The arrival confirmation information transmission unit 33 transmits the arrival confirmation information to the gateway device 2 at a predetermined timing via the first communication unit 32. More specifically, when the mobile communication device 1 is located in the residence H, the arrival confirmation information transmission unit 33 uses the mobile communication device 1 via the first wireless LAN interface 35 of the first communication unit 32. Is located outside the residence H, the arrival confirmation information is transmitted to the gateway device 2 at a predetermined timing via the mobile communication interface 34 of the first communication unit 32.

The predetermined timing at which the arrival confirmation information transmission unit 33 transmits the arrival confirmation information is determined by the determination unit 43 of the gateway device 2 described later, that the mobile communication device 1 is located inside the residence H or is located outside the residence H. It is synchronized with the timing of determining whether or not to perform, and more specifically, it is a cycle in which the position of the mobile communication device 1 should be confirmed. This timing may be set arbitrarily, but as an example, it is set every hour.

The arrival confirmation information transmitted by the arrival confirmation information transmission unit 33 is that the determination unit 43 of the gateway device 2 has received from the mobile communication device 1, such as a ping request in an IP (Internet Protocol) network. It may be a specific packet that can be discriminated, but preferably, this arrival confirmation information can be received only by the specific gateway device 2 (that is, the specific second communication unit 42). In this case, the arrival confirmation information is preferably a packet containing the global IP address of the gateway device 2 to which the arrival confirmation information should be received as a destination.

Further, the control unit 40 of the present embodiment has a timer function capable of measuring a predetermined time.

When the arrival confirmation information described above is received by the second communication unit 42, the determination unit 43 moves based on whether the arrival confirmation information is received by the external communication interface 46 or the second wireless LAN interface 47. It is determined whether the body communication device 1 is located inside or outside the residence H.

The determination method by the determination unit 43 is arbitrary, but as an example, the arrival confirmation information includes information for identifying the mobile communication device 1, for example, information of a unique MAC address included in the first communication unit 32. If so, information regarding whether the external communication interface 46 or the second wireless LAN interface 47 of the second communication unit 42 receives the arrival confirmation information when the second communication unit 42 receives the arrival confirmation information. Is temporarily stored in the storage unit 41 in association with this MAC address, and a method of determining based on this information stored in the storage unit 41 can be mentioned.

Here, in the determination unit 43, the mobile communication device 1 communicates with the gateway device 2 via the second wireless LAN interface 47, and further, the second communication unit 42 (more specifically, the second wireless LAN interface 47). ), It is preferable to determine that the mobile communication device 1 is located in the residence H.

Here, that the authentication by the second communication unit 42 is performed means that the second communication unit 42 of the gateway device 2 responds to the Probe Request packet from the first communication unit 32 of the mobile communication device 1. From the state in which the Probe Response packet was transmitted from, the state in which the authentication by the specified authentication method (WPA (WiFi Protected Access) 2) is completed, preferably, the association is followed by the authentication. The request and response have been completed.

That is, the second communication unit 42 of the gateway device 2 receives the probe request packet from the first communication unit 32 of the mobile communication device 1, and subsequently receives the arrival confirmation information from the mobile communication device 1. If the determination unit 43 determines that the mobile communication device 1 is located in the residence H by the reception of the communication unit 42 of the above, even if the mobile communication device 1 simply passes through the residence H, this movement There is a possibility that the mobile communication device 1 will be determined to be located in the residence H. It takes a certain amount of time for the authentication by the second communication unit 42 to be completed, and if the mobile communication device 1 is located in the residence H for this amount of time, the determination unit 43 This is because it is considered that there is no problem even if it is determined that the mobile communication device 1 is located in the residence H.

The notification unit 44 notifies the determination result by the determination unit 43 to the contact information stored in the address management table 50. There is no particular limitation on the notification method by the notification unit 44, and as an example, when the contact information is an e-mail address, the notification unit 44 has a mailer (e-mail software) function and is addressed to the e-mail address which is the contact information. Examples thereof include a method of sending and notifying an e-mail in which information about whether the mobile communication device 1 is determined to be located inside the residence H or outside the residence H is described in the text. Alternatively, when the contact information is a telephone number, the notification unit 44 has a function of generating an automatic voice like an automatic voice response device (IVR: Interactive Voice Response), and automatically addresses the telephone number which is the contact information. An example is a method of notifying the determination result of the determination unit 43 by voice. Furthermore, there is also a method of sending a message to the contact information (account) of SNS (Social Network Service).

