Abstract
A method to optimize the energy consumption of a station (STA)—as for example a laptop, palmtop or a mobile phone—in a network, preferably a WLAN according to the IEEE 802.11 standard where a station (STA) sending Power Save (PS) polls to an Access Point (AP) is characterized—regarding an efficient energy management of the station with a possibly low energy consumption—in that the Access Point (AP) confirms the receipt of a Power Save (PS) poll by sending an acknowledgement frame including information which indicates to the station (STA) whether a frame is stored for it at the Access Point (AP).
Claims11
A method for optimizing energy consumption of a station in a network, comprising:
- the station sending power save polls to an access point;
- and
- the access point, in response to a power save poll received from the station, sending an acknowledgement frame back to the station to confirm reception of the power save poll, wherein the acknowledgement frame includes information which indicates to the station whether a frame is buffered for it at the access point.
A control method in a station which is operable in an energy saving mode and is allowed to connect to a network through an access point, comprising:
- sending power save polls to the access point;
- receiving an acknowledgement frame from the access point in response to a sent power save poll, wherein the acknowledgement frame includes information which indicates whether a frame is buffered for the station at the access point;
- and
- controlling the energy saving mode based on the information included in the acknowledgement frame.
A method for optimizing energy consumption of a station in an access point, wherein the station is operable in an energy saving mode and is allowed to connect to a network through the access point, comprising:
- receiving a power save poll from the station;
- and
- sending an acknowledgement frame back to the station as a response to the power save poll, wherein the acknowledgement frame includes information which indicates to the station whether a frame is buffered for it at the access point, wherein the energy saving mode of the station is controlled based on the information included in the acknowledgement frame.
