• 5G-ACIA was established to serve as the central
and global forum for addressing, discussing, and
evaluating relevant technical, regulatory, and
business aspects with respect to 5G for the
industrial domain.
• The main objective of 5G-ACIA is to ensure the
best possible applicability of 5G technology and 5G
networks to the industrial domain.
• 5G-ACIA’s mission is to make sure the interests
and needs of the industrial domain are adequately
considered in 5G standardization and
regulation and that ongoing 5G developments are
understood by and effectively transferred to the
industrial domain.

approved in 2021 Jan. Plenary
Status: approved in Plenary meeting, Junuary 2021

Rapporteur: Verizon (Rashmitha Sirsi)
Start-End dates: 02.2021 – 09.2021
Objectives: One of the objectives of this WI is to analyze factory floor edge computing use cases for
different non-public network configurations. The other objective is to identify application requirements for
use cases that require extra fast processing, very low latency, localized data, and data offloading for critical
operations. The advantages of edge computing (e.g. savings on bandwidth, improved reliability, security,
reduced latency) will be described and identified with key parameters whenever applicable. When possible,
the expected improvement of the key parameters to edge computing will be indicated. The benefits and
improvement will compare with Edge computing support and without it.
Deliverables:
• A report and input to WG3 (Industrial 5G Edge Architecture and deployment models) on edge cloud use
cases, requirements regarding manufacturing and process industries. This report will provide input to
WG3 Edge Cloud WI XX (anticipated new work-item from WG3 as per plan).
• Whitepaper on Industrial 5G Edge use cases and requirements (optional)
• Gaps between requirements published by other organizations and the requirements identified by this WI
will be communicated via LS to the relevant SDO groups (3GPP, ETSI MEC, etc.).
Basic steps:
• Identification of use cases that potentially
benefit from edge computing
> 3GPP UCs
> 5G-ACIA UCs
> New UCs from OT companies
• Edge benefit analysis for selected UCs
> Requirements for selected UCs
> Evaluation of edge computing benefits to meet the
requirements
• Impact of edge location options on edge benefit
analysis
> Public Network Domain
- a) Edge @ Core Network; b) Edge@ Transport
Network; c) Edge@ Access Network
> Non-Public Network Domain
- Edge @ IT enterprise domain; b) Edge@ OT
production domain
Basic steps of study “Industrial 5G Edge computing use cases and requirements”
New UCs from OT companies are being defined
Example of basic steps of benefit analysis for Mobile Robot use case
Example for Mobile Robot UC:
Step 1: Description - Mobile robots perform activities like
assistance in work steps and transport of goods,
materials and other objects. They are controlled by a
Guidance Control System (GCS)
Assumption – GCS is hosted in the edge
Step 2: E2E latency – 3GPP TS 22.104: 10 ms - 100 ms
….
Step 3: Local data processing - GCS hosted in the edge
processes locally images/video received by the GCS
from cameras of robots and control data
received from sensors of robots (e.g. in a local GW)
…
Step 4: Edge benefit - no need to send images/video/control
information deeply to the core network towards
central cloud system to process it there. This means
a shorter roundtrip end-to-end latency for
communications between the GCS and mobile
robot(s) i.e. reduced E2E latency
3GPP TS 22.104 requirements:
Integrated edge deployment in 5G network
Source: ETSI MEC
Different deployment options for edge location (I)
• Public network domain
a) Core Network
b) Transport Network
c) Access Network
• Non-Public Network domain
a) IT enterprise domain
b) OT production domain
General assumptions:
• Client application X, running in a Sensors/Actuators (S/A) or in
Controllers/Main (C/M) needs to connect to Edge App X (Server
App X) running in a Edge platform.
• Edge App X can be used as a middleman between different S/As
or C/Ms (wireless or wired) to exchange application related
information between them.
• The Edge platform can belong to either a 3GPP Mobile Network
Operator (MNO), OT company or a 3rd party.
• All required business agreements are in place between the
involved parties in order to allow the S/A or C/M to access the
requested edge apps located in the related edge platform.
• Controllers/Main (C/M),
• Sensors/Actuators (S/A)
Wireless S/A
Wired S/A

• 5G-ACIA has a specific strategical goal on edge computing
• Within scope of this goal the new study on industrial edge
computing use cases and requirements has started in February
> the objective is to select those industrial use cases for which
edge computing are relevant and evaluate edge benefits for
these use cases
• Outcome of this study on use cases is considered as an input to
initiate a new study on industrial 5G edge computing
architecture to complete the strategical goal.
• As a result of the two studies it is expected to impact to the
3GPP and ETSI standardization bodies.
