Abstract

PURPOSE:To make a difference amount of a talking charge clear by printing out each talking charge onto a printer together with a command and a code corresponding to a bypass route when a line bypassed automatically is used for a line commanded from an extension terminal equipment. CONSTITUTION:External circuits 3, 6 and a switch circuit 9 are connected to plural kinds of lines 4, 7 whose talking charge system differs via extension circuits 2-1-2-m, and the kind of the lines is commanded from extension terminal equipments 1-1-1-m. In this case, a central control section 10 acquires other kind of line based on a line busy state or congestion state independently of the line of the designated kind to make bypass calling automatically. A talking charge management equipment 11 stores talking charge system data for each of plural kinds of lines and in the case of bypass calling, each talking charge by the actually commanded line is outputted to a journal printer 12 together with a code corresponding to the bypass route. Thus, the command and the bypass route and a difference from the talking charge are made clear.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone system such as a digital private branch exchange, and more particularly to a telephone system which appropriately performs a billing process when it has a so-called automatic route bypass function.

[0002]

2. Description of the Related Art In recent years, with the liberalization of the communication business, a plurality of common carriers can provide lines, and there are a plurality of types of lines having different call charge systems.

In a conventional digital private branch exchange,
It is configured such that the caller selects one of a plurality of types of lines having different call charge systems to make a call by dialing. However, even in this case, the line of the designated type may be blocked, or the route may be automatically detoured by the function of automatically selecting a line with a lower charge. In such a case, the call charge system data corresponding to the type of line actually used for the call is used for charging. But in this case
For the caller, although the caller intended to use a cheap type of line, the automatic route bypass function (for example, the caller made a call using the common carrier A, but the common carrier This means that an expensive type of line is used due to the function of automatically making a call to B.) and the call charge is charged unnecessarily high.

[0004]

On the other hand, even if a call is detoured without using the type of line instructed by the caller, the call charge for making a call using the type of line instructed There is a telephone system that performs the process of charging. In this case, there is a difference between the charge amount charged by the communication carrier and the call charge calculated by the digital private branch exchange and charged to the user. As a result, the location of the difference in charge management is unclear, and the telephone system administrator or maintenance person cannot see the history of the difference. For this reason, there arises a problem that cannot be utilized in line contract management.

The present invention has been made to solve the problems of the conventional telephone system as described above, and its purpose is to accurately know what kind of route detour was made when a route detour occurred. It is also an object of the present invention to provide a telephone system in which data based on two call charges of an instructed type line and a detoured type line can be known.

[0006]

According to the present invention, a line is connected to a plurality of types of lines having different call charge systems, and regardless of the type of line instructed by an extension terminal, other types of lines are captured and detoured when required. Calling means for making a call, call charge system data storing means for storing the call charge system data for each of the plurality of types of lines, and information for acquiring the line related to the detour call and the specified type of line Data for storing the detour route code data storing means for storing code data corresponding to the information, and each call charge system data of the line of the type instructed and the line of the detour when the detour call is made. Each call charge is calculated from the call charge system data storage means, and corresponding code data is obtained from the detour route code data storage means. Was a configured telephone system allowed a display control means for displaying the data based on the call charge in two ways.

[0007]

As a result of the above-mentioned configuration, the calculation of the call charge to the used extension terminal is always performed using the call charge system data when the call is made using the line instructed by the extension terminal, At this time, the difference between the call charge calculated using the call charge system data of the line actually used for the call can be displayed together with the code corresponding to the detour route, and what kind of route detour will be made and the difference will be You can tell at a glance what happened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a telephone system according to the present invention, showing a system using a digital private branch exchange. Extension terminals 1-1 to 1-m such as telephones are connected to extension circuits 2-1 to 2-m, and a line 4 is connected to the outside circuit 3.
Is connected to the network 5 by the first common carrier,
A network 8 of a second common carrier is connected to the outside line circuit 6 through a line 7. A call path is formed between the extension circuits 2-1 to 2-m and between the extension circuits 2-1 to 2-m and the outside line circuits 3 and 6 through the switch circuit 9 under the control of the central control unit 10. .. Central control unit 10 has a call charge management device
11, a journal printer 12 is connected to the call charge management device 11.

FIG. 2 shows detailed blocks of the central control unit 10, the call charge management device 11, and the journal printer 12 in the above system. The central control unit 10 is provided with a CPU 21, a main memory 22 in which programs and data used by the CPU 21 are stored, a timer 23, an interface 24 with each circuit, and an interface 25 with the call charge management device 11. On the other hand, the call charge management device 11 makes a call via the charge system data and the second common carrier network 8 when the call is made through the calculation means 31 including a CPU and the first common carrier network 5. Storage means 32 that stores the detour pattern code table that determines the code based on the combination of the charge system data in the case of dialing and the route of the dial input by the extension terminal and the route of the dial converted by the automatic route bypass function. Has been. An example of the structure of this detour pattern code table is shown in FIG.
This table has a structure in which a route detour pattern code is uniquely determined by a combination of dial data input by a transmission extension and converted dial data when detoured. Here, if the route is not bypassed, this code is not determined. The journal printer 12 is a display unit 41 that performs display output.

