ABSTRACT:
Estimates of a position of a communication device after a specific time are determined according to a position detecting unit that detects a current position of the communication device, a communication status storage unit that stores communication status data indicating a wireless communication status at each position, and the position detected by the position detecting unit. The communication device includes a prediction unit that predicts the wireless communication status at the position with reference to the communication status data, and a prediction processing unit that executes a handling process for disconnection of the communication due to deterioration of the wireless communication status based on a prediction result by the prediction unit.
