Ultimately, the home gateway 200 can perform USB communication-based IP communication through the access point 100 connected via the USB interface 210. [

The USB interface 210 receives power from the USB interface 140 of the access point 100 connected via the USB interface 210 and transmits the power to the power supply unit 240. Accordingly, since the home gateway 200 does not need to receive a separate external power supply, it is not necessary to use a power adapter for supplying the external power.

The IoT interface 220 is connected to various external IoT devices 400 via wired or wireless lines and enables communication connection to the external service server 300 and the IoT devices 400 to be connected. The IoT interface 220 can perform communication with a plurality of IoT devices 400 through various communication methods such as Z-WAVE, Bluetooth, and Zigbee in various wired and wireless communication schemes .

At this time, the communication control unit 230 performs IP communication using the USB driver as in the access point 100.

The structure of the protocol stack between the access point 100 and the home gateway 200 for implementing the IP communication by implementing the Ethernet communication through the USB driver by the communication control unit 230 and the access point 100 Is shown in FIG. 4, the access point 100 and the home gateway 200 implement Ethernet communication (Ethernet over USB) in the USB driver layer, respectively, so that the access point 100 and the home gateway 200 can communicate with each other through the Ethernet communication, IP communication between the mobile terminals 200 can be performed. At this time, the access point 100 may need to confirm whether the home gateway 200 performing the IP communication through the USB driver is a normal device.

In addition, the communication control unit 230 transmits a message between the service server 300 and the IOT device 400. At this time, the communication control unit 230 may further include a message delivery unit 231 for delivering a message.

The message transfer unit 231 transfers a message transmitted from the service server 300 directly to the IoT device 400 or transmits a message transmitted from the IoT device 400 to the service server 300 . Here, the message delivery unit 231 may include a protocol used for communication with the service server to directly control the IoT terminal including the terminal management and command control system for the IoT device by the existing home gateway in the embodiment of the present invention Can be used. At this time, in the existing protocol, in particular, in the packet header, it is necessary to specifically specify the format of the message transmitted between the home gateway and the service server. However, in the embodiment of the present invention, It is only required to transmit the message of the service server 300 to the IoT device 400 and to transmit the message of the IoT device 400 to the service server 300 without performing the control for the IoT device 400, It is possible to minimize the processing in the home gateway 200 by directly including the messages received from the service server 300 and the IOT device 400 in the Extension Field without using the format definition.

Table 1 below shows an example of a packet header when the home gateway 200 and the IOT device 400 use Z-WAVE communication.

[Table 1]

However, as in the example of Table 1, it is possible to identify an identifier capable of identifying the IoT device 400 to receive the message delivered from the service server 300 in the extension field of the packet header Only an edge node id and an identification field (Z-Wave Result Code) indicating a result code transmitted from the IoT device 400 need to be specified. These extension fields are shown in bold in [Table 1].

The power supply unit 240 receives external power through the USB interface 210, that is, power supplied from the access point 100, and uses it as a power supply in the home gateway 200. Accordingly, the home gateway 200 does not have a power adapter for receiving a separate external power source.

Therefore, when a new IoT device or a non-IP communication IoT device is connected to the home gateway 200, only when the device manager 320 performs an update to add information on newly connected IoT devices, the home gateway 200 It is possible to control the IOT device 400 newly connected to the home gateway 200 in the service server 300 without performing any additional firmware update in the home gateway 200.

The lower interworking middleware 330 has an adapter that can be accommodated regardless of the protocol of the IoT device 400 connected to the lower device, that is, the home gateway 200 connected through the IP communication. The communication between the upper service and the lower apparatus 400 is enabled. At this time, the adapter includes a wireless device standard adapter 231 that performs connection to a wireless IoT device and a wired device standard adapter 232 that performs a connection to a wired IoT device.
