Abstract
A method and apparatus for handling a Local Break Out (LBO) session taking place in a first network between a user equipment and a corresponding node (CN) is provided. For the downlink packets, embodiments include: converting, in a node in the first or the second network, the IP address of the downlink packets from an LHoA to a Global Home Address (GHoA) and routing, from the first node to a second node in the second network, any downlink packets being sent from the corresponding node, so that the downlink packets will arrive at the user equipment having a GHoA. For the uplink packets embodiments include: converting, in a node in the first or the second network, the IP address of the uplink packets from a GHoA to an LHoA and routing, from the second node to the first node, any uplink packets being sent from the user equipment; so that the uplink packets will arrive at the corresponding node with a source address that is an LHoA.
