Patent ID: 8787345

Claim:
Voice communication method between a plurality of users equipped with radio terminals as user nodes, which access a common transmission resource and are controlled by a control node, the access to said resource being organised in time frames, the method comprising: in a first period of each time frame, performing a polling period, during which the user nodes having a voice packet to transmit send the control node an access request; in a second period of each time frame, performing an allocation period, during which the control node allocates transmission frames to all or part of the user nodes having transmitted an access request in the first period, each transmission frame allocated to a user being fragmented into a plurality of transmission intervals; and in a third period of each time frame, performing a transmission period, during which each user node allocated a transmission frame in the second period, transmits said voice packet in the allocated transmission frame thereof, transmission frames allocated to different users being interleaved within said transmission period so as to ensure simultaneous half-duplex communications of the different users.
