After the average transmission rate of each batch data packet is selected, judge to preset whether value of statistical indicant is less than zero,
In, when default value of statistical indicant is less than zero, determine that in time data transmission window congestion ought occur for network.
Specifically, after completing to count, processor 1001 judges network when time data transmission window according to statistical result
Whether congestion occurs in mouthful.In the specific implementation, processor 1001 chooses the average transmission rate of a lot data packet, preferably
Ground, processor 1001 can refer to the lot sequence of each batch data packet, carry out choosing for average transmission rate successively.
After the average transmission rate for choosing a lot data packet, processor 1001 is fast by the choose first average transmission
Rate is compared with the second average transmission rate of last batch data packet；Wherein, it is more than second in the first average transmission rate
When average transmission rate, the default value of statistical indicant that initial value is zero is added one by processor 1001, is less than in the first average transmission rate
When the second average transmission rate, default value of statistical indicant is subtracted one, for example, default value of statistical indicant is currently 0, processor 1001 choose the
One average transmission rate is 55kbps, and the second average transmission rate of last batch is 60kbps, it is clear that, 55kbs<60kbs,

Timing length it is initial when it is 5 minutes a length of, duration adjustment step value be 30 seconds, then every time when network in data transmission window
When interior generation congestion, processor increases the timing length of energy-saving mode timer 30 seconds.
Processor 1001 can also continue to increase the timing length of energy-saving mode timer, and by energy-saving mode timer
Timing length increase to after preset duration, persistently reduce the timing length of energy-saving mode timer, until be decreased to economize on electricity
The initial duration of mode timers and then secondary its timing length of increase, and so on.For example, energy-saving mode timer is determined
Shi Shichang it is initial when it is 5 minutes a length of, preset duration be 10 minutes, duration adjustment step value be 30 seconds, then when network first
It is secondary in data transmission window occur congestion when, the timing length of energy-saving mode timer is adjusted to 5 minutes by processor 1001
30 seconds, when the timing length of energy-saving mode timer is adjusted to 10 minutes, and network occurred in data transmission window again
When congestion, the timing length of energy-saving mode timer was adjusted to 30 seconds 9 minutes by processor 1001 by 10 minutes, until will timing
Duration is decreased to 5 minutes and then secondary increase.
