Patent ID: 7969931

Claim:
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, and initiating 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, and transmitting 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.
