ITU-T Y.2069 (07/2012) i Recommendation ITU-T Y.2069 Terms and definitions for the Internet of things Summary Recommendation ITU-T Y.2069 specifies the terms and definitions relevant to the Internet of things (IoT) from an ITU
8、-T perspective, in order to clarify the Internet of things and IoT-related activities. History Edition Recommendation Approval Study Group 1.0 ITU-T Y.2069 2012-07-29 13 ii Rec. ITU-T Y.2069 (07/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency i
9、n the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication 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 s
10、tandardizing telecommunications on a worldwide basis. The World Telecommunication Standardization 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 i
11、s covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology 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
12、 indicate both a telecommunication administration and a recognized operating agency. Compliance 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 a
13、chieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory 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. INTELLECT
14、UAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of 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, whethe
15、r asserted by ITU members or others outside of the Recommendation development process. As of the 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 caut
16、ioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2012 All rights reserved.

ITU-T Y.2069 (07/2012) 3 Definitions 3.1 Terms defined elsewhere This
26、 Recommendation uses the following terms defined elsewhere: 3.1.1 actuator ITU-T Y.2061: A device that triggers a physical action following stimulation by an input signal. NOTE (from ITU-T Y.2061) As examples, an actuator might act on the flow of a gas or liquid, or electricity, through a mechanical
27、 operation. Dimmers and relays are examples of actuators. The decision to activate the actuator may come from an MOC application, human or MOC devices and gateway. 3.1.2 context ITU-T Y.2002: The information that can be used to characterize the environment of a user. NOTE (from ITU-T Y.2002) Context
28、 information may include where the user is, what resources (devices, access points, noise level, bandwidth, etc.) are near the user, at what time the user is moving, interaction history between person and objects, etc. According to specific applications, context information can be updated. 3.1.3 dev
29、ice ITU-T Y.2060: In the Internet of things, a piece of equipment with the mandatory capabilities of communication and the optional capabilities of sensing, actuation, data capture, data storage and data processing. 3.1.4 ID tag ITU-T Y.2213: A physical object which stores one or more identifiers an
30、d optionally application data such as name, title, price, address, etc. NOTE 1 (from ITU-T Y.2213) Depending on its implementation, it may have a communication capability with an ID terminal. NOTE 2 The same term is also defined in ITU-T F.771. 3.1.5 ID terminal ITU-T Y.2213: A device with a data re
31、ading and optional writing capability which reads (and optionally writes) identifier(s) and optionally application data from/into an ID tag. NOTE 1 (from ITU-T Y.2213) The data reading (and optionally writing) capability depends on its implementation. NOTE 2 The same term is also defined in ITU-T F.
32、771. 3.1.6 identifier ITU-T Y.2091: An identifier is a series of digits, characters and symbols or any other form of data used to identify subscriber(s), user(s), network element(s), function(s), network entity(ies) providing services/applications, or other entities (e.g., physical or logical object
33、s). Identifiers can be used for registration or authorization. They can be either public to all networks, shared between a limited number of networks or private to a specific network (private IDs are normally not disclosed to third parties). NOTE The same term is also defined in ITU-T F.771. 3.1.7 i
34、dentifier resolution ITU-T Y.2213: A function to resolve an identifier into associated information (see “Forward identifier resolution“) and vice versa (see “Reverse identifier resolution“). NOTE A similar term “ID resolution“ is defined in ITU-T F.771. 3.1.8 identifier scheme ITU-T Y.2213: It is a
35、numbering scheme that specifies the format and structure of the identifiers used within that scheme. 3.1.9 Internet of things (IoT) ITU-T Y.2060: A global infrastructure for the information society enabling advanced services by interconnecting (physical and virtual) things based on existing and evol
36、ving, interoperable information and communication technologies. NOTE 1 (from ITU-T Y.2060) From a broad perspective, the IoT can be perceived as a vision with technological and societal implications. Rec. ITU-T Y.2069 (07/2012) 3 NOTE 2 (from ITU-T Y.2060) Through the exploitation of identification,
37、 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. 3.1.10 machine-oriented communication (MOC) ITU-T Y.2061: A form of data communication betw
38、een two or more entities in which at least one entity does not necessarily require human interaction or intervention in the process of communication. 3.1.11 machine-to-machine applications ITU-T Y.2240: Applications enabled by the communication between two or more machines that need limited or no di
39、rect human intervention. NOTE The major subject of ITU-T Y.2240 is the NGN service integration and delivery environment in which M2M is considered as one of the possible use cases. At the time of approval, M2M and its definition were under study in ITU-T. The definitions of M2M may be modified accor
40、ding to the study. 3.1.12 meter ITU-T Y.2061: A device that measures and optionally records the quantity, degree, or rate of something, e.g., the amount of electricity, gas, or water used. NOTE (from ITU-T Y.2061): A meter is responsible for measuring the total amount of something consumed in a give
41、n period. 3.1.13 multimedia information ITU-T F.771: Multimedia information is digital information that uses multiple forms of information content and information processing, such as text, pictures, audio, video, three-dimensional panoramic pictures and digital maps to inform or entertain users. 3.1
42、.14 multimedia information delivery function ITU-T F.771: A multimedia information delivery function is a function for delivering multimedia information to an ID terminal which is triggered by tag-based identification. 3.1.15 object ITU-T Q.1300: An intrinsic representation of an entity that is desc
43、ribed at an appropriate level of abstraction in terms of its attributes and functions. NOTE 1 (from ITU-T Y.2002) An object is characterized by its behaviour. An object is distinct from any other object. An object interacts with its environment including other objects at its interaction points. An o
44、bject is informally said to perform functions and offer services (an object which makes a function available is said to offer a service). For modelling purposes, these functions and services are specified in terms of the behaviour of the object and of its interfaces. An object can perform more than
45、one function. A function can be performed by the cooperation of several objects. NOTE 2 (from ITU-T Y.2002) Objects include terminal devices (e.g., used by a person to access the network such as mobile phones, personal computers, etc.), remote monitoring devices (e.g., cameras, sensors, etc.), infor
46、mation devices (e.g., a content delivery server), products, contents, and resources. 3.1.16 open application interface ITU-T F.744: An interface used by USN applications to access USN middleware. NOTE This definition is associated with USNs, but it can be applied to the interfaces between the applic
47、ation layer and the service support/application support layer. 3.1.17 processed data ITU-T F.744: Data that is processed from raw sensed data by sensor network or USN middleware. NOTE This definition is associated with USNs, but it can be applied to other use cases of the IoT. 3.1.18 real-world enti
48、ty ITU-T F.771: A real-world entity is a physical and logical entity which mainly acts or is used in the real world, such as a physical object, logical object, place or person. Examples of physical objects include a water bottle, book, desk, wall, chair, tree, animal, cloth, food, television, light
49、and so on. Examples of logical objects include digital content such as a video, movie, music or story. Examples of places include a room, corridor, road, gate, garden and so on. The real-world entity concept includes both networked entities and non-networked entities. 3.1.19 sensed data ITU-T F.744: Data sensed by a sensor that is attached to a specific sensor node. 4 Rec.
