Patent ID: 7983229

Claim:
A method for configuring connection parameters of a connection between a mobile terminal and a target wireless access network, wherein the method is performed during a handover of the mobile terminal between heterogeneous wireless access networks from an originating wireless access network to a target wireless access network and comprises: providing a packet data service to the mobile terminal via the originating wireless access network, maintaining context information on the packet data service in a network node of a core network connected to at least the originating wireless access network, wherein the context information indicates at least quality of service (QoS) constraints of the packet data service, authenticating the mobile terminal at the target wireless access network by an authentication server, and establishing a tunnel for transporting data packets associated to the packet data service between the mobile terminal and a packet data gateway in a core network via the target wireless access network, wherein the tunnel is at least associated to the QoS constraints, wherein the authentication server obtains said context information from said network node maintaining the context information and provides data indicative of the context information to the packet data gateway, and the packet data gateway causes a pre-configuration of at least the tunnel's QoS constraints based on the data received from the authentication server before establishing the tunnel.
