Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a telephone such as a fixed telephone, a mobile telephone, a car telephone, and a portable telephone (PHS), which can specify a telephone number of a caller and save the specified telephone number together with additional information in a memory. The present invention relates to an incoming call control method, an incoming call control program, and an incoming call control program for a telephone.
[0002]
[Prior art]
In order to avoid unwanted calls such as pranks and sales, some conventional telephones switch the incoming call processing according to the telephone number of a caller (hereinafter, referred to as a "source"). For example, if the phone number of the caller notified at the time of the incoming call is registered in the memory as a call rejection target, the type of processing held in association with the number, specifically, "silence", "automatic answer" Incoming call operation is performed according to the above-mentioned method (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-10-42036
[Problems to be solved by the invention]
However, in a conventional telephone, only a predetermined correspondence can be selected with respect to a telephone number registered in advance, and when a call is made from an unregistered number, the person who received the call (hereinafter referred to as a “destination”) ) Must judge the response. At this time, if the called party cannot answer the call or the call is cut off before answering, the called party must determine whether to loop back the number left in the received call history.
[0005]
Here, it is highly empirical that a phone call from an unregistered and unknown number that has been immediately disconnected after receiving a call is highly likely to be a wrong call. , Likely cut soon). If the callee does not know and re-calls, the caller is wasted due to erroneous operation of the caller.
[0006]
In addition, there are unscrupulous agents who abuse the kindness of human beings, who will call back if there is an incoming history of the number seen for the first time, which is a social problem. This is a call that is called out for a short period of time so that the callee cannot be reached immediately (so-called "one call"), leaving only the number in the call history, and advertising when the callee dials the number again Such a guide tape is used to charge a nominally large fee such as an information fee or an overdue fee at a later date.
[0007]
As measures to avoid being involved in such troubles, (1) do not redo an unknown number, (2) set the number as an object to be rejected, (3) automatically answer 0 seconds after receiving an incoming call (Because it is usually difficult to manually go off-hook within a short call such as “one-ring” after receiving a call), the above solution still does not work. Some problems remain.
[0008]
For example, the above method (2) cannot be applied to an unknown number that arrives for the first time because the destination already knows the number in advance or can be registered only after there is at least one incoming call. If the first incoming call is asleep, the call is suddenly awakened, which is very annoying. While you are asleep, you can mute the ringtone and make it answer your answering machine, but then you will not be able to get the necessary or emergency calls.
[0009]
In addition, since the setting of the above (3) is also applied to a call from a person other than an unscrupulous trader, for example, even if the destination cannot answer the call, if this setting is left unattended, the caller is automatically responded to by the caller. In addition, you will be charged, and you will not be able to talk now, so you will have to call back again or here, and it will cause trouble to the general public who is not a vicious trader.
[0010]
In order to solve the above-mentioned problem of the prior art, the present invention confirms whether or not the caller has a willingness to make a conversation prior to notifying the user of an incoming call, and takes a wrong telephone call without such intention or a so-called "one-way call". An object of the present invention is to provide a telephone incoming call control method, a telephone incoming call control program, and a telephone that can enhance convenience and user safety by avoiding the following.
[0011]
[Means for Solving the Problems]
In order to solve the above-described problems and achieve the object, a method for controlling an incoming call of a telephone, an incoming call control program, or a telephone according to the present invention, when a telephone number of a caller is not registered in a memory, goes off-hook and Is measured, and when the transmission is not abandoned until the time reaches the predetermined time, the user is notified of the incoming call.
[0012]
Further, the incoming call control method according to the present invention, when the telephone number of the caller is not registered in the memory, goes off-hook and measures the time from the off-hook, until the time reaches a predetermined time. When the call is abandoned, the telephone number is registered in the memory as an abnormal number.
[0013]
Further, in the incoming call control method according to the present invention, when the telephone number of the caller is registered in the memory as the abnormal number, the user goes off-hook and measures time from the off-hook, and the time reaches a predetermined time. If the call is not abandoned during this period, the user is notified of the incoming call.
[0014]
According to these inventions, when a call is received from a number that is not registered in the memory or a number that was cut off immediately before, the caller's action after automatic answering (turn off immediately, wait for a while, etc.) , The presence or absence of a conversation intention is determined, and only when it is determined that there is a conversation intention, the called party is actually called.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Exemplary embodiments of the present invention are explained in detail below with reference to the accompanying drawings. It should be noted that the incoming call control function described below can be implemented by a circuit or software for part or all of the function.
