Abstract

La présente demande concerne un procédé d'interruption d'appel dans un réseau ad hoc à bande étroite et un appareil associé. Le procédé comprend les étapes suivantes : durant le processus de lancement d'un appel vocal, le rejet, par un terminal de transmission, d'une voix inactive partielle d'une voix à envoyer ; le recodage de la voix, qui doit être envoyée, de la voix inactive partielle rejetée de façon à obtenir une trame de voix à envoyer ; l'incorporation d'informations d'indication prédéfinies dans une trame de voix cible à envoyer ; et à un emplacement de trame prédéfini, après qu'un canal de transmission a envoyé la trame de voix cible, qui doit être envoyée et dans laquelle sont incorporées les informations d'indication prédéfinies, le canal de transmission commute pour réaliser une réception. Lorsque la trame de voix dans laquelle sont incorporées les informations d'indication prédéfinies est reçue, s'il n'y a pas de demande d'interruption en provenance d'un terminal d'interruption, une station de base envoie la trame de voix via un canal de transmission, et à un emplacement de trame prédéfini après que le canal de transmission a envoyé la trame de voix, le canal de transmission commute pour réaliser une réception de façon à recevoir la demande d'interruption, et si la demande d'interruption envoyée par le terminal d'interruption est reçue, la demande d'interruption est envoyée au terminal de transmission de sorte que le terminal de transmission met fin à l'appel vocal, ce qui résout le problème de faible souplesse d'interruption d'un appel.
