2 TTC WG restructuring TTC is responsible for ICT standardization except for radio and broadcasting issues in Japan. TTC is accredited by MIC to engage in upstream activity to ITU-T SG2, SG5, SG11, SG13, SG15, SG16, SG17, TSAG & RevCom. TTC introduced new WG grouping structure (5 Division) effective from April 2016 Future technical areas candidates: IMT-2020, SDN/NFV, Big Data, Industrial Internet, Connected Car, Disaster Relief, E-health and Accessibility etc. Preparation for WTSA-16 including APT WTSA Preparatory Group. TTC contributes to SG restructuring studies in ITU-T through Global Communication Advisory Group. Introduced special discount membership fee for SMEs or Academia (June, 2015) TTC’s 18 WGs and 5 Division structure

IoT (Internet of Things) 3 IoT (Internet of Things) IoT and its application (oneM2M, ITU-T SG20, etc.) IoT Acceleration Consortium was established in October 2015 in Japan with the aim of creating an adequate environment for attracting investment in the future with IoT through public-private collaboration. TTC will contribute to Smart IoT Acceleration Forum in the consortium. (Supplementary Slide-1) Promotion of oneM2M activity in Japan in cooperation with ARIB Established a new adhoc group to contribute to ITU-T SG20, IoT and its applications including smart cities and communities (SC&C) Provisional network support in disaster areas utilizing Vehicle communication(Supplementary Slide-2). The next CITS meeting will be hosted by TTC in July 2016 Future TTC working structure to cope with IoT issues including oneM2M, ITU-T SG20 and others

Future Mobile Networking 4 Future Mobile Networking ITU-T FG-IMT2020(Phase 2), 3GPP, Network Softwarization Started the study of IMT-2020/5G networking (Sept 2014 - March 2015) and developed White Paper on 5G networking URL: http://www.ttc.or.jp/e/topics/20150413/ The second phase of study was completed in September 2015, which identified the networking study issues such as network softwarization, mobile front/back-haul, mobile edge computing. (Supplementary Slide-3, 4) Support the Fifth Generation Mobile Communications Promotion Forum (5GMF) in Japan with keeping close collaboration with ARIB. Future TTC working structure to cope with IMT-2020 issues including 3GPP, ITU-T FG IMT-2020

5GMF Focus Areas in FG IMT-2020 (Supplement-3) 5GMF Focus Areas in FG IMT-2020 1. Overall Architecture Core FH/BH UE The focus areas for 5GMF representing in the matrix of system elements and layers. Slicing of Fronthaul/ Backhaul is new area of study in IMT-2020 network aspect. Infrastructure aspect of FH/BH is agreed to be handled in ITU-T SG15 Platform/ Middleware Applications 4.Edge Computing 5. Softwarized Data Plane (in support of e.g. ICN) 3. Horizontal Extension of Slicing 2. Vertical Extension of Slicing Slicing Infrastructure

Network softwarization view of the 5G mobile networks (Supplement-4) Network softwarization view of the 5G mobile networks   Slicing allows logically isolated network partitions (LINP) 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. Platform/Middleware Applications Slicing Infrastructure The 5G Mobile Networks viewed from slicing based model of Network Softwarization
