  • Publication number: 20080130542
    Abstract: 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.

  • Publication number: 20080019295
    Abstract: A power saving method applied in a wireless local area network (WLAN) includes an access point and at least one mobile station. The power saving method includes the following steps. The power saving method includes the following steps. One of the at least one mobile station enters an active mode, and sends a query frame to the access point. The access point sends an acknowledgement frame to the one of the at least one mobile station after receiving the query frame and begins timing via a timing module. The access point determines whether there is a data frame to be sent to the one of the at least one mobile station. The access point sends the data frame to the one of the at least one mobile station when the timing module times out if there is the data frame to be sent to the one of the at least one mobile station. The one of the at least one mobile station enters a power saving mode after receiving the data frame.
