A preferred embodiment comprises a method of cutting unnecessary network tunnels. In a mobile network system, transmitting data packets through a tunnel is an effective way to provide network location privacy. An optimization method is proposed to consolidate two tunnels connecting with a network element such as a first distributed local mobility anchor (D- LMA). The first D-LMA informs a data packet sender such as a second D-LMA of the destination address saved in the first D-LMA. The second D-LMA updates its destination address accordingly and sends subsequent data packets to the destination directly. By applying this optimization method, a network system provides a further optimized route for data packets as well as location privacy.entechnical documentation
