Description

  The present invention relates to a forgotten object notification system, a portable communication device, and a user side communication terminal.

If a mobile communication device such as a mobile phone is left behind somewhere, it is very difficult to specify the location of the mobile communication device. With respect to such a problem, Patent Document 1 discloses that even if a wireless station is installed in a place called a hot spot such as a restaurant, pub, hotel, inn, amusement park, etc., even if the mobile phone is left behind in those places. , There is a description that the user can specify the place left behind.
JP 2003-348659 A

  However, in the description of Patent Document 1, although it can be understood that a radio station and a mobile phone communicate, it does not describe how the position of the mobile phone can be specified.

  In view of the above points, the present invention provides a technique capable of specifying the position of a misplaced portable communication device using a wireless station when a wireless station capable of communicating with the portable communication device is installed. For the purpose.

  In order to achieve the above object, an invention described in claim 1 relates to a lost article notification system including a plurality of infrastructure side communication devices (2a, 2b, 2c) and servers (3, 5). Here, each of the plurality of infrastructure side communication devices is capable of wireless communication with the mobile communication device (1), and the respective communicable areas are different.

  In such a forgotten object notification system, each of the plurality of infrastructure side communication devices receives information indicating that the mobile communication device is not under the control of the user and the mobile communication from the mobile communication device in the communicable area of the own device. Based on the fact that the forgotten thing state data including the information for specifying the machine is received, the location information of the own machine is included in the received forgotten thing state data and transmitted to the server.

  Further, the server receives the first forgotten thing state data transmitted from the first infrastructure side communication device (2a) among the plurality of infrastructure side communication devices, based on the reception of the first forgotten thing state data. The location information of the included first infrastructure side communication device is notified as the location of the mobile communication device specified in the first forgotten thing state data.

  As described above, the location of the first infrastructure communication device communicating with the mobile communication device among the plurality of infrastructure communication devices having different communicable areas is regarded as the location of the mobile communication device. Thus, the location of the portable communication device can be specified with accuracy about the size of the communicable area of the first infrastructure-side communication device.

  Note that “notification” here is a concept that includes both notifications that limit the notification partner (for example, transmission limited to an e-mail address) and notifications that do not limit the notification partner (for example, notification as a WEB service). . Further, the transmission of the forgotten thing state data from the first infrastructure side communication device to the server may be direct or may be indirect via another communication device.

  Further, the location information of the infrastructure side communication device may be any information as long as the location location information of the infrastructure side communication device is known. For example, it may be a communicable area of the infrastructure side communication device. For example, when the location of the infrastructure communication device is fixed and the correspondence between the infrastructure communication device and the location is known, information for identifying the infrastructure communication device (for example, an identification code, Mobile phone number) can also be location information.

  According to a second aspect of the present invention, the server may include a storage medium (52) that stores a plurality of sets of correspondence data between the wireless communication device and the notification destination communication device. In this case, when the server receives the first forgotten thing state data transmitted from the first infrastructure side communication device, the server applies the portable communication device specified in the first forgotten thing state data to the corresponding relationship data. Thus, the notification destination communication device (8, 10) corresponding to the first forgotten thing state data may be specified. Further, the server may transmit the location information of the portable communication device included in the first forgotten state data to the specified notification destination communication device.

  As described above, by storing the correspondence relationship data between the wireless communication device and the notification destination communication device in advance in the server, the destination for notifying the location information of the portable communication device is determined based on the correspondence relationship data. be able to. As a result, it is possible to easily specify an appropriate notification destination communication device (for example, a notification destination communication device as a contact address for the user of the portable communication device) at the location of the misplaced mobile communication device.

  According to a third aspect of the present invention, the server stores the forgotten item state data for identifying the portable communication device based on the reception of the remote setting signal for controlling the function restriction of the portable communication device from the notification destination communication device. The remote setting signal may be transmitted to the first infrastructure-side communication device that is the transmission source. In that case, the first infrastructure side communication device may transmit the remote setting signal to the portable communication device based on the reception of the remote setting signal.

  In this way, the infrastructure side communication device not only notifies the location information of the mobile communication device that has been left behind via the server to the appropriate notification destination communication device, but also from the notification destination communication device to the server, It becomes possible to remotely control the function restriction of the portable communication device via the infrastructure side communication device.

  According to a fourth aspect of the present invention, after the server receives the first forgotten thing state data from the first infrastructure side communication device, the server is the first infrastructure side communication device among the plurality of infrastructure side communication devices. When the second forgotten thing state data transmitted from a different second infrastructure side communication device (2b) is received, the portable communication device specified in the second forgotten thing state data and the first forgotten thing state data Based on the fact that the specified portable communication device is the same, the location of the portable communication device specified in the first and second lost article state data is included in the second lost article state data. The location information of the second infrastructure side communication device may be updated to notify the updated location location.

  If a portable communication device is stolen, etc. and is carried by someone (or something) and moves, if the communicable area to which the portable communication device belongs changes according to the movement, the communication on the infrastructure side that is different from before The forgotten thing state data for specifying the same portable communication device is transmitted from the device. According to the above configuration, if the server receives the forgotten thing state data of the same portable communication device from a different infrastructure side communication device, the server newly sets the location specified in the newly received forgotten state data. Replace with the location specified in the forgotten item status data of the recipient. Therefore, the server can perform the location notification following the movement of the mobile communication device.

  In addition, as described in claim 5, the portable communication device capable of communicating with the forgotten object notification system as described above detects that the own device has not been operated by the user for a reference time or longer, and based on the detection. Among the plurality of infrastructure side communication devices (2a, 2b, 2c), the forgotten item state data (that is, the own device is not under the control of the user) with respect to the infrastructure side communication device within the communicable area. And data including information identifying the own device) may be transmitted.

  As described above, when the portable communication device transmits the forgotten item state data when it is left for a reference time or longer, it is possible to detect misplacement with high accuracy.

