Description

  The present invention relates to a portable communication terminal device having a function of notifying a missed call, a missed call notification method, and a missed call notification program.

  The mobile communication terminal device has a function of notifying the user of a missed call when the user does not respond to an incoming call or mail. In general, when it is not determined that the user has confirmed the notification of the missed call, the mobile communication terminal device re-notifies the missed call. When the mobile communication terminal device re-notifies the user of a missed call, the re-notification is repeated at regular intervals, or when the user touches the mobile communication terminal device or performs a specific operation.

  However, for example, when the user is away from the mobile communication terminal device, the user may notice the re-notification even if a missed call is re-notified by ringing a ring tone or vibrating the vibrator at regular intervals. Is low and consumes useless operating current. Further, for example, when re-notification is performed when the mobile communication terminal device is touched, even if the user places the mobile communication terminal device near the user, there is a possibility that a confirmation delay of the user's missed call may occur.

  There is a method of estimating the situation where the mobile communication terminal device is placed and re-notifying a missed call according to the estimated situation (see, for example, Patent Documents 1 and 2). In the mobile communication terminal device described in Patent Document 1, vibration of the mobile communication terminal device is detected, and the missed call re-notification interval is changed by comparing the detected vibration magnitude with a threshold value. Further, in the portable wireless device described in Patent Document 2, environmental data is detected by a vibration sensor, and the frequency of re-notification of a missed call is changed by comparing the detection result with a threshold value.

  However, in the portable communication terminal device described in Patent Document 1 and the portable wireless device described in Patent Document 2, it is conceivable that the user may not be notified of a missed call that is easy to notice quickly and has little waste.

  For example, when the user does not carry the mobile communication terminal device described in Patent Document 1, but is in the vicinity of the user, vibration is not detected, so the interval of missed call re-notification increases. When the mobile communication terminal device is in the vicinity of the user, it is considered that the user is easily aware of the missed call notification, but if the missed call re-notification interval is increased, a missed call confirmation delay occurs. There is a risk.

  For example, when the user leaves the portable wireless device described in Patent Document 2 for a long time, vibration is not detected, so the frequency of missed call re-notification increases. Actually, the user may not exist in the vicinity of the mobile wireless device, and increasing the frequency of re-notification may lead to wasteful power consumption.

  Therefore, the present invention suppresses consumption of operating current due to useless missed call notification when performing missed call re-notification, and enables a mobile communication terminal device, missed call notification method, and missed call notification capable of realizing power saving control. The purpose is to provide a program.

  The missed call notification method according to the present invention detects when a state of the mobile communication terminal device changes beyond a predetermined level or when a situation change occurs when the environment of the mobile communication terminal device changes beyond a predetermined level. A situation change detection step, an operation history storage step that stores at least operation data indicating the latest point in time when the user operated the operation unit of the mobile communication terminal device in the operation history storage unit, and at least the latest detected in the situation change detection step It is determined that a missed call has occurred in a status history storage step for storing status data indicating the time of the situation change in the status history storage unit, a missed call determination step for determining whether a missed call has occurred, and a missed call determination step A difference between a determination time point at which the determination is performed and a time point indicated by operation data stored in the operation history storage unit, and A notification interval determining step for determining a notification interval, which is an interval for notifying the user that a missed call has occurred, according to a difference between a fixed time point and a situation change time point indicated by the situation data stored in the situation history storage unit; It is characterized by including.

Embodiment 1. FIG.
FIG. 1 is a block diagram showing a configuration of a first embodiment (Embodiment 1) of a mobile communication terminal device according to the present invention. The configuration of the first embodiment will be described with reference to FIG. A mobile communication terminal device 20 shown in FIG. 1 is a mobile phone, and includes an acceleration sensor 21, an illuminance sensor 22, a control unit 23, a speaker 24, a vibrator 25, a memory unit 26, an operation unit 27, and a display unit 28.

  The acceleration sensor 21 is a sensor that detects acceleration. The illuminance sensor 22 is a sensor that detects illuminance. The control unit 23 is connected to a plurality of components of the mobile communication terminal device 20, and acquires information and controls operations. The memory unit 26 stores various programs executed by the control unit 23, various setting information, and data. For example, the control unit 23 can be realized by a microcomputer that executes processing according to a program.

