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 gateway, comprising:

at least one processor; and

at least one memory including computer program code;

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least;

receive, from a wireless tag, a wireless beacon signal;

determine, based on the wireless beacon signal, whether the wireless gateway is a trusted wireless gateway for the wireless tag; and

initiate, based on a determination that the wireless gateway is a trusted wireless gateway for the wireless tag, establishment of a connection between the wireless tag and the wireless gateway.

2. The wireless gateway of claim 1, wherein, to determine whether the wireless gateway is a trusted wireless gateway for the wireless tag, the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

determine, based on the wireless beacon signal, an identity of the wireless tag;

send, toward a location server, an indication of the identity of the wireless tag; and

determine, based on a response from the location server, whether the wireless gateway is a trusted wireless gateway for the wireless tag.

3. The wireless gateway of claim 2, wherein the identity of the wireless tag is determined based on at least one of analysis of one or more wireless characteristics of the wireless beacon signal or information included within the wireless beacon signal.

4. The wireless gateway of claim 1, wherein, to determine whether the wireless gateway is a trusted wireless gateway for the wireless tag, the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

determine, based on the wireless beacon signal, an identity of the wireless tag; and

determine, based the identity of the wireless tag and based on information maintained by the wireless gateway that is indicative of a set of wireless tags for which the wireless gateway is a trusted wireless gateway, whether the wireless gateway is a trusted wireless gateway for the wireless tag.

5. The wireless gateway of claim 4, wherein the identity of the wireless tag is determined based on at least one of analysis of one or more wireless characteristics of the wireless beacon signal or information included within the wireless beacon signal.

6. The wireless gateway of claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

receive, from the wireless tag via the connection between the wireless tag and the wireless gateway, information of the wireless tag; and

send, toward a location server, at least a portion of the information of the wireless tag.

7. The wireless gateway of claim 6, wherein the information of the wireless tag includes at least one of an identifier of the wireless tag, location tracking information of the wireless tag, or data collected by the wireless tag.

8. The wireless gateway of claim 6, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

determine location tracking information for the wireless tag; and

send, toward the location server, the location tracking information for the wireless tag.

9. The wireless gateway of claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

determine location tracking information for the wireless tag; and

send, toward the location server, the location tracking information for the wireless tag.

10. The wireless gateway of claim 9, wherein the location tracking information for the wireless tag comprises at least one of an identifier of the wireless gateway, a location of the wireless gateway, or an indication that the wireless tag is within a vicinity of the wireless gateway.

11. The wireless gateway of claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

receive, from the wireless tag via the connection between the wireless tag and the wireless gateway, location tracking information determined by the wireless tag;

generate, based on receipt of the location tracking information determined by the wireless tag, location tracking information determined by the wireless gateway; and

send, toward the location server, the location tracking information determined by the wireless gateway.

12. The wireless gateway of claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

receive, from the wireless tag via the connection between the wireless tag and the wireless gateway, location tracking information determined by the wireless tag;

determine, based on the location tracking information determined by the wireless tag, a location of the wireless tag; and

send, toward the location server, an indication that the wireless tag is within a vicinity of the wireless gateway.

13. The wireless gateway of claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

transmit, via the connection between the wireless tag and the wireless gateway, heartbeat signals;

or

monitor for receipt of heartbeat signals via the connection between the wireless tag and the wireless gateway.

14. The wireless gateway of claim 1, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the wireless gateway to at least:

initiate, based on a determination that a heartbeat signal has not been received via the connection between the wireless tag and the wireless gateway for a threshold length of time, termination of the connection between the wireless tag and the wireless gateway.

15. A method, comprising:

receiving, by a wireless gateway from a wireless tag, a wireless beacon signal;

determining, by the wireless gateway based on the wireless beacon signal, whether the wireless gateway is a trusted wireless gateway for the wireless tag; and

initiating, by the wireless gateway based on a determination that the wireless gateway is a trusted wireless gateway for the wireless tag, establishment of a connection between the wireless tag and the wireless gateway.
