1 Embodiment 1
Here, the communication system 10 of this embodiment is demonstrated, referring FIG. 1 and FIG.

1.1 Configuration As shown in FIG. 1, the communication system 10 includes a communication device 20, a control device 30 (first device), a server device 40 (second device), and a storage device 50.

  The communication device 20 and the control device 30 are installed, for example, in the same house, and the communication system 10 is a system that checks the status (such as safety) of the resident of the house where the communication device 20 and the control device 30 are installed. is there.

  The communication device 20 is driven by, for example, a battery, and the control device 30 is driven by receiving power supply from a commercial power source. In addition, wireless communication (first wireless communication) using radio waves as a transmission medium is performed between the communication device 20 and the control device 30. Here, in the first wireless communication between the communication device 20 and the control device 30, data with a relatively small amount of data is packetized and transmitted and received wirelessly. The first wireless communication is communication using a wireless communication method (first communication method) whose communication speed is lower than communication via the public network 12 described later.

  As shown in FIG. 1, the control device 30 is connected to a server device 40 via a network 11 such as the Internet. The network 11 is not limited to the Internet. For example, the network 11 may be any technology that enables communication between the control device 30 and the server device 40.

  The communication device 20 has a cellular communication function for connecting to the public network 12 shown in FIG. Here, the public network 12 is, for example, a mobile phone line network (3G line network, 4G line network) used for communication of a mobile phone. Further, the cellular communication function is not normally activated, and is activated by a request from the server device 40. The cellular communication function includes a call function for making a call via the public network 12 and a packet communication function for transmitting and receiving packetized data (voice data and image data) via the public network 12.

  The server device 40 transmits a cellular communication start instruction that instructs the start of the second wireless communication (cellular communication) via the public network 12 to the control device 30 via the network 11. Here, the cellular communication has a higher communication speed than the communication using the first communication method described above, and is a communication method (second communication) capable of transmitting / receiving data having a larger data amount than the data used in the first communication method. Communication). In addition, prior to transmission of the cellular communication start instruction, the server device 40 writes information (communication information) necessary for cellular communication in the text, and sends mail (stored data) with the destination as the communication device 20 to a short mail service. (SMS) is used to transmit via the public network 12. Here, the communication information includes either information indicating that communication is performed using a call function or information indicating that communication is performed using a packet communication function. The information indicating that communication by the call function is performed is telephone number information indicating the telephone number of the server device 40, for example. The information indicating that communication is performed using the packet communication function is, for example, address information indicating the IP address of the server device 40.

  In the short mail service, mail is stored in the storage device 50 when the mail destination device is not in a state of receiving mail, for example, when a mail receiving function (cellular communication function) is not activated. In the present embodiment, since the normal cellular function is not activated in the communication device 20, mail transmitted from the server device 40 using the short mail service is temporarily stored in the storage device 50.

  When receiving the cellular communication start instruction from the server device 40, the control device 30 transmits activation request information for requesting activation of the cellular communication function to the communication device 20 by the first wireless communication described above.

  When receiving the activation request information from the control device 30, the communication device 20 activates the cellular communication function and connects to the public network 12. When connected to the public network 12, the communication device 20 uses the short mail service to receive mail from the server device 40 stored in the storage device 50 via the base station 13. The communication device 20 selects either communication using the call function or communication using the packet communication function according to the content of the communication information, and communicates with the server device 40 using the selected function.

  Thus, as shown in FIG. 1, the communication device 20 communicates with the server device 40 through the first route 15 with the control device 30 interposed therebetween, and is a route using the public network 12, and the first route Communication with the server device 40 is performed via a second path 16 different from 15.

  Thereby, the server apparatus 40 can acquire data, such as a resident's audio | voice and an image, from the communication apparatus 20 using cellular communication.

  Next, the communication device 20, the control device 30, the server device 40, and the storage device 50 will be described in detail.

(1) Communication device 20
As illustrated in FIG. 1, the communication device 20 includes a first communication unit 21, a second communication unit 22, a control unit 23, a voice input unit 24, a photographing unit 25, a voice output unit 26, and a display unit 27. The communication device 20 includes a processor and a memory, and the function of the control unit 23 is realized by the processor executing a program stored in the memory.

  The first communication unit 21 is a communication device that performs first wireless communication with the control device 30 via the antenna 21a. When receiving the activation request information from the control device 30, the first communication unit 21 outputs an activation request for the second communication unit to the control unit 23.

  The second communication unit 22 is a communication device that performs cellular communication by using the public network 12 via the antenna 22a. When cellular communication is not performed, power is not supplied to the second communication unit 22. When the second communication unit 22 is activated by the control unit 23 to be described later, the second communication unit 22 automatically performs processing related to preparation for connection with the public network 12 such as preparation for connection with the base station 13 (connection preparation processing) A location request process for requesting device registration or the like is performed. When the connection with the public network 12 is completed, the second communication unit 22 receives the mail from the server device 40 stored in the storage device 50 via the base station 13. The second communication unit 22 communicates with the server device 40 by cellular communication using one of a call function and a packet communication function corresponding to the content of the communication information described in the text of the received mail.

  Thereby, since the 2nd communication part 22 can transmit / receive the data larger than the data transmitted / received by the 1st communication part 21, such as an image and an audio | voice, power consumption is larger than the 1st communication part 21. FIG.

  The control unit 23 controls the overall operation of the communication device 20. When receiving the activation request from the first communication unit 21, the control unit 23 activates the second communication unit 22, for example, starts supplying power to the second communication unit 22.

When communication with the server device 40 is established, the second communication unit 22 is caused to perform communication with the server device 40 using audio data. Specifically, the control unit 23 controls the second communication unit 22 so that the audio data received from the audio input unit 24 is transmitted to the server device 40 by the second wireless communication. Further, the second communication unit 22 is controlled to receive the audio data transmitted from the server device 40. When the control unit 23 receives the audio data transmitted from the server device 40 via the second communication unit 22, the control unit 23 outputs the received second audio data to the audio output unit 26.

  When the packet communication function is used, the control unit 23 performs packet communication with the server device 40 by the second wireless communication using the IP address represented by the address information, that is, the server device 40 as the destination. Let the unit 22 perform it. For example, the control unit 23 controls the second communication unit 22 so that the audio data received from the audio input unit 24 and the image data received from the imaging unit 25 are transmitted to the server device 40 by the second wireless communication. In addition, the control unit 23 controls the second communication unit 22 so as to receive the audio data and the image data transmitted from the server device 40. When the control unit 23 receives the audio data transmitted from the server device 40 via the second communication unit 22, the control unit 23 outputs the received audio data to the audio output unit 26. When the control unit 23 receives the image data transmitted from the server device 40 via the second communication unit 22, the control unit 23 outputs the received image data to the display unit 27.

  The voice input unit 24 is, for example, a microphone, and outputs voice data based on the input voice to the control unit 23 when a resident's voice is input.

  The imaging unit 25 is a camera, for example, and outputs image data based on the captured image (still image, moving image) to the control unit 23.

  The audio output unit 26 is a speaker, for example, and outputs audio based on audio data.

  The display unit 27 is a display such as a liquid crystal or EL (electroluminescence), and outputs an image based on the image data.

  Note that the communication device 20 does not have to include all of the audio input unit 24, the imaging unit 25, the audio output unit 26, and the display unit 27. For example, when only communication of audio data is performed, the communication device 20 only needs to include the audio input unit 24 and the audio output unit 26. When only communication of image data is performed, the communication device 20 includes: What is necessary is just to provide the imaging | photography part 25 and the display part 27. FIG.
