RADIO CONTROLLER, MOBILE COMMUNICATION SYSTEM, BASE STATION, MOBILE COMMUNICATION METHOD, AND MOBILE COMMUNICATION PROGRAM

摘要

A radio controller (10) performs call connection when a connection request is sent from a UE (30) that exists in a macrocell accommodated by a macrocell base station (20b). Thereafter, when the radio controller (10) receives the connection request from the UE (30) that exists in the macrocell accommodated by the macrocell base station (20b), the radio controller (10) searches for a femtocell that is adjacent to or overlaps the macrocell in which the UE (30) exists and a femto base station (20a) that accommodates the femtocell. The radio controller (10) instructs the searched femto base station to resume. The radio controller (10) then instructs the UE (30) to be handed over to the femtocell.
