TECHNICAL FIELD OF THE INVENTION
The present invention relates to a communication terminal device such as a telephone, a facsimile device, and a portable telephone including a PHS, and more particularly, to a communication network service for notifying a caller's telephone number and a name registered for the telephone number when receiving a call. The present invention relates to a communication terminal device having a function of performing
[0002]
[Prior art]
2. Description of the Related Art In recent years, in communication using a communication network (network) such as an analog line, a digital line, and a mobile communication network, a telephone number of a communication terminal device of a transmission source (hereinafter, simply referred to as a “transmission source”) is referred to as a communication terminal of a destination. A source telephone number notification service such as a number display service for notifying a device (hereinafter simply referred to as a "destination") has been provided and has begun to be generally used.
For this reason, communication terminal devices such as telephones, facsimile machines, and mobile phones including PHSs use a function for using the source telephone number notification service (a function for detecting the source telephone number, a function for displaying the source telephone number). That have a function to perform such operations) are commercially available.
[0003]
Further, some communication terminal devices having such a function (hereinafter, referred to as "communication terminal devices compatible with the transmission source telephone number notification service") assume that the communication notified of the telephone number is safe. Some have an additional function of rejecting a response when the telephone number is not notified.
However, the fact that the telephone number is notified does not necessarily mean that the originating user can be trusted. For example, there is a so-called "one-way" nuisance call of a mobile phone that has become a social problem.
One-way call is a method of making a call to an unspecified number of mobile phones, ringing once, and then disconnecting the mobile phone. The user of the mobile phone receives the call history (the telephone number and the date and time of the incoming call). This is a malicious prank call in which calling back to a phone number in (remembered) leads to paid programs such as dating sites and adult programs. In addition, there is a violent business law of a one-off dealer who asks a user who made a call again in a similar manner to listen to the recorded tape and charge a large amount later.
[0004]
As described above, it is dangerous to easily trust the source that has notified the telephone number, and a communication terminal device that supports the source telephone number notification service cannot provide secure communication to the user.
Therefore, a source name notification service such as a name display service, which has advanced the source telephone number notification service one step further, has recently been started. The caller name notification service is a service for notifying a receiver of a name (phonebook name, telephone contractor name, billing address of the telephone company, etc.) registered for the telephone number of the caller. .
In order for the user to use the sender name notification service, a communication terminal device having a function corresponding to the service (a function of detecting the name of the sender, a function of displaying the name of the sender, etc.) is used. There must be.
[0005]
Therefore, a communication terminal device having these functions and various additional functions (hereinafter, referred to as a “communication terminal device compatible with a source name notification service”) is being developed.
For example, as disclosed in Patent Document 1, there is provided a memory for storing a telephone directory that stores a telephone number and a name in association with each other, and a message receiving unit that receives a message including a telephone number and a name of a caller. A first display mode in which a received message is displayed with priority, a second display mode in which information such as a name registered corresponding to the telephone number received in the telephone directory is displayed with priority, There is a communication terminal that allows a user to selectively set a third display mode for displaying both.
In this communication terminal, the user determines which display mode is set, and selectively displays the name of the received caller or the name registered in the telephone directory, or both, so that the user can select the display mode. Try not to get confused.
[0006]

[0007]
[Problems to be solved by the invention]
However, in the conventional communication terminal device compatible with the source name notification service as described in Patent Document 1, one or both of the name of the notified source and the name of the telephone directory are simply changed by the user. Since it is only displayed according to the selection, when the name of the sender is not notified, it cannot be distinguished whether it is a nuisance call, and there is a problem that the security of communication is not sufficiently improved.
Further, since the user does not know the notification / non-notification of the name of the caller until the user sees the display of the communication terminal device, even if the user repeatedly receives a nuisance call at midnight, for example, the communication terminal device is not notified every time the ring tone sounds. It is necessary to move to the installation position and check the display, which is inconvenient.
[0008]
Moreover, the ring tone continues to ring until the user responds to the communication or the caller disconnects the communication. Therefore, even if the user confirms that the name of the caller is not notified by the display of the communication terminal device, there is a problem that the communication must be answered in order to stop the ring tone. Was.
