<p>The present invention relates to a method and system of a method and system for leveraging a 3G authentication to obtain a 2G authentication for a mobile station (135) using a provisional authentication agent (140). The mobile station (135) first establishes a provisional authentication (210, 215) in the 2G wireless communication system (105) using a second set of authentication parameters and based on the provisional authentication, negotiates a 3G authentication (220) with a 3G wireless communication system (115) that the mobile station was previously operating in and had authenticated to. Using the first set of authentication parameters received from the 3G wireless communication network (115), the mobile station (135) completes a true 2G authentication (230) in the 2G wireless communication system (105).</p> |
