PROBLEM TO BE SOLVED: To provide a radio data transmission method, its mobile terminal and an interlocking device for different signals. SOLUTION: A radio data transmission method, which includes a radio mobile terminal, an interlocking device for different signals and a server and performs radio data transmission, includes a step (S302) for inputting an identifier which includes an Internet protocol address as an specified instruction and dialing it, at the mobile terminal steps (S304 and S306) for performing synchronization of a radio connection protocol through a circuit exchange data channel between the mobile terminal and the interlocking device for different signals by following the instruction, steps (S312 and S314) for performing a point to point transmission control protocol at the interlocking device according to the identifier, and a step (S316) for releasing a network interface channel according to the Internet protocol of the identifier at an AT processor of the interlocking device. Thus, it is possible to directly be connected to the network interface of an Internet connection port without using a modem while using the circuit exchange data cannel a network entrepreneur likes.
