User equipment receives and stores configuration information for selection of an evolved packet data gateway (ePDG). The ePDG configuration information includes one or more parameters relating to identification and functions of ePDGs in an HPLMN and/or in one or more VPLMNs. When the UE performs ePDG selection, the UE accesses the ePDG configuration information and then selects an ePDG for access to a core packet network using the ePDG configuration information.
