Abstract: La présente invention concerne un procédé de traitement de paquets de données. Avant d'effectuer une compression d'en-tête sur des paquets de données reçus, une extrémité de réception obtient un numéro de séquence PDCP d'un paquet de données devant d'abord faire l'objet d'une décompression d'en-tête parmi les paquets de données envoyés par une extrémité d'envoi. Ainsi est-il possible d'éviter des erreurs dues à l'exécution d'une décompression d'en-tête sur les paquets de données par l'extrémité de réception lorsque les paquets de données sont dans le désordre, ce qui permet de réduire le taux d'erreur de décompression d'en-tête.

Abstract: Lorsqu'un équipement utilisateur (EU) est en mode non autonome (NSA), il peut être en communication avec des nœuds de réseau de différentes technologies d'accès radio (RAT). Par exemple, l'EU peut être en communication avec une cellule LTE 4G (par exemple, un eNodeB) et une cellule NR 5G (par exemple, un gNodeB). Mais l'EU peut perdre un service de NR lorsqu'il pénètre dans un espace où les signaux sont atténués (par exemple, un ascenseur). Sont ici divulguées des techniques pour rétablir rapidement un service de NR lorsque l'EU sort de l'espace à signal atténué.

Abstract: The present invention relates to an ultra-light three-dimensional multi-stage porous cerium dioxide material and a preparation method therefor, comprising the following steps: respectively dissolving cerium salt and a molecular foaming agent and mixing to obtain a precursor solution; drying the precursor solution, and heat-treating the dried product at 400-1000°C for 0.5-4.0 h to obtain the ultra-light three-dimensional multi-stage porous cerium dioxide material. The ultra-light three-dimensional multi-stage porous cerium dioxide provided in the present invention has through-connected macroporous-mesoporous-microporous multi-stage pore channels, good crystallinity, high porosity and large specific surface area, aerogel-like ultra-light properties and good thermal stability, and the preparation process is simple, rapid, easy to operate, suitable for macro-scale preparation, economical and environmentally friendly.
