A method for routing traffic within a network for allowing an efficient offloading of LIPA/SIPTO traffic from the core network even upon handoff of a UE to a new cell, wherein the network includes a core network and a LIPA/SIPTO (Local IP Access/Selected IP Traffic Offload) enabled network, wherein traffic between a UE (User Equipment) and the LIPA/SIPTO enabled network—a so called LIPA/SIPTO traffic—is broken out at a local breakout point and wherein a mobility support for ongoing broken out LIPA/SIPTO traffic will be provided by an MMF (Mobility Management Function) for realizing a continuation of the LIPA/SIPTO traffic upon a handoff of the UE from one cell to another cell. The continuation of the LIPA/SIPTO traffic will be performed by a forwarding mechanism providing direct LIPA/SIPTO traffic between local breakout points of different cells. A network for carrying out the method is also described. |
