PROBLEM TO BE SOLVED: To power-save for communication apparatus.SOLUTION: Defining a start time of one active state A in a communication apparatus at the other side as ta and the present time as t, a state calculation part 14 calculates the time length T up to appoint when the communication apparatus at the other side gets into an active state using the following formula (S51): T=ta+(n+1)(Ta+Ts)-t.(here, n is 0 or a positive integer satisfying the following formula: ta+Ta+n(Ta+Ts)<t<ta+(n+1)(Ta+Ts)).SELECTED DRAWING: Figure 5 |
