FAST CONTEXT ESTABLISHMENT FOR INTERWORKING IN HETEROGENEOUS NETWORK

摘要

The invention relates to a method for configuring connection parameters of a connection between a mobile terminal and a target wireless access network in a handover between heterogeneous wireless access networks, wherein the mobile terminal is handed over from an originating wireless access network to a target wireless access network. Moreover, the invention provides a packet data gateway and an authentication server which are adapted to participate and execute a part of the steps of the configuration method. To provide a solution for establishing connection to a wireless access network, as for example a WLAN, as fast as possible, in particular in a handover, the invention proposed to pre-configure a tunnel to be established between a packet data gateway and the mobile terminal for packet data service provision via the target wireless access network based on context information already maintained for the packet data service.
