ABSTRACT:
A method of packet switched handover in a mobile communication system comprising a terminal, a source node and a destination node comprises negotiating protocol parameters for the destination node on behalf of a new network entity, by communicating with an old network entity whilst the terminal is still connected to the source node; and completing the packet switched handover, such that service interruption on handover is reduced.
