5G-MAG tracks 3GPP Non-Public Network (NPN) standards for private 5G media production and contribution. For NPN deployment models, identity/onboarding and QoS considerations, see the Technology page.
5G-MAG tracks NPN standardisation as it applies to media production and contribution, in particular the VIAPA requirements, the SNPN and PNI-NPN deployment models, device onboarding at scale, and the combination of NPN with TSC for deterministic essence transport and with RTC for interactive contribution.
At a glance
- Deployment models: Standalone NPN (SNPN) and Public Network Integrated NPN (PNI-NPN), both defined in clause 5.30 of TS 23.501.
- By release: Release 16 is the baseline; Releases 17, 18 and 19 extend it; Release 20 has the study FS_PLMNNPN_Ph2 (TR 33.758) and PLMNNPN_Ph2-SEC (TS 33.501).
- Media focus: the VIAPA requirements, device onboarding at scale, and the combination of NPN with TSC and with RTC.

NPN deployment models
Both deployment models are defined in clause 5.30 of TS 23.501, Support for non-public networks (SNPN in clause 5.30.2 and PNI-NPN in clause 5.30.3).
- Standalone NPN (SNPN): Independent 5G network with its own core, not relying on a public land mobile network (PLMN). Identified by the combination of a PLMN ID and a Network Identifier (NID).
- Public Network Integrated NPN (PNI-NPN): NPN made available through a PLMN, for example by means of a dedicated Data Network Name (DNN) or one or more network slice instances allocated for the NPN, optionally using a Closed Access Group (CAG) to control which subscribers may access the relevant cells.
Release by release
The NPN feature set has grown across releases. The following is an orientation, not a substitute for the 3GPP work plan.
- Release 16: Baseline NPN. Introduced the SNPN and PNI-NPN models, the NID for SNPN, and the CAG mechanism for PNI-NPN (work items Vertical_LAN and, for the RAN, NG_RAN_PRN). Architecture in the NPN clause of TS 23.501.
- Release 17: SNPN enhancements (eNPN, NG_RAN_PRN_enh). Credentials Holder support (credentials owned by a separate 3GPP or non-3GPP entity such as an AAA server), UE onboarding and remote provisioning, IMS voice and emergency services and PWS for SNPN. Related VIAPA requirements work continued in TS 22.263.
- Release 18: Non-Public Networks Phase 2 (eNPN_Ph2). Mobility between equivalent SNPNs without new network selection, non-3GPP access for SNPN, and access to Localized Services.
- Release 19: security for a PLMN hosting an NPN (PLMNNPN, TS 33.501), interconnect of SNPNs (ISN, TS 22.261 and study TR 22.848), ProSe in NPN (TEI19_ProSe_NPN) and CAG-based access control for NR Femto (5G_Femto).
- Release 20: security for a PLMN hosting an NPN, phase 2: the study FS_PLMNNPN_Ph2 (TR 33.758) and PLMNNPN_Ph2-SEC (TS 33.501). No Release 20 description (TR 21.920) exists yet, so confirm Release 20 content against the current 3GPP work plan.
The per-release features and the clauses of TR 21.916 to TR 21.919 that describe them are on the Release history page.
