Title (EN) SIGNAL MESSAGE COMPRESSION
(FR) COMPRESSION D'UN MESSAGE DE SIGNALISATION
Abstract:
(EN) A method for compressing a signalling message in a compressor in a communication system. The compressor comprising a compression memory, wherein the compression memory comprises a first memory in a virtual machine and a second memory external to the virtual machine. The method comprising the steps of : receiving a part of the signalling message (305); searching the second memory for a copy of the received part of the signalling message (309),- and determining a reference to the received part of the signalling message on the basis of the searching step; outputting the reference as a part of the compressed signalling message representing the received part of the signalling message (310).
(FR) L'invention concerne un procédé de compression d'un message de signalisation dans un compresseur d'un système de communication. Le compresseur comprend une mémoire de compression constituée d'une première mémoire présente dans une machine virtuelle et d'une seconde mémoire extérieure à la machine virtuelle. Le procédé consiste à: recevoir une partie du message de signalisation (305); interroger la seconde mémoire pour obtenir une copie de la partie reçue du message de signalisation (309), et déterminer une référence se rapportant à la partie reçue du message de signalisation consécutivement à l'étape d'interrogation; produire la référence en tant que partie du message de signalisation comprimé représentant la partie reçue du message de signalisation (310).
