Abstract: A base station device 31 provided in a general cell 41 is accommodated in a base station controller 21, and a base station device 32 provided in a general cell 42 is accommodated in a base station controller 22. A base station device 33 provided in a boundary cell 43 that is adjacent to both the general cells 41 and 42 is accommodated in both the base station controllers 21 and 22. Frequencies RF#1 and RF#2 are allocated to each of the general cells 41 and 42 and boundary cell 43. Communications conducted by the base station device 33 using the frequency RF#1 is controlled by the base station controller 21, and communications conducted by the base station device 33 using the frequency RF#2 is controlled by the base station controller 22.
