*November 1, 2018: 3GPP and its Japanese Organizational Partners: The Telecommunication Technology Committee (TTC) and Association of Radio Industries and Businesses (ARIB) have hosted a “3GPP Summit” Conference Session at CEATEC JAPAN 2018, one of Japan’s largest ICT Conference and Exhibitions (https://www.ceatec.com/en/), on 17th October, 2018 in Makuhari area, Chiba-Pref., Japan.

This event was co-located with the “5G International Workshop” hosted by Japanese Ministry of Internal Affairs and Communications (MIC) and 5G Mobile Communications Promotion Forum (5GMF), in the same room that afternoon.

The “3GPP Summit” featured all three Technical Specification Group (TSG) Chairman (CT, RAN, SA) alongside their Japanese Vice Chairman, all joined by the Chairman of the 3GPP Security group (SA3) and the 5G Automotive Association (5GAA) – a Partner in 3GPP – who were also presenting. The 3GPP technical leadership event attracted an audience of around 700 people, which was in excess of the full seating capacity of the largest conference room in the Makuhari Messe expo center (https://www.m-messe.co.jp/en/) – So it was standing room only!

The session kicked-off with Opening Remarks by Shuichi Inada, Secretary General of TTC, the serving 3GPP Project Coordination Group (PCG) Vice-Chair. His remarks included the assertion that 3GPP standardization is the leading focal point in the emergence of 5G.

The ETSI CTO and the Head of 3GPP Mobile Competence Centre (MCC), Adrian Scrase presented on the 3GPP concept for the standardization, global collaboration and overall technical trends from 3G, via 4G through 5G.

The session then heard presentations from each of the TSGs, with each group being represented by the Chairman and one of the Vice Chairman from a Japanese Member company – each presentation being partially conducted in English and then in Japanese, with translation available for each.

Balazs Bertenyi and Satoshi Nagata of TSG-RAN showed the 5G concept for “5G-NR” with an explanation of the so-called “Non-Standalone” option for coordination with 4G based systems and the “Standalone” NR - with whole 5G components. They then introduced the current work items towards 3GPP Release 16 and their standardization schedule.

Erik Guttman and Yusuke Nakano of TSG-SA elaborated the 5G system architecture and configurations derived from well-deliberated examples of use cases around 5G’s three major requirements, for “eMBB”, “mMTC” and “URLCC”.

Georg Mayer and Atsushi Minokuchi of TSG-CT focused on the major technical transformation of Core Networks, namely “softwarization” and “Service based architecture”, explaining the main enablers for them.

Following the 5G overall technical specifications and services, the focus moves on to security aspects. Anand R. Prasad, the Security WG, SA3 Chairman presented 3GPP progress on security for the new requirements and architecture demands of 5G.