  In addition, as described in claim 6, the portable communication device changes the function restriction content of the own device based on the reception of the remote setting signal from the first infrastructure communication device of the lost-item notification system. It may be. In this way, detailed function restriction by remote operation of the portable communication device is realized.

  In addition, as described in claim 7, the portable communication device prohibits the transmission of the forgotten item state data when the portable device is in a user's own management area set in advance. Also good.

  In this way, even if the portable communication device is left for more than the reference time, an area (for example, at home, in the own vehicle, etc.) where the portable communication device is not necessarily left behind. If the management area is determined in advance, it is possible to suppress transmission of unnecessary forgotten state data.

  Alternatively, as described in claim 8, the portable communication device uses the first time as the reference time when there is no device in the management area, and when the device is in the management area, A second time longer than one time may be used as the reference time.

  As described above, the portable communication device may transmit the forgotten item state data even if the portable device is in the management area. Therefore, for example, in response to a case where the portable communication device leaves the user's management due to vehicle theft or the like, it is possible to transmit forgotten thing state data and to identify the position of the portable communication device.

  However, since the possibility of theft in the management area is lower than the possibility of misplacement outside the management area, the time used as the reference time in the user management area is longer in the former. As a result, in the management area, it is possible to suppress transmission of unnecessary forgotten thing state data to some extent while sending forgotten thing state data.

  In addition, as described in claim 9, a user-side communication terminal that can communicate with the forgotten object notification system according to any one of claims 1 to 5 receives location information of the portable communication device from the server. May be recorded. In this case, the user side communication terminal may detect the approach of the user to the own device, and display the recorded location information to the user based on the detection.

  In this way, when the user is not near the user side communication terminal, even when the location information of the portable communication device is received from the server and recorded, the user approaches the user side communication terminal. Moreover, since the location information is automatically notified to the user, when the user is not aware of the misplacement of the portable communication device, not only the misplaced position but also the misplacement itself can be quickly noticed.

  In addition, as described in claim 10, the user side communication terminal may display a route to the recorded location. This makes it easy for the user to go to collect the portable communication device.

  In addition, the code | symbol in the bracket | parenthesis in the said and the claim shows the correspondence of the term described in the claim, and the concrete thing etc. which illustrate the said term described in embodiment mentioned later. .

  The vehicle navigation device 8 includes an out-of-vehicle communication unit 81, an in-vehicle communication unit 82, a display unit 83, an operation unit 84, a storage unit 85, and a control unit 86. A user detection device 41 and a power supply controller 42 are mounted in the vehicle 7.

  The user detection device 41 is a sensor that detects the user's entry into the vehicle and outputs a signal to that effect to the power supply controller 42 and the control unit 86 of the vehicle navigation device 8 at the time of detection. Examples of the user detection device 41 include a sensor that detects that the user has touched the door knob on the outside of the vehicle, a sensor that detects that the door is opened, and a sensor that detects the approach of the user to the vehicle around the vehicle. .

  The power supply controller 42 is a device that controls supply / non-supply of power to the vehicle navigation device 8. Specifically, upon receiving a signal indicating that the user has been detected from the user detection device 41, the power supply controller 42 turns on the power supply to the vehicle navigation device 8, thereby starting the vehicle navigation device 8. To do.

  When the power supply controller 42 receives a reception start notification signal, which will be described later, from the vehicle exterior communication unit 81, the power supply controller 42 turns on the power supply to the vehicle navigation device 8, thereby starting the vehicle navigation device 8. When the power supply controller 42 receives a reception end notification signal, which will be described later, from the vehicle exterior communication unit 81, the power supply controller 42 turns off the power supply to the vehicle navigation device 8, thereby the vehicle navigation device 8 (however, the vehicle exterior communication unit 81). ) Is stopped.

  The outside communication unit 81 is wirelessly connected to a base station (for example, the wireless base station 6a) in the vicinity of the inside 7 of the vehicle, and communicates with a communication device (for example, the forgotten item server 5) on the wide area communication network 4 through the wireless connection.

  Next, an operation example of the lost article notification system in the present embodiment will be described. FIG. 8 is a sequence diagram showing the operation of the lost article notification system. The example of this figure has shown the action | operation in the scene where the user of the portable communication apparatus 1 left the portable communication apparatus 1 in the communication area of the facility communication apparatus 2a.

  The control unit 24 of the infrastructure side communication device 2 such as the facility communication devices 2a and 2b periodically transmits a call signal (polling) using the narrow area communication units 22a to 22c (step 102). When the control unit 17 of the mobile communication device 1 receives this call signal via the narrow area communication unit 12, the control signal is sent to the transmission side infrastructure side communication device (facility communication in the example of FIG. 8). Return to machine 2a).

  Also, the portable communication device 1 enters the forgotten item mode (step 110) based on the fact that the user's operation on the portable communication device 1 is not longer than the reference time (step 108). In order to realize this operation of the portable communication device 1, the control unit 17 executes a program 200 shown in FIG.

  In executing the program 200, the control unit 17 first determines in step 220 whether or not the position of the own device is outside the user management area. The user management area refers to an area under user management. Therefore, even if the portable communication device 1 is left in this user management area for a reference time or more, the portable communication device is often not left behind. The user management area includes, for example, in-vehicle 7 and in-home 9 in FIG.

  Whether or not the own device is outside the user management area is determined based on, for example, a transmitter identification code included in a signal received by the control unit 17 via the narrow area communication unit 12. Also good.

In particular,
(1) A signal is received via the narrow area communication unit 12.
(2) The received signal includes an identification code of the device that is the transmission source of the signal,
(3) The identification code matches one of one or a plurality of managed device identification codes recorded in the storage unit 16 of the mobile communication device 1 in advance.
When all the three conditions are satisfied, it is determined that the own device is not outside the user management area (that is, the own device is within the user management area), and even one of these three conditions is not satisfied. Sometimes, it is determined that the own device is outside the user management area.

