Abstract
The invention relates to a method for configuring a context for a connection delivering a packet data service to a mobile terminal via a target wireless access network. The mobile terminal is initially connected to an originating wireless access network and the packet data service may be provided to the mobile terminal via the originating wireless network. Moreover, the invention provides an authentication server, a packet data gateway and a packet data service support node which participate in the context configuration method. To provide a method that allows establishing connection for packet service delivery to a mobile terminal from a wireless access network, as for example a UMTS, as fast as possible the invention suggests to preconfigure service provision of the packet data service via the target wireless access network by establishing a context prior to the mobile terminal connecting to the target wireless access network.