Furthermore, when the user is a child, an elderly person, or a person with weak vision, it is difficult to confirm the notification / non-notification of the name of the caller from the display of the communication terminal device. There is also a problem that notification / non-notification of the source name cannot be confirmed.
[0009]
In addition, even if the name of the caller of the incoming communication is not notified, the telephone number of the caller is stored as a received call history. There was also a problem that it might be suitable for the damage of "one-cut".
In other words, there is a problem that the conventional communication terminal device compatible with the source name notification service cannot perform sufficiently secure communication and is inconvenient.
The present invention has been made in view of the above problems, and has as its object to use a caller notification service to prevent a user from being bothered by a nuisance call and to enable more secure communication. .
[0010]
[Means for Solving the Problems]
The present invention is a communication terminal device having a function corresponding to a service of a communication network for notifying a caller's telephone number and a name registered for the telephone number when receiving a call, and achieves the above object. Therefore, when at least one of the caller's telephone number and name is notified, the notification detector detects the notification, and when the notification detector does not detect the caller's name, it responds to the incoming communication. Response rejection means for rejecting.
Further, the communication terminal device includes a call signal detecting means for detecting a call signal when an incoming call is received, and a sounding means for sounding a ring tone when the means detects the call signal. Is not detected, the response rejection means may not operate the sounding means even if the calling signal detection means detects the calling signal.
[0011]
Preferably, the response rejecting means includes means for sending a rejection signal for rejecting a response to the source to the communication network when the notification detecting means cannot detect the name of the source.
Further, there is provided an incoming call history storing means for selectively storing the contents of the notification detected by the notification detecting means as a history of the received communication, and when the answer rejecting means rejects the response to the incoming call, the incoming call history storage means Preferably, the means does not store the content of the notification detected by the notification detecting means.
[0012]
Alternatively, when the response rejection unit rejects the response to the incoming call, the incoming call history storage unit may add information indicating the rejection to the communication history stored at the time of the incoming call.
Further, the communication terminal device selects an arbitrary telephone number or name from the history stored in the incoming call history storage unit, and makes a call to the source of the telephone number or name selected by the selecting unit. When a telephone number or a name to which information indicating response rejection is added is selected by the selecting means, a means for inhibiting the calling by the selective calling means is provided. Good.
[0013]
In addition, when these communication terminal devices include a telephone directory registration unit that stores a telephone number, the response rejecting unit transmits the call detected by the notification detecting unit when the notification detecting unit cannot detect the name of the caller. A telephone number search means for determining whether or not the original telephone number matches any of the telephone numbers stored in the telephone directory registration unit, and the telephone number of the caller stored in the telephone directory registration unit It is more preferable not to reject the response to the incoming call when any of the above matches.
Further, the communication terminal device includes off-hook means for closing a line of the communication network, and if the notification detection means cannot detect the name of the caller, the response rejection means may not operate the off-hook means. .
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
First, a first embodiment, which is a basic embodiment of a communication terminal device according to the present invention, will be described with reference to FIGS.
FIG. 1 is a simplified block diagram showing the configuration of the telephone according to the first embodiment, and FIG. 2 is a flowchart showing the operation of the control unit when receiving a call.
As shown in FIG. 1, the telephone includes a main body including a control unit 1, a communication unit 2, an operation unit 5, and a display 6, and a handset 3 including a transmitter and a receiver.
The communication unit 2 has a modular jack. The communication unit 2 is connected to a telephone line 18 via a modular plug (not shown) and also connected to a handset 3. The telephone line is connected (closed) and disconnected by off-hook and on-hook of the handset 3. Then, it is controlled by a communication control unit 11 described later, and performs control necessary for communication with a caller and a call by the handset 3.
[0015]
The operation unit 5 includes a plurality of number buttons such as "0" to "9", "*", and "#", and a telephone button such as a "hook button", a "hold button", a "redial button", and a "answering machine" button. It consists of a plurality of setting buttons for setting various functions.
