Method and apparatus for smart home service based on cloud

A gateway, comprising:

• a data relay managing unit to relay transmission and reception of data between a first network and a second network,
• wherein the data relay managing unit receives a user request generated by a first terminal from a virtual smart home service apparatus that is connected over the first network, transmits the user request to a second terminal connected over the second network, receives information associated with the second terminal from the second terminal, and transmits information associated with the second terminal to the virtual smart home service apparatus,
• the virtual smart home service apparatus is generated through a virtualization technology of a server, and
• the first network and the second network are different from each other.

A method of providing a smart home service in a virtual smart home service apparatus generated through a virtualization technology of a server, the method comprising:

• receiving a user request from a first terminal;
• converting a first protocol of the user request to a second protocol;
• and
• transmitting the user request converted to the second protocol to a gateway,
• wherein the second protocol is a protocol capable of communicating with a second terminal connected to the gateway.

A method of providing a smart home service in a gateway relaying transmission and reception of data between a first network and a second network, the method comprising:

• receiving a user request generated by a first terminal from a virtual smart home service apparatus that is connected over the first network;
• transmitting the user request to a second terminal connected over the second network;
• receiving information associated with the second terminal from the second terminal;
• and
• transmitting information associated with the second terminal to the virtual smart home service apparatus,
• wherein the virtual smart home service apparatus is generated through a virtualization technology of a server, and the first network and the second network are different from each other.
