DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information terminal device having a telephone function, and more particularly to an information terminal device capable of selecting a caller based on a keyword and making a call, and a call control method.

[0002]

2. Description of the Related Art Conventionally, a general telephone device adopts a method of making a call by inputting a telephone number of a partner when making a call. Then, if necessary, the user inputs the extension number and the like. When the receiver knows that the call has been received by a ring tone or the like, the receiver presses an incoming call button or the like to talk with the caller. At that time, it is general that it is not clear from whom the call is made by actually answering the phone and not talking to the other party.

Therefore, one of the recently introduced telephone services is
One has a caller ID display function. This is called "number display (registered trademark)" and is a service for displaying the telephone number of the caller on the display of the receiver at the time of an incoming call. Thus, the recipient can know who the other party is from the telephone number before answering the call.

[0004]

However, even if the receiver has a telephone device compatible with the number display, the display of the telephone number is prohibited by the caller, or the caller is not allowed to display the telephone number. When a telephone call is made using the telephone device, there is a problem that the recipient cannot identify the other party. For this reason, there has been a problem that an unspecified number of people receive a call, and a nuisance call such as a wrong call or a prank call has to be received.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide an information terminal device and a call control method that allow only a call from a partner permitted by a receiver at the time of an incoming call.

[0006]

SUMMARY OF THE INVENTION The present invention relates to an information terminal device used in a telephone system capable of transmitting keyword data after inputting a telephone number, wherein the keyword data transmitted from a caller at the time of an incoming call is provided. Is received, the received keyword data is compared with the pre-registered keyword data. If the keyword data of both the received data matches, it is determined that the recipient is a partner authorized by the receiver, and This establishes a call with the user.

[0007] According to such a configuration, at the time of an incoming call, it is determined whether or not the recipient is a permitted party based on the keyword attached to the telephone number, and a call is established only when the recipient is the permitted party. You. Therefore, it is possible to prohibit a call from a party who does not know the keyword, that is, a party who does not permit the keyword, before calling.

Various programs downloaded from the external storage device 17 are stored in the program area 13d. Here, a speech recognition program for recognizing speech data is also included.

The mode storage area 13e stores state data of the call establishment mode arbitrarily set by the user. The call establishment mode is a mode for forcibly establishing a call with a caller, and is made up of, for example, 1-bit data.
At the time of establishment indicates the established state. In the non-established state, a call with the caller is not established when the keyword determination results do not match. In the established state, the call with the caller is forcibly established even if the keyword determination results do not match.

Next, the operation of the embodiment will be described.

(Transmission Processing) First, the transmission processing by the sender will be described with reference to FIG. FIG. 3 is a flowchart showing the operation of the calling process by the caller.

In general, a method is adopted in which a caller inputs a telephone number of a call partner and makes a call. In this embodiment, the caller inputs the telephone number of the call partner (step A11), attaches the keyword of the call partner obtained in advance (step A12), and transmits the call to the call partner (step A13). Make a call using the following procedure.

In this case, if the keyword is voice data, after inputting the telephone number, the sender inputs a predetermined word determined by the other party through the transmitter. When the present apparatus is used as a transmitting device, the voice input unit 16 shown in FIG.
Will be used to input a voice keyword.

If the keyword is image data,
After inputting the telephone number, a predetermined image determined by the other party is input using a video camera or a scanner. If the sender does not have an image input unit such as a video camera or a scanner, the image may be stored in a file and communicated by data. When this apparatus is used as a transmission device, an image keyword is input using the image input unit 15 shown in FIG.

If the keyword is dial number data, after inputting the telephone number, a predetermined dial number determined by the other party is input through the same input means as the telephone number. When this apparatus is used as a transmission device, a dialing keyword is input using the key input unit 14 shown in FIG.

(Reception Processing) Next, the reception processing by the receiver will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the receiving process by the receiver.

When the communication control unit 20 provided in the apparatus receives a call from the caller side when the apparatus is used as a receiving device (step B11), the control unit 11
First checks whether a keyword is attached to the telephone number transmitted by the caller (step B1).
2). As a result, when the keyword is not attached (No in step B12), the control unit 11 determines that the recipient is not a partner permitted by the receiver, and does not emit a ringtone or the like, and transmits the caller through the communication control unit 20. Is disconnected (step B17). At this time, a voice message such as “There is no keyword. Please enter a keyword and try again” may be sent to the sender.

If the keyword is attached (Yes in step B12), the control unit 11 performs a comparison process between the keyword and the keyword held by the receiver (step B13). In the present embodiment, since voice, images, and dials can be used as media used for keywords, when performing keyword comparison processing, the type of keyword is checked and registered in the device in advance according to the type. Processing such as reading out the same type of keyword that has been performed is required. These processing will be described later with reference to FIG.

