3GPP TS 22.104 for Release 16 (V16.2.0) provides Stage 1 normative service requirements for 5G systems, in particular service requirements for cyber-physical control applications in vertical domains.

• Key definitions: Cyber-physical systems are defined as systems that include engineered, interecting networkd of physical and computational components. Control applications are defined as applications that control physical processes. 
• High-level requirements: Communication services supporty cyber-physical control applications need to be ultra-reliable. In some cases, end-to-end latency must be very low. For cyber-physical control applications, communication supports operation in diverse vertical industries, such as industrial automation and energy automation. 

Technical specification 22.104 (V16.2.0) describes aspects related to:

• End-to-end service performance requirements and network performance requires regarding these end-to-end service performance requirements.
• Support for LAN-type services specific to industrial/high-performance use cases. Related Ethernet functionalities include, for example, those in IEEE 802.1Qbv.

Related work and specifications for 3GPP Release 17: It is important to note that additional potential new requirements are under development also for Rel-17, including 3GPP TS 22.104 V17.0.0 (2019-06). At the time of publication on STANDICT.eu, Rel 16 TS V16.2.0 was under change control. 

3GPP TR 22.832 identifies further Stage 1 potential 5G service requirements for cyber-physical control applications in vertical domains. It describes specific use cases aimed at clarifying and motivating these additional service requirements for Release 17. With respect to the Rel-16 baseline, this Technical Report identifies more specific requirements or additional requirements for closely-related additional functionality to improve the applicability of 5G systems to vertical domains. 

Aspects addressed are:

• Industrial Ethernet integration, which includes time synchronisation, different time domains, integration scenarios, and support for time-sensitive networking (TSN).
• Non-public networks, non-public networks as private slices, and further implications on security for non-public networks (NPN).
• Network operation and Maintenance in 5G non-public networks for cyber-physical control applications in vertical domains.
• Enhanced QoS monitoring, communication service and networks diagnostics.
• Communication service interface between application and 5G systems, e.g. information to the network for setting up communication services for cyber-physical control applications and corresponding monitoring.
• Network performance requirements for cyber-physical control applications in vertical domains.
• Positioning with focus on the vertical dimension for Industrial IoT.
• Device-to-device/ProSe communication for cyber-physical applications in vertical domains.

The section on 'merged potential service requirements', e.g. industrial Ethernet integration; NPNs; network operations and maintenance; positioning and device to device/ProSe communication, also relates to the common requirements mapping driven by a sub-set of 3GPP Market Representation Partners, namely: 5G Infrastructure Association (5G-IA), 5G Automotive Association (5GAA), 5G-ACIA (Alliance for Connected Industry and Automation) and Public Safety Communications Europe (PSCE). This wrork is supported by H2020 project Global5G.org. 

This 3GPP work item under SA1 for Release 17 is aimed at identifying more specific 5G service requirements for cyber-physical control applications in vertical domains, 5G service requirements on enhancements for cyber-physical control applications in vertical domains, and new 5G service requirements for specific aspects with respect to the Rel-16 baseline. 

By specifying further cyberCAV Stage 1, the work focuses on:

• Industrial Ethernet integration, which includes time synchronisation, different time domains, integration scenarios, and support for time-sensitive networking(TSN).
• High-level requirements for network operation and maintenance in 5G non-public networks for cyber-physical control applications in vertical domains. 
• Positioning with a focus on vertical directions/dimensions for Industrial IoT. 

Work in eCAV may be updated to reflect further progress of FS_eCAV (TR 22.832; SP-190092), such as non-public network, further aspects of network operation and maintenance in 5G non-public networks, and network performance requirements descried in FS_eCAV.

• Related work: The work item is based on corresponding studies in Rel-17, especially FS_eCAV, and the assessment of respective mechanisms by individual members and relevant cyber-physical control and automation industry organisations, such as 5G-ACIA (Alliance for Connected Industry and Automation). 

An evolution of the overall 3GPP system is required to ensure competitiveness in a long-term time frame. 

This Technical Specification marks such an evolutionary path from 3GPP Release 8 through to Release 16. 

