<p>A method for supporting relocation of an IP session during a network layer handover in a mobile communication system. In the method, application context information indicating activities that are advantageously executed pro-actively before the network layer handover is sent. The indicated activities are then pro-actively executed in a receiving network node. An advantage of the method and arrangement of the invention is that the pro-active actions, including pre-allocation of some critical resources for seamless handover of an ongoing IP session, facilitate timely implementation of the activities required for handing over an IP session, and/or selection of a target access router.</p> |
