Abstract
A method, apparatus and computer program product receive an application flow comprising a source flow and a supplementary flow from a core network. The method, apparatus and computer program product receive a flow payload indication from the core network. The method, apparatus and computer program product determine whether the application flow is to be transmitted via a unicast transmission or a multicast transmission. The method, apparatus and computer program product determine whether the supplementary flow is droppable based on the flow payload indication and whether the application flow is to be transmitted via a unicast transmission or a multicast transmission. The method, apparatus and computer program product cause only the source flow to be transmitted in a circumstance where the supplementary flow is droppable.
