The present invention relates to the seamless switch technology of the mobile node route in hybrid network; the present invention mainly solves the problem that the data message can be transmitted tothe object node in a reliable and real-time way when the mobile nodes in the combined network of the radio ad hoc network and the cable network connect the multihop linkable nodes and change. The present invention comprises that: 1) The mobile node obtains the information of the peripheral multihop linkable nodes and confirms the abuttal state with the linkable nodes, and then maintains and describes the state unit doublet of the abuttal relationship with the linkable nodes; 2) The mobile node confirms whether switch preparation is needed according to the present state and the state after theswitch, and implements communication coordination with every linkable node; 3) In the process of implementing communication switch, the switch report is emitted to the original link nodes and the original link nodes transmit the report message according to the early switch preparation after receiving the report and emit the redirection information.
