Abstract

PURPOSE:To protect privacy, and to maintain security without executing any complicated operation by discriminating whether a caller is trustworthy or not, and transmitting automatically a self-portrait only in the case of the trustworthy caller. CONSTITUTION:At the time of call incoming, a CPU 12 incorporates a call incoming number out of a call setting message received by a communication control part 13, and discriminates whether the said call incoming number coincides with an automatic picture transmission number stored in a data storage part 18 or not, that is, whether the call incoming is to the automatic picture transmission number or not. As the result, when the call incoming is to the automatic picture transmission number, it controls a picture input part 15 so as to transmit automatically the self-portrait, and finishes the operation. On the other hand, when the said call incoming number coincides with a usual call incoming number stored in the data storage part 18, and the call incoming is to the usual call incoming number, it prevents the self-portrait from being transmitted. Namely, in the case of the call incoming to the automatic picture transmission number stored in the data storage part 18, the self-portrait is transmitted automatically, and in the case of the call incoming to the usual call incoming number, the self-portrait is not transmitted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videophone terminal having a function of transmitting not only voice information but also image information via a digital line.

[0002]

2. Description of the Related Art In a conventional analog telephone line, only a small amount of voice data can be transmitted, and the data transmission rate is relatively low.

However, in recent years, along with the progress of communication technology, semiconductor technology, and optical technology, a technology of digital transmission by a digital line has been developed, and a large amount of data can be transmitted at high speed without deteriorating the quality. Became. This digital transmission further has the advantage that the media can be integrated without requiring a transmission line according to the characteristics of the transmission data that differs depending on the type of media, and it has become possible to transmit data between the composite media terminals. Therefore, for example, videophone terminals that simultaneously transmit not only voice but also video have been realized.

In such a videophone terminal, it is desirable from the viewpoint of privacy protection, security, etc. to transmit the self-portrait only to a specific caller without unlimitedly transmitting the self-portrait on the receiving side.

Therefore, for example, Japanese Unexamined Patent Publication No. 4-265087
In the gazette, an image key is provided and a self-portrait is sent to the calling side only when the user presses this image key. And a mode for automatically transmitting.

[0006]

However, there are a large number of incoming calls from callers who may send the self-portrait, but in order to prevent the self-portrait from being sent when the caller who should not send the self-portrait receives the incoming call. In the case where the mode for transmitting the self-portrait by pressing the image key is set, it is necessary to press the image key for each incoming call from a caller who may frequently send a self-portrait, This pressing operation was troublesome.

On the other hand, when the mode for automatically transmitting the self-portrait at the time of incoming call is set, the annoyance of the operation of pressing the image key is released, but it becomes impossible to protect the privacy and the security. There was such a problem.

The present invention has been made under such circumstances, and an object thereof is to provide a videophone terminal capable of protecting privacy and security without transmitting the self-portrait in a troublesome operation. To provide.

[0009]

In order to achieve the above object, the videophone terminal according to the first invention has at least 2 terminals.
First storage means for storing the telephone numbers of the two self-terminals, and first determination means for determining whether or not the telephone number related to the incoming call is the specific telephone number stored in the first storage means. An image transmission is executed when the telephone number related to the incoming call is determined to be a specific telephone number by the first determining means, and an image transmission is prohibited when it is determined to be not a specific telephone number. And a transmission control means of.

In order to achieve the above object, the video telephone terminal according to the second aspect of the present invention stores a second storage means for storing personal identification data and a call setting message received at the time of an incoming call in the second storage means. Second discriminating means for discriminating whether or not the stored personal identification data is included, and it is discriminated by the second discriminating means that the personal identification data stored in the second storage means is included. Sends the image,
When it is determined that the personal identification data is not included, a second transmission control unit that prohibits image transmission is provided.

In order to achieve the above object, the videophone terminal according to the third aspect of the present invention has a third storage means for storing the telephone number of a communication partner desiring image transmission, and a telephone number for receiving an incoming call. When it is determined by the third determining means that determines whether or not it is stored in the storage means, and the telephone number related to the incoming call is determined to be stored in the third storage means by the third determining means, And a third transmission control means for prohibiting the image transmission when the image transmission is executed and it is determined that the image is not stored.

[0012]

In the first aspect of the invention, the first storage means stores the telephone numbers of at least two own terminals, and the first determination means stores the telephone number of the incoming call in the first storage means. It is determined whether or not it is the specified telephone number. And
The first transmission control means causes the image transmission to be executed when the telephone number related to the incoming call is determined to be the specific telephone number by the first determination means, and the image is transmitted when it is determined that the telephone number is not the specific telephone number. Prohibit sending.

