Abstract

The present invention relates to a packet data support node (10A) in a core network and connectable to at least one radio access network over a radio network control node. The packet data support node (10A) comprises duplicating means (12A) for duplicating original downlink data packets intended for a mobile station for which a hand-over is performed from the packet data support node acting as source node to a packet data support node acting as target node, control means (HA) for activating sending of the duplicated data packets to the packet data support node acting as a target node for forwarding to the mobile station such that the original downlink data packets are sent to the mobile station over a source radio access node from the source packet data node (10A). The duplicated data packets are sent to the mobile station over a target radio access node from the packet data source node acting as target node.
