Abstract:
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication. A user equipment (UE) device may be connected to a first evolved packet data gateway (ePDG) via a first radio access technology (RAT). The UE may evaluate, either periodically or based on a trigger event, an ePDG reselection metric associated with the first ePDG to determine whether selecting a second ePDG different from the first ePDG is viable. The UE may then reselect to a second ePDG based on whether the ePDG reselection metric satisfies one or more selection conditions. Selection conditions may include, for example, a change in the location or public land mobile network (PLMN) of the UE, UE movement between networks, or a connection failure associated with the first ePDG.