  Examples of the managed device identification code recorded in the storage unit 16 include an identification code of the vehicle navigation device 8 mounted on the user's vehicle and an identification code of the wireless LAN router installed in the user's home 9. Etc. In this case, the inside 7 of the vehicle and the inside 9 of the home are user management areas, and other places are outside the user management area.

  If the determination result of step 220 is affirmative, then step 230 is executed, and if negative, the determination of step 220 is executed again. In Step 230, it is determined whether or not the condition that “the user's operation on the operation unit 14 has not been performed for a first reference time (for example, 2 minutes) or longer” is satisfied. If not satisfied, step 220 is executed again.

  In step 240, a level 1 lock is performed. Here, “lock” refers to a restriction on the function of the mobile communication device 1. The function restriction refers to invalidating part or all of a plurality of types of functions (for example, a telephone call function, an e-mail reception browsing function, and an e-mail transmission function) that can be executed by the mobile communication device 1. .

  There are several levels of locks. As the level increases, the degree of function restriction increases, that is, the number of functions to be disabled increases. For example, the level 1 lock disables only the e-mail transmission function, the higher level 2 lock disables the telephone call function in addition to the e-mail transmission function, and the higher level 3 lock disables the e-mail transmission function. In addition to the telephone call function, the e-mail receiving function is disabled. Note that the level of the lock applied in step 240 may be other than level 1.

  Subsequently, in step 250, in order to reduce power consumption, the state transits to the sleep state (if it is not currently in the sleep state). Further, a time during which the sleep state continues (that is, an elapsed time since the last transition to the sleep state: hereinafter referred to as sleep integrated time) is measured.

  Subsequently, in step 260, it is determined whether or not the release condition is satisfied. If not satisfied, step 280 is subsequently executed, and if satisfied, step 270 is subsequently executed. As a case where the release condition is satisfied, there is a case where a predetermined unlock operation has been performed on the operation unit 14. As the unlocking operation, for example, there is a predetermined password input operation.

  In step 270, the mobile communication device 1 is unlocked in response to the release condition being satisfied, and then step 220 is executed again.

  In step 280, it is determined whether or not the sleep integration time has exceeded a second reference time (longer than the first reference time: for example, 10 minutes). If not, step 250 is executed again. In step 290, the forgotten item mode is entered. When entering the forgotten item mode, the control unit 17 causes the display unit 13 to display a notification screen as shown in FIG.

  In this way, when the mobile communication device 1 is outside the user management area (see step 220), the level of the mobile communication device 1 is determined based on the fact that there is no user operation on the own device for the first reference time (see step 230). 1 is executed (see step 240) and the sleep state is further entered (see step 250), and the duration of the sleep state exceeds the second reference time (see step 280) or the release condition is satisfied (see FIG. Wait until step 260). When the duration of the sleep state exceeds the second reference time, the forgotten item mode is entered. Alternatively, if the release condition is satisfied before the duration of the sleep state exceeds the second reference time, the mobile communication device 1 is unlocked (see step 270).

  When the mobile communication device 1 receives a user operation in an unlocked state, the mobile communication device 1 separately performs various processes (for example, telephone call processing, e-mail transmission processing, text editing processing) according to the operation. It has become.

  After entering the forgotten item mode, the portable communication device 1 transmits the forgotten item state data to the facility communication device 2a when a call signal is transmitted from the facility communication device 2a (see step 112 in FIG. 8) (see FIG. 8). Step 114).

  For the transmission of the lost article state data, the control unit 17 executes the program 300 shown in FIG. 11 immediately after entering the lost article mode. First, in step 310, a lock of a level higher than the previous lock level (for example, level 2 lock) is executed.

  Subsequently, at step 320, the forgotten thing state data is transmitted to the nearby infrastructure side communication device using the narrow area communication unit 12. The forgotten item status data includes (1) predetermined information indicating that the mobile communication device 1 is not under the control of the user (hereinafter referred to as a forgotten item flag), and (2) an identification code that can uniquely identify the mobile communication device 1. (Hereinafter referred to as mobile ID).

  Subsequently, in step 330, it is determined whether the receipt confirmation (ACK) of the forgotten item state data is received from a nearby infrastructure communication device. If not received, the lost item state data is transmitted again in step 330. If yes, then step 350 is executed.

  In step 350, it is determined whether or not a call signal has been received from a nearby infrastructure side communication device. If it has been received, then in step 375, lost property state data is transmitted, and then step 350 is executed again.

  As described above, when the portable communication device 1 enters the forgotten item mode, the mobile communication device 1 sets the lock level higher than before (see step 310), and sets the forgotten item state data in the vicinity (that is, the own device belongs to the communication area). The transmission is voluntarily transmitted to the infrastructure side communication device (facility communication device 2a in the example of FIG. 8), and the transmission is repeated until it is confirmed that the transmission has surely reached the infrastructure side communication device (see step 330).

  Thereafter, each time the mobile communication device 1 receives a call signal from a nearby infrastructure-side communication device (see step 350), the portable communication device 1 sends back forgotten thing state data correspondingly (see step 375).

  When the mobile communication device 1 receives a signal other than a call signal and a remote setting signal described later, the mobile communication device 1 separately performs various processes (for example, incoming call processing and e-mail reception processing) according to the contents of the signal. It has become.

  When the forgotten thing state data is transmitted from the portable communication device 1, the control unit 24 of the infrastructure side communication device (facility communication device 2a in the example of FIG. 8) in the vicinity of the portable communication device 1 controls the narrow area communication units 22a to 22c. The forgotten thing state data is received via one of them, and the received forgotten thing state data is added to the identification code (hereinafter referred to as infrastructure ID: an example of the location information) of the own device (in the example of FIG. 8, the facility communication device 2a). The forgotten thing state data as a result is transmitted to the facility management server 3 via the network interface unit 21 (step 118). The infrastructure ID may be a map code of the location of the infrastructure side communication device or a range of position coordinates (latitude, longitude, altitude).

