A method for exchanging compression/decompression dictionaries, and a communications node, which comprises a client module issuing and receiving messages, a compression/decompression module for compression/decompression of messages issued and received by the client module, a first dictionary for use by the compression/decompression module, and a second dictionary for use by the compression/decompression module. When the client module determines a sequence based on which to exchange dictionaries with one or more peers (e.g. a P-CSCF), it creates the first dictionary comprising at least one prioritised type of message and sends the first dictionary to the compression/decompression module, which stores the first dictionary and further sends it to at least the peer node. Still based on said determined sequence, the client module further creates the second dictionary comprising at least one other type of message, sends the second dictionary to the compression/decompression module which stores it and further sends to a peer node.
L'invention concerne un procédé pour échanger des dictionnaires de compression/décompression, et un nAEud de communication, qui comprend un module client émettant et recevant des messages, un module de compression/décompression pour la compression/décompression de messages émis et reçus par le module client, un premier dictionnaire à utiliser par le module de compression/décompression, et un second dictionnaire à utiliser par le module de compression/décompression. Lorsque le module client détermine une séquence sur laquelle est basé l'échange de dictionnaires avec un ou plusieurs homologues (par exemple un P-CSCF), il crée le premier dictionnaire comprenant au moins un type de message de priorité et envoie le premier dictionnaire au module de compression/décompression, qui stocke le premier dictionnaire et l'envoie en outre au moins au nAEud d'homologue. En se basant toujours sur ladite séquence déterminée, le module client crée en outre le second dictionnaire comprenant au moins un autre type de message, envoie le second dictionnaire au module de compression/décompression qui le stocke et l'envoie ensuite à un nAEud d'homologue.
