[0009] Hereinafter, a mobile communication terminal system according to an embodiment of the present invention will be described with reference to the drawings. In the embodiments, components having substantially the same functions and configurations are designated by the same reference numerals, and redundant description will be omitted. [Example]

[0010] (First Example) 1 is a schematic diagram illustrating an example of the configuration of a mobile communication terminal system 100 according to a first embodiment. The mobile communication terminal system 100 includes a management center device 10 and a mobile communication terminal 101, such as a smartphone, that can communicate with the management center device 10 via a network NW.

[0011] (network) The network NW that communicatively connects the mobile communication terminal 101 and the management center device 10 is a mobile phone network (LTE (Long Term Evolution) or 4G (fourth generation mobile communication standard) or 5G (fifth generation mobile communication standard)), an IP (Internet Protocol) network, or a public switched telephone network. In addition, the network NW may include, for example, a public line network such as a satellite communication network, various WANs (Wide Area Networks), dedicated line networks such as VoPNs (Voice over Packet Networks), and individual LANs (Local Area Networks).

[0012] The network NW and the mobile communication terminal 101 may be connected to the Internet by communication conforming to the Wi-Fi (registered trademark) standard via an access point AC of a WAN or LAN.

[0013] (Mobile communication terminal 101) FIG. 2 is a schematic diagram showing an example of the configuration of a smartphone 101, which is a mobile communication terminal in this embodiment.

[0014] The smartphone 101 includes, as hardware, for example, a communication function unit 101a, a touch panel 101b (image display device), a clock 101c, a microphone 101d, a speaker 101e (sound generating device), a vibrator 101f (vibration generating device), a camera 101g, a GPS device 101h for detecting the current position, a gyro sensor 101i for detecting angular velocity, a geomagnetic sensor 101j for detecting magnetism, a proximity sensor 101k for detecting the distance from the touch panel and an illuminance sensor 101l for detecting the brightness thereof, an acceleration sensor 101m for detecting acceleration, and an atmospheric pressure sensor 101n for detecting atmospheric pressure, as well as a control unit 101o.

[0015] The communication function unit 101a includes an LTE (Long Term Evolution), 4G, or 5G communication function unit that communicates between the device itself and other devices, a wireless function unit that performs close-proximity wireless communication between the device itself and other devices when they are close to each other (for example, a Wi-Fi (registered trademark) standard communication function unit, a Bluetooth (registered trademark) standard BLE (Bluetooth Low Energy) communication function unit), and their respective antennas, and is used for voice calls and data communication.

[0016] The touch panel 101b is an operation and display unit for interfacing with the user, and functions as an operation means and a notification means for the user. The speaker 101e and the vibrator 101f also function as a notification means.

[0017] The GPS device 101h, the gyro sensor 101i, the acceleration sensor 101m, and the atmospheric pressure sensor 101n are motion sensor means that function as part of a motion time acquisition means for acquiring the time when the smartphone 101 moves or shakes. The gyro sensor 101i, the acceleration sensor 101m, and the atmospheric pressure sensor 101n of the motion sensor means detect the motion time when the smartphone 101 changes its attitude, such as when it is shaken while being carried in a range of movement that cannot be detected by the GPS device 101h.

[0018] The control unit 101o controls the communication function unit 101a and other operating devices, and receives and processes signals from the GPS device 101h and other sensors. The control unit 101o is a computer device that includes a CPU (Central Processing Unit) and a storage unit such as a RAM (Random Access Memory) (not shown), and controls the overall operation of the communication terminal, including processing, using the CPU in accordance with various software programs stored in the storage unit. The CPU executes abnormality notification processing in accordance with various application software programs installed in the storage unit, for example, an abnormality notification application software program.

[0019] The abnormality notification application software program installed in the smartphone 101 is deployed in the storage unit, and the program causes the CPU to have the following functional units: (1) a location information acquisition unit 21; (2) a motion time acquisition unit 22; (3) Operation monitoring section 23 (4) a timing unit 24; (5) a detection notification unit 25; (6) Function as the transmitting unit 26.

[0020] Each functional unit of the smartphone 101 functions as follows: The location information acquisition unit 21, the motion time acquisition unit 22, the operation monitoring unit 23, and the clock unit 24 are assigned individual storage areas (not shown) for storing and saving their respective setting data and detection data.

