Data Path Diversity Support

Using the Control-User Plane Split (CUPS) feature, Open5GCore implements a large numbed of deployment scenarios for data path diversity:

The implemented functionality in the SMF and PGW-C enables the following scenarios:

  • Support for multiple APNs and dedicated bearers

  • Fast handover between Local Service Hosts (with and without IP address continuity)

  • Towards supporting Time Sensitive Networks (TSN):

  • Support for Ethernet bearers

  • Congestion triggered, network only data paths change

  • Data path offloading for specific bearers (when connected to specific gNBs)