[0016]
FIG. 1 is an explanatory diagram showing the overall configuration of the telephone according to the embodiment of the present invention. As shown in the figure, the telephone according to the present embodiment includes a transmission control unit 1 that performs processing at the time of outgoing call, an operation at the time of outgoing / incoming, registration / de-registration of a telephone number, setting of a measurement time by a timer 8 described later, and the like. An operation unit 2 including various buttons for performing the operation; a display unit 3 for displaying personal information of a caller and various messages to be described later; an incoming call control unit 4 for performing processing such as ringing upon receiving an incoming call and reproducing a response message; RAM 5 for storing histories and telephone numbers (normal numbers and abnormal numbers to be described later), ROM 6 for storing software and the like, timer control unit 7 for controlling start / stop of timer 8 described later, control of timer control unit 7 A timer 8 operating below, an input / output unit 9 including a microphone for voice input and a speaker for voice output, and a control unit 10 for controlling the operation of each of the above units are provided. It is a non-configuration.
[0017]
Next, the incoming call control function of the telephone according to the present embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing the procedure of the whole incoming call process when a call is received. FIG. 3 is an incoming call process when the caller's telephone number is an unregistered number (step S5 in FIG. 2), and FIG. 4 is an incoming call process when the caller's telephone number is an abnormal number described later (FIG. It is a flowchart which shows the procedure of 2 steps S6) in detail, respectively.
[0018]
In FIG. 2, when the incoming call is notified from the incoming call control unit 4 to the telephone (step S1: Yes), the control unit 10 first determines whether or not the caller number is notified for the incoming call (step S2). . If the caller number has not been notified (step S2: No), it is stored in the incoming call history (or missed incoming call history; the same applies hereinafter) in the RAM 5 as an incoming call of non-notification setting (step S7), and the incoming call control unit 4 to perform a normal incoming call process (step S8).
[0019]
On the other hand, when the caller number is notified (step S2: Yes), the control unit 10 acquires the number and determines whether the number is registered in the RAM 5 (step S3). If the number is not registered in the RAM 5 (step S3: No), the process proceeds to an unregistered number reception process described in detail with reference to FIG. 3 (step S5).
[0020]
If the source number is registered in the RAM 5 (step S3: Yes), the control unit 10 determines whether the number is registered as an abnormal number (step S4), and is registered as an abnormal number. In this case (step S4: Yes), the process proceeds to the abnormal number receiving process (step S6) described in detail with reference to FIG. On the other hand, if the registration of the caller number is not an abnormal number (step S4: No), the control unit 10 stores the number in the incoming call history in the RAM 5 (step S7) and controls the incoming call control unit 4 to perform normal operation. The following incoming call processing is performed (step S8).
[0021]
Next, the unregistered number receiving process (step S5) shown in FIG. 2 will be described in detail with reference to FIG. When the caller number is an unregistered number, the control unit 10 first determines whether or not the off-hook setting is set for this telephone (step S51). If the immediate off-hook setting has not been made (step S51: No), the process proceeds to step S56 to be described later, while if the immediate off-hook setting has been made (step S51: Yes), the incoming call control unit 4 is controlled. To actually go off-hook (step S52), and instruct the timer control unit 7 to start the timer 8 (step S53). Further, an automatic response message such as "calling now" is transmitted to the transmission source (step S54).
[0022]
The timer control section 7 stops the timer 8 when a preset time has elapsed, and notifies the control section 10 of the fact that the time has elapsed. The control unit 10 does not abandon the transmission until the notification is received from the timer control unit 7 (until the time elapses). When the message is being reproduced, if the user has not waited for a predetermined period of time without hanging up (step S55: No), the user is notified of an incoming call, for example, a ringtone is sounded (step S56), and the telephone number of the caller is stored in the RAM 5. (Step S57), and controls the incoming call control unit 4 to perform a normal incoming call process (Step S58).
[0023]
On the other hand, if the caller abandons the call within the above time (step S55: Yes), the control unit 10 controls the incoming call control unit 4 to make it go on-hook (step S59), and sets the telephone number of the caller as an abnormal number. It is registered in the RAM 5 (step S510), and the user is notified of that (step S511). Specifically, for example, the display unit 3 is controlled to display a message such as "The telephone was disconnected within the set time, so it was registered as an abnormal number".
[0024]
As can be seen from the above description, the time measured by the timer 8 is the time from when the telephone goes off-hook to when the user is notified of the incoming call. In many cases, the so-called "one call" is cut off by sounding a ringing tone (ringback tone) only once. Therefore, it is desirable to set the above time to at least 1 second.
