Abstract

The invention relates to a method wherein a transport layer association is established. Thereafter, a handover condition is detected in the first mobile node, which obtains a second address. The second address is updated to a first name server node. A query message is sent to a second name server node for an address of the second mobile node. The second address is indicated to the second mobile node. The first mobile node waits for a response from the second name server node or the second mobile node. Upon receiving a new address for the second mobile node from the second name server node, the first mobile node repeats the indication of the second address of the first mobile node to the second mobile node using the new address as a destination address for the second mobile node.
