Abstract: A method for providing Link Aggregation Control between a plurality of systems adapted for Link Aggregation is provided. The plurality of systems includes a primary system, a first secondary system, and a second secondary system. The primary system comprises first primary ports being linked to first ports of the first secondary system by first links. Further, the primary system comprises second primary ports being linked to second ports of the second secondary system by second links. The method comprises forming a link aggregation group, wherein the link aggregation group includes at least one first link and at least one second link. A preferred system among the secondary systems having links within the link aggregation group is selected and further, the method comprises setting the status of the primary ports according to the selection of the preferred system.

Abstract: In an embodiment, there is provided a method for the support of IP connections for a User Equipment UE having access to a 3GPP Core Network CN via at least a trusted non-3GPP Access Network AN that does not support Layer 2 signalling and bearer per IP connection, said method comprising: —providing that traffic carried by an IP connection is tunnelled over said AN, through a Layer-2 tunnel associated with said IP connection.

Abstract: The present invention relates to a method and system for link aggregation, in particular, a method for providing Link Aggregation Control between a plurality of systems adapted for Link Aggregation. A method for providing Link Aggregation Control between a plurality of systems adapted for Link Aggregation is provided. The plurality of systems includes a primary system, a first secondary system, and a second secondary system. The primary system comprises first primary ports being linked to first ports of the first secondary system by first links. Further, the primary system comprises second primary ports being linked to second ports of the second secondary system by second links. The method comprises forming a link aggregation group, wherein the link aggregation group includes at least one first link and at least one second link.