TS 22.278 V16.2.0, Service Requirements for the evolved packet system (EPS), compiles requirements to ensure EPS can cope with the rapid growth in IP data traffic and demanding requirements for new multimedia type applications in terms of performance and quality, delivered to the user, while at the same time enabling cost-effective deployment and operation. 

The Evolved Packet System is characterised by:

• Reduced latency.
• Higher user data rates equating to broadband performance.
• Improved system capacity and coverage.
• Lower operational costs.

The TS describes high-level requirements in terms of user and operational aspects; basic capabilities; multi-access and seamless mobility; performance requirements for EPS; security and privacy; charging aspects.

5G brings the need to support different kinds of UEs (e.g., for the Internet of Things (IoT), services, and technologies is driving the technology revolution to a high-performance and highly efficient 3GPP system. The drivers include IoT, Virtual Reality (VR), industrial control, ubiquitous on-demand coverage, as well as the opportunity to meet customized market needs. These drivers require enhancements to the devices, services, and technologies well established by 3GPP. The key objective with the 5G system is to be able to support new deployment scenarios across diverse market segments.

• Technical Report Focus

TR 22.261 compiles requirements that define a 5G system. The 5G system is characterised, for example, by:

• Support for multiple access technologies.
• Scalable and customizable network.
• Advanced Key Performance Indicators (KPIs) (e.g., availability, latency, reliability, user experienced data rates, area traffic capacity).
• Flexibility and programmability (e.g., network slicing, diverse mobility management, Network Function Virtualization).
• Resource efficiency (both user plane and control plane).
• Seamless mobility in densely populated and heterogeneous environment.

The goal of this SA1 work item is to develop Stage 1 normative service requirements for multi-hop relay by enhancing the work done for “Indirect 3GPP Communication” in TS 22.278. 

This work will consider the potential requirements and KPIs in different domains (e.g. inHome, Smart Cities, Smart Farming, Smart Factories, Smart Energy, Public Safety, Logistics) identified and concluded in TR 22.866 and use them as the basis for developing stage 1 normative requirements. 

This work item aims to update TS 22.261 to include multi-hop support for UE-to-Network Relay UEs regarding the following aspects:

• General aspects.
• Permissions and authorization.
• Relay selection.
• Relays for IoT.
• Service continuity.
• Functionality Exposure to 3rd parties.
• Traffic scenarios.

Scenarios where the remote UEs and those UE-to-Network relay UEs in proximity to the remote UE are out-of-coverage are also in scope of this WI. Special attention to national regional regulatory requirements (e.g. emergency calls) shall be paid.

• Gap filling and evolutions:

While some verticals are already covered in earlier generations of mobile networks, others are new, each bringing their own set of requirements. However, one common requirement is better energy efficiency and more extensive coverage compared with what 3G and 4G can provide. Release 16 service requirements already include the possibility of having direct 3GPP communication or indirect 3GPP communication with the use of relays. Nevertheless, this may not be enough for the needs of the possible use cases from the area listed. Incorporating multihop relays into 5G will help to improve the energy efficiency and the coverage of the 5G system.

SCOPE: The present document defines the Stage 2 system architecture for the 5G System. The 5G System provides data connectivity and services. This specification covers both roaming and non-roaming scenarios in all aspects, including interworking between 5GS and EPS, mobility within 5GS, QoS, policy control and charging, authentication and in general 5G System wide features e.g. SMS, Location Services, Emergency Services.

Business role models in 2G, 3G and 4G have centred on relationships between MNO (mobile and network operators) and subscribers and between MNOs, e.g. roaming, RAN sharing.

5G is bringing about the shift towards enterprise business role models, with MNOs providing a network or network resources for use in enterprise. Depending on the degrees of ownership and management in enterprise, trust relationships are bringing additional requirements on the 5G system.

The focus of Business Role Models for Network Slicing (BRMNS) is on normative requirements that enable the 3GPP system to adequately support diverse business role models for network slicing by drawing on TR 22.830, which studies several use cases and their potential requirements.

Key objectives include:

• Additional control to 3rd parties.
• Security relationships.
• Constraints on network slice operation to better serve business needs.
• Non-public network access to MNO spectrum.

BRMNS (SP-180773; UI: 180015) is a completed 3GPP SA1 (services) for Release 16 (Q1-2 2020).
