Patent

CA 2435667

A device (10) is disclosed that uses an continuous analytical function (514) representing mapping data relating object voice connection measurements to likely user perception of the quality of a voice connection. The device (10) is compact and inexpensive. It can be implemented on a single integrated circuit (18), or on a single printed circuit board. CPU (30) processing time is significantly reduced. The device (10) obtains a real-time estimate of likely user perception of a given connection in terms of a user perception rating system (514). The device (10) is reprogrammable, enabling it to be updated as more accurate mapping data is obtained.

La présente invention concerne un dispositif (10) qui fait appel à une fonction d'analyse continue (514) représentant des données de mappage qui mettent en relation des mesures de liaison vocale objets avec la perception utilisateur probable de la qualité de la liaison vocale. Le dispositif de l'invention (10) est compact et peu coûteux, et il peut être mis en oeuvre sur un seul circuit intégré (18) ou sur une seule carte à circuit imprimé. L'invention permet de réduire de manière significative le temps de traitement de l'unité centrale (30). Le dispositif précité (10) permet d'obtenir une estimation en temps réel de la perception utilisateur probable d'une liaison donnée exprimée selon un système de cotation de perception utilisateur (514). Le dispositif de l'invention (10) est reprogrammable, ce qui permet de l'actualiser au fur et à mesure que des données de mappage plus précises sont obtenues.
