Then the processing node uses a transmission/reception means 20a to receive a D channel packet via the interface circuit 1, the control means 20 recognizes the message transmission request, the message information corresponding to the message number is extracted from a storage means 30 and converted into a dot pattern by using a conversion means 40.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field to which the invention pertains The present invention relates to a system that is accommodated in a digital network or a local area network via a digital subscriber line that time-division multiplexes transmission of information channels and signal channels, and that -End
The present invention relates to a message transfer method that uses a data transfer function to transfer a message expressed in Kanji characters via a processing node that has a database of Kanji-based message messages.

(2) Prior Art A conventional telephone equipped with this type of message sending function is a personal computer telephone that combines and integrates a personal computer and a telephone. An example of the configuration of a personal computer telephone is shown in FIG. In Figure 6, 10
Reference numeral 1 denotes a telephone unit consisting of a dial transmission circuit, a monitoring detection circuit, a telephone communication circuit, etc., 102 a handset, and 103 a modem unit.

104 is a display such as a CRT, 105 is a full keyboard, 106 is an auxiliary memory such as a floppy disk, 1
07 is a character ROM that generates kanji fonts, 10
Reference numeral 8 denotes a personal computer body that controls the elements 101, 103 to 107.

First, when creating a message, use the kana-to-kanji conversion function or the romaji-to-kanji conversion function of the main unit 108 to convert the kana or romaji input from the keyboard 105 into the ROM 10.
7 to create a message by converting it into a kanji font and sequentially displaying it on the display 104, and storing it in the auxiliary memory 10.
6. Memorize and retain. Next, if the message mode is set, the main unit 108 will respond to incoming calls during the message mode.
When the communication link between the modems is established, the modem unit 103 is activated and the modem signal is exchanged with the two devices, and the modem-to-modem communication link between the devices is established.
The message stored in 06 is transferred to the calling party as character code information, and the call is disconnected. On the originating side, based on the received character code information, the main unit 1
08 uses the ROM 107 to convert the message into a kanji font, and displays the message in kanji on the second display 104.

Conventional PC telephones have such a configuration, and therefore have the following drawbacks.

(2) It requires hardware such as a character ROM for generating kanji fonts, a full keyboard, and a modem, as well as a kana-to-kanji or romaji-to-kanji conversion function (software), making the device expensive and difficult to miniaturize.

■ The procedure for creating a recorded message is cumbersome, and if you suddenly go out for business other than the registered message, you will not be able to create a recorded message corresponding to the other matter, which is inconvenient. .

■ Since the forwarding of the recorded message is performed automatically after the incoming call is answered and the modem procedure is established, the first caller will be charged a fee, and if the second caller is not using a similar computer phone, the message will not be forwarded ( This will result in you being charged a fee.

Furthermore, in conventional analog networks, because the device cannot tell who is receiving the call, it is not possible to develop advanced services such as changing the message depending on whether the caller is away or the person is not home, which is in high demand these days.

(3) Purpose of the Invention The purpose of the present invention is to solve two or more drawbacks, and to make it possible to transfer messages using kanji expressions without placing any operational burden on the user, by utilizing the functions of digital networks. Our objective is to provide digital telephones that are smaller and more economical.

By using the end-end data transfer function (D channel packet or user data transfer) and caller ID notification function using the signal channel of the digital network or digital local area network, the digital telephone side only transmits the telephone number and message number. 2.When a call arrives while the message mode is set, the caller ID is checked against the registered phone number, and if a match is made, a database of messages including kanji expressions is created via the D channel. The node is automatically accessed and the caller ID and message number are transferred to request the sender to send the message, and the processing node extracts the message information from the message number, converts it to dot pattern information, and sends the same message. D channel End-E
The main feature is that the message is transferred to the calling party based on the caller ID using the nd data transfer function.

End-end data transmitting/receiving means such as packets or user data; 30 is a storage means for storing various messages (fixed or semi-fixed forms) including kanji characters in correspondence with message numbers as a database; 40 is a storage means 30 is a conversion means for converting message character code information stored in 30 into dot pattern information.

