Communication terminal, computer-readable storage medium, and communication method
First Claim
1. A communication terminal comprising:
- a first communication unit having a power supply function by electromagnetic induction;
a second communication unit having a communication capability higher than that of the first communication unit;
a power management unit configured to predict an amount of electric power necessary for the communication with the communication partner terminal by the second communication unit and determine, based on a relationship between remaining power and the predicted amount of electric power, whether to receive power by the power supply function of the first communication unit from a communication partner terminal; and
a communication control unit configured to, if the power management unit has determined to receive the power from the communication partner terminal, control communication with the communication partner terminal by the second communication unit using the power supplied from the communication partner terminal via the first communication unit.

Abstract
A communication terminal includes a first communication unit having a power supply function by electromagnetic induction, and a second communication unit having a communication capability higher than that of the first communication unit. When communicating with a communication partner terminal, it is determined whether to receive power from the communication partner terminal. Upon determining to receive the power by the power supply function of the first communication unit, communication with the communication partner terminal by the second communication unit is controlled using the power supplied from the communication partner terminal by the power supply function of the first communication unit.
