The middleware 153 and the web software (CoAP) 156 may be located above the embedded OS (RTOS) 159 including a UDP stack for transmitting data based on 802.11 and IP, which is a wireless LAN standard.

The WoT proxy 110 (hereinafter, referred to as a proxy) connects an internal home network and an external home Internet network, and serves as a gateway. The proxy 110 includes a CoAP library 169 for communication with the electronic device 100, a middleware 163 for device management, and an HTTP-based micro web server/client (MWS/ C) (166). In addition, it may include a WoT proxy module (WoT Proxy) 160 for delivering the HTTP-based message to the electronic device 100 as a CoAP protocol, and the WoT proxy module 160 delivers the message from the device to the CoAP. It can also support the HTTP-based delivery of the received message to an external service node. In this case, the proxy platform may use any operating system as long as it can accommodate UDP and TCP protocols for transmitting data based on IP.

The cloud server 120 (hereinafter, the server) may communicate with the proxy 110 and provide an open application program interface (API) to the outside. It is possible to monitor and manage the electronic device 100 based on HTTP through the Internet network, and a web server/client (Web Server/Client) 173 and application service (WoT Service) that can provide this function as an open API. (170). For the server platform, any operating system can be used as long as it can accommodate the IP-based TCP protocol, and HTTP, which is a general web communication protocol, must be able to be used above the TCP protocol.

The middleware protocol used in the present invention defines URI, Method (Get, Put, Delete, Post), and payload (Paylaod) by utilizing Restful-based CoAP protocol and HTTP protocol, and the server 120 actively transmits the message. A simple binary protocol for UDP broadcasting can be included to solve the constraint of the CoAP protocol of the undeliverable server/client structure. At this time, method is for discovery, advertisement, authentication, etc., get is for discovery, registration, information, event, and put is used for advertisement, discovery, registration, information, event, control, authentication, etc. The WoT home appliance 100 may use various protocols such as MQTT-S (MQ Telemetry Transport For Sensors), which is a protocol for machine-to-machine communication.

3 is a flowchart illustrating an initial setting method of a home network system according to an embodiment of the present invention.

Referring to FIG. 3 , the user creates an account on the server 120 using the terminal 130 ( 300 ), and in this case, the user downloads the app using a QR code or NFC function in the electronic device 100 . After doing so, the user's ID and password, user phone number information, and the like may be registered in the server 120 .

Also, when power is first turned on, the electronic device 100 generates a unique service set identifier (SSID) and operates in a software access point (AP) mode ( 303 ). The terminal 130 inputs the SSID of the electronic device 100 to access the electronic device 100. At this time, when the electronic device 100 transmits an advertisement message to the terminal 130 (305), the terminal 130 An advertisement message is transmitted to the electronic device 100 ( 310 ). The terminal 130 may know the SSID of the electronic device 100 in advance, and may use a password if necessary.

After the terminal 130 and the electronic device 100 are connected, they transmit and receive information for initial setting ( 315 and 320 ). For example, the information for initial setting includes a unique code of the electronic device 100 , an SSID of the proxy 110 , and The password, the ID and password registered by the terminal 130 in the server 120, information about the terminal 130, and the like. The SSID and password of the proxy 110 are transmitted by the terminal 130 to the electronic device 100. For example, the user may input the SSID and password of the proxy 110 through an application application of the terminal 130, , the inputted information may be transmitted to the middleware of the electronic device 100 through the middleware of the terminal 130 .

When the terminal 130 and the electronic device 100 transmit and receive initial setting information, the terminal 130 and the electronic device 100 access the proxy 110 using the SSID and password of the proxy 110 (325,330), The terminal 130 accesses the server 120 through the proxy 110 (333). In this case, when the proxy 110 transmits an advertisement message to the electronic device 100 ( 335 ), the electronic device 100 transmits the advertisement message to the proxy 110 ( 340 ).

The proxy 110 checks whether the electronic device 100 is registered with the proxy 110. If not registered, the proxy 110 requests information for registration from the electronic device 100 (343), and the electronic device 100 When information for registration is transmitted ( 345 ), the electronic device 100 is registered ( 347 ).

After registering the electronic device 100 , the proxy 110 transmits a registration status update message to the electronic device 100 ( 350 ), and the electronic device 100 transmits a response message thereto to the proxy 110 ( 355 ) ). Also, the proxy 110 requests the server 120 to register the electronic device 100 and transmits information for registration (360), and the server 120 completes the registration of the electronic device 100 (363). ), and transmits a registration completion message to the proxy ( 370 ), at this time, the server 120 may transmit a message regarding the registration of a new device informing the terminal 130 that the electronic device 100 is registered with the server 120 . There is (365). When the proxy 110 receives the registration completion message from the server 120 , it requests the electronic device 100 to update the registration status ( 375 ), and the electronic device 100 transmits a response message to the proxy 110 . (380). When the proxy 110 receives a response message to the registration status update from the electronic device 100 , the proxy 110 transmits a message regarding registration of a new device informing the server 120 that the electronic device 100 is registered to the terminal 130 . This may be used when the server 120 does not transmit a message regarding registration of a new device to the terminal 130 .

Meanwhile, the terminal 130 transmits information for user authentication to the server 120 ( 385 ), and the server 120 uses the information for user authentication received from the terminal 130 to complete server authentication ( 391). When the authentication is completed, the server 120 transmits the information for user authentication received from the terminal 130 to the proxy 110 (390), and the proxy 110 sends an authentication completion message after completing the authentication (393). It transmits to the server 120 (395), and the server 120 transmits an authentication completion message to the terminal 130 (399). In this case, the information for user authentication is, for example, a unique code of the electronic device 100 , a user ID and password, and the like.
