摘要： One embodiment described herein, a method of supporting wireless stations in a wireless distribution system having a portal and one or more access points is described. The method comprises accepting by a first access point (AP) a set of filters from a station; receiving by the first AP signaling that the station enters into an idle mode and signaling the same to a server in the wireless distribution system; forwarding by the first AP the set of filters to the server, the set of filters being applied to messages directed to the station received by the server in the wireless distribution system; receiving a buffered message for the station from the server in response to the buffered message matching at least one of the set of filters; and forwarding the buffered message to the station in response to receiving the buffered message from the server.

摘要： Supporting idle stations in an IEEE 802.11 wireless distribution system. When a station in an IEEE 802.11 wireless distribution system (DS) enters the idle state, it is not associated with any access points (APs) in the DS, Prior to entering the idle state, a station may establish filters indicating what traffic it wishes to receive. These filters are sent to a server in the DS. When a station goes idle, it is associated with a paging server in the DS, which buffers all received for the idle station, and initiates paging of the idle station when such traffic meeting filter criteria is received. When the station exits the idle state by reassociating with an AP in the DS, the server is notified, and forwards the buffered traffic to the station through its AP. The server may be implemented as a process running in a controller or portal in the DS.

摘要： Band steering for multi-band wireless clients. In a wireless digital network having at least one central controller and a plurality of access nodes connected to the central controller, and wherein some of the access nodes support a preferred wireless band and at least one non-preferred wireless band, the central controller identifies wireless client devices capable of multi-band operation, and encourages them to connect to the preferred wireless band. Client devices may be identified as multi-band capable by tracking probe requests. The central controller keeps a list of multi-band capable clients, for example in a database. This information is provided to other central controllers, and to access nodes attached to the central controller. Multi-band capable clients are encouraged to connect on the preferred wireless band for example by having the access nodes not respond to probe requests on the non-preferred wireless bands. Connections made on the non-preferred wireless bands may be moved to the preferred wireless band.
