Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used in ISDN terminal equipment. In particular, the present invention relates to a technique for displaying an elapsed charge during ISDN communication.

[0002]

As is well known, an ISDN network has one D channel and two B channels. Normally, the D channel, which is a signal channel, performs line connection and notification of charges, and two information channels. Information communication between terminals is performed on the B channel. Not only for ISDN, but for general public lines, the communication charge is only revealed when the communication is completed.

[0003]

Particularly, in the communication using the ISDN network, in addition to the communication time and the communication distance, an information service use charge is also added, and a long communication cost results in a large communication charge. .. Nevertheless, since the communication fee is notified only after the communication is completed, there is often a situation in which the communication budget set before the start of communication is largely exceeded without noticing.

The present invention has been made against such a background, and an object thereof is to provide a device for periodically displaying an elapsed charge even during communication.

A second aspect of the present invention is a communication network in which the ISDN device is used, wherein the ISDN network is connected to the ISDN.
It is desirable to provide a means for sending the communication charge information to the communication device at regular intervals.

[0007]

In the ISDN network, there is a user-user signal for exchanging a small amount of information between terminals (user-user) via the D channel. The present invention focuses on this user-user signal, and utilizes this to realize the progress display of communication charges.

A circuit for extracting communication charge information from the terminal connection information during communication and a circuit for converting this communication charge information into a user / user signal at regular intervals are provided inside the ISDN network. The communication charge information converted into a signal is sent to the corresponding terminal in communication via the D channel.

In the terminal, a circuit for receiving the user / user signal is provided in the central control unit for transmitting / receiving the D channel signal, and the user / user signal is analyzed at regular intervals to extract communication charge information. To display the elapsed charge.
