Edge Computing - Industry Vertical Viewpoints


A sub-set of 3GPP Market Representation Partners hosted a 2-part webinar series in April 2021 looking at edge computing for industry verticals and on-going standardisation work in 3GPP. The webinar was attended by a mix of organisations from both verticals and the telecommunication industry, helping to share a common understanding on edge computing. 

The first webinar brought together experts from the 5G Automotive Association (5GAA), the 5G Alliance for Connected Industry and Automation (5G-ACIA), Edge Gallery, ETSI Multi-access edge computing (MEC) and the Automotive Edge Computing Consortium (AECC) to highlight opportunities and updates on how diverse market sectors can benefit from offloading data at the edge of the network. Further insights came from interactive discussions and polling with participants. This webinar is part of a 5G user webinar and workshop series designed for industry verticals co-hosted by 5G-IA, 5GAA, 5G-ACIA and PSCE as Market Representation Partners of 3GPP.

This video embedded below is the recording of the webinar on Tuesday 20 April on edge computing - part one, giving an educational deep dive on industry vertical viewpoints. 5GAA (5G Automotive Association) gives an overview of its white paper, use cases and upcoming trials for Cellular-V2X in the automotive sector. Edge Gallery shows how it is supporting the Industrial Internet of Things with its 5G open-source solutions and application development support. ETSI MEC explain its common and extensible application enabling platform for new business opportunities. 5G-ACIA (5G Alliance for Connected Industry and Automation) describes new work on the applicability of 5G industrual edge computing within the associaton. The Automotive Edge Computing Consortium (AECC) brings insights into how it is driving data to the edge.

Bios and PDF presentations as follows:

Global5G has a summary with main takeaways and poll findings here. The following is from there:

Main takeaways

  1. The webinar was an excellent deep-dive into the edge computing landscape highlighting on-going work in automotive, manufacturing and the Industrial Internet of Things, as well as standardisation work in ETSI and open-source approaches. 
  2. It illustrated the value of edge computing with strong signs coming from industry in terms of growing interest and adoption roadmaps. There is an impressive number of initiatives across the globe embracing edge computing, with examples of cooperation globally as seen in 5GAA, 5G-ACIA, AECC and ETSI MEC. 
  3. Industrial automation, digital twins and infrastructure control among the main drivers for growing demand. 
  4. Collaboration on edge computing is essential and will become even more important as applications increasingly move to the edge. Continued discussions are needed to have greater clarity at multiple layers: business and technology, SW and HW. Collaboration can also support efforts to educate consumers and businesses, both key to uptake and achieving network compliant rollout.  
  5. The collaboration underpinning the 3GPP MRP webinar series is an excellent example of how we can intensify joint efforts across the ecosystem working towards convergence and ensuring RoI, e.g. for telecom investments. 

Poll Findings - Participant viewpoints

Where would you position your organisation in terms of implementing edge computing?

Only 16% of respondents already have a commercial strategy in place for edge computing while 26% are starting to develop one. Therefore 42% are expected to have one in short term. 30% are at early learning stage to understand market opportunities and 28% are exploring its potential. 

In which verticals do you expect the first implementations other than automotive?

The automotive sector is an early mover in edge computing, as testified by 5GAA and AECC presentations in the webinar with both having published studies and white papers. 5GAA is planning trials in 2021 in various locations globally so another webinar on this topic in 2022 would be helpful. After automotive, manufacturing is expected to be the next sector to implement edge, as testified by the 5G-ACIA presentation. All three associations are market representation partners of 3GPP, with 5GAA also contributing to standardisation work. In the 5G PPP, 5GCroCo (cross-border automotive use cases) has contributed to standardisation activities of both 5GAA and AECC. Gaming, AR/VR and media is the next sector expected to adopt edge computing. 

What are your top 2 priority requirements for edge computing? 

