Abstract: Various communication systems may benefit from improved handover. For example, it may be helpful to manage a list candidate cells to which a user equipment may be handed over. A method may include receiving at a user equipment a list of prepared candidate cells from a source cell. The method may also include transmitting the list of prepared candidate cells from the user equipment to a target cell after or during handover from the source cell to the target cell.

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.

Abstract: An embodiment may comprise: transmitting, by a user device in a low activity state a type of the low activity state being according to an anchor access node, a random access message to a network node providing a target cell of a cell reselection. The method may also comprise, in response to receiving a random access response for the random access message from the network node providing the target cell, transmitting, to the network node providing the target cell, a radio connection reactivation request, the reactivation request comprising an indication of an anchor access node of the user device. The method may also comprise, in response to the radio connection reactivation request, receiving a radio connection reactivation message indicating a radio connection reactivation to the anchor access node as a logical link associated with a radio link provided by the target cell of the cell reselection or receiving an inactivation message.
