Abstract
A method and packet data support node in a radio telecommunications network supporting packet data communication between a packet data network and a mobile terminal in radio communication with a first packet control unit. The packet data support node receives a message from the mobile terminal requesting handover to a second packet control unit. A packet flow context detector in the packet data support node detects the number of packet flow contexts currently active in the first packet control unit for supporting the packet data connection. The detector sends a message during handover to the second packet control unit indicating the number of active packet flow contexts. The message is used for activation of a corresponding number of packet flow contexts in the second packet control unit.
