White space database discovery
Methods and apparatus, including computer program products, are provided for white space database discovery. In one aspect there is provided a method. The method may include sending, by a user equipment, a request to a server including a white space database, wherein the server is located at a first address; and receiving, at the user equipment, a response to the request, the response including at least one of an identity of the server or a second address for accessing at least one of the server or another server including another white space database. Related apparatus, systems, methods, and articles are also described.
1. A method comprising:
sending, by a user equipment, a request to a server including a white space database, wherein the server is located at a first address, and wherein the request comprises an INIT REQ message, an AVAIL SPECTRUM REQ message, an AVAIL SPECTRUM BATCH REQ message, and/or a registration message; and
receiving, at the user equipment and from the server, a response to the request, the response including a white space database update indicating a second address for accessing the server, wherein the second address is representative of an address change and/or an address update of the first address, and wherein the response comprises an INIT RESP message, an AVAIL SPECTRUM RESP message, an AVAIL SPECTRUM BATCH RESP message, and/or a registration response message.
2. The method of claim 1 , wherein the response further includes a start time representative of when the server is not accessible to obtain an allocation of a white space frequency due to one of a permanent shutdown of the server or a temporary shutdown of the server.
3. The method of claim 1 , wherein the request includes a white space related information parameter.
4. The method of claim 1 , wherein the response further includes an indication of whether the first address is to be replaced with the second address.
5. The method of claim 1 , wherein the first address is a database uniform resource identifier.
6. The method of claim 1 , wherein the response includes a plurality of addresses for a plurality of white space databases.
7. The method of claim 1 , wherein the response further includes registration information associated with the second address in the response and/or authorization information associated with the second address in the response.
8. The method of claim 1 , wherein the server comprises a provisioning server and/or a regulatory server, wherein the provisioning server is maintained by a manufacturer of the user equipment to provide the response including addresses of white space databases available and authorized to allocate white space frequencies to the user equipment, and wherein the regulatory server is maintained by a regulator of white space frequencies in a regulatory domain covered by the user equipment.
9. An apparatus comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
send a request to a server including a white space database, wherein the server is located at a first address, and wherein the request comprises an INIT REQ message, an AVAIL SPECTRUM REQ message, an AVAIL SPECTRUM BATCH REQ message, and/or a registration message; and
receive, from the server, a response to the request, the response including a white space database update indicating a second address for accessing the server, wherein the second address is representative of an address change and/or an address update of the first address, and wherein the response comprises an INIT RESP message, an AVAIL SPECTRUM RESP message, an AVAIL SPECTRUM BATCH RESP message, and/or a registration response message.
10. The apparatus of claim 9 , wherein the response further includes a start time representative of when the server is not accessible to obtain an allocation of a white space frequency due to one of a permanent shutdown of the server or a temporary shutdown of the server.
11. The apparatus of claim 9 , wherein the request includes a white space related information parameter.
12. The apparatus of claim 9 , wherein the response further includes an indication of whether the first address is to be replaced with the second address.
13. The apparatus of claim 9 , wherein the first address is a database uniform resource identifier.
14. The apparatus of claim 9 , wherein the response includes a plurality of addresses for a plurality of white space databases.
15. The apparatus of claim 9 , wherein the response further includes registration information associated with the second address in the response and/or authorization information associated with the second address in the response.
16. The apparatus of claim 9 , wherein the server comprises a provisioning server and/or a regulatory server, wherein the provisioning server is maintained by a manufacturer of the apparatus to provide the response including addresses of white space databases available and authorized to allocate white space frequencies to the apparatus, and wherein the regulatory server is maintained by a regulator of white space frequencies in a regulatory domain covered by the apparatus.
