Abstract

A method of registering a wireless device located in premises in a wireless network which is constructed in the premises. The method includes receiving a light signal, which includes network identification information of the wireless network constructed in the premises from at least one illumination device installed in the premises, and registering the wireless device in the wireless network constructed in the premises, by using the network identification information of the wireless network included in the received light signal.

Claims

1. A method of registering a wireless device in a wireless network, the method comprising:

receiving, by the wireless device, a light signal including network identification information of the wireless network from at least one illumination device;

transmitting, by the wireless device, a request for connecting to the wireless network, by using the network identification information included in the received light signal; and

receiving, by the wireless device, an address allocated to the wireless device from the wireless network.

2. The method of claim 1,

wherein the transmitting of the request comprises:

scanning at least one wireless network which is usable at a current location of the wireless device;

checking whether one of the at least one scanned wireless network corresponds to the network identification information; and

transmitting the request to the wireless network corresponding to the network identification information.

3. The method of claim 1, further comprising transmitting a location information of the illumination device to the wireless network,

wherein the light signal includes the location information of the illumination device transmitting the light signal.

4. The method of claim 1, wherein the receiving of the light signal comprises:

sending a request for a light signal to at least one illumination device and,

receiving the light signal transmitted from the illumination device.

5. A wireless device to be registered in a wireless network, the wireless device comprising:

a light receiving unit to receive a light signal transmitted from at least one illumination device;

a light signal interpretation unit to obtain network identification information of the wireless network by interpreting the received light signal; and

a wireless communication unit to transmit a request for connecting to the wireless network, by using the network identification information, and receive an address allocated to the wireless device from the wireless network.

6. The wireless device of claim 5, further comprising a network scanning unit to scan at least one wireless network which is usable at a current location of the wireless device,

wherein the wireless communication unit checks whether one of the at least one scanned wireless network corresponds to the network identification information, and transmits the request to the wireless network corresponding to the network identification information.

7. The wireless device of claim 5, wherein the light signal interpretation unit obtains location information of an illumination device which has transmitted the light signal, by interpreting the received light signal, and

wherein the wireless communication unit transmits location information of the illumination device to the wireless network.

8. The wireless device of claim 5, wherein the wireless communication unit requests a light signal to at least one illumination device.

9. A method of registering a wireless device in a network, the method comprising:

receiving, from an illumination device, a light signal comprising network identification information;

transmitting, to a gateway device, a request of a registration to a connectible network based on the network identification information; and

registering to the connectible network.

10. The method of claim 9, further comprising scanning for connectible networks based on the identification information.

11. The method of claim 9, wherein the light signal further comprises location information.

12. The method of claim 9, wherein the registering is performed based on an allocation of a network address.

13. The method of claim 9, further comprising transmitting, to the illumination device, a request for the light signal.
