Abstract

Des modes de réalisation de la présente invention sont destinés à être utilisés pour maintenir une communication de données ininterrompue dans un système de communication de réseau privé à semi-duplex. La présente invention concerne un procédé de communication à semi-duplex, un terminal et une station de transmission. Le procédé des modes de réalisation de la présente invention comprend les étapes suivantes : un terminal reçoit une instruction d'attribution de canal transmise par une station de transmission, l'instruction d'attribution de canal étant utilisée pour indiquer un canal vocal à semi-duplex et un canal de données attribués au terminal, le terminal effectue un appel vocal à semi-duplex par l'intermédiaire du canal vocal à semi-duplex et transmet des premières données d'application et un identifiant de terminal du terminal à la station de transmission par l'intermédiaire du canal de données, l'identifiant de terminal étant utilisé pour permettre à la station de transmission d'associer le canal de données avec le terminal, et le terminal reçoit, par l'intermédiaire du canal de données, des secondes données d'application transmises par le système. En raison du fait que le terminal transmet son propre identifiant de terminal à la station de transmission, la station d'émission associe le canal de données avec le terminal, et des données peuvent ensuite être transmises au terminal par l'intermédiaire du canal de données, et une communication de données ininterrompue peut être maintenue dans le système de communication de réseau privé à semi-duplex.
