  The communication unit 12 transmits a plurality of information generated in the information acquisition unit 11. For example, the communication unit 12 may transmit information to the server device 30 via a mobile communication network managed by a mobile communication carrier. For example, the communication unit 12 connects to a mobile communication network via a wireless line using LTE (Long Term Evolution) defined by 3GPP. Alternatively, the communication unit 12 may be connected to the mobile communication network via a wireless line using a wireless LAN.

  Next, a configuration example of the server device 30 will be described. When the information selection unit 31 acquires a plurality of pieces of information indicating the environment around the communication device 10, the information selection unit 31 selects information usable in the communication device 20 from the plurality of pieces of information.

  The information that can be used in the communication device 20 corresponds to, for example, moving image information when the communication device 20 supports high-speed communication such as LTE. When the communication device 20 has a display, sensor information, moving image information, and still image information correspond to information that can be used in the communication device 20.

The available information can be selected and the selected information can be transmitted to the communication device 20. Accordingly, the communication device 20 can search for the communication device 10 using the information transmitted from the server device 30.

(Embodiment 2)
Next, a configuration example of the communication apparatus 10 according to the second embodiment of the present invention will be described with reference to FIG. The communication device 10 is a lost communication device as described in FIG.

  The communication device 10 includes an information acquisition unit 11, a communication unit 12, and a loss determination unit 13. The information acquisition unit 11 and the communication unit 12 are the same as those in FIG. The loss determination unit 13 determines whether or not the communication device 10 is in a lost state. Specifically, the loss determination unit 13 periodically communicates with the communication device 20 that is a terminal for searching for the communication device 10 by short-range wireless communication. In the regular communication, for example, data may be periodically transmitted / received between the communication device 10 and the communication device 20, and the communication device 10 periodically repeats an operation of connecting and disconnecting to the communication device 20. Also good.

  The short-range wireless communication may be, for example, Bluetooth (registered trademark), infrared communication, wireless LAN communication, or the like. The loss determination unit 13 may have a function of performing modulation and demodulation of an antenna and data in order to perform short-range wireless communication. Here, the flow of the loss determination process in the loss determination unit 13 will be described with reference to FIG. The loss determination process of FIG. 3 may be always performed while the communication apparatus 10 is powered on, or may be periodically executed at regular intervals.

  First, the loss determination unit 13 performs short-range wireless communication with the communication device 20 (S11). For example, the loss determination unit 13 periodically transmits data to the communication device 20 and receives a response signal for the transmitted data from the communication device 20. Next, the loss determination unit 13 determines whether or not short-range wireless communication is ongoing (S12). The short-range wireless communication is continuing is a state in which a response signal for data transmitted to the communication device 20 can be received, for example.

  If the loss determination unit 13 determines that short-range wireless communication is ongoing, the loss determination unit 13 repeats the process of step S12. For example, when it is determined that the short-range wireless communication is continuing, the loss determination unit 13 may repeat the process of step S12 after a predetermined time has elapsed. Furthermore, the loss determination part 13 may complete | finish a loss determination process, without performing the process of step S12, when the process of step S12 is performed a predetermined frequency | count.

  If it is determined that the short-range wireless communication is not continuing, that is, if the response signal for the data transmitted to the communication device 20 cannot be received, the loss determination unit 13 determines that it is lost (S13). The loss determination unit 13 may determine that the loss has occurred when a predetermined number of response signals cannot be received. Or the loss determination part 13 may determine with a loss state, when a predetermined number of response signals cannot be received continuously.

  Returning to FIG. 2, the loss determination unit 13 outputs a message indicating the loss state to the information acquisition unit 11 when determining the loss state. When the information acquisition unit 11 receives a message indicating the loss state from the loss determination unit 13, the information acquisition unit 11 acquires or generates information indicating the surrounding environment. For example, when the information acquisition unit 11 receives a message indicating that it is in a lost state from the loss determination unit 13, the information acquisition unit 11 starts an application that executes the camera function, and autonomously captures a still image or a moving image, or a still image and A moving image is shot, and an application that performs a microphone function is activated to start recording autonomously. The shooting time, number of shots, recording time, etc. executed by the information acquisition unit 11 may be determined in advance. Furthermore, the type of information indicating the surrounding environment generated by the information acquisition unit 11 may be determined in advance. Here, the information acquisition process in the information acquisition part 11 is demonstrated using FIG. The information acquisition process of FIG. 4 is executed when the loss determination unit 13 determines that the information is lost.

