    Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a radio access technology (RAT) upgrade. A UE may initiate a background scan to upgrade RAT while camped on a first system in response to an occurrence of a first condition. The first system may include a first PLMN that operates according a first RAT. The UE may determine a second system operates according to a second RAT that provides upgraded service as compared to the first RAT. The second system may be included in one or more systems found during the background scan.
