Abstract

PURPOSE:To control the call reception mode of a called data terminal equipment in response to a state from a caller data terminal equipment. CONSTITUTION:In the case of setup from a caller data terminal equipment 10 to a called data terminal equipment, a mode setting signal to set the call reception mode to the manual or automatic call reception for the call reception mode of the called data terminal equipment 20 is inserted into a subaddress of a setup message and the resulting message is sent. Thus, the called data terminal equipment 20 receiving the setup message extracts a mode setting signal from the subaddress of the setup message to discriminate whether the mode setting signal is the manual call reception signal or the automatic call reception signal. As a result, in the case of the manual call reception mode, a call signal rings to reply the caller by the reply operation of the operator and in the case of the automatic call reception mode, the call is replied by the automatic reply and then the transmitted data are received.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inter-data terminal control system in an ISDN line, and particularly to an ISDN line applied when controlling the incoming call mode of a data terminal device on the caller side from a data terminal device on the callee side. The inter-data terminal control method in.

[0002]

[Prior Art] Conventionally, ISDN (Integrated Services Digital Network)
The data terminal device on the line is the data terminal device on the receiving side for the call setting from the data terminal device on the calling side,
There are a manual incoming call mode in which a response is made by the operator's response operation, and an automatic incoming call mode in which the data terminal device on the called side automatically responds. Each of these incoming modes is configured to be set by the operator of the incoming data terminal device, and cannot be controlled from the outgoing data terminal device.

In such a conventional data terminal device on an ISDN line, first, in the data terminal device on the called side, when the operator sets the incoming mode to the manual incoming mode, the data terminal device on the calling side calls. When a call setup message is sent over the ISDN line to set up,
The data terminal device on the called side receives the call setup message and sounds a ringing signal. As a result, when the operator on the receiving side responds to the data terminal device, a response message is sent from the data terminal device on the receiving side to the data terminal device on the calling side in response to the call setting message from the calling side. It Then, the data terminal device on the sending side which receives this response message sends desired data via the ISDN line by the operation. As a result, the transmission data is received by the data terminal device on the receiving side via the ISDN line, and the information represented by the data is displayed on the display of the device on the receiving side.

Further, when the data terminal device on the receiving side is set to the automatic receiving mode, when a call is set up from the data terminal device on the calling side via the ISDN line, the data terminal device on the receiving side automatically sets. The response returns a response message to the call setup message. As a result, the call setting is established and desired data is transmitted from the data terminal device on the calling side through the ISDN line. In the data terminal device on the receiving side that receives the transmission data, the received data is stored in a storage device or the like, and the operator later performs a read operation and displays it on a display or the like to reproduce the information.

[0005]

As described above, in the prior art, the data terminal device on the receiving side determines the incoming mode, so that the data terminal on the receiving side receives data from the data sending side. Unable to control the device,
There is a problem in that the data may have to be sent to the data terminal device on the receiving side that is not in the desired state on the transmitting side. For example, when sending data that does not require urgency, the callee's mode can be either manual call or automatic call. There was a problem that I couldn't hand over to the other party immediately.

The present invention solves the above-mentioned drawbacks of the prior art, and the data on the ISDN line can be freely set from the data terminal device on the originating side through the ISDN line to the incoming mode of the data terminal device on the receiving side. It is intended to provide an inter-terminal control method.

[0007]

In order to solve the above-mentioned problems, the data terminal control system for an ISDN line according to the present invention changes from a data terminal device on the calling side to a data terminal device on the called side connected to the ISDN line. When setting up a call, the data terminal device on the originating side controls the incoming mode of the data terminal device on the receiving side through the ISDN line to transmit data from the data terminal device on the originating side. When a call is set up from the device to the data terminal device on the receiving side via the ISDN line, a subaddress of the call setup message is used to distinguish the receiving mode of the data terminal device on the receiving side from the automatic receiving mode and the manual receiving mode. The mode setting signal of is sent to the ISDN line, and when this call setting message is received by the receiving side data terminal device, this receiving side data terminal device , The mode setting signal is extracted from the subaddress of the call setting message received through the ISDN line, and it is determined whether the mode setting signal represents the manual call receiving mode or the automatic call receiving mode. , The data terminal is activated by the operator's response operation to respond to the data terminal device on the calling side, and if the mode setting signal indicates the automatic incoming call mode, the call is sent automatically. It responds to the data terminal device on the side.

