TR 23.726 (SA2)
Study on Enhancing Topology of SMF and UPF in 5G Networks

Rapporteur:  Mr. Thiebaut, Laurent

The objective of this Technical Report is to study enhancements of 5GS architecture that has been defined in Rel-15 about the topology of SMF and UPF, and:
  1. investigate mechanisms to enable the 3GPP system to support deployments where a SMF is not able / allowed to control UPF(s) throughout the same PLMN.
  2. Study whether it is needed to enhance the capability of 5GS architecture for a UPF to be controlled by multiple SMF's (and many UPF's to be controlled by many SMFs) and, if yes, define such enhancements.
For these objectives, use cases will be defined.
