1. A method, comprising:
- sending a transport connection establishment request from a first network node to a second network node;
obtaining a node name for said second network node;
detecting a handover condition in said first network node;
obtaining a second address for said first network node;
updating said second address for said first network node to a name service node; and
sending a transport connection migration request to said second network node, said transport connection migration request comprising a token identifying said connection.

Abstract
The invention relates to a method for the performing of handover in a communication system. In the method a transport connection establishment request is sent from a first network node to a second network node. A node name is obtained for the second network node. A handover condition is detected by the first network node. A new address is obtained for the first network node. The new address for the first network node is updated to a name service node. A transport connection migration request is sent from the first node to the second network node. The transport connection migration request comprises a token, which identifies the connection.
