Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of a system for implementing the present invention, as shown in the figure, is installed in the telephone 110, and after pressing a specific switch is pressed a telephone number of the other party in the telephone 110 public telephone network 130 Push-button dialer 120 for calling the service provider to transmit the phone number of the other party through the call, and receiving the outgoing signal of the push-button dialer 120 to the phone number of the other side phone 140 to the public telephone network 130 Call) and transmits an advertising message from the call service providing system 160 to subscribers and receivers of the phone 110 and 140 for a predetermined time when a call is established in response to the phone 140. It is configured to include a digital exchange system 150 to provide a post-call service.

The digital switching system 150 is configured to include a wired incoming call function, an automatic relay function, a free phone additional equipment connection function, a three-way call function, an advertisement listening time zone and a call / ban caller function.

The call service providing system 160 includes an automatic guide function, an input and correction function, a statistical function, a data transmission function, and a time zone setting function for each time zone.

The push button dialer 120 is configured to input and transmit 32 digits of data.

Reference numeral '170' in the drawing is a central control system configured to include an advertisement recording / listening function, an intelligent network processing function, a data transmission function, a remote maintenance function, and the like.

An exemplary view showing a signal transmission process of FIG. 2 and an operation flowchart of FIG. 3 will be described below with reference to the operation and effect of the embodiment of the present invention configured as described above.

A subscriber for using a free call first installs a pushbutton dialer 120 on a communication line of the phone 110.

Thereafter, when a subscriber for using a free call presses a specific button of the pushbutton dialer 120, the pushbutton dialer 120 calls a service provider having a phone number stored therein in advance.

At this time, the digital exchange system 150 of the service provider recognizes the output from the pushbutton dialer 120 to inform the call service providing system 160, and the call service providing system 160 picks up the handset of the telephone 110. The digital exchange system 150 to send out a message to the subscribers (for example, 'Toll free. Please use the local phone only. Please dial the phone number you want to call and press the asterisk (*)'). do.

Accordingly, when the subscriber presses the telephone number of the receiver to be called using the key panel of the telephone 110 with respect to the guide message in the digital switching system 150, the digital switching system 160 causes the telephone 110 to call. The calling party transmits the calling number to the call service providing system 160 and recognizes the calling number from the calling service providing system 160 to call the telephone number of the telephone 120 connected to the public telephone communication network 130.

At this time, when the digital switching system 150 recognizes the response signal from the telephone 120 to inform the call service providing system 160 and maintains the call line between the telephone 110, 140, the call service providing system 160 transmits an announcement message (eg, 'connected. Please listen to an advertisement and then call') to the telephone 110 or 120 through the digital switching system 150, respectively. Send it out.

Accordingly, when the transmission of the announcement and the advertising message has passed a predetermined time (for example, 30 seconds), the digital switching system 150 disconnects the call service providing system 160 from the telephone 110 and 120 and then connects with the subscriber. It connects the call line between the phone 110, 120 so that the call between the receiver.

Thereafter, when the talk time between the subscriber and the receiver has passed a predetermined time (3 minutes) including the transmission time of the announcement and the advertisement message, the digital switching system 150 receives the guidance message ('sorry') from the call service providing system 160. If you want to keep talking, you can listen to the advertisement and make one more call. 'Thank you.') With the phone 110 or 140 and then disconnect the call line between the phone 110 and 120. The advertisement service in the call service providing system 160 is transmitted.

Thereafter, when a predetermined time (30 seconds) for transmitting the announcement and the advertisement message has elapsed, the digital switching system 150 disconnects the call line between the call service providing system 160 and the telephones 110 and 120, and again with the subscriber. The call line between the phone 110, 120 is connected to enable the call between the receivers.

After that, when a predetermined time (3 minutes) has elapsed, including a time for transmitting a guide message and an advertisement message, the digital switching system 150 automatically establishes a call line between the telephones 110 and 120. To end the call.

That is, the above operation is a case in which the continuous call is limited to two free calls, which is briefly described as follows.

When the specific key of the pushbutton dialer 120 installed in the telephone 110 is pressed, the digital switching system 150 recognizes this and sends a guide message from the call service providing system 160 to the telephone 110. After transmitting the calling number from the call service providing system 160 to the call service providing system 160, the telephone 140 recognizes the calling number of the calling service providing system 160.

At this time, the digital switching system 150 that recognizes the response signal from the phone 140 transmits it to the call service providing system 160 and provides the call service in a state in which the call lines between the phones 110 and 140 are separated. Advertising messages from the system 160 are sent to the telephones 110 and 140, respectively, in which the call lines are separated.

Thereafter, the digital switching system 150 connects a call line between the phones 110 and 140 to enable a call between the subscriber and the receiver.

Thereafter, when a predetermined time (3 minutes) including an advertisement message transmission time elapses, the digital switching system 150 disconnects the call line between the telephones 110 and 140, and then the advertisement message from the call service providing system 160. To the phone 110,140.

Thereafter, when a predetermined time for the advertisement message has elapsed, a call line between the phones 110 and 140 is connected to enable a call between the subscriber and the receiver.

Thereafter, when a predetermined time (3 minutes) including the advertisement message transmission time elapses, the digital switching system 150 automatically disconnects the call line between the telephones 110 and 140 to terminate the call connection.

As described in detail above, the present invention provides a free call service so that subscribers and receivers can simultaneously listen to advertisements, thereby maximizing the advertisement efficiency of information media.