Further, as shown in FIG. 3, the main memory 22 in which data used by the CPU 21 and the like are stored is provided with a route detour table 22A for performing an automatic route detour, for changing a dial number. The data is stored. In this embodiment, the CPU 21 executes the automatic route bypass when the outside line circuit corresponding to the dial number input by the caller is busy. A part of the main memory 22 is a charging dial table 22B and a sending dial table 22C, and dial data input from the extension terminal 1 is stored in the charging dial table 22B.
Further, the dial data used for making the call is stored in the sending dial table 22C.

In the digital private branch exchange system configured as described above, the main memory 22 stores the program of the flowchart shown in FIG.
21 performs call processing and billing processing by the program. Here, the operation will be described assuming that the dial input ABC for making a call to the partner telephone 13 is made from the extension terminal 1-1 through the line 7 as shown in FIG.

The system 21 is started by starting up the system, and the CPU 21 takes in the dial by the dial input through the extension circuit 2-1 and the interface 24 (401).
. Therefore, the CPU 21 accesses the corresponding outside line circuit 6 based on the dial data ABC, and determines whether or not to bypass the route depending on whether it is in a busy state or a congestion state (402). Here, when performing route detour, the transmission dial is set to D, for example, based on the route detour table 22A.
Convert to EF (403). Next, the dial ABC input by the extension terminal 1-1 is made to correspond to the billing dial table 22B in the main memory 22, and the dial DEF converted by the automatic route detour is made to correspond to the sending dial table 22C in the main memory 22, respectively. Store (404). Next, the necessary dial signal (DEF here) is transmitted (40
5) The call channel is formed by the response from the partner telephone 13 (406). At the same time, the timer 23 is started, and the end of call is detected. When the end of call is detected (407), the process proceeds to the charging process based on the dial tables in the charging dial table 22B and the sending dial table 22C (408).

Specifically, the CPU 21 obtains from the interface 24 the identification information (ID, extension number, etc.) of the extension terminal 1-1 that has made a call, and uses the dial data ABC of the charging dial table 22B and the sending dial table 22C. Corresponding to the DEF 2 data, the timer 23 is stopped at the end of the call, and the identification information of the extension terminal 1-1 and the input dial data A
The BC, the sending dial data DEF, and the call time (start / end time) are sent to the calculating means 31 via the interface 25. The calculating means 31 extracts the charge system data of the line of the first common carrier network 8 based on the billing dial data ABC, detects the discount of the call time zone, the distance data, the unit time charge data, etc., and talks with them. The call charge is calculated from the above, and the call charge to the extension terminal 1-1 is charged. Further, the charge system data of the line of the second common carrier network 5 is taken out based on the outgoing dial data DEF, and the call charge is calculated in the same manner, and the difference from the call charge charged to the transmission extension terminal 1-1 is calculated. Next, the detour pattern table stored in the storage means 32 is referenced with the dial ABC input by the originating extension terminal 1-1 and the dial DEF converted by the automatic route detour. In the example of the detour pattern table in FIG. 4, the pattern code # 1 is obtained. This code is used as a billing destination, and the difference is billed. The journal printer 12, which is the display means 41, has format data for outputting both calculation results given from the calculation means 31 side by side, for example, in the vertical direction, and based on this format data, for example, a call charge list is output and displayed as shown in FIG. In the example of FIG. 5, the extension I is added to the first and second lines.
From the extension terminal with D (identification information) "3000", the dialing with the destination number "XXXXXX" is performed, and the call charge is "500 yen", but the route pattern code " It indicates that the call was made using the route of "# 1" and the difference "200 yen" occurred. The detour pattern code allows the maintenance staff to know what detour occurred from a table, for example.

According to this, it becomes clear what kind of detour caused the difference between the billing amount to the originating extension terminal caused by the automatic route detour and the actual cost,
It can be useful for accounting. In addition, if statistics are collected for each detour pattern code, the detour frequency can be grasped, which will be helpful for the line contract plan. If the route is not detoured, the detour pattern code is not determined and the difference is not generated, so it is not displayed in the call charge list.

In this embodiment, when the pattern code is used as the billing destination, the difference is simply displayed, but whether the difference is increased or decreased as compared with the case of using the line of the type indicated is a minus plus or a triangle. It is also possible to add and display the upward and downward marks. Further, in addition to the above, it is also possible to display not the difference but the actual call charge.

[0017]

As described above, according to the present invention, data based on the call charge when using the designated type of line and the call charge when using the type of line related to detour corresponds to the detour route. Since it is displayed together with the code of, it is possible to know the information necessary for management such as what kind of detour is made and how much the difference is. Therefore, it is convenient that the frequency of detours can be grasped to be useful for the addition of lines and the accounting uncertainties can be eliminated.
