How it Works

The functionality of Multiple cnSGW feature involves:

  • Single UPF has multiple N4/Sx interface associations with SMF/cnSGWs.

  • There's no slicing of configuration in UPF per individual SMF.

  • Cumulatively, a maximum of four peers—combination of cnSGW/SMF or individual cnSGW/SMF as per the need—are connected to a single UPF.

  • Individual N4/Sx association release purges sessions of the impacted peer.

  • UPF redundancy works seamlessly.

  • All cnSGWs paired with a UPF is associated with a single user plane service.