The display unit 6 is an LCD (liquid crystal display), and displays various information such as the notified telephone number and name of the caller, the setting state of the function of the telephone, and the operation guidance of the telephone.
Note that these communication unit 2, handset 3, operation unit 5, and display unit 6 are not specific to the present invention, and are similar to those provided in a general push-button telephone or the like. , And a detailed description thereof will be omitted.
[0016]
The control unit 1 includes a CPU 8 which is a central processing unit having various judgment and processing functions to control the operation of the entire telephone, and a rewritable nonvolatile memory storing fixed data and firmware (processing program) used by the CPU 8. A storage unit 10 including a flash ROM 9 as a memory, a RAM as a data memory for forming a work area necessary for the operation of the CPU and temporarily storing processing data of the CPU, and a non-volatile RAM for accumulating and storing various data. And a microcomputer including an input / output circuit (I / O) (not shown). The storage unit 10 can also be used as a buffer buffer for the flash ROM 9, and can also store and accumulate various information required for the telephone.
[0017]
The control unit 1 further includes a communication control unit 11 that controls the operation of the communication unit 2 and a display control unit 15 that controls the generation of display data on the display unit 6 and the brightness and character size of display. These control units are interconnected by a bus 17. Since the display control unit 15 is not unique to the present invention, a detailed description is omitted.
The communication control unit 11 also controls connection and disconnection of the telephone line performed by the communication unit 2. Further, when at least one of the caller's telephone number and the name is notified, the notification detector 12 detects the notification, and when the notification detector does not detect the caller's name, the communication received at that time is performed. Response rejection means 14 for rejecting a response is provided. The processing of each of these units is also executed by the judgment and processing function of the CPU 8.
[0018]
Next, the operation at the time of an incoming call by the control unit 1 of the telephone will be described with reference to the flowchart of FIG.
In step S1, the communication control unit 11 waits for an incoming call. If there is an incoming call, the process proceeds to step S2, and the notification detecting unit 12 performs a process of detecting the telephone number and name of the caller. Thereafter, in step S3, it is determined whether or not the telephone number or the name of the caller has been detected. Perform processing.
[0019]
In this ordinary communication processing, a ringing signal such as a bell sound is detected by detecting a call signal, and the user notices the ringing sound and takes a call (by lifting the handset 3 or pressing the hook button of the operation unit 5). When the telephone is off-hook), the communication unit 2 closes the line, sends a response signal in response to the call signal, and places the telephone in a state where the handset 3 can talk to the caller. The state in which the call can be made ends when a disconnection signal sent from the caller is detected or when the user hangs up (returns the handset 3 or presses the hook button of the operation unit 5 again to turn on the telephone). I do. However, since these processes are not specific to the present invention, a detailed description thereof will be omitted.
[0020]
On the other hand, if the notification detection unit 12 cannot detect the name of the caller in step S2, that is, if the name of the caller is not notified, the process proceeds from step S3 to step S5, and the response rejection unit 14 performs the process of rejecting the response. . This response rejection process may be terminated without performing the normal communication process of the step S4, but may be performed by performing any one of various processes according to the following embodiments or a combination thereof. The processing may be terminated.
Therefore, according to this embodiment, the telephone automatically rejects a response to an incoming call whose source name is not notified, and does not perform a normal communication process, thereby improving communication security. For example, it is possible to prevent the sender's name from erroneously responding to a non-notified incoming call.
[0021]
[Second embodiment]
Next, a second embodiment of the communication terminal device according to the present invention will be described with reference to FIGS.
