Title
(EN) METHOD AND NODE FOR PERFORMING VOICE PACKET CLASSIFICATION IN A CELLULAR NETWORK
(FR) PROCÉDÉ ET NœUD POUR RÉALISATION D'UNE CLASSIFICATION DE PAQUET VOCAL DANS UN RÉSEAU CELLULAIRE
Abstract
(EN)
A method (200) for a node (105, 120; 200) for a cellular system (100), comprising making packet data transmissions to at least one other node (110, 120) and letting said packet data transmissions comprise at least two groups of data packets, speech packets and silence packets. The method comprises analyzing (205) data packets in order to determine a threshold value between said groups of data packets, and classifying (210) data packets as either speech packets or silence packets by means of the threshold value, and classifying (215) data packets of at least one of said groups into one of a number of sub-groups within its group. The method also comprises using (220) the sub-group of a data packet in order to determine an individual priority for a data packet, and using (225) said priority of a data packet when scheduling transmissions of the data packet.
(FR)
L'invention porte sur un procédé (200) pour un nœud (105, 120 ; 200) de système cellulaire (100), comprenant la réalisation d'une transmission de données par paquets à au moins un autre nœud (110, 120) et le fait de laisser lesdites transmissions de données par paquets comprendre au moins deux groupes de paquets de données, des paquets vocaux et des paquets de silence. Le procédé comprend l'analyse (205) des paquets de données afin de déterminer une valeur de seuil entre lesdits groupes de paquets de données et la classification (210) des paquets de données en tant que paquets vocaux ou paquets de silence au moyen de la valeur de seuil, et la classification (215) de paquets de données d'au moins l'un desdits groupes dans l'un d'un certain nombre de sous-groupes dans ce groupe. Le procédé comprend également l'utilisation (220) du sous-groupe d'un paquet de données afin de déterminer une priorité individuelle pour un paquet de données, et l'utilisation (225) de ladite priorité d'un paquet de données lors de la programmation de la transmission du paquet de données.
