System and method for centralized station management
First Claim
1. A wireless network adapted with a plurality of access points and a station, comprising:
- an interconnect; and
a wireless network switch coupled to the interconnect for communications with the plurality of access points, the wireless network switch to receive a DEAUTHENTICATION message sent by one of the plurality of access points in a coverage area of the station and to block communications between the plurality of access points and the station in response to determining that the DEAUTHENTICATION message is invalid.

Abstract
In one embodiment of the invention, a wireless network is adapted with a wireless network switch in communication with a plurality of access points, which are in communication with one or more stations. Coupled to the access points over an interconnect, the wireless network switch is adapted to receive a DEAUTHENTICATION message sent by one of the plurality of access points in the same coverage area of the station so as to detect the DEAUTHENTICATION message and to block communications between the plurality of access points and the station in response to determining that the DEAUTHENTICATION message is invalid.

7. A method for selectively associating with a station transmitting a first PROBE REQUEST message followed by a second PROBE REQUEST message under control of a wireless network switch, comprising:
-
receiving a received signal strength indicator (RSSI) value corresponding to signal strength of the first PROBE REQUEST message detected by each access point;
receiving a message identifying that the second PROBE REQUEST message has been detected; and
responding only to the second PROBE REQUEST message on behalf of an access point selected to associate with the station using at least the RSSI value. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method comprising:
-
setting a plurality of received signal strength indicator (RSSI) thresholds including a first RSSI threshold and a second RSSI threshold having a value lower than the first RSSI threshold;
computing a RSSI value for a management message by a plurality of access points detecting the management message, the management message originating from a station; and
placing an address of the station into a list identifying stations located in a potential coverage hole if none of the plurality of access points computes a RSSI value of the management message above the second RSSI threshold. - View Dependent Claims (14, 15, 16, 17)

18. A method comprising:
-
receiving a PROBE REQUEST message on different channels by a plurality of access points, the PROBE REQUEST message being sent from a station;
forwarding the PROBE REQUEST message from each of the plurality of access points, each PROBE REQUEST message includes a channel number and media access control (MAC) address of an access point forwarding the PROBE REQUEST message;
creating a list including the MAC address of each of the plurality of access points and the corresponding channel number; and
providing the list to the station originally initiating the PROBE REQUEST message at completion of an association phase between the station and one of the plurality of access points. - View Dependent Claims (19)
