1. TTC’s hot standardization topics 5G IoT/M2M All IP Interconnection Agenda 1. TTC’s hot standardization topics 5G IoT/M2M All IP Interconnection 2. TTC’s challenge Supplementary slides

IMT-2020 / 5G Started an initial study of IMT-2020/5G networking (Sept 2014 - March 2015) and developed White Paper on 5G networking (non-radio aspects): http://www.ttc.or.jp/e/topics/20150413/download The second phase of the study was completed in September 2015, which identified key networking study issues such as network softwarization, mobile front/back-haul networks, mobile edge computing. Series of 5G/IMT-2020 enlightening workshop were held from November 2016 to May 2017 (supplementary slide 1) Support 5GMF (the Fifth Generation Mobile Communications Promotion Forum) in Japan with keeping close collaboration with ARIB: http://5gmf.jp/en/

IMT-2020 / 5G TTC’s 5G Standardization Coordination Adhoc comprised of Network Vision WG, 3GPP WG, Mobile Network Management WG, Access Network WG and Transport Network & EMC WG holds joint meetings regularly to confirm the strategic direction of ITU-T and 3GPP and to avoid duplication of the works. 5G study results have been submitted as input contributions to the following organizations: 3GPP, ITU-T SG13 WP1, Network softwarization including SDN, network slicing and orchestration (supplementary slide 2), ITU-T SG15 WP3, Technical report on Transport network support of IMT- 2020/5G etc. (supplementary slide 3).

Network softwarization view of the 5G mobile networks Slice means a logical set of infrastructure resources (i.e., physical, logical, virtual resources) to enable functions and services of network. A slice is considered as a unit of programmable resources such as network, computation and storage. As 5G Mobile Network should cover wider variety of application domains, the concept of slicing should be extended from what are currently targeted by SDN/NFV technologies. TTC has contributed to the network softwarization related standardization in ITU-T SG13/Q21

IoT/M2M Promotion of oneM2M in Japan in cooperation with ARIB - Release2 Seminar in September 2016 in Tokyo - Support for Interoperabililty Test event in November 2016 in Kobe - oneM2M Showcase event #2 on March 2 2017 in Tokyo TTC Adhoc on IoT/Smart Cities and Communities, comprised of Multimedia Application WG, IoT Area Network WG, Connected Car WG, oneM2M WG, ICT & CC WG, Security WG, Network Vision WG and Signalling WG, is discussing how Japanese industry could contribute to the relevant standardization activities, especially in ITU-T SG20. This Adhoc played very important role in coordinating joint sector members proposal in supporting the transposition of oneM2M TS/TR of Release 2A into ITU-T Recommendations at SG20 meeting in September 2017.

IoT/M2M IoT Acceleration Consortium (http://www.iotac.jp/en/) was established in October 2015 by Ministries, namely MITI & MIC Japan, with the aim of creating an adequate environment for attracting IoT investment in the future through public-private collaboration. TTC is supporting a secretary role in the consortium. In addition, TTC has started to provide short-term IoT forum hosting service in June 2016. Here, the forum can be speedily set up at reasonable cost for the participants from different industries. Participation is open to non-TTC member and the participants can freely discuss about the IoT based new business.

IoT/M2M The detailed services we plan to provide are as follows: holding seminar and workshop (Information exchange, Idea exchange), holding human resource development seminar, and holding Ideathon and Hackathon supporting proof of concept and application development. The expected outcomes are to facilitate team building among different industries for business creation and to activate pre/post standardization process.

All IP – IMS Interconnection All IP Interconnection : 3GPP, GSMA PSTN migration to all IP networks (by year 2025) project in Japan VoIP/VoLTE interworking guideline between IMS (JJ-90.30) in cooperation with GSMA (GSM Association) ENUM (JJ-90.31) Number portability（JT-E164 Sup.2） VoLTE speech quality assessment guideline All IP Interconnection Adhoc, comprised of Signalling WG, 3GPP WG & Mobile Network Management WG, has been contributing to the realization of smooth transition from the existing PSTN to all IP networks.

TTC’s challenges Interests of ICT users are moving to services/applications where not only telecom operators but also OTT players are active. How to make our activity more attractive to not only existing ICT industry but also other industries using ICT services? How to increase TTC members and improve our financial environment? TTC has established IoT innovation promotion committee in I3C in June 2017, where various industry groups can form a forum (we call it IoT Working Party) across different IoT fields and discuss idea creation, business collaboration, etc., as shown in slide7&8. It is expected that their discussions would trigger new standardization activity in TTC.
