An embodiment of the present disclosure provides a method for service transmission, including that: a transmission device determines that at least one first radio access technology in multiple radio access technologies is in an active state; and the transmission device performs service transmission by using the at least one first radio access technology. In such a manner, in the embodiment of the present disclosure, the transmission device determines that the at least one first radio access technology in the multiple radio access technologies is in the active state, and performs service transmission by using the radio access technology in the active state, so that the efficiency of the service transmission may be ensured.
