Fields of activity: E TSI ISG ZSM, O-RAN WG10Autonomous Network and Service Management
I am delighted to receive the Encouragement Award from the
ITU Association of Japan. I greatly appreciate the support of mycolleagues in ETSI ISG ZSM and my company.
I have been involved in ETSI ISG ZSM since 2018 andthis was my first standardization activity. In ETSI ZSM, weaim to realize full end-to-end autonomous networks and service
management. It has become an urgent necessity to realize
the autonomous networks because networks are getting more
complex and the number of experienced maintainers is decreasing.
Although achieving our goal in a short time will be difficult,
we need a standard specification for autonomous networks. We
have been actively discussing and have already published many
specifications toward this goal.
One particular specification that I focused on was for Closed
loop models required for lifecycle management of closed loops,
which is covered in GS ZSM009-1 Closed-Loop Automation. Itook the lead in organizing many ad hoc meetings and received

cooperation and support from many colleagues across different
companies. At the plenary session there were many opposing
opinions and we had difficulty getting our contributions approved,
but we discussed it together cooperatively and finally they wereapproved.
Recently we have started studying new fields such as Intentdriven Autonomous Networks and Network Digital Twins, formore- autonomous networks. With Intent-driven Autonomous
Networks we could realize a world where systems automatically
perform maintenance and operation by inputting declarative
statements. Please join ETSI ISG ZSM if you would like to get
involved in standardization activities for this kind of advanced
technologies.
Finally, my current focus is on ETSI and O-RAN work, andI hope to work with ITU and many other standards organizationsin the future.

Fields of activity: ITU-T SG17, ITS security

Collaborative work at ITU-T aiming to create secure ITS for the future
At this time, I would like to express my deep appreciation onreceiving an ITU-AJ Encouragement Award. I would also liketo thank the many people at ITU-AJ who have offered me theirvaluable assistance and cooperation in past activities.
I have had the opportunity since 2018 to participate instandardization activities in relation to Intelligent Transport
Systems (ITS) in ITU-T SG17. Specifically, I have beenengaged in the creation of Recommendations that stipulate therequirements for appropriate measures to defend against security
threats to the various types of data exchanged in Vehicle toEverything (V2X) communications, in which an automobile
equipped with communication functions (Vehicle) communicateswith other vehicles, transport infrastructure facilities, and ICT
services (Everything).
In this work, proposals are received not only from telecom
operators but also from automobile manufacturers, suppliers,Fumito Ito

and other parties. As a result, conflicts can arise in the processof compiling proposals from multiple parties with different roles
and expectations into a single Recommendation. Nevertheless,by extracting the ideas and grounds behind those proposals andnegotiating patiently to obtain mutual understanding and consent,
I was able to make progress in this work. I was greatly impressedwith the sincere efforts of multiple parties to collaborate based on
the common objective of creating secure ITS for the future.
Since May 2022, I have been serving as associate rapporteurof Question 13 in ITU-T SG17. I would like to continue in thisactivity while collaborating closely with all concerned. In addition,
I would like to serve as a source of support for others involvedin standardization activities based on my own experiences inreceiving assistance from many of my seniors. With this in mind,
I will make every effort to fulfill my duties in returning the resultsof R&D in advanced technologies to society.

Activities for Revision of Recommendations related to UHDTV-FPU
It is a great honor to receive the Encouragement Award fromthe ITU Association of Japan. I would like to express my sincere
gratitude to the ITU-AJ and everyone that has given me guidanceand encouragement.
Radio systems are indispensable in the production of broadcast
programs, such as a live broadcast from the scene of an incident orlive production of a marathon race. Program transmission systems
for broadcasting are called Field Pick-up Units (FPUs). In Japan,
microwave band FPUs (5 to 7 GHz band and 10 to 13 GHzband) and millimeter wave band FPUs (42 GHz band), which
can transmit 4K/8K UHDTV (Ultra-high-definition Television)
programs, have been standardized and are already in operation. In
ITU-R, the system characteristics of television outside broadcast
are described in the Recommendation F.1777 in the fixed service
and the Recommendation M.1824 in the mobile service. I haveworked on revision of both Recommendations, to add the latest
FPU characteristics for UHDTV in WP5A and WP5C.

