Abstract

Methods and systems of a wireless access point (WAP) configured to support wireless communications on a wireless local area network (WLAN). In an example system, a WAP with a non-volatile memory storing network event rules that indicate conditional parameters for an action for a targeted device, includes an event detection circuit to gather and analyze wireless communications activity, and a rule initiation circuit to initiate an action for a target device indicated by a network event rule. In an example, the rule initiation circuit is to initiate an action for a target device indicated by a network event rule, where the conditional parameters are satisfied at least in part by the gathered wireless communications activity from the one or more wireless stations.

First claim

What is claimed is:

1. A method, comprising:
gathering wireless communications activity at a location of a wireless access point (WAP) of one or more wireless stations in proximity to the WAP;
analyzing the gathered wireless communications activity to track behavior of the one or more wireless stations in proximity to the WAP;
determining whether the gathered wireless communications activity corresponds to a conditional parameter for a network event rule, the conditional parameter related to a network event, wherein the network event rule indicates at least one tagged wireless station to monitor for the network event, wherein the network event includes an unknown device being detected in range of the WAP or the at least one tagged wireless station, the network event rule including an action, based on the conditional parameter, for a target device to undertake responsive to the unknown device being within range of the WAP, the target device operatively coupled to a wireless local area network (WLAN) of the WAP; and
in response to the conditional parameter for the network event rule being satisfied, initiating the action for the target device indicated by the network event rule,
wherein the network event rule is programmatically entered or is generated by the WAP based on the behavior of the one or more wireless stations in proximity to the WAP.

2. The method of claim 1 , wherein a particular conditional parameter for a security network event rule is satisfied at least in part by the gathered wireless communications activity including intercepting probe requests transmitted from the unknown device, and the security network event rule initiates a security action for a security target device.

3. The method of claim 1 , wherein analyzing the gathered wireless communications comprises maintaining a table of tags to identify wireless stations and track the behavior of each of the wireless stations.

4. The method of claim 1 ,
wherein analyzing the gathered wireless communications activity comprises determining usage patterns by tracking a specified wireless station in proximity to the WAP, and detecting one or more reactions of a specified target device that correspond to specified wireless station; and
determining a new network event rule for the specified wireless station with conditional parameters from the usage patterns to automatically initiate the reaction for the specified the target device based on future gathered wireless communications activity from the specified target device.

5. The method of claim 1 , wherein the wireless communications include activity independent of the one or more wireless stations authenticated with the WAP.

6. The method of claim 1 , wherein gathering the wireless communication activity comprises intercepting wireless communication activity of a wireless station that is unassociated with the WAP.

7. The method of claim 1 , wherein gathering the wireless communication activity is via at least one of channel scanning, deep packet inspection, and probe requests.

8. The method of claim 1 , wherein the conditional parameter for the network event rule includes a change in proximity of the one or more wireless stations relative to the WAP based on the gathered wireless communications activity.

9. The method of claim 1 , wherein the conditional parameter for the network event rule include a transition in communication status of the one or more wireless stations relative to the WAP based on gathered wireless communications activity.

10. The method of claim 1 , wherein the conditional parameter relates to at least one of: a proximity, a location, a received signal strength indication (RSSI), or an association status of the one or more wireless stations.

11. The method of claim 8 , wherein the change in proximity indicates whether the one or more wireless stations is moving towards or away from the WAP based on the gathered wireless communications activity.

12. The method of claim 2 , wherein the particular conditional parameter for the security network event rule is further satisfied at least in part by determining an administrator tagged wireless station is not in proximity to the WAP, and the security action for the security target device includes at least one of turning on a light, recording with a security camera, and notifying a remote security service.

13. The method of claim 3 , wherein a tag of a previously identified wireless station is used each time wireless communications activity of that identified wireless station is gathered in proximity to the WAP.

14. The method of claim 3 , further comprising assigning a new tag in the table of tags for wireless communications activity gathered from an unidentified wireless station.

15. The method of claim 3 , further comprising assigning a wildcard tag for wireless communications activity intercepted from an unidentified wireless station that is not authenticated by the WAP.

16. A method comprising
initiating an action of a targeted device based on wireless communications activity gathered at a location of a wireless access point (WAP), wherein the gathered wireless communications activity is of one or more wireless stations in proximity to the WAP, wherein the wireless communications includes activity independent of the one or more wireless stations relationship with the WAP;
wherein a network event rule indicates at least a network event, a specified wireless station having been assigned to monitor for the network event, and the action of the targeted device, wherein the network event rule is triggered by a conditional parameter being satisfied based on gathered wireless communications activity for the specified wireless station indicating an occurrence of the network event, wherein the network event includes an unknown device being detected in range of the WAP or the specified wireless station, the action of the targeted device being initiated responsive to the unknown device being within range of the WAP, and wherein the network event rule is programmatically entered or is generated by the WAP based on the activity of the one or more wireless stations in proximity to the WAP.

17. The method of claim 16 , wherein gathering the wireless communication activity is via at least one of channel scanning and deep packet inspection.

18. The method of claim 16 , further comprising determining a new network event rule for the specified wireless station to automatically initiate an observed action for a corresponding target device with conditional parameters based on usage patterns from gathered wireless communications activity from the specified wireless station.

19. A wireless access point (WAP) configured to support wireless communications on a wireless local area network (WLAN), and the WAP comprising:
a plurality of components coupled to one another to form transmit and receive paths for processing wireless communications;
a non-volatile memory storing network event rules wherein one or more network event rules indicate at least conditional parameters to initiate an action for a targeted device;
an event detection circuit to gather wireless communications activity at a location of a wireless access point (WAP) of one or more wireless stations in proximity to the WAP, and analyze the gathered wireless communications activity to track behavior of the one or more wireless stations in proximity to the WAP; and
a rule initiation circuit to initiate an action for a target device indicated by a network event rule, wherein the conditional parameters are satisfied at least in part
