Patent ID: 8467754

Claim:
A reception control apparatus comprising: a first oscillator for generating a first clock signal of high frequency; a second oscillator for generating a second clock signal of lower frequency than that of the clock signal generated by the first oscillator with less power consumption than that of the first oscillator; a reception unit for receiving a signal transmitted; a first control unit for controlling the reception unit to receive a signal based on the first clock signal generated by the first oscillator when performing intermittent reception, and to operate based on the second clock signal generated by the second oscillator by instructing to stop the first oscillator when not performing the intermittent reception; a decision unit for counting an average number of clocks of the second oscillator per period based on the first clock signal generated by the first oscillator and for predicting and determining a timing of the next intermittent reception based on the average number of clocks; a measurement unit for measuring a temperature change amount at each timing of the intermittent reception of a predetermined period; and a second control unit for controlling the period of the timing of the intermittent reception based on the temperature change amount measured, wherein when receiving of the intermittent reception is successful, then the measurement unit measures the temperature change amount from a temperature at reception of a previous intermittent reception and the second control unit controls the period of the timing of the intermittent reception based on the temperature change amount; and when receiving of the intermittent reception is failed, then a decision unit determines the timing of the next intermittent reception based on the average number of clocks; the reception unit thereafter receiving another signal.
