Electronic device and gateway for network service, and operation method therefor

A method of operating a gateway, the method comprising:

• receiving space information displaying an image of a network device on a space drawing visualizing an indoor space, from an electronic device;
• storing the space information;
• and
• if receiving an execution instruction for controlling the network device from the electronic device, transmitting the execution instruction to the network device by using the stored space information.

An electronic device comprising:

• a display;
• a communication interface;
• and
• a processor controlling the display and the communication interface,
• wherein the processor is configured to:
• display a space drawing visualizing an indoor space and at least one icon related to an execution instruction to be transmitted to a network device,
• recognize that an icon selected among the displayed at least one icon is overlapped on an image of the network device comprised in the space drawing, and
• transmit the execution instruction corresponding to the selected icon, to the network device through the communication interface.

A gateway comprising:

• a communication interface;
• a memory;
• and
• a processor controlling the communication interface and the memory,
• wherein the processor is configured to:
• receive space information displaying an image of a network device on a space drawing visualizing an indoor space, from an electronic device through the communication interface,
• store the space information, and
• if receiving an execution instruction for controlling the network device from the electronic device, transmit the execution instruction to the network device by using the stored space information.
