Abstract
A mechanism is provided to ensure the same user plane anchor point is selected as a User Equipment (UE) moves across multiple access networks. The selected User Plane Function (UPF) identifier information, such as a Fully Qualified Domain Name (FQDN) is passed to the UE anchor points. This will allow the UE anchor points to exchange the already selected user plane information so that the new UE anchor point can choose the same UPF.
