A mobile station ( 200 ) communicating with an access point ( 100 ) includes an association module ( 202 ), a mode switching module ( 204 ), a verifying module ( 206 ), and a recording module ( 208 ). The association module associates with the access point via an original address and a virtual address. The mode switching module switches between an active mode and a power saving mode. The verifying module transmits a first test frame, then transmits a data acquiring frame to the access point to acquire the first test frame, presets a period of time for receiving the first test frame, and determines whether a time when the first test frame is received is after or before the preset period of time. The recording module records whether the access point supports Frame Exchange Sequence (FES) to switch between the active mode and the power saving mode according to a determined result of the verifying module.
