Title
(EN) METHOD AND FUNCTIONS FOR HANDLING A UE'S ACCESS TO A DN
(FR) PROCÉDÉ ET FONCTIONS POUR GÉRER L'ACCÈS D'UN ÉQUIPEMENT UTILISATEUR À UN DN
Abstract
(EN)
The embodiments herein relate to a method performed by a SMF (110) for handling a UEs (101) access to a DN (130) in a 5G communications system. The SMF (110) obtains at least one anycast address supported at a DN/I (130/I) which is accessible by the UE (101) from its location. The SMF (110) sends instructions to a UPF/c (105/c) to report usage of the at least one anycast address. The SMF (110) receives, from the UPF/c (105/c), information that usage of the anycast address has been detected. When usage of the anycast address has been detected, the SMF (110) determines that future usage of the anycast address should be routed to the DN/I (130/I) via the UPF/I (105/I).

La présente invention concerne, selon des modes de réalisation, un procédé mis en œuvre par un SMF (110) pour gérer l'accès d'équipements utilisateurs (UE) (101) à un DN (130). Le SMF (110) obtient au moins une adresse anycast prise en charge à un DN/I (130/I) qui est accessible par l'UE (101) à partir de son emplacement. Le SMF (110) envoie des instructions à un UPF/c (105/c) pour rapporter l'utilisation de ladite adresse anycast. Le SMF (110) reçoit, de l'UPF/c (105/c), des informations indiquant que l'utilisation de l'adresse anycast a été détectée. Lorsque l'utilisation de l'adresse anycast a été détectée, le SMF (110) détermine que l'utilisation future de l'adresse anycast doit être acheminée vers le DN/I (130/I) par l'intermédiaire de l'UPF/I (105/I).
