Mobile node compares current detected channel information of selected physical layer with preset trigger condition, and determines whether the base station of satisfying triggering condition belongs to current located sub network of the mobile node in order to decide whether it is needed to trigger network layer switching. If trigger is needed, then switching indication is sent to network layer, and dual links are built for each mobile node. When witching indication being received in network layer, disconnecting only one link in already built dual links, mobile node builds a new link. Then, using new built link, mobile node carries out network registration to home and network layer switching. Then, the other link is disconnected and another new connection in new sub network is built. The method can actively trigger startup of switching network layer precisely from low layer so as to raise switching speed and reduce package loss under condition of uninterrupted communication.
