Abstract

L'invention propose un procédé de gestion de l'alternat pour une communicati on en mode semi-duplex entre au moins deux équipements d'extrémité (201-203) d' un réseau de transport à commutation de paquets en mode non connecté (300), dan s lequel un élément d'indication (M) a pour fonction, lorsqu'il est présent av ec une première valeur déterminée dans des paquets transmis depuis un (201) desdits équipements d'extrémité (201-203) vers un équipement central (400) assurant la gestion de la communication, d'indiquer audit équipement central (400), d'une part, que ledit équipement d'extrémité (201) accuse réception d u droit d'émettre qui lui est accordé par ledit équipement central (400) et, d'autre part, qu'il demande le maintien de ce droit d'émettre.