[0021] (Location information acquisition unit 21) The location information acquisition unit 21 periodically acquires location information (GPS information) based on a signal received from the GPS device 101h and records it in the recording area. In this case, the location information acquisition unit 21 determines whether the terminal is moving based on whether the location information has changed, and acquires movement information (motion time at which the location of the smartphone 101 has changed).

[0022] When the location information acquisition unit 21 detects movement based on location information from the GPS device 101h, it stores the time in the recording area as the last use time linked to the location information.

[0023] (Motion time acquisition unit 22) The motion time acquisition unit 22 acquires the motion time at the time when the attitude of the smartphone 101 changes, such as shaking caused by carrying it in a range of movement that cannot be detected by the GPS device 101h, using the motion sensor means (gyro sensor 101i, acceleration sensor 101m, and atmospheric pressure sensor 101n), and records the motion time in the recording area.

[0024] That is, when the motion time acquisition unit 22 detects shaking of the smartphone 101 while it is being carried, it stores that time in the recording area as the last use time linked to the location information.

[0025] (Operation monitoring unit 23) The operation monitoring unit 23 detects whether the smartphone 101 has been operated.

[0026] When the operation monitoring unit 23 detects an operation on the smartphone 101, the operation monitoring unit 23 stores the time in the recording area as the last use time linked to the location information.

[0027] As described above, when the location information acquisition unit 21, the motion time acquisition unit 22, and the operation monitoring unit 23 each confirm the use (movement, shaking) of the smartphone 101, they each store the detection data and the last time of use.

[0028] (Timekeeping section 24) The clock unit 24 holds two types of notification time widths: one is a confirmation notification time width, which is a time width for sending a notification to the smartphone 101 to confirm the safety of the user, and the other is an abnormal time width related to safety, which is a time width during which the safety of the user is in doubt and for which an abnormality should be notified to the management center device 10 of the management center (a predetermined set time width excluding general sleeping time or the general sleeping time of the user, which is assumed to be within the so-called "72-hour wall", for example). For example, if an abnormality notification is issued when the smartphone 101 is not operated for 24 hours and a confirmation notification is issued to the smartphone 101 one hour before that, 23 hours, have elapsed, 23 hours and 24 hours are held as the set values.

[0029] (Detection notification unit 25) The detection notification unit 25 checks whether the current time exceeds two time ranges set in the timing unit 24 from the last usage time stored in the location information acquisition unit 21, motion time acquisition unit 22, and operation monitoring unit 23, and if the confirmation notification time range is exceeded, it activates the transmission unit 26 and sends a confirmation notification to the smartphone 101, and if the abnormal time range is exceeded, it activates the transmission unit 26 and sends an abnormality notification to the management center device 10 (notifying the last usage time and location information at the last usage time).

[0030] When the time set in the timer 24 (confirmation notification time) arrives, the detection notification unit 25 notifies the user via the touch panel 101b to confirm that no operation has been performed on the smartphone 101, but the speaker 101e and the vibrator 101f can also function as notification means. If an operation is performed in response to this confirmation notification, the operation monitoring unit 23 records that time as the last use time.

[0031] If no operation is performed in response to this confirmation notification and the abnormal time width set in the timer unit 24 is exceeded, the detection notification unit 25 transmits the position information to the management center device 10 as an abnormality notification.

[0032] In this way, the detection notification unit 25 periodically checks whether the current time exceeds the two time ranges set in the timing unit 24 from the last usage time stored in the location information acquisition unit 21, the motion time acquisition unit 22, and the operation monitoring unit 23.

[0033] (Transmitter 26) The transmission unit 26 periodically transmits the last use time, the location information, and the time set in the clock unit 24 as periodic information (periodic notification) to the management center device 10. Furthermore, when the detection notification unit 25 detects that no operation has been performed for a certain period of time, the transmission unit 26, in response to a command from the detection notification unit 25, notifies the management center device 10 of an abnormality.

[0034] (Management center device 10) 1, the management center device 10 is a computer device that functions as a server of the management center and can acquire time information, and has a CPU 11, a storage device 12, an input unit 13 and an output unit 14 that are interfaces for administrators and the like, and a communication unit 15, all of which are connected to each other by an internal bus (not shown). Input information and the like is acquired by the management center device 10 via the input unit 13 and the communication unit 15.

