Abstract

<P>PROBLEM TO BE SOLVED: To limit incoming of a malicious single-ring-and-hang-up call abusing an incoming history function. <P>SOLUTION: An access time measuring means 10 is provided in a control unit 1. The time (access time) from the start of the incoming to the reception of a disconnect message is measured by the access time measuring means 10. The measured access time is stored in an incoming history data base along with the incoming history. When the incoming history is displayed on a display 3, the access time for the incoming call is also displayed so that the user can judge whether it is the incoming of the single-ring-and-hang-up call or not. Further, a blacklist for storing a calling party number judged to be the source of the incoming of the single-ring-and-hang-up call, and a white-list for storing the telephone numbers for friends etc., are provided. The incoming from a number registered in the blacklist is rejected or is transferred to a phone-answering machine. The incoming from a number registered in the white-list is treated as incoming intact. The incoming from an unknown number is accessed after a preset time has been elapsed. <P>COPYRIGHT: (C)2004,JPO

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile communication device such as a mobile phone and a PHS.
[0002]
[Prior art]
2. Description of the Related Art In a portable communication device such as a mobile phone or a PHS, there is known an incoming call history function for storing a date and time, a telephone number (when there is a caller ID notification), and the like when an incoming call is received. The user can make a call again by referring to the incoming call history, for example, when the call is not answered even if there is an incoming call.
Conventionally, as a function of a mobile phone, a designated incoming call rejection function of rejecting an incoming call for a telephone number registered in advance has been provided.
[0003]
[Problems to be solved by the invention]
In recent years, the act of calling a mobile phone number for a moment and disconnecting it, so-called "one-way call", is a malicious service that charges a large amount of service usage fee to users who responded by looking at the history of one-time incoming calls and replying And so on.
However, mobile phone operators cannot limit incoming and outgoing calls from technically possible, but legal or contractual reasons, even if they come from an apparently malicious provider. Coping was practically difficult.
Accordingly, an object of the present invention is to provide a portable telecommunication device having a function of automatically restricting one-ring incoming calls.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the portable communication device of the present invention has an incoming call history storage unit that stores incoming call history information when there is an incoming call, and the incoming call history information can be displayed on a display unit. Ringing time measuring means for measuring a ringing time, which is the time from the start of the incoming call to the time when the incoming call is disconnected from the network side, when the incoming call is received, Means for storing the call time measured by the call time measuring means in the incoming call history storage means together with the incoming call history information, so that when the incoming call history information is displayed on the display section, the call time is also displayed. It was done.
[0005]
Also, it has a one-cut time setting memory that can set an arbitrary time, and when there is an incoming call, the user is kept from the start of the incoming call until the time set in the one-cut time setting memory elapses. Calls are not made.
Furthermore, the incoming call history information is not stored for an incoming call that is shorter than the time set in the one-ring time setting memory.
Furthermore, it has a blacklist storage unit that stores a telephone number set by the user, and an incoming call from a caller number stored in the blacklist storage unit is immediately rejected, or It is designed to be forwarded to an answering machine service.
[0006]
Still further, there is provided a means for storing, in the blacklist storage means, the caller number of the selected call history information from the call history information stored in the call history storage means.
Still further, if the ringing time included in the selected incoming call history information is longer than the time set in the one-ring time setting memory, the ringing time is set in the one-ring time setting memory. Means.
[0007]
Furthermore, it has whitelist storage means for storing a telephone number set by the user, and for an incoming call from a caller number stored in the whitelist storage means, a call to the user is immediately made. Is what is being done.
Still further, there is provided a means for storing the telephone number stored in the memory dial storage means in the white list storage means.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a block diagram showing an outline of a hardware configuration of a portable communication device of the present invention.
In this figure, 1 is a control unit composed of a microprocessor or the like, 2 is a memory unit for storing various control programs and various data, 3 is a display unit, 4 is operation keys, 5 is an antenna, 6 is a transmission / reception unit, and 7 is a voice. A signal processing unit that performs signal processing and the like, 8 is a microphone, and 9 is a speaker.
Here, the memory unit 2 stores various data such as a memory dial (phone book) database, an incoming call history database, an outgoing call history database, and a blacklist database and a whitelist database described later. Further, the control unit 1 is provided with a ringing time measuring means 10 for measuring a ringing time of an incoming call (ringing time of a ringing tone). For example, the ringing time measuring means 10 starts the measurement by receiving a call setting message and ends the measurement by receiving a disconnection message from the network side, whereby the incoming call is disconnected from the network side from the start of the incoming call. It measures the time it takes until it is completed, and is actually realized by software.
