Publication number: 20220046484Abstract: 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).Type: ApplicationFiled: September 26, 2018Publication date: February 10, 2022Inventors: Helen Örtenblad, Jan Backman, Göran Hall