Therefore, if the specific telephone number is given only to the reliable communication partner, the image is automatically transmitted to the incoming call from the reliable communication partner and to the incoming call from the other communication partner. Then, image transmission will not be performed.

In the second invention, the second storage means stores the password data, and the second determination means is stored in the second storage means in the call setting message received at the time of the incoming call. It is determined whether or not the personal identification data is included. Then, the second transmission control means performs the second determination by the second determination means.
When it is determined that the personal identification data stored in the storage means is included, image transmission is executed, and when it is determined that the personal identification data is not included, image transmission is prohibited.

Therefore, if the personal identification data is taught only to a reliable communication partner, an image is automatically transmitted when an incoming call is received from the reliable communication partner and an incoming image is received when another communication partner receives the incoming call. Image transmission will not be performed.

In the third invention, the third storage means stores the telephone number of the communication partner who desires image transmission, and the third determination means is that the telephone number relating to the incoming call is the third storage means. It is determined whether or not it is stored in. Then, the third transmission control means causes the image transmission to be executed when it is determined by the third determination means that the telephone number related to the incoming call is stored in the third storage means, and is not stored. When it is determined, the image transmission is prohibited.

Therefore, if only the telephone number of the reliable communication partner is stored in the third storage means, the image is automatically transmitted only to the incoming call from the reliable communication partner, and the other. The image transmission will not be performed for the incoming call from the other party.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, first to third embodiments of the present invention will be described with reference to FIGS.

[Arrangement of First to Third Embodiments] FIG. 1 is a block diagram showing a schematic arrangement of a videophone terminal according to the first to third embodiments of the present invention. The videophone terminal 11 shown in FIG.
The CPU 12 is a core for controlling transmission and reception of voice data and image data. The CPU 12 includes a line control unit 13, a code / demultiplex / multiplex / demultiplex unit 14, an image input unit 15, an image display unit 16, and a voice. The input / output unit 17 and the data storage unit 18 are connected.

Under the control of the CPU 12, the line control unit 13 controls the operation of transmitting / receiving voice data and image data to / from another videophone terminal or the like which should be performed via the ISDN network 19. The encoding / demultiplexing / multiplexing / demultiplexing unit 14 encodes and multiplexes the audio data and the image data in order to efficiently transmit the audio data and the image data via the ISDN network 19.
The encoded and multiplexed audio data and image data received via the SDN network 19 are separated and decoded.

The image input section 15 is used for the videophone terminal 11 of the present invention.
Input image data such as a video of the user. When transmitting the image data related to this input, the code / demultiplex / multiplex / demultiplexer 14 encodes / multiplexes and transmits as described above. The image display unit 16 displays the image data received and demultiplexed / decoded by the code / demultiplex / multiplex / demultiplex unit 14.

The voice input / output unit 17 inputs voice data and outputs the voice data received and demultiplexed / decoded by the code / demultiplex / multiplex / demultiplex unit 14. In addition, when transmitting voice data, code, decompress, multiplex,
The demultiplexing unit 14 encodes and multiplexes the data and transmits it. In the data storage unit 18, in addition to various programs for controlling transmission / reception of voice data, image data, and the like, information for determining whether or not image data may be automatically transmitted when an incoming call is received. I remember.

The information for determining whether or not the image data may be automatically transmitted at the time of an incoming call is the first information.
In the embodiment, two dial-in numbers assigned to the own terminal {normal incoming call number (telephone number for normal response) and automatic image transmission number (telephone number for automatic image transmission)} are stored,
In the second embodiment, personal identification data is stored, and in the third embodiment, the dial-in number of the communication partner to whom the image data may be automatically sent upon receiving a call is stored.

Further, when communication is performed via the ISDN network, the call setting message for notifying the incoming call to the other terminal is
CCITT Recommendation Q.3 as shown in FIG. It is created according to the format of the call setup message 200 defined in 931. That is, this call setup message 200 is
Protocol identifier 201, call number 202, message type 203, transmission capability 204, channel identifier 205, facility 206, progress identifier 207, display 208, keypad facility 209, signal 210, feature activation 211, feature indication 212, calling number. (Calling number) 213, Calling sub address 214, Called number (Called number) 215, Called sub address 216, Relay network selection 217, Low layer compatibility 21
8, high layer compatibility 219, user / user information 22
It is composed of 0s. In the first, second, and third embodiments, as will be described later, the incoming call number 21
5, user / user information 220, and calling number 213 play a major role.

