Question 3/20

​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.