If the received keyword does not match the registered keyword, that is, if the keyword sent from the sender is incorrect (N in step B14)
o), the control unit 11 determines that the receiver is not the partner permitted, and disconnects the telephone line with the caller through the communication control unit 20 without emitting a ringtone or the like (step B17). At this time, a voice message such as "The keyword is wrong. Please enter the correct keyword and try again" may be sent to the sender.

On the other hand, if the received keyword matches the registered keyword, that is, if the keyword sent from the sender is correct (Yes in step B14)
s) The control unit 11 determines that the recipient is a partner permitted by the receiver, sounds a ringtone, and establishes a call with the partner (step B15). As a result, the user can make a telephone call with the caller through the telephone line by pressing the incoming call button or lifting the receiver (step B16). After the call, the line with the caller is disconnected (step B17).

As described above, it is determined whether or not the recipient is a permitted party based on the keyword attached to the telephone number, and a call is established only when the recipient is a permitted party. Therefore, the person who does not know the keyword, that is,
Calls from parties that the recipient does not allow can be prohibited before calling.

In the above embodiment, no call is received from a partner who does not know the keyword, and there are some problems. Therefore, as an option, a call establishment mode that can be arbitrarily set by the user is provided,
A configuration may be adopted in which a call with the caller is forcibly established according to the state of the call establishment mode (established state / non-established state). FIG. 5 shows the processing operation in this case.

FIG. 5 is a flowchart showing the operation of the receiving process when the call establishment mode is provided. In FIG. 5, the processes in steps B11 to B17 are the same as those in FIG. 4, and therefore, only the differences (the processes in steps B18 and B19) will be described.

That is, when there is no keyword from the sender (No in step B12), or when there is a keyword but the keyword is not correct (No in step B14), the control unit 11 sets the RAM 13
The state data of the call establishment mode stored in the mode storage area 13e is checked (step B18). In addition,
The user can arbitrarily set the call establishment mode, and the set contents (established state / non-established state) at that time are held in the mode storage area 13e as the state data of the call establishment mode.

Here, when the call establishment mode is set to the established state (Yes in step B19), the control unit 11 performs a process for establishing a call with the caller regardless of the keyword determination result ( Step B15). on the other hand,
When the call establishment mode is set to the non-establishment state (Yes in step B19), the control unit 11 performs a process of disabling the call with the caller based on the keyword determination result and disconnecting the line. Perform (Step B1
7).

As described above, if the call establishment mode is set to the established state as needed, a call from a partner who does not know the keyword can be received.

(Keyword Comparison Processing) Next, the keyword comparison processing executed in step B13 will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the keyword comparison process.

When a keyword is sent from the sender, the control unit 11 determines the type of the keyword (step C11). As a result, if the keyword is voice data, the control unit 11 activates a voice recognition program stored in the program area 13d of the RAM 13, performs voice recognition processing on the voice data, and recognizes a word spoken by the caller. Acquire (Step C12). Next, the control unit 11 reads the keyword data for voice from the keyword storage area 13a of the RAM 13 as a registered word (step C13), and compares the registered word with a received word obtained as a result of voice recognition (step C14). In this case, it is checked whether or not the code data of each character constituting both words is the same.

If the keyword is image data, the control unit 11 stores the keyword in the keyword storage area 13 of the RAM 13.
Image keyword data is read out from b as a registered image (step C15), and the registered image is compared with the received image (step C16). In this case, for example, if the image data is a still image, it is checked whether or not the still image (the image in which a specific mark or the like is read) is the same as the registered image. If the image data is a moving image, one frame of the moving image (an image of the sender's face or the like) is extracted, and it is checked whether the image is the same as the registered image.

If the keyword is dial number data, the control section 11 reads out the dialing keyword data from the keyword storage area 13c of the RAM 13 as a registration number (step C17), and compares the registration number with the reception number. (Step C18). In this case, it is checked whether or not a predetermined number of dial numbers (reciter numbers) input by the caller are the same as the registered numbers.

As described above, according to the type of the keyword,
The same type of keywords registered in the apparatus are read out as appropriate and compared with the keywords sent from the sender.

(Keyword Change Processing) Next, the keyword change processing by the receiver will be described with reference to FIG. FIG. 7 is a flowchart showing the operation of the keyword change process by the recipient.

When the recipient changes the keyword, the user first selects the type of keyword to be changed (step D11). When a voice is selected, a word serving as a new keyword is voice-input using the voice input unit 16 including a microphone or the like (step D12). When voice data is input, the control unit 11
Activates a voice recognition program stored in the program area 13d of the RAM 13, performs voice recognition processing on the voice data (step D13), and uses the word (character code) obtained as a result of the recognition as voice keyword data as RA.
It is stored in the keyword storage area 13a of M13 (step D14).

