Abstract[English]
A method performed by a user equipment (UE) is provided. The method includes receiving a non-access stratum (NAS) container for the UE at a UE NAS routing layer. The UE includes UE NAS modules associated with NAS connections terminated at respective network functions in a serving network. The NAS container contains payload information that is ciphered and integrity protected, and routing information that is integrity protected only, and the routing information indicates a NAS type of a respective UE NAS module of the UE NAS modules. The method includes reading the routing information that indicates the NAS type to determine the respective UE NAS module, and routing the NAS container to the respective UE NAS module based on the routing information.[French]
Un procédé exécuté par un équipement utilisateur (UE) est décrit. Le procédé consiste à recevoir un conteneur de strate de non-accès (NAS) pour l'UE au niveau d'une couche de routage NAS d'UE. L'UE comprend des modules NAS d'UE associés à des connexions NAS terminées au niveau de fonctions de réseau respectives dans un réseau de desserte. Le conteneur NAS contient des informations de charge utile qui sont chiffrées et protégées par intégrité, et des informations de routage qui sont protégées en intégrité uniquement, et les informations de routage indiquent un type NAS d'un module NAS d'UE respectif parmi les modules NAS d'UE. Le procédé comprend la lecture des informations de routage qui indiquent le type de NAS pour déterminer le module NAS d'UE respectif, et le routage du conteneur NAS vers le module NAS d'UE respectif sur la base des informations de routage.