In this case, the data terminal device on the receiving side has a display means for displaying the information represented by the transmission data from the data terminal device on the calling side after the call is set up, and the data terminal device on the receiving side. When a call setting message is received from the data terminal device on the calling side, when the mode setting signal of the sub address indicates a manual incoming call, the ringing signal is sounded and the display means is activated to prepare for data display. It is characterized by doing.

On the other hand, when the data terminal device on the ISDN line according to the present invention sets up a call to the data terminal device on the other side via the ISDN line, it controls the incoming mode of the data terminal device on the other side to obtain the desired data. In the data terminal device in the ISDN line that transmits the data, the main address generating means for generating the main address when setting up the call to the data terminal device of the other side, and the receiving mode of the data terminal device of the other side are the automatic call receiving mode and the manual call receiving. It has a sub-address setting means for generating a predetermined mode setting signal for distinguishing between modes and a transmitting means for transmitting a call setting message including a main address and a sub-address to the data terminal device on the partner side via the ISDN line. It is characterized by

Further, the data terminal device in the ISDN line according to the present invention responds to the call setting from the data terminal device on the transmitting side transmitted via the ISDN line, and the data in the ISDN line whose incoming mode is controlled is controlled. In the terminal device, a signal extracting means for extracting a mode setting signal indicating either the manual call receiving mode or the automatic call receiving mode from the subaddress of the call setting message at the time of call setting received from the data terminal device on the calling side via the ISDN line. And a signal discriminating means for discriminating whether the mode setting signal extracted by the signal extracting means represents the manual incoming mode or the automatic incoming mode, and the mode setting signal discriminated by the signal determining means indicates the manual incoming mode. The ringing signal generating means for ringing the ringing signal of the device itself and the mode setting signal discriminated by the signal discriminating means are In the case of representing the dynamic incoming / outgoing mode, automatic response means for responding to the call setting of the data terminal device on the calling side, and data transmitted from the data terminal device on the calling side after the response of the automatic answering device are received and stored And a storage means for storing the data.

In this case, the data terminal device further includes a display means for displaying data transmitted from the data terminal device on the calling side after the call setting and a mode setting signal discriminated by the signal discriminating means indicates the manual termination mode. Display starting means for starting the display means in the case of

[0012]

According to the inter-data terminal control method for an ISDN line according to the present invention, when a call is made from a data terminal device on the originating side, a main address for calling the data terminal device on the other side and its receiving mode When a sub address including a mode setting signal for distinguishing between the main address and the sub address is input, a call setting message including the main address and the sub address
It is transmitted to the data terminal device on the called side via the line. Upon receiving the call setup message, the data terminal device on the receiving side extracts the mode setup signal included in the subaddress of the call setup message. Thus, when the mode setting signal indicates a manual incoming call, the ringing signal is sounded, and when the mode setting signal is provided, it is activated.

As a result, when the operator on the receiving side performs a response operation on the data terminal device, a response message to the call setting is transmitted to the data terminal device on the transmitting side via the ISDN line, and the data on the transmitting side receiving the message is received. Data is transmitted from the terminal device. As a result, the receiving side can receive the data immediately by displaying the transmission data from the transmitting side on the display or the like.

Further, the call setup message from the calling side is
If the sub-address includes a mode setting signal for making an automatic incoming call, the data terminal device on the called side returns a response message to the calling side via the ISDN line by an automatic response to the call setting message. As a result, when the data is transmitted from the calling side through the ISDN line, the receiving side stores the received data in the storage means. Then, the operator on the receiving side later operates the data terminal device to reproduce and display the data read from the storage means on a display or the like.

