Abstract
According to an embodiment of the invention, a mobile communication apparatus includes: a first processor; a second processor; an intermittent receiver that is operated using the first processor; and a timer processing unit that is operated using the first processor and the second processor and configured to determine a start time of an operation thereof by performing a time-out control based on a timer, wherein the timer processing unit sets the timer so that a time-out occurs at a given timing, to perform a first function to be started at the given timing, and wherein the timer processing unit sets the timer so that a time-out occurs at a time when the intermittent receiver is operated, to perform a second function to be started at an arbitrary timing.

A mobile communication apparatus comprising:
- a first processor;
- a second processor;
- an intermittent receiver that is operated using the first processor;
- and
- a timer processing unit that is operated using the first processor and the second processor and configured to determine a start time of an operation thereof by performing a time-out control based on a timer,
- wherein the timer processing unit sets the timer so that a time-out occurs at a given timing, to perform a first function to be started at the given timing, and
- wherein the timer processing unit sets the timer so that a time-out occurs at a time when the intermittent receiver is operated, to perform a second function to be started at an arbitrary timing.
A mobile communication apparatus comprising:
- a first processor;
- a second processor;
- an intermittent receiver that is operated using the first processor;
- a timer processing unit that is operated using the second receiver and configured to determine a start time of an operation thereof by performing a time-out control based on a timer, and
- a power unit configured to control power supply to the intermittent receiver and the timer unit and that is operated by the first processor;
- wherein, when the second processor starts to operate, the second processor activates the first processor to operate the power unit if the first processor is inactive;
- wherein the timer processing unit sets the timer so that a time-out occurs at a given timing, to perform a first function to be started at the given timing, and
- wherein the timer processing unit sets the timer so that a time-out occurs at a time when the intermittent receiver is operated, to perform a second function to be started at an arbitrary timing.
A mobile communication apparatus comprising:
- a first processor;
- a second processor;
- an intermittent receiver that is operated using the first processor;
- an image selector that is operated using the second processor;
- and
- a display configured to display an image data stored in a frame buffer;
- wherein the intermittent receiver intermittently executes a receiving operation including:
- (a) receiving radio wave transmitted from a base station and measuring a quality of the received radio wave;
- (b) determining a quality level by comparing a measured quality with a threshold;
- and
- (c) activating the second processor and transmitting the quality level to the image selector if the quality level differs from a quality level transmitted to the image selector at a previous time,
- wherein, if the image selector receives the quality level transmitted from the intermittently receiver, the image selector selects an image data based on the received quality level to store the selected image data to the frame buffer.

- a first processor;
- a second processor;
- an intermittent receiver that is operated using the first processor;
- an image selector that is operated using the second processor;
- and
- a display configured to display an image data stored in a frame buffer,
- wherein the intermittent receiver intermittently executes a receiving operation including:
- (a) receiving radio wave transmitted from a base station and measures a quality of the received radio wave;
- (b) calculating a weighted average value from the measured quality and a quality measured in the intermittent receiving operation of a predetermined number of times of the past;
- (c) determining a quality level by comparing the calculated weighted average value with a threshold;
- and
- (d) activating the second processor and transmitting the quality level to the image selector if the quality level differs from a quality level determined at a previous time,
- wherein, if the image selector receives the quality level transmitted from the intermittently receiver, the image selector selects an image data based on the received quality level to store the selected image data to the frame buffer.