[0035] The storage device 12 may be, for example, a RAM, a hard disk drive (HDD), a solid state drive (SSD), or flash memory, which stores various programs and data and serves as a work area for the CPU 11. The input unit 13 may be a keyboard, mouse, touch panel, numeric keypad, etc. for inputting data. The output unit 14 may be a display, touch panel, etc. for displaying the status to an administrator or the like who inputs data. The communication unit 15 communicates with the network NW and sends and receives data. The input unit 13 and output unit 14 may also be an external device, such as a universal serial bus (USB) to which a recording medium can be connected.

[0036] The overall operation of the management center device 10 is controlled by a CPU 11 that follows the program of operating system (OS) software installed in the storage device 12. The CPU 11 executes information processing in accordance with various application software programs stored in the storage device 12, for example, application software for information processing.

[0037] The installed application software for information processing is developed in the storage device 12, and the CPU 11 operates the following functional units: (1) Information Registration Department PKP; (2) a reception information recording unit FCT; (3) Function as the reporting unit FJP.

[0038] The information registration unit PKP holds contact information that has been registered in advance. For example, a contact information for notifying an abnormality is registered in advance in the information registration unit PKP via the smartphone 101.

[0039] The communication unit 15 receives the location information of the smartphone 101, the predetermined set time range (abnormal time range) set in the timing unit 24, and the last usage time as periodic information or abnormality notification information, and the received information recording unit FCT stores the information sent and received from the smartphone 101.

[0040] When the reporting unit FJP receives the abnormality notification information, it reports the last use time and the location information at the last use time to the contact person based on the abnormality notification information.

[0041] Furthermore, the reporting unit FJP detects whether reception of periodic information has ceased, i.e., whether the reception interval is normal. When reception of periodic information from the smartphone 101 has ceased (abnormal reception interval), the reporting unit FJP detects whether the current time has exceeded a predetermined set time interval (abnormal time interval) from the last use time based on the periodic information stored in the storage device 12 immediately before the interruption, and if the predetermined set time interval has been exceeded, reports the last use time and the location information at the last use time to the contact.

[0042] In this way, when the reporting unit FJP receives an abnormality notification from the smartphone 101, or when communication from the smartphone 101 is lost, the reporting unit FJP can report to the registered contacts.

[0043] (Smartphone 101 Operation Explained) The smartphone 101 executes the operations of sending periodic notifications and abnormality notifications to the management center device 10 in accordance with the flow shown in FIG.

[0044] The timer is set in the timing unit 24 and timing starts (step S1). It is assumed that predetermined settings (GPS device on, motion sensor means on, distance measurement unit on, etc.) have been made in the smartphone 101 before the timer is set. Furthermore, it is assumed that two types of time widths, a confirmation notification time width and an abnormal time width, have been set and saved in the timing unit 24.

[0045] The location information acquisition unit 21 periodically acquires GPS information (location information) from the GPS device 101h (step S2).

[0046] In this case, the location information acquisition unit 21 detects whether the terminal is moving from the change in the location information (step S3), and if the terminal is moving (step S3: Y), updates and saves the time and location information for each piece of location information (step S4).

[0047] After step S4 of updating and saving, or if there is no change in the GPS information (step S3: N), the motion time acquisition unit 22 detects the presence or absence of shaking motion due to carrying within a range that cannot be detected by movement using the GPS device 101h using the motion sensor means (gyro sensor 101i, acceleration sensor 101m and atmospheric pressure sensor 101n) (step S5), and if motion is detected (step S5: Y), links the motion time to the location information and updates and saves it as the last usage time (step S6).

[0048] After step S6 of updating and saving, or if there is no change in the shaking motion (step S5: N), the operation monitoring unit 23 detects operation of the smartphone 101 such as the touch panel 101b or other switches (step S7), and if an operation is detected (step S7: Y), the operation time is linked to the location information and updated and saved as the last usage time (step S8).

[0049] After step S8 of updating and saving, or if there is no operation (step S7: N), the transmission unit 26 detects whether there has been a change in the updated and saved motion time or the last use time at the time of operation within a certain period of time (step S9), and if there has been no change (step S9: Y), returns to step S1 of setting (resetting) the timer.

[0050] If there is no change in the last usage time (step S9: N), the transmitting unit 26 transmits (periodic notification) periodic information (location information of the smartphone 101, the predetermined set time range (abnormal time range) set in the timing unit 24, and the last usage time) to the management center device 10 (step S10).

