Abstract:
A radio communication control device includes a radio parameter update determination portion, a transmission power value change portion and a radio parameter update portion. The radio parameter update determination portion determines whether or not to update a radio parameter relating to at least one of a communication frequency and transmission power to a new radio parameter. The transmission power value change portion performs a transmission power change process to change a transmission power value during data transmission to a radio communication station to a smaller value in stages at predetermined intervals when the radio parameter update determination portion determines to update the radio parameter to the new radio parameter. A radio parameter update portion updates the radio parameter to the new radio parameter when the transmission power value change portion changes the transmission power value to a preset lower limit or less.
