Abstract

La présente invention concerne un procédé et un appareil pour optimiser un débit binaire de communication. Ledit procédé comprend les opérations suivantes : un premier terminal envoie un premier message de mise à jour d'appel à un second terminal, ledit premier message de mise à jour d'appel comprenant une première liste de débits binaires, et ladite première liste de débits binaires comprenant des valeurs de débit binaire dans une première liste de débits binaires d'origine qui sont inférieures ou égales à une première bande passante de transmission telle que déterminée par le premier terminal selon la première liste de débits binaires d'origine et la première bande passante de transmission; le premier terminal reçoit un second message de mise à jour d'appel envoyé par le second terminal; le premier terminal détermine, selon une liste de débits binaires de communication, la valeur de débit binaire maximale dans la liste de débits binaires de communication comme étant un débit binaire de la communication de données entre le premier terminal et le second terminal. Au moyen de la présente invention, une valeur de débit binaire d'une communication de données peut être déterminée selon la qualité de signal de la communication de données courante, permettant ainsi d'éviter une interruption dans la transmission de données entre des terminaux et d'améliorer l'efficacité de communication de données pour les terminaux.
