Description

[Detailed Description of the Invention] [Industrial Application Field J] The present invention relates to a communication device, and particularly to a communication device that transmits a paging signal including supplementary information from a calling device to a called device at the start of communication. It is.

[Prior Art] In the conventional analog public telephone network, when an incoming call is made, it is difficult to know the selected number of the caller, for example, the telephone number. This is because the network did not provide such a service, but since the call procedure of the recently launched L5DN network includes a service that notifies the caller ID, the called party The number can be recognized, and conventionally, the number notified by the calling party is used, for example, by displaying it on the display of the telephone.

[Problem to be Solved by the Invention 1] As mentioned above, conventionally, the only information available when receiving a call is the telephone number of the calling party, so the only benefit is that you can answer the call only when you want to receive the call. It was not possible to know for what purpose the call was made.

SUMMARY OF THE INVENTION An object of the present invention is to provide a communication device that allows the called party to recognize the business to some extent just by making a call.

[Means for Solving the Problems J] In order to solve the above problems, the present invention provides a communication device that transmits a paging signal including supplementary information from a calling device to a called device at the start of communication. , a means for manually inputting desired information as the supplementary information to the calling side device;
In addition, a means for outputting information transmitted as supplementary information of the calling signal to the called device in a predetermined output method is provided, and a transmitter for the calling signal is required on either the calling or called device. We adopted a configuration that includes a control means that prohibits line connections depending on the situation.

[Function 1] According to the above configuration, desired information can be transmitted as supplementary information to the paging signal sent from the calling side at the start of communication, and after sending and receiving this information, it is possible to transmit the desired information without making a line connection. Communication processing can be canceled immediately.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings. Figure 1 shows the structure of the receiving side device that adopts the present invention.
FIG. 2 also shows the structure of the transmitting side device according to the present invention. Here, it is assumed that each device is connected to a digital line such as an ISDN network, and is a telephone for making calls or a communication device for data communication.

The devices shown in FIG. 1 and FIG. 2 each include a communication control device and a terminal control device. In the called device shown in FIG. 1, the communication control device is composed of a data transmitting/receiving circuit 21i3 and an information detecting circuit 22 for transmitting and receiving signals to and from the digital line l. The data transmitting/receiving circuit 2I is composed of a digital modem, a voice processing circuit, etc., and a handset B for telephone calls is connected to the circuit. Also, the second
Also in the calling side device shown in the figure, the communication control I device 2 is constituted by the data transmitting/receiving circuit 23.

In the called side device shown in Fig. 1, the information detection circuit 2 is installed in the communication control device.
2 is provided, and this is a circuit that detects information transmitted from the other party's station according to the incoming call procedure of the digital line.
The detected information is input to the terminal control device 3.

The terminal control section 3 in FIG. 1 is composed of an information reading circuit 31 and a display control circuit 32. Information reading circuit 31
The 0 display control circuit 32 inputs predetermined data extracted by the information detection circuit 22, and inputs character information or image information thereof to the display control circuit 32. The 0 display control circuit 32 controls the display of the display device 4 such as a CRT display. The character code or binary image data input from the information reading circuit 31 is input to the display device 4 and visually displayed.

On the other hand, the terminal control device of the calling side device in FIG.

It is composed of a manual data reading circuit 34 and an information creation circuit 33. The input data reading circuit 34 reads data such as characters or images input from the input device 5. For example, if the human-powered device 5 is a character input device such as a keyboard, the input data reading circuit 34 generates a character code according to the input from the input device 5, and the information creation circuit 3
Enter 3.

Furthermore, if the human-powered device 5 is an image input device or the like,
The input data reading circuit 34 forms monovalued image data or further compressed image data according to the input, and inputs the data to the information creation circuit 33 . Information creation circuit 33
performs processing such as packetizing data into a form that can be transmitted and received over a digital line, or compressing redundancy, and its output signal can be transmitted to the digital line M1 via the data transmitting/receiving circuit 23.

