Abstract

The present invention is a power saving method for wireless network communication which is applicable to wireless network equipment comprising of the following steps: receiving the frame in wireless network; getting the frame header in frame; according the frame header, judge whether the frames in channel is useful or not; if the received frame is useless, stopping receiving the left parts of the frame or the left frames; according to the frame header, calculating the duration time of left parts in the frame or the left frames; entering power saving status automatically; finally, returning to active status, after the channel is idle again.

Claims

1. A power saving method for wireless network communication applicable to wireless network equipment, comprising the steps of:

receiving a complex number frame in a wireless network;

getting a complex number frame header in the complex number frame;

judging whether the complex number frame is useful or not in accordance with the complex number frame header;

changing the status of the wireless network equipment between active and power saving.

2. The power-saving method of wireless network communication as claimed in claim 1, wherein the complex number frame header comprises the frame rate, the frame length, the destination address.

3. The power-saving method of wireless network communication as claimed in claim 1, wherein, if the received frame is useful, the station will continue to receive the left parts of the frame until the end and accomplish the corresponding operation.

4. The power-saving method of wireless network communication as claimed in claim 1, wherein, if the received frame is useless, further comprises the steps of:

stop receiving the left parts of the complex number frame or the left of the complex number frame;

calculating the duration time of left parts in the complex number frame or the left of the complex number frame in accordance with the complex number frame header;

entering power saving status automatically; and

returning to active status, after a channel of the wireless network equipment is idle again.

5. The power-saving method of wireless network communication as claimed in claim 1, wherein the wireless network equipment consists of a medium access control (MAC) layer, a physical layer, an analog circuit and/or the RF circuit.
