WLAN to UMTS handover with network requested PDP context activation
First Claim
1. A method for configuring a context for a connection delivering a packet data service to a mobile terminal via a target wireless access network, wherein the mobile terminal is initially connected to an originating wireless access network, the method comprising:
- providing the packet data service to the mobile terminal via the originating wireless network,attaching the mobile terminal to a core network connected to the target wireless access network by an authentication server to enable a reception of the packet data service via the target wireless access network, andinitiating by the authentication server establishment of a context within the core network connected to the target wireless access network, wherein the establishment of the context in the core network connected to the target wireless access network comprises;
receiving at a packet data gateway of a core network connected to the originating wireless access network an address of a serving packet data service support node or an address of a gateway packet data service support node, wherein the packet data gateway relays packets of the packet data service to/from the originating wireless access network,determining context information by the packet data gateway based on the context information associated to a connection used for providing the packet data service to the mobile terminal via the originating wireless access network, andtransmitting a context activation message comprising the determined context information to the serving or gateway packet data service support node to establish the context in the respective packet data service support node; and
wherein the context is established prior to an attachment of the mobile terminal to the target wireless access network.

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.

14. A communication system for configuring a context for a connection delivering a packet data service to a mobile terminal via a target wireless access network, wherein the mobile terminal is initially connected to and provided with the packet data service through an originating wireless access network, the communication system comprising:
-
the mobile terminal configured to attach to the originating wireless access network and to receive the packet data service via the originating wireless access network, wherein the mobile terminal is further configured to attach to a core network connected to the target wireless access network by an authentication server to enable a reception of the packet data service via the target wireless access network, the authentication server configured to initiate establishment of a context within the core network connected to the target wireless access network, and a packet data gateway of a core network connected to the originating wireless access network, the packet data gateway being configured to receive, as part of the establishment of the context in the core network connected to the target wireless access network, an address of a serving packet data service support node or an address of a gateway packet data service support node, wherein the packet data gateway is further configured to relay packets of the packet data service to/from the originating wireless access network, and the packet data gateway further configured to determine, as part of the establishment of the context in the core network connected to the target wireless access network, context information based on the context information associated to a connection used for providing the packet data service to the mobile terminal via the originating wireless access network, and further configured to transmit, as part of the establishment of the context in the core network connected to the target wireless access network, a context activation message comprising the determined context information to the serving or gateway packet data service support node to establish the context in the respective packet data service support node, wherein the context is established prior to an attachment of the mobile terminal to the target wireless access network.
