Description

The present invention relates to a communication terminal, a control method, and a program.

In recent years, nuisance calls aimed at wire transfer fraud and malicious solicitation have become a major social problem. In order to prevent nuisance calls, the phone number used for the nuisance call (nuisance phone number) is registered in the memory of the user's phone, and the next time a call is received from the same nuisance phone number,
Telephones equipped with a "nuisance call rejection function" that automatically accepts or rejects incoming calls are known (for example, see Patent Document 1)

Japanese Patent Application Publication No. 2003-134218

However, once a user responds to a nuisance call, the person on the other end may persistently offer to purchase expensive products, making it difficult for the user to refuse the fraudulent solicitation. There was a risk of being involved in a crime.

It may be TE (Long Term Evolution), CDMA (Code Division Multiple Access), other communication lines, or a combination thereof. Further, the network N may be wired or wireless. Further, the network N is not limited to the above example as long as communication between the server device 100 and the communication terminal 200 is possible.

The server device (management device) 100 may be configured by, for example, a dedicated or general-purpose information processing device. The server device 100 may provide information regarding nuisance calls (nuisance call information) to the communication terminal 200 via the network N. The nuisance call information may include, for example, the telephone number of the nuisance call, the name of the person making the nuisance call, and the name of the company making the nuisance call.
First, the server device 100 may collect nuisance call information provided from external organizations such as the police and local governments, and from each user. Specifically, the server device 100 may collect, for example, the telephone numbers of nuisance calls. The server device 100 may create a nuisance phone number list L1 based on the collected nuisance call information. The server device 100 may distribute the nuisance phone number list L1 to the communication terminal 200. The communication terminal 200 periodically or irregularly updates the nuisance phone number list L.
1 acquisition request may be sent to the server device 100. The server device 100 is a communication terminal 200
The nuisance phone number list L1 may be distributed to the communication terminal 200 in response to a request to obtain the nuisance phone number list L1 from the user. Note that the server device 100 periodically or irregularly sends the latest nuisance phone number list L1 to the communication terminal 20 without receiving a request to obtain the nuisance phone number list L1.
You may also push distribution to 0. Further, the server device 100 may be configured by a single information processing device, or may be configured by a plurality of information processing devices distributed on a network. Further, the server device 100 may periodically or irregularly acquire nuisance call information and update the nuisance phone number list L1. For example, the server device 100 may distribute the latest nuisance phone number list L1 to the communication terminal 200. Also, nuisance phone number list L
1 may be a data set that includes at least data on telephone numbers of nuisance calls. That is, the nuisance telephone number list L1 may be configured with any data structure.

Communication terminal 200 is a terminal owned by a user. The communication terminal 200 may be configured by, for example, a mobile phone, a smartphone, a tablet terminal, a wearable terminal, or the like. The communication terminal 200 can communicate with a terminal at the other end of the call (hereinafter also referred to as "another terminal") via a telephone line network or the like. The other party's terminal (first terminal) may be any terminal capable of making a telephone call via a telephone network, such as a mobile phone or a smartphone.

FIG. 2 is a block diagram illustrating an example of the configuration of main parts of the communication terminal 200.
The communication terminal 200 may include a control section 201 , a communication section 204 , a storage section 205 , a reception section 206 , a transmission section 207 , an operation reception section 208 , and a display section 209 . The control unit 201 is a CPU
202 and a memory 203. Note that FIG. 2 merely shows the main configuration of the communication terminal 200. That is, the communication terminal 200 may include other configurations included in a general information processing device as appropriate.

The control section 201 may centrally control each section of the communication terminal 200. The CPU 202 may implement the functions of the communication terminal 200 by loading various programs stored in the storage unit 205 and the like into the memory 203 and executing them. Details of the processing executed by the control unit 201 will be described later.

The communication unit 204 may be a communication interface for communicating with the server device 100, a partner terminal, etc. via the network N. As an example, the communication unit 204 may communicate with the server device 100.
A request to obtain the latest nuisance phone number list L1 may be sent to. Further, the communication unit 204 may receive, for example, the nuisance phone number list L1 in response to the acquisition request from the server device 100.
The nuisance phone number list L1 received by the communication terminal 200 is stored in the storage unit 20 by the control unit 201.
5 may be stored. For example, each time the control unit 201 receives the latest nuisance phone number list from the server device 100, the control unit 201 may update the nuisance phone number list already stored in the storage unit 205 to the latest nuisance phone number list. Further, the communication unit 204 may transmit and receive various signals related to a call (such as a calling signal, a calling signal, a response signal, and a disconnection signal) to and from the other party's terminal.

