In a Wireless Local Area Network (WLAN), roaming from one access point (102) to another (103, 104, 105) by a mobile station (110) without interruption to network service may be facilitated by frequently performing background scans to find neighboring access points (103, 104, 105) while the mobile station (110) is associated to the WLAN. Frequent background scanning, however, depletes battery-life. By dynamically adjusting the background scanning interval during the mobile station's (110) association to the WLAN, the mobile station's (110) immediate need for network connectivity performance may be met, while simultaneously prolonging battery-life. For example, by using a shorter background scanning interval during a telephone conversation, network connectivity performance may be maintained throughout the call. Longer background scanning intervals may be used during periods when interruptions to network connectivity may be better tolerated. |