20New Breeze Autumn 2022

I first drafted the revision of Recommendation F.1777 around
March 2020. Then I further revised the draft with suggestions
and advice through the domestic deliberations and submitted
the contribution to WP5C in July 2020. The Japanese proposal
was output successfully as a working document. A contribution
proposing a revision of M.1824 was submitted to the WP5A
meeting in November 2020, and since then, revision work wascarried out in parallel in the WP5A and WP5C meetings. Thanks
to the cooperation of the Japanese delegation, the deliberations
proceeded smoothly and both recommendations were revised inFebruary 2022.
I hope that these revisions of the Recommendations willreflect Japan’s advanced efforts regarding program transmission
systems for UHDTV and will be helpful for sharing studies ofimportant radio systems. With this valuable experience, I willcontinue to contribute to promotion and standardization of R&Dresults.

International standardization and creating highly compatible IPinterconnect standards between IMS operators in Japan
It is a great honor to receive this ITU-Association of JapanEncouragement Award. I would like to offer sincere thanks toeveryone at the ITU-AJ and the many others who have given theirguidance and support.
I have been involved in standardization of IMS interoperator Network-to-Network interface specifications at 3GPP
since 2011. This is part of IMS, which has been adopted as theIP multimedia communication specification since IMT- 2000
by ITU. The objective of this work was to create a domestic
specification for IP interconnection between the networks ofdomestic telephone operators in Japan, while also maintaining
consistency with international standards. We have participatedin both domestic and international standardization processes tocreate these standards. During the four years from 2017 to 2021
as the vice-chair of the 3GPP CT3 WG, I was also involvedin standardization of the 5G Core Network specifications, theNorthbound API specifications and others, in addition to work on
IMS specifications. These were also very valuable experiences.

Yuichiro Okugawa

A particularly difficult issue during these activities was how
to resolve differences that arose between domestic requirements
and international specifications. Often it could take deliberation
over six months or more, just to add or change a short description
in a signalling specification. However, building arguments andholding discussions with other participants toward resolving such
issues is the whole point of standardization, and the experienceand personal connections gained through that activity are valuableassets.
Currently at 3GPP, service requirements, architecture, andprotocol specifications for 5G Advanced and Beyond 5G are being
studied. One part of this work related to IMS and voice services isthe Real Time Communication specification, which will provide
AR/VR and is promising for developing future communicationservices. I hope to continue working and contributing to studyof new specifications and international standardization in thetelecommunications industry as it continues to develop.

Fields of activity: ITU-T SG5

Standardization activities in the field of telecommunications EMC
I am very thankful to be receiving this encouragement award
from an organization with the history and prestige of the ITU
Association of Japan. I would also like to thank everyone for theirsupport of activities in ITU-T SG5.
I have been participating in ITU-T SG5 activities since2011, involved in revisions of various recommendations in
the telecommunication EMC field. In this work, most of myfocus was on establishing the Recommendation, “Method forradiated immunity testing anticipating use of radio devices neartelecommunications equipment.”
In the past, there were cases when radio waves emitted
by mobile phones used nearby interfered with operationof communication equipment, so for many years, use wasdiscouraged. However, considering the proliferation ofsmartphones and tablets and the need to optimize equipment

maintenance work, more recently it has become necessary
to clearly def ine emission immunit y requirements forcommunications equipment taking into account that radio devices
could be used nearby.
Cla rif y ing these technica l requirements involved
performing emission immunity tests on approximately 300
types of communication equipment, conducting simulations todefine the requirements, liaising with IEC, and holding many
discussions with participants over roughly two years before theRecommendation was completed. We achieved this goal throughsteady effort and through it I gained great experience and growth.
Building on this experience in the future, I will continue tocontribute to standardization activities as an associate rapporteurfor SG5/Question 1, dealing with EMC issues that arise indevelopment of ICT technologies.
