Abstract: A server, method, and non-transitory computer-readable medium for multi-endpoint design for IMS supported devices. The server includes a memory, a communication interface, and one or more processors operably connected to the memory and the communication interface. The one or more processors are configured to cause the communication interface to simultaneously transmit the incoming call to both (i) the primary device where IP multimedia subsystem (IMS) service is not supported based on user preference or operator policy and (ii) a secondary device, and transmit a message to the primary device to adaptively trigger IMS service for supporting multi-endpoint service.

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.

Abstract: A method, apparatus, and user equipment for wireless communication using evolved data packet gateway (ePDG) communication. The method includes identifying one or more wireless access points and a received signal strength indication for each of the one or more wireless access points. The method also includes identifying which of the one or more wireless access points supports ePDG communication. The method also includes selecting a wireless access point of the one or more wireless access points based on the received signal strength indication and whether the wireless access point supports ePDG communication. The method also includes connecting to an ePDG server through the wireless access point.