[0009]
FIG. 2 is a diagram showing an example of the incoming call history database stored in the memory unit 2.
As shown in this figure, in the present invention, the incoming call history database not only stores the date and time of the incoming call, the caller ID (if the caller ID is notified) and the incoming call type, but also stores the incoming call type. The call time measured by the call time measuring means 10 is also stored.
When the user displays the incoming call history on the display unit 3, the call time of the incoming call is also displayed. Therefore, the user can see the call time displayed in the incoming call history of the missed call. It is possible to recognize whether or not the incoming call has a high possibility of what is called a one-way call. Therefore, it is possible to prevent the user from making a call to the caller ID in the incoming call history having a high possibility of being cut off.
[0010]
FIG. 3 is a flowchart showing the flow of processing when there is an incoming call according to the first embodiment of the present invention.
As shown in this figure, when an incoming call is received, the date and time of the incoming call and the caller ID (when the number is not notified, the reason: non-notification setting / public telephone / not notification) are recorded in the reception history database and displayed on the display unit. In addition to displaying an incoming call, ringing or ringing of a melody or vibration of a vibrating device is started based on a user's setting to start a call, and further, the ringing time measuring means 10 starts measuring a ringing time. (S11). Then, it is determined whether or not the incoming call has been disconnected from the network side (S12), whether or not the user has performed a call rejection operation (S13), and whether or not the user has answered the incoming call (S14). .
When the disconnection message is received from the network side and the incoming call is terminated (S12: YES), the measurement of the call time by the call time measuring means 10 is terminated (S15), and the incoming call history information of the call is stored in the incoming call history database. , The type (missed call) and the measured calling time are recorded (S16).
If the user performs a call rejection operation (YES in S13), the call is terminated by sending a release completion message or the like, and the call time measurement is terminated (S17). Is recorded (S18). Note that the incoming call type may be a missed call, and the measured calling time may or may not be stored.
Further, when the user responds to the incoming call (YES in S14), the measurement of the calling time is terminated, and the call is started (S19).
[0011]
As described above, according to this embodiment, when a call is received and the call is disconnected by the disconnect message from the network side, the calling time, that is, the incoming call (reception of the call setup message) The time from when the call is received to the disconnection message is measured, and the measured calling time is recorded in the incoming call history of the missed call. Then, the ringing time recorded when displaying the incoming call history is also displayed.
FIG. 4 is a diagram showing a display example of the incoming call history. As shown in this figure, according to the present invention, since the ringing time measured and recorded as described above is displayed during the display of the incoming call history, the user can determine whether the incoming call is a so-called one-ring call. Can be determined, and making a call to the caller of the incoming call can be prevented.
In the incoming call history display, if the calling time is shorter than a predetermined time (for example, 2 seconds), the display color is set to be different from other information, or the fact is indicated. Attention may be drawn to the user by adding information shown.
[0012]
As described above, according to the first embodiment of the present invention, the ringing time of the incoming call is stored in the incoming call history database and displayed as the incoming call history information. It is possible for the user to make a determination, and it is possible to prevent the user from making a return call for a one-call call.
[0013]
Next, a second embodiment of the present invention will be described. In this embodiment, the memory unit 2 is provided with a one-cut time setting memory capable of setting an arbitrary time, and when an incoming call is received, the time stored in the one-cut time setting memory (one-cut time setting memory) is set. During this period, no call is made to the user, and a call is made to the user for the first time when the ringing time (elapsed time from the incoming call) becomes longer than the one-ring time. . Here, the user can set an arbitrary one-cut time in the one-cut time setting memory.
[0014]
FIG. 5 is a flowchart showing the flow of processing when there is an incoming call in the embodiment for performing the call suppression.
As shown in this figure, when an incoming call is received, the date and time, the caller ID, etc. are recorded in the incoming call history database, and the ringing time measuring means 10 starts measuring the ringing time of the incoming call (step). S21). However, in this embodiment, the display of the incoming call on the display unit, the ringing of the incoming call sound, or the vibration of the vibrating device is not started yet, and is kept in the off state. That is, at this stage, the user is not called.
[0015]
Then, without receiving a disconnection message from the network side, it is determined whether or not the ringing time of the incoming call (the elapsed time from the incoming call) has exceeded the time set in the one-time ringing time setting memory (step). S22) If the one-time ringing time has elapsed without receiving the disconnection message from the network side, it is determined that the call is not a one-time ringing call. Is notified of the incoming call, and a normal incoming call operation is performed (step S23). On the other hand, if the disconnection message is received from the network side before the set one-hang-up time elapses and the call is disconnected, it is determined that the incoming call is a one-hang-up call. The recorded incoming call history information for the call is deleted (step S24). As a result, the user does not perceive any incoming call history for the incoming call determined to be a one-way call.
