Abstract

La présente invention concerne un procédé et un terminal de commande d'appel chiffré. Le procédé de commande d'appel chiffré comprend les étapes suivantes : dans un processus d'appel chiffré, la réception d'une instruction de commande d'appel chiffré ; et selon l'instruction de commande d'appel chiffré, l'envoi d'une demande de traitement d'appel chiffrée correspondant à un terminal récepteur dans l'appel chiffré, de telle sorte que le terminal récepteur détermine, selon la demande de traitement d'appel chiffré, s'il faut déchiffrer un flux vocal ultérieur. Au moyen de la solution technique de la présente invention, la situation dans laquelle un terminal récepteur déchiffre incorrectement un flux vocal provenant d'un réseau est évitée lors du processus d'attente de l'appel chiffré, ce qui permet d'éviter les bruits générés en raison du déchiffrement incorrect, et d'améliorer l'expérience de l'utilisateur pendant la mise en attente de l'appel dans l'appel chiffré.
