A highly-mobile user equipment (UE) may use a cellular connection over a wireless local area network (WLAN) connection. For example, when a candidate WLAN access point (AP) is encountered, the UE first ensures that the WLAN AP is present in the last two WLAN AP scans performed at least a threshold duration apart. The difference in the Received Signal Strength Indicator (RSSI) of a candidate WLAN AP over the last two WLAN AP scans is compared to a threshold. If the difference in RSSI is greater than the threshold, the WLAN AP is identified as likely having a coverage area that will be exited by the UE relatively soon and the WLAN AP is therefore removed as a candidate. In contrast, if the difference in RSSI is not greater than the threshold, the WLAN AP is identified as likely having a coverage area that will continue to include the UE for a suitable duration, and thus the UE maintains the WLAN AP as a candidate. In the event that one or more candidate WLAN APs are maintained, the UE initiates a WLAN connection with a selected candidate WLAN AP.