  First, the information acquisition unit 11 determines whether or not it is a setting for taking a picture when it is in a lost state (S21). If the information acquisition unit 11 is in a lost state and determines that the setting is to take a photo, the information acquisition unit 11 takes a photo using the camera function (S22). If the information acquisition unit 11 determines that it is not set to take a picture in the lost state, the information acquisition unit 11 proceeds to the process of step S23.

  In step S21, when the information acquisition unit 11 determines that it is not set to take a photo when it is in a lost state, and after the information acquisition unit 11 takes a photo in step S22, the information acquisition unit 11 It is determined whether or not the setting is for shooting a moving image (S23).

  If the information acquisition unit 11 determines that the setting is to shoot a moving image in the lost state, the information acquiring unit 11 shoots a moving image using the camera function (S24). If the information acquisition unit 11 determines that the setting is not to shoot a moving image in the lost state, the information acquisition unit 11 proceeds to the process of step S25.

  In step S23, when the information acquisition unit 11 determines that the setting is not to shoot a moving image when it is in a lost state, and after the information acquisition unit 11 shoots a moving image in step S24, the communication unit 12 acquires It is determined whether there is information that has been completed (S25).

  If it is determined that there is information acquired by the information acquisition unit 11, the communication unit 12 transmits the information acquired by the information acquisition unit 11 to the server device 30 (S26). If the communication unit 12 determines that there is no information acquired by the information acquisition unit 11, the communication unit 12 ends the process.

  In FIG. 4, the example in which the information acquisition unit 11 determines whether or not there is a setting for taking a picture and whether or not the setting is for taking a moving picture has been described. Other operations may be performed.

  For example, as illustrated in FIG. 5, the information acquisition unit 11 may determine whether or not the setting is to record a voice when it is in a lost state (S31). In step S31, when the information acquisition unit 11 is in a lost state, the sound around the communication device 10 is recorded using the microphone function (S32). Step S33 and subsequent steps are the same as step S25 and subsequent steps in FIG. Furthermore, as shown in FIG. 6, the information acquisition unit 11 may determine whether or not the setting is for acquiring sensor information when the information is in a lost state (S <b> 41). The sensor information may be, for example, light amount measurement information, temperature measurement information, or other detected information. Step S43 and subsequent steps are the same as step S25 and subsequent steps in FIG.

  The processing of FIGS. 5 and 6 may be executed in combination with the processing of FIG. That is, in the process of FIG. 4, the information acquisition unit 11 may record sound and acquire sensor information after taking a photograph and a moving image.

  Next, a configuration example of the server device 30 according to the second embodiment of the present invention will be described with reference to FIG. The server device 30 includes an information selection unit 31, a communication unit 32, a communication device DB 33, and an acquisition information storage unit 34. The information selection unit 31 and the communication unit 32 are the same as those in FIG.

  When the information selection unit 31 acquires information indicating the surrounding environment from the communication device 10, the information selection unit 31 stores the acquired information in the acquisition information storage unit 34. The acquired information storage unit 34 may be a memory device provided in the server device 30 or may be a memory device connected to the server device 30 as an external device.

  The information selection unit 31 uses the communication device DB 33 to extract a communication device registered as a communication device that searches for the communication device 10 and identifies the type of information that can be used in each communication device. The information selection unit 31 extracts, for example, a smartphone terminal, a general mobile phone, a mobile router, and a home gateway as communication devices that search for the communication device 10.

  A general mobile phone is a mobile phone excluding a smartphone terminal, and is a mobile phone that performs communication via a 3G wireless line or the like. A mobile router is a device that does not have, for example, a display unit and a button operation unit and relays communication between a smartphone terminal and a mobile communication network, or between a general mobile phone and a mobile communication network. . The home gateway is a device that is connected to a plurality of communication devices in the home and is used when remotely controlling the plurality of communication devices in the home. Alternatively, the home gateway is a device that aggregates a plurality of communication devices and is used as a relay device when a home communication device operates another communication device in the home. The in-home communication device includes, for example, a smart phone terminal, a general mobile phone terminal, a home appliance having a communication function, and the like.

  The information selection unit 31 extracts from the acquired information storage unit 34 information that can be used in a communication device registered as a communication device that searches for the communication device 10. The information selection unit 31 outputs the information extracted from the acquired information storage unit 34 to the communication unit 32. Here, information managed in the communication device DB 33 will be described with reference to FIG. In this figure, it has shown that the smart phone terminal and the home gateway can utilize all moving image information, image information, audio | voice information, and sensor information. Furthermore, it is shown that a general mobile phone can use image information, audio information, and sensor information. Furthermore, the mobile router indicates that no information can be used.

