(FR) SIM 4G COMPATIBLE AVEC UN SERVICE 5G
Abstract
(EN)
The methods, systems, and computer readable media discussed herein are directed to enabling a fifth generation cellular-wireless access technology (5G) user equipment (UE) to receive 5G service using a fourth generation cellular-wireless access technology (4G) subscriber identity module (SIM). Upon powering on, the 5G UE may determine whether a mobile network operator (MNO) public key file exists in the 4G SIM. Upon determining that the MNO public key file exists in the 4G SIM, the 5G UE may retrieve a MNO public key value from the MNO public key file, read a subscription permanent identifier (SUPI) from the 4G SIM, generate a subscription concealed identifier (SUCI) based on the SUPI and the MNO public key value, send the SUCI to a 5G mobile network for registering the 5G UE, and begin receiving 5G services from the 5G mobile network.

Les procédés, les systèmes et les supports lisibles par ordinateur décrits dans la présente invention concernent l'activation d'un équipement d'utilisateur (UE) de technologie d'accès sans fil cellulaire de cinquième génération (5G) pour qu'il reçoive un service 5G en utilisant un module d'identité d'abonné (SIM) de technologie d'accès sans fil cellulaire de quatrième génération (4G). Lors de la mise sous tension, l'UE 5G peut déterminer si un fichier de clé publique d'opérateur de réseau mobile (MNO) existe dans le SIM 4G. Lors de la détermination que le fichier de clé publique de MNO existe dans le SIM 4G, l'UE 5G peut récupérer une valeur de clé publique de MNO à partir du fichier de clé publique de MNO, lire un identifiant permanent d'abonnement (SUPI) à partir du SIM 4G, produire un identifiant caché d'abonnement (SUCI) en fonction du SUPI et de la valeur de clé publique de MNO, envoyer le SUCI à un réseau mobile 5G pour enregistrer l'UE 5G, et commencer à recevoir des services 5G provenant du réseau mobile 5G.
