Abstract
The present invention relates to a packet data support node () with a serving functionality and supporting over at least a first radio access network. It comprises mobility handling means and session handling means. It further comprises detecting means, in communication with said mobility handling means and with said session handling means, which are adapted to detect or establish initiation of a handover of a mobile station from the first or source radio access network. The session handling means are adapted to keep information about support for a direct tunneling functionality between the gateway packet data support node and the first radio access network. The detecting means are adapted to, upon detecting initiation of an HO from a first mode supporting direct tunneling () activate initiation of a reset of the direct tunnel and set up of two tunnel tunnels (A,B) replacing said direct tunnel (), each having a respective end point in the packet data support node.
