The system comprises an input unit 6 for inputting an instruction by a user, and a display unit 7 for displaying character information, image information, voice information, and caller information during data communication.

The data communication terminal 8 has a communication means (not shown). If a call waiting signal is detected by the call waiting signal detection unit 3 during data communication, the communication control unit 4 transmits data (not shown) from the data communication unit 2 through the telephone station 1 so that data communication can be continued. A communication interruption request command is issued to the communication partner, and the caller number is displayed on the display unit 7. The user looks at the caller number, decides whether to speak with or ignore this party, and in the case of ignoring it, gives an instruction to ignore it from the input unit 6 to send a data communication restart command to the data communication partner. By transmitting, the caller ID can be displayed while continuing the data communication.

FIG. 2 is a circuit configuration diagram of the data communication terminal according to the first embodiment of the present invention. In FIG. 2, reference numeral 17 denotes a button key, which is means for a user to make a telephone call.

Reference numeral 14 denotes an LCD, which is a display unit for displaying a caller number, data communication characters, and image information;
This is a CallerID modem with Waiting signal detection, which is a means for detecting a call waiting signal and receiving a caller ID. Reference numeral 16 denotes a data modem, which is means for transmitting and receiving data. Reference numeral 11 denotes a CPU (Central Processing Unit), a ROM (Read Only Memory) 12 and a RAM
(Random access memory) 13 is read and executed. The RAM 13 is used to detect a call waiting signal even during data communication, determine that there is a possibility that transmission data from the other party may be lost at the central office by call waiting, and continue data communication. Communication control such as sending a data communication interruption request, a retransmission request, and a resumption request.

FIG. 3 is a flowchart showing an operation during data communication of the data communication terminal according to the first embodiment of the present invention. The operation will be described with reference to the flowchart of FIG.

The present invention is characterized by communication control during data communication, and other operations are similar to those of a normal telephone. Therefore, only operations during data communication will be described.

When data communication is started and the call waiting signal is being sent, the data sent by the data communication partner is:
Since the data communication partner does not arrive at this side and thinks that there is no response, there is a possibility that data communication will be disconnected, so set the maximum response time as necessary at the time of handshake (Steps 20, 21). When the data communication processing is completed (step 22), the same operation as that of a conventional telephone or data communication device is performed, and thus the description is omitted. If a call waiting signal is detected, a communication interruption command is sent to the data communication partner (steps 23 and 2).
4).

In response to a new incoming call, the caller's number received by the call-waiting-signal detector 3 is displayed on the display 7 so as to be ignored by the user or to temporarily make a call.
The data communication is terminated, and an operation selection such as a telephone call is prompted (step 25).

When the user instructs the input unit 6 to ignore the call, the new call is ignored, and the data communication partner is ignored.
A data communication restart command is sent, and the data communication process is continued until the user ends the data communication or there is a new incoming call (steps 26 and 27).

When the user temporarily instructs the input unit 6 to call, after terminating the call, a data communication restart command is sent to the data communication partner to continue the data communication (steps 28, 29, 30). .

When the user terminates the data communication and instructs the input unit 6 to make a call with a new incoming call, a communication end command is sent to the data communication partner, and the call is started (step 31).

Although the above description has been made on the assumption that the caller number is displayed, it is obvious that the present invention is also effective with a simple call waiting without displaying the number.

Furthermore, if the telephone number and the name, nickname, and the like are stored in the storage unit 5 of the data communication terminal 8 in association with each other, the corresponding caller number is displayed on the display unit 7 instead of being displayed. It is also possible to display a name, a nickname, and the like on the display unit 7.

As described above, according to the data communication system described in the first embodiment, a call waiting signal is received without disconnecting the data communication even during the data communication, and the user can respond to the call waiting signal. It becomes possible to select.

The display unit 7 can display the caller's telephone number by call weighting while looking at an Internet browser or the like.

Also, when the data communication terminal of the present invention detects a call waiting signal automatically and periodically when an electronic mail by data communication is automatically taken out, it rings a bell or the like to notify the user, The caller ID can be displayed, and even if the device uses a telephone line, the user does not need to be aware that the telephone line is occupied.

[0028]
