Title: (DE) VERFAHREN ZUR PAKETVERMITTELTEN DATENÜBERTRAGUNG IN EINEM MOBILKOMMUNIKATIONSSYSTEM
(EN) METHOD FOR TRANSMITTING PACKET SWITCHED DATA IN A MOBILE COMMUNICATIONS SYSTEM
(FR) PROCEDE DE TRANSMISSION DE DONNEES A COMMUTATION PAR PAQUET DANS UN SYSTEME DE COMMUNICATION MOBILE
Abstract: front page image
(EN) The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver orders the desired transmission units. The transmitter sends transmission units according to the order. Ordering and transmission are repeated until the quality measured by the receiver from each packet exceeds the predetermined quality value and the data which is to be transmitted and consists of packets is transmitted from the transmitter to the receiver. The invention also relates to a mobile communications system implementing the method of the invention.
(FR) Cette invention se rapporte à un procédé de transmission de données à commutation par paquet dans un système de communication mobile mettant en oeuvre un protocole de demande de répétition automatique (ARQ). Selon ce procédé, le récepteur demande des unités de transmission désirées. L'émetteur envoie des unités de transmission correspondant à la demande. On répète les demandes et les émissions jusqu'à ce que la qualité mesurée par le récepteur à partir de chaque paquet excède la valeur de qualité préétablie et les données qui doivent être émises et sont constituées de paquets, sont émises par l'émetteur à destination du récepteur. Cette invention se rapporte aussi à un système de communications mobile mettant en oeuvre le procédé décrit ci-dessus.