  Thereafter, the control unit 24 associates the portable ID in the received forgotten item state data with the forgotten item flag and records them in the storage unit 23 (step 116). In this way, the infrastructure side communication device can store information for specifying the portable communication device that is in the forgotten item mode within the communication area of the own device.

  When the forgotten item state data is transmitted from the facility communication device 2a to the facility management server 3, the control unit 34 of the facility management server 3 receives the forgotten item state data via the dedicated network interface unit 32, and further, the wide area network interface The received forgotten item state data is transmitted to the forgotten item server 5 via the unit 31 (step 119).

  Further, the control unit 34 refers to the infrastructure ID in the received forgotten item state data and the correspondence table recorded in advance in the storage unit 33, and identifies the presence area of the infrastructure side communication device that is the source of the forgotten item state data. Further, the presence area is specified as the presence area of the portable communication device 1 (step 120).

  The correspondence table includes an infrastructure ID and information on the location of the infrastructure side communication device corresponding to the infrastructure ID (for example, latitude / longitude / height, a specific section in the facility, a specific store name, a specific store name, etc. This data includes a plurality of sets of correspondence relationships with parking lot names and the like.

  Further, the control unit 34 creates information associating the identified area of the portable communication device 1 with the portable ID in the forgotten thing state data as WEB data (for example, HTML data), and creates the WEB data. For example, it functions as a WEB server so that other communication devices can be accessed (via the wide area communication network 4) (step 122).

  When the lost property state data is transmitted from the facility management server 3 to the lost property server 5, the control unit 53 of the lost property server 5 receives the lost property state data via the network interface unit 51, and the infrastructure in the received lost property state data. With reference to the ID and the first correspondence table recorded in advance in the storage unit 52, the presence area of the infrastructure side communication device that is the transmission source of the forgotten object state data is specified, and the existence area is further defined in the portable communication device 1 It is specified as an existing area (step 123). The contents of the first correspondence table are the same as the correspondence table in the facility management server 3. Note that the control unit 53 may receive information on the area where the mobile communication device 1 exists from the facility management server 3. If the infrastructure ID is a map code or a position coordinate range, it may be specified as an existing area.

  Further, the control unit 53 refers to the second correspondence table recorded in advance in the storage unit 52, and specifies the notification destination address (e-mail address, IP address, etc.) corresponding to the mobile ID in the received forgotten item state data. Then, the forgotten thing state data is transmitted to the specified notification destination via the network interface unit 51 (step 124). Note that a plurality of sets of mobile IDs and notification destination addresses corresponding to the mobile IDs are recorded in the second correspondence table.

  In addition, when forgotten thing state data is transmitted from the facility management server 3 to a notification destination communication device such as the vehicle navigation device 8 or the personal computer 10 as a notification destination corresponding to the portable ID in the forgotten thing state data, the notification destination communication The device records the received forgotten item state data (step 125).

  For example, when the control unit 95 of the operating personal computer 10 receives the forgotten item state data via the network interface unit 91, the control unit 95 records the forgotten item state data in the storage unit 94.

  Further, for example, when the vehicle exterior communication unit 81 of the vehicle navigation device 8 receives the forgotten thing state data, the vehicle exterior communication unit 81 outputs a reception start notification to the power supply controller 42, and the power supply controller 42 correspondingly responds to the vehicle The power supply to the navigation device 8 is turned on, and the control unit 86 activated thereby acquires the forgotten thing state data from the outside communication unit 81 and records the acquired forgotten thing state data in the storage unit 85. After the recording, the outside communication unit 81 (or the control unit 86) outputs a reception end notification to the power controller 42, and the power controller 42 turns off the power supply to the vehicle navigation device 8 accordingly. To do.

  Thereafter, when the notification destination communication device detects that the user has approached the vicinity of the own device, the notification destination communication device notifies the user of the information of the recorded forgotten object state data (step 126).

  For example, when the user approaches the personal computer 10, the user detection device 90 of the personal computer 10 detects the presence of the user and outputs a signal to that effect to the control unit 95. Then, based on the signal, the control unit 95 displays the information on the presence area of the portable communication device 1 received and recorded in the storage unit 94 to the user using the display unit 93.

  Further, for example, when the user approaches the vicinity of the vehicle navigation device 8 (that is, inside the vehicle 7), the user detection device 41 detects this and outputs a signal to that effect (hereinafter referred to as an approach signal) to the power supply controller 42. The power supply controller 42 turns on the power supply to the vehicle navigation device 8 based on the receipt of the approach signal. When the control unit 86 is activated, the user detection device 41 also outputs an approach signal to the control unit 86.

  After starting, the control unit 86 executes the program 400 shown in FIG. 12. First, in step 410, it is determined whether or not the user has approached based on the presence or absence of an approach signal from the user detection device 41. If it is determined, step 430 is subsequently executed. If it is not determined that the vehicle is approaching, step 410 is executed again.

  In step 430, the forgotten thing state data recorded in the storage unit 85 is read out, and based on the read out forgotten thing state data, an image or a character indicating the information on the existing area of the portable communication device 1 is generated, and the generated image or character is generated. Is displayed on the display unit 83. As a result, the vehicle navigation device 8 can automatically notify the user of the location of the portable communication device 1 (that is, without requiring the user's special operation).

  Examples of images to be displayed on the display unit 83 include images as shown in FIGS. The images in FIGS. 13 and 14 are images for performing display while changing the degree of detail step by step when an infrastructure-side communication device is installed for each table in a store in a shopping street.

  The image shown in FIG. 13 includes a map 71 of a shopping street, a mark 73 indicating a store 72 including an existing area on the map, a route 74 to the store 72, and a detailed view in the store 72. , A route guidance button 76, and a remote control button 77. The buttons 75, 76, and 77 can be selected by the user using the operation unit 84. Moreover, the name and telephone number of the store 72 may be displayed on the image shown in FIG.

