Feature Description

SMF supports IP pool allocation per slice with the same DNN. A slice is a logical end-to-end network that is created dynamically. A user equipent (UE) can access multiple slices over one access network, such as over the same radio interface.

For this feature, SMF performs the following tasks:

  • Register, discover, subscribe, and send traffic to all the external NFs based on the slice ID.

  • Provide slice-based procedure and session statistics.

  • Provide slice information on an EDR.

  • Provide slice information on logs.

  • Limit the maximum number of supported slices on SMF to 512.
