3GPP Standards on Edge Computing

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 first part write-up is available here. 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 webinar brought together top experts at the 3GPP plenary level, SA2 (Architecture) and SA6 (application enablement and critical communication applications) for a deep-dive into how 5G and related standards can help harmonise and enable technologies like edge computing and artificial intelligence to work together much more efficiently. 

The webinar was co-chaired by Georg Mayer, 3GPP SA Chairman and Stephanie Parker, Trust-IT and Vice-chair of the 5G-IA Pre-Standardisation WG with the John Favaro, Trust-IT and member of the 5G PPP Automotive Working Group. 

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.

This video embedded below is the recording of the webinar on edge computing held on Thursday 22 April 2021 part 2 - 3GPP Standards on Edge Computing as an educational deep dive to help industry verticals gain a better understanding of an evolving landscape. It gives key insights into 3GPP standardisation work on edge computing with an overview of the main activities taking place within SA (System Aspects and Architecture). Presentations and panel discussions zoom in on the network layer with SA2 Architecture and on the application layer for vertical enablement with SA6 Application Enablement and Critical Communication Applications. The panel discussion with SA TSG, SA2 and SA6 chairmen sheds light on the role of artificial intelligence from both the network and application perspectives, underscoring the vital importance of industry verticals in the standardisation process to meet their specific requirements in 3GPP as a truly global initiative.

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

Main Takeaways

  1. 5G will help technologies like edge computing and artificial intelligence to harmonise and enable them to work together much more efficiently.
  2. 3GPP Release 17 is foundational for edge computing but more will come in future releases given its importance in mobile communications and as we gradually move beyond 5G. The webinar was therefore a timely deep-dive into today's landscape. 
  3. Artificial Intelligence and edge computing can both serve as building blocks but in different ways: 
    • Network layer perspectives: AI can further optimise edge computing applications.
    • Application layer persepctives: Edge computing can be a building block for AI, e.g. offloading limited capabilities from the device to the network.
  4. Global initiatives like 3GPP can help reduce regional fragmentation, drive convergence and enable network-compliant rollouts that benefit the ecosystem around the world.
  5. As a global initiative, 3GPP is well placed to build on its strong relationships and collaborations with ETSI MEC and GSMA. 
  6. It is absolutely essential that industry verticals get involved in 3GPP working groups, which is where key activities take place and where their requirements should be channelled. It is also important that verticals understand how their seemingly specific requirements could be relevant to other sectors. Being part of 3GPP is a complex but highly rewarding experience. It does not need to be a life-long commitment.

Poll Findings - Participant Viewpoints

Do you participate in standardization on edge computing?

Interestingly most respondents do not take part in any standardisation initiatives. Hence the webinar series was an opportunity to highlight the many activities taking place and encourage participants to get involved. Those that do take part mostly contribute to 3GPP and other forums (29%) like ETSI (SDO) and industry associations like 5GAA and 5G-ACIA as some of the early movers on edge computing. Beyond 3GPP, a smaller number of respondents (11%) contribute to ETSI and other forums such as 5GAA and GSMA and the same amount (11%) are involved in other forums.

How important do you think coordination on edge computing standardisation is?

Coordination on edge computing standardisation needs to be prioritised with 65% of respondents saying it's vital and another 33% saying it's quite important. Only 1 respondent said it's not needed. An important output via the 5G-IA Pre-Standardisation WG and supported by panellists and organisers (5G-IA, 5GAA, 5G-ACIA and PSCE) would be a user-friendly guide on edge computing standardisation to help stakeholders navigate the landscape. 

Do you see a need for new areas of standardisation for edge computing?

Findings from this poll are particularly interesting as we have a close split between those that think more standardisation work is needed (47%) and those that don't know (43%) with just 10% saying it's not needed. Webinar organisers have come up with two possible explanations. On the one hand, we may be looking at a fragmented landscape that would benefit from more unification, also from an architecture perspective. On the other hand, organisations looking at the landscape may simply be overwhelmed by the dverse activities taking place. They may also have new applications sitting on top of the network but are not sure if they need to be standardised. Practical guidance could go a long way in clarifying this uncertainty. 

Again, a quick guide on edge computing standardisation could be a useful output, highlighting also the good cooperation already taking place as an important step in the right direction.
