Abstract

L'invention porte sur des systèmes et des méthodes permettant de traiter des messages codés dans des systèmes de télécommunications sans fil. Un serveur du système de télécommunications sans fil détermine si la taille du message codé est trop volumineuse pour un appareil de télécommunications sans fil. Si le message est trop volumineux, le serveur supprime une portion du message et envoie un message abrégé à l'appareil sans fil, accompagné de renseignements supplémentaires concernant le traitement du message codé, par exemple, les valeurs de hachage du contexte, qui aident l'appareil de télécommunications sans fil à vérifier le message abrégé.
