Abstract

Provided is a method for registering TVWS devices for coexistence of television white space (TVWS) devices in a television white space (TVWS), the method performed a server and comprising receiving a registration request message for registration or update registration of at least one TVWS device from at least one management device; performing the registration or update registration of at least one TVWS device; and in response to the registration request message, transmitting a registration response message to the at least one management device, wherein the registration response message includes at least one of an identifier field of an interface device connected to the at least one TVWS device, a status field indicating a result of the registration or the update registration, and a reason field indicating a reason why the registration or the update registration is failed if the registration or the update registration is failed.

Claims

1. A method for registering television white space (TVWS) devices for coexistence of TVWS devices in a TVWS, the method performed by a server and comprising:

receiving one or more registration request messages for registration or update registration of one or more TVWS devices from at least one management device;

performing the registration or update registration of one or more TVWS devices; and

in response to the one or more registration request messages, transmitting one or more registration response messages to the at least one management device,

wherein the transmitting one or more registration response messages to the at least one management device includes transmitting identical registration response messages to at least two management devices.

2. The method according to claim 1, wherein

the reason field is set to 1 if the number of TVWS devices which have currently registered to the server is same as the maximum number of TVWS devices which the server is capable to register, and

the reason field is set to 2 if information of the registration or the update registration is wrong.

3. The method according to claim 1, wherein each registration request message includes at least one of the maximum number of TVWS devices that can be controlled by a corresponding management device, a geo-location and coverage radius of the corresponding management device.

4. The method according to claim 1, wherein

if the registration or the update registration is successfully performed, the status field is set to success;

and

if the registration or the update registration is not successfully performed, the status field is set to failure.

5. The method according to claim 1, wherein if the registration or the update registration is successfully performed for at least one TVWS device among the one or more TVWS devices, the identifier field of the registration response message for the at least one TVWS device further includes an identifier of an interface device connected to the at least one TVWS device.

6. The method according to claim 1, wherein if the registration or the update registration is not successfully performed for at least one TVWS device among the one or more TVWS devices, the identifier field of the registration response message for the at least one TVWS device further includes an identifier of an interface device connected to the at least one TVWS device.

7. The method according to claim 1, wherein

the identical registration response messages are transmitted to management devices which have transmitted the registration request messages for the TVWS devices of which the registration or the update registration is success.

8. The method according to claim 1, wherein

the identical registration response messages are transmitted to management devices which have transmitted the registration request messages for the TVWS devices of which the registration or the update registration is failed due to same reason.

9. A method for registering television white space (TVWS) devices for coexistence of TVWS devices in a TVWS, the method performed by a first management device and comprising:

receiving a first registration request message for registration or update registration of a TVWS device from at least one interface device connected to the TVWS device;

transmitting a second registration request message for the registration or the update registration to a server based on the first registration request message, the registration or the update registration being performed by the server in response to the second registration request message;

receiving a first registration response message from the server in response to the second registration request message;

performing the registration or the update registration based on the first registration response message, and

transmitting a second registration response message to the at least one interface device,

wherein the first registration response message is identical to a second registration response message which is transmitted from the server to a second management device.

10. The method according to claim 9, wherein

the reason field is set to 1 if the number of TVWS devices which have currently registered to the server is same as the maximum number of TVWS devices which the server is capable to register, and

the reason field is set to 2 if information of the registration or the update registration is wrong.

11. The method according to claim 9, wherein the first registration request message includes an identifier (ID) or a serial number (SN) of the TVWS device.

12. The method according to claim 9, wherein the second registration request message includes at least one of the maximum number of TVWS devices that can be controlled by the first management device, a geo-location and coverage radius of the first management device.

13. The method according to claim 9, wherein

if the registration or the update registration is successfully performed by the server, the status field of the first registration response message is set to success;

and

if the registration or the update registration is not successfully performed, the status field of the first registration response message is set to failure.

14. The method according to claim 9, wherein if the registration or the update registration of the TVWS device is successfully performed by the server, the identifier field of the first registration response message further includes an identifier of an interface device connected to the TVWS device.

15. The method according to claim 9, wherein if the registration or the update registration of the TVWS device is not successfully performed by the server, the identifier field of the first registration response message further includes an identifier of an interface device connected to the TVWS device.

16. The method according to claim 9, wherein if the number of TVWS devices which have currently registered to the first management device is same as the maximum number of TVWS devices that can be controlled by the first management device, the second registration request messages is not transmitted to the server.
