Abstract

Methods and devices are provided for identifying, locating and provisioning individual RFID devices in a network with “personalities” that are appropriate for the roles of the RFID devices. According to some implementations of the invention, a combination of EPC code information and existing networking standards form the basis of identifying and provisioning methods. For example, MAC address information and EPC information can be combined to identify a particular device and its location in a network. For implementations using the Dynamic Host Configuration Protocol (“DHCP”), DHCP Options may be used to pass provisioning information. Some implementations employ Domain Name Service (“DNS”) and dynamic DNS (“DDNS”) to allow easy identification of RFID devices.

Claims

1. A method, comprising:

receiving a message on a network; and

automatically determining a device identity according to a media access control (“

MAC”

) address and a product code included in the message.

2. The method of claim 1, wherein the message comprises a provisioning request.

3. The method of claim 1, further comprising automatically determining a device location according to location information included in the message.

4. The method of claim 1, wherein the product code comprises an electronic product code (“

EPC”

).

5. The method of claim 1, wherein the device is configured to capture temperature information.

6. The method of claim 1, wherein the device is configured to capture information regarding environmental changes.

7. The method of claim 1, wherein the device is configured to capture information regarding stresses.

8. The method of claim 1, wherein the device is configured to capture information regarding accelerations.

9. The method of claim 1, wherein the device is configured to capture information regarding vibrations.

10. The method of claim 1, further comprising automatically providing the device with a functionality corresponding with an identity of the device.

11. The method of claim 2, further comprising automatically providing the device with a functionality corresponding with an identity of the device.

12. The method of claim 3, further comprising automatically providing the device with a functionality corresponding with a device location.

13. The method of claim 11, further comprising providing configuration information to the device according to provisioning information that has previously been established for the device identity.

14. A method, comprising:

forming a DHCPDISCOVER request that includes an electronic product code (“

EPC”

) of a device;

sending the DHCPDISCOVER request to a Dynamic Host Configuration Protocol (“

DHCP”

) server; and

receiving provisioning information from the DHCP server that corresponds with the EPC, the provisioning information enabling a functionality that corresponds with a device identity.

15. The method of claim 14, wherein the forming step comprises forming a DHCPDISCOVER request that includes device location information.

16. The method of claim 15, wherein the provisioning information enables a functionality that corresponds with a device location.

17. The method of claim 15, wherein the device includes the EPC in the DHCPDISCOVER request during a first part of the forming step and wherein a relay agent includes the location information in the DHCPDISCOVER request during a second part of the forming step.

18. An apparatus, comprising:

at least one network interface configured for receiving a provisioning request from a device via a network; and

a processor configured to do the following;

ascertain a device identity according to a media access control (“

MAC”

) address and an electronic product code (“

EPC”

) included in the provisioning request;

determine a device functionality that corresponds with the device identity; and

provide, via a network interface, provisioning information corresponding to the determined device functionality.

19. The apparatus of claim 18, wherein the provisioning request further comprises location information and wherein the processor is further configured to do the following:

ascertain a device location; and

determine the device functionality according to the device location.

20. The apparatus of claim 18, wherein the device is configured to capture information regarding at least one of temperature, stresses, accelerations and vibrations.
