Abstract

Methods and systems for automatic provisioning of RFID devices in an RFID network are described. A device, such as a Reader, has within its read field a special EPC Identity (ID) Tag that is specifically encoded for that Reader. When the Reader boots up, it reads the special ID Tag. The Tag indicates that the Tag is an EPC ID Tag and the data contained in the Tag will be used to provision the Reader. The Reader transmits an IP multicast packet containing data to a personality class appliance. Upon receiving the packet, the appliance retrieves configuration parameters for the Reader. These parameters collectively make up a personality class for the Reader. The personality data are transmitted back to the Reader. Once the Reader receives the configuration data, it provisions itself, becomes connected to the RFID network.

Claims

1. An apparatus, comprising:

a processor; and

a memory, at least one of the processor or the memory being configured to;

read an affixed RFID Tag associated with a radio frequency identification (“

RFID”

) device;

transmit a first data packet via Internet Protocol (IP) multicasting containing data stored on the affixed RFID Tag, the first data packet indicating one of a plurality of personality classes of RFID devices, the one of the plurality of personality classes of RFID devices being a personality class in which the RFID device is classified; and

receive a second data packet containing configuration parameters that correspond to the one of a plurality of personality classes of RFID devices, wherein the configuration parameters enable automatic provisioning of the RFID device for a specific function performed by the RFID devices in the one of the plurality of personality classes.

2. The apparatus as recited in claim 1, at least one of the processor or the memory being further configured to:

automatically provision the RFID device for a specific function performed by the RFID devices in the one of the plurality of personality classes using the configuration parameters.

3. The apparatus as recited in claim 1 wherein the second data packet is received via unicast IP.

4. The apparatus as recited in claim 1 wherein the second data packet is received via IP multicasting.

5. The apparatus as recited in claim 1, at least one of the processor or the memory being further configured to transmit an acknowledgment message upon completion of provisioning.

6. The apparatus as recited in claim 1, at least one of the processor or the memory being further configured to identify the RFID tag as an Electronic Product Code (“

EPC”

) identity tag.

7. The apparatus as recited in claim 1, at least one of the processor or the memory being further configured to create a first data packet from data stored on the affixed RFID tag such that the first data packet identifies the one of the plurality of personality classes of RFID devices.

8. An apparatus, comprising:

a processor; and

a memory, at least one of the processor or the memory being configured to;

receive a first data packet via Internet Protocol (IP) multicast from a radio frequency identification (“

RFID”

) device having a specific role performed by one of a plurality of classes of RFID devices;

read a value in the first data packet, the value indicating the one of the plurality of classes of RFID devices to which the RFID device belongs;

retrieve configuration parameters for the one of a plurality of classes of RFID devices based on the value in the first data packet; and

transmit the configuration parameters to the RFID device, wherein the configuration parameters enable automatic provisioning of the RFID device to perform for the specific role of the one of the plurality of classes of RFID devices.

9. The apparatus as recited in claim 8, wherein the value is a personality class value.

10. The apparatus as recited in claim 8, wherein the configuration parameters are transmitted to the RFID device via unicast IP.

11. The apparatus as recited in claim 8, wherein the configuration parameters are transmitted to the RFID device via IP multicast.

12. An apparatus, comprising:

means for reading an affixed RFID Tag associated with a radio frequency identification (“

RFID”

) device;

means for transmitting a first data packet via Internet Protocol (IP) multicasting containing data stored on the affixed RFID Tag, the first data packet indicating one of a plurality of personality classes of RFID devices, the one of the plurality of personality classes of RFID devices being a personality class in which the RFID device is classified; and

means for receiving a second data packet containing configuration parameters that correspond to the one of a plurality of personality classes of RFID devices, wherein the configuration parameters enable automatic provisioning of the RFID device for a specific function performed by the RFID devices in the one of the plurality of personality classes.

13. The apparatus as recited in claim 12, further comprising:

means for automatically provisioning the RFID device for a specific function performed by the RFID devices in the one of the plurality of personality classes using the configuration parameters.

14. The apparatus as recited in claim 12, wherein the second data packet is received via unicast IP.

15. The apparatus as recited in claim 12 wherein the second data packet is received via IP multicasting.

16. The apparatus as recited in claim 12, further comprising:

means for transmitting an acknowledgment message upon completion of provisioning.

17. The apparatus as recited in claim 12, further comprising:

means for identifying the RFID tag as an Electronic Product Code (“

EPC”

) identity tag.

18. The apparatus as recited in claim 12, further comprising:

means for creating a first data packet from data stored on the affixed RFID tag such that the first data packet identifies the one of the plurality of personality classes of RFID devices.
