Abstract: An embodiment of this disclosure provides a user equipment (UE) for managing handovers between different networks. The UE includes a memory and at least one processor operably connected to the memory. The at least one processor is configured to establish security associations with an evolved data packet gateway (ePDG) over a Wi-Fi network. The at least one processor is also configured to indicate MOBIKE support and a specific timer value corresponding to a specific period of time for maintaining the security associations. The at least one processor is also configured to, after establishing the security associations, perform a handover from the Wi-Fi network to a long term evolution (LTE) network. The at least one processor is also configured to maintain the security associations for the specific period of time corresponding to the specific timer value after performing the Wi-Fi to LTE handover and disconnecting from the Wi-Fi network.

Abstract: A method of operating user equipment (UE) for detecting network capability. The method comprises identifying a preferred mode for a voice over long-term evolution (VoLTE) call handover operation from an LTE network to a non-LTE network in a first communication network. The preferred mode is associated with the first communication network. The method further comprises initiating a VoLTE call in a second communication network different than the first communication network, determining whether the second communication network is capable of supporting the preferred mode associated with the first communication network, and one of changing and maintaining the preferred mode based on a result of the determination.
