Detecting method and device for saving electrical power consumption of communication device
First Claim
1. A detecting method for saving electrical power consumption of a communication device, comprising:
- providing a receiving end, wherein an operation cycle of the receiving end comprises a hibernation mode and an operation mode;
after a first time period, switching the receiving end from the hibernation mode to the operation mode, wherein the receiving end in the hibernation mode is supplied with a first electric power, and the receiving end in the operation mode is supplied with a second electric power;
switching to the operation mode, wherein the receiving end detects a signal for communication sent from a sending end in a second time period;
keeping the receiving end in the operation mode when receiving a plurality of first signals from the sending end;
switching the receiving end from the operation mode to the hibernation mode if the receiving end does not detect the first signals after the second time period; and
wherein the second time period is determined by a sending time parameter period, a buffer time parameter buf, and a transmission time parameter τ
, and the second time period is (period+buf+τ
).

Abstract
A detecting method and a detecting device for saving electrical power consumption of a communication device are introduced. During each operation cycle, a receiving end is switched between a hibernation mode and an operation mode alternately. The receiving end in the hibernation mode is supplied with a first electric power, the receiving end in the operation mode is supplied with a second electric power, and the first electric power is smaller than the second electric power. The receiving end in the operation mode detects whether there is a first signal from a sending end. If receiving the first signal, the receiving end is kept in the operation mode, and continued to be supplied with the second electric power. If the receiving end in the operation mode does not receive the first signal, the receiving end enters the hibernation mode and is supplied with the first electric power.

5. A communication device, applied in a radio communication system, comprising:
-
a sending end, for providing a plurality of first signals; and a receiving end, for receiving the first signals, wherein an operation cycle of the receiving end comprises an operation mode and a hibernation mode, wherein the receiving end further comprises; a transmitting/receiving antenna; an audio modulation unit, coupled to the transmitting/receiving antenna, for processing the first signals; an electric power unit, for providing electric power required by the operation of the receiving end; a processing unit, coupled to the audio modulation unit, wherein the processing unit is used to count time for switching the receiving end from the hibernation mode to the operation mode after a first time period, when the processing unit is in the hibernation mode, the processing unit determines to supply a first electric power to the communication device, when the processing unit is in the operation mode, the processing unit determines to supply a second electric power to the communication device and detects whether the sending end sends the first signals in the period, if receiving the first signals in the period, the receiving end is kept in the operation mode, and if the receiving end does not receive the first signals in the period, the receiving end is switched from the operation mode to the hibernation mode after a second time period; and wherein the second time period is determined by a sending time parameter period, a buffer time parameter buf, and a transmission time parameter τ
, and the second time period is (period+buf+τ
). - View Dependent Claims (6, 7, 8, 9, 10)
