ABSTRACT:
A method for routing data packets to a mobile node in a communication system which includes at least a first subnetwork of a first type supporting a first IP version and a second subnetwork of a second type supporting a second IP version. The mobile node is provided with a set of protocol stacks for handling data packets at least according to the first and the second IP version and with a home address at least according to the first and the second IP version. The home agent intercepts at least data packets addressed to the mobile node's home address according to the first or the second IP version and for encapsulating a data packet addressed to the mobile node in a packet according to the IP version of the foreign network to which the mobile node is attached, for routing the data packet to the mobile node.