  The control unit 23 sequentially inputs a signal indicating acceleration from the acceleration sensor 21, and determines whether the mobile communication terminal device 20 is in a moving state or a stationary state. When the state of the mobile communication terminal device 20 changes, the control unit 23 stores data indicating the time at that time in the memory unit 26 as situation change information (situation history information). The control unit 23 may sequentially store the status change information in the memory unit 26, or may store only the latest status change information in the memory unit 26. Further, if the acceleration defined as being in a stationary state is 0 (relative value, not the absolute value of acceleration is 0), the degree greater than 0 is the detection condition at the time of the situation change. This corresponds to a predetermined degree.

  Further, the control unit 23 sequentially inputs a signal indicating from the illuminance sensor 22 and determines an illuminance change (brightness / darkness) around the mobile communication terminal device 20 in which the illuminance sensor 22 is installed. When the illuminance around the mobile communication terminal device 20 fluctuates more than a predetermined reference value, the control unit 23 stores data indicating the time in the memory unit 26 as situation change information. Further, the control unit 23 performs control of ringing of the speaker 24, vibration of the vibrator 25, and the like.

  The memory unit 26 also stores a program for displaying a history of missed calls, a program for determining the level of ease of noticing missed call notifications, and setting information for intervals for re-notifying missed calls.

  The operation unit 27 detects an input from the user via an input key or the like, and outputs an input signal indicating what kind of input has been made to the control unit 23. When the input signal is input, the control unit 23 stores data indicating the time at that time in the memory unit 26 as operation data (operation history information). The display unit 28 outputs information to the user via a display display or the like according to an output command from the control unit 23. Note that the control unit 23 may sequentially store the operation data in the memory unit 26, or may store only the latest operation data in the memory unit 26.

  The mobile communication terminal device according to the present invention determines to what extent the user is easily aware of the missed call notification as the “easy to notice level” and re-notifies the user of the missed call by a method according to the easily noticed level. To do. FIG. 2 is an explanatory diagram showing an example of the relationship between the level of ease of awareness, the assumed situation, and the missed call re-notification interval. FIG. 3 is a flowchart showing a flow of determining the level of ease of awareness shown in FIG. With reference to FIG. 2 and FIG. 3, an operation in which the mobile communication terminal device 20 according to the present embodiment determines an easy-to-see level and re-notifies the user of a missed call by a method according to the easy-to-read level. .

  First, in the mobile communication terminal device 20, the control unit 23 determines that a predetermined operation indicating that the user has confirmed the incoming call has not been performed after receiving an incoming call or e-mail from another information terminal. Sometimes it recognizes that a missed call has occurred. When a missed call occurs, the control unit 23 notifies the missed call by displaying the missed call history on the display unit 28.

  If the user does not perform a predetermined operation indicating that the missed call notification has been confirmed from the operation unit 27 or the like even after a predetermined time has elapsed since the missed call notification, the control unit 23 In order to perform re-notification of the missed call, the determination of the ease of noticing is started according to the flowchart shown in FIG.

  The control unit 23 refers to the operation history information stored in the memory unit 26 and performs any operation on the mobile communication terminal device 20 within a predetermined short time Th1 (for example, 3 seconds) in the past from the determination time. Whether or not has been performed is determined (step S301). Here, the operation means an operation such as pressing of a key button by the operation unit 27, but when the mobile communication terminal device 20 is a deformable form such as a foldable mobile communication terminal device, a folded portion The opening / closing operation and the like may also be included in the operation as a determination target.

  If it is determined that the operation has been performed within the time Th1 (within 3 seconds), it is estimated that the mobile communication terminal device 20 is in the state of the user's hand during the operation by the user or immediately after the operation. That is, it is estimated that the user is very aware of missed call re-notification. Therefore, the control unit 23 determines that the level of ease of awareness is Lv1 as the level corresponding to the assumed situation shown in FIG. 2 (step S302).

