Abstract

A radio communication system capable of, in a case where a base station device is movable, easily estimating the location of a base station device and easily estimating the location of a user equipment device using the estimation results, and also provide a user equipment device, a base station device, and a management device included in the radio communication system. In addition to an E-SMLC for UE for use in location estimation of a target UE, an E-SMLC for eNB for use in location estimation of an eNB is provided. The E-SMLC for eNB estimates location information of an eNB in an E-UTRAN and performs a process, such as the management of moving of a target eNode B_s and a target eNode B_uu based on the estimated location information.
