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 located in premises in a wireless network which is constructed in the premises, the method comprising:

receiving a light signal including network identification information of the wireless network constructed in the premises from at least one illumination device configured to illuminate the premises; and

registering the wireless device in the wireless network constructed in the premises, by using the network identification information included in the received light signal.

2. The method of claim 1, further comprising scanning at least one wireless network which is usable at a current location of the wireless device,

wherein the registering of the wireless device in the wireless network comprises registering the wireless device in a wireless network, which corresponds to network identification information included in the received light signal, from among the scanned wireless networks.

3. The method of claim 1, wherein the received light signal includes location information of the illumination device transmitting the light signal, and

wherein if the registering of the wireless device in the wireless network is completed, the wireless device transmits the location information included in the light signal to the wireless network.

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 installed in the premises and,

according to the request for a light signal, receiving the light signal transmitted from the illumination device.

5. A wireless device to be registered in a wireless network which is constructed in premises, the wireless device comprising:

a light receiving unit to receive a light signal transmitted from at least one illumination device configured to illuminate the premises;

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

a wireless communication unit to register the wireless device in the wireless network constructed in the premises, by using the network identification information obtained by the light signal interpretation unit.

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 registers the wireless device in a wireless network, which corresponds to the network identification information obtained from the light signal interpretation unit, from among wireless networks scanned by the network scanning unit.

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 in which the wireless device is registered.

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