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.
