A radio channel control section 370 transmits and receives to and from an adjacent base station uplink/downlink channel communication qualities measured by a communication channel transmit/receive section 330 and a mobile station 410, respectively, compares them with predetermined lower and upper threshold values Tl/Th, requests a pilot channel transmit section 350 to decrease and increase the transmission power level of a pilot signal if the threshold value Tl is not reached and the threshold value Th is exceeded, respectively. For a downlink channel, a hand-off parameter is increased and decreased if the threshold value Tl is not reached and the threshold value Th is exceeded, respectively. For an uplink channel, the hand-off parameter is decreased and increased if the threshold value Tl is not reached and the threshold value Th is exceeded, respectively. |
