Abstract
The invention is directed to a communication network wherein a direct tunnel may be formed between a user equipment and a gateway support node, bypassing an intermediate serving support node. If, however, the gateway node should be outside of the actual communication network to which the user equipment is connected, a two-tunnel concept is used wherein a tunnel is provided between the user equipment and the serving support node. Likewise, when receiving a request for Lawful Interception, the tunnel formed between the user equipment and the gateway node is reconfigured to be directed to the serving node for guiding all user traffic and control signaling via this serving node.