FIG. 3 is a simplified block diagram showing the configuration of the telephone according to the second embodiment. The same parts as those in FIG. 1 are denoted by the same reference numerals, and their description is omitted. As shown in FIG. 3, this telephone has almost the same configuration as the telephone of the first embodiment shown in FIG. 1, but includes a ringing unit 7 in the main body, a ringing control unit 16 in a control unit 20, and communication. The only difference is that the control unit 21 is provided with the call signal detecting means 13. The ringing unit 7 is a ringing unit for ringing a ringing tone such as a bell sound to notify the user of an incoming call, and includes a sound source and a speaker. However, the ringing unit 7 is not unique to the present invention, and will not be described in detail. Omit
[0022]
The ringing control unit 16 of the control unit 20 has a function of operating the ringing unit 7 and adjusting the tone color, volume, and the like of the ringtone due to the ringing. The call signal detecting means 13 of the communication control unit 21 detects a call signal when the communication unit 2 receives a call. Normally, when the ringing signal detecting means 13 detects a ringing signal, the ringing control section 16 operates the ringing section 7 to ring a ringtone.
Such a function of detecting a call signal upon receiving a call and sounding a ring tone is also provided in a general telephone, and the telephone of the first embodiment is actually provided, although not shown. . However, in the second embodiment, if the notification detection unit 12 of the communication control unit 21 cannot detect the name of the caller at the time of an incoming call, the response rejection unit 14 rejects the response to the incoming call. In addition, it is characterized in that the ringing control unit 16 does not operate the ringing unit 7 even if the ringing signal detection unit 13 detects the ringing signal.
[0023]
FIG. 4 is a flowchart showing the operation of the control unit 20 in the telephone according to the second embodiment when receiving an incoming call. In this flowchart, the processing in steps S1 to S4 is the same as the processing in steps S1 to S4 in the flowchart shown in FIG. 2, except that the processing in step S7 is performed instead of step S5 in FIG. .
That is, in the flowchart of FIG. 4, if the name of the caller cannot be detected in step S2, that is, if the name of the caller is not notified, the process proceeds to step S3 without performing the normal communication processing in step S4. Proceeding to S7, the ringing control unit 16 does not operate the ringing unit 7 (so that the ringing tone does not ring) even if the ringing signal detection unit 13 detects the ringing signal, and the process ends.
[0024]
This corresponds to the function of the response rejecting means 14 in FIG.
According to the second embodiment, the user does not notice the incoming call because the ring tone does not sound even if the communication of which the name of the caller is not notified is received. Therefore, it is possible to prevent the user from erroneously answering the telephone call and not responding to the communication whose source name is not notified. Further, there is an advantage that the user can be prevented from being bothered by the ringtone of the nuisance call.
[0025]
[Application Example of Second Embodiment]
Here, an application example of the second embodiment will be described.
For example, the ringing control unit 16 and the ringing unit 7 can make a plurality of ringtones having different tones, pitches (frequency) or volume, and the case where the notification detection unit 12 can detect the name of the caller and the case where it cannot. May be used to generate ring tones having different timbres, pitches or volumes (or combinations thereof). Further, when a name of a specific transmission source is detected, a ring tone of a special tone, pitch or volume notifying the detection may be made.
Alternatively, a ring tone having a melody can be generated by the ringing control unit 16 and the ringing unit 7, and a melody of a different song or a melody of a different rhythm or tempo differs depending on whether or not the name of the caller can be detected. May be used to generate a ringtone.
[0026]
In this way, even if the user is not near the phone, the name of the caller is notified or not depending on the timbre, pitch or volume of the ringtone, the type of melody, its rhythm or tempo, etc. , Or whether it is an incoming call from a specific source.
Note that the tone color, pitch or volume, or melody of these ring tones can be obtained from a plurality of data stored in a memory such as the storage unit 10 in advance when the name of the caller is notified or not. It is preferable that the user can freely select and set the sound. Alternatively, the user may be allowed to store the ringtone that he or she has made on a personal computer or the like in the storage unit 10 so that the user can select and set it.
[0027]
In these cases, the telephone can generate different ring tones when the name of the caller is notified and when the caller's name is not notified, according to the preferences of various users.
Alternatively, the ringing control section 16 is provided with a voice generating means, and the ringing section 7 makes a voice announcement (for example, "a caller whose name of the caller has not been notified" or "a call from 〇〇 has been received." ) May be generated instead of the ringtone. Alternatively, a voice announcement may be generated together with a ringtone.
In this case, since the user can specify the source to some extent without checking the display on the display unit 6, the convenience of the telephone is further improved.
