  • Publication number: 20110088078
    Abstract: In the event of an authentication process failure, a mobile station bans a connection profile storing the credentials provided by the mobile station when initiating the failed authentication process, thus affecting how subsequent scans—other than discovery scans—and connection attempts are handled. In the event of an authentication process failure, a mobile station bans or suppresses an access point with which the mobile station initiated the failed authentication process. The mobile station refrains from transmitting any communications addressed to the unique identifier of any banned access point. The mobile station may ignore any communications received from a banned access point. Suppressed access points are occasionally not made available to the mobile station for selection as a target for a connection attempt.

  • Publication number: 20110085447
    Abstract: A power reduction mechanism in a mobile communications device detects the use of a wrong WEP encryption key in the establishment of a WLAN connection between the mobile device and an access point for both static and dynamic IP WLAN profiles. The power reduction mechanism detects an incorrect WEP key; authentication failure; failure to acquire an IP address for dynamic IP WLAN profiles; decryption errors; and broadcast/multicast frames from the handset not being redirected back to the BSS by the AP. Upon such detection, the mobile device takes one or more power conserving actions, e.g., adding the AP/profile to a ban list; attempting WLAN association for a banned AP/profile at longer intervals than for a non-banned AP/profile; skipping an AP/profile on the ban list for a time duration defined by a timer to conserve power; and flagging the banned AP/profile with a special mark to indicate it is banned.