The storage unit 205 may be configured by a storage device such as a semiconductor storage device or a hard disk. The storage unit 205 may store various programs and various data. For example, storage unit 2
05 may store the nuisance phone number list L1 received from the server device 100. Also,
The storage unit 205 may store, for example, a nuisance call countermeasure application (hereinafter also referred to as "nuisance call countermeasure application") AP1 that can detect a nuisance call when making or receiving a call, and output a warning message. . Furthermore, the storage unit 205 may store, for example, guide voice data D1 for countermeasures against nuisance calls.

The nuisance call countermeasure application AP1 may be a so-called resident application. That is, the nuisance call countermeasure application AP1 may be automatically executed in the background at all times while the communication terminal 200 is operating. The guide audio data D1 for countermeasures against nuisance calls may be data for generating a voice message (guide voice for countermeasures against nuisance calls) for the purpose of deterring nuisance calls. The guide voice for countermeasures against nuisance calls is output not only to the user's communication terminal 200 but also to the other party's terminal when responding to an incoming nuisance call, but this point will be described later.

The receiver 206 may be configured with any device capable of outputting sound, such as a speaker. The receiver unit 206 may output various sounds based on the voice of the other party received via the communication unit 204 and data related to sound effects stored in the storage unit 205. Receiving unit 206
The functions may be controlled by the control unit 201.

The transmitter 207 may be configured with any device capable of converting input sound into an electrical signal, such as a microphone. The voice transmission unit 207 may receive input of the user's voice during a call with the other party's terminal. The functions of the transmitter 207 may be controlled by the controller 201.

The operation reception unit 208 may be configured by any device capable of inputting various information, such as a touch panel or operation keys. The operation reception unit 208 may accept various operation inputs from the user and send control signals corresponding to the operation inputs to the control unit 201. The functions of the operation reception unit 208 may be controlled by the control unit 201.

The display unit 209 may be configured by any device capable of displaying various information, such as a display. The display unit 209 may output and display an image based on the image data stored in the storage unit 205. The functions of the display section 209 may be controlled by the control section 201.

Next, a description will be given of an automatic nuisance call recording function realized by the control unit 201 executing the nuisance call countermeasure application AP1.

<Automatic recording function for nuisance calls>
FIG. 3 is a sequence diagram for explaining an example of an automatic recording function for nuisance calls.
The control unit 201 of the communication terminal 200 may receive a signal representing a call request (that is, an incoming call) from the other party's terminal via the network N, and may detect that there is an incoming call (step S1). Then, the control unit 201 may determine whether the incoming call from the other party's terminal is a nuisance call (step S2).

Specifically, for example, the control unit 201 compares the telephone number of the other party's terminal included in the call request, etc. with the nuisance telephone number list L1 stored in the storage unit 205, thereby detecting a call from the other party's terminal. It may be determined whether the incoming call is a nuisance call or not.

The control unit 201 may determine that the incoming call from the other party's terminal is a nuisance call when the telephone number of the other party's terminal matches any nuisance telephone number in the nuisance telephone number list L1. (
Step S2: YES) Furthermore, the control unit 201 may determine that the incoming call from the other party's terminal is not a nuisance call if it does not match any of the nuisance phone numbers in the nuisance call number list L1 (Step S2: NO).

The control unit 201 may start normal call processing if the incoming call from the other party's terminal is not a nuisance call (step S3).
When the incoming call from the other party's terminal is a nuisance call, the control unit 201 displays an incoming call screen on the user's communication terminal 200 that includes a warning message informing the user that the incoming call is from a nuisance call.
may be displayed on the display unit 209 (step S4).

FIG. 4 is a diagram illustrating an example of the incoming call screen G1 displayed on the display unit 209.
On the incoming call screen G1, for example, a warning message M1 that notifies the user that the call is an incoming call from a nuisance call, and a warning icon I1 that allows the user to instantly recognize that the call is a nuisance call may be displayed at the top. In addition, on the incoming call screen G1, for example, the phone number of the nuisance call is displayed from the middle to the bottom, a response permission button B1 for responding to the incoming nuisance call, and an answer permission button B2 for not responding to the nuisance call, etc. are displayed. It's okay to be. After confirming the nuisance telephone number etc., the user may select and operate either the response permission button B1 or the response permission/denial button B2. Note that the messages and icons displayed on the incoming call screen G1 may be arbitrarily arranged on the screen and are not limited to the above example.

