ENI#16 - Significant progress with approval of much of Release 2

The ENI#16 meeting on 7-10 December 2020 was "online only" due to travel restrictions or delegates not allowed to travel.

  • 29 delegates were registered and 29 were present
  • Operators were present from: China Telecom, China Mobile, Deutsche Telekom, NTT, Portugal Telecom, Telefonica and TIM
  • Government Ministry Institutes being members from Germany, China, Japan and South Korea
  • 163 documents were handled

The meeting was very productive and achieved significant progress. The work-items were progressed to stable output on the deliverables Draft GR ENI 008 on Intent Aware Network Autonomicity and Draft GR ENI 009 on Data Processing mechanisms both planned to be approved at the end of December. Approval as final draft on the evaluation of categories Draft GR ENI 010 describing measures of automation of the Classes published last year in GR ENI 007 v1.1.1.

Significant progress was made on the Policy Modelling for AI in ENI 005 work-item RGS/ENI-0016 aligned with MEF. An open area is approved for all stable drafts and previously published deliverables. The meeting approved and ratified the publication of the next versions on ENI use cases, and requirements version 3.1.1. Terminology for release 2 was progressed and a revised baseline approved. ENI 002 (ENI requirements) was published during the meeting as V3.1.1.

The meeting also worked on a Liaison with 3GPP SA5 and a separate Liaison with ISG NFV. These will be sent in January 2021. The Liaisons introduced ETSI ISG ENI’s work and asked for further collaboration highlighting ENI 001, ENI 005 and ENI 011. The meeting approved a new work-item on gap analysis for Intent policy management surveying the current and needed work.

In Progress work of ETSI ISG ENI in Release 2

The "Use Cases" ENI 001, "Requirements" ENI 002, "Terminology" ENI 004 and "System Architecture" ENI 005 are all open for the next release and work has started on each specification. A work-item on big data and its classification was approved to start ENI 009. The "AI Network Categorization" ENI 007 is published and a related report ENI 010 in the evaluation is progressing well.

Experiential Networked Intelligence (ENI) Release 2 specifications and reports are:

  • ENI 001 (WI RGS/ENI-0014) Use Cases under publication

  • ENI 004 (WI RGR/ENI-0018) Terminology
  • ENI 005 (WI RGS/ENI-0016) System Architecture
  • ENI 008 (WI DGR/ENI-0013) Intent Aware Network Autonomicity sent to stability review
  • ENI 009 (WI DGR/ENI-0017) Data Mechanisms sent to stability review
  • ENI 010 (WI DGR/ENI-0020) Evaluation of categories for AI application to Networks approved as final draft
  • ENI 011 (WI DGS/ENI-0021) Mapping between ENI architecture and operational systems
  • ENI 020 (WI DGR/ENI-0022) Reactive In-situ Flow Information Telemetry