It should be noted that only the record may be left without deleting the incoming call history in step S24. In this case, the ringing time of the call is recorded in the incoming call history, as in the first embodiment.
[0016]
According to the embodiment in which the call is suppressed, the user does not recognize the incoming call having the ringing time shorter than the one-hanging time arbitrarily set in the one-hanging time setting memory. Can be eliminated.
[0017]
By the way, the embodiment shown in FIG. 5 uniformly treats an incoming call whether it is a caller ID non-notification, a public telephone, or a caller ID notification. During the off-time, the user is not called.
Therefore, still another embodiment of the present invention will be described which uses a blacklist recording telephone numbers determined to be a malicious sender of a user and a whitelist recording telephone numbers of a user's family and acquaintances. According to this embodiment, when a user receives a call again from a number determined to be a malicious one-way call based on the ringing time of the incoming call history in the above-described first embodiment or the like, the user is notified of such a case. Incoming calls can be restricted, and for incoming calls from a known telephone number such as the one stored in the memory dial by the user, a normal incoming call operation is performed without blocking the call as in the above-described embodiment. Can be performed.
[0018]
FIG. 6 is a diagram showing an example of a blacklist database and a whitelist database stored in the memory unit 2. As shown in this figure, each of the blacklist database and the whitelist database stores a predetermined number of telephone numbers. The user can arbitrarily read and edit the blacklist database and the whitelist database. In addition, the caller ID can be stored in the blacklist database while the incoming call history is displayed. Further, data of a memory dial (phone book or address book) provided as an existing function in the mobile communication device can be transferred and stored in the white list database.
[0019]
FIG. 7A is a flowchart illustrating a flow of a process of registering a blacklist when the incoming history information is displayed on the display unit 3, and FIG. 7B is an example of an incoming history display at that time. FIG.
As shown in FIG. 7A, the user displays the incoming call history on the display unit 3 and confirms it (step S31). FIG. 7B is a diagram showing an example of the incoming call history display at this time. As shown in the figure, a selection unit for whether or not to register in the blacklist is displayed at the bottom of the incoming call history display screen. ing. If the user decides to register in the blacklist based on the incoming call history, the user selects blacklist {1} Yes using the operation keys. When the blacklist registration operation is performed in this manner (S32: YES), the caller number included in the incoming call history information is recorded in the blacklist database (S33). Then, it is determined whether or not the ringing time included in the incoming call history is longer than the one-ring time recorded in the one-ring time setting memory (S34). Is set in the one-cut time setting memory (S35). Then, it is determined whether or not there is a next incoming call history to be processed (S36), and if not, the next incoming call history is displayed (S37), and the above-described processing is repeated.
[0020]
As described above, the caller number of the incoming call history selected by the user can be registered in the blacklist database from the state in which the incoming call history is displayed on the display unit. If the ringing time included in the selected incoming call history is longer than the one-hanging time set in the one-hanging time setting memory, the ringing time is set as a new one-hanging time. It is stored in the memory. Therefore, even when there is a one-ring incoming call with a ringing time longer than the time set in the one-ring time setting memory, if the user determines from the incoming call history that the incoming call is a malicious one-ring incoming call, the ringing time is determined. Becomes a new one-cut time, and thereafter, a one-call incoming call shorter than the new one-cut time is subject to the above-described call suppression. Therefore, even if a malicious caller changes the ringing time of a one-call call to a longer one, it is possible to cope with it.
[0021]
FIG. 8 is a flowchart showing the flow of processing at the time of an incoming call in the embodiment having the blacklist and the whitelist. In this embodiment, the incoming call for which the caller ID is not notified and the incoming call from the number registered in the whitelist perform a normal incoming call operation without performing the above-described call suppression, and are registered in the blacklist. Incoming calls from existing phone numbers are immediately forwarded to the call rejection or answering machine function, and call suppression is performed only for incoming calls from phone numbers that are not recorded in the whitelist or the blacklist. Things.
In FIG. 8, when there is an incoming call, the date and time of the incoming call and the caller number are recorded in the incoming call history database (step S41), and it is then determined whether or not the incoming call includes the caller number. (Step S42). Here, when the caller ID is not included due to caller ID non-notification or the like (NO in S42), a normal incoming call operation is performed (S50).