Here, when the determination result by the determination unit 43 is different from the latest determination result by the determination unit 43, the notification unit 44 preferably notifies the determination result to the contact information. That is, as described above, the mobile communication device 1 transmits the arrival confirmation information at a predetermined timing, and the determination unit 43 makes a determination when the second communication unit 42 receives the arrival confirmation information. It is possible that the mobile communication device 1 is continuously located inside or outside the residence H, and the determination results do not differ for a certain period of time. In this case, the notification unit 44 will notify the same determination result to the contact information, and the person who receives the determination result or the like may feel complicated. Therefore, if the determination result of the determination unit 43 is different from that immediately before, and the notification unit 44 is configured to notify the contact information, the mobile communication device 1 moves from the inside of the residence H to the outside of the residence H, or On the contrary, when the user moves from outside the residence H to inside the residence H, the determination result or the like can be received, and the possibility of making an appropriate determination can be increased.

The acquisition unit 45 acquires the position information of the mobile communication device 1 at the time when the arrival confirmation information is transmitted. That is, as described above, when the position information of the mobile communication device 1 is included in the arrival confirmation information, the acquisition unit 45 acquires the position information of the mobile communication device 1 included in the arrival confirmation information. Alternatively, when the mobile communication device 1 is configured to transmit the position information of the mobile communication device 1 at the same time as the transmission of the arrival confirmation information, in addition to the arrival confirmation information, it is transmitted from the mobile communication device 1. Get location information. It is preferable that the position information acquired by the acquisition unit 45 is temporarily stored in the storage unit 41.

Then, it is preferable that the notification unit 44 notifies the location information to the contact information together with the determination result.

Further, it is preferable that the acquisition unit 45 converts the location information into the address information, and the notification unit 44 notifies the address information together with the determination result to the contact information. There is no particular limitation on the method of converting the location information into the address information, and there is a method of providing the location information to a known server (not shown) existing on WAN4 and providing the address information from this server. ..

Further, when the determination result by the determination unit 43 is the determination result that the mobile communication device 1 is located in the residence H, the acquisition unit 45 can acquire the operation history of the mobile communication device 1. preferable. That is, as described above, when the operation history of the mobile communication device 1 is included in the arrival confirmation information, the acquisition unit 45 acquires the operation history of the mobile communication device 1 included in the arrival confirmation information. Alternatively, when the mobile communication device 1 is configured to transmit the operation history of the mobile communication device 1 at the same time as the transmission of the arrival confirmation information, in addition to the arrival confirmation information, it is transmitted from the mobile communication device 1. Get the operation history. It is preferable that the operation history acquired by the acquisition unit 45 is temporarily stored in the storage unit 41.

Then, it is preferable that the notification unit 44 notifies the contact information of information on whether or not the mobile communication device 1 has been operated within a certain period of time together with the determination result. This fixed period can be arbitrarily set, but as an example, it is the operation history of the day when the determination unit 43 makes a determination.

In this way, even when it is determined that the mobile communication device 1 is located in the residence H, the owner of the mobile communication device 1 cannot operate the mobile communication device 1, for example, due to physical condition. If the mobile communication device 1 is simply located in the residence H when the mobile communication device 1 cannot get out of the bed for a long time, it is premature to judge that the owner is living in peace. Therefore, the notification unit 44 notifies the contact information of information on whether or not the mobile communication device 1 has been operated within a certain period of time, so that the person who receives the determination result or the like refers to this information. Therefore, the state of the owner of the mobile communication device 1 can be determined more appropriately.

Further, it is preferable that the notification unit 44 notifies the mobile communication device 1 when the second communication unit 42 cannot receive the arrival confirmation information from the mobile communication device 1 at a predetermined timing. In addition, when the second communication unit 42 cannot receive the arrival confirmation information from the mobile communication device at a predetermined timing, the notification unit 44 preferably notifies the contact information.

When the second communication unit 42 cannot receive the arrival confirmation information from the mobile communication device 1 at a predetermined timing, the mobile communication device 1 is located outside the service area of the mobile communication network 3. Is in a power-off state, etc., and there is an increasing need to confirm the whereabouts of the owner of the mobile communication device 1. Therefore, it is preferable that the notification unit 44 notifies the mobile communication device 1 or, in addition, the notification unit 44 notifies the contact information at an early stage to prompt appropriate subsequent measures.
