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 a light signal from an illumination device;

registering the wireless device in the wireless network, by using an information included in the received light signal;

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 the wireless network from among the scanned wireless networks.

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

receiving a light signal from an illumination device; and

registering the wireless device in the wireless network, by using an information included in the received light signal,

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.

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

receiving a light signal from an illumination device; and

registering the wireless device in the wireless network, by using an information included in the received light signal,

wherein the receiving of the light signal comprises

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

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

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

a light receiving unit configured to receive a light signal transmitted from an illumination device;

a light signal interpretation unit configured to obtain an information necessary for registering the wireless device in the wireless network by interpreting the received light signal;

a wireless communication unit to register the wireless device in the wireless network, by using the information obtained by the light signal interpretation unit; and

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 the wireless network from among wireless networks scanned by the network scanning unit.

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

a light receiving unit configured to receive a light signal transmitted from an illumination device; and

a light signal interpretation unit configured to obtain an information necessary for registering the wireless device in the wireless network by interpreting the received light signal;

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

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.

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

a light receiving unit configured to receive a light signal transmitted from an illumination device;

a light signal interpretation unit configured to obtain an information necessary for registering the wireless device in the wireless network by interpreting the received light signal; and

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

wherein the wireless communication unit requests a light signal to at least one illumination device.

7. An illumination device, the illumination device comprising:

a light generation unit to generate light; and

a control unit to adjust brightness of the light by controlling the generation of light by the light generation unit,

wherein the control unit controls an ON and OFF status of the light by using a pattern which indicates an information necessary for registering a wireless device to a wireless network, and

wherein ON and OFF frequencies of the light are equal to or higher than a blinking frequency that may not be perceived by a user.

8. An illumination device, the illumination device comprising:

a light generation unit to generate light;

a control unit to adjust brightness of the light by controlling the generation of light by the light generation unit, the control unit being configured to control an ON and OFF status of the light by using a pattern which indicates an information necessary for registering a wireless device to a wireless network; and

a communication unit to receive network identification information of the wireless network from outside.

9. A wireless network system, the wireless network system comprising:

an illumination device, to transmit a light signal including an information necessary for registering a wireless device to a wireless network;

a gateway to receive a request for registration from a wireless device which has received the light signal; and

a server to allow registration of the wireless device according to the request for registration,

wherein the light signal further includes location information of the illumination device that has transmitted the light signal, and

wherein the server receives location information of the illumination device from the wireless device which is allowed to be registered, and stores the received location information as location information of the wireless device.

10. A wireless network system, the wireless network system comprising:

an illumination device, to transmit a light signal including an information necessary for registering a wireless device to a wireless network;

a gateway to receive a request for registration from a wireless device which has received the light signal; and

a server to allow registration of the wireless device according to the request for registration,

wherein the server transmits network identification information of the wireless network to at least one illumination device.

11. A wireless network system, the wireless network system comprising:

an illumination device, to transmit a light signal including an information necessary for registering a wireless device to a wireless network;

a gateway to receive a request for registration from a wireless device which has received the light signal; and

a server to allow registration of the wireless device according to the request for registration,

wherein, if the wireless device requests a light signal, the illumination device may transmit a light signal.
