Abstract
The present disclosure relates to method performed by a control node (SMF) configured to configure data sessions for a user equipment, UE, wherein at least one first data session is established by a first User Plane Function, UPF, node (UPF) and the first data session (DS) is connected via a first wireless access node (gNB_Source) associated to a first geographical area (UPF_area) of the first UPF node (UPF), the method comprising receiving, from a service node (NWDAF), a first notification () of predicted geographical area mobility of the UE, the first notification () being directly or indirectly indicative of a plurality of predicted target wireless access nodes (WN, WN) indicated as potential target access nodes for the UE, processing the first notification (), and determining if connecting the UE to any one of the plurality of predicted target wireless access nodes (WN, WN) comprises a change to an associated geographical area (UPF_area) different to the first geographical area (UPF_area), transmitting, to the first wireless access node (gNB_Source), a data session modification request () comprising the processed first notification, the data session modification request being indicative of a request to transfer the at least one first data session (DS) to any one of the plurality of predicted target wireless access nodes (WN, WN), receiving, from the first wireless access node (gNB_Source), a data session establishment response () comprising a selected wireless access node (gNB_Target) of the plurality of predicted target wireless access nodes, the selected wireless access node (gNB_Target) being associated to a second geographical area (UPF_area), configuring at least one second data session (DS), to be connected via the selected wireless access node (gNB_Target), by sending, to a second User Plane Function, UPF node (UPF) serving the second geographical area (UPF_area), a data session establishment request (), receiving, from the selected wireless access node (gNB_Target), a second notification () indicative of a transfer of the UE from the first wireless access node (gNB_Source) to the selected wireless access node (gNB_Target), and releasing () the first data session (DS).