Low latency is the top requirement for most respondents (33%) followed by interoperability and service continuity (both on 20.5%) with transferring and processing large volumes of data and very high reliability in joint third place (both on 12.8%). It' will be important to see how many of these requirements feature in early deployments as not all of them will be there at first rollout. The poll also shows how requirements combine together, e.g. 2 priority requirements: Low latency + very high reliability; Interoperability + Service continuity; Interoperability + Low latency; 3 requirements: Interoperability + Service continuity + Transferring and processing large volumes of data and 4 requirements: Interoperability + Service continuity + Low latency + Transferring and processing large volumes of data. 

Part 2 of this webinar is available here.

Challenges and Future Perspectives of Industrial 5G

Andreas Mueller, Head of communication and network technology at Bosch Corporate Research and Chair of 5G ACIA recently spoke at 'What Next for Wireless Infrastructure Summit' by TelecomTV about Industrial 5G. The following is paraphrased from his presentation 'Industrial 5G: Remaining challenges and future perspectives' which is embedded below: 

5G has the potential to become the central nervous system of the factory of the future, enabling unprecedented levels of flexibility, efficiency, productivity and also ease of use.  At the same time it's also a very special application domain so in many cases there are very demanding QoS requirements. 

Industrial applications have multi-faceted requirements where one case may require very low latencies and high reliabilities for instance, while for others we may need very high data rates (for example HD cameras). There is no single use case with a single set of requirements but many different use cases with very diverse requirements which also have to be supported in many cases at the very same time. 

As we need only a local network with local connectivity, this performance is required only in a very controlled environment; inside a factory, inside a plant. This allows for specific optimizations and makes certain things easier but we also always have brownfields deployments in many cases that means we have to live what we have in place today so that's typically wired communication in some cases it's wi-fi and similar wireless solutions and we have to be able to smoothly integrate a 5G network into this existing infrastructure

The developments towards Industrial 5G started about three years ago i would say and in the meantime it really has become a hot topic everybody is talking about industrial 5G. It has become a focused topic in standardization in 3GPP and some key capabilities already have been standardized which have been briefly outlined in the presentation. 

Good progress has also been made in the ecosystem development so we've established the 5G Alliance for Connected Industries and Automation two and a half years ago which serves as a global forum for bringing all relevant stakeholders together and for driving industrial 5G and we have 76 members today which includes major players from the telco industry but also from the industrial domain and also of course some universities and so on. We have seen the advent of non-public networks (NPN) so for the first time it will be possible for a manufacturers to deploy and operate such non-public networks inside a factory which are to some extent decoupled from the public networks.

If we look at the standardization timeline this is what you get. The first version of 5G release 15 of 3GPP was approved mid last year and it still had a very strong focus on consumer application and enhanced mobile broadband. If you buy 5G today, this is what you get then. Release-16 has for the first time had a very strong focus on industrial applications this has been approved in June this year and it includes features like ultra reliable low latency communication, non-public networks, time-sensitive communication. It means support for time-sensitive networking 5G and also native layer 2 transport so that we don't necessarily need internet protocol but we can directly transmit ethernet frames over a 5G network which again is very important especially for the industrial domain.

Release 17 is currently underway and it will come along with several enhancements of these features. It also has a stronger focus on positioning which is again very important in manufacturing because knowing where things are is a very valuable information and it will be in this new transmission mode called NR RedCap which is somewhere somewhere in between this high-end mobile broadband mode and also this low-end a massive machine type communication and this might be especially suitable for industrial sensors for example and then of course the journey will continue with Release 18 which is still being defined but with a high probability i would say it will more focus on massive iot applications that means tiny little sensors for example which have to be connected using very low energy and low costs and not just the natural next step.

So many things have been done already towards supporting these industrial applications but if you look at factories today there are only very few of them which already make use of 5g and that's because there are still some challenges to be overcome some of them are listed here first of all having the features in the standard is nice but they also have to be implemented in the chipsets and infrastructure components and that still say test takes some time especially if we consider that really 16 is the first release which really has many of the features that make a difference to the industrial domain

Here is a list of the features that can be prioritised for future 5G releases or even for 6G. As Release-17 has just been delayed slightly, quite possible that some of the features expected in 5G may get pushed on to Beyond 5G and even 6G.

