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 has fields formatted according to the EPCglobal standards and certain bits within one of the fields 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 from the Tag to a network device referred to as a personality class appliance which receives the IP multicast packet. Thus, the Reader is an IP multicast sender and the appliance is an IP multicast receiver. 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 via a unicast message. Once the Reader receives the configuration data, it provisions itself, becomes connected to the RFID network, and is ready for operation. RFID Readers and other devices can be provisioned automatically for a specific role when turned on, without requiring any manual configuration or data entry.

Claims

1. A method of provisioning a radio frequency identification (“

RFID”

) device, the method comprising;

reading an affixed RFID Tag associated with the RFID device;

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

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.

2. A method as recited in claim 1 wherein receiving a second data packet further comprises receiving the second data packet via unicast IP.

3. A method as recited in claim 1 wherein receiving a second data packet further comprises receiving the second data packet via IP multicasting.

4. A method as recited in claim 1 further comprising transmitting an acknowledgment message upon completion of provisioning.

5. A method as recited in claim 1 further comprising identifying the RFID tag as an Electronic Product Code (“

EPC”

) identity tag.

6. A method as recited in claim 1 further comprising 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.

7. The method as recited in claim 1, further comprising:

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.

8. A method of provisioning a radio frequency identification (“

RFID”

) device, the method comprising;

receiving a first data packet via Internet Protocol (IP) multicast from the RFID device having a specific role performed by one of a plurality of classes of RFID devices;

reading 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;

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

transmitting 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. A method as recited in claim 8 wherein transmitting the configuration parameters to the RFID device further comprises transmitting via unicast IP.

10. A method as recited in claim 8 wherein transmitting the configuration parameters to the RFID device further comprises transmitting via IP multicast.

11. The method as recited in claim 8, wherein the value is a personality class value.

12. A radio frequency identification (“

RFID”

) Tag comprising;

a first field for identifying the RFID Tag as a certain type of Tag;

a second field for classifying an associated RFID device as one of a plurality of personality classes of RFID devices; and

a third field for storing a serial number that uniquely identifies the RFID Tag;

wherein the tag is affixed to the RFID device.

13. An RFID Tag as recited in claim 12 wherein the first field is a filter value field.

14. An RFID Tag as recited in claim 12 wherein a reserved binary encoding in the filter value field classifies the Tag as an Electronic Product Code (EPC) identity Tag.

15. An RFID Tag as recited in claim 12 wherein the Tag remains at one position in the RFID network.

16. An RFID Tag as recited in claim 12 wherein the Tag is affixed within a read field of the associated RFID device.

17. An RFID Tag as recited in claim 12 wherein the Tag is affixed to an antenna of the associated RFID device.

18. An RFID Tag as recited in claim 12 wherein the Tag is affixed within read fields of a plurality of associated RFID devices.

19. A radio frequency identification (“

RFID”

) network comprising;

at least one RFID device having a read field;

at least one Electronic Product Code (EPC) Tag associated with the at least one RFID device and within the read field of the device, wherein the at least one EPC Tag associated with the at least one RFID device includes a field indicating one of a plurality of personality classes of RFID devices; and

a network component having access to configuration parameters for the at least one RFID device such that a different set of configuration parameters is stored in association with each one of the plurality of personality classes of RFID devices, wherein connectivity between the RFID device and the network device is Internet Protocol (IP) multicast enabled.

20. An RFID network as recited in claim 19 wherein the RFID device is an IP multicast receiver.

21. An RFID network as recited in claim 20 wherein the network component is an IP multicast sender.

22. A radio frequency identification (RFID) device comprising:

an Electronic Product Code (EPC) Tag storing a first value indicating that the EPC Tag is an Identity Tag and a second value indicating a personality class of the device, the personality class of the device being one of a plurality of personality classes; and

a destination Internet Protocol (IP) multicast address of an external source from which configuration parameters for the personality class of the device are to be obtained.

23. A personality class appliance comprising:

a first storage area storing a plurality of personality class values, each of the plurality of personality class values identifying a different one of a plurality of personality classes;

a second storage area storing configuration parameters for configuring readers such that each of the readers is configured according to one of the plurality of personality classes, wherein the second storage area stores a different set of configuration parameters for each of the plurality of personality class values; and

a third storage area storing pairings of Electronic Product Code (“

EPC”

) Identity Tag serial number and one of the plurality of personality class values.