Returning to the explanation of FIG. 3. The control unit 201 may determine whether the user has answered or rejected the nuisance call based on the user's selection operation of the response permission button B1 or the response permission/denial button B2 (step S5). When the control unit 201 detects that the response permission button B2 has been selected via the operation reception unit 208, the control unit 201 may disconnect the incoming call from the other party's terminal (step S6) and terminate the process. In this case, the control unit 201 may disconnect the incoming call after transmitting an acceptance/rejection message such as "Calls from this telephone number are not accepted" to the other party's terminal.

On the other hand, when the control unit 201 detects that the response permission button B1 has been selected via the operation reception unit 208, it returns a response signal etc. to the other party's terminal and establishes a connection between the communication terminal 200 and the other party's terminal. (step S7), and then the call may be started.

The control unit 201 may read the guide audio data D1 for countermeasures against nuisance calls from the storage unit 205 when a call with the other party's terminal is started. The control unit 201 may generate a guide voice based on the read guide voice data D1 for preventing nuisance calls. The guide voice may be a voice that conveys a message such as, for example, "This call will be recorded to prevent nuisance calls. This guidance is also being played back to the person on the other end of the call...". Note that the content of the message transmitted by the guide voice is not particularly limited as long as it can convey to the user and the other party that some kind of processing will be performed in response to an incoming call from a nuisance call. That is, the content of the message is not particularly limited as long as the guide voice can prevent criminal acts such as fraud or nuisance acts by the other party. Further, the control unit 201 may read the guide voice data D1 for countermeasures against nuisance calls from the storage unit 205 at the same time as the start of the call. here,
The term "simultaneously" may include some errors as long as the function of the present invention is not impaired.

After generating the guide voice, the control unit 201 may set predetermined functional restrictions on the receiving unit 206 and the transmitting unit 207 (step S8). After that, the control unit 201 may output the generated guide voice from the receiver unit 206 (step S9). Furthermore, the control unit 201 may transmit the guide voice to the other party's terminal via the communication unit 204 (step S10). Note that the control unit 201 may transmit the guide voice to the other party's terminal via the communication unit 204 in the same sequence as when the user inputs voice to the transmitting unit 207. That is, the control unit 201 may transmit the guide voice to the other party's terminal via the communication unit 204 in the same format as the voice input by the user to the transmission unit 207 . Therefore, the other party's terminal can recognize the guide voice as voice uttered by the user and output it from a speaker or the like. Note that, in the present disclosure, among the signals transmitted from the communication terminal 200 to the other party's terminal, a signal that can be output as sound from a speaker or the like of the other party's terminal may be referred to as a speech signal.

FIG. 5 is a diagram illustrating an example of functional limitations set to the receiver section 206 and the transmitter section 207.
While the generated guide voice is being output from the receiver unit 206 (hereinafter referred to as “
Also referred to as "guide audio output period." ), outputs only the guide audio and outputs audio other than the guide audio (
For example, a functional restriction may be set on the receiver unit 206 to turn off the output of the other party's voice (see A in FIG. 5). That is, in the guide audio output period, the control unit 201
The receiver 206 may be controlled so that the user hears only the guide voice.

Further, the control unit 201 may set a functional restriction on the transmitting unit 207 such as turning off the audio input (that is, turning off the function of the transmitting unit 207) during the guide audio output period (B in FIG. 5).
reference). That is, the control unit 201 may control the transmitting unit 207 so that the user's voice does not reach the other party during the guide voice output period.

As described above, according to one embodiment of the present invention, the guide voice can be output not only from the user's communication terminal 200 but also from the other party's terminal. Therefore, according to an embodiment of the present invention, it is possible to alert the user himself/herself to nuisance calls, and also to prevent the other party from committing criminal acts or acts of nuisance. In other words, when a user responds to an incoming nuisance call, it is possible to suppress damage caused by criminal acts or nuisance acts. In addition, even if the other party is speaking during the guide voice output period, the content of the utterance may be lost to the receiver.
It will not be output from 06. Furthermore, even if the user himself/herself utters something during the guide voice output period, the content of the utterance is input to the speech transmitter 207, and the content of the utterance is not output from the other party's terminal. Therefore, according to an embodiment of the present invention, when a user answers an incoming nuisance call, the user and the other party cannot immediately converse. In other words, it is possible to reduce the possibility that a conversation will start between the user and the other party, and that the user will be repeatedly victimized.

