Abstract

Procédé et un dispositif de communication. Dans le procédé de communication, un premier dispositif détermine, selon une demande d'enregistrement auprès d'un réseau reçue, qu'un utilisateur de fusion 4G/5G demande de s'enregistrer auprès d'un réseau 5G pour la première fois, des premières informations sont envoyées à un BOSS qui est en communication avec des dispositifs de réseau 4G et des dispositifs de réseau 5G, de sorte que le BOSS puisse commander le premier dispositif selon les premières informations, et le premier dispositif obtient et stocke des données d'utilisateur de l'utilisateur de fusion 4G/5G dans le réseau 4G sur la base de la commande du BOSS, l'utilisateur de fusion 4G/5G étant un utilisateur 4G qui utilise un terminal prenant en charge la capacité de communication 5G. Selon le procédé, un procédé de migration en ligne de données d'utilisateur de l'utilisateur de fusion 4G/5G peut être réalisé, et des opérations manuelles peuvent être évitées, ce qui permet d'améliorer l'efficacité de migration.
