<p>An access node such as a base station is adapted to communicate with a first transmission network and via a data radio channel with a user node. When a second transmission network is connected to the access node, to manage a network layer packet transmitted between the user node and a node of one of the first and second transmission networks, the access node inspects at least one part of the network layer packet, and switches the inspected network layer packet to a node of one of the first and second transmission network or to the user node.</p> |