[0051] After transmitting to the management center device 10, the detection notification unit 25 checks whether the current time exceeds the confirmation notification time range set in the timing unit 24 from the last time of use (step S11), and if the confirmation notification time range has been exceeded (step S11: Y), it operates the transmission unit 26 and sends a confirmation notification to the smartphone 101, for example via the touch panel 101b (step S12).

[0052] If the confirmation notification time has not passed (step S11: N), the process returns to the GPS information acquisition step S2.

[0053] After the confirmation notification to the management center device 10, a check is made to see if an operation has been performed in response to this notification (step S13). If an operation has been performed via the touch panel 101b, for example, the timer is set (reset) and the process returns to step S1 so that the time is recorded in the operation monitoring unit 23 as the last usage time.

[0054] If no operation is performed in response to this confirmation notification (step S13: N), the detection notification unit 25 checks whether the current time exceeds the abnormal time range set in the timing unit 24 from the last use time (step S14), and if it exceeds the abnormal time range (step S14: Y), it operates the transmission unit 26 and transmits abnormal information (location information of the smartphone 101, last use time) to the management center device 10 as an abnormality notification to the management center, and then terminates (step S15).

[0055] If the abnormal time width has not been exceeded (step S14: N), the process returns to the GPS information acquisition step S2, and the position information acquisition unit 21 continues to periodically acquire GPS information (position information) from the GPS device 101h.

[0056] (Explanation of the operation of the management center device 10) The management center device 10 executes the operation of notifying the contact person of an abnormality in accordance with the flow shown in Fig. 4. It is assumed that the contact person is registered in advance in the information registration unit PKP of the management center device 10.

[0057] The received information recording unit FCT of the management center device 10 stores the current date and time information for synchronization with the smartphone 101 (step S21).

[0058] The notification unit FJP detects whether the reception interval of communication with the smartphone 101 is normal (step S22), and if it is normal (step S22: Y), it detects whether it is a periodic notification of the smartphone 101's periodic information (smartphone 101's location information, a predetermined set time range (abnormal time range) set in the timing unit 24, and the last use time) (step S23), and if it is a periodic notification (step S23: Y), the information recording unit FCT saves the periodic information (step S24), returns to step S22, and continues receiving periodic notifications.

[0059] If the reception interval of communication with the smartphone 101 is abnormal (step S22: N), the reporting unit FJP detects whether or not the current time has exceeded a predetermined set time width (abnormal time width) from the last use time based on the periodic information stored in the storage device 12 immediately before the communication was interrupted (step S25), and if the abnormal time width has been exceeded (step S25: Y), the reporting unit FJP activates the transmitting unit 26 and reports the abnormality to the registered contacts (step S26). Also, in step S23 of detecting whether or not it is a periodic notification, even if the abnormal notification from the smartphone 101 is not a periodic notification (step S15 in FIG. 3), the reporting unit FJP reports the abnormality to the registered contacts and ends (step S26). (Explanation of effect) In this embodiment, not only is it possible to detect the absence of any operation for a certain period of time and movement using the GPS device 101h, but it is also possible to detect carrying over a distance that cannot be detected by the GPS device 101h by using a motion sensor.

[0060] In addition, by checking the time when the smartphone 101 does not send a notification to the management center device 10 on the management center device 10 side, it is possible to detect even when the smartphone 101 is no longer able to send a notification due to a dead battery or the like.

[0061] For these reasons, by increasing the content of detectable usage, it is possible to reduce false detections. Also, even if the smartphone 101 is broken or the battery is dead, the management center device 10 can detect the receipt of periodic information from the smartphone 101 and notify the registered destination.

[0062] Examples of the mobile communication terminal include the smartphone 101, as well as a tablet mobile communication terminal, a notebook personal computer (PC), a smart watch, and other mobile computer communication terminals equipped with a notification means.

[0063] (Second Example) In the first embodiment, the last usage time is used, which changes when the movement, operation, or shaking motion of the smartphone 101 that the user always carries is detected, while in the second embodiment, the system detects the user's movements, which can be detected by, for example, wireless earphones 3, which are wearable communication terminals that the user always wears and are paired with the smartphone 101, and reports the user's safety.

[0064] 5 and 6, the system of this embodiment is the same as that of the first embodiment except that, for example, wireless earphones 3 paired with a smartphone 101 are worn by a user and a distance measurement unit 27 is provided in the memory unit of the smartphone 101. This embodiment also enables the wearable communication terminal and the smartphone 101 to be used in conjunction with each other as an additional function.