[Operation of the First Embodiment] Next, the image data automatic transmission operation at the time of an incoming call according to the first embodiment will be described with reference to the flowchart of FIG.

When receiving a call, the CPU 1 controls the line control unit 13
The incoming call number 215 is taken in from the above call setting message received at (step S31). And
It is determined whether or not the incoming call number matches the image automatic transmission number stored in the data storage unit 18, that is, whether or not the incoming call is to the image automatic transmission number (step S3).
2).

As a result, if there is an incoming call to the image automatic transmission number, the image input unit 15 is controlled to automatically transmit the self image (step S33), and the process ends. On the other hand, if the incoming call number 215 matches the normal incoming call number stored in the data storage unit 18 and the incoming call is to the normal incoming call number, step S33 is skipped and the self-portrait is not transmitted. .

As described above, in the case of an incoming call to the image automatic transmission number stored in the data storage section 18, the self-portrait is automatically transmitted, and in the case of an incoming call to the normal incoming call number,
Since the self-portrait is not transmitted, if the automatic image transmission number is given only to a reliable person, the self-portrait can be automatically transmitted only to the reliable person without performing a troublesome operation.

[Application Modification of First Embodiment] Whether or not the incoming call is to the telephone number for automatic image transmission is determined by the destination subaddress 216 in the call setup message in the ISDN network, not by the dial-in number. It is also possible to do so. In this case, subaddress numbers may be preset in the data storage unit 18 instead of dial-in numbers. By using the sub-address number in this way, it is not necessary to obtain the dial-in number.

[Second Embodiment] I used in the second embodiment
The format of the user / user 220 in the call setup message in the SDN network is as shown in FIG. That is, a 7-bit user / user 220 indicating that it is the user / user information in the call setup message.
a, data length 220b of data content (user information 220d) in user / user information, protocol identifier (user-specific protocol) 220c, user information 220
It is composed of d. Then, the personal identification data as information for determining whether or not the image data may be automatically transmitted at the time of the incoming call is transmitted as the user information 220d.

Next, the image data automatic transmission operation at the time of an incoming call according to the second embodiment will be described with reference to the flowchart of FIG.

When receiving a call, the CPU 1 controls the line control unit 13
In the above call setup message received at
It is determined whether or not the UI (user / user information 220) is included (step S51). As a result, the user
If the user information 220 is included, the personal identification data as the user information 220d is extracted from the user / user information 220 (step S52), and the data storage unit 18 is extracted.
It is determined whether or not it matches the personal identification data stored in (step S53).

As a result, if they match, the image input unit 1
5 to automatically transmit the self-portrait (step S
54) and ends. On the other hand, if the two pieces of secret identification data do not match, step S54 is skipped and the process ends, thereby preventing the self-portrait from being transmitted. Note that step S
When it is determined in 51 that the user / user information 220 is not included, the process ends without performing anything.

As described above, since the self-portrait is automatically transmitted only when the personal identification data stored in the data storage unit 18 and the personal identification data relating to the reception coincide with each other, the personal identification data is transmitted only to a reliable partner. If you tell me, you will be able to automatically send self-portraits only to trusted parties without tedious operations.

[Operation of the Third Embodiment] Next, the image data automatic transmission operation at the time of an incoming call according to the third embodiment will be described with reference to the flowchart of FIG.

When receiving a call, the CPU 1 controls the line control unit 13
The calling number 213 is fetched from the above call setting messages received in step S61 (step S61). And
It is determined whether or not the calling number is stored in the data storage unit 18 as the dial-in number of the communication partner to which the image data may be automatically transmitted upon receiving a call (step S).
62).

As a result, if the calling number is stored,
The image input unit 15 is controlled to automatically transmit the self-portrait (step S63), and the process ends. On the other hand, if the calling number is not stored, the process skips step S63 and ends so that the self-portrait is not transmitted.

As described above, since the self-portrait is automatically transmitted only when the calling number is stored as the dial-in number of the communication partner to which the image data may be automatically transmitted at the time of incoming, it is reliable. By storing only the dial-in number of the communication partner, it becomes possible to automatically transmit the self-portrait only to the reliable partner without performing a troublesome operation.

The present invention is not limited to the above embodiments, but can be applied to, for example, a videophone terminal transmitting a large amount of image data via a digital communication network other than the ISDN network. Is.

[0040]

As described above, according to the video telephone terminal of the present invention, it is determined whether or not the sender is a reliable sender, and the self-portrait is automatically transmitted only when the sender is a reliable sender. Therefore, it is possible to protect the privacy and the security without sending the self-portrait when the self-portrait is transmitted.
