After a call is completed, the exchange main body 2 stops the count of the call time, and calculates the call tariff based on the call time and the destination number of the data base 8, referring to a tariff table 6, and sums an obtained call tariff and the rent fee of the data base based on the charge information from the PB signal generator 9 of the data base 8.

Description

[Detailed Description of the Invention] U Industrial Field of Application j This invention describes a charging method for connecting an extension telephone of a private branch exchange to a database via a public network. [Prior Art] FIG. FIG. 2 is a block diagram showing a charging method of the system, and in the figure, (1) is an extension telephone, (2) is the main body of a private branch exchange in which this extension telephone (1) is accommodated, and (3
) is the central office line trunk that connects this exchange main body (2) to the central exchange, (4) is the billing device, and (5) is the billing device that connects this billing device (4) and the above exchange main body (2). The device interface (6) is a rate table connected to the exchange main body (2). (6a), (6b) and (6c) are the number area, time area, and fee area of this fee table (6), and the number area (6a)
The area code is stored in , the time area (6b) stores the call connection unit time corresponding to each area code, and the charge area (6c) stores the charge of 10 yen per connection unit time. is stored. Further, (7) is a central office switch that constitutes the public network, and the central office line from the central office line trunk (3) is accommodated in this central office switch (7).

Next, the operation will be explained. When the extension telephone (1) goes off-hook and dials a special number for making an outside call, the exchange main unit (2) connects the extension telephone (1) to the central office trunk (
3) Connect to the central office line via. Next, the extension telephone (1
) dials the other party, and when the other party answers, the exchange main body (2) starts counting the call time based on the polarity reversal information from the central office exchange (7). When the exchange main body (2) detects the end of the call, it stops counting the call time and calculates the call charge based on the counted call time and the information of the other party.

This call fee is sent to the charging device (4) via the charging device interface (5) together with the telephone number of the extension telephone (1), and the charging device (4) stores the sent information.

That is, the exchange main body (2) refers to the number area (6a) of the rate table (6) based on the area code of the destination information,
Read the call connection unit time and the charge per connection unit time from the corresponding time area (6b) and charge area (6c), and calculate the charge per connection unit time to the value obtained by dividing the call time by the call connection unit time. The call charge for the call is determined by multiplying by 10 yen. For example, if you make a 1-minute call to a subscriber in Tokyo (area code 03), you will get 6 seconds as the call connection time as a result of referring to rate table (6), so 60 ÷ 6 x 10 = 100 Accordingly, a call charge of 100 yen is calculated, which is sent to the charging device (4) and charged to the extension telephone (1). The accumulated billing information is output to a display, a printer, etc. attached to the billing device (4) as necessary.

In some cases, the billing device (4) has the function of calculating and accumulating the charges.

[Problems to be solved by the invention] Since the conventional billing system is configured as described above, the extension telephone for the terminal that accesses the database cannot calculate the call charge only from the destination number and call time. Therefore, it is not directly accommodated in the exchange body (2) of the private branch exchange,
Because it uses a phone that is directly connected to the public network,
A subscriber line contract must be made for each terminal to connect to the public network with the communication service company that owns the public network.
Furthermore, there are problems in that call charges must be managed by combining the billing output of the private branch exchange and the charges from the communication service company.

This invention was made in order to solve the above-mentioned problems, and its purpose is to provide a billing system in which a telephone for a terminal connected to a database can also be accommodated in the main body of a private branch exchange and billed. do.

[Means for Solving the Problems] The billing method according to the present invention includes providing a database with a PB signal generator, transmitting billing information from the database as a PB signal, and providing a PB signal receiver in the private branch exchange. The system receives billing information from the database in the form of a PB multiplied signal, and charges the extension telephone set for the terminal the sum of the usage fee for the database and the normal call fee.

1 Effect] The billing method in this invention is such that when a terminal extension telephone is connected to a database, the PB of the database is
The signal generator sends out the billing information as a PB signal, and
The private branch exchange that receives this with the B signal receiver charges the extension telephone set for the terminal the total charge of the usage fee for the database and the normal call fee obtained thereby.

Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1st
In the figure, (1) to (7) are the same as the conventional one denoted by the same reference numerals in FIG. 2, and therefore their explanation will be omitted.

(8) is a database stored in the central office exchange (7), (
Reference numeral 9) is a PB signal generator provided in this database (8), and this PB signal generator (9) sends out the billing information of the database (8) by a PB multiplied signal. Here, this billing information is, for example, a database usage fee. (10) is the FB signal generator (9)
This is a PB signal receiver installed in the private branch exchange to receive billing information using the PB double signal from the private branch exchange, and is connected to the exchange main body (2).

Next, the operation will be explained. Now, when accessing the database (8) from a terminal, first, the extension telephone (1) for the terminal is off-hook and the destination number of the database (8) is dialed. Upon receiving this, the main body of the private branch exchange (2) selects the central office trunk (3) and sends the destination number in the database (8) to the central office exchange (7). After that, when the polarity reversal information is returned from the central office exchange (7) in response to the database (8), it starts counting the call time and connects the PB signal receiver (10) to the selected central office line trunk (3). Connect. In this state, the PB signal generator (9) of the database (8) sends out a PB double signal indicating billing information, and the PB signal receiver (10) that receives this PB double signal transmits the billing information to the main body of the exchange (
2) Notify. When the call ends, the exchange main unit (2) detects this and stops counting the call time, and calculates the call time using the conventional method based on the call time and the destination number in the database (8) while referring to the rate table (6). The call charge is calculated in the same manner as in the above case, and the obtained call charge and the database usage charge based on the billing information from the PB signal generator (9) of the database (8) are summed. This total charge is transferred to the billing device (4) via the billing device interface (5) along with the telephone number of the extension telephone (1) for the terminal, and the billing device (4) stores this sent information. do.

That is, if the call duration is 1 minute, as a result of referring to the charge table (6), the connection unit time of the call is 6 seconds,
You can get 10 yen as a charge per unit time of connection,
If the call charge is 100 yen based on 60 + 6 x 10 = 100, and the database usage fee is given as 200 yen according to the billing information from the PB signal generator (9), the total charge is 300 yen. Yen is charged and accumulated on the extension telephone (1) for the terminal. The accumulated billing information is output to a display, a printer, etc. attached to the billing device (4) as necessary.

In the above embodiment, the charge table (6) is provided in the exchange main body (2), the charge is calculated by the switch main body (2), and the calculated charge and the telephone number of the extension telephone (1) are sent to the charge device (4). ), but the billing table may be provided in the billing device (4) and the billing device (4) may directly calculate the fee.

Further, in the above embodiment, P from the PB signal generator (9)
Although we have explained the case where the billing information based on the B-time signal indicates the database usage fee, it may also indicate the unit time of using the database and the fee per unit time. In that case, the database usage fee is , is calculated based on the billing information based on the call time counted by the exchange main body (2).

[Effects of the Invention] As described above, according to the present invention, when a terminal extension telephone is connected to a database, the PB signal generator transmits billing information as a PB double signal and receives the billing information. The private branch exchange is configured to charge the extension telephone for the terminal concerned the sum of the usage fee for the database and the normal call charge, so the telephone for the terminal accessing the database is also charged to the private branch exchange. It is now possible to directly accommodate telephones connected to the switchboard, so there is no need to use telephones that are directly connected to the public network, and call charges can be saved from telecommunication service companies by simply managing the billing output of the private branch exchange. This has the effect of eliminating the need to manage it together with fees.
