CONSTITUTION:Radio base stations 7, 8 are arranged respectively to radio zones A, B. A master set 9 controls a telephone system. A mobile station management section 9a manages the position information of mobile stations 1, 4. Furthermore, the mobile station management section 9a obtains the position information of the mobile stations 1, 4 via the radio base stations 7, 8. An incoming call control section 9b detects to which telephone set an incoming call comes and informs the arrival of the call to the telephone set. A busy state transfer control section 9c selects a transfer destination telephone set to transfer the incoming call to other telephone set when it reaches a busy telephone set.
