Abstract
A solution for supporting relocation of an IP session of a mobile node during a network layer handover in a mobile communication system. In the method, from the application context information on the mobile node is detected a first set of capabilities of a network node that that facilitate maintaining the IP session. This first set of capabilities is queried from one or more potential next network node. Applicability of the potential next network node to the relocation of the IP session is determined by the capability information on the first set of capabilities.
