Abstract:
A communication terminal (10) including a first communication unit (11) and a second communication unit (12) with a shorter communication distance than the first communication unit (11) includes a presence status detection unit (13) that detects that a distance from a personal computer (50) has changed from a state possible to communicate to a state not possible to communicate for the second communication unit (12), and a communication status control unit (14) that causes a standby interval in intermittent reception performed by the first communication unit (11) to become shorter when a change of the second communication unit (12) from the state possible to communicate to the state not possible to communicate is detected by the presence status detection unit (13). This enables more detailed and accurate tracking of the connection status of the first communication unit (11), which can advance the timing to bring the first communication unit (11) to transition to a disconnection state or a standby state, allowing reduction of power consumption in the first communication unit (11).
