Mobile Terminal Device And Control Method For Saving Electric Power Of Mobile Terminal Device
First Claim
1. A mobile terminal device that communicates with a base station in one of a power-saving state in which consumption of power supplied from a built-in power supply is suppressed and a normal state in which the consumption of power supplied from the built-in power supply is not suppressed, the mobile terminal device comprising:
- a base station detecting unit that detects a maximum-power received-wave base station of which a received-wave power is maximum;
a base-station-change detecting unit that detects whether the maximum-power received-wave base station detected by the base station detecting unit is changed; and
a power-saving-state transition control unit that controls transition to the power-saving state when the change of the maximum-power received-wave base station is not detected by the base-station-change detecting unit in a predetermined time in the normal state.

Abstract
A mobile terminal device communicates with a base station in one of a power-saving state in which consumption of power supplied from a built-in power supply is suppressed and a normal state in which the consumption of power supplied from the built-in power supply is not suppressed. The mobile terminal device includes a base station detecting unit that detects a maximum-power received-wave base station of which a received-wave power is maximum, a base-station-change detecting unit that detects whether the maximum-power received-wave base station detected by the base station detecting unit is changed, and a power-saving-state transition control unit that controls transition to the power-saving state when the change of the maximum-power received-wave base station is not detected by the base-station-change detecting unit in a predetermined time in the normal state.

6. A control method for saving electric power of a mobile terminal device that communicates with a base station in one of a power-saving state in which consumption of power supplied from a built-in power supply is suppressed and a normal state in which the consumption of power supplied from the built-in power supply is not suppressed, the control method comprising:
-
detecting a maximum-power received-wave base station of which a received-wave power is maximal; detecting whether the maximum-power received-wave base station detected at the base station detecting is changed; and controlling transition to the power-saving state when the change of the maximum-power received-wave base station is not detected at the base-station-change detecting in a predetermined time in the normal state. - View Dependent Claims (7, 8, 9, 10)
