Multipoint voice-communication system in quasi full-duplex mode

摘要

The method involves accessing a common transmission resource by user nodes. Access to the resource is organized in time frames, where each time frame comprises a first polling period during which the user nodes having a voice packet transmit (210) an access request, a allocation period during which a control node allocates (220) transmission frames to all or part of the user nodes, and a transmission period during which each user node transmits (230) a voice packet in the allocated transmission frame.
