ITU-T Y.2068 (03/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication S
12、tandardization 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 Standardization Assembly (WTSA)
13、, 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 technology which fall wit
14、hin 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 with this Recomme
15、ndation 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 obligatory language such
16、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 this Recommendat
17、ion 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 date of approval
18、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 consult the TSB paten

37、n technologies. NOTE 1 Through 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 From a broader per
38、spective, the IoT can be perceived as a vision with technological and societal implications. 3.1.5 next generation network (NGN) b-ITU-T Y.2001: A packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in whi
39、ch service-related functions are independent from underlying transport-related technologies. It enables unfettered access for users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of
40、 services to users. 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 world (virtual things), which is capable of being identified and integrated into communication networks. 3.2 Terms defined in this Recomme
41、ndation None. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: IoT Internet of Things MMCF Mobility Management and Control Functions NACF Network Attachment Control Functions NGN Next Generation Network QoS Quality of Service RACF Resource and Admission
42、 Control Functions TaaS Things as a Service 5 Conventions In this Recommendation: The keywords “is required to“ indicate a requirement which must be strictly followed and from which no deviation is permitted if conformance to this document is to be claimed. Rec. ITU-T Y.2068 (03/2015) 3 The keywords
43、 “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 recom
44、mended. 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.
45、 6 Concepts of the IoT functional framework 6.1 Openness and interoperability of the IoT capabilities The openness of the IoT capabilities refers to opening the networking and service-provisioning functionalities of the IoT to stimulate the innovation ability for IoT technologies and applications de
46、velopment. Through an open, shared, collaborative approach, IoT applications can be developed effectively for business, industry, and social community. The openness of IoT capabilities can be realized by encapsulating IoT capabilities into service-provisioning interfaces. The “open IoT capabilities“
47、 refer to the set of the IoT capabilities that are required to be opened to IoT applications or users. These IoT capabilities should have open interfaces that can be accessed by IoT applications or users. The interoperability of the IoT capabilities can be realized by specifying the service-provisio
48、ning interfaces in a standardized way. The “interoperable IoT capabilities“ refer to the set of the IoT capabilities that are required to interact between different IoT functional elements, especially when deployed by different service providers. These IoT capabilities are distributed across differe
49、nt functional elements, and collaboration between these different functional elements fulfils their functionalities. 6.2 Completeness, implementability and applicability of the IoT capabilities The completeness of the IoT capabilities refers to the fact that the whole set of IoT capabilities can fulfil all the common requirements of the IoT ITU-T Y.2066. NOTE There may not be one-to-one mapping between IoT common requirements and IoT capabilities (i.e., one common require
