COMMUNICATION APPARATUS AND COMMUNICATION METHOD
First Claim
1. A communication device for transmitting and receiving data to and from a communication terminal device by transmitting a signal for establishing transmission and reception of the data to the communication terminal device when the communication terminal device, which alternately switches between an active state and a sleep state, is in the active state, the active state being a state in which communication is possible, and the sleep state being a state in which communication is not possible, the communication device comprising:
- a power saving control unit configured to determine a transmission period in such a manner that the transmission period during which the signal is transmitted is increased as a power value difference increases which is a value obtained by subtracting a total power consumption value of a power consumption appliance including the communication terminal device from an available power supply value to the power consumption appliance; and
a communication interface unit configured to transmit the signal containing information indicating the determined transmission period to the communication terminal device so as to set the communication terminal device in the active state with a period according to the determined transmission period.

Abstract
An energy controller (10) as a communication device for transmitting and receiving data by transmitting a signal for establishing transmission and reception of the data to network-connected home appliances (11a to 11c), the energy controller (10) including: a power saving control unit which determines a transmission period such that the transmission period during which the signal is transmitted is increased as a power value difference increases, which is a value obtained by subtracting the total power consumption value of a power consumption appliance from available power supply value to the power consumption appliance including the network-connected home appliances (11a to 11c); and wireless communication IF (22) for transmitting the signal containing the information indicating the transmission period to the network-connected home appliances (11a to 11c) in order to set the network-connected home appliances (11a to 11c) in an active state with a period according to the transmission period.

12. A method of communication for transmitting and receiving data to and from a communication terminal device by transmitting a signal for establishing transmission and reception of the data to the communication terminal device when the communication terminal device, which alternately switches between the active state and the sleep state, is in the active state, the active state being a state in which communication is possible, and the sleep state being a state in which communication is not possible, said method comprising:
-
determining a transmission period in such a manner that the transmission period during which the signal is transmitted is increased as a power value difference increases which is a value obtained by subtracting a total power consumption value of a power consumption appliance including the communication terminal device from an available power supply value to the power consumption appliance; and transmitting the signal containing information indicating the determined transmission period to the communication terminal device so as to set the communication terminal device in the active state with a period according to the determined transmission period.

13. A non-transitory computer-readable recording medium having a computer program recorded thereon for transmitting and receiving data to and from a communication terminal device by transmitting a signal for establishing transmission and reception of the data to the communication terminal device when the communication terminal device, which alternately switches between an active state and a sleep state, is in the active state, the active state being a state in which communication is possible, and the sleep state being a state in which communication is not possible, the program causing a computer to execute:
-
determining a transmission period in such a manner that the transmission period during which the signal is transmitted is increased as a power value difference increases which is a value obtained by subtracting a total power consumption value of a power consumption appliance including the communication terminal device from an available power supply value to the power consumption appliance; and transmitting the signal containing information indicating the determined transmission period to the communication terminal device so as to set the communication terminal device in the active state with a period according to the determined transmission period.
