Abstract

Les modes de réalisation de la présente divulgation se rapportent au domaine technique des communications mobiles. La divulgation concerne un procédé de communication TDLS, un dispositif électronique et un support de stockage. Le procédé de communication TDLS est appliqué à un premier dispositif de station (STA), et le procédé comprend les étapes consistant à : déterminer une première trame radio, la première trame radio contenant un premier identifiant, et le premier identifiant donnant l'instruction à la première STA de transmettre un service à faible latence et indiquant un canal d'établissement de liaison directe en tunnel (TDLS) ou un canal TDLS hors canal étendu correspondant à un identifiant de trafic (TID) du service à faible latence ; et envoyer la première trame radio de façon à donner l'instruction à un dispositif de point d'accès de lancer une diffusion, selon le premier identifiant, que la première STA transmet le service à faible latence dans le canal TDLS ou le canal TDLS hors canal. Des modes de réalisation de la présente divulgation concernent en outre un mode de transmission d'un service à faible latence au moyen d'un mécanisme TDLS.
