A terminal 100 detects a moving speed of the terminal 100 and discriminates if it is necessary to switch a radio link between a radio link 102 without soft handover and a radio link 103 with soft handover, when it is necessary to switch the radio link, a request to switch states with/without soft handover 106 is sent to a base station 101 , the base station 101 switches the states with/without soft handover based on the request to switch states with/without soft handover 106 , in addition, an instruction to switch states with/without soft handover 107 is sent to the terminal 100 , and the terminal 100 switches the states with/without soft handover based on the instruction to switch states with/without soft handover 107.
