ITU-T Y.3041 (04/2013) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunicati

11、on 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 Standardization Assembly (W

12、TSA), 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

13、 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 with this Rec

14、ommendation 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 s

15、uch 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 RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recomm

16、endation 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 appr

17、oval 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

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

25、 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.

27、T X.1161: Information created by individuals, institutions and technology to benefit audiences in contexts that they value. 3.1.2 context b-ITU-T Y.2002: The information that can be used to characterize the environment of a user. NOTE Context information may include where the user is, what resources

28、 (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 context awareness b-ITU-T Y.2201: Context awareness is a capa

29、bility to determine or influence a next action in telecommunication or process by referring to the status of relevant entities, which form a coherent environment as a context. 2 Rec. ITU-T Y.3041 (04/2013) 3.1.4 fair usage ITU-T Y.3042: Equal treatment for the same service(s), including application(

30、s), between different users (e.g., end-user applications) with the same service level agreement (SLA). 3.1.5 object b-ITU-T Y.2002: An intrinsic representation of an entity that is described at an appropriate level of abstraction in terms of its attributes and functions. NOTE 1 An object is characte

31、rized 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 (an object which makes a function available is said to offer a service

32、). 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 several objects. NOTE 2 Objects include terminal devices (e.g., used by

33、 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. 3.1.6 thing b-ITU-T Y.2060: With regard to the Internet of things, this

34、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 Recommendation This Recommendation defines the following term: 3.2.1 smart ubiquitous networks (S

35、UN): IP-based packet networks that can provide transport and delivery of a wide range of existing and emerging services to people and things. The services provided by the SUN can cover aspects such as control, processing and storage. NOTE 1 The network is smart in the sense that it is knowledgeable,

36、 context-aware, adaptable, autonomous and programmable, and can perform services effectively and securely. NOTE 2 The network is ubiquitous in the sense that it allows access anytime, anywhere, through varied access technologies, access devices, including end-user devices, and human-machine interfac

40、 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“ indicate a requirement which is recommended

41、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 Recommendation can still be claimed even if t

42、his 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 the feature can be optionally enabled by t

43、he network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with this Recommendation. 6 Necessity of the SUN Because of developments in information and communications technology (ICT), many end-user devices, networks and services h

44、ave been acquiring more complicated features and capabilities. Telecommunication infrastructures, especially IP-based infrastructures, have been continuously requested to extend capabilities to meet requirements for such complicated features. At the same time, operators and providers are increasingl

45、y demanding with regard to efficient and productive use of their resources. This clause provides background information of the current telecommunication industry and the motivation for requiring capabilities, which are referred to as the SUN in clause 7. 6.1 Smart and ubiquitous devices ICT developm

46、ents have had a wide impact in telecommunications in general, and especially on end-user devices in terms not only of their physical appearance (e.g., size and media display), but also of their services and applications (including communication capabilities such as multiple network connections). Dev

47、ices termed as “smart“ are already available, generating smart and ubiquitous environments. The first device is the smartphone, providing a communication and service platform for an individual person. The second device is the smart TV, being a media gateway for an end-user living environment. The th

48、ird device is the smart small device such as the sensor and actuator, providing connections to anything. Smartphones are one of the key drivers in creating smart and ubiquitous environments, with their extended features including “always-on“ connections. Smartphones use mobile accesses (e.g., 2G, 3G

49、 or 4G) and/or wireless accesses (e.g., WiFi and WiMax) in a separate and/or integrated manner (i.e., the multiple-connection capability). Powerful processing with a high-resolution tiny camera 4 Rec. ITU-T Y.3041 (04/2013) allows an end user to become a prosumer (producer and consumer) for multimedia contents. The tiny-device technology (e.g., reading bar codes and sensor signals) allows the smartphones to be used for ubiquitous connection environments such as ubiquitous sensor networks (USNs). Such multi
