OPEN STANDARDS LANDSCAPE MEETING
13 MAR 2019

2. IOT AND SMART CITIES OPEN STANDARDS COMMITTEE
IEEE IOT OSC STANDARDS LANDSCAPE MEETING
There are a lot of different Standards Development
Organisations (SDOs) working on IoT and Smart City
related standards (ITU-T, ISO, ISO/IEC, JTC1, etc.) along
with many consortia, and there is a wide variety of very
different topics that are included – spectrum, software,
data, sensors, etc.
This presentation is part of the “IEEE IoT OSC Standards
Landscape Meeting” and aims to present an overview
about what is being discussed at Question 3 of ITU-T
Study Group 20 - IoT, Smart Cities and Communities.

3. IOT AND SMART CITIES OPEN STANDARDS COMMITTEE
ITU-T STUDY GROUP 20: INTERNET OF THINGS, SMART CITIES AND COMMUNITIES
Study Group 20 is working to address the standardization
requirements of Internet of Things (IoT) technologies, with an
initial focus on IoT applications in smart cities and communities
(SC&C).
SG20 develops international standards to enable the
coordinated development of IoT technologies, including
machine-to-machine communications and ubiquitous sensor
networks. A central part of this study is the standardization of
end-to-end architectures for IoT, and mechanisms for the
interoperability of IoT applications and datasets employed by
various vertically oriented industry sectors.

QUESTION 3/20 - ITU-T STANDARDS AT:
ARCHITECTURES, MANAGEMENT, PROTOCOLS AND QUALITY OF SERVICE
This Question addresses IoT functional architectures, protocols, management
mechanisms, and QoS (including performance) of IoT and Smart Sustainable Cities
and Communities (SC&C), which needed to construct architectural frameworks for
the following reasons:
‣ to control network attachment procedures (including mobility management);
‣ to control session establishment and release, to control network resources
(including QoS control);
‣ to interact with services and applications and to interact with legacy networks, etc.

8. IOT AND SMART CITIES OPEN STANDARDS COMMITTEE
Study items to be considered include, but are not limited to:
‣ What new and revised architectural framework Recommendations are required to realize IoT and SC&C?
‣ What technologies including networks, interfaces, functions, management mechanisms, as well as protocols are required for
the architecture of IoT and SC&C?
‣ What functionalities of the ICT technologies, signalling and control architectures are required to support services and/or
applications of IoT and SC&C?
‣ What enhancements to existing connectivities, interfaces, functions, management mechanisms and protocols are required to
support machine-to-machine (M2M) communication services and/or applications of IoT and SC&C?
‣ What performance requirements of connectivity technologies are required to support services and/or applications of IoT and
SC&C?
‣ What are the mechanisms for achieving QoS and its measurement principles required for IoT and SC&C?
‣ Collaboration with which standards development organizations (SDOs) would be necessary to maximize synergies and
harmonize existing standards?

Y.DEV-IOT-ARCH: ARCHITECTURAL REFERENCE MODEL OF DEVICES
FOR IOT APPLICATIONS
Source: CESAR / ITU-T Y.dev-IoT-arch (https://www.itu.int/itu-t/workprog/wp_item.aspx?isn=14655)
Processing power and communication capabilities define how the device communicates and
interacts with other entities in an IoT solution. By correlating the processing and
communication capabilities classifications, it is possible to enumerate three types of devices:
‣ Low processing and low connectivity device - LPLC device;
‣ Low processing and high connectivity device - LPHC device;
‣ High processing and high connectivity device - HPHC device.
This Recommendation describes the architectural reference model of devices for IoT
applications, based on a classification of devices defined by processing and communication
capabilities. The architectural reference model description also includes the device's
functional entities and the functional entities interaction for each device's architectural
reference model.