Next, the operation of making a call from the calling device to the called device in FIG. 2 will be explained with reference to FIGS. 3(A) and 3(B). Third
Figure (A) shows the communication procedure of the calling side device in Figure 2, and Figure 3 (
B) shows a sequence of signals exchanged between calling and receiving devices via a network (ISDN network in this case).

In this embodiment, in one calling procedure, a paging signal is transmitted from the calling device to the called device via a network (for example, an I5DN network, etc., as shown by symbol a in FIG. 3(B)). 5ETUP signal, etc.) to send messages such as text and images.Normally, the ancillary information area of such a call signal has a data capacity of about 128 bytes. The area is used to transmit the telephone number (selected number) of the calling device.

This message is inputted from the input device 5 of FIG. 2, read by the input data reading circuit 34, converted into the format of a calling signal by the information creation circuit 33, and transmitted to the digital line l by the data transmitting/receiving circuit 23.

In step St in FIG. 3, a call command to determine whether the operator has input a call command is manually input by, for example, hooking off the handset B. At this time, the operator may be allowed to specify via an operation unit (not shown) whether only message transmission or normal communication is to be performed at the same time.

When a call is ordered, in step S2, the operator manually enters message information such as text or images to be transmitted in response to a call signal via the input device 5. Of course, a configuration may be provided in which message input is not performed for all communications by setting a mode switch or the like, or control is possible such that message input is not performed for that communication at all by operating a switch.

Subsequently, in step S3, the input data reading circuit 34 creates call data from the input data. At this time, the input data reading circuit 34 encodes characters (in the case of character information) and encodes them to suppress redundancy (in the case of image information, etc.)
is performed, and the output data is stored in the ancillary information area of the call signal by the information creation circuit 33. At this time, if the amount of information entered is larger than the capacity of the additional information area,
It is best to ignore the message itself, or ignore the extra human effort.

In step S4, FIG. 3 (
A paging signal is transmitted as shown in code a in B), and the other party is called.

In step S5, it is determined whether only message transmission is to be performed. This determination can be made by reading the operating state of a predetermined switch on the operating section. Further, this determination can also be made by identifying a flag or the like indicating the presence or absence of such a setting operation if such a setting operation is performed at the same time in step SL as described above.

If step S5 is affirmative, the line connection is cut off in step S6, and if negative, normal communication processing (call processing, etc.) is performed in step S7. C like the symbol C in figure (B)
If an 0NN signal is sent from the called side and no communication is to be performed, the called side sends a DISC signal as shown in code d, and then the connection is terminated by exchanging REL and RELC signals.

The calling signal transmitted from the calling device is received by the called device shown in FIG. In addition to performing known operations such as ringing, the information reading circuit 31 reads the contents of the ancillary information area of the calling signal, and the 1 display control circuit 32 converts it into information (such as bitmap data) that can be displayed on the display device 4. It is displayed on the display device 4.

Looking at this display, the operator on the called side can decide whether to accept the incoming call or not, and can also use the information sent as a message on the called side.

In particular, according to the above configuration, if the calling party disconnects the line after sending a message, or if the called party's operator rejects the incoming call, the line will not be connected and no charges will be made. It has the excellent effect of allowing simple messages to be sent and received at low communication costs.

In the above configuration, only the messages sent on the called side are displayed in sequence. For example, if messages are sent one after another while the operator is away, only the last message can be used. , these information may be stored using a configuration as shown in FIG.

FIG. 4 shows a transceiver type device in which the receiving and calling devices of FIGS. 1 and 2 are integrated.

Here, the communication control section 2 and the terminal control section 3, which have almost the same configuration in FIGS. 1 and 2, are shared.

The terminal control section 3 has an additional information creation circuit 33 composed of a semiconductor memory or a magnetic disk device, and both the display device 4 and the input device 5 are connected to the display control circuit 32 of the terminal control section 3, Human data reading circuit 3
4 is connected.

