A determiner determines execution of rerouting. A notifier notifies the execution of rerouting if the determiner determines the execution of rerouting. A searcher executes a rerouting search if the determiner determines the execution of rerouting. A measurer measures the distance by which a navigation device has moved along a guide route, which is a result of the rerouting search by the searcher. In a case in which the determiner determines execution of next rerouting, the notifier notifies the execution of rerouting if the measured distance is longer than a threshold value and does not notify the execution of rerouting if the measured distance is smaller than or equal to the threshold value.

Navigation device for executing rerouting search and notification method

A transmission unit transmits a signal to a relay station. A reception unit receives a signal from the relay station if the transmission unit does not transmit a signal. A control unit determines whether to (1) perform continuous transmission by the transmission unit or (2) perform communication in which transmission by the transmission unit and reception by the reception unit are alternately switched, based on the positional information acquired in the positional information acquisition unit and the communication area information acquired in the communication area information acquisition unit.

Wireless device and communication method for communicating with relay station

A mobile wireless terminal includes a receiver and a controller. The receiver receives communication information including transmission information and destination position information which shows a position of a destination from a base station. The controller is configured to perform control to delay increasingly notification starting time at which the transmission information is started to be provided as a distance between the position indicated by the destination position information received by the receiver and a position of a local station is longer.