  When it is determined that the operation has not been performed within the time Th1 (within 3 seconds), the control unit 23 refers to the operation history information stored in the memory unit 26, and at a time longer than Th1. It is determined whether or not any operation has been performed on the mobile communication terminal device 20 within a predetermined time Th2 (for example, 1 minute), which is a short time (step S303).

  When it is determined that the operation has been performed within the time Th2 after the time Th1 (within 1 minute to 3 seconds before), the mobile communication terminal device 20 that has been operated by the user until recently is displayed. Presume that the user is in the vicinity. That is, although it is inferior to the situation of Lv1 noticing easily for the missed call re-notification, it is presumed that the user is easily noticed to some extent. Therefore, the control unit 23 determines that the level of ease of awareness is Lv2 as the level corresponding to the assumed situation shown in FIG. 2 (step S304).

  When it is determined that the operation has not been performed within the time Th2 (within 1 minute), the control unit 23 refers to the situation history information stored in the memory unit 26 and performs a short predetermined time Th3 ( For example, it is determined whether or not the mobile communication terminal device 20 is switched from the moving state to the stationary state within 5 seconds (step S305).

  When it is determined that the mobile communication terminal device 20 has moved to the stationary state within the time Th3 (within 5 seconds), it is estimated that the mobile communication terminal device 20 has been stationary with the user moving. That is, although it is inferior to the situation of Lv1 noticing easily for the missed call re-notification, it is presumed that the user is easily noticed to some extent. Therefore, the control unit 23 determines that the level of ease of awareness is Lv2 as the level corresponding to the assumed situation shown in FIG. 2 (step S304).

  When it is determined that the switch has not been switched to the stationary state within the time Th3 (within 5 seconds), the control unit 23 refers to the situation history information stored in the memory unit 26 and refers to the short predetermined time Th4 ( For example, it is determined whether or not the illuminance around the mobile communication terminal device 20 has changed more than a predetermined reference value within 8 seconds (step S306).

  In addition, although the control part 23 sets the time which satisfy | fills the relationship of Th1 <Th2 as Th1 and Th2, you may set arbitrary time as Th3 and Th4. It is more effective to determine a value suitable for the situation to estimate the time set for Th1 to Th4 by opinion evaluation or the like.

  FIG. 4 is a schematic diagram when the folding portable communication terminal device in an open state is viewed from the front. The illuminance sensor 22 shown in FIG. 4 is installed in a place where the illuminance at the top can be detected when the fold is opened. FIG. 5 is a schematic diagram when the foldable portable communication terminal device shown in FIG. 4 in a closed state is viewed from the front. The illuminance sensor 22 can detect external illuminance even when the folding is closed. As described above, when the mobile communication terminal device 20 has a deformable form such as a foldable mobile communication terminal device, the illuminance sensor 22 is mounted at a position where the ambient illuminance can be detected regardless of the shape. To be considered.

  In step S306, when it is determined that the surrounding illuminance has changed more than a predetermined reference value within the time Th4 (within 8 seconds), the user places the mobile communication terminal device 20 in and out of a pocket or bag. The illuminance has changed greatly due to the above, or the illuminance has changed greatly by turning on / off the electricity in the room while the user has left the mobile communication terminal device 20 for a certain period of time or more. It is presumed that there is a light / dark change around 20 and that it is in a short time. In other words, there is a possibility that the user is still present around the mobile communication terminal device 20, and it is inferior to the situation of the Lv1 noticeability for the re-notification of the missed call, but to some extent the user is easily noticed. Presume that there is. Therefore, the control unit 23 determines that the level of ease of awareness is Lv2 as the level corresponding to the assumed situation shown in FIG. 2 (step S304).

  When it is determined that the ambient illuminance has not changed significantly within the time Th4 (within 8 seconds), the control unit 23 determines that the mobile communication terminal device 20 is currently moving based on the signal output from the acceleration sensor 21. It is determined whether or not it is in a state (step S307).

  If it is determined in step S307 that the current state is the moving state, the controller 23 determines that the illuminance around the mobile communication terminal device 20 is currently lower than a predetermined reference based on the signal output from the illuminance sensor 22. It is determined whether it is high (bright) (step S308).