[0065] (Wireless Earphones 3) Fig. 7 is a schematic diagram showing the external configuration of an example of a single-ear wireless earphone 3 worn by a user in this embodiment. Fig. 8 is a schematic diagram illustrating the interior of the wireless earphone 3.

[0066] The wireless earphone 3 has a driver unit 3a, which is a speaker such as a dynamic or balanced armature type, housed inside the outer shell, a printed circuit board 3b that drives the driver unit, an operation unit 3c that is attached to the outer surface and is an interface that can be operated manually by the user, and a power supply unit 3d, such as a secondary battery, that supplies power to the printed circuit board.

[0067] The printed circuit board 3b is mounted with a slave communication unit 32 and a processing control unit SoC.

[0068] The slave device communication unit 32 includes a wireless communication module including an antenna capable of communication according to the Wi-Fi (registered trademark) standard or the Bluetooth (registered trademark) standard with the communication function unit 101a of the smartphone 101. The antenna of the slave device communication unit 32 receives a detection value request signal from the smartphone 101 and transmits a response signal in response to the request signal.

[0069] The processing control unit SoC on the printed circuit board 3b of the wireless earphones 3 is a chip (system on a chip) that includes, for example, a DSP (Digital Signal Processor) and an MCU (Micro Control Unit) that are control units, a memory unit MEM such as RAM, such as a codec and flash memory that stores profiles, and integrates functions such as an A / D converter circuit and a D / A converter circuit. The MCU, which operates in accordance with a software program installed in the memory unit MEM, communicates with the smartphone 101 via near-field wireless communication and performs processing for sending and receiving data to and from the smartphone 101.

[0070] The driver unit 3a is connected to the D / A converter circuit. Upon receiving a predetermined signal from the smartphone 101, the MCU drives the driver unit 3a via the D / A converter circuit, enabling the wireless earphone 3 to generate sound and notification sounds. Upon receiving a command from the smartphone 101, the MCU causes the driver unit 3a to generate sound via the D / A converter circuit, enabling the status of the smartphone 101 to be notified by sound (such as a confirmation notification).

[0071] The wireless earphones 3 are wearable communication terminals that the user always carries, i.e., carries or wears. They communicate with the communication function unit 101a of the smartphone 101 shown in FIG. 6 using Bluetooth (registered trademark) or Wi-Fi (registered trademark) standards, and can measure the approximate distance between them from the smartphone 101 side. The distance measurement unit 27 of the smartphone 101 saves the time when the change in distance from the wearable communication terminal exceeds a predetermined value as the last use time. The distance measurement unit 27 can use the Wi-Fi RTT (round trip time) API for the Wi-Fi (registered trademark) standard, and can measure the mutual distance using Bluetooth RSSI or a received signal strength indicator for the Bluetooth (registered trademark) standard.

[0072] 6 is also assigned a separate storage area (not shown) for storing setting data and detection data, and stores the time when the distance from the wireless earphone 3 changes. When the smartphone 101 is using the wireless earphone 3, if a change in the distance between the communication function unit 101a of the smartphone 101 and the wireless earphone 3 is detected, that time is stored in the storage area as the last time of use.

[0073] Specifically, Fig. 9 shows a flow in which the smartphone 101 of this embodiment executes the operations of sending periodic notifications and abnormality notifications to the management center device 10. The flow in Fig. 9 is the same as the flow in the first embodiment except that step S8-1 in which the distance measuring unit 27 detects whether or not there has been a change in the distance to the paired wireless earphone 3, which is a child device, and step S8-2 in which, if the change in distance can be detected (step S8-1: Y), the time of the distance change is linked to location information and updated and saved as the last use time, are provided between step S8 in Fig. 3 in which the operation time on the smartphone is updated and saved, and step S9 in which the motion time or the last use time at the time of operation is detected within a certain period.

[0074] (Explanation of effect) According to the second embodiment, by using a wearable communication terminal that is always worn by a user who is capable of pairing, it is possible to detect the movement of the user (the person carrying the smartphone 101) while the smartphone 101 itself is left in place.

[0075] Examples of wearable communication terminals that can be paired with the smartphone 101 and that are always worn by the user include wireless earphones 3 and portable computer communication terminals such as smart watches (smart wristwatches) that are equipped with notification means.

[0076] [Note] In addition, the following supplementary notes are provided in connection with the above description of the embodiment.
