Abstract
A user equipment (UE), method, and non-transitory computer-readable medium for fast VoWiFi handoff using internet key exchange (IKE) v2 optimization. The UE includes a memory and one or more processors operably connected to the memory, wherein the one or more processors are configured to determine reference signal received power (RSRP) for a long term evolution (LTE) signal and reference signal strength indicator (RSSI) for a WiFi signal, in response to at least the RSSI of the WiFi signal being greater than an RSSI threshold, perform a pre-setup of the IPsec tunnel, determine whether a handoff is to be performed, and in response to a determination that the handoff is to be performed, perform a completion of the IPsec tunnel.
