The invention is a system and method for synchronizing the transmission of compressed headers in data packets be-tween a transmitter and a receiver having a preferred wireless application which is an improvement of RFC2508. In a system having a transmitter transmitting a plurality of packets each containing a header to a receiver, a method of synchronizing the transmission of compressed headers between the transmitter and receiver in accordance with the invention includes transmitting a current packet from the transmitter to the receiver containing information that the transmitter is prepared to send subsequently transmitted packets in which the headers therein are to be compressed in comparison to the header contained in the current packet; and transmitting from the receiver to the transmitter an acknowledgment packet that the receiver has received the current packet.
L'invention concerne un système et un procédé servant à synchroniser la transmission d'en-têtes comprimés de paquets de données entre un émetteur et un récepteur équipés d'une application sans fil préférée qui constitue un perfectionnement de RFC2508. Dans un système comprenant un émetteur transmettant à un récepteur plusieurs paquets contenant chacun un en-tête, le procédé de synchronisation de transmission d'en-têtes comprimés entre l'émetteur et le récepteur comporte les étapes consistant à: transmettre un paquet en cours, de l'émetteur vers le récepteur, qui contient des informations selon lesquelles l'émetteur est préparé à envoyer ultérieurement des paquets contenant des en-têtes comprimés par rapport à l'en-tête du paquet en cours; et transmettre, du récepteur vers l'émetteur, un paquet d'accusé de réception confirmant que le récepteur a reçu le paquet en cours.
