Abstract
Even in an apparatus connected to another apparatus which periodically transmits a command, a mode transition such as transition to a power saving stand-by mode can be performed. A mode change for Bluetooth communications and a mode change in a stand-by state are performed in cooperation with each other to efficiently switch between stand-by modes.
Claims8
An apparatus having a communication function, comprising:
- a first switching device adapted to switch between a power save wireless communication mode and an active wireless communication mode;
- a second switching device adapted to switch between a normal stand-by mode and a power save stand-by mode of the apparatus in accordance with the switching by said first switching device;
- a notifying task adapted to notify a state of said apparatus to another apparatus in response to an inquiry from the other apparatus;
- and
- an execution task adapted to selectively execute a first process of notifying the inquiry from the another apparatus to said notifying task, and a second process of generating an inquiry about the state of said apparatus in place of the inquiry by the other apparatus, and for notifying the generated inquiry to said notifying task in accordance with the switching of communication modes by said first switching device.
A method of controlling an apparatus having a communication function, comprising:
- a first switching step of switching between a power save wireless communication mode and an active wireless communication mode;
- a second switching step of switching between a normal stand-by mode and power save stand-by mode of the apparatus in accordance with the switching by said first switching step;
- a notifying step for notifying a state of said apparatus to another apparatus in response to an inquiry from the other apparatus;
- and
- an execution step of selectively executing a first process of notifying the inquiry from the other apparatus to said notifying step, and a second process of generating an inquiry about the state of the apparatus in place of the inquiry by the other apparatus, and notifying the generated inquiry to the notifying step in accordance with the switching of communication modes by said first switching step.
A storage medium storing a program for controlling an apparatus having a communication function, the program comprising:
- a first switching step of switching between a power save wireless communication mode and an active wireless communication mode;
- a second switching step of switching between a normal stand-by mode and a power save stand-by mode of the apparatus in accordance with the switching of the first switching step;
- a notifying step for notifying a state of said apparatus to another apparatus in response to an inquiry from the other apparatus;
- and
- an execution step of selectively executing a first process of notifying the inquiry from the other apparatus to said notifying step, and a second process of generating an inquiry about the state of the apparatus in place of the inquiry by the other apparatus, and notifying the generated inquiry to the notifying step in accordance with the switching of communication modes by said first switching step.
