A radio communication system includes at least one user equipment, multiple base stations including a first base station that can execute radio resource control of the user equipment, a second base station that does not execute radio resource control of the user equipment, at least one gateway apparatus, and a switching station that controls a user plane path. The switching station transmits a non-access stratum message to the user equipment through a control plane path established between the first base station and the user equipment in a case in which it is decided that the user plane path should be released, the non-access stratum message instructing the user equipment to release the user plane path.