Returning to the explanation of FIG. 3. The control unit 201, in the user's communication terminal 200 and the other party's terminal,
When it is detected that the output of the guide voice has ended, the functional restrictions set on the receiver section 206 and the transmitter section 207 may be canceled (step S11). That is, the control unit 201 may turn on all functions of the receiver unit 206 and the transmitter unit 207 upon completion of outputting the guide voice, thereby enabling the user to talk with the other party. As a result, even if the call is mistakenly determined to be a nuisance call, the user can start a conversation with the other party.

When the call starts, the control unit 201 may start recording the call (step S12). Specifically, the control unit 201 stores the voice of the other party receiving the call via the communication unit 204 and the user's voice input from the transmitting unit 207 as voice call data in the storage unit 2.
It may be stored in 05. Note that the control unit 201 may start recording at the same time as the start of the call. Here, "simultaneously" may include some errors as long as the function of the present invention is not impaired.

Thereafter, when the user presses a call end button (not shown) or the like and inputs an instruction to end the call, the control unit 201 may end the recording of the call (step S13). Then, the control unit 201 may transmit a disconnection signal or the like via the communication unit 204 to release the connection (step S14), and end the process described above.

In summary, according to one embodiment of the present invention, when a nuisance call is received and a call is initiated in response to the nuisance call, both the other party and the user are notified of the nuisance call. A guide voice is output for the purpose of preventing calls, and then recording of the call automatically starts. Thereby, even if a call is started in response to an incoming nuisance call, damage caused by the nuisance call can be effectively suppressed.

Further, according to an embodiment of the present invention, while the guide voice is being output, neither the other party nor the user himself/herself can hear the other party's voice. For this reason, while the guide voice is being output, there are problems such as the user becoming intimidated by hearing the angry voice of the person on the other end of the call, or the user's monologue being heard by the person on the other end of the call, causing the user to cancel the call. This makes it possible to prevent problems such as letting the other party know that you are unsure whether to continue or not. Additionally, the call record of the nuisance call that starts after the guide voice is output can be used for subsequent police investigations and evidence.

Next, a method for setting the automatic nuisance call recording function and an auxiliary function of the automatic nuisance call recording function will be explained. Note that, for convenience of explanation, the automatic nuisance call recording function will be collectively referred to as "nuisance call countermeasures" below.

<How to set up nuisance call countermeasures>
FIG. 6 is an explanatory diagram showing an example of a setting method for countermeasures against nuisance calls.
For example, when the user turns on the power for the first time after purchasing the communication terminal 200, the control unit 200
01 may display the initial setting screen G2 on the display unit 209.
The user may perform initial settings of the communication terminal 200 (such as setting a user ID and password) by operating a touch panel or the like according to the initial setting screen G2.

When the operation reception unit 208 receives input of initial settings from the user, it may send the settings to the control unit 201 . When the control unit 201 detects that the input of the initial settings has been completed,
A setting screen G3 for countermeasures against nuisance calls may be displayed on the display unit 209. Setting screen G for countermeasures against nuisance calls
3 may display buttons B3 and B4 for selecting whether to use or not use the nuisance call countermeasure. If the nuisance call countermeasure is not to be used, the user may tap the use permission/deny button B3. On the other hand, when using the nuisance call countermeasure, the user may tap the usage permission button B4.

When the operation reception unit 208 receives a user's selection operation of either the usage permission button B3 or the usage permission button B4, the operation reception unit 208 may send the result of the selection operation to the control unit 201. The control unit 201 may determine whether to enable or disable the nuisance call countermeasure application AP1 stored in the storage unit 205 based on the selection operation received from the operation reception unit 208. For example, if the user selects the usage permission button B3, the control unit 201 may determine that the nuisance call countermeasure should not be used. In this case, the control unit 201 may display the home screen G4 on the display unit 209 after disabling the nuisance call countermeasure application AP1.

