摘要： Methods and apparatus for facilitating mobility of the mobile stations in a wireless local area network (WLAN) allows uninterrupted communications as the mobile station moves. The method includes associating (501) a MNIP address (410) with the mobile station; establishing (502) a communications link between the mobile station and a first WLAN AP (109) in a first subnet (117) and associating (503) a first WLAN IP (420) address with the mobile station. Then using (505) the first WLAN IP address for an application that benefits from a persistent connection. Further included is establishing (507) a second communications link between the mobile station and a second WLAN AP 111 in a second subnet (119). When the mobile station is using the application, continuing to use the first WLAN IP address for communicating with the second subnet; and requesting (517) a second WLAN IP address in the second subnet when the persistent connection is no longer needed.
