3. A radio base station performing radio communications with a mobile terminal, comprising:
-
a transmission part configured to transmit a change request signal to the mobile terminal so that a communications condition in the mobile terminal is changed;
a setting part configured to set a communications condition of the radio base station; and
a measurement part configured to measure a signal quality of a signal received from the mobile terminal, wherein after the communications condition is changed to another communications condition, the other communications condition is returned to the communications condition before the change using the setting part if the signal quality continues to be more degraded than a predetermined value for more than a predetermined period. - View Dependent Claims (4, 5, 6, 7)