According to such a configuration, in the case of an incoming call, the message transmitted using the ringing signal is stored in the memory 39 according to the procedure shown in FIG.
The information stored in the memory 39 can be sequentially stored in the display device 4 in response to input from the input device 5.
can be displayed. Therefore, in addition to the effects of the above embodiments.

An excellent effect can be obtained in that all received messages can be effectively used.

In the display processing described above, messages stored in the memory 39 are displayed in order of oldest messages, or appropriate search processing is performed to display only messages containing only certain characters, symbols, or words. good.

In addition to displaying messages, it is also possible to connect a printer or the like to the device and record and output the information stored in the memory 39 as needed, or to display received messages without storing them in the memory 39. may be recorded and output.

In one or more of the embodiments shown in FIG. 5, characters,
An example has been shown in which information such as an image is transmitted as supplementary information of a calling signal, but here we will consider transmitting information about a ringing tone.

Conventionally, when a call is received from one line, the first called device sounds a pre-stored ring tone such as a bell tone to call the operator, and this ring tone cannot be changed. Therefore, the volume and tone of this ringtone,
It is impossible to control the melody etc. from the calling side, let alone the called side.

In the configuration shown in FIG. 5, the display control circuit 32 and display device 4 of the called device shown in FIG. The speaker 9 is made to sound based on the received data, and the ringing tone desired by the calling party is made to sound at the time of a call.

In this configuration, the message information transmitted as supplementary information of the calling signal may be, for example, digitally sampled audio data, and in this case, the transmitted digital audio signal is converted into audio data by the display control circuit 32 by D/A conversion. It is conceivable that the sound is restored and the speaker 9 is made to sound. In this case, the display control circuit 32 is a D/A
It consists of a conversion circuit, etc., and also a calling side device (Figure 2).
The input device 5 and the input data reading circuit 34 are composed of a microphone, an A/D conversion circuit, and the like.

The message information transmitted as supplementary information of the ringing signal is the drive data of the ringing circuit 38, for example, the driving data of the ringing circuit 38. When the speaker 9 is configured from a MIDI instrument, etc., data such as pitch, tempo, timbre, etc. may be used. In this case, the input device 5 of the calling side device (FIG. 2) is a keyboard device of a musical instrument, etc. Therefore, the input data reading circuit 34 is constituted by a MIDI data creation circuit or the like.

According to such a configuration, the operator on the called side can be called using the ring tone specified by the calling side.

This ringtone can enhance the sampled value as described above.

In the above, the message sent as additional information of the ringing signal was considered as a "ringing tone," but as in the previous embodiment, this is considered to be a voice message, and information that needs to be transmitted from the calling side to the called side. Needless to say, it can also be used for sending.

In the above, a telephone was considered as a communication device, but the present invention can of course be applied to a facsimile device that can send and receive supplementary information when making a call, and a data communication device. Of course, the input/output mechanism can be used to input and output messages sent and received as supplementary information. Furthermore, it goes without saying that the present invention can be applied to various communication networks, regardless of the type of communication network, as long as it is capable of transmitting and receiving supplementary information when making a call.

[Effects of the Invention] As is clear from the above, according to the present invention, in a communication device that transmits a paging signal including supplementary information from a calling side device to a called station side device at the start of communication, one calling side Providing means for manually inputting desired information as the supplementary information to the device, and means for outputting the information transmitted as the supplementary information of the calling signal to the called device in a predetermined output method,
Since a configuration is adopted in which either the calling side or the called side device is provided with a control means that prohibits line connection as necessary after the sending of the calling signal, the call signal is transmitted from the calling side at the start of communication. It is now possible to send desired information as supplementary information to a calling signal, and after sending and receiving this information, the communication process can be stopped without connecting a line, making it possible to send and receive messages in a predetermined format at low cost. Further, there is an excellent effect that the degree of freedom of information that can be transmitted and received as supplementary information is increased, and the added value of the device can be increased.
