The objective and scope of this TR is to study enhancements to 5GS that are required to fulfil Stage-1 service requirements in vertical domains defined in TS 22.261 and TS 22.104:
Enablers (e.g. time synchronization of packet delivery in each hop) to support Time Sensitive Networking, and industrial control use cases specified by Stage 1.
Architecture enhancements required to support security requirements.
Enhancements to the 5G system to support 5GLAN service.
Enhancements to service exposure via APIs for 3rd party use of functionalities e.g. for information regarding the geographic location of coverage area of non-public network;
Enablers to support new KPIs (e.g. 5QI) to meet service requirements of vertical;
Support for non-public networks:
Support for UEs being registered in non-public network and a PLMN when the UE supports credentials required for non-public network and credentials required for a PLMN and is able to maintain both registrations independently.
Support for roaming, mobility and service continuity between PLMN and non-public networks (e.g. for mobility from non-public networks to PLMN) with direct interaction between non-publicnetworks and PLMN.
