Abstract

PROBLEM TO BE SOLVED: To make a call with an interruption telephone set during communication by interrupting communication with a database at the time of detecting a ring-back tone during a call and also changing-over the telephone set of a terminal equipment to be communication possible. SOLUTION: A display device 36 which receives a signal from a control part 35 displays the sign of under catchphone reception. In an AND circuit 38, the signal is inputted when the ring-back tone is detected from a ringback tone detecting circuit 34 and the control part 35. Only when the signals are inputted from both, the signal is transmitted towards a changeover switch 30 so as to change-over the switch 30 which is connected to a network controller 31 side to a telephone 4 side. Thus, at the time of a catchphone by a the telephone set 5 during communication with the database 1, the switch 30 is immediately actuated. Then, an exchange 2 is connected to the telephone set 4 so that the call can be made with the interrupting telephone set 5 by oscillating an on-hook tone from the telephone set 11.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a database,
The present invention relates to a home-use communication amusement system including a large number of terminals which receive desired information from a database through a public communication line.

[0002]

2. Description of the Related Art In a home communication amusement system in which required information is distributed from a database to a terminal through a public communication line, when a telephone of the terminal has a call waiting function, a call waiting function is provided during communication between the database and the terminal. When you enter, a message such as "Communication error" is displayed on the screen of the terminal so that you can know that the call waiting has been activated.

However, in such a conventional system, the telephone cannot be used until the communication with the database is completed, and the communication with the database cannot be cut off and the call waiting cannot be switched to talk. There was a problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to make a call to a telephone that has interrupted by switching to call waiting even during communication with a database. It is to provide a communication amusement system for business.

[0005]

The above object consists of at least one database in which a large amount of amusement information is recorded, and a large number of terminals capable of receiving desired amusement information distribution from the database through a public communication line. In the communication amusement system, when the terminal phone has a call waiting function and a ringback tone is detected during communication with the database,
This is achieved by the above-mentioned home-use communication amusement system, characterized in that a switch for disconnecting the communication with the database and switching the telephone of the terminal device to a callable state is provided. Thus, this changeover switch can be changed over automatically or manually.

[0006]

With the above-mentioned structure, it is possible to talk with the telephone that has been interrupted during the communication with the database.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing the configuration of a home communication amusement system according to the present invention. In the figure, 1 is a database, 2 is an exchange that controls a communication network, 3 is a terminal, 4 is a telephone connected to the terminal 3, and 5 is a telephone that is interrupted by a call waiting call.

The database 1 is connected to the terminal 3 via the exchange 2, and the exchange 2 and the terminal 3 are connected by a telephone line 20. The telephone 4 can be connected to the exchange 2 via the terminal 3. Phone 5
It is connected to the exchange 2.

The main part of the terminal 3 is a changeover switch 3
0, the network control device 31, the performance section 32, the main speaker 33, and the ringback tone detection circuit 3
4, a control unit 35, a display device 36, a sub-speaker 37, and an AND circuit 38.

The network control device 31 is connected to the telephone line 20 so as to receive a communication signal from the exchange 2 via the changeover switch 30. Changeover switch 30
Is the network controller 31 or the telephone 4 and the exchange 2
When the database 1 is being communicated with, it is connected to the network control device 31 side, and the connection is sent to the telephone 4 side by a signal sent from an AND circuit 38 described later. It is to switch.

The main speaker 33 is connected to the network control unit 31 via the performance unit 32. The signal sent from the network control unit 31 is amplified by the performance unit 32 and converted into voice by the main speaker 33. To be done.

The ringback tone detection circuit 34 is connected to the telephone line 20 so as to directly receive the communication signal, and when the ringback tone is detected in the communication signal, the control section 3 is provided.
The detection signal is sent to 5.

The control unit 35 is connected to the ring back tone detection circuit 34, and when receiving the ring back tone detection signal, the display unit 36, the sub-speaker 37 and the A speaker.
An appropriate signal is sent to the ND circuit 38. The display device 36 that has received the signal from the control unit 35 displays the sign indicating that the call waiting call is being received, and the sub-speaker 37 emits an electronic sound to notify that.

The AND circuit 38 receives a signal when the ringback tone is detected from the ringback tone detection circuit 34 and the control section 35, and is input to the network control device 31 side only when both signals are input. A signal is sent to the changeover switch 30 so as to change the connected changeover switch 30 to the telephone 4 side.

In this domestic communication amusement system, the changeover switch 30 is actuated as soon as the call waiting is turned on by the telephone 5 during the communication with the database 1, so that the exchange 2 and the telephone 4 are connected. By transmitting an on-hook tone signal from the telephone 4, it is possible to communicate with the interrupted telephone 5.

The present invention is not limited to the above embodiment. For example, in the above description, when the ring back tone is detected, the changeover switch is actuated dynamically, but this can also be done manually.
Further, it is recommended to provide a system for terminating the transmission of data to the database when these changeover switches are activated, and the present invention can be easily performed by those skilled in the art from the above description. It covers all conceivable modifications.

[0017]

Since the domestic communication amusement system according to the present invention is configured as described above, according to the present invention, when the call waiting call is interrupted during the communication with the database, the communication with the database is terminated. You can talk to the call waiting person.
