10、ons specialized agency in 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
11、on them with a view to standardizing 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
12、 ITU-T Recommendations is 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
13、 used for conciseness to 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
14、 the Recommendation is achieved 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
15、 of any party. INTELLECTUAL 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
16、 Property Rights, whether 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. Howeve

21、064 (01/2014) 1 Recommendation ITU-T Y.2064 Energy saving using smart objects in home networks 1 Scope This Recommendation describes requirements and capabilities for saving energy by using smart objects in home networks. It develops the functional architecture of key components for saving energy th
22、rough home/building automation. This Recommendation covers the following: general overview for saving energy by using smart objects in home networks requirements and capabilities for saving energy by using smart objects in home networks functional architecture for saving energy by using smart object
23、s in home networks. This Recommendation considers the fixed home environment such as residential buildings, and it also considers aspects of the mobile environment relating to the home such as networked electric vehicles (EVs) which support ubiquitous networking among smart objects. 2 References The

29、he following terms defined elsewhere: 3.1.1 context ITU-T Y.2002: The information that can be used to characterize the environment of a user. 2 Rec. ITU-T Y.2064 (01/2014) NOTE Context information may include where the user is, what resources (devices, access points, noise level, bandwidth, etc.) ar
30、e 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. 3.1.2 object ITU-T Y.2002: An intrinsic representation of an entity that is described at an appropriate level of abstraction
31、in terms of its attributes and functions. NOTE 1 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 object is informally said to perform functions and offer services
32、(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 one function. A function can be performed by the cooperation of s
33、everal objects. NOTE 2 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.), information devices (e.g., content delivery server), products, contents, and resources. 3.
34、1.3 ubiquitous networking ITU-T Y.2002: The ability for persons and/or devices to access services and communicate while minimizing technical restrictions regarding where, when and how these services are accessed, in the context of the service(s) subscribed to. NOTE Although technical restrictions to
35、 access services and communicate may be minimized, other constraints such as regulatory, national, provider and environmental constraints may impose further restrictions. 3.2 Terms defined in this Recommendation This Recommendation defines the following term: 3.2.1 smart object: An object which is a
36、ware of its characteristics, context and situation. It shares and processes information, such as its identity, current location, physical properties and the information it senses from its surroundings, while performing object-to-object communications. NOTE ITU-T Y.2002 and ITU-T Y.2062 provide detai
37、ls of object-to-object communication. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: BAN Building Area Network BAS Building Automation System BEMS Building Energy Management System DR Demand Response EMS Energy Management System ESI Energy Service Int

40、o deviation is permitted, if conformance to this Recommendation is to be claimed. The keywords “is prohibited from“ indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed. The keywords “is recommended“ i
41、ndicate a requirement which is recommended but which is not absolutely required. Thus, this requirement need not be present to claim conformance. The keywords “is not recommended“ indicate a requirement which is not recommended but which is not specifically prohibited. Thus, conformance with this Re
42、commendation can still be claimed even if this requirement is present. The keywords “can optionally“ indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendors implementation must provide the option, and
43、 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 this Recommendation. 6 Overview of energy saving using smart objects in home networks Home networks ITU-T Y.2291 provide pa
44、cket-based transfers (in particular support of Internet protocol (IP) and user access to a wide range of services and applications in a seamless environment, using multiple broadband and quality of service (QoS)-enabled transport technologies. They support automatic discovery and management of fixed
45、 and mobile terminals to the home network. Energy issues such as low-power consumption are central to the ubiquitous network environment ITU-T Y.2002 of the Internet of things (IoT) ITU-T Y.2060. For devices which constrain and minimize energy consumption, there are significant efforts being made to
46、 implement autonomous smart objects and to develop their applications which relate to energy issues. Home networks play an important role in interconnecting smart objects with the Internet. In the ubiquitous network environment, everything is becoming connected. Therefore, a network has evolved from
47、 being primarily a source of information to being the platform for all types of applications. Smart and connected communities using the “connecting to anything“ capability of ubiquitous networking ITU-T Y.2002 play an important role in applications and services. Therefore, one of the core applicatio
48、ns for interdisciplinary fusion services that this Recommendation focuses on is the requirements and key functionalities for saving energy using smart objects through combining information technology (IT) and other technologies (e.g., from energy related industries) in home networks. 4 Rec. ITU-T Y.
49、2064 (01/2014) Figure 1 depicts energy saving using smart objects; it shows a diagram of home networks with examples of smart objects. In the fixed home environment (e.g., residential buildings), objects such as energy saving systems, smart meters and home automation controllers, are used for energy management. In the mobile environment (e.g., networked EVs), objects such as devices for navigation and/or safety are used for saving energy. Figure 1 Energ
