Question 3/20 - IoT functional architectures including signalling requirements and protocols
(Continuation of part of Question 1/11and part of Question 3/13)
As the Internet of Things (IoT) establishes its position as an underlying mechanism for various applications, special attention is being paid to how advanced information and communication technology (ICT) systems are designed based on IoT and related conceptual architectures including signalling requirements and protocol. Given the rich features of IoT, highly capable ICT systems meeting vertical industry demands, can be realized by supplementary development based on IoT architectures. This is a promising way in terms of efficiency and time to market.
To support this approach, the IoT architectures, their functionalities, data model and protocols have to be studied building also on existing Recommendations, including ITU-T Y.2060.
This Question addresses IoT functional architectures, signalling requirements and protocols needed to control network attachment procedures (including mobility management and authentication); to control session establishment and release, to control bearer resources (including quality of service control), to interact with services and applications and to interact with legacy networks.
Study items to be considered include, but are not limited to:
What new and revised framework and/or conceptual architecture Recommendations are required to realize convergence based on IoT?
What signalling and control architectures are required for IoT and SC&C?
- What capabilities of the signalling and control architectures are required to support services and/or applications of public interest during emergency situations?
- What capabilities of signalling and control architectures are required to provide energy savings?
- What enhancements to existing signalling requirements and protocols are required to support the Internet of things (IoT), machine-to-machine (M2M) communication services and/or applications?
- Collaboration with which standards developing organizations (SDOs) would be necessary to maximize synergies and harmonize existing standards?
Tasks include, but are not limited to:
Studies on general reference models on IoT and emerging industry needs;
Frameworks to identify the basic architectural compositions and views on IoT. These will be based on the identification of architectural requirements derived from the industry needs;
- Identification of entities, their functions, and reference points, required to provide support to IoT applications and services;
- Determine the requirements that the IoT signalling and protocols are intended to support. It is anticipated that these requirements will need to be periodically refined to reflect the evolution of IoT-related technologies taking into consideration the signalling requirements and protocols available from ITU-T and other SDOs;
- Identify modifications and enhancements to the signalling requirements and protocols that will enable them to meet the IoT requirements and architecture;
- Identify a set of physical interfaces for which interoperability between different IoT network elements is desirable and for which detailed signalling requirements need to be studied and control protocols need to be standardized. This includes middleware for interoperability between IoT applications for different IoT verticals;
- Identify data sets that will enable data interoperability for various verticals including SC&C;
- Define interworking with legacy systems;
- Study specific IoT signalling requirements and protocols such as peer-to-peer and mesh architectures;
- Providing the necessary collaboration for joint activities in this field within ITU and between ITU-T and SDOs, consortia and fora,
