    • A wireless communication unit (120) polls (200) a radio access point (110) at a certain frequency. The wireless communication unit (120) then determines (210) whether packets are received in response to the polling and determines (220) the percentage of polls resulting in receipt of packets. The wireless communication unit (120) then adjusts (230) the polling frequency to change the number of polls which result in the receipt of packets. Optionally, the wireless communication unit (120) repolls (240) the radio access point (110) when a packet in not received. Then, the wireless communication unit (120) plays (250) the packet at a certain time. Alternatively, the wireless communication unit (120) receives (310) packets without polling and determines (220) a radion access point frequency at which packets arrive at the radio access point (110). The polling frequency is then set (330) to approximately the radio access point frequency.
    • 无线通信单元(120)以特定频率轮询(200)无线电接入点(110)。 然后,无线通信单元(120)确定(210)响应于轮询是否接收到分组,并且确定(220)导致收到分组的轮询的百分比。 然后,无线通信单元(120)调整(230)轮询频率以改变导致分组的接收的轮询的数量。 可选地,当未接收到分组时,无线通信单元(120)对无线接入点(110)进行补偿(240)。 然后,无线通信单元(120)在一定时间播放(250)分组。 或者,无线通信单元(120)在不轮询的情况下接收(310)分组,并且确定(220)分组到达无线电接入点(110)的无线电接入点频率。 然后将轮询频率设置为大约无线电接入点频率(330)。

    • 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.