[0015]

The ISDN according to the present invention will now be described with reference to the accompanying drawings.
An embodiment of the control method between data terminals on a line will be described in detail. FIG. 1 shows a schematic configuration of a communication system to which an inter-data terminal control system in an ISDN line according to this embodiment is applied. The communication system in this embodiment is

0,20 is connected to the ISDN line 30 of (2B + D) channel consisting of two communication channels and one control channel,
Data communication is performed via the ISDN network including 40. In particular, in this embodiment, when a call is made from the data terminal device 10 on the calling side, a mode setting signal for controlling the incoming mode of the called side is inserted into the call setting message and transmitted, and this is received. The incoming mode is controlled by the data terminal device 20 on the incoming side. When the controlled incoming mode is a manual incoming call, the data terminal device 20 on the incoming side responds to the call setting on the outgoing side by the operator performing a response operation by pressing a port button or the like, and in the case of an automatic incoming call. Respond with an automatic response.

More specifically, as shown in FIG. 2, the data terminal devices 10 and 20 in this embodiment include a transmission circuit 100, a reception circuit 110, a main address generation unit 112, a sub address setting unit 114, and a signal extraction unit. 116, the signal determination unit 118,
Call signal generation unit 120, automatic response unit 122, and storage unit 124
And a display control circuit 124. Transmit circuit 100 is I
A circuit for transmitting a call setup message or a response message at the time of call setup or transmission data after call setup to the SDN line 30 toward the data terminal device on the partner side. Receiver circuit
Reference numeral 110 is a circuit for receiving a call setup message or a response message at the time of call setup or transmission data after the call setup from the ISDN line 30.

The main address generation unit 112 is a signal generation circuit that generates a main address when setting up a call to the data terminal device on the partner side. The sub-address setting unit 114 is a signal generation circuit that generates a predetermined mode setting signal for distinguishing the incoming mode of the data terminal device of the other party into the automatic incoming mode and the manual incoming mode. A mode setting signal such as "1234" is generated as a sub-address when the data terminal device on the side is set to the manual call reception mode, and a mode in which "0000" or no sub-address is set when the automatic reception mode is set. Generate a setting signal.

The signal extraction unit 116 is a sub-address extraction unit that extracts a mode setting signal indicating either a manual call receiving mode or an automatic call receiving mode from a sub address of a call setting message received by the receiving circuit 110 when setting a call. .
The signal discriminating unit 118 is a discriminating unit for discriminating whether the mode setting signal extracted by the signal extracting unit 116 represents the manual incoming call mode or the automatic incoming call mode. Call signal generator
Reference numeral 118 generates a calling signal of its own device when the mode setting signal judged by the signal judging unit 116 indicates the manual incoming mode, and causes the calling device such as a tone ringer to ring.

When the mode setting signal discriminated by the signal discriminating unit 116 indicates the automatic incoming mode, the automatic response unit 120 generates and transmits a response message responding to the call setting of the data terminal device on the calling side. This is a signal generation unit for sending to the circuit 110. The storage unit 122 is a data storage unit that receives and stores the data transmitted from the data terminal device on the transmission side after the automatic response unit 120 responds. The display control unit 124 is a control circuit that displays on the display the data received by the receiving circuit 110 or the data stored in the storage unit 122. In particular, the mode setting signal determined by the signal determining unit 116 indicates the manual call receiving mode. When the automatic incoming call is received, the display is activated by the reproduction operation of the operator after the reception.

In such a structure, according to this embodiment
A control method between data terminals in an ISDN line will be described with reference to FIGS. First, in FIG. 3, in the data terminal device 10 (terminal A in FIG. 3) on the originating side, the operator inputs the destination number and the distinction between the receiving mode on the destination side via a keyboard or the like. As a result, the main address generation unit 112 of the data terminal device 10 generates the main address indicating the destination number, and the sub address setting unit 114 generates the sub address including the mode setting signal. Then
When the operator makes a call operation, a call setup message (SETUP) including a main address and a sub address is sent via the ISDN network including the ISDN line to the data terminal device 20 (FIG.
Then it is sent to terminal B). At this time, by the time the terminal B responds, a setting signal (CALL PROG) indicating that the call is being set up is returned from the ISDN network to the originating data terminal device 10.

