Claim:
A mobile station for communicating with a wireless local area network (WLAN) device over a communication system, the mobile station comprising: a storage system; at least one processor; and one or more modules, wherein the one or more modules are stored in the storage system and configured to be executed by the at least one processor, the one or more modules comprising: a detection module configured for detecting a media access control (MAC) management protocol unit (MMPDU) over the communication system between the mobile station and the WLAN device; an address determination module configured for determining whether the MMPDU comprises a spurious data frame posing as the mobile station to the WLAN device, wherein the determination is based at least partly on a comparison of a source address and a destination address of the MMPDU with a network address of the mobile station and a network address of the WLAN device, respectively; a transmission module configured for transmitting a request data frame having a highest priority in a current connection state between the WLAN device and mobile station to the WLAN device; and a response module configured for determining whether the WLAN device is under attack by the spurious data frame according to whether the response module has received a response data frame from the WLAN device.