  When the user selects the button 75, the control unit 86 causes the display unit 83 to display the image shown in FIG. The image shown in FIG. 14 indicates the map 71 in the store 72, the mark 42 that indicates the presence area on the map, and the reception area in the store 72 (that is, the area where the reception staff is present). And a remote control button 44.

  The vehicle navigation device 8 displays such an image, so that the user can visually grasp the location of the mobile communication device 1.

  The control unit 86 stores a map as shown in FIGS. 13 and 14 and information about the arrangement of the store 73, the presence area 42, and the reception area 43 (hereinafter referred to as arrangement information) in the map. It may be read from the map data inside, may be received from the forgotten item server 5 together with the forgotten item state data, and is received from the facility management server 3 via the forgotten item server 5. It may be.

  Further, the control unit 86 may be configured to calculate a route 74 as shown in FIG. 13 based on the map data in the storage unit 85, or to receive the lost item status data from the lost item server 5. It may be received, or may be received from the facility management server 3 via the forgotten item server 5. When the control unit 86 receives the route 74, the forgotten item server 5 or the facility management server 3 that is the transmission source of the route 74 calculates the route 74.

  Further, in step 440 following step 430, the control unit 86 determines whether or not the user has confirmed the forgotten item information displayed on the display unit 83 based on whether or not a predetermined operation has been performed on the operation unit 84. If it is determined, step 450 is executed, and if it is determined that confirmation has not been made, step 430 is executed.

  Subsequently, in step 450, whether or not the user intends to immediately collect the portable communication device 1 is determined based on a user operation on the operation unit 84. In the display examples shown in FIGS. 13 and 14, if the route guidance button 76 of FIG. 13 is selected within a predetermined time, the determination result of step 450 becomes affirmative, and then step 460 is executed. If not, the determination result in step 450 is negative, and then the execution of the program 400 ends.

  In step 460, route guidance according to the route 74 is realized by the navigation processing described above. After step 460, execution of program 400 ends.

  In addition, the portable communication device 1 may not only be misplaced but also move. As a cause of the movement, the person who picked up the portable communication device 1 (or the thief) has to move. In such a case, when the portable communication device 1 enters the communication area of the facility communication device 2b from the communication area of the facility communication device 2a, the control unit 17 is transmitted from the facility communication device 2b in step 350 of FIG. (Step 127 in FIG. 8) The call signal is received, and the forgotten thing state data is transmitted in Step 375 accordingly (Step 128).

  Then, similarly to the facility communication device 2a, the control unit 24 of the facility communication device 2b includes the infrastructure ID of the own device (corresponding to an example of the location information) in the received forgotten property state data, and the forgotten property state data as a result thereof. Is transmitted to the facility management server 3 via the network interface unit 21 (step 130). In addition, the control unit 24 of the facility communication device 2b associates the portable ID in the received forgotten thing state data with the forgotten thing flag and records it in the storage unit 23 (step 132).

  When the forgotten item state data is transmitted from the facility communication device 2b to the facility management server 3, the facility management server 3 transmits the received forgotten item state data to the forgotten item server 5 in the same process as in step 119 (step 138).

  Further, as in step 120, the facility management server 3 refers to the infrastructure ID in the received forgotten thing state data and the correspondence table recorded in advance in the storage unit 33, and the infrastructure side that is the transmission source of the forgotten thing state data. Identify the communication area.

And if the existence area about the same portable ID as the portable ID in the received forgotten thing state data is currently recorded in the storage unit 33, the newly received existence area is set as a new existence area of the portable communication device 1. Replace with the existing area that was previously recorded. That is, the presence area of the portable communication device 1 is updated (step 134). Further, the facility management server 3 updates the WEB data created in step 122 using the newly specified existence area (step 136).
When the forgotten item state data is transmitted from the facility management server 3 to the forgotten item server 5, the forgotten item server 5 specifies the existence area of the infrastructure side communication device that is the transmission source of the forgotten item state data, as in step 123. And if the existence area about the same portable ID as the portable ID in the received forgotten thing state data is recorded in the storage unit 52, the newly received existence area is set as a new existence area of the portable communication device 1. Replace with the existing area that was previously recorded. That is, the presence area of the mobile communication device 1 is updated (step 140).

  Similarly to step 124, the forgotten item server 5 specifies the address of the notification destination corresponding to the mobile ID in the received forgotten item state data, and transmits the forgotten item state data to the specified notification destination (step 142).

  In addition, when the forgotten item state data is transmitted from the forgotten item server 5 to the notification destination communication device such as the vehicle navigation device 8 or the personal computer 10 as the notification destination corresponding to the portable ID in the forgotten item state data, the notification destination communication device Records the received forgotten thing state data (step 144).

  Note that the notification destination communication device may be configured to notify the user of the position of the mobile communication device 1 by executing step 430 and subsequent steps in FIG. 12 based on the received forgotten thing state data.

  Thereafter, the user can perform remote control such as the lock level of the portable communication device 1 by operating the notification destination communication device. For example, in the personal computer 10, when the user performs an operation for requesting remote control of the portable communication device 1 on the operation unit 92 (step 146), the control unit 95 sends a remote setting signal to the forgotten item state. The infrastructure side communication device and the portable communication device 1 that are the data transmission sources are transmitted to the forgotten item server 5 as final destinations (step 148). The said infrastructure side communication apparatus and the portable communication apparatus 1 identify using the infrastructure ID and portable ID in the last thing received forgotten thing state data.

  Further, for example, in the vehicle navigation device 8, the control unit 86 performs the operation for requesting remote control of the portable communication device 1 on the operation unit 84 when the program 400 is executed (for example, the user If the remote control buttons 77 and 44 in FIGS. 13 and 14 are selected, step 146 in FIG. 8), the remote setting signal is sent to the final destination of the infrastructure side communication device and portable communication device 1 that are the source of the forgotten item state data. Then, it is transmitted to the forgotten item server 5 (step 148 in FIG. 8).

