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.
