Abstract
A method for radio access network (RAN) based notification area (RNA) update for a radio resource control (RRC)_INACTIVE user equipment (UE) in an RRC_INACTIVE state is disclosed. The method includes receiving, by the RRC_INACTIVE UE in the RRC_INACTIVE state, a first list of RAN area identities (IDs) from a first cell; receiving, by the RRC_INACTIVE UE in the RRC_INACTIVE state, identification information broadcast by a second cell, the identification information including a RAN area ID of the second cell and a cell ID of the second cell; and transmitting, by the RRC_INACTIVE UE in the RRC_INACTIVE state, at least one of an inactive-radio network temporary identifier (I-RNTI) and a cell ID of the first cell to the second cell, after determining that the RAN area ID of the second cell does not belong to the first list of RAN area IDs.