[0028]
The voice announcement can be generated by selecting from a plurality of digital voice data stored in advance in the storage unit 10 in accordance with the detection result of the notification detection unit 12 and performing digital / analog conversion on the selected voice data. That is, the user can freely select and set different voice announcements between a plurality of digital voice data having different voiceprints, contents, intonations (dialects) when the name of the caller is notified and when the name is not notified. It is good to Furthermore, the user may store his / her own announcement in the storage unit 10 in advance, and select and set the announcement.
[0029]
[Third embodiment]
Next, a third embodiment of the communication terminal device according to the present invention will be described with reference to FIGS.
FIG. 5 is a simplified block diagram showing the configuration of the telephone according to the third embodiment. The same parts as those in FIGS. 1 and 3 are denoted by the same reference numerals, and their description is omitted.
As shown in FIG. 5, this telephone has almost the same configuration as the telephone of the second embodiment shown in FIG. 3, but the control unit 25 is slightly different from the control unit 20 in FIG. The difference is that a response rejecting means 32 having a signal sending means 33 is provided.
In the communication control unit 31 according to the third embodiment, when the notification detection unit 12 cannot detect the name of the transmission source, the response rejection unit 32 sends a response to the transmission source by the rejection signal transmission unit 33. Is transmitted from the communication section 2 to the communication network via the telephone line 18. This function is also actually executed by the CPU 8.
[0030]
FIG. 6 is a flowchart showing the operation of the control unit 25 of the telephone according to the third embodiment when receiving an incoming call. In this flowchart, the processing in steps S1 to S4 and step S7 is the same as the processing in steps S1 to S4 and step S7 in the flowchart shown in FIG. 4, and the processing in step S8 following step S7 in FIG. The only difference is what you do.
In the flowchart of FIG. 6, if it is determined in step S3 that the name of the caller has not been detected, the process proceeds to step S7 without performing the normal communication processing in step S4, and the call signal detecting means 13 detects the call signal. Even if the ringing control unit 16 does not operate the ringing unit 7 (the ringing tone does not sound), the rejection signal sending unit 33 of the response rejecting unit 32 rejects the response to the caller in step S8. Is sent, the connection to the caller is rejected, and the process is terminated.
According to the third embodiment, when an incoming call whose name is not notified is received, the control unit 25 of the telephone sends out a rejection signal and automatically rejects the response, thereby improving communication security. I do.
[0031]
When the notification detection unit 12 detects the name of a specific transmission source previously stored in the storage unit 10 by the user, the rejection signal transmission unit 33 of the response rejection unit 32 rejects the response to the transmission source. A reject signal may be sent to reject the line connection with the caller.
In addition, the order of steps S7 and S8 in FIG. 6 may be exchanged to transmit the rejection signal first, or even if the process of not operating the ringing unit 7 in step S7 is omitted, the ringing tone sounds from somewhere. Since a rejection signal is transmitted without performing normal communication processing only by knowing that there is a call, there is no possibility of erroneously responding to a suspicious call.
[0032]
[Fourth embodiment]
Next, a fourth embodiment of the communication terminal device according to the present invention will be described with reference to FIGS.
FIG. 7 is a simplified block diagram showing the configuration of a telephone according to the fourth embodiment. The same parts as those in FIGS. 1, 3 and 5 are denoted by the same reference numerals. Omitted.
This telephone has almost the same configuration as the telephone of the third embodiment shown in FIG. 5, as shown in FIG. 7, but the control unit 26 is slightly different from the control unit 25 in FIG. The difference is that an incoming call history storage area 35 of a RAM is provided.
In the incoming call history storage area 35, the telephone number and name of the caller, which are the contents of the notification detected by the notification detecting means 12 of the communication control unit 31, are stored as the history of the incoming communication according to the judgment of the CPU 8. That is, the CPU 8 and the storage unit 34 having the incoming call history storage area 35 function as incoming call history storage means.
