Abstract

Embodiments of the present invention include systems and methods for providing Quality of service to RFID. In one embodiment the present invention includes a method of providing quality of service in an RFID network comprising storing RFID priority information corresponding to the RFID network, wherein the RFID network comprises one or more tags and one or more readers mapping the RFID priority information into priority information corresponding to a second network.

Claims

1. A method of providing quality of service in an RFID network comprising:

storing RFID priority information corresponding to said RFID network, wherein the RFID network comprises one or more tags and one or more readers; and

mapping the RFID priority information into priority information corresponding to a second network.

2. The method of claim 1 wherein the RFID priority information is stored on one or more tags.

3. The method of claim 1 wherein RFID priority information corresponding to one or more tags is stored on a reader.

4. The method of claim 1 wherein the RFID priority information comprises tag priority information and reader priority information.

5. The method of claim 1 wherein the RFID priority information corresponding to one or more tags is stored external to the tag.

6. The method of claim 5 wherein the RFID priority information corresponding to one or more tags is cached on an access point in the second network.

7. The method of claim 1 wherein the RFID priority information is stored on one or more readers.

8. The method of claim 7 wherein the RFID priority information is based on attributes of the RFID network.

9. The method of claim 8 wherein the attributes of the RFID network include the location of a reader, a time, or an application type.

10. The method of claim 1 wherein the second network is a wired local area network, a wireless local area network, or a cellular network.

11. The method of claim 1 wherein the mapping is specified by a mapping algorithm.

12. The method of claim 1 wherein the priority information for the second network is calculated based on the RFID priority information of the RFID network, the number of priority levels available on the RFID network, and the number of available priority levels on the second network.

13. The method of claim 1 wherein a reader modifies the RFID priority information stored on a tag.

14. The method of claim 13 wherein the reader updates RFID priority information stored on the reader corresponding to the tag.

15. The method of claim 13 wherein the reader transmits the modified RFID priority information on the tag to one or more other readers.

16. A method of providing quality of service in an RFID network comprising:

receiving an RFID event on an RFID reader;

associating first priority information with the RFID event; and

executing the RFID event on said RFID reader based on the first priority information.

17. The method of claim 16 further comprising:

associating second priority information with the RFID event on a network external to said RFID network;

sending the RFID event and second priority information to said RFID reader; and

executing the RFID event based on the first and second priority information.

18. The method of claim 16 wherein the first priority information is stored on the reader.

19. The method of claim 16 wherein the first priority information is stored external to the reader.

20. The method of claim 16 wherein the first priority information comprises tag priority information.

21. The method of claim 16 wherein the first priority information comprises reader priority information.

22. The method of claim 16 wherein the first priority information comprises tag and reader priority information.

23. A system including an RFID network comprising:

one or more RFID readers coupled to at least one second network over a communication channel;

a plurality of RFID tags coupled to at least one of the RFID readers; and

RFID priority information,

wherein the RFID reader prioritizes processing RFID information based on the RFID priority information.

24. The system of claim 23 wherein the RFID information comprises RFID events received from the second network, and wherein the RFID reader receives an RFID event, associates RFID priority information with the RFID event, and executes the RFID event on said RFID reader based on the RFID priority information.

25. The system of claim 23 wherein the reader maps the RFID priority information into priority information corresponding to the second network.

26. The system of claim 23 wherein the RFID priority information is stored on the reader.

27. The system of claim 23 wherein the RFID priority information comprises tag priority information.

28. The system of claim 23 wherein the RFID priority information comprises reader priority information.

29. The system of claim 23 wherein one or more of the RFID readers are multimode readers, and wherein at least one RFID reader transmits and receives information using a first communication channel based on first RFID priority information, and wherein the at least one RFID reader transmits and receives information using a second communication channel based on second RFID priority information having a higher priority than the first RFID priority information.

30. The system of claim 29 wherein the first communication channel is a communication channel between the at least one RFID reader and another RFID reader, and the second communication channel is a communication channel between the at least one RFID reader and the second network.
