  Next, a response message output process flow of the HGW 104 according to the second exemplary embodiment of the present invention will be described with reference to FIG. When a visitor presses the button of the door chime 101, a chime sound is output from the sound sensor signal input unit 201 in the house.

  The sound sensor signal input unit 201 receives a signal indicating that a chime sound has been detected from the sound sensor 103 that has detected the chime sound (S401). The sound sensor signal input unit 201 notifies the control unit 215 that the door chime 101 has sounded.

  Next, the control unit 215 that has received the notification inquires the terminal information management unit 203 about a terminal in a current communicable state (S402). The terminal information management unit 203 confirms whether or not the terminal registered in the registered terminal table 204 is in a communicable state, and registers the confirmation result in the terminal state table 205. Details of the registered terminal table 204 and the terminal state table 205 will be described later.

  The terminal information management unit 203 checks the terminal state table 205, and if there is a communicable terminal (S403: Yes), notifies the control unit 215 that there is a communicable terminal. Further, the terminal information management unit 203 may notify the control unit 215 of destination information regarding a terminal in a communicable state. The destination information may be a MAC address or an IP address, for example. Receiving the notification, the control unit 215 outputs a command for generating a visitor notification packet addressed to a terminal in a communicable state to the packet generation unit 207.

  Next, when receiving a command for generating a visitor notification packet, the packet generation unit 207 generates a visitor notification packet whose destination is a terminal in a communicable state (S404). Details of the visitor notification packet will be described later. The packet generation unit 207 outputs the generated visitor notification packet to the control unit 215.

  Upon receiving the visitor notification packet, the control unit 215 transmits the visitor notification packet to the terminal in a communicable state via the wireless / wired IF unit 202 (S405).

  In step S403, the terminal information management unit 203 checks the terminal state table 205, and if there is no terminal in a communicable state (S403: No), controls that there is no terminal in a communicable state. Notification to the unit 215.

  When control unit 215 receives notification that there is no terminal in a communicable state, control unit 215 determines that there is no resident in the house. In this case, the control unit 215 requests the response message management unit 209 for response message data that informs the visitor that the user is away. When the response message management unit 209 receives the request for the response message data, the response message management unit 209 selects, from the response messages stored in the voice data 210, the response message data that informs the visitor that the user is away, and the control unit The data is output to 215 (S406).

  Next, the control unit 215 outputs a response message (absence notification message) that informs the visitor that the user is away from the wireless speaker 108 outside the home (S407). The absence notification message is, for example, a message that outputs a voice message of “I am away now”.

  The wireless speaker 108 receives the response message data transmitted from the wireless / wired IF unit 202, and outputs the voice of the response message.

  In step S404, the packet generation unit 207 may set the destination of the visitor notification packet as a broadcast address, and add an identifier of the visitor notification packet and additional information of the visitor notification packet. In this case, the control unit 215 may transmit the visitor notification packet by broadcasting via the wireless / wired IF unit 202.

  Subsequently, the registered terminal table 204 and the terminal state table 205 according to the second embodiment of the present invention will be described with reference to FIG. In the registered terminal table 204, information on ID, terminal type, owner name or installation location, and MAC address is registered. Such information may be registered in advance by the user himself / herself using WebGUI or the like. As the owner name or installation location information, the owner name may be registered if the terminal is the portable terminal 105, and the installation location may be registered if the terminal is the PC 106 or the TV 107.

  The terminal state table 205 includes information on whether or not a terminal registered in the registered terminal table 204 is in a communicable state, and connection method information indicating whether a terminal in a communicable state is wireless connection or wired connection. These pieces of information are updated when the HGW 104 receives a signal indicating that a chime sound has been detected from the sound sensor 103, or is automatically updated at regular intervals.

