Abstract
Disclosed herein are system, method, and computer program product embodiments for implementing prioritized return of a UE to NR RAT from a GSM/UMTS RAT through RAT reselection based approach. An embodiment operates by determining whether the UE is camped on a first radio access technology (RAT), and in response to a determination that the UE is camped on the first RAT, stores a list of frequencies and a plurality of cell reselection parameter values corresponding to the first RAT. The embodiment determines whether the UE is camped on a second RAT and whether one of a plurality of trigger conditions is satisfied, and in response to a determination that the UE is camped on the second RAT and that one of the plurality of trigger conditions is satisfied, performs measurements on one or more frequencies of the list of frequencies. The embodiment performs cell reselection to a cell of the first RAT based at least in part on the measurements and the plurality of cell reselection parameter values.
