Abstract: A radio communication system includes: a visit information storage unit that stores plural visit information elements each indicating information on a visit to a cell visited by a user equipment; an event detector that detects an event that occurs in the user equipment; a cell identifier detector that detects a cell identifier that indicates a cell visited by the user equipment; and a location characteristic determiner that determines a location characteristic of the cell indicated by the cell identifier based on one or more visit information elements corresponding to the cell. The location to characteristic determiner determines the location characteristic of a cell visited by the user equipment when the event detector detects a no-cell-change event other than a cell-change event that indicates a change in the cell identifier.
