ABSTRACT:
A method for associating a WSTA to a service set, wherein the service set is configurable at the AP. Each service set is an arbitrary grouping of one or more network service parameters, and is typically configured for either VLAN or proxy mobile IP host. When a wireless station desires to associate with an access point, the wireless station sends a message to the access point, the message containing a SSID. The access point then matches the SSID to a service set and associates the WSTA to either a home subnet or a VLAN based on the SSID. By locally configuring the service set, the default VLAN and home subnet for a WSTA may be different at each AP the WSTA encounters. A security server is configured with a list of allowed SSIDs for each wireless station to prevent unauthorized access to a VLAN or home subnet.
