Abstract

PURPOSE:To realize the interaction to many terminals by a message by fetching sub-address information from a sub-address added to a received ISDN number and storing it, and converting this information to the message. CONSTITUTION:In the case of reception, an ISDN interface part 2a fetches sub-address information from a received signal, and a processing part 7a retains this sub-address information in a storage part 3a, allows it to be subjected to code conversion by a message processing part 4a and displays it as message information on a display part 5a. The side for sending a message designates an ISDN number of the other party, and inputs the message whose transmission is desired. Subsequently, when the input is finished, an interactive device by an ISDN communication of a receiving side is called, and at the stage when an incoming response is sent back, the communication is disconnected. In such a way, since both of them repeat disconnection of the communication immediately after the incoming to the other party side, an interactive communication utilizing a sub-address can be executed, and the circuit occupied time is shortened, therefore, it becomes possible to execute a communication to many terminals.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In the embodiment of FIG. 1, the ISDN subaddress is used.
Use (Sub-address). An identification number called a subaddress is defined in the ISDN communication service. The sub-address is the number information added to the ISDN to identify the terminal or extension, and a specific terminal can be selected using this number information, and a maximum of 20 octets is allowed. ing.

The subaddress is originally used to distinguish the terminal of the other party. For example, it is possible to call only a specific terminal by giving a unique number to the other terminal.

By using this sub-address, it becomes possible to send a message to the sub-address part at the same time when the call arrives at the other terminal. Therefore, the side transmitting the message ends the transmission of the message to be transmitted at the time when the message arrives at the other terminal, and the time and the call charge become unnecessary.

The configuration and operation of this embodiment will be described below.

In FIG. 1, subscriber line terminal devices 1a and 1b are devices for transmitting a digital signal sent from a data terminal device to an ISDN network 10 of a digital line, and NTT is a subscriber's home. To install.

ISDN interface units 2a and 2
b is an ISDN from the communication signal (digital signal) of the ISDN communication sent from the subscriber line terminal device 1a or 1b.
The terminal identification number (sub-address) added to the ISDN number received through the DN communication procedure is taken out as sub-address information, and the terminal identification number (sub-address) is added to the ISDN number and transmitted as sub-address information.

The storage units 3a and 3b store the transmitted sub-address information or the received sub-address information.

The message processing units 4a and 4b convert the sub-address information into message information that can be understood by the user, and convert the message information into sub-address information. In ISDN, the numeral 1 is not transmitted as it is, but converted into an IA5 character code (see CCITT Recommendation T50) and transmitted. For example, the number 1 is IA5
It is expressed as 31 in the character code. The ISDN telephone converts the IA5 character code into a number and displays it. Therefore, when the user wants to send 1, the message processing units 4a and 4b perform a process of converting it into the IA5 character code 31.

The message display portions 5a and 5b display a plurality of lines of messages. The message input units 6a and 6b input a message.

Next, the operation of the interactive apparatus based on ISDN communication configured as described above will be described.

In the case of transmission, the sender of the message inputs the message from the message input section 6a or 6b. The message input to the message input unit 6a or 6b is input to the processing unit 7a or 7b having the storage unit 3a or 3b and the message processing unit 4a or 4b, and is sent to the message display unit 5a or 5b. Is displayed as. Also, it is sent to the message processing unit 4a or 4b, encoded there and stored in the storage unit 3a or 3b as sub-address information.

When the sender of the message finishes inputting the message and starts transmission, the subaddress information stored in the storage unit 3a or 3b is sent to the ISDN interface unit 2a or 2b.

ISDN interface section 2a or 2
b adds the input sub-address information to the ISDN number and transmits it as a sub-address via the ISDN communication procedure.

In the case of reception, the ISDN interface section 2a or 2b is connected to the subscriber line terminal device 1a or 1
Sub-address information is extracted from the communication signal (digital signal) received from b and sent to the processing unit 7a or 7b. The processing unit 7a or 7b stores the input sub-address information in the storage unit 3a or 3b, converts the code in the message processing unit 4a or 4b, and sends it as message information to the message display unit 5a or 5b for display.

In the above-mentioned operation, the message determines the code table (encryption) and uses it, or uses the IA5 character code as it is.

The message sending side uses the ISDN communication interactive device and the ISDN communication
Specify the DN number and enter the message you want to send using the input device. When the input of the message is completed, the transmission is activated to call the interactive device on the receiving side by ISDN communication.

When the other party is not communicating, an incoming call response is returned. Since the transmission of the message is completed at that stage, the communication is disconnected.

The receiving side is informed that a message has arrived by the interactive device by the ISDN communication, and the message is displayed for each incoming.

Thus, by repeating the operation of disconnecting the communication as soon as the call is received by the other party,
It becomes possible to establish interactive communication using the subaddress. Also, by disconnecting the communication as soon as the call arrives at the other party, the time occupied by the line is shortened, so that communication from other terminals can be received and communication with more terminals than before is possible. It will be possible.

It is assumed that the ISDN communication dialogue device establishes a dialogue by characters (message) by performing message communication between the same dialogue devices. When the other party receiving the message is in communication, the transmission is temporarily stopped, and then the same sub-address information is transmitted again, and the retransmission is automatically performed.

Further, since the amount of messages that can be transmitted at one time by the subscriber line terminal device is limited, when the subaddress information exceeds a predetermined length, the subaddress information is divided into a plurality of parts, It has a chain function that can send and receive them continuously. This can be realized by performing processing such as adding an end bit to the end of the sub address information. In this way, it is possible to treat a long message as if it was sent and received once.