[0025]
Next, the abnormal number receiving process (step S6) shown in FIG. 2 will be described in detail with reference to FIG. If the caller number is the abnormal number registered in step S510 of FIG. 3, control unit 10 first determines whether or not this telephone is immediately set to off-hook (step S61).
[0026]
Then, when the immediate off-hook setting is performed (step S61: Yes), it is determined whether or not the automatic immediate disconnection setting is performed (step S62). When the automatic immediate disconnection setting is performed (step S62: Yes). ), Controlling the incoming call control section 4 to go on-hook (step S611) immediately after the off-hook (step S610), and to notify the user that there is an incoming call from the abnormal number and that the call was automatically immediately cut off (step S612). ).
[0027]
As can be seen from the above description, the automatic immediate disconnection is one of the measures to be taken when a nuisance call is received. When an incoming call is received, the user immediately goes off-hook and then immediately goes on-hook. By making this setting, it is possible to immediately connect the telephone number to the number registered as an abnormal number before disconnecting the telephone number, and to generate a charge for the caller.
[0028]
On the other hand, if there is an immediate off-hook setting but no automatic immediate off setting (step S61: Yes, step S62: No), the control unit 10 controls the incoming call control unit 4 to go off-hook (step S63). The timer 8 is instructed to start the timer 8 (step S64). In parallel with the time measurement by the timer 8, an automatic response message prepared in advance (such as "calling now") is transmitted to the transmission source (step S65).
[0029]
The timer control section 7 stops the timer 8 when a preset time has elapsed, and notifies the control section 10 of the fact that the time has elapsed. If the caller does not abandon the call until the notification from the timer control unit 7 is received (step S66: No), the control unit 10 notifies the user of an incoming call, for example, sounds a ringtone (step S67). ), The caller's telephone number is stored in the incoming call history in the RAM 5 (step S68), and the incoming call control section 4 is controlled to perform the incoming call processing as usual (step S69).
[0030]
On the other hand, if the calling party abandons the calling within the above time (step S66: Yes), the control unit 10 controls the incoming call control unit 4 to make it go on-hook (step S611) and informs that there is an incoming call from the abnormal number. The user is notified (step S612).
[0031]
If the immediate off-hook setting has not been immediately performed (step S61: No), the control unit 10 does not perform any other measures, for example, does not ring the caller (no sound), and goes off-hook until the caller stops calling. It is determined whether or not there is a setting such as not to perform (step S613). If there is such a setting (step S613: Yes), a process according to the setting is performed (step S614), and the fact that there is an incoming call from the abnormal number is performed. Is notified to the user (step S615).
[0032]
If no setting has been made for the abnormal number (step S613: No), the process proceeds to step S67, where a normal incoming call such as a ring tone sounds as in the case where there is an incoming call from a telephone number that is not an abnormal number. An incoming call process is performed (steps S67 to S69).
[0033]
As described above, according to the incoming call control function of the telephone according to the present invention, if an incoming call is made from an unregistered telephone number or a telephone number that has been previously received and has been immediately disconnected, the call is transmitted for a predetermined time or more. Since the incoming call is notified only when the caller does not hang up, it is possible to discriminate whether the first incoming number is a call from a person who really wants to talk or a nuisance call that is not willing to talk. As a result, the user at the destination can be released from the troublesome receiving operation associated with the nuisance call, and can also avoid troubles such as "one-way call" with an unscrupulous trader.
[0034]
In addition, even if a number is registered as an abnormal number, as long as the call from an unregistered number is not made, the caller will wait for a predetermined time to determine whether or not to abandon the call, as in the case of a call from an unregistered number, unless automatic immediate disconnection is set. The presence or absence can be checked again. On the other hand, when the automatic immediate cut-off setting is made, it is possible to immediately charge the other party of a malicious nuisance call such as so-called "one-cut", which has the effect of eliminating evil traders.
[0035]
In the above-described embodiment, a special registration work by the user is unnecessary by automatically registering the number of the abandoned call in an abnormally early state such as “one-ring” in the memory, but the user is required to perform a specific registration operation. Of course, the telephone number may be individually registered as an abnormal number. It does not matter whether the newly entered telephone number is registered as an abnormal number or the already registered telephone number (normal telephone number) is registered as an abnormal number.
[0036]
Further, the time measured by the timer 8 may be arbitrarily set by operating the operation unit 2 by the user. Recently, not only “one-cut”, but also “two-cut”, which sounds the ringtone twice to cut it, so it is possible to freely set and change the waiting time until an incoming call notification in this way, Can respond to unwanted forms of unwanted calls.
