A user equipment, method, and apparatus for controlling user equipment receive, from a base station included in a network, a radio resource control (RRC) release message that causes the user equipment to transition to an RRC inactive state in which context information of the user equipment is maintained in the network. The RRC inactive state is a different state from an RRC connected state and an RRC idle state, and the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure. The timer is started upon receiving the RRC release massage, and the RRC resume procedure is performed when the timer expires.
