Communication control device, method of controlling communication, and program
First Claim
1. A communication control device comprising:
- a processing device and a memory containing instructions that, when executed by the processing device, implement;
a communication necessity information acquisition unit configured to acquire communication necessity information indicating necessity to communicate with an external device;
a drive control unit configured to control drive of a first communication unit and a second communication unit on a basis of the acquired communication necessity information, the first communication unit communicating with the external device using a first communication mode, the second communication unit communicating with the external device using a second communication mode capable of transferring data at a rate higher than the first communication mode; and
a communication mode selection unit configured to select a communication mode to perform communication from the first communication unit and the second communication unit based on an amount of communication data predicted from the communication necessity information, so that communication is performed with low power consumption,wherein the drive control unit sets a drive state of the selected communication unit to the active state and causes the selected communication unit to communicate with the external device, and sets the drive state of the non-selected communication unit to a power-saving state and wherein an authentication process for communication with the external device in the second communication mode is performed by communication with the external device using the first communication mode.

Abstract
[Object] To reduce power consumption even more.
[Solution] Provided is a communication control device including a communication necessity information acquisition unit configured to acquire communication necessity information indicating necessity to communicate with an external device, and a drive control unit configured to control drive of a first communication unit and a second communication unit on a basis of the acquired communication necessity information, the first communication unit communicating with the external device using a first communication mode, the second communication unit communicating with the external device using a second communication mode capable of transferring data at a rate higher than the first communication mode. The drive control unit controls a drive state of each of the first communication unit and the second communication unit to be set to one of an active state capable of communicating with the external device, a power-saving state having lower power consumption than the active state, and an inactive state being a power off state.

16. A method of controlling communication, the method comprising:
-
acquiring communication necessity information indicating necessity to communicate with an external device; controlling drive of a first communication unit and a second communication unit on a basis of the acquired communication necessity information, the first communication unit communicating with the external device using a first communication mode, the second communication unit communicating with the external device using a second communication mode capable of transferring data at a rate higher than the first communication mode; and selecting a communication mode to perform communication from the first communication unit and the second communication unit based on an amount of communication data predicted from the communication necessity information, so that communication is performed with low power consumption, wherein a drive state of the selected communication unit is controlled to be set to the active state and to cause the selected communication unit to communicate with the external device, and the drive state of the non-selected communication unit is controlled to be set to a power-saving state and wherein an authentication process for communication with the external device in the second communication mode is performed by communication with the external device using the first communication mode. - View Dependent Claims (17)
