Abstract

PROBLEM TO BE SOLVED: To properly execute charging processing without generating the omission of charging with respect to an international speech by charging based on charge data corresponding to a prescribed charge section in a case when charging section information can not be detected. SOLUTION: A central control part 2 fetches the identification number of a calling telephone set such as 11-1 and the dial number of an opposite party to store in a memory 4. Then, this system executes charging processing through the use of data in a charge section of the highest price in a case when a nation number coincident with a nation number extracted from the telephone number of the opposite party does not exist in a nation number table in the case of an international speech. Namely, charging processing is executed by the section of the highest price in the charge section table and its result is coordinated with the identification number of the telephone set 11-1 and outputted from an input/output device 7 through an input/output interface 6. As charging processing like this is executed, it is possible to charge without shortage in spite of calling to a nation which does not enter to the nation number table.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An electronic exchange system according to an embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows the configuration of the electronic exchange system. The electronic exchange 1 includes telephone interfaces 9-1 to 9-m connected to telephones 11-1 to 11-m and office lines 12-1 to 1-m.
2-n connected to the line interface 10-1 to 10
-N.

The above-mentioned telephone interface 9-1 to 9-m
A communication path between the telephone line interfaces 10-1 to 10-n or the telephone interfaces 9-1 to 9-m is formed by the exchange switch 8. The electronic exchange 1 further includes a central control unit 2, a memory 4 connected to the central control unit 2 via a bus 3, a charging database 5,
An input / output interface 6 is provided.

The central control unit 2 controls each unit for the exchange process using the program and data in the memory 4, and performs the charging process using the data of the charging database 5. Further, an input / output device 7 is connected to the input / output interface 6, and the input / output device 7 is used when outputting a result of a billing process and the like.

The accounting database 5 is provided with a country code table (country code storage means) as shown in FIG. The country code table stores a charge category and a destination (country or region name) corresponding to the country code. Here, the country codes are arranged in ascending order in the country code table.

In addition, the charging database 5 contains
(Charge classification storage means) as shown in FIG. In the charge section table, day charges, night and holiday charges, and late night and early morning charges are stored for each charge section. The daytime charge, nighttime and holiday charges, late night and early morning charges are each composed of a charge up to the first 60 s (second) and a charge (unit: yen) every 6 s after 60 s. I have.

The memory 4 has a program corresponding to the flowchart shown in FIG. 4 for collecting data for performing billing processing, and a billing process shown in FIG. Are stored. Hereinafter, the operation will be described based on these flowcharts.

The central control unit 2 has a telephone interface 9
It monitors the telephones 11-1 to 11-m for outgoing calls via -1 to 9-m (S1). Here, when the outgoing call is detected, the outgoing telephones 11-1 to 11-1
The ID number of -m and the destination dial number are fetched and stored in the memory 4 (S2). Then, a dial signal is transmitted through the office line interfaces 10-1 to 10-n,
Wait for the other party's response. Station line 12-1 when the other party answers
12-n is the line interface 10
-1 to 10-n are detected and notified to the central control unit 2. In response to this, the central control unit 2 detects the start of a call (S3). If the hook is made before the start of the call (S4), the process returns and the process is performed from the beginning.

For example, when the telephone 11-1 makes a call and detects a polarity reversal by a call made using the central office interface 10-1, the central control unit 2 controls the exchange switch 8 to control the telephone 11- 1 and office line interface 10
-1 is formed, and a talk time timer corresponding to the telephone set 11-1 is started (S5). Then, the central control unit 2 detects the end (on-hook) of the telephone set 11-1 via the telephone interface 9-1 (S100).
6) When the end of the call is detected, the call time and the time obtained by the timer are made to correspond to the identification number of the calling telephone set 11-1 and the destination dial number stored in step 2 and the charging queue ( queue) and stops the talk time timer (S7).

Next, the central control unit 2 detects whether or not a billing process has been performed (S8). If it is not a billing process, the process returns to step S1 to continue the process. Then, a process target is taken out from the system (S9), and whether or not a domestic call is made is detected based on the destination dial number (S10).
Here, if it is detected that the call is a domestic call, a billing process for the domestic call is performed. On the other hand, if the call is not a domestic call from the other party's dial number, the process proceeds to a call process for an international call shown in FIG.

In the call processing for an international call, a country code is read from the head of the country code table shown in FIG. 2, for example (S11), and a country code part (head part) is extracted from this and the destination telephone number stored above. (S12 (country code detecting means)). If the comparison results in a mismatch, it is detected whether there is a next candidate for the country code in the country code table (S1).
3) If there is a next candidate, the process returns to step S11 to continue the process. While the comparison is continued in this way, if the country codes match, the charge category corresponding to the matched country code is determined (S14), and based on this charge category and the current time, FIG.
The accounting process is performed using the data of the fee classification table shown in (1) (S15 (first accounting unit)). For example, if the country code is “852”, the charge category “B” is obtained from the country code table. For example, if the call time is in the daytime, 34 yen is calculated from the charge classification table to 60 seconds, and 19 yen is calculated every 6 seconds thereafter. For example, the talk time is 90
In the case of seconds, the sum of 34 yen in the first 60 seconds and 190 yen (60 超過 6 × 19) for the excess of 60 seconds is added to 224 yen, and this result is associated with the identification number of the telephone set 11-1. Output from the input / output device 7 via the input / output interface 6 (for example, printed out).

On the other hand, if there is no country code in the country code table corresponding to the country code extracted from the destination telephone number in spite of the search of the country code table, the process proceeds from step S13 to step S16. Then, a charging process using the data of the highest price category is performed (second charging means). For example, in the charge category table of FIG. 3, when the charge category C is the highest, charging processing is performed according to the category, and the result is associated with the identification number of the telephone set 11-1 via the input / output interface 6. Input / output 7
(For example, printed out). Since such a billing process is performed, even if a call is made to a country that is not entered in the country code table, it is possible to make a bill without a shortage of charge, which is suitable as a facility such as a hotel where the electronic exchange system is introduced. It is.

In the above example, the call time was not taken into account, but the highest price category C was used in the daytime, the highest price category A was used at night and on holidays, and the highest May be used. In addition, it is not always necessary to use the highest price category, and the cheapest price category or a price category close to the average can be used. That is, despite the search of the country code table, the charge classification in the case where the country code corresponding to the country code extracted from the destination telephone number does not exist in the country code table is stored. This storage can be changed by a predetermined input from one of the telephones 11-1 to 11-m, for example.

Further, in the above description, a linear search performed sequentially from the head side is employed as a search of the country code table, but a binary search may be employed. A binary search is a comparison of the middle item of a list in ascending order, and if the key item is larger than that, it compares it with the center item of the second half of the list.If the key item is smaller, the first half of the list is compared. This is a method of searching for a target key item by repeating a process of comparing with a central item.

[0023]

As described above, according to the present invention, when the charge category information cannot be detected, the charge is performed based on the charge data corresponding to the predetermined charge category, so that the call charge is always made according to the desired charge category. Request can be made.

As described above, according to the present invention, billing is performed based on the fee data corresponding to the highest price category, so that even if a call is made to a country to which no entry has been made, billing is performed without shortage. This is suitable as a facility such as a hotel where the electronic exchange system is introduced.
