A handover control server (3) calculates a weight function of each peripheral cell based on network configuration information, cell configuration information, a wireless access capacity of a mobile device, and a used resource at each cell measured by base stations (2-1 to 2-3), and notifies a cell list in which there is registered information concerning a weight-function identifier of the peripheral cell associated with a generated peripheral cell, a base station controlling the peripheral cell, a wireless access system of the base station, an edge router accommodating the base station, and a router identifying the edge router, based on weight function information that is a set of a calculated weight function and a weight function identifier for identifying the weight function, weight function information, network configuration information, and cell configuration information. A mobile device (1) measures wireless-line qualities of the peripheral cells registered in the cell list and the cell currently connected, and determines a cell of a handover destination by calculating a peripheral-cell selection parameter using the measured wireless-line qualities, the weight function information, and the cell list.
