Abstract

A capability for localization of a wireless tag based on wireless gateway association information uses a wireless tag supporting multiple states and wireless gateway association information associated with the wireless tag to control localization of the wireless tag. The wireless tag may support an unconnected state in which the wireless tag communicates location tracking information using a wireless beacon signal which may be detected by various wireless gateways and a connected state in which the wireless tag communicates location tracking information via one or more connections with one or more wireless gateways. The wireless gateway association information may include wireless gateway lists (e.g., whitelists, blacklists, or the like), association rules, notification rules, or the like. The wireless gateway association information may be used to control transitions of the wireless tag between the unconnected state and the connected state, to control notifications for the wireless tag, or the like.

Claims

1. A wireless tag, comprising:

a wireless communication module configured to support wireless communications of the wireless tag, the wireless tag configured to support an unconnected state in which the wireless tag communicates location tracking information via transmission of wireless beacon signals and a connected state in which the wireless tag communicates location tracking information via a connection between the wireless tag and a wireless gateway; and

a controller configured to control a transition of the wireless tag from the unconnected state to the connected state based on an indication that the wireless gateway is a trusted wireless gateway for the wireless tag.

2. The wireless tag of claim 1, wherein the indication that the wireless gateway is a trusted wireless gateway for the wireless tag comprises an indication of establishment of the connection between the wireless tag and the wireless gateway.

3. The wireless tag of claim 1, wherein the controller is configured to determine that the wireless gateway is a trusted wireless gateway for the wireless tag based on wireless gateway association information maintained on the wireless tag.

4. The wireless tag of claim 3, wherein the wireless gateway association information maintained on the wireless tag comprises a wireless gateway whitelist for the wireless tag, wherein, to determine that the wireless gateway is a trusted wireless gateway for the wireless tag, the controller is configured to:

determine an identity of the wireless gateway based on a wireless signal received from the wireless gateway; and

determine, based the identity of the wireless gateway, whether the wireless gateway is on the wireless gateway whitelist for the wireless tag.

5. The wireless tag of claim 3, wherein the wireless tag is configured to receive the wireless gateway association information from a location server via at least one wireless gateway.

6. The wireless tag of claim 1, wherein the indication that the wireless gateway is a trusted wireless gateway for the wireless tag is received from the wireless gateway.

7. The wireless tag of claim 1, wherein the controller is configured to:

control a transition of the wireless tag from the connected state back to the unconnected state based on an indication that the connection between the wireless tag and the wireless gateway has terminated.

8. A method, comprising:

supporting, by a wireless communication module of a wireless tag configured to support an unconnected state in which the wireless tag communicates location tracking information via transmission of wireless beacon signals and a connected state in which the wireless tag communicates location tracking information via a connection between the wireless tag and a wireless gateway, wireless communications of the wireless tag; and

controlling, by a controller of the wireless tag, a transition of the wireless tag from the unconnected state to the connected state based on an indication that the wireless gateway is a trusted wireless gateway for the wireless tag.

9. The method of claim 8, wherein the indication that the wireless gateway is a trusted wireless gateway for the wireless tag comprises an indication of establishment of the connection between the wireless tag and the wireless gateway.

10. The method of claim 8, further comprising:

determining that the wireless gateway is a trusted wireless gateway for the wireless tag based on wireless gateway association information maintained on the wireless tag.

11. The method of claim 10, wherein the wireless gateway association information maintained on the wireless tag comprises a wireless gateway whitelist for the wireless tag, wherein determining that the wireless gateway is a trusted wireless gateway for the wireless tag comprises:

determining an identity of the wireless gateway based on a wireless signal received from the wireless gateway; and

determining, based the identity of the wireless gateway, whether the wireless gateway is on the wireless gateway whitelist for the wireless tag.

12. The method of claim 10, wherein the wireless gateway association information is received from a location server via at least one wireless gateway.

13. The method of claim 8, wherein the indication that the wireless gateway is a trusted wireless gateway for the wireless tag is received from the wireless gateway.

14. The method of claim 8, further comprising:

controlling, by the controller of the wireless tag, a transition of the wireless tag from the connected state back to the unconnected state based on an indication that the connection between the wireless tag and the wireless gateway has terminated.

15. A non-transitory computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to perform a method, the method comprising:

supporting, by a wireless communication module of a wireless tag configured to support an unconnected state in which the wireless tag communicates location tracking information via transmission of wireless beacon signals and a connected state in which the wireless tag communicates location tracking information via a connection between the wireless tag and a wireless gateway, wireless communications of the wireless tag; and

controlling, by a controller of the wireless tag, a transition of the wireless tag from the unconnected state to the connected state based on an indication that the wireless gateway is a trusted wireless gateway for the wireless tag.

16. The non-transitory computer-readable storage medium of claim 15, wherein the indication that the wireless gateway is a trusted wireless gateway for the wireless tag comprises an indication of establishment of the connection between the wireless tag and the wireless gateway.

17. The non-transitory computer-readable storage medium of claim 15, the method further comprising:

determining that the wireless gateway is a trusted wireless gateway for the wireless tag based on wireless gateway association information maintained on the wireless tag.

18. The non-transitory computer-readable storage medium of claim 17, wherein the wireless gateway association information maintained on the wireless tag comprises a wireless gateway whitelist for the wireless tag, wherein determining that the wireless gateway is a trusted wireless gateway for the wireless tag comprises:

determining an identity of the wireless gateway based on a wireless signal received from the wireless gateway; and

determining, based the identity of the wireless gateway, whether the wireless gateway is on the wireless gateway whitelist for the wireless tag.

19. The non-transitory computer-readable storage medium of claim 17, wherein the wireless gateway association information is received from a location server via at least one wireless gateway.

20. The non-transitory computer-readable storage medium of claim 15, the method further comprising:

controlling, by the controller of the wireless tag, a transition of the wireless tag from the connected state back to the unconnected state based on an indication that the connection between the wireless tag and the wireless gateway has terminated.
