Reservation of spectrum resources in white spaces
View Patent ↗A white space entity reserves spectrum in white space from a reservation system. Consequently, the white space entity may utilize television bands that are unused at a specified time period and geo-location in order to support different services such as wireless audio transmission, networking, video surveillance, and video conferencing. The white space entity requests reservation of spectrum resources from the reservation system by sending a reservation request. The request includes request parameters that may include geo-location, model number or manufacture code number, priority of entity, reservation time period, and maximum power level. The reservation system consequently verifies the request from the priority of the white space entity and the availability of white space spectrum for the desired time period. The white space entity then extracts confirmation parameters from a reservation confirmation message and subsequently transmits on white spectrum in accordance with the parameters.
1. A method comprising:
sending a request, by a white space entity to a reservation computer system, said request seeking reservation of a white space spectrum resource during a requested time period, and said request indicating a requested geo-location;
receiving a reservation confirmation at the white space entity, the reservation confirmation indicative of a reserved white space spectrum resource, a reserved geo-location, and a reserved time period; and
transmitting, by the white space entity, on the reserved white space spectrum resource during the reserved time period.
2. The method of claim 1 , wherein the white space entity comprises a portable device able to transmit on the reserved white space spectrum resource.
3. The method of claim 1 , wherein the white space entity comprises an access point.
4. The method of claim 1 , further comprising:
establishing, by the white space entity, a communications connection with the reservation computer system.
5. The method of claim 1 , wherein:
the reserved geo-location contains at least a portion of the requested geo-location; and
the transmitting only occurs when the white space entity is located in the reserved geo-location.
6. The method of claim 1 , wherein:
the request is indicative of a requested power level;
the reservation confirmation is indicative of a reserved power level; and
the transmitting includes transmitting at a transmitted power level that does not exceed the reserved power level.
7. The method of claim 1 , wherein the sending and the transmitting utilize non-overlapping radio spectra.
8. The method of claim 1 , further comprising:
receiving an indication that the reserved white space spectrum resource is available after the reserved time period; and
continuing to transmit, by the white space entity and after the reserved time period, on the reserved white space spectrum resource.
9. The method of claim 2 , further comprising:
adjusting a transmitted power level, by the portable device based on a geo-location of the portable device.
10. An apparatus comprising:
at least one processor; and
at least one memory having stored thereon machine executable instructions, the at least one memory and the machine executable instructions configured to, with the at least one processor, cause the apparatus to:
send a request to a reservation computer system, said request seeking reservation of a white space spectrum resource during a requested time period, and said request indicating a requested geo-location;
receive a reservation confirmation, the reservation confirmation indicative of a reserved white space spectrum resource, a reserved geo-location, and a reserved time period; and
transmit on the reserved white space spectrum resource during the reserved time period.
11. The apparatus of claim 10 , wherein:
the reserved geo-location contains at least a portion of the requested geo-location; and
the at least one memory and the machine executable instructions are configured to, with the at least one processor, cause the apparatus to:
transmit only when the apparatus is located in the reserved geo-location.
12. The apparatus of claim 10 , wherein:
the request is indicative of a requested power level;
the reservation confirmation is indicative of a reserved power level; and
the at least one memory and stored instructions are further configured to, with the at least one processor, cause the apparatus to:
transmit at a transmitted power level that does not exceed the reserved power level.
13. One or more non-transitory computer readable media storing computer readable instructions that, when executed, cause an apparatus to:
send a request to a reservation computer system, said request seeking reservation of a white space spectrum resource during a requested time period, and said request indicating a requested geo-location;
receive a reservation confirmation, the reservation confirmation indicative of a reserved white space spectrum resource, a reserved geo-location, and a reserved time period; and
transmit on the reserved white space spectrum resource during the reserved time period.
14. A method comprising:
receiving a reservation request, by a reservation computer system from a white space entity, said reservation request seeking a reservation of a white space spectrum resource during a requested time period, and said reservation request indicating a requested geo-location;
verifying, by the reservation computer system, the reservation request;
updating a data structure in accordance with a reserved time period and a reserved white space spectrum resource; and
in response to the verifying, sending, by the reservation computer system, a reservation confirmation to the white space entity, the reservation confirmation indicative of the reserved white space spectrum resource, a reserved geo-location, and the reserved time period.
15. The method of claim 14 , wherein the verifying comprises:
determining whether the white space spectrum resource is consistent with a priority level of the white space entity.
16. The method of claim 14 , wherein the verifying comprises:
performing an interference analysis using the requested geo-location and a maximum transmitted power level of the white space entity.
17. The method of claim 14 , wherein the verifying comprises:
confirming whether the request is in accordance with regulatory rules.
18. The method of claim 14 , wherein the reservation confirmation is indicative of an allowed power level and an allowed geo-location of the white space entity.
19. An apparatus comprising:
at least one processor; and
at least one memory having stored thereon machine executable instructions, the at least one memory and the machine executable instructions configured to, with the at least one processor, cause the apparatus to:
receive a reservation request from a white space entity, said reservation request seeking a reservation of a white space spectrum resource during a requested time period, and said reservation request indicating a requested geo-location;
verify the reservation request;
update a data structure in accordance with a reserved time period and a reserved white space spectrum resource; and
send a reservation confirmation to the white space entity, the reservation confirmation indicative of the reserved white space spectrum resource, a reserved geo-location, and the reserved time period.
20. The apparatus of claim 19 , wherein the at least one memory and the machine executable instructions are configured to, with the at least one processor, cause the apparatus to:
determine whether the requested white space spectrum resource is consistent with a priority level of the white space entity.
21. The apparatus of claim 19 , wherein the at least one memory and the machine executable instructions are configured to, with the at least one processor, cause the apparatus to:
perform an interference analysis using the requested geo-location and a maximum transmitted power level of the white space entity.
