A radio quality degradation prediction system includes a wireless terminal and a monitoring server. The wireless terminal includes a positioning unit that determines a position of the wireless terminal and notifies the monitoring server of movement history of the wireless terminal via a wireless network, and a user notification unit that gives a warning to a user upon receiving a radio quality degradation alert at the wireless terminal. The monitoring server includes a future position prediction unit that predicts a future position of the wireless terminal based on the movement history of the wireless terminal, a radio propagation prediction unit that estimates radio quality in a service coverage area by using a radiowave propagation simulator, and a quality degradation prediction unit that predicts degradation of radio quality at the future position of the wireless terminal and transmits a radio quality degradation alert to the wireless terminal.