  For example, when a smartphone terminal is compatible with a high-speed wireless line such as LTE and a general mobile phone is not compatible with a high-speed wireless line, the general mobile phone cannot use moving image information. In addition, when the mobile router does not have a display unit, a microphone, or the like, it is assumed that all of the moving image information, image information, audio information, and sensor information cannot be used.

  Returning to FIG. 7, the communication unit 32 transmits usable information for each communication device that searches for the communication device 10. Here, the flow of transmission processing in the server device 30 will be described with reference to FIG.

  First, the information selection unit 31 acquires information indicating the environment around the communication device 10 transmitted from the communication device 10, and stores the acquired information in the acquisition information storage unit 34 (S51). For example, it is assumed that the information selection unit 31 acquires moving image information, still image information, audio information, and sensor information from the communication device 10. Next, the information selection part 31 selects the information transmitted for every communication apparatus which searches the communication apparatus 10 (S52). For example, the information selection unit 31 selects moving image information, still image information, audio information, and sensor information as information to be transmitted to a smartphone terminal that searches for the communication device 10.

  Next, the information selection unit 31 determines whether there is a communication device that has not selected information for a communication device that searches for the communication device 10 (S53). For example, when the information selection unit 31 selects only information to be transmitted to a smartphone terminal, a general mobile phone, a mobile router, and a home gateway remain as unprocessed communication devices. In step S53, the information selection part 31 repeats the process of step S52, when an unprocessed communication apparatus remains.

  When the information selection unit 31 selects information to be transmitted to each of the smartphone terminal, the general mobile phone, the mobile router, and the home gateway, the communication unit 32 sets the information selected by the information selection unit 31 to each communication device. (S54).

  A process when the information selection unit 31 selects information to be transmitted to the mobile router in step S52 will be described in detail. According to the information managed in the communication device DB 33, the mobile router has no information that can be used. Therefore, the information selection unit 31 may transmit information specifying the operation in the mobile router to the mobile router via the communication unit 32. Specifically, the information specifying the operation in the mobile router may be, for example, contents such as blinking an LED or vibrating the apparatus main body in the mobile router. When the mobile router receives the information specifying the operation, the mobile router executes the specified operation. A user operating the mobile router can recognize that the communication device 10 is in a lost state by confirming the operation of the mobile router.

  As described above, by using the communication device 10 according to the second embodiment of the present invention, information indicating the environment around the communication device 10 that can be used when searching for the communication device 10 is collected or Can be generated. Furthermore, the server device 30 can select information available in the communication device 20 that searches for the communication device 10 from the information transmitted from the communication device 10, and can transmit the selected information to the communication device 20. .

  In addition, the server device 30, in the information transmitted from the communication device 10, if there is no information that can be used in the communication device 20, information that specifies an operation indicating that the communication device 20 is in a lost state. Can be sent. Thus, the communication device 20 can notify the user who operates the communication device 20 that the communication device 10 is in a lost state by executing the designated operation.

  In the above description, the home gateway device has been described as the communication device 20, but a home gateway device may be used instead of the server device 30. For example, the communication device 10 transmits information indicating the generated surrounding environment to the home gateway device. At this time, the home gateway may select information usable in the connected communication device and transmit the selected information to each communication device.

  For example, a home appliance having a communication function such as a television device or a refrigerator is assumed to be connected to the home gateway device. In such a case, the user who operates each household electrical appliance by transmitting information usable in each household electrical appliance among the information transmitted from the communication device 10 to the home gateway device by the home gateway device. On the other hand, information necessary for searching the communication device 10 can be notified. For example, the home gateway device may transmit moving image information and sensor information to the television device, and may transmit audio information to the fixed telephone.

  The home gateway device can receive even when a large amount of information such as moving image information is transmitted from the communication device 10 by connecting to the Internet via an optical communication line or the like. In addition, the home gateway device and each home appliance may be connected via a wireless LAN communication line.

  In the above-described embodiments, the present invention has been described as a hardware configuration, but the present invention is not limited to this. The present invention can also be realized by causing a CPU (Central Processing Unit) to execute a computer program by performing the processing described with reference to FIGS. )

  In the above example, the program can be stored and supplied to a computer using various types of non-transitory computer readable media.
