1. A radio quality degradation prediction system comprising:

  • a wireless terminal; and

    a monitoring server,wherein the wireless terminal comprises;

    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 from the monitoring server a radio quality degradation alert at the wireless terminal, andwherein the monitoring server comprises;

    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 the radio quality degradation alert to the wireless terminal.
