Abstract

A smart home system using a portable device in which a gateway function is installed in the portable device to provide a smart home service using a multiplex gateway, and a control method thereof is provided. The smart home system includes one or more portable devices and one or more home appliances located in a home, each of the one or more portable devices and one or more home appliances having a gateway, a home network to interconnect the one or more portable devices and the one or more home appliances, and a master device selected from among the one or more portable devices or the one or more home appliances, the master device activating the gateway thereof to connect the home network with an external communication network, wherein the master device transfers a home appliance control command to a corresponding one of the one or more home appliances.

Claims

1. A home appliance, which is a device, comprising:

a gateway;

at least one memory storing instructions; and

at least one processor that executes the instructions so that the home appliance;

connects to a home network,

while connected to the home network, communicates, through the home network, with another device that is connected to the home network and that includes a gateway, to determine whether the home appliance is to be a master device of the home appliance and the another device, based on device information of the home appliance and device information of the another device,

activate the gateway of the home appliance in response to it being determined that the home appliance is to be the master device, so that the gateway of the home appliance thereby connects the home network with an external communication network, and

while the gateway of the home appliance is activated and thereby connects the home network with the external communication network,

causes the activated gateway to be operable to receive a control command for the another device from the external communication network, and transfer the received control command through the home network to the another device.

2. The home appliance according to claim 1, wherein the device information comprises Internet protocol (IP) address information.

3. The home appliance according to claim 1, wherein the another device is a home appliance.

4. A home appliance, which is a device, comprising:

a gateway;

at least one memory storing instructions; and

at least one processor that executes the instructions so that the home appliance;

connects to a home network,

while connected to the home network, communicates, through the home network, with other devices, each equipped with a gateway, that are connected to the home network, to determine whether the home appliance is to be a master device of the home appliance and the other devices, based on device information of the home appliance and device information of the other devices,

activates the gateway of the home appliance in response to it being determined that the home appliance is to be the master device, so that the gateway of the home appliance thereby connects the home network with an external communication network, and

while the gateway of the home appliance is activated and thereby connects the home network with the external communication network,

for each respective device of the other devices, causes the activated gateway to be operable to receive a control command for the respective device from the external communication network, and transfer the received control command through the home network to the respective device.

5. The home appliance according to claim 4, wherein the at least one processor periodically transfers a check alive message to the other devices connected to the home network in response to it being determined that the home appliance is to be the master device.

6. The home appliance according to claim 5, wherein the at least one processor deactivates the gateway of the home appliance in response to it being determined that one of the other devices connected to the home network is to be the master device, and when no check alive message is received by one of the other devices, activates the gateway of the home appliance.

7. The home appliance according to claim 4, wherein the at least one processor deactivates the gateway of the home appliance so that a portable device is to be the master device, in response to the portable device being connected to the home network.

8. The home appliance according to claim 4, wherein the device information comprises Internet protocol (IP) address information.

9. The home appliance according to claim 4, wherein the other devices include at least one home appliance.

10. A portable device comprising:

a gateway;

at least one memory storing instructions; and

at least one processor that executes the instructions so that the portable device;

connects to a home network,

while connected to the home network, communicates, through the home network, with other devices, each equipped with a gateway, that are connected to the home network, to determine whether the portable device is to be a master device of the portable device and the other devices, based on device information of the portable device and device information of the other devices,

activates the gateway of the portable device in response to it being determined that the portable device is to be the master device, so that the gateway of the portable device thereby connects the home network with an external communication network, and

while the gateway of the portable device is activated and thereby connects the home network with the external communication network,

for each respective device of the other devices, causes the activated gateway to be operable to receive a control command for the respective device from the external communication network, and transfer the received control command through the home network to the respective device;

wherein the other devices include at least one home appliance.

11. The portable device according to claim 10, wherein the device information comprises Internet protocol (IP) address information.

12. The portable device according to claim 10, wherein the portable device is a mobile phone.

13. The portable device according to claim 10, wherein the at least one processor periodically transfers a check alive message to the other devices connected to the home network in response to it being determined that the portable device is to be the master device.

14. The portable device according to claim 13, wherein the at least one processor deactivates the gateway of the portable device in response to it being determined that one of the other devices connected to the home network is to be the master device, and when no check alive message is received by one of the other devices, activates the gateway of the portable device.

15. The portable device according to claim 10, wherein the at least one processor selects one of the portable device and another portable device connected to the home network as a new master device in response to the another portable device being connected to the home network.

16. The portable device according to claim 15, wherein the at least one processor selects the new master device based on the history information of the another portable device and history information of the portable device.

17. The portable device according to claim 15, wherein the at least one processor deactivates the gateway of the portable device in response to it being determined that the another portable device connected to the home network is to be the new master device.

18. The portable device according to claim 10, wherein the at least one processor activates the gateway of the portable device so that another portable device is to be the master device, in response to the another portable device being connected to the home network.
