Abstract (en)

[origin: WO02080596A1] The invention concerns a method for managing two-way alternate communication in semi-duplex mode between at least two terminal facilities (201-203) of a packet switching transport network in non-connected mode (300), wherein an indicating element (M) serves, when it is present with a first specific value in the packets transmitted from one (201) of said terminal facilities (201-203) to a central facility (400) managing the communication, to indicate to said central facility (400) that said terminal facility (201) acknowledges receipt of the right to transmit which is granted to it by said central facility (400) and that it requests continuation of said right to transmit.
