First Claim
Patent Images
1. A computer-implemented method in a controller, for providing a hybrid of virtual port and virtual cell service modes to stations connected to a wireless network, comprising:
- connecting to the wireless network comprising one or more access points;
receiving notification of a request for network access from a station to an access point of the plurality of access points, along with identification information associated with the station;
selecting a service mode to provide to the station based on the identification information, wherein the service modes comprise at least a native cell mode which assigns a BSSID (Basic Service Set IDentifier) for standard operation, a virtual cell mode which assigns a persistent BSSID as a station is serviced by different access points, and a virtual port mode which assigns a unique BSSID for a station; and
assigning a BSSID to the station that corresponds to the service mode responsive to the notification.

Abstract
A controller directing access points to default to a virtual cell service mode which allows seamless mobility for stations in motion around a wireless network is disclosed. Responsive to identifying a first station, the controller logic may dictate tighter controls for the first station by selecting a virtual port service mode. Some embodiments can also select a native cell service mode for devices due to a connection history of the station or a MAC OUI that is incompatible with virtual cell service mode. An initial service mode can be changed due to a condition. Also, the controller provides multiple BSSIDs to each access point.

14. A controller to provide a hybrid of virtual port and virtual cell service modes to stations connected to a wireless network, comprising:
-
an interface to connect to the wireless network and to receive notification of a request for network access from a station to an access point along with identification information associated with the station; a selection module to select a service mode to provide to the station based on the identification information, wherein the service modes comprise at least a native cell mode which assigns a BSSID (Basic Service Set IDentifier) for standard operation, a virtual cell mode which assigns a persistent BSSID as a station is serviced by different access points, and a virtual port mode which assigns a unique BSSID for a station a BSSID module to assign a BSSID to the station that corresponds to the service mode responsive to the notification.