  If it is determined in step S308 that the ambient illuminance is higher (brighter) than a predetermined reference, it is estimated that the user is moving the mobile communication terminal device 20 out of a pocket or bag. That is, it is estimated that the user is more likely to notice the missed call re-notification than the state where the mobile communication terminal device 20 is put in a pocket or bag. Therefore, the control unit 23 determines that the level of ease of awareness is Lv2 as the level corresponding to the assumed situation shown in FIG. 2 (step S304).

  If it is determined in step S308 that the ambient illuminance is not higher (darker) than the predetermined reference, it is estimated that the user is moving the portable communication terminal device 20 in a pocket or bag. That is, it is presumed that the user is less likely to notice the missed call re-notification than when the mobile communication terminal device 20 is taken out of the pocket or bag. Therefore, the control unit 23 determines that the level of ease of awareness is Lv3 as the level corresponding to the assumed situation shown in FIG. 2 (step S309).

  If it is determined in step S307 that the mobile communication terminal device 20 is not currently in a moving state, the mobile communication terminal device 20 has not been operated for a certain period of time, is stationary, and has no change in ambient illuminance, and there is a user in the surroundings. It is presumed that it has been left for a certain period of time. That is, it is estimated that the user is difficult to notice the missed call re-notification. Therefore, the control unit 23 determines that the level of ease of awareness is Lv4 as the level corresponding to the assumed situation shown in FIG. 2 (step S310).

  When the level of ease of awareness is determined in the determination process shown in steps S301 to S310, the control unit 23 performs control such as ringing a ring tone from the speaker 24 or vibrating the vibrator 25, and the like. Re-notify the user of missed calls. In addition, the control unit 23 sets the determined noticeability level and the re-notification notification interval corresponding to the noticeability level in the memory unit 26. The noticeability level Lvn (n: 1 to 4) corresponds to the notification interval Tn. As shown in FIGS. 1 and 2, the notification interval is T1 <T2 <T3 <T4. The notification interval decreases as the level of ease of awareness decreases (the value of n decreases), that is, the user is more likely to notice missed calls.

  The control unit 23 performs the recognizing level determination process again after a time corresponding to the notification interval of the re-notification set in the memory unit 26 has elapsed after performing the re-notification of the missed call. In addition, when the level of ease of awareness is set to Lv2, Lv3, or Lv4, the control unit 23 performs the process of determining the level of ease of awareness again when detecting some operation of the mobile communication terminal device 20. To do. When the easy-to-see level is set to Lv3, the control unit 23 performs the easy-to-read level determination process again when it is determined that the mobile communication terminal device 20 is in a stationary state. When the level of ease of awareness is set to Lv4, the control unit 23 determines the level of ease of awareness again when the mobile communication terminal device 20 determines the movement state or determines the change in illuminance. Perform the judgment process.

  When the user performs a predetermined operation for confirming the missed call history in response to the missed call re-notification from the control unit 23, the control unit 23 stops the operation of repeating the notice level determination process, Ends re-notification of incoming calls.

  In such a mobile communication terminal device, when notifying a user that a missed call has been received, the current mobile communication terminal device is estimated from acceleration information, illuminance information, etc. Determine the level of ease of noticing the incoming notification. Since the mobile communication terminal device changes the interval for re-notifying missed calls according to the level of ease of awareness, for example, in situations where it is estimated that the user is unlikely to be noticed, the re-notification interval is set longer than usual. By notifying, it is possible to suppress waste that is frequently re-notified, and to reduce the operating current and realize power saving control. On the other hand, for example, in a situation that is estimated to be easily noticed by the user, it is possible to expect the effect of promptly recognizing the missed call by notifying the user with the re-notification interval set to be shorter than or equal to the normal interval . In addition, even if the user leaves the mobile communication terminal device, the missed call is re-notified at an appropriate interval, so that the missed call confirmation can be prevented from being delayed.

