ITU-T Y.2066 (06/2014) i Recommendation ITU-T Y.2066 Common requirements of the Internet of things Summary Recommendation ITU-T Y.2066 provides the common requirements of the Internet of things (IoT). These r
8、equirements are based on general use cases of the IoT and IoT actors, which are built from the definition of IoT contained in Recommendation ITU-T Y.2060. The common requirements of the IoT are independent of any specific application domain, which refer to the areas of knowledge or activity applied
9、for one specific economic, commercial, social or administrative scope, such as transport application domain and health application domain. This Recommendation builds on the overview of IoT (Recommendation ITU-T Y.2060), developing the common requirements based on general use cases of the IoT and the
10、 IoT actors and taking into account important areas of consideration from a requirement perspective. Some representative use cases of the IoT, which are abstracted from application domains, are also provided. The common requirements of the IoT specified in this Recommendation are classified into the
11、 categories of non-functional requirements, application support requirements, service requirements, communication requirements, device requirements, data management requirements and security and privacy protection requirements.

ITU-T Y.2066 (06/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Te
14、lecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardizatio
15、n Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technolo
16、gy which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance
17、with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligato
18、ry language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of
19、 this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the
20、date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to cons

27、commendation provides the common requirements of the Internet of things (IoT). These requirements are based on general use cases of the IoT and IoT actors, which are built from the definition of IoT contained in ITU-T Y.2060. The common requirements of the IoT are independent of any specific applica
28、tion domain, which refer to the areas of knowledge or activity applied for one specific economic, commercial, social or administrative scope, such as transport application domain and health application domain. This Recommendation builds on the overview of IoT ITU-T Y.2060, developing the common requ
29、irements based on general use cases of the IoT and IoT actors and taking into account important areas of consideration from a requirement perspective. The common requirements of the IoT specified in this Recommendation are classified into the categories of non-functional requirements, application su
30、pport requirements, service requirements, communication requirements, device requirements, data management requirements and security and privacy protection requirements. The scope of this Recommendation includes: general use cases of the IoT IoT actors important areas of consideration from a require
31、ment perspective common requirements of the IoT. The common requirements of the IoT are summarized and numbered in Annex A. Some representative use cases of the IoT, which are abstracted from application domains, are provided in Appendix I. NOTE Regulatory, legal and business aspects are outside the
32、 scope of this Recommendation. Protocol and interface related requirements (e.g., for the control and management aspects of IoT) are also outside the scope of this Recommendation. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in thi

NOTE 1 Thro
39、ugh the exploitation of identification, data capture, processing and communication capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring that security and privacy requirements are fulfilled. NOTE 2 In a broad perspective, the IoT can be percei
40、ved as a vision with technological and societal implications. 3.1.5 service ITU-T Y.2091: A set of functions and facilities offered to a user by a provider. 3.1.6 thing ITU-T Y.2060: With regard to the Internet of things, this is an object of the physical world (physical things) or the information w

The keyword
45、s “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance. The keywords “can optionally“ and “may“ indicate an optional requirement which is permissible, without implying any sense of being reco
46、mmended. These terms are not intended to imply that the vendors implementation must provide the option and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with the specification
47、. 6 General use cases of the IoT and IoT actors This clause describes general use cases of the IoT and IoT actors and the relations among general use cases and IoT actors. An IoT actor specified in this Recommendation refers to an entity that is external to the IoT and that interacts with the IoT. 6
48、.1 General use cases The general use cases are built from the definition of IoT contained in ITU-T Y.2060. According to the definition of IoT, given in ITU-T Y.2060, IoT enables “advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable informati
49、on and communication technologies“. This implies that the IoT interconnects things to sense or actuate things and to provide advanced services, so the general use cases of “IoT sensing or actuating“ and “IoT service provision“ can be derived. According to the definition of IoT, as given in ITU-T Y.2060, “Through the exploitation of identification, data capture, processing and communication capabilities, the IoT makes full use of things to offer services to all kin