Next, in the data terminal device 20 on the receiving side,
In response to the mode setting signal of the sub address included in the call setting message, that is, when the mode setting signal of the sub address indicates a manual incoming call, the operator's answer operation, and when it indicates an automatic incoming call, the answer message ( C
ONN) is returned to the data terminal device 10 on the originating side via the ISDN network.

More specifically, as shown in FIG. 4, when the data terminal device 20 on the receiving side receives the call setting message in its receiving circuit 110, the signal extracting section 112 extracts the mode setting signal of the sub address. , The signal determination unit 114 determines whether or not the signal is, for example, "1234" (step ST1
0). If the mode setting signal is "1234", the signal determination unit 114 determines that it is a manual incoming call and proceeds to step ST12, and if the number is different, it is determined that it is an automatic incoming call and proceeds to step ST14. .

In the data terminal device 20 that has proceeded to step ST12, as shown in FIG. 5, the display control unit 124 further activates the display in step 120, and then in step ST122, the call signal generation unit 118 transmits the call signal. Sound. As a result, when the operator presses the port button in step ST124, a signal indicating whether or not the device itself is in a receivable state, that is, a device such as a display connected to the terminal is ready (ER ) Is turned on and send a response message.

On the other hand, in the data terminal device 20 which has proceeded to step ST14, as shown in FIG. 6, the automatic response section 120 and the storage section 122 are activated, and then at step ST140, the storage section 122 is turned on as described above. The ER signal is used to confirm whether or not the response message has been sent. In these cases, when the ER signal is not transmitted from each device even after a predetermined time elapses, that is, when the display or the storage unit 122 does not turn on even after a predetermined time elapses, step ST126 or step ST126, respectively. In ST142, it is judged as a timeout and the communication by the call setting is disconnected.

Returning to FIG. 3 again, the data terminal device 10 on the calling side, which has received the response message from the data terminal device 20 on the called side, appropriately sends an identification signal (CONN ACK) indicating that connection is possible. While transmitting, desired data is transmitted subsequently. As a result, in the data terminal device 20 on the receiving side that has received the data via the ISDN network, in the case of a manual incoming call, the character or graphic information represented by the received data is immediately displayed on the display to the operator on the receiving side. show. In the case of an automatic incoming call, it is stored in the storage unit 122 and later displayed on the display by a reproduction operation of the operator on the incoming side.

As described above, in this embodiment, when the call is set on the calling side, the mode setting signal for controlling the incoming mode of the data terminal device 20 on the called side is inserted into the subaddress of the call setting message and transmitted. It is possible to control the data terminal device on the partner side to transmit data by distinguishing whether the caller side needs urgently or not. Furthermore, in the present embodiment, the display is automatically turned on when the data terminal device 20 on the receiving side receives the mode setting signal indicating the manual incoming mode. It is possible to respond by a simple operation only by pressing.

In the above embodiment, the display is automatically turned on when a manual call is received, but the present invention does not necessarily have to have the function. in this case,
As shown in FIG. 7, using the inter-data-terminal control method omitting step ST120 in FIG. 5, if either the display or the storage unit is turned on in step ST124, that is, if reception is possible, The response message may be returned.

[0028]

As described above, the ISDN according to the present invention
According to the data terminal-to-data terminal control method in the line, when setting the call on the calling side, the mode setting signal for controlling the call receiving mode of the data terminal device on the called side is inserted into the subaddress of the call setting message and transmitted. There is an effect that the data terminal device on the partner side can be controlled and data can be transmitted separately depending on whether an emergency is required or not.

Further, since the display is automatically activated when the data terminal device on the receiving side receives the mode setting signal indicating the manual receiving mode, the operation for the manual receiving is simplified. There is an effect that can be.
