  • Patent number: 11924698
    Abstract: A method for a user equipment (UE) for cell selection while the UE is in a radio resource control (RRC) Inactive state is provided. The method receives, via control signaling, a configuration indicating a target frequency carrier and a corresponding target core network (CN) type. The method then causes the UE to transition from an RRC Connected state to the RRC Inactive state based on the received configuration. While the UE is in the RRC Inactive state, the method selects a suitable cell among a plurality of suitable cells that are associated with the target frequency carrier. The method selects the suitable cell irrespective of the received target CN type.