Embodiment 2. FIG.
A second embodiment (embodiment 2) of a mobile communication terminal device according to the present invention will be described. The mobile communication terminal device of the second embodiment includes a human sensor instead of the illuminance sensor in the mobile communication terminal device of the first embodiment. The configuration of the second embodiment is the same as the configuration of the first embodiment shown in FIG. 1 except that the illuminance sensor 22 shown in FIG. 1 is replaced with a human sensor.

  The human sensor is a sensor that detects the presence of a moving object such as a human (hereinafter referred to as a human being) around the human sensor using infrared rays, ultrasonic waves, visible light, or the like. Based on the signal output from the human sensor, the control unit 23 sequentially determines whether or not a human is present around the mobile communication terminal device. When the human sensor outputs a signal indicating the presence of the human, Data indicating the time is stored in the memory unit 26 as status history information.

  FIG. 6 is a flowchart showing a flow of determining the level of ease of awareness shown in FIG. With reference to FIG. 2 and FIG. 3, the operation of the mobile communication terminal device of the second embodiment determining the ease of noticing and re-notifying the user of missed calls by a method according to the level of easy to notice will be described. To do.

  In the mobile communication terminal device of the second embodiment, the processing unit 23 determines the part of Lv1 and Lv2 that are easy to notice (steps S601 to S605) in the first embodiment (FIG. 3). Steps S301 to S305).

  If it is determined in step S605 that the mobile communication terminal device has not switched to the stationary state within the time Th3 (within 5 seconds), the control unit 23 sets the short predetermined time Th5 (for example, 8 seconds). It is determined whether or not the presence of a human is detected around the mobile communication terminal device (step S606). The control unit 23 refers to the situation history information stored in the memory unit 26 and performs the determination in step S606. Note that the control unit 23 may set an arbitrary time as the time Th5. It is more effective to determine a value suitable for the situation to estimate the time set to Th5 by opinion evaluation or the like.

  If it is determined in step S606 that the presence of a human being is detected within the time Th5 (within 8 seconds), the user has not performed an operation within the time Th1 and within the Th2 (within 1 minute). Even if it exists, it estimates that it exists in the vicinity of a portable communication terminal device. That is, it is estimated that the user is easily aware of the missed call re-notification. Therefore, the control unit 23 determines that the level of ease of awareness is Lv2 as the level corresponding to the assumed situation shown in FIG. 2 (step S604).

  If it is determined that the presence of a human being is not detected within the time Th5 (within 8 seconds), the control unit 23 determines whether or not the mobile communication terminal device is currently moving (step S607). ).

  If it is determined in step S607 that the user is currently moving, the user has not been detected from the human sensor within the time Th5 (within 8 seconds), but infrared light is not transmitted between the mobile communication terminal device and the user. In the case of being blocked, the human sensor may not be able to detect even if the user is nearby, so it is estimated that the user is moving with the mobile communication terminal device. That is, it is estimated that the user is close but it is difficult to notice the missed call re-notification. Therefore, the control unit 23 determines that the level of ease of awareness is Lv3 as the level corresponding to the assumed situation shown in FIG. 2 (step S609).

  If it is determined that the mobile communication device is not currently in a moving state, the mobile communication terminal device is in a state in which there is no operation for a certain period of time, a stationary state, and no human sensor response (no operation for one minute or more and a stationary state for five seconds or more) And there is no human sensor response for 8 seconds or more), and it is estimated that there is no user in the surroundings and the user is left for a certain time or longer. That is, it is estimated that the user is difficult to notice the missed call re-notification. Therefore, the control unit 23 determines that the level of ease of awareness is Lv4 as the level corresponding to the assumed situation shown in FIG. 2 (step S610).

  When the level of ease of recognition is determined in the determination processing shown in steps S601 to S610, the control unit 23 performs control such as ringing a ring tone from the speaker 24 or vibrating the vibrator 25. Re-notify the user of missed calls. In addition, the control unit 23 sets the determined noticeability level and the re-notification notification interval corresponding to the noticeability level in the memory unit 26. Similar to the first embodiment, the ease-of-notice level Lvn (n: 1 to 4) corresponds to the notification interval Tn. The notification interval is T1 <T2 <T3 <T4 as shown in FIGS. The notification interval decreases as the level of ease of awareness decreases (the value of n decreases), that is, the user is more likely to notice missed calls.

