Abstract

Embodiments of the present invention provide a method for data transmission between a switch and a terminal, which includes: transmitting data between the switch and the terminal in a bidirectional Frequency Shift Keying (FSK) mode. The embodiments of the present invention provides an FSK processing module, a terminal, and a switch as well. Owning to implementing service data transmission in the bidirectional FSK mode, the speed of the information transmission between the switch and the terminal is greatly improved so as to provide support for developing interaction services with a great amount of data between the switch and the terminal in communication plane.
