Summary

Recommendation ITU-T Y.3128 specifies requirements for network function communication between public networks (PNs) and public network integrated non-public networks (NPNs) in IMT‑2020. These requirements build on the analysis of relevant use cases and related network problems.

There are two types of NPN: public network integrated non-public networks (PNI-NPN); and stand-alone non-public networks (SNPN). The requirements specified in this Recommendation concern the first type.