Here is the embedded talk

5G Private and Non-Public Network (NPN)


Private Networks have been around for a while and really took off after 4G was launched. This is due to the fact that the architecture was simplified due to the removal of CS core and also the advancements in silicon, storage, computation, etc. allowed creation of smaller and more efficient equipment that simplified private networks.

While private networks imply an isolated network for selected devices that are allowed to connect on to the network, Non-Public Networks are much broader in scope. Chief among them is the ability of certain devices to be capable of working on Private as well as Public Network or roaming between them.

I recently ran a workshop on 'Introduction to Private 4G & 5G Networks' with a well known Industry analyst Dean Bubley. One of the sections looked at the Network Architecture based on the 3GPP standards. This tutorial is a part of that particular section. Slides and video embedded below. There are also some interesting videos on YouTube that show how and why Private Networks are needed and some use cases. The playlist is embedded in the end.

Non-public networks (NPN) - Private Networks by another name


3GPP TS 22.261, Service requirements for the 5G system; Stage 1 gives a definition of non-public network which is simply defined as 'a network that is intended for non-public use'. Section 6.25 provides more info

Non-public networks are intended for the sole use of a private entity such as an enterprise, and may be deployed in a variety of configurations, utilising both virtual and physical elements. Specifically, they may be deployed as completely standalone networks, they may be hosted by a PLMN, or they may be offered as a slice of a PLMN.

In any of these deployment options, it is expected that unauthorised UEs, those that are not associated with the enterprise, will not attempt to access the non-public network, which could result in resources being used to reject that UE and thereby not be available for the UEs of the enterprise. It is also expected that UEs of the enterprise will not attempt to access a network they are not authorised to access. For example, some enterprise UEs may be restricted to only access the non-public network of the enterprise, even if PLMN coverage is available in the same geographic area. Other enterprise UEs may be able to access both a non-public network and a PLMN where specifically allowed.

The requirements section is interesting too:
  • The 5G system shall support non-public networks.
  • The 5G system shall support non-public networks that provide coverage within a specific geographic area.
  • The 5G system shall support both physical and virtual non-public networks. 
  • The 5G system shall support standalone operation of a non-public network, i.e. a non-public network may be able to operate without dependency on a PLMN.
  • Subject to an agreement between the operators and service providers, operator policies and the regional or national regulatory requirements, the 5G system shall support for non-public network subscribers:
    • access to subscribed PLMN services via the non-public network;
    • seamless service continuity for subscribed PLMN services between a non-public network and a PLMN;
    • access to selected non-public network services via a PLMN;
    • seamless service continuity for non-public network services between a non-public network and a PLMN.
  • A non-public network subscriber to access a PLMN service shall have a service subscription using 3GPP identifiers and credentials provided or accepted by a PLMN.
  • The 5G system shall support a mechanism for a UE to identify and select a non-public network.
    • NOTE: Different network selection mechanisms may be used for physical vs virtual non-public networks.
  • The 5G system shall support identifiers for a large number of non-public networks to minimize collision likelihood between assigned identifiers.
  • The 5G system shall support a mechanism to prevent a UE with a subscription to a non-public network from automatically selecting and attaching to a PLMN or non-public network it is not authorised to select.
  • The 5G system shall support a mechanism to prevent a UE with a subscription to a PLMN from automatically selecting and attaching to a non-public network it is not authorised to select. 
  • The 5G system shall support a change of host of a non-public network from one PLMN to another PLMN without changing the network selection information stored in the UEs of the non-public network.


5G ACIA (5G Alliance for Connected Industries and Automation), a Working Party of ZVEI (German Electrical and Electronic Manufacturers’ Association) published a White Paper on '5G Non-Public Networks for Industrial Scenarios'.

This paper describes four industrial (IIoT) deployment scenarios for 3GPP-defined 5G non-public networks. The paper also considers key aspects, in particular service attributes that can help to highlight the differences between these scenarios. In contrast to a network that offers mobile network services to the general public, a 5G non-public network (NPN, also sometimes called a private network) provides 5G network services to a clearly defined user organisation or group of organisations.

The PDF of the white paper is available here.