When an image is selected as the keyword type, the user uses the image input unit 15 including a video camera, a scanner, or the like to photograph an image (moving image / still image) serving as a new keyword (step). D15).
When the image data is input, the control unit 11 stores the image data in the keyword storage area 13b of the RAM 13 as image keyword data (step D16).

When a dial number is selected as the keyword type, the user directly inputs a dial number as a new keyword by using the key input unit 14 including a keyboard, a pen, a dial, and the like (step D).
17). When dial number data is input, the control unit 1
1 stores the dial number data as keyword data for dialing in the keyword storage area 13c of the RAM 13 (step D18).

When there is an instruction from the user to terminate the keyword setting (Yes in step D19), the control section 11 terminates the processing here.

As described above, when a keyword is changed, a new keyword is inputted and registered using a device corresponding to the type of the keyword to be changed.

(Keyword Notification Processing) Next, the keyword notification processing by the receiver will be described with reference to FIG. FIG. 8 is a flowchart showing the operation of the keyword notification processing by the receiving side.

When notifying the caller of the keyword from the receiver, the user first selects the type of the keyword to be notified (step E11). When the user selects the voice, the control unit 11 reads the keyword data for voice from the keyword storage area 13a of the RAM 13 (step E12). Then, in accordance with the transmission instruction (Yes in step E15), the control unit 11 activates the communication control unit 20 and transmits the above-described voice keyword data to the other party (step E16).

Similarly, when the user selects an image, the control unit 11
b, the image keyword data is read out (step E).
13) In accordance with the transmission instruction (Ye in step E18)
s) The image keyword data is transmitted to the other party through the communication control unit 20 (step E16). Also,
When the user selects the dial, the control unit 11
The dialing keyword data is read from the keyword storage area 13c of the AM 13 (step E14), and in accordance with the transmission instruction (Yes in step E18), the communication control unit 2
0, the keyword data for dialing is transmitted to the other party (step E16).

As described above, when notifying a keyword, a registered keyword is read out according to the type of the keyword to be notified, and is transmitted to the other party. On the transmitting side, the keyword acquired by the receiver side is acquired by this notification, and can be used when making a call. In this case, the password used in personal computer communication or the like is identification information unique to the sender, and anyone who has the password can perform communication without permission. Only those who know the keyword can call the recipient and make a call. In other words, it is possible to make a call only with the party permitted by the receiver (ie, the party who has notified the keyword).

In the above embodiment, when voice is used as a keyword, the voice data of the user is subjected to voice recognition processing, and the character code based on the recognition result is registered. However, the voice data is registered as it is. (recording)
In addition, when comparing with the keyword of the caller at the time of the incoming call, the voice data of both may be subjected to voice recognition processing and then compared.

When voice is used, for example, voice data for each user is registered, and the voice data transmitted from the caller is analyzed, and the analysis result is used. A configuration for establishing a call with the caller in response is also possible.

The same applies to the case where an image is used.
For example, the image data of the face for each user is registered, the face of the image data sent from the caller is analyzed, and a call with the caller is established according to the analysis result. Such a configuration is also possible.

Further, in the above-described embodiment, after judging whether or not the recipient is the permitted party based on the keyword attached to the telephone number, the communication is established only when the recipient is the permitted party. However, a system is also possible in which a telephone call is first established with a partner, and then the partner is determined based on a keyword sent from the sender.

In such a system, for example, when an incoming call is received by using the answering machine function, a call with the other party is established and connected to the answering machine. Please send a voice message such as "Please," and determine the other party based on the response result.

That is, if a predetermined keyword is sent from the sender side, it is determined that the recipient is a partner permitted by the receiver, and if the predetermined keyword is not sent from the sender side, the receiver permits. Judge that you are not the other party. If the recipient is a permitted partner, the user (recipient) is notified of that by voice, screen display, LED lighting, or the like. By this notification, the user can talk with the other party by lifting the receiver or the like. On the other hand, if the recipient is not a permitted partner, the user is notified and takes measures such as cutting off the line with the partner. As a result, it is not necessary to receive a nuisance call directly.

Note that the method described in the above-described embodiment includes, as programs that can be executed by a computer, for example, a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM,
It is also possible to write the data on a recording medium such as a DVD or a semiconductor memory and apply it to various devices, or to transmit it via a communication medium and apply it to various devices. A computer that realizes the present apparatus reads the program recorded on the recording medium, and executes the above-described processing by controlling the operation of the program.

[0058]

As described above, according to the present invention, in a telephone system capable of transmitting keyword data after inputting a telephone number, keyword data transmitted from a caller at the time of an incoming call is received and received. A call with the caller is established according to the comparison result between the keyword data and the pre-registered keyword data, so that calls from parties who do not know the keyword are prohibited, and incorrect calls, prank calls, etc. Can prevent unwanted calls.