  The control unit 23 performs the same process as the first embodiment for the user control unit 23 to perform the recognizing level determination process again, the process for terminating the missed call re-notification, and the like.

  In such a mobile communication terminal device, when notifying the user that there was a missed call, the current mobile communication terminal device is placed from the signal output from the acceleration sensor 21 or the signal output from the human sensor. The level of ease of noticing the user's missed call notification is determined by estimating the situation. The mobile communication terminal device uses the presence sensor to determine the presence level of human beings to determine the level of ease of awareness, thereby determining whether the mobile communication terminal device is near the user with higher reliability than the illuminance sensor. Can be determined. Note that the effect of re-notifying a missed call according to the level of ease of awareness is the same as the effect of the mobile communication terminal device of the first embodiment.

  In the mobile communication terminal device of the second embodiment, the human sensor may be replaced with a microphone, or the human sensor and the microphone may be used in combination. Whether or not there is a person (user) in the surroundings by collecting ambient noise conditions using a microphone and analyzing sound data collected by the control unit 23 using a program stored in the memory unit 26 Can be determined.

Embodiment 3. FIG.
A third embodiment (embodiment 3) of a mobile communication terminal device according to the present invention will be described. In the first and second embodiments, when the missed call is re-notified to the user, the control is performed to switch the re-notification interval according to the user's level of notice of the missed call. In the embodiment, control is performed to change the ring volume or the vibration amount (amplitude) of the vibrator when re-notifying in accordance with the level of ease of awareness. The configuration of the third embodiment is the same as either the configuration of the first or second embodiment.

  In the third embodiment, if the user does not confirm the missed call even after a predetermined time has elapsed since the missed call notification, the control unit re-notifies the missed call. Determine the level of ease of awareness to do so.

  FIG. 7 is an explanatory diagram showing an example of the relationship between the level of ease of awareness, the assumed situation, and the missed call notification means. The level of ease of awareness and the assumed situation are the same as those shown in FIG. 2, but the notification means for missed call notifications corresponding to each level is different.

  In the third embodiment, the process of determining the ease of noticing the user's missed call notification is the process of determining the ease of noticing the user's missed call notification in the first or second embodiment (see FIG. 3). This is the same as steps S301 to S310 or steps S601 to S610 in FIG. However, instead of the relationship between the easy-to-see level shown in FIG. 2 and the notification interval of the missed call notification, the relationship between the easy-to-see level and the missed call notification means shown in FIG. 7 is used.

  When determining the noticeability level, the control unit sets re-notification of a missed call according to the correspondence between the noticeability level and the notification means shown in FIG. As notification means corresponding to the easy-to-recognize levels Lv1 to Lv4, V1 to V4 are set as the ringing volume, and P1 to P4 are set as the vibrator vibration amount. The ring volume is set as V1 <V2 <V3 <V4, and V1 has the lowest volume. The vibrator vibration amount is set as P1 <P2 <P3 <P4, and P1 has the smallest vibration amount. Generally, the smaller the incoming ring volume and the vibrator vibration amount are, the smaller the larger one is, the less noticeable to the user, but the current consumption can be reduced.

  In such a mobile communication terminal device, it is possible to re-notify the user of a missed call by changing the volume of the incoming call volume and the amount of vibration of the vibrator according to the level of ease of awareness. The user can be notified of missed calls even if the ring tone is not set. Also, in a situation where it is difficult for the user to notice re-notification of a missed call, by reducing the ring volume and vibrator vibration amount, current consumption can be suppressed, and power saving control can be realized.

  Note that the notification means may be able to select either a ringtone or vibrator vibration. Furthermore, the notification interval change corresponding to the noticeability level shown in the first or second embodiment may be selected together with the notification unit of the third embodiment.

  In such a portable communication terminal device, for example, by letting the user select the notification means, it is possible to realize re-notification of a missed call by the notification means suitable for the user's environment.
