COMMUNICATION APPARATUS
First Claim
1. A communication apparatus that communicates with an other-party communication apparatus, said communication apparatus comprising:
- a communication unit configured to perform transmission/reception of data with the other-party communication apparatus;
a power switching unit configured to switch a state of power supplied to said communication unit, between a supply state where power necessary for the transmission/reception is supplied and a non-supply state where power necessary for the transmission/reception is not supplied;
a suppression unit configured to suppress data transmission from the other-party communication apparatus; and
a switching control unit configured to cause said power switching unit to switch the state of power to the supply state when the data transmission is not suppressed by said suppression unit, and cause said power switching unit to switch the state of power to the non-supply state when the data transmission is suppressed by said suppression unit.

Abstract
To provide a communication apparatus for achieving further improvements in communication quality and power saving effect, without depending on network environments. A portable terminal (211) as a communication apparatus includes: a communication I/F unit (108) performing data transmission/reception with a transmitter apparatus (203) on a communication protocol having flow control such as TCP; a power control unit (106) switching power on and off to the communication I/F unit (108); and a suppression/resumption control unit (104) determining cycle interval Tc and cycle data size Dc according to communication quality required by a communication application program and, per cycle interval Tc, causing data of cycle data size Dc to be transmitted in a burst state, suppressing data transmission from the transmitter apparatus (203), and causing the power control unit (106) to power off the communication I/F unit (108) while the data transmission is suppressed (T2 to T3), using the flow control mechanism.

23. A communication method using a communication unit that communicates with an other-party communication apparatus, said communication method comprising:
-
performing transmission/reception of data with the other-party communication apparatus, by the communication unit; suppressing data transmission from the other-party communication apparatus; switching a state of power supplied to the communication unit to a supply state where power necessary for the transmission/reception is supplied, when the data transmission is not suppressed in said suppressing; and switching the state of power supplied to the communication unit to a non-supply state where power necessary for the transmission/reception is not supplied, when the data transmission is suppressed in said suppressing.

-
24. A program for communicating with an other-party communication apparatus using a communication unit, said program causing a computer to execute:
-
performing transmission/reception of data with the other-party communication apparatus, by the communication unit; suppressing data transmission from the other-party communication apparatus; switching a state of power supplied to the communication unit to a supply state where power necessary for the transmission/reception is supplied, when the data transmission is not suppressed in said suppressing; and switching the state of power supplied to the communication unit to a non-supply state where power necessary for the transmission/reception is not supplied, when the data transmission is suppressed in said suppressing.

-
25. An integrated circuit that communicates with an other-party communication apparatus, said integrated circuit comprising:
-
a communication unit configured to perform transmission/reception of data with the other-party communication apparatus; a power switching unit configured to switch a state of power supplied to said communication unit, between a supply state where power necessary for the transmission/reception is supplied and a non-supply state where power necessary for the transmission/reception is not supplied; a suppression unit configured to suppress data transmission from the other-party communication apparatus; and a switching control unit configured to cause said power switching unit to switch the state of power to the supply state when the data transmission is not suppressed by said suppression unit, and cause said power switching unit to switch the state of power to the non-supply state when the data transmission is suppressed by said suppression unit.
