is a time discounted rate every two seconds. Here, FIG. 4A in FIG. 4 is information transmitted from the local exchange 2 to the control unit CU of the remote switching apparatus 1, and the first byte (B) informs the information at which the message starts. The byte (B) indicates the type of information (long distance public long distance), the third byte (C) is the call selection information (between the public telephone and the local exchange), and the fourth, fifth and sixth bytes (B, B, B). ) Is a spare byte, and the seventh byte is a check sum. Select the predetermined byte, namely the fifth byte (e) of the above-mentioned spare byte (la-bar), and set the mode for discount of the charge. Periodic table, the discount period table is selected when "1 0", and the call zone is divided according to the distance of caller and receiver at 0-3 bits of the next 5th byte (e). Give it a different period so that it can be selected and the error of received information can be detected in the 7th byte.

Therefore, the central control unit (CPU) of the control unit (CU) of the remote switching unit has the data inputted through the data bus as shown in FIG. 4A of FIG. 4 inputted by a program embedded in the ROM. Search bits 6 and 7 in the fifth byte (e), and if it is "0,0" in the process of (c) of FIG. 3, it is normal according to the designated symbol in the normal counter table stored in the ROM as shown in Table 1 below. Select a fee schedule.

TABLE 1

Therefore, the contracted tariff schedule is selected in accordance with the division set by the telephone station of Table 1 above, and the 1-5th tariff period selected from 0-3 bits of the 5th byte according to the calling zone (Fig. 4, 4-b). In Fig. 6, a predetermined charge period is selected to store a predetermined count value in a predetermined area (temporary buffer) of RAM. At this time, after 300ms from the initial call point, the control unit resets the B signal to the unit (SPP / SUB) by a public telephone.

Every 100ms, the counter value of the temporary buffer periodically stored is counted down according to the contract rate by 1, and the identification is dropped on the long distance long distance public telephone (DCB) when the rate cycle becomes "0". You can continue to talk until you have a coin. If there is no coin to drop, the call is blocked and the long distance public phone cannot make a call.

On the other hand, as shown in FIG. 4, if bits 6 and 7 are retrieved from the fifth byte (e) of the information and "1,0" in the process of FIG. 3 (c), the discount counter stored in the ROM as shown in Table 2 below. Select a discount rate schedule from the table.

TABLE 2

Therefore, if the discount rate is set in accordance with the division set by the telephone company of Table 2 above, and discounts are made in international calls, select the discount rate, the contract data such as the corresponding country, the side discount rate period table, and the call zone in the fifth byte 0-3 bits. A predetermined charge cycle is selected from the selected 1-5th charge cycles, and the predetermined count value is stored in a predetermined area (temporary buffer) of the RAM. After 300ms at the beginning of the initial call, after every 100ms, the fixed count box is set to 1 by the discount rate. When the value reaches 0, a signal is sent to the long distance long distance public telephone (DCB) to continue to make calls until there is a coin. Since a predetermined discount rate is added to the above-mentioned normal time, the coin dropping rate is slowed and a talk time may be longer for a specific time. And if there is no coin to drop, the currency is blocked and ends.

As described above, the rate can be discounted for a specific time of the long distance public telephone according to the data table set in the discount rate periodic table.

As a result, it is possible to derive from the time when the call is busy to the time when there is no call at night, so that the call management is easy and the actual rate discount is made in the remote switching device, thereby increasing the utilization rate of the remote device and providing the user with a multifunctional service. There is an advantage to this.
