Abstract

A smart home service which is capable of providing an environment in which calling a control command for a device is available via a user terminal protocol to control between the device and a user terminal based on different type of protocol and a control method for the same. The smart home service server connecting at least one device operated based on a first protocol to at least one user terminal operated based on a second protocol, includes an application programming interface (API) controller configured to allow a control command for the at least one device to be called via the second protocol of the at least one user terminal; a filter configured to convert the called control command according to the first protocol; and a control command transmitter configured to transmit the control command converted according to the first protocol, to the at least one device.

First claim

The invention claimed is:

1. A server operable to connect a home appliance operated based on a first protocol to a mobile terminal operated based on a second protocol, the server comprising:
an application programming interface (API) controller configured to provide an API for controlling the home appliance to the mobile terminal and receive a call command based on the second protocol from the mobile terminal;
a filter configured to receive the call command from the API controller and convert the call command to a control command of the home appliance, based on the first protocol, corresponding to the call command;
a transmitter configured to transmit the control command to the home appliance;
a device interlock interface connected to the home appliance;
an event receiver configured to receive state information of the home appliance based on the first protocol via the device interlock interface;
an event processor configured to provide the state information to the filter and an storage of the server; and
an event transmitter configured to transmit filtered state information of the home appliance, the filtered state information being converted to the second protocol by the filter,
wherein the call command comprises:
authentication information about the second protocol comprising a channel key,
user authentication information comprising a user ID, an application ID and an access token, and
device information comprising a device ID of the home appliance.

2. A control method for a server operable to connect a home appliance operated based on a first protocol to a mobile terminal operated based on a second protocol, the control method comprising:
providing an application programming interface (API) configured to receive a control command of the first protocol in the second protocol, to the mobile terminal;
obtaining, from the mobile terminal operating based on the second protocol, a control command for the home appliance, by the API controller of the server;
filtering, by a filter of the server, state information of the home appliance;
converting the control command according to the first protocol by the filter of the server based on the filtered state information;
transmitting the control command converted according to the first protocol, to the home appliance, by a control command transmitter of the server;
receiving the state information of the home appliance, in an event receiver of the server;
storing the state information in a storage of the server;
filtering, by the filter of the server, the state information of the home appliance based on authentication information about the second protocol and user authentication information in the control command; and
transmitting the stored state information to the mobile terminal, in an event transmitter of the server, in response to the obtaining the control command,
wherein the control command comprises:
protocol information about the second protocol operated by the mobile terminal, user information for authenticating a user of the mobile terminal, and
device information corresponding to the home appliance, and wherein the home appliance to be transmitted the control command is determined by the API controller using the device information.

3. The control method of claim 2 , wherein the mobile terminal to be transmitted the stored state information is determined based on the user information by the API controller.