[0033]
FIG. 8 is a flowchart showing the operation of the control unit 26 of the telephone according to the fourth embodiment when receiving an incoming call. In this flowchart, the processing in steps S1 to S4 and steps S7 and S8 is the same as the processing in steps S1 to S4 and steps S7 and S8 in the flowchart shown in FIG. 6, and the normal communication in step S4 in FIG. Following the process, a process of storing the communication history (source phone number and name) is performed, and a process of not storing the source phone number in step S9 following the process of sending the rejection signal in step S8. The only difference is what you do.
That is, if it is determined in step S3 of the flowchart of FIG. 8 that the name of the transmission source has been detected, a normal communication process is executed in step S4, and then the name of the transmission source detected by the notification detection unit 12 in step S6 and The telephone number is stored in the incoming call history storage area 35 of the storage unit 34 as the communication history, and the process is terminated.
[0034]
When the telephone has a clock function and a calendar function, it is preferable to store the date and time of the incoming call together with the name and telephone number of the caller when storing the communication history.
On the other hand, if it is determined in step S3 that the name of the caller could not be detected, the ringtone is not sounded in step S7, a rejection signal is sent out in step S8, and the phone number of the caller is stored in step S9. The process is terminated so that the incoming call history is not stored in the incoming call history storage area 35 of the unit 34, that is, the telephone number of the caller is not left as a communication history. In step S9, the process may be terminated without doing anything, but for the sake of simplicity, it is described that a process of "not storing the telephone number of the caller" is performed.
[0035]
According to the fourth embodiment, it is possible to reject a response to an incoming call whose name of the caller is not notified and, even if the telephone number of the caller is notified, the telephone number is not stored as the call history. Therefore, it is possible to prevent the user from calling the source of the suspicious telephone number for which the name was not notified by selecting the incoming call history, and to be harmful to damage such as "one-way call". Therefore, communication security is further improved.
If the name of the caller is not notified, information other than the telephone number of the caller (for example, incoming date and time) may be left as an incoming call history. At this time, it is also possible to temporarily store information such as the telephone number of the caller telephone and the date and time of the incoming call as a history of incoming calls, and then delete only the information of the telephone number.
[0036]
In the flowchart shown in FIG. 8, when it is determined in step S3 that the name of the transmission source has been detected, the processing is performed in the order of storing the communication history in step S6 after performing the normal communication processing in step S4. However, the normal communication processing may be performed after the communication history is stored by reversing the execution order of steps S4 and S6.
Similarly, the order of steps S7, S8, and S9 executed when it is determined in step S3 that the name of the transmission source could not be detected may be appropriately changed, and one or both of steps S7 and S8 may be omitted. You may.
[0037]
[Fifth Embodiment]
Next, a fifth embodiment of the communication terminal device according to the present invention will be described with reference to FIG.
The configuration of the telephone according to the fifth embodiment is the same as that of the telephone according to the fourth embodiment shown in FIG. 7, except that the functions of the CPU 8 and the storage section 34 as incoming call history storage means are slightly different.
FIG. 9 is a flowchart showing an operation at the time of an incoming call by the control unit 26. The processes of steps S1 to S4 and S6 to S8 correspond to the corresponding steps in the flowchart of FIG. The processing is the same as the above.
[0038]
In the fifth embodiment, if it is determined in step S3 in FIG. 9 that the name of the caller has not been detected, the ringtone is not sounded in step S7, and a rejection signal is sent in step S8. The fourth point is that, in step S10, the communication history (the telephone number of the caller) is added to the information indicating rejection of the response and stored in the incoming call history storage area 35 of the storage unit 34, and then the process is terminated. This is different from the embodiment. The information indicating the response rejection can be 1-bit or 2-bit identification data.
When the telephone has a clock function and a calendar function, when the telephone number of the caller is added as information indicating rejection of the response in step S10 and stored as a received call history, information on the date and time of the received call is also stored. Good.
[0039]
According to the fifth embodiment, it is possible to reject a response to an incoming call whose source name is not notified, and the incoming call history is stored, but information indicating that the answer is rejected is added. Therefore, when the user selects the communication history and calls back the caller, the user can be alerted to the security of the communication by using the added information.
