Abstract: Techniques that provide optimal packet data network gateway selection upon initial attachment of a upon an initial user equipment (UE) attachment via a WiFi Evolved Packet Data Gateway (ePDG) are described herein. In at least one embodiment, a method may include determining, by an ePDG, whether a UE is capable to connect to at least one of a 5G standalone mobile core network and a 5G non-standalone mobile core network; determining, by the ePDG, whether the UE is subscribed to connect to at least one of the 5G standalone mobile core network and the 5G non-standalone mobile core network; and selecting, by the ePDG, a packet data network gateway to support the UE connection based, at least in part, on determining that the UE is capable and is subscribed to connect to at least one of the 5G standalone mobile core network and the 5G non-standalone mobile core network.

Abstract: A computing device receives one or more messages in a secure communication session with a peer device. Security information for the secure communication session includes a first network address associated with the peer device. The computing device detects that a new message in the secure communication session includes a second network address different from the first network address. The computing device validates the new message as part of the secure communication session and sends an informational request to the peer device. The informational request is sent to the peer device at a destination address of the second network address. The computing device receives an update message from the peer device.