  Next, the types of packets transmitted and received in the second embodiment of the present invention will be described using FIG. In the customer response system, the following three types of packets are transmitted and received between the HGW 104 and a terminal in a communicable state. The first is a visitor notification packet transmitted from the HGW 104 to all terminals in a communicable state, and the second is a terminal user that is transmitted from the communicable terminal to the HGW 104, and the terminal user handles the visitor. The third is a response completion packet indicating which terminal user sends a response to be transmitted from the HGW 104 to a terminal in a communicable state.

  These packets are formed using the Ethernet (registered trademark) frame format, and are communicated using a TCP / UDP private port number. When the dedicated software (application) necessary for the visitor response system is installed, the HGW 104, the mobile terminal 105, the PC 106, and the TV 107 use a common TCP / UDP private port number, so that packets used in the visitor response system can be transmitted. Transmission and reception are possible. Packet identifier information is set in these packets. When the HGW 104, the portable terminal 105, the PC 106, and the TV 107 that have installed software (application) necessary for the customer response system are received, the packet identifier included in the packet is confirmed, and the type of the packet is determined.

  When receiving the visitor notification packet or the response completion packet, the portable terminal 105, the PC 106, and the TV 107 acquire additional information data after confirming the packet identifier.

It is assumed that the portable terminal 105, the PC 106, and the TV 107 have previously installed software (application) necessary for the customer response system of the present invention. A terminal in which software (application) necessary for the visitor response system has been installed can output and display a visitor notification. The display of the visitor notification displays the time when the HGW 104 detects the notification by the chime and an inquiry as to whether to respond to the visitor. FIG. 8 shows that the time information when the HGW 104 detects the chime sound and a message prompting selection of whether or not to respond to the visitor are displayed on the screen of each terminal.

  Next, the flow of reception processing of response packets transmitted from the mobile terminal 105, the PC 106, and the TV 107 in the HGW 104 will be described using FIG. 9 and FIG.

  The HGW 104 has a timer 211, and the timer 211 operates when a visitor notification packet is transmitted. The wireless / wired IF unit 202 of the HGW 104 outputs the received packet to the control unit 215. The control unit 215 outputs the received packet to the packet analysis unit 208 and requests analysis of the packet type. The packet analysis unit 208 confirms the packet identifier of the received packet and confirms that the received packet is a response packet. When the control unit 215 receives a response packet within a predetermined time after the timer 211 of the HGW 104 is activated (S901: Yes), the packet analysis unit 208 indicates that the response packet has been received and the terminal ( Hereinafter, the MAC address of the response terminal is output to the control unit 215.

  Upon receiving the response packet and the MAC address of the response terminal, the control unit 215 outputs the MAC address of the response terminal to the terminal information management unit 203. The terminal information management unit 203 extracts response terminal information registered in the registered terminal table 204 and stores the extracted response terminal information in the response terminal information 206. The terminal information management unit 203 uses the terminal state table 205 to check whether there is a terminal in a communicable state other than the response terminal stored in the response terminal information 206. When there is a terminal in a communicable state other than the responding terminal (S902: Yes), the terminal information management unit 203 includes information described in the registered terminal table 204 regarding all the communicable terminals other than the responding terminal, Information described in the terminal status table 205 is output to the control unit 215 (S903).

  The control unit 215 that has acquired information regarding all terminals in a communicable state other than the responding terminal instructs the packet generation unit 207 to generate a response completion packet having destinations in all communicable terminals other than the responding terminal. Is output.

  When acquiring the response completion packet generation command, the packet generation unit 207 generates a response completion packet destined for all terminals in a communicable state other than the response terminal (S904). The packet generation unit 207 sets the destination of the response completion packet as the MAC address of the terminal in a communicable state, and adds the response completion packet identifier, the reception time of the response packet, the terminal type of the response terminal, the owner or the installation location additional information. Then, the generated response completion packet is output to the control unit 215.

  When the control unit 215 receives a response completion packet destined for all terminals in a communicable state other than the response terminal, the control unit 215 transmits the response completion packet and information on the connection method described in the terminal state table 205 to the wireless / wired IF.
