Abstract

PURPOSE:To eliminate the need for the reply to an incoming call from a called party by displaying the information sent from a caller side on a display section of the called party as character information via an ISDN network with a protocol signal. CONSTITUTION:Message information inputted by a caller is converted into a character code by an input device 1 and outputted to a character transmission edit section 2. The character code is composed into a user.user element by the character transmission edit section 2. A data transmission section 3 superimposes the inputted user.user element onto a protocol signal and sends the result to an ISDN network A. A data demultiplex section 6 extracts and demultiplexes the user.user element from the protocol signal coming from the network A to output the character code. The outputted character code is edited by a character display edit section 5. The edited character code is converted into character information and displayed on a display device 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ISDN-compatible digital telephone capable of communicating character information such as handwritten characters.

[Prior Art] Conventionally, ISDN-compatible digital telephones (hereinafter referred to as digital telephones) have been designed to make and receive calls using a dial pad and keys for making and receiving calls.
Message information is entered into a digital telephone using a dial pad. [Problems to be Solved by the Invention] In the above-mentioned conventional digital telephone, when message information was sent via the B channel, it was necessary for the called party to respond by performing an incoming call operation.

Furthermore, since data is entered by operating a dial pad, there are problems in that operating the dial pad is complicated and time consuming, and there are restrictions on the types of characters that can be input using the dial pad. [Means for Solving the Problems] The ISDN compatible digital telephone of the present invention has the following means. a) An input device section that converts input information into a character code, b) A character sending editing section that assembles the character code into user/user elements, C) A protocol signal including l-f/user elements is sent to ISDN via the D channel. d) A data separation unit that separates the user/user element from the protocol signal received from the ISDrll and outputs a character code; e) A character output from the data separation unit. a character display editing section for editing one code; f) a display device for displaying character information corresponding to the m collection of character codes; [Operation] In the ISDN compatible digital telephone on the calling party's side, information input into the input device section is converted into a character code, and assembled into a user/user element in the character exit editing section. This user-user element is connected to the IS via the D channel by a protocol signal in the data sending section.
It is sent to the DN network.

ISDN on the ISDN-compatible digital telephone on the called party's side.
The user/user element is separated from the protocol signal input from the DNlq to the data separation unit and a character code is output.This character code is edited in the character display editing unit and converted from the character code to character information on the display. Is displayed. Therefore, the information sent from the calling party is received by the called party via the ISDN'II1 according to the protocol signal, and is displayed as character information on the display unit.

[Example] Next, this invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the ISDN compatible digital telephone of the present invention. 10 shows this ISDN compatible digital telephone. (2) is an input device section that inputs a message to be sent to a destination and converts the information of the input message into a character code corresponding to the message. Reference numeral 2 denotes a character sending guide section which assembles character codes input from the input device section 1 into users/user elements. What is a user/user element? ISDN
This is an element that sends a message to the other party when making a call or disconnecting. Reference numeral 3 denotes a data sending unit that sends out a protocol signal including users and user elements onto the D channel of the ISDN network A.

Reference numeral 4 denotes a data separation unit which separates users and user elements from the protocol signal input from the D channel of the ISDNW 4A and outputs character codes. 5 is a character display editing section that edits the character code input from the data separation section 4; and 6 is a display section that displays character information corresponding to the character code input from the character display editing section 5.

FIGS. 2 and 3 are flowcharts showing the operation of the ISDN compatible digital telephone according to the present invention, and the following description will be made according to these flowcharts. The flowchart in FIG. 2 shows the operation of the calling party's digital telephone.

That is, the calling party inputs information about a message to be sent to the called party from the input device section 1 (step 10l). The input message information is converted into a character code by the input device section 1 and output to the character sending and editing section 2. The character code is assembled into a user element by the character sending editing section 2. On the other hand, following the message, the calling party enters the subscriber number of the called party in the normal procedure (step 102). The data sending unit 3 sends the user/user element inputted from the character sending editing unit 2 onto the protocol signal to the ISDN network A via the D channel according to the subscriber number specified in step 102.

The flowchart in FIG. 3 shows the operation of the called party's digital telephone.

That is, when a protocol signal arrives from ISDN lilA, the ringer of the called party's digital telephone rings to notify the user of the incoming call, and the data separation unit 4 extracts and separates the user/user element from the incoming protocol signal. The output character code is edited by the character display editing section 5 (step 202). The edited character code is converted into character information and displayed on the display 6. (Step 203).

Note that various means can be used as the input device section 1 in this embodiment. For example, an IC card that outputs a character code corresponding to predetermined character information stored in advance can be used. In addition, the input device unit 1 may include a handwritten character input device that outputs character information corresponding to read handwritten characters, and a character recognition unit that converts the output character information into a character code. . Furthermore, instead of this handwritten character input device, an image scanner, dial pad, keyboard, magnetic card reader, barcode reader, and voice input device can also be used. In this case, various types of means can be arbitrarily selected as the input device section l as required. That is, for example, a method that allows message information to be input in a short period of time or a method that has few restrictions on the types of characters that can be sent can be arbitrarily selected as needed. [Effects of the Invention] As explained above, according to the ISDN-compatible digital telephone of the present invention, in the ISDN-compatible digital telephone on the caller's side, the information input to the input device section is converted into a character code, and the information is converted into a character code. It is assembled into users and user elements in the sending editing department. This user/user element is sent to the ISDNm via the D channel by a protocol signal in the data sending section. I on the called party's side
In SDN-compatible digital telephones, user signals are input from the ISDN network to the data separation unit.
User elements are separated and character codes are output. This character code is edited in the character display editing section, converted into character information and displayed on the display.

Therefore, the information transmitted from the calling party is transmitted via the ISDN network to the called party using protocol signals and is displayed as text information on the display, so that the called party can respond to the call. There's no need to.

In addition, since it is possible to use a wide variety of methods as an input device, methods that allow message information to be entered in a short period of time or methods that have fewer restrictions on the types of characters that can be sent can be adopted as necessary. It becomes possible to do so.
