A method and apparatus for handling security information between a wireless device and a network for a fast RRC release procedure in a wireless communication system will be provided. A core network node in a wireless communication system receives, from a radio access network (RAN) node, a UE context resume request message including a fast Radio Resource Control (RRC) release indication.
