Abstract
The invention relates to a connection-oriented packet-based communication network, in which the terminal and the network access point of the terminal may move in the network. When the access point of the terminal changes during an active connection, the routing connection can also be changed from an old access point to a new one. The old access point may comprise buffered cells, which can be transferred to the new access point without packet loss. A connection from the old access point to the new one is established dynamically, when required. The connection establishment is controlled by a third network element, which is responsible for controlling the change of access point. The old access point can be arranged to send signaling messages and to establish a connection without requiring any additional intelligence at the access point. Upon the connection being established, the old access point sends buffered unsent packets to the new access point.
