Abstract
A method for facilitating communications between wireless networks is provided that includes communicating with a mobile station and transferring a communication session from a first wireless link to a second wireless link. The mobile station is operable to negotiate a first wireless link with a first wireless network, to establish a communication session with a device using the first wireless link, and to facilitate a session handoff with a second wireless link with the second wireless network using the second wireless interface. The handoff is enabled by associating the first wireless link to the second wireless link.
