Abstract

PURPOSE:To confirm surely a connection opposite party by sending an own dial number to a caller-side subscriber equipment during incoming call from an incoming-side subscriber equipment and allowing the caller side to collate the dial number and an outgoing dial number to start communication. CONSTITUTION:When an outgoing key of the own keyboard 8 at the inside of the subscriber equipment A1 is depressed, a signal processing section 7 generates a call signal and supplies it to a frame composition/decomposition section 6. The frame composition/decomposition section 6 combines an outgoing signal to a frame signal CHD and sends the result to an exchange 3 via a line interface section 5. Then an exchange 3 sends an incoming signal to a subscriber equipment B2, which sends an aknowledgement to the exchange 3. Then the exchange 3 sends a subscriber equipment class and an outgoing dial number from the subscriber equipment A1 and displays the outgoing dial number on a display section 9 of the subscriber equipment B2. The subscriber equipment B2 sends further a reply signal. Then the exchange 3 receives it and sends an incoming reply signal to the subscriber equipment A1. Then the incoming-side subscriber equipment B2 sends the own dial number to the caller side.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a connection method for connecting mutual home equipment via an exchange, and more specifically, communication is started after confirming the connection partner. be.

[Prior art] Fig. 6 is a system diagram of a conventional system for connecting home equipment via a switchboard, and Fig. 7 is shown in, for example, NTT Research and Practical Application Report Vol. 33, No. 8 (P79.P121). This is the connection sequence of conventional digital home equipment. In these figures, (1) indicates home equipment A, such as a facsimile, (
2) is the home equipment B, and (3) is the exchange.

Next, the connection operation between the household devices A(1) and B(2) will be explained. The connection from home device A (1) to home device B (2) is started when home device A (1) starts a calling operation and sends a calling signal to the exchange (3). On the other hand, when the exchange (3) receives the calling signal, it returns an acceptance signal. In response to this, home equipment A (1)
sends a home equipment class signal indicating the type of equipment, and after receiving a dialable signal from the exchange (3), the other party's home equipment B
(2) Sends the dial number. Next, switchboard (3)
sends an incoming call signal to home equipment B (2), and
2) On the condition that a confirmation signal is received from the home device A (1), the dial number of the home device A (1) and the dialed number from the calling party are transmitted. Home equipment B (2) determines whether the home equipment classes match, and if they match, it sends a response signal to the exchange (3) together with a display of the dialed number of the calling party. The exchange (3) sends the response signal from the home device B (2) to the home device A (1) as an incoming call response signal.

When the above sequence is completed, both devices become communicable and start communication.

[Problems to be Solved by the Invention] Since the conventional connection sequence is configured as described above, the called party's dialed number is displayed on the called home equipment B (2) and it is possible to confirm from where the call is coming from. However, even if a correct connection is made on the calling side, there is no response with the dialed number from the other party's home equipment, making the calling party unsure whether the connection was really made to the desired party. This poses a particular problem in protecting the confidentiality of communication data when in-home equipment is in automatic reception mode, handling data without human intervention.

This invention was made in order to solve the above-mentioned problems, and it is possible to confirm the dial number of the called side's home equipment with the calling side's home equipment during the connection operation, and to protect the confidentiality of communication data. Its purpose is to provide a method for connecting devices.

Means for Solving Problem E] The connection method according to the present invention causes the called home equipment to return its own dial number to the calling home equipment when a call is received, and the calling side checks the dialed number with the outgoing dial number. The communication is started when a match is found, and the process shifts to a disconnection operation when a match is found.

[Operation] If the outgoing dial number and the returned dial number do not match, a disconnection operation is performed and transmission is stopped.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a household device showing an embodiment of the present invention, FIG. 2 is a frame block diagram of a transmission path, FIG. 3 is a connection sequence, and FIG. 4 is an operational flow diagram of dial number verification.

In these figures, (4) is the line and (5) is the line (4
), and (6) is a line interface section consisting of a driver/receiver that interfaces with the frame shown in FIG. and a frame assembly and disassembly unit that assembles the information CH, (7)
is a signal processing section consisting of a microcomputer that processes the signal Cl-1, etc., (8) is a keyboard for inputting dial numbers, etc., (9) is a display section that displays dial numbers, etc., and (10) is an information This is a data processing unit that processes CH.

Next, the connection operation of the present invention will be explained.

When the home appliance A (1) presses the call key on its internal keyboard (8), the signal processing unit (7) generates a call signal and supplies it to the frame assembly/disassembly unit (6). The frame assembly/disassembly section (6) incorporates the calling signal into the frame signal CH (D) shown in FIG.
) to the exchange (3). When the exchange (3) receives the call signal, it transmits the reception signal to the signal CH of the frame.
(D) and sends it to home equipment A(1).

In the household device A (1), the frame assembly/disassembly section (6) disassembles the signal CH (D) and sends it to the signal processing section (7). The signal processing unit (7) discriminates the received signal, and then the in-home equipment A (1)
The same process as above is used to change the home equipment class to an exchange (
3). Below, switchboard (3) and home equipment A (
1) sends and receives dialable signals and dialed numbers.

At this time, the dialed number is displayed on the display section (9) as the destination number. Next, the exchange (3) connects the home equipment B (2)
It sends an incoming call signal to the caller, and sends a confirmation signal to the exchange (3) in the same manner as the calling side.

The exchange (3) then sends the home equipment class and calling dial number from home equipment A (1), and sends the home equipment class and calling dial number from home equipment B (2).
The outgoing dial number is displayed on the display section (9). In-house device B(2) further sends out a response signal. Then, the exchange (3) receives this and sends an incoming call response signal to the in-home equipment A (1).

Next, the called-side home equipment B(2) sends its own dial number to the calling side. Signal processing unit (7) of home equipment A (1)
), as shown in the operational flowchart of FIG. 4, the dialed number of the other party is taken in and displayed (11), and then the outgoing dialed number and the dialed number of the receiving party are compared (12). As a result of the comparison, if the numbers match, the communication operation using the information CH(B) is performed, and if they do not match, the communication operation is performed, and if they do not match, the communication operation is performed.

Although not shown in the figure, if the dialed number is not sent from the other party within a certain period of time during the verification operation described above, the operation will proceed to a disconnection operation, and if the manual key that passes the number verification operation is pressed, the operation will proceed to a communication operation. It also has a configuration.

Further, although the above embodiment describes the connection operation of digital home equipment, the present invention can be similarly applied to analog home equipment.

Figure 5 shows the connection sequence of analog home equipment. After the called home equipment B has looped on, it sends its own dial number to the calling party, and the calling home equipment A sends the outgoing dial number and the other party's dial number. The system verifies the dialed number from the terminal and controls communication or disconnection operations.

[Effects of the Invention] As described above, according to the present invention, the dialed number from the remote is sent to the calling side home equipment during the call receiving operation from the called home equipment, and the calling side combines this dial number and the outgoing dial. Since the system is configured to start communication by checking the number, it is possible to reliably confirm the connection partner, and it is also possible to reliably solve problems such as the contents of the communication being sent to an undesired party and the secret being leaked.
