Abstract: A dual way communication method adapted for a multipoint transmission structure is presented. A dual way communication channel is turned on for a transmission demanding terminal corresponding to a notice signal when the notice signal from the transmission demanding terminal is detected. Via the dual way communication channel, a dual way demanding message corresponding to the transmission demanding terminal is received, or another dual way demanding message corresponding to the transmission demanding terminal is sent out. The above method can be applied to a system constructed by the multipoint transmission structure or to a master device of the multipoint transmission structure.
