Abstract

The invention discloses a method, a device and a system for data transmission based on different links between heterogeneous networks. The method comprises the steps that a receiving terminal sends a message to a network side based on a virtual network card address; one of communication network links corresponding to at least two network cards inserted at the terminal respectively is selected, wherein the communication network links corresponding to at least two inserted network cards respectively are different links between the heterogeneous networks; the virtual network card address serving as a source address in the message is converted to a network card address of the network card corresponding to the selected communication network link; and the message after source address conversion is sent to the network side through the selected communication network link. With the adoption of the technical scheme, the switching efficiency of different communication network links between the heterogeneous networks can be improved better.
