Abstract

In a re-routing procedure according to the invention, in-stead of establishing a new connection, the context information is modified only in those network elements which the change in routing concerns. The necessary context information about the connection is loaded to the new network element. Additionally, the other network elements participating the connection are informed of the change of the network element.
