The invention provides a UTN network fusion method based on the IP technology. The UTN network fusion method comprises multiple network elements and a UTN network; the network elements belong to the UTN network; the method comprises the following steps: S1, any network element adopts a BGP-LU protocol; S2, all network elements in the UTN network issue label routing of device identifiers (which aregenerally loopback addresses) into the network by adopting the BGP-LU protocol; S3, any network element in the UTN network obtains the label routing of the loopback addresses of the other network elements in the network through a BG-LU protocol; and S4, any network element A and any network element B in the UTN network issue the loopback label routing through the BGP-LU protocol, the network element A obtains the loopback label routing of the network element B based on target service, the network element A and the network element B have the condition of establishing a dynamic PW after the loopback label routing is su
