A wireless communication system provided with mobile terminals and base stations that are configured to manage cells to which said mobile terminals are configured to connect, comprising: a new cell detection unit that is configured to detect, from among neighbor cells that are adjacent to cells to which said mobile terminals are connected, new cells that have newly started or whose operation has resumed or whose geographical range has changed; and a neighbor cell list generation unit configured to preferentially register new cells that have been detected by said new cell detection unit in neighbor cell lists in which are registered neighbor cells that are candidates for handover destinations of said mobile terminals, characterised in that: said mobile terminals are configured to measure wireless quality of cells to which their own terminals are connected and said neighbor cells, and when measurement information of wireless quality of cells to which their own terminals are connected and the neighbor cells satisfies predetermined conditions, report measurement information of wireless quality of the neighbor cells to said base stations; said new cell detection unit is configured to detect said new cells based on the numbers of reports of measurement information of wireless quality that is reported from said mobile terminals for each neighbor cell; wherein said neighbor cell list generation unit is configured to: when new cells that have not yet been registered in said neighbor cell lists have been detected by said new cell detection unit, calculate for each said new cell the rate of increase over time of the number of reports of measurement information of wireless quality that is reported from said mobile terminals; and preferentially register said new cells in neighbor cell lists in the order of higher rate of increase over time. a new cell detection unit that is configured to detect, from among neighbor cells that are adjacent to cells to which said mobile terminals are connected, new cells that have newly started or whose operation has resumed or whose geographical range has changed;
