PACKET DATA SUPPORT NODE AND METHOD OF ACTIVATING PACKET FLOW CONTEXTS DURING HANDOVER

摘要

A method and packet data support node (204) in a radio telecommunications network supporting packet data communication between a packet data network and a mobile terminal (203) in radio communication with a first packet control unit (201 ).The packet data support node receives a message from the mobile terminal requesting handover to a second packet control unit (202). A packet flow context detector in the packet data support node (204) detects the number of packet flow contexts currently active in the first packet control unit (201 ) for supporting the packet data connection. The detector sends a message during handover to the second packet control unit (202) 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.
