Therefore, after carrying out energy-saving mode, terminal 40 at first enters " doze " state, then behind process certain hour (Listen interval or DTIM (Delivery Traffic Indication Map) interval), be transformed into (awake) state of reviving, receive beacon.
When indicating that in beacon message access point 30 has the data that corresponding terminal 40 will receive, the Wireless LAN module of terminal 40 transmits the PS-Poll message to access point 30.
So access point 30 is given terminal 40 data passes after receiving PS-Poll.
When the data that will not receive, terminal 40 is converted to " doze " state again.
If in beacon message, indicate the data that do not have corresponding terminal to receive, then directly be converted to " doze " state.
But there are the following problems for this prior art.
Promptly, in the prior art, under energy-saving mode, terminal can't receive the data that will pass to oneself immediately, after access point is preserved certain hour, needs process to authenticate the step of (PS-Poll message) by message at access point and terminal room, could receive data, therefore, transmitting speed is low, and the data passes delay takes place.
In addition, under energy-saving mode, " doze " state frequently switches with " awake " state, though the power consumption of Wireless LAN module own reduces, the actual power consumption of the terminal that Wireless LAN module is installed increases on the contrary.