[0022]
On the other hand, when the caller number is included (S42: YES), the caller number is compared with the stored contents of the blacklist database and the whitelist database (S43), and (1) registration in the whitelist If the telephone number has been entered, a normal incoming call operation is performed (S44).
(2) If the telephone number is registered in the black list, the telephone number is immediately transferred to the answering machine function without calling the user (S45), or an open completion message is transmitted to reject the incoming call. (S45 '). Which of S45 and S45 'is executed is arbitrary, but may be selected and set by the user. As the answering machine function in step S45, a simple answering machine function (recording a message in a memory in the mobile station) installed in the mobile station may be used, or the message may be stored on the network side. An answering machine service may be used. Alternatively, a transfer telephone service may be executed. In this way, incoming calls from numbers registered in the blacklist database are restricted.
[0023]
If the caller number included in the incoming call is an unknown number not registered in (3) neither the black list nor the white list, the process proceeds to step S46, where the ringing time measuring means 10 terminates the call. The measurement of the elapsed time (ringing time) from is started, the ringing of the ringtone or the vibration device is kept off, and the calling operation to the user is suppressed. Then, it is determined whether or not the one disconnect time set in the one disconnect time setting memory has elapsed without receiving the call disconnect message from the network side (S47). When the one-off time has elapsed (YES in S47), a ringing tone is sounded or a vibrating device is operated to start a call to the user and perform a normal incoming call operation (S48). ).
On the other hand, if the call disconnection message is received from the network side before the one-off time set in the one-off time setting memory elapses, the process proceeds to step S49, and the caller number is registered in the blacklist. At the same time, the incoming call history recorded in step S41 is deleted from the incoming call history database. Thus, the user does not perceive the incoming call.
[0024]
When a disconnection message is received from the network after the normal incoming call operation is performed in step S48, the call time is measured in the same manner as in step S15 of the embodiment shown in FIG. Is ended, and the measured calling time is recorded in the incoming call history database. Therefore, the user sees the incoming call history of the missed call and registers the caller number of the incoming call history in the blacklist database as in the embodiment shown in FIG. As a result, the ringing time of the incoming call is set as a new one-cut time, and the one-cut time is used thereafter.
[0025]
According to this embodiment, an incoming call from a number recorded in the blacklist is immediately transferred to an answering machine (S45) or rejected (S45 '), so that the user can take the malicious intent. There is no one-call recognition. In particular, according to the embodiment in which the transfer to the answering machine is performed, if a call is made from a person who is not registered in the memory dial, and if the call is cut off for a few seconds, it is unfortunately registered in the blacklist. Since a well-meaning person can communicate the intention of the conversation to the user by answering machine, it is possible to avoid the possibility of blocking the other person.
Also, for an incoming call from a number recorded in the whitelist, a normal incoming call operation can be performed without performing the above-described incoming call restriction.
Further, in step S49, the telephone number of the incoming call disconnected in a shorter time than the one-time setting time set in the one-time setting memory is automatically registered in the blacklist. The user does not recognize a new one-way call from the user and can be automatically recorded in the blacklist.
[0026]
In the above-described embodiment, both the blacklist database and the whitelist database are provided. However, the present invention is not limited to this. Only the blacklist database or only the whitelist database is provided. Is also good.
[0027]
Further, the functions of the present invention described above can be constructed as an application program executed in a mobile communication device. In this case, by downloading this application program, not only the new model corresponding to the present invention described above, but also a one-ring incoming call can be prevented not only for a mobile device capable of executing an existing application program on the market. It becomes possible.
Furthermore, the blacklist database and the whitelist database can also be used as a function for suppressing unwanted calls (or e-mails) other than the one-ring prevention.
[0028]
【The invention's effect】
As described above, according to the portable communication device of the present invention, since the user can check the ringing time of each incoming call history, it is possible to check whether or not the one-time call is performed, and to call the user carelessly. It is possible to prevent re-calling.
In addition, according to the portable communication device of the present invention having the one-ring time setting memory, the user does not perceive a one-ring incoming call that is shorter than the set calling time.
Further, according to the embodiment having the blacklist database, once-detected one-way incoming calls are automatically rejected thereafter, so that the load on the network due to one-time incoming calls is reduced.
Furthermore, according to the portable communication device of the present invention having the whitelist database, incoming calls from the numbers recorded in the whitelist are not suppressed.
As described above, according to the mobile communication device of the present invention, the meaning of the one-way call itself is lost, and as a result, the one-way call transmission can be suppressed.
