Patent

CA 2302279

A method and system for controlling speech encoding in a communication system utilizes feedback information such as packet modification control data (154) sent from a communication link output controller, such as a network arbitor (142). The network arbitor (142) sends the packet modification control data (154) to a selected vocoder (146) to change the filter states of the selected vocoder (146) when the network arbitor (142) modifies an output speech packet communicated of a communication link (20), to facilitate improved convergence of a speech encoder and a speech decoder, such as a mobile subscriber unit.

L'invention concerne un procédé et un système de commande du codage vocal dans un système de télécommunication qui utilise des informations par rétroaction telles que des données (154) de commande de modification de paquet envoyées à partir d'un contrôleur de sortie de liaison, tel qu'un arbitre de réseau (142). Ce dernier (142) envoie les données (154) de commande de modification de paquets à un vocodeur sélectionné (146) de manière à modifier les états de filtres du vocodeur sélectionné (146) lorsque l'arbitre de réseau (142) modifie un paquet phonie de sortie d'une liaison (20), de manière à faciliter une convergence améliorée d'un codeur vocal et d'un décodeur vocal, tels qu'une unité d'abonné mobile.
