The present invention relates to a communication system (1) . In accordance with an embodiment of the invention, the communication system comprises:
- a roaming mobile node (UE) configured to select a particular access network (21, 31) based on handover data exchanged with a handover service node (MIIS, PoS1, PoS2), and to attach to the particular access network, thereby yielding a particular network location,
- a home agent (HA) configured to provide mobility support to the mobile node, and further configured to keep track of the particular network location for the mobile node, and to tunnel traffic bound to a home network address (HoA) held by the mobile node in a home subnet (11) towards the particular network location,
wherein the mobile node is further configured to encode, respectively decode, the handover data into, respectively from, mobility messages exchanged with the home agent and/or with a foreign agent (FA1, FA2) that provides local mobility support to the mobile node at the particular network location. The present invention also relates to a mobile node, and to a method for managing mobility of a roaming mobile node.
