Patent ID: 7313420

Claim:
A mobile terminal, comprising: a transmitter/receiver configured to transmit/receive a signal to/from a base station; a reception state measurement unit configured to measure a reception state of the signal from the base station received by the transmitter/receiver; a movement state measurement unit configured to measure a movement state of the mobile terminal; and a reception period controller configured to control reception periods for receiving a control signal transmitted from the base station by the transmitter/receiver, based on a reception state measurement result determined by the reception state measurement unit and a movement state measurement result measured by the movement state measurement unit, by performing a first and second control process, wherein when the movement state is a low-speed state, the first control process shortens a low-speed reception period as the reception state degrades, when the movement state is a high-speed state, the second control process shortens a high-speed reception period as the reception state degrades, and when the reception state is constant, the high-speed reception period is shorter than the low-speed reception period.
