Feature Description

The Converged Datapath feature allows interconnection of the same UE’s session at UPF instance with SGW-C/cnSGW and Session Management Function (SMF)/Inter-Working Function (IWF) to build converged/collapsed datapath and achieve higher throughput. With this feature:

  • The UP/UPF selection logic is enhanced to aid same node selection on SGW-C/cnSGW and SMF.

  • The SxDemux selects the same Session Manager (SessMgr) instance based on existing session of N4 or Sxa respectively.

  • The Sxa session and N4 session correlation is done at SessMgr.

  • The datapath is allowed to be collapsed in the forwarding plane.

  • Extra hop in subscriber’s datapath is eliminated, resulting in reduced latency and improved user experience.
