IT in general

This Recommendation defines the reference framework and high-level requirements of smart city platforms. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published. The reference to a document within this Recommendation does not give it, as a stand-alone document, the status of a Recommendation.

An object identifier (OID) is an identifier to name an object in a hierarchically assigned namespace. In the Internet of things (IoT), thousands of IoT resources will be intricately provided as fusion types of various services. For the thousands of IoT resources, object identifiers (OIDs) can provide a resolution framework with unlimited scalability. On the other hand, IoT resources need to secure their data, so the distributed ledger technology (DLT) can guarantee its integrity. In consequence, the convergence of DLT and OIDs provides a good solution for identifying secured data of IoT resources. Recommendation ITU-T Y.4476 therefore specifies a resolution framework for the transactions of a distributed ledger assigned to IoT resources. Recommendation ITU-T Y.4476 also describes the concepts, functional requirements, architecture and procedures of an OID-based resolution framework by using DLT.

Along with the development of the Internet of things (IoT) and smart cities and communities (SC&C), various applications have different kinds of requirements for data management, and there are many challenges, especially in data representing, data processing, data service provisioning, and other aspects in a secure and effective manner. Meanwhile, blockchain as an emerging technology possesses the characteristics of trust, transparency, traceability and accountability. It has the potential capabilities to solve the existing issues in data management. Recommendation ITU-T Y.4561 specifies the requirements, generic reference model, common capabilities, and procedures of blockchain-based data management.

Blockchain is an emerging technology, its most important characteristics are traceable, un-erasable, immutable, and time-stamped. It is able to efficiently ensure integrity, authenticity, and auditability for all transactions. Blockchain has important impacts and benefits for data exchange and sharing in support of Internet of things (IoT) and smart cities and communities (SC&C). In most of the IoT and SC&C scenarios, it is necessary to ensure data processing, circulation, sharing and management for all trust operations. Blockchain technologies can meet these needs. Recommendation ITU-T Y.4560 specifies the requirements, functional models, a platform, and deployment modes of blockchain-based data exchange and sharing for supporting IoT and SC&C.

This document specifies a generic business process framework for a smart city focusing solely on smart city-specific processes. Generic business processes common between smart cities and commercial organizations are be identified but not detailed.

Currently e-health systems are being implemented by governments and stakeholders to increase the effectiveness, efficiency and the quality of health care services. The Internet of things (IoT) as a relatively new technology is transforming e-health systems to further enhance health care services. However, this transformation concomitantly creates a need for effective performance evaluation frameworks of e-health systems in the IoT.

Recommendation ITU-T Y.4908 addresses this need for effective performance evaluation frameworks of e-health systems in the IoT and includes:
- A classification of e-health services in the IoT.
- A non-exhaustive set of non-functional performance evaluation factors applicable to the e-health systems in the IoT.
- Performance evaluation frameworks for e-health systems in the IoT.

ISO/TS 21089:2018 describes trusted end-to-end flow for health information and health data/record management. Health data is originated and retained, typically as discrete record entries within a trusted electronic health record (EHR), personal health record (PHR) or other system/device. Health data can include clinical genomics information.Health record entries have a lifespan (period of time managed by one or more systems) and within that lifespan, various lifecycle events starting with (1) originate/retain. Subsequent record lifecycle events may include (2) update (3) attest (4) disclose (5) transmit (6) receive (7) access/view, and more. A record entry instance is managed over its lifespan by the source system. If record entry content is exchanged, this instance may also be managed intact by one or more downstream systems. Consistent, trusted management of record entry instances is the objective of this document, continuously and consistently whether the instance is at rest or in motion, before/during/after each lifecycle event, across one or more systems.

This standard defines a suite of cryptographic protocols supporting the protection of Electric Power System communications links. It does not address specific applications or hardware implementations, and is independent of the underlying communications protocol.

This Recommendation introduces the concept of blockchain-based unified key performance indicator data management for smart sustainable cities (BKDMS), analyses its common characteristics and high-level requirements, defines a reference architecture of BKDMS and relevant common capabilities，gives a common data structure of KPIs according to the KPIs definition of the ITU-T Y.4900 series.The scope of this Recommendation does not include:• The KPIs definition.• The KPI data value and scope.• Specific technical implementation mechanism of blockchain.

Alert messages need to be presented to users affected by possible alerts in a way that they can be readily understood and required actions can be taken. It is obvious that the presentation of these alert messages needs to be fully accessible for the largest possible user community, including people with specific requirements and elderly people with multiple impairments. The proposed Technical Report will summarize guidelines and good practice proposals to the design process of the user interface for the presentation of alert message on a wide range of end user devices in a fully accessible manner. SC EMTEL and TC HF will work in close cooperation to produce this TR.
