Filed:

Jan 26, 2004

Appl. No.:

10/765562

Inventors:

Daniel Wong - San Jose CA, US
Gajendra Shukla - Sunnyvale CA, US
Hilton Hong - San Jose CA, US

International Classification:

H04Q007/20

US Classification:

455445000

Abstract:

A device for wirelessly transmitting data under a wireless protocol is contemplated. A remote wireless network device initiates a session with a network. In this manner, information is sent to a gateway associated with the access point that couples the remote wireless network device to the network. When the remote wireless network device moves, data is tunneled between the succeeding gateway and the original gateway, but for those sessions opened at the original gateway. Any sessions associated with the remote wireless network device at the new gateway are processed and maintained by the new gateway without tunneling the data.

US Classification:

370338000, 342126000

Abstract:

A method for wirelessly transmitting data under a wireless protocol is contemplated. An access point topology map is constructed or input. The topology map relates access points that have overlapping coverage areas, and thus, are prone to have remote devices travel between them. The relationships are used to send session parameters regarding a particular wireless device to the access points or gateways that border the zone in which the particular device is presently in. In this manner, information regarding the particular wireless device and open sessions may be present at such gateways or access points if and when the wireless device enters the zone that the gateway or access point is responsible for.

International Classification:

US Classification:

380270000, 713171000

Abstract:

Systems and methods for pre-authenticating a mobile client in a wireless network. Authenticators in a secured section of the wireless network share a master key generated during an authentication session between a mobile client and an authentication server. The shared master key is not allowed to reside on any devices located outside the secured section of the network. Accordingly, the likelihood that the master key may be hijacked is essentially eliminated. A first session encryption key is derived from the master key and used by the mobile client and a first access point during a first communications session. When the mobile client roams to a second access point, a fast authentication process is performed. The fast authentication process retrieves the shared master key and generates a second session encryption key. A full authentication process between the authentication server and the mobile client is not required. The second session encryption key is used by the mobile client and a second access point during a second communications session.
