Study on enhanced support of Non-Public Networks (NPN)
3GPP Rel-16 added 5GS support for Non-Public Networks based on stage 1 service requirements in TS 22.261 [2]. The scope of this Technical Report is to study further enhancements to the 5GS to fulfil the not yet supported stage 1 service requirements for Non-Public Networks in TS 22.261 [2] and requirements described in e.g. TS 22.263 [3].
The following aspects are in scope of the study:
1. Study enhancements to enable support for SNPN along with subscription / credentials owned by an entity separate from the SNPN.
2. Study how to support UE onboarding and provisioning for non-public networks.
3. Study enhancements to the 5GS for NPN to support service requirements for production of audio-visual content and services e.g. for service continuity.
4. Study the possibility for customizations or optimizations of 5GS when used for NPN considering different deployment scenarios, e.g. when the NPN is deployed and managed with the support of PLMN, when the NPN is deployed for different coverage and device density.
5. Study the need for additional exposure capabilities due to support for NPN.
6. Study support for SNPN and PLMN sharing the same NG-RAN, if anything missing from Rel-16.
7. Study support for voice/IMS emergency services for SNPN.
