1. A method for authenticating a mobile station for access to a wireless local area network, the method comprising:
- receiving a registration for a mobile station prior to receiving an association request from the mobile station;
storing identification information for a plurality of mobile stations that are to be allowed to associate to the wireless local area network so as to create a white list of authorized mobile stations;
communicating the white list and corresponding passphrases to a network controller of a cellular telephone network;
associating a mobile station that has roamed into a coverage area of the wireless local area network to the wireless local area network; and
receiving from the mobile station a passphrase and using the passphrase to complete connection to the wireless local area network, the passphrase having been communicated from a cellular network controller to the mobile station.

Abstract
A method and system for authenticating a mobile station, such as a dual mode cellular telephone, for access to a wireless local area network is disclosed. The mobile station can be authenticated by registering, and thus pre-authenticating, it with the wireless area network. Registration can comprise providing identifying information regarding the mobile station to the local area network. Access to the local area network facilitates the use of the local area network for communications by the mobile station, such as using VoIP over the Internet.