  Information included in the remote setting signal is information specifying the lock level of the portable communication device 1, information indicating whether or not the forgotten item mode is released, and the like. The lock level to be designated and whether or not to leave the forgotten item mode are determined based on the user's operation details on the operation unit 84.

The forgotten item server 5 transfers the remote setting signal received from the vehicle navigation device 8 to the facility management server 3 connected to the destination infrastructure side communication device (facility communication device 2b in the example of FIG. 8) (step 152). . Further, when the facility management server 3 receives the transferred remote setting signal, the facility management server 3 transmits it to the destination infrastructure side communication device (step 154). Further, when receiving the remote setting signal, the infrastructure side communication device transmits it to the destination portable communication device 1 (step 156).
When receiving the remote setting signal, the control unit 17 of the portable communication device 1 receives the remote setting signal in step 360 following the case where the call signal is not received from the nearby infrastructure side communication device in step 350 of FIG. Then, step 380 is executed. If it is determined that the data has not been received, step 350 is executed again.

  In step 380, the lock level of the portable communication device 1 is set based on the content of the remote setting signal received in the immediately preceding step 360. Subsequently, in Step 385, it is determined whether or not the remote setting signal received in the immediately preceding Step 360 includes information indicating that the forgotten item mode is released. If not included, Step 350 is executed again. If it is, then the lost article mode is canceled in step 390, and then the execution of the program 300 is terminated.

  As described above, when the mobile communication device 1 receives a remote setting signal from a nearby infrastructure communication device (see step 360), the mobile communication device 1 sets a lock level according to the content of the remote setting signal (step 380). If the signal contains a lost article mode release command (see step 385), the lost article mode is released (see step 390). This process corresponds to the process in step 158 of FIG.

  The control unit 17 performs processing according to the content of the remote setting signal, and then transmits a processing completion notification to the nearby infrastructure side communication device (facility communication device 2b in the example of FIG. 8) (step 160). The infrastructure side communication device that has received this processing completion notification transfers the processing completion notification to the facility management server 3 (step 162), and the facility management server 3 that has received the processing completion notification sends the processing completion notification to the forgotten item server. 5 (step 164).

  In addition, the forgotten item server 5 that has received this processing completion notification transfers the processing completion notification to the notification destination communication device (from which the remote setting signal is transmitted) (step 168), and records the completion of the remote control processing. (Step 166). Further, the notification destination communication device that has received this processing completion notification records the completion of the remote control processing (step 170).

  By the operation of the lost article notification system as described above, notification to the user of the area where the mobile communication device 1 exists and remote control of the function restriction of the mobile communication device 1 by the user are realized.

  That is, in the lost article notification system, each of the plurality of infrastructure side communication devices 2a to 2c is based on the fact that the portable communication device 1 has received the lost item status data from the portable communication device 1 within the communicable area of the own device. Then, the location information of the own machine is included in the received forgotten thing state data and transmitted to the forgotten item server 5 via the facility management server 3 and the facility management server 3.

  In addition, the facility management server 3 receives the forgotten item state data transmitted from one of the plurality of infrastructure side communication devices (for example, the facility communication device 2a), and then the infrastructure side included in the forgotten item state data. The location information of the communication device is notified in the form of WEB data as the location of the mobile communication device 1 specified in the forgotten item state data.

  Also, the forgotten thing server 5 receives the location information of the infrastructure side communication device included in the forgotten thing state data based on receiving the forgotten thing state data transmitted from one of the plurality of infrastructure side communication devices. As a location of the portable communication device 1 specified in the forgotten item state data, a notification destination communication device registered in advance corresponding to the portable communication device is notified.

  Thus, among the plurality of infrastructure side communication devices 2a to 2c having different communicable areas, the location of the infrastructure side communication device communicating with the mobile communication device is regarded as the location of the mobile communication device. Thus, the location of the portable communication device 1 can be specified with accuracy about the size of the communicable area of the infrastructure side communication device.

  In addition, the portable communication device 1 capable of communicating with the forgotten object notification system as described above detects that its own device has not been operated by the user for a reference time or longer, and based on the detection, a plurality of infrastructure side communication devices. Among them, the forgotten thing state data is transmitted to the infrastructure side communication device in the communicable area.

  As described above, when the portable communication device 1 transmits the forgotten thing state data when it is left unattended for the reference time or more, it is possible to detect misplacement with high accuracy.

  In addition, the portable communication device 1 prohibits transmission of forgotten item state data when the own device is in the user's own management area set in advance.

  In this way, even if the portable communication device 1 is left unattended for a reference time or longer, the area where the portable communication device 1 is not necessarily left behind (for example, at home, in its own vehicle, etc.) ) As a management area in advance, it is possible to suppress transmission of unnecessary forgotten item state data.

  In addition, the portable communication device 1 is configured to change the function restriction content of the own device based on the reception of the remote setting signal from the first portable communication device of the left behind notification system. In this way, detailed function restriction by remote operation of the portable communication device is realized.

  Also, the forgotten item server 5 stores a second correspondence table (corresponding to a plurality of sets of correspondence data) between the wireless communication device and the notification destination communication device, and the forgotten item state transmitted from the infrastructure side communication device When the data is received, by applying the portable communication device 1 specified in the forgotten item state data to the second correspondence table, the notification destination communication device corresponding to the forgotten item state data is specified and specified The location information of the portable communication device included in the forgotten item state data is transmitted to the previous communication device.

  As described above, by storing the second correspondence table in the forgotten item server 5 in advance, it is possible to determine the destination of the location information of the portable communication device 1 based on the second correspondence table. Thereby, it is possible to easily specify an appropriate notification destination communication device (for example, a notification destination communication device as a contact to the user of the portable communication device 1) at the location of the misplaced mobile communication device 1.

