Abstract:
A method of transferring unsent packets from an old access point to a new access point in a packet-based connection-oriented telecommunications network, in which the access point of a terminal to the network may change during an active connection, the method comprising:buffering at the old access point the packets which the old access point has not sent to the terminal before change of access point; establishing a connection from the old access point to the new access point; and transferring the buffered packets from the old access point to the new access point over said connection; said establishing a connection further comprising: generating a connection establishment signaling required for said connection establishment in a third network element, which is responsible for controlling the change of access point, tunneling said generated connection establishment signaling to the old access point, and transmitting said generated connection establishment signaling from the old access point to the new access point.
