10、n ITU-T Y.4552/Y.2078 Application support models of the Internet of Things Summary Recommendation ITU-T Y.4552/Y.2078 provides application support models of the Internet of things (IoT). This Recommendation describes the basis of IoT application support models: the configurable application support m
11、odel, the adaptable application support model and the reliable application support model. These three application support models are described in functional view, implementation view and deployment view, in order to identify, respectively, the configurable capabilities, the adaptable capabilities an
12、d the reliable capabilities for support of IoT applications having some characteristic requirements. This Recommendation describes the IoT configurable capabilities that extend the IoT basic capabilities specified in Recommendation ITU-T Y.4401/Y.2068 in order to enable the IoT applications to confi
13、gure the IoT capabilities based on their characteristic requirements. This Recommendation describes the IoT adaptable capabilities that extend the IoT basic capabilities specified in Recommendation ITU-T Y.4401/Y.2068 in order to enable the IoT applications to adapt to the IoT capabilities based on
14、their characteristic requirements. This Recommendation describes the IoT reliable capabilities that extend the IoT basic capabilities specified in Recommendation ITU-T Y.4401/Y.2068 in order to support the IoT applications by the IoT capabilities with required degrees of reliability for fulfilling t
15、heir characteristic requirements. Use cases from the smart home environment provide examples about the usage of the IoT application support models.

ITU-T Y.4552/Y.2078 (02/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). T
18、he 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 standardizing telecommunications on a worldwide basis. The World Telecommunication Stand
19、ardization 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
20、 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 indicate both a telecommunication administration and a recognized operating agency. Co
21、mpliance 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
22、 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. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implemen
23、tation 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, whether asserted by ITU members or others outside of the Recommendation development process. A
24、s 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 cautioned that this may not represent the latest information and are therefore strongly urge
25、d to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2016 All rights reserved.

32、ble application support model, the adaptable application support model and the reliable application support model. The three application support models are specified in functional view, implementation view and deployment view respectively. The configurable capabilities, adaptable capabilities and re
33、liable capabilities related, respectively, to each of the three models, are also identified and described. The scope of this Recommendation includes: The basis of application support models; The functional view, the implementation view and the deployment view of the configurable application support
34、model and related configurable capabilities that extend the IoT basic capabilities specified in ITU-T Y.4401 to enable the IoT applications to configure the IoT capabilities based on their characteristic requirements; The functional view, the implementation view and the deployment view of the adapta