  In addition, the facility management server 3 and the forgotten item server 5 receive the forgotten item state data for specifying the above-described portable communication device 1 based on receiving the remote setting signal for controlling the function restriction of the portable communication device 1 from the notification destination communication device. The remote setting signal is transmitted to the infrastructure-side communication device that is the transmission source. In that case, the infrastructure side communication device transmits the remote setting signal to the portable communication device 1 based on the reception of the remote setting signal.

  In this way, the infrastructure side communication device not only notifies the location information of the mobile communication device 1 left behind via the forgotten item server 5 and the facility management server 3 to an appropriate notification destination communication device. The function restriction of the portable communication device 1 can be remotely controlled from the notification destination communication device via the forgotten item server 5, the facility management server 3, and the infrastructure side communication device.

  In addition, the portable communication device 1 changes the restriction content of the function of the own device based on the reception of the remote setting signal from the infrastructure side communication device of the left behind notification system. In this way, detailed function restriction by remote operation of the portable communication device is realized.

  In addition, the facility management server 3 and the forgotten item server 5 have received the first forgotten item state data (see steps 118 and 119 in FIG. 8) from the facility communication device 2a (corresponding to an example of the first infrastructure side communication device). Thereafter, when second forgotten thing state data (refer to steps 130 and 138) transmitted from the facility communication device 2b (corresponding to an example of the second infrastructure side communication device) is received, Based on the fact that the specified portable communication device 1 and the portable communication device 1 specified in the first forgotten thing state data are the same, the relevant specified in the first and second forgotten state data The location of the portable communication device 1 is updated to the location information of the infrastructure-side communication device included in the second forgotten thing state data, and the updated location is notified.

  If the portable communication device 1 has been picked up, stolen, etc., carried by someone (or something) and moved, if the communicable area to which the portable communication device belongs changes according to the movement, it will be different from before Forgotten thing state data for identifying the same portable communication device is transmitted from the infrastructure side communication device. According to the configuration as described above, the facility management server 3 and the forgotten item server 5 are specified in the forgotten item state data of the newly received one if the forgotten item state data of the same portable communication device is received from a different infrastructure side communication device. The existing location is replaced with the location specified in the forgotten object state data of the newly received person. Therefore, the facility management server 3 and the forgotten item server 5 can perform a location notification following the movement of the portable communication device.

  In addition, the notification destination communication device (corresponding to the user side communication terminal) receives and records the location information of the portable communication device 1 from the forgotten item server 5, and further detects the approach of the user to the own device, Based on the detection, the recorded location information is displayed to the user.

  In this way, when the user is not in the vicinity of the notification destination communication device (for example, the vehicle navigation device 8 or the personal computer 10), the location information of the portable communication device 1 is received from the forgotten item server 5. Even when the user approaches the notification destination communication device, the location information is automatically notified to the user, so when the user has not noticed that the portable communication device 1 has been misplaced, the misplaced position Not only that, you can notice the misplacement itself.

  The vehicle navigation device 8 displays and guides the route to the recorded location. With this configuration, it is easy for the user to go to collect the portable communication device 1.

  The mobile communication device 1 has a lock level divided into a plurality of stages as described above (for example, locks of levels 1 to 3), and locks other than the lowest level (that is, the level with the weakest restriction) among them. Is executed, the control unit 17 may gradually lower the lock level in accordance with a user operation on the operation unit 14 and finally release the lock.

  For example, as shown in FIG. 15, when the level 3 lock is applied, the control unit 17 notifies the display unit 13 of the lock level and inputs predetermined data 1 (specifically, a user name). When the prompt image 61 is displayed and the data is input to the operation unit 14, the lock level is lowered by one step and the level 2 lock is executed.

  In addition, after executing the level 2 lock, the control unit 17 notifies the display unit 13 that the data 1 has been input, and the predetermined data 2 (specifically, among the lock passwords set in advance by the user) When any of the images 62 prompting the input is displayed and the data is input to the operation unit 14, the lock level is lowered by one step and the level 1 lock is executed.

  Then, after executing the level 1 lock, the control unit 17 notifies the display unit 13 that the data 2 has been input, and the predetermined data 3 (specifically, among the lock passwords set by the user in advance). When any of the images 63 prompting input is displayed and the data is input to the operation unit 14, the lock is released. Thereafter, the control unit 17 causes the display unit 13 to display an image 64 indicating that the data 3 has been input and that the lock is to be released.

  Note that the control unit 86 of the vehicle navigation device 8 includes the time when the portable communication device 1 enters the vehicle 7 (that is, the user management area), the position of the own device, and the portable communication device 1 from the vehicle inside 7. The time when going outside and the position of the own device may be recorded in the storage unit 85. In order to realize such an operation, the control unit 86 executes a program 500 shown in FIG.

  In executing the program 500, the control unit 86 first determines in step 510 whether or not the mobile communication device 1 is wirelessly connected via the in-vehicle communication unit 82. If the wireless communication is established, the control unit 86 subsequently executes step 530. If the wireless communication is not established, a warning of misplacement of the portable communication device 1 is given at step 520.

  This misplacement warning is a notification for notifying the user that he / she has forgotten to bring the portable communication device 1 into the vehicle 7. This step 520 may be executed only when the own device is in a predetermined user management area (for example, a home parking lot or a workplace parking lot). It should be noted that whether or not the device is in the predetermined user management area depends on the coordinate range of the position corresponding to the user management area (recorded in advance in the storage unit 85) and a position such as GPS (not shown). The determination may be made based on a comparison with the current position of the own device specified based on the detector, or a vehicle outside short-range communication unit (not shown) may use a communication device having a user management area as a communication area (a storage unit in advance). Determination may be made based on whether or not communication is being performed.

  In step 530, the mobile ID of the connected mobile communication device 1 is recorded in the storage unit 85. Subsequently, in step 540, the current position of the own device (that is, the connection position of the portable communication device 1) and the current time (that is, the connection time of the portable communication device 1) are recorded in the storage unit 85 in association with the portable ID.

