Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image subscriber identification method for identifying a subscriber requesting an image service in an image exchange that accommodates an image line.

Conventionally, when performing an image response service in which a subscriber calls a center and the center provides an image service, a method was used in which links for telephone exchange and image exchange were placed side by side and controlled simultaneously. In this case, a dedicated 4-wire exchange was used that combined telephone and image signals, which lacked flexibility and economy.

To solve this problem, the existing telephone exchange network is used to call the center and send control signals to the center, and accommodates subscriber terminals such as push-button telephones. A method has been considered in which an image exchange network is provided at the center, and image information is sent from the center to a receiver provided corresponding to the subscriber terminal, thereby providing an image response service.

However, when this service is provided using an existing telephone exchange network, there is a drawback in that the existing subscriber exchange requires extensive modification as will be explained in FIG. 1 below.

In FIG. 1, Ls is an existing telephone exchange, VEX is an image exchange, and SR8 is a concentrating relay station installed when the image center is remote.

The subscriber is provided with a TV receiver (image terminal) for receiving the image response service and a push-button telephone (control terminal) for control signals, each of which is accommodated in the VEX and LS.

When a subscriber wants to receive an image response service, after detecting a call from the station and a code for accessing the image response service network in the LS, the control device C0NT sends a call from the station to the image response service network via the telephone network ANW. Select and connect the outgoing trunk OGT of the train, and start the image exchanger VEX from the OGT.

On the other hand, in VEX, a calling subscriber information ID is required to identify the TV corresponding to the calling subscriber and to send the calling subscriber information to the center for purposes such as billing.

For this purpose, in the LS, under the control of C0NT, the originating sender O8 sends the ID of the calling subscriber identified from the accommodation location information of the station via the OGT.

On the other hand, in VEX, the controller CC controls the repeater REP.
After detecting that the register sender R8 has been activated, it connects to the register sender R8 and receives the ID signal.

As a result, the CC connects the TV corresponding to the calling party and the line of SR8 via the image network VNW, and transmits the calling subscriber information ID and the information of the selectively connected image line from R8 to SR8 via REP. Send to.

This allows the TV and station to use VEX and It passes through the LS and is connected to the center via SR8.

After connecting to the center, O8 and R8 switch to OGT for the next call.
, REP, respectively.

The control signal for the subsequent image response service is SR8.
LS and VEX only monitor the end of the call.

As mentioned above, this method requires the addition of hardware to the telephone exchange LS for identifying and transmitting calling subscriber information, and when using an existing exchange network, extensive modification and addition of functions to the existing exchange are required. It becomes necessary.

An object of the present invention is to greatly reduce the need for modification and addition of functions to the above-mentioned existing switching equipment, and to economically provide an image response service.

In order to achieve the above object, the present invention provides an image exchanger VEX
In addition, by providing a code generating device using image signals and transmitting subscriber identification information etc. from a control terminal, it is not necessary to provide the telephone exchange LS with a function of creating and transmitting calling subscriber information.

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 2, VDS is an image signal generating device provided according to the present invention, and other symbols are the same as in FIG. 1.

First, a subscriber who wishes to provide an image response service makes a call from a push-button telephone device, which is a control terminal, and inputs (dials) an image response network access code. The outgoing trunk OGT of the train is selectively activated, and in response to the response from the image exchange VEX, the station and OGT are connected via the telephone network.

On the other hand, in VEX, repeater RFP and register sender R8 are connected.

This completes the route -ANW-OGT-REP-R8.

Here, a subscriber identification number ID such as one's own telephone number or image service number is input (dial) from TF and I, and this is received by R8 of VEX.

In VEX, based on the received ID information, the image signal generating device VDS is connected to the TV receiver, which is the corresponding image terminal, via the image network VNW.

Here, the control device CC sends an arbitrary code to the VDS, which converts it into an image signal and displays it on the TV.
to be displayed.

When the subscriber in question dials the code displayed on the TV, the information is sent to ANW-OGT-
Sent via REP-CC route, CC in VEX
Then, by comparing the code sent to the VDS with the information input from the equipment, it is confirmed that the equipment and the TV are the same subscriber.

After confirmation, R8 receives and transmits the calling subscriber information and the information of the image line selectively connected via the TV and VNW from the CC to the concentrator relay station SR8 via the RFP.

The subsequent operations are the same as those shown in FIG.

As described above, according to the present invention, by inputting identification information of a calling subscriber from a telephone that is a control terminal, it can be realized without providing the telephone exchange with a function for creating and transmitting the identification information, etc. This has the advantage that the telephone exchange can be used as is for image response services.

Furthermore, by providing the image exchanger with an arbitrary code generation and verification function and an image signal generator, the control terminals and image terminals of different subscribers will not be connected to the center, and unauthorized use can be prevented. It has various effects such as.

Claims (1)

[Claims] 1 A subscriber in which the image exchange that accommodates the subscriber's image terminal and the telephone exchange that accommodates the subscriber's control terminal are separated, and the telephone exchange controls the connection of the image line by sending control information to the image exchange. This is an image response service, in which the image exchanger receives a subscriber identification number sent from a control terminal via the telephone exchange, and then an image signal generator installed in the image exchanger generates an image corresponding to the identification number. This is a subscriber identification method in which an arbitrary code is displayed on the terminal and the subscriber enters the code from the control terminal to identify the subscriber's control terminal and the image terminal.
