Methods and apparatuses are provided for configuring UE information. The method may include: after UE is controlled to switch from an RRC connected state to an RRC inactive state, a radio notification area is determined, where the radio notification area indicates a set of one or more cells and the UE in the RRC inactive state moving among the cells in the radio notification area does not cause a cell handover; and UE information of the UE is sent to all base stations within the radio notification area. The UE information of the UE in the RRC inactive state is synchronously configured to other base stations within the radio notification area, such that the base stations may accurately and efficiently determine the RRC state of the UE, thereby improving the transmission efficiency between the base station and the UE.