  Subsequently, in step 550, the wireless connection with the portable communication device 1 is waited until the wireless communication is disconnected. When the connection is disconnected, in step 560, the current position of the own device (that is, the disconnected position of the portable communication device 1) and the current The time (that is, the disconnection time of the portable communication device 1) is recorded in the storage unit 85 in association with the portable ID.

  In addition, after step 560, the memory | storage part 85 may shift to a sleep state, and the vehicle navigation apparatus 8 itself may stop.

  In this way, the user can confirm the record later to find out in which location and time the portable communication device 1 wirelessly connected to the vehicle navigation device 8 is disconnected, A clue for identifying the lost location of the portable communication device 1 to some extent can be obtained.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, in the above embodiment, narrow-area communication is shown as communication between the portable communication device 1 and the infrastructure side communication device. However, as communication between the portable communication device 1 and the infrastructure side communication device, Proximity communication (for example, communication using an RF tag or a wireless card) may be used.

  Further, the facility management server 3 is not necessarily required. In that case, it is only necessary that the infrastructure-side communication device transmits the forgotten thing state data directly to the forgotten thing server 5.

  In addition, the forgotten item server 5 may also create WEB data for notifying the existence area of the portable communication device 1 in the same manner as the facility management server 3, and make the WEB data accessible from communication devices on the wide area communication network 4. .

  In addition, the vehicle navigation device 8 receives a hard disk drive and other writable storage medium (for example, a flash memory) other than the hard disk drive (the startup is faster than the hard disk drive) as the storage unit 85. The forgotten item state data may be stored in a writable storage medium other than the hard disk drive. In this case, when receiving the approach signal from the user detection device 41, the control unit 86 may read the forgotten item state data from the other writable storage medium without operating the hard disk drive. In this way, it is possible to display in a short time after detecting the user.

  Further, even when the mobile communication device 1 is in the user management area, the processing in steps 230 to 290 may be performed. In this case, the set time in step 230 and the reference time in step 280 are set longer than those in the case outside the user management area, and the lock level in step 240 is compared with that in the case outside the user management area. It may be low.

  As described above, the mobile communication device 1 may transmit the forgotten item state data even when the mobile device 1 is in the user management area. Therefore, for example, in response to a case where the portable communication device leaves the user's management due to vehicle theft or the like, it is possible to transmit forgotten thing state data and to identify the position of the portable communication device.

  However, since the possibility of theft in the user management area is lower than the possibility of misplacement outside the user management area, the time used as the reference time in the user management area is longer in the former. As a result, in the user management area, it is possible to suppress transmission of unnecessary forgotten item state data to some extent while transmitting forgotten item state data. Further, since the lock level is set low in the user management area, the number of operation steps for unlocking is reduced.

  Further, when the portable communication device 1 detects that an operation to release the lock has been performed on the own device, the portable communication device 1 transmits a signal indicating that to the nearby infrastructure communication device (hereinafter referred to as an operation signal). It may be. The operation signal may include information on the failure / success of unlocking.

  Then, the infrastructure side communication device transmits the received operation signal to the facility management server 3, the facility management server 3 transmits the received operation signal to the forgotten item server 5, and the forgotten item server 5 transmits the received operation signal to the mobile communication. The notification destination communication device may transmit the operation signal to the user, and the notification destination communication device may notify the user of reception of the operation signal.

  Further, the power supply controller 42 may be configured to turn on only power supply to a necessary part of the vehicle navigation device 8. In that case, when receiving the forgotten item state data, only the power supply to the storage unit 85 and the control unit 86 may be turned on based on the reception start notification received from the outside communication unit 81. .

  Further, as in the above embodiment, the facility management server 3 may perform the process of converting the infrastructure ID into a specific location area, the infrastructure communication device itself, or the forgotten item server 5. It may be performed in the notification destination communication device.

  In addition, since various communication devices may be installed in each facility, the facility communication function data indicating which communication function (communication frequency, communication method) is used in which facility in the portable communication device 1. (Data used for initial communication processing) may be stored in the storage unit 16 in advance. In that case, the portable communication device 1 may be configured to set its own communication function in accordance with the communication function of the facility corresponding to the current position (for example, specified by a GPS receiver (not shown)). In addition, before entering each facility, the portable communication device 1 may download facility communication function data of the facility from a WEB server or the like of the facility in accordance with a user operation. Alternatively, the portable communication device 1 receives facility communication function data of the facility by proximity communication from a communication device installed at the entrance at the entrance of the facility, and communicates with the own communication device based on the received data. A function may be set.

  Further, when communication with the portable communication device 1 is interrupted, the infrastructure side communication device may record the time of the interruption.

  In addition, the lost communication state data transmitted from the portable communication device 1 and recorded in the infrastructure side communication device, the facility management server 3, the forgotten item server 5, and the notification destination communication device includes the lock level of the portable communication device 1, the portable communication device 1 The power remaining amount may be included.

  In addition, when the infrastructure communication device of the communication partner of the mobile communication device 1 changes, that is, when the mobile communication device 1 is moving, the possibility of theft is high. Therefore, in this case, the portable communication device 1 may be configured to invalidate a communication function other than the communication function for transmitting the position information to the forgotten item server 5, the notification destination communication device, or the like. Or the operation content with respect to the thief's portable communication device 1 may be transmitted to the forgotten item server 5, the notification destination communication device, etc. via the infrastructure side communication device. This increases the likelihood that the theft will be easier to identify.

  Further, the control unit 17 of the mobile communication device 1 may be configured to immediately execute Step 290 based on the positive determination result of Step 230 in FIG. 9.

  In the above embodiment, each function realized by each controller executing a program is realized by using hardware having those functions (for example, an FPGA capable of programming a circuit configuration). You may come to do.

  Moreover, in the said embodiment, although a navigation apparatus is a vehicle-mounted type, a navigation apparatus may be mounted in a ship and an airplane, and may be a thing of the type which a person can carry. . For example, a mobile phone having a navigation device function also corresponds to the navigation device of the present invention.
