The method includes transitioning from a radio resource control (RRC) inactive (RRC_INACTIVE) state to an RRC idle (RRC_IDLE) state upon determining that the UE has failed to find a suitable cell and camped on an acceptable cell; and discarding a radio access network (RAN) notification area (RNA) configuration that comprises at least one of a list of tracking area identities (IDs) or a list of RAN area IDs in response to the transitioning from the RRC_INACTIVE state to the RRC_IDLE state. The acceptable cell fulfills a minimum set of requirements to initiate an emergency call and to receive one or more Earthquake & Tsunami Warning System (ETWS) and Commercial Mobile Alert System (CMAS) notifications. The suitable cell provides normal services. The acceptable cell provides limited services."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for RRC state transition","description":"A user equipment (UE) and a method performed by the UE are provided.
