Abstract
This document describes techniques and apparatuses for handling Public Land Mobile Network (PLMN) selection while user equipment is in an inactive mode at a radio resource control layer. In aspects, the UE performs a cell-selection procedure that selects a first cell that serves a first Public Land Mobile Network (PLMN). The UE establishes a radio connection to the first PLMN. The UE transitions from a connected mode at a radio resource control layer to an inactive mode at a radio resource control layer. After a period of time, the UE performs a cell-reselection procedure that selects a second cell that serves a second PLMN. The UE determines if the second PLMN is an equivalent PLMN to the first PLMN. If the second PLMN is an equivalent PLMN to the first PLMN, the UE sends an indication to a lower layer that triggers an action.