On the other hand, if the user selects the usage permission button B4, the control unit 201 may determine that the nuisance call countermeasure should be used. In this case, the control unit 201 may display the home screen G4 on the display unit 209 after activating the nuisance call countermeasure application AP1. When the nuisance call countermeasure application AP1 is enabled, automatic execution of the nuisance call countermeasure application AP1 in the background may be started.

According to the above method, the user can complete the settings for countermeasures against nuisance calls when the communication terminal 200 is powered on for the first time. Therefore, the possibility of forgetting to set the nuisance call countermeasures can be reduced. That is, according to one embodiment of the present invention, damage caused by nuisance calls can be effectively suppressed.
Further, according to the above method, setting of countermeasures against nuisance calls can be completed with a single button operation. Therefore,
Even a user who is inexperienced in operating the communication terminal 200, such as an elderly person, can easily set countermeasures against nuisance calls. That is, according to one embodiment of the present invention, user convenience can be improved.

<Auxiliary function to prevent nuisance calls>
The auxiliary function for preventing nuisance calls is a function that displays a warning to the user that a nuisance call has been received.
FIG. 7 is a diagram for explaining an example of an auxiliary function for countermeasures against nuisance calls, and is an explanatory diagram when a warning is displayed on the incoming call history of nuisance calls.

When the control unit 201 receives an instruction to display the incoming call history from the user via the operation receiving unit 208, the control unit 201 may generate the incoming call history screen G5 and display it on the display unit 209.
To be more specific, for example, the storage unit 205 may store telephone numbers (incoming call numbers) of call parties to which the communication terminal 200 has received calls for a certain period of time in the past. Upon receiving the instruction to display the incoming call history, the control unit 201 may read out the incoming call number stored in the storage unit 205. and,
The control unit 201 may determine whether or not there is an incoming nuisance call by comparing the read incoming call numbers with the nuisance phone number list L1. When the control unit 201 determines that a nuisance call has arrived, the control unit 201 may display the incoming call number on the display unit 209 in association with a warning icon I1 that notifies the user that a nuisance call has arrived. At this time, the control unit 201 also displays the incoming call number determined not to be a nuisance call on the display unit 209, but since this point is the same as in the conventional case, a description thereof will be omitted.

In FIG. 7, a case has been described in which a warning is displayed in the history of incoming nuisance calls, but the same explanation can be applied to a case in which a warning is displayed in the history of outgoing nuisance calls.
The storage unit 205 may store telephone numbers (calling numbers) of call parties that the communication terminal 200 has called for a certain period of time in the past. When the control unit 201 receives an instruction to display the outgoing call history, the control unit 201 displays the storage unit 20
The calling number stored in 5 may be read out. Then, the control unit 201 may determine whether or not there is a call to a nuisance call by comparing the plurality of read out calling numbers with the nuisance call number list L1. When the control unit 201 determines that there is a call to a nuisance call, the control unit 201 may display the call number on the display unit 209 in association with a warning icon I1 that notifies the user that the call is a nuisance call.

According to this configuration, when there is a nuisance call in the call history, a warning icon is displayed in association with the originating or receiving number of the nuisance call to inform the user that the call is a nuisance call. be able to. By checking the warning icon, the user can reduce the possibility of accidentally calling a nuisance call that has been received or received. In addition, instead of (or in addition to) a warning icon, the calling or receiving number of the nuisance call may be displayed in color, or a text message indicating that the call is a nuisance call may be displayed to indicate that the call is a nuisance call. The user may be notified. That is, the warning display may be performed using any method that can make the user aware that the call is a nuisance call.

B. Others In the present embodiment described above, the recording of the nuisance call is started after the guide voice is output, but the present invention is not limited to this. For example, recording of a nuisance call may be started at the same time as the output of the guide voice starts. Note that "simultaneously" may include some errors as long as the function of the present invention is not impaired.

Further, in this embodiment, the guide voice output from the user's communication terminal 200 and the guide voice output from the other party's terminal are the same, but they may be different. For example, a guide voice with a stronger warning (e.g., ``nuisance calls may be prosecuted as 〇△ crime...'')
etc.) may be output from the other party's terminal.

Furthermore, in the above embodiments, "part" does not simply mean physical means;
This also includes cases where the functions of the "department" are realized by software. Furthermore, even if the function of one "unit" or device is realized by two or more physical means or devices, two or more "units"
The functions of a unit or device may be realized by one physical means or device.
