The UE comprises processing circuitry, which determines whether the UE, being located in a first radio access network notification area, first RNA, is moving to a second radio access network notification area, second RNA, different from the first RNA. The UE is in an inactive state out of an idle state, a connected state and the inactive state the user equipment can be in. The UE further comprises a transmitter, which transmits identification information on the first RNA to a second radio base station of the second RNA, when determining that the UE is moving to the second RNA. The UE further comprises a receiver which receives from the second radio base station UE related context information usable by the UE to exchange uplink and downlink data with the second radio base station.
