The invention also relates to a method of handling communication of packet data on the downlink to a mobile station over a core network comprising packet data support nodes and an access network comprising a radio network control node, {HEAD ~ the handover} involving {TAIL ~ a change} from a packet data support node acting as an old packet data node to a packet data node acting as a new packet data node, which may relate to different packet data support nodes or one and the same packet data support node for example in the case of dual access nodes
