Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calling system in a private branch exchange for using a credit call service provided by a public network.

A private branch exchange (PB) accommodating a plurality of extensions
In a company or the like equipped with a private telephone network constituted by X), it is common to connect the private branch exchange to a public network so that an extension line can be transmitted from the extension line.

In such a private branch exchange which constitutes such a private telephone network, it is required to rationalize the charge to the extension originating from the outside and to simplify the operation when using the credit telephone service provided by the public network.

[0004]

2. Description of the Related Art When a call is sent from an extension housed in a private branch exchange to an external line (public network), the usage charge of the public network is provided from a common carrier (public network provider) to the private branch exchange. It is common for companies and others to make a single bill. Therefore, depending on the company or the like, there are cases where individual extension users want to share this.

For this reason, conventionally, a private branch exchange is provided with a charge management device, and information necessary for billing such as a call start time, a call time, and a called party number is sequentially collected, and a common carrier is adopted based on these. The fee is calculated according to the fee system that is used, and an invoice is issued to the user of each extension.

On the other hand, recently, a credit telephone service is provided by a common carrier. Credit calling service assigns a personal identification number to a pre-registered subscriber and dials the corresponding service special number, subscriber's subscriber number and personal identification number at the time of calling before dialing the subscriber's subscriber number. Is a service for charging the subscriber (subscriber number) for the call.

When this credit call service is used from an extension line, the conventional private branch exchange does not have a special function corresponding thereto, and all the numbers necessary for using the credit call service are provided. I had to dial.

[0008]

However, conventionally, a charge management device is specially provided in order to charge a charge for an extension line transmitted from an external line. If a failure occurs, the billing data may be destroyed, resulting in low reliability and a large number of man-hours involved in issuing a bill.

On the other hand, when calling from an extension line to an outside line, it is mandatory to use the credit call service provided by the public network, so that the charge is billed directly from the common carrier by an extension user (a subscriber registered in the public network). ), The charge management device as described above is not required, and a great rationalization can be achieved.

However, in order to use this credit call service, it is necessary to perform a large number of dial operations in addition to the subscriber number of the other party, which is a heavy burden on extension users who frequently make outside calls. , It was not possible to abolish the charge management device as described above.

The present invention has been made in view of the above circumstances, and makes it possible to use the credit call service provided by the public network from an extension accommodated in a private branch exchange with a simple operation, and to charge a fee. The purpose is to be able to abolish the dedicated equipment for the purpose.

[0012]

By inputting a service special number, a subscriber number and a personal identification number of the subscriber, the subscriber is connected to a public network which provides a credit telephone call service for charging the subscriber. The private branch exchange is configured as shown in FIG.

That is, the extension user of the private branch exchange 2 is informed to the user in advance.
The storage means 3 in which the D number is given and the subscriber number of the public network 1 for the extension user and the personal identification number for using the credit call service are registered in correspondence with the ID number.
And the ID number as an input, the subscriber number and the personal identification number corresponding to the ID number are extracted from the storage unit 3, and the special number of the credit call service, the extracted subscriber number and the personal identification number are transmitted to the public network 1. 4 and the extension terminal 5 of the private branch exchange 2 is used to make a call using the ID number.

[0014]

According to the present invention, when the extension terminal 5 dials the ID number previously given to the caller (extension user) and the subscriber number in the public network 1 of the call partner,
The sending means 4 of the private branch exchange 2 searches the storage means 3 to extract the subscriber number and personal identification number corresponding to the ID number.

Next, the service special number corresponding to the credit call service provided by the public network 1, the extracted subscriber number, the personal identification number, and the subscriber number of the calling party are sent to the public network 1.

Therefore, an extension user can dial an outside line by dialing the ID number and the subscriber number of the calling party, and can easily make an outside call using the credit calling service.

As a result, the usage charge of the public network is not added to the subscriber line connected to the private branch exchange, but is added to the registered subscriber number of the caller. Eliminates the need for processing, equipment and operation.
