Abstract
The present invention relates a voice communication method between a plurality of users sharing the same transmission band. The resource is accessed by time division under the supervision of a control node. During a polling step, any user wishing to speak transmits (210) a request to the control node. The control node allocates (220) transmission frames to the requesting users or merely to some of these users. Users allocated a transmission frame can then transmit (230) a voice packet to the respectively allocated frames thereof. The transmission frames are interleaved temporally so as to give the impression of full-duplex communication during voice reproduction.
