1. A user equipment comprising:
a receiver configured to 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, wherein the RRC inactive state is a different state from an RRC connected state and an RRC idle state, and wherein the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure; and
a controller configured to
start the timer upon receiving the RRC release massage, and
perform the RRC resume procedure when the timer expires.
