In a communication system that includes a first base station, a second base station, and at least one terminal that makes a connection to the second base station, a connection destination of the terminal that makes a connection to the second base station is efficiently switched. The terminal that makes a connection to the second base station determines received quality of each of a neighboring base station that is positioned in the neighborhood of the second base station and the second base station, and notifies a macro cell base station and the second base station of the received quality. Furthermore, the first base station or the second base station determines whether or not the terminal has to perform handover, based on the received quality. In a case where the handover has to be performed, the first base station determines the connection destination of the terminal, based on the received quality notified from the terminal, and provides a handover instruction.
