Abstract

The invention relates to a method for packet switched data transmission in a local network, the local network comprising a mobile node and a plurality of interconnected connection anchor points each with a link at which the mobile node can attach. The method comprises the steps of detecting a movement of the mobile node from a first connection anchor point to a second connection anchor point, the mobile node communicating via a tunneled connection between the first and second connection anchor point, maintaining the existing tunneled connections between the second connection anchor point and the first connection anchor point, and enabling new connections between the mobile node and correspondent nodes using addresses that are topologically correct.