Also, Fig. 3 shows an example of the frame structure of a call control signal exchanged between a terminal and the network, and Fig. 4 shows a D channel packet when requesting message transmission from digital telephone A to processing node head digital charger B. Example of frame structure in case 5th
The figure shows an example of the frame structure of a D channel packet when a processing node transmits a message consisting of a dot pattern to digital telephone B at the request of digital telephone A.

Next, the operation will be explained. First, digital telephone A (D
- When setting A) to message mode, input means 4
When the function key (for example, message setting key) is pressed, the control unit 2 starts the setting operation.

Subsequent inputs of a telephone number and a message number by dialing the input means 4 are received, and the information is displayed on the display means 3 for the user to confirm, and is also stored in the storage means 6. Note that in this setting procedure, in addition to inputting a fixed form message in which only the message number is entered using a target table of message numbers and message contents, for example, you can input a message such as "I will be away from what time to what time..." in addition to the message number. There is a semi-formal message input that adds simple information such as the time of the case. Furthermore, when the telephone has an electronic telephone directory, only message information needs to be input. It is also possible to input a different message number for each phone number. After inputting the telephone number and message number in this way, the control section 2 enters the message mode by pressing a function key (for example, the message mode key) of the input means 4.

Next, the operation of transmitting a message via the processing node in response to an incoming call in the message mode will be described. When in the message mode, there is an incoming call (transmitted on the D channel according to the formant shown in FIG. 3 and transmitted to the control unit 2 via the interface circuit 1) from the digital telephone B (D-position B).

The control unit 2 compares the calling party number (caller ID: telephone number of D-place-B) notified from the network side at the same time as the arrival of the call with the telephone number stored in the storage means 6 using the collation means 2b. This is done by When the verification is successful, the control unit 2 accesses the processing node using the end-end data transfer function of the D channel using the automatic sending/receiving means 2a in accordance with the format shown in FIG. The message transmission request is made by transferring the number and the message number corresponding to the telephone number stored in the storage means 6.

The processing node receives the D channel packet shown in FIG. 4 by the sending/receiving means 20a via the interface circuit 1, recognizes that the control means 20 is a request to send a message, and stores the message number from the storage means 30. The message information corresponding to the message information is extracted and converted into a dot pattern using the conversion means 40. Next, the control means 20 transmits the message information converted into a dot pattern to the D-place B by the transmitting/receiving means 20a using the D channel packet shown in FIG.

D-Place B transmits and transmits via interface circuit 1.
receiving the D channel packet by the receiving means 2a;
The control section 2 recognizes that it is a message notification, etc., and displays it on the display means 3.

Through the above series of operations, the message from D-place A containing the kanji expression in D-place B is conveyed.

When inputting the above message number, D-A requests the processing node to send the message list and the message itself as door-to-pattern information using the D channel, and displays the message on the 2nd display. You can also select a message number after checking it.

Furthermore, in the above explanation, the case where the message is changed depending on who is receiving the call has been described.

For phone numbers for which you do not enter a message number in message mode, you can also set a ring tone and use it as an answering machine. Furthermore, if you want to add a schedule function to your phone so that the same message is returned for all incoming calls, enter the number of the schedule event (for example, business trip, meeting, vacation, etc.) when registering the schedule. By configuring it to be the same as the corresponding message number, it is also possible to automatically set the message mode according to the schedule.

(5) As described in detail of the invention, 1. According to the present invention, if a message number is input in accordance with the telephone number on a digital telephone and the message mode is set, 2. When a call arrives, the calling ID is notified by the network. It compares the corresponding message number with the telephone number based on the message, transfers the corresponding message number and its telephone number to the processing node using the end-end data transfer function of the D channel, requests the message transmission, and has a database of messages. The processing node is configured to convert the message corresponding to the message number into dot pattern information, and similarly use the D channel's End-End transfer function to send a message containing a Kanji expression to the caller. . For this reason, there is no need for the digital telephone to be equipped with a ROM or input means and procedures for expressing messages in kanji characters, and it is also possible to change the message for every two callers, or to use it as an answering machine. Economical and highly convenient digital telephones and services can be realized. Moreover, since it is possible to transfer messages without responding to two incoming calls by using the end-to-end data transfer function of the D channel, there is no charge for one caller.