In the flowchart shown in FIG. 9 of the fifth embodiment, the execution order of steps S4 and S6 is interchanged, the execution order of steps S7, S8, and S10 is appropriately changed, and the processing of steps S7 and S8 is performed. Either or both may be omitted.
[0040]
Next, the operation at the time of selective calling using the incoming call history by the control unit of the telephone according to the fifth embodiment will be described with reference to the flowchart of FIG.
When the incoming call history is selected by the operation of the operation unit 6 shown in FIG. 7, the control unit 26 starts the operation of FIG. 10, and the incoming call stored in the incoming call history storage area 35 of the storage unit 34 in step S101. The history (information such as the telephone number and name of the incoming caller) is displayed on the display unit 6, and an arbitrary telephone number or name is selected from the communication history.
[0041]
When it is selected and a call is instructed, it is determined in step S102 whether information indicating rejection of a response is added to the history (telephone number or name) of the selected communication.
If the information indicating that the response has been rejected has not been added, the process proceeds to step S103 and the source of the selected telephone number (the telephone number stored correspondingly even when the name is selected) is sent to the sender. A call is made by automatic dialing, and normal communication processing is performed in step S104, and the processing is terminated. The normal communication process in this case is a normal communication (call) process in the calling telephone.
[0042]
On the other hand, if the information indicating rejection of the response has been added, the process proceeds to step S105, in which calling to the selected telephone number is prohibited, and the process ends without performing the normal communication process.
In this way, when a call is instructed by selecting an incoming call history whose caller name is not notified, information indicating rejection of a response is added to the selected incoming call history. Since the process is terminated without calling the telephone number, it is possible to prevent the user from accidentally selecting and calling the telephone number whose name in the incoming call history is not notified, thereby further improving communication safety. I do.
[0043]
When the user confirms the telephone number of the incoming call history selected by the user and confirms that the caller is not a suspicious caller, the incoming call history to which information indicating that the response is rejected is added by operating the button of the operation unit 5 The function to prohibit the call to the telephone number of the user can be released, and the call by the automatic dialing is also performed to the telephone number of the incoming call history to which the information indicating the rejection of the answer is added, and the normal communication (call ) Processing can also be enabled.
[0044]
[Sixth embodiment]
Next, a sixth embodiment of the communication terminal device according to the present invention will be described with reference to FIGS.

It is determined whether or not the transmitted caller telephone number matches one of the telephone numbers stored in the telephone directory registration unit.
[0047]
If the caller's telephone number matches one of the telephone numbers stored in the telephone directory registering section 45, the process proceeds to step S4 in the same manner as when the caller's name could be detected in step S3, and normal communication processing is performed. Is performed, and the process ends. That is, in this case, the call can be made with the caller without rejecting the response to the incoming call.
If the caller's telephone number does not match any of the telephone numbers stored in the telephone directory registration section 45, the process proceeds to step S7 in the same manner as in the case where the caller's name could not be detected in the flowchart of FIG. A ringing tone is not sounded, a response rejection signal is sent out in step S8, and the process ends without performing normal communication processing.
[0048]
According to the sixth embodiment, the communication of which the name of the caller is not notified is performed in the case where the notified caller's telephone number is registered or not registered in the telephone directory registration unit, Separates incoming calls from known sources (incoming calls from secure sources) and incoming calls from unknown sources (incoming calls from unsecured sources), and responds to the former. To make calls possible and reject the latter. Therefore, the security of communication can be ensured, and more detailed correspondence can be made with respect to the source, thereby improving the convenience of the telephone.
Also in this embodiment, the execution order of steps S7 and S8 can be exchanged, or one or both of them can be omitted.
[0049]
In addition, in combination with the fourth embodiment shown in FIG. 8 or the fifth embodiment shown in FIG. If the original phone number is stored in the phonebook registration unit, the communication history (and the source phone number and name, if detected) is also stored. If the original telephone number has not been stored in the telephone directory registration unit, the communication history of the incoming call may not be stored, or information indicating rejection of the response may be added and stored.
[0050]
